what is a..
Positive slope?
Negative slope?
Undefined slope?
Zero slope?
Please explain all in a good and understandable way and thank you
Answer:
Positive Slope-A positive slope means that two variables are positively related—that is, when x increases, so does y, and when x decreases, y decreases also. Graphically, a positive slope means that as a line on the line graph moves from left to right, the line rises. Another words, the line goes up.
Negative Slope-A line with a negative slope is a line that is trending downward from left to right. In other words, the line's rise to run ratio is a negative value. Or the line goes down
Undefined Slope- An undefined slope is the slope of a vertical line! The x-coordinate never changes no matter what the y-coordinate is.
Zero Slope-A zero slope is just the slope of a horizontal line. The y-coordinate never changes no matter what the x-coordinate is.

Solve 2y+1−x=7x for y
Answer:
Y=4X-1/2
Step-by-step explanation:
You must isolate the variable by dividing each side by factors that dont contain variables.
Answer:
y = 4x - 1/2
Step-by-step explanation:
2y + 1 − x = 7x
2y = 7x + x - 1
2y = 8x - 1
y = (8x - 1)/2

If the sphere has a volume of approximately 904.78 cm3, what is the approximate area of the largest cross-section of the sphere shown? A) 28.27 cm2 B) 113.1 cm2 C) 226.2 cm2 D) 452.39 cm
Final answer:
Given a sphere with a volume of 904.78 cm3, we find the radius to be approximately 6.13 cm, and the area of the largest cross-section, a circle, turns out to be approximately 118.08 cm2.
Explanation:
If the sphere has a volume of approximately 904.78 cm3, we can start by calculating the radius of the sphere using the volume formula for a sphere:
V = (4/3)πr3
Solving for r:
r = &Sqrt[3]{(3V)/(4π)} = &Sqrt[3]{(3×904.78 cm3)/(4π)} ≈ 6.13 cm
The largest cross-section of the sphere will be a circle with the diameter equal to the diameter of the sphere, hence the area A of this circle will be:
A = πr2 = π×(6.13 cm)2 ≈ 118.08 cm2
Therefore, the approximate area of the largest cross-section of the sphere is 118.08 cm2, which is not listed among the provided options, implying a possible typo or error in the options. Option closest to the calculated area is B) 113.1 cm2.

Choices:
(A) 5.6
(B) 8.75
(C) 11
(D) 15
Answer:
TS = 11.
Step-by-step explanation:
Consider triangles UTO and UCS.
m < C = m < UTO (Given)
< U is common to both triangles.
Therefore triangles UTO and OCS are similar.
So corresponding sides are in the same ratio and:
5 / (TS + 4) = 4/ (7+5)
5 * (7 + 5) = 4(TS + 4)
TS + 4 = 5*12 / 4
TS + 4 = 15
TS = 11.

-6 = x/8 + 4
Answer:
-80
Step-by-step explanation:
We have: -6 = [tex]\frac{x}{8}[/tex] + 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.
The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.
Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:
-6 - 4 = