What is the y-intercept of y = 50 - 1?
Answer:
49 or -1
Step-by-step explanation:
(im going to assume you meant y=50-1 and not y=50x-1)
The intercept would literally be 49 since 50-1=49
y=50x-1 would mean the y intercept is -1
Answer:
the y intercept is (0,49) Plz give branliest i need to level up
Step-by-step explanation:
50 - 1 = 49
y always equals 49
so the y axis is at x coordinate 0 and y intercept is at the y axis
so the point is (0,49)

A rectangle has an area of 80cm squared and a perimeter of 48cm find the length and width of the rectangle
2 possible solutions.
When width is 4 cm, length is 20 cm; When width is 20 cm, length is 4 cm
Step-by-step explanation:
Step 1: Let the width of the rectangle be x. Perimeter of the rectangle = 48 cm. Find expression for length.Perimeter of the rectangle = 2(length + width)
48 = 2(length + x)
24 = length + x
⇒ Length = 24 - x
Step 2: Find the dimensions if area = 80 cmArea of the rectangle = length × width
80 = x (24 - x)
80 = 24x - x²
x² - 24x + 80 = 0
x² - 20x - 4x + 80 = 0
x(x - 20) - 4(x - 20) = 0
(x - 4)(x - 20) = 0
⇒ x = 4, 20
24 - x = 20, 4
So there are two possible answers.
When width is 4 cm, length is 20 cm
When width is 20 cm, length is 4 cm
If the number of bacteria on the surface of your phone triples every hour and can be described with the exponential function f(x)=1,000⋅3x, complete the blank in the table of values to show how much bacteria is on your phone after 4 hours.
x f(x)
1 3,000
2 9,000
3 27,000
4 _[blank]_
Answer:
81,000
Step-by-step explanation:
1 1,000x3= 3,000
2 3,000x3= 9,000
3 9,000x3= 27,000
4 27,000x3= 81,000
The number of bacteria on your phone after 4 hours is 81,000.
Explanation:To calculate the number of bacteria on your phone after 4 hours using the exponential function f(x) = 1,000 * 3^x, we can substitute x with 4. So the equation becomes f(4) = 1,000 * 3^4.
Calculating this, we get f(4) = 1,000 * 81 = 81,000.

Ten students on student council are running for president, vice president, and
secretary. How many different permutations are there for the 3 positions?
Answer:
Step-by-step explanation:Using the word "HAPPY" (let's distinguish the P's as P1 and P2). ... The first person is the president , the 2nd is the Vice President and the 3rd is the Secretary so it ... Q-Four different items have to be placed in three different boxes.
Final answer:
There are 720 different permutations for filling the three positions (president, vice president, and secretary) among ten students on the student council.
Explanation:
The question asks for the number of different permutations there are for three positions (president, vice president, and secretary) among ten students on the student council.
This is a classic permutation problem in which order matters.
To calculate this, we can use the formula for permutations of 'n' items taken 'r' at a time, which is denoted as nPr and calculated as
n! / (n-r)!
where
'!' denotes factorial.
For this case, with ten students (n=10), and selecting three positions (r=3), the calculation would be:
10! / (10-3)! = 10! / 7! = 10 x 9 x 8 = 720.
Therefore, there are 720 different permutations available for the three positions on the student council.
10. Charlie biked 15 minutes home from school and then walked 12 minutes to the pizza place near his house. This trip was 3.6 miles in total. His rate on his bike is 3 miles per hour less than 5 times his walking rate. In miles per hour, what is Charlie’s speed as he walks and what is his speed as he bikes?
Answer:
3mph and 12mph
Step-by-step explanation:
GIVEN: Charlie biked [tex]15[/tex] minutes home from school and then walked [tex]12[/tex] minutes to the pizza place near his house. This trip was [tex]3.6[/tex] miles in total. His rate on his bike is [tex]3[/tex] miles per hour less than [tex]5[/tex] times his walking rate. In miles per hour.
TO FIND: Charlie’s speed as he walks and his speed as he bikes.
SOLUTION:
Let speed of charlie when he walks be [tex]x\text{ mph}[/tex]
Then speed of charlie as he biked [tex]=5x-3\text{ mph}[/tex]
Total length of trip [tex]=3.6\text{ miles}[/tex]
Total time taken[tex]=27\text{ minutes}=\frac{27}{60}\text{ hour}=\frac{9}{20}\text{hour}[/tex]
Now,
[tex]\text{Distance}=\text{speed}\times\text{time}[/tex]
distance traveled on bike [tex]=(5x-3)\times\frac{15}{60}=\frac{(5x-3)}{4}[/tex]
distance traveled by walking [tex]=x\times\frac{12}{60}=\frac{x}{5}[/tex]
As, [tex]\frac{(5x-3)}{4}+\frac{x}{5}=3.6[/tex]
[tex]\frac{29x-15}{20}=3.6\implies 29x=87[/tex]
[tex]\implies x=3\text{ mph}[/tex]
Speed of Charlie on bike [tex]=5x-3=12\text{ mph}[/tex]
Hence speed of charlie on bike and by walking is 12mph and 3mph respectively
Help me! Write an equation to describe the relationship in each table. Check out the attachment to see the tables!
Let’s look at the first table. Set up the rule: y=kx You want to replace the variables with the numbers in the chart. Let’s do 11=k21. Since y is smaller than x we would most likely use a fraction or decimal. Now what we want to do is divide 11 by 21. This should give you the result of 0.5238095238 or ≈0.52 so the rule is y=0.52x.
Now let’s look at the second chart. Let’s do 1=k4. Same thing, divide 1 by 4 which will give you the result of 0.25. The rule of this table is y=0.25x.
These equations capture the linear relationships observed in the tables, allowing you to predict the value of y for any given value of x within these patterns.
In Table 1, you can observe that as the value of x decreases by 1, the value of y also decreases by 1. This suggests a linear relationship between x and y, where y is a function of x. The equation that describes this relationship is:
[tex]\[ y = x - 10 \][/tex]
In Table 2, there is a similar linear relationship between x and y. As x decreases, y also decreases, and the change in y is consistent. The equation for this relationship is:
[tex]\[ y = \frac{x}{4} + 5 \][/tex]
In both equations, the slope is -1 in the first table and 1/4 in the second table, indicating that for each unit change in x, there is a corresponding change in y. The y-intercepts in these equations are -10 and 5, respectively, representing the values of y when x is 0.
These equations capture the linear relationships observed in the tables, allowing you to predict the value of y for any given value of x within these patterns.

What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of base of triangle BC = 45 m
The height of the triangle AB = 28 m
And , For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
On simplifying , we get
AC² = AB² + BC²
AC² = 28² + 45²
AC² = 784 + 2025
AC² = 2809
Taking square roots on both sides , we get
The measure of hypotenuse AC = √2809 = 53 m

A gardener is planting two types of trees:
Type A is 10 feet tall and grows at a rate of 21 inches per year.
Type B is 7 feet tall and grows at a rate of 25 inches per year.
Algebraically determine exactly how many years it will take for these trees to be the
same height.
9 years will take foe these trees to be the same height, If type A is 10 feet tall and grows at a rate of 21 inches per year and type B is 7 feet tall and grows at a rate of 25 inches per year.
Step-by-step explanation:
The given is,
Type A is 10 feet tall and grows at a rate of 21 inches per year
Type B is 7 feet tall and grows at a rate of 25 inches per year
Step:1
Convert the rate of grows of tree inch to feet,
For Tree A,
Rate of grow, A = 21 inches per year
= 21 × 0.0833333 ( 1 inch = 0.0833333 feet)
= 1.75 feet per year
For Tree B,
Rate of grow, B = 25 inches per year
= 25 × 0.0833333 ( 1 inch = 0.0833333 feet)
= 2.08333 feet per year
Step:2
Difference in the tall of Tree A & B,
= 10 - 7
= 3 feet
Difference in the rate of grow of tree A & B,
= 2.08333 - 1.75
= 0.3333325 feet per year
Step:3
Year take to both trees are same height,
[tex]= \frac{Difference in the height of tree A & B}{Difference in the rate of grows of A & B}[/tex]
[tex]= \frac{3}{0.3333325}[/tex]
[tex]= 9.00[/tex]
= 9 years
Step:4
Check for solution,
Height of tree = Height of Tree + (Rate of grow × Years)
For A,
= 10 + ( 1.75 × 9 )
= 25.75 feet.........................................(1)
For B,
= 7 + ( 2.08333 × 9 )
= 25.74999
≅ 25.75 feet.....................................(2)
From Equation (1) and (2),
25.75 feet = 25.75 feet
Result:
9 years will take foe these trees to be the same height, If type A is 10 feet tall and grows at a rate of 21 inches per year and type B is 7 feet tall and grows at a rate of 25 inches per year.

Given: f(x) = 3 - X; g(x) = -2x
Find g[f(x)]
Answer:
g[f(x)] = -2(3 - x) = -6 + 2x
Step-by-step explanation:
When we substitute the function f(x) for x in g(x) = -2x, we get the composition g[f(x)]:
g[f(x)] = -2(3 - x) = -6 + 2x
Final answer:
To find g[f(x)], we substitute (3 - x) from f(x) into g(x). The solution to g[f(x)] is -6 + 2x.
Explanation:
The question asks us to find the composition of the functions f(x) and g(x), specifically g[f(x)]. To do this, we first evaluate f(x) and then use that result as the input for g(x).
Given that f(x) = 3 - x, we substitute x in g(x) for the entire function f(x).
g(f(x)) = g(3 - x) since g(x) = -2x.
Now we replace the x in g(x) with (3 - x): g(3 - x) = -2(3 - x).
This simplifies to g(f(x)) = -6 + 2x.
The composition g[f(x)] is therefore -6 + 2x.

What is the surface area of the triangular prism shown below
???
Given:
Given that the base of the triangle is 4 cm.
The height of the triangle is 3 cm.
The height of the prism is 8 cm.
The other side of the triangle is 5 cm.
We need to determine the surface area of the triangular prism.
Surface area of the triangular prism:
The surface area of the triangular prism can be determined using the formula,
[tex]SA=bh+(s_1+s_2+s_3)H[/tex]
where b is the base of the triangle,
h is the height of the triangle,
s₁, s₂, s₃ are the side lengths of the triangle and
H is the height of the prism.
Substituting b = 4, h = 3, s₁ = 4, s₂ = 3, s₃ = 5 and H = 8, we get;
[tex]SA=(4)(3)+(4+3+5)(8)[/tex]
[tex]SA=12+(12)(8)[/tex]
[tex]SA=12+96[/tex]
[tex]SA=108 \ cm^2[/tex]
Thus, the surface area of the triangular prism is 108 square cm.

One of the parks mounds is 63 feet in height. If the top of the mound is rectangular in shape with a perimeter of 322 yards, what could be the side lengths of the rectangle?
Answer:
see the explanation
Step-by-step explanation:
we know that
The perimeter of rectangle is given by the formula
[tex]P=2(L+W)[/tex]
where
L is the length
W is the width
In this problem we have
[tex]P=322\ yd[/tex]
substitute
[tex]322=2(L+W)[/tex]
simplify
[tex]L+W=161\ yd[/tex]
so
The side lengths of the rectangle could be any pair of values whose sum must equal 161 yards
see the attached figure to better understand the problem
With the given height approximate the length of the rectangle
[tex]L=144\ ft[/tex]
Convert to yards
[tex]1\ yd=3\ ft[/tex]
so
[tex]144\ ft=144/3=48\ yd[/tex]
Find the width
[tex]48+W=161\\W=161-48\\W=113\ yd[/tex]
therefore
The side lengths of the rectangle could be 48 yd by 113 yd
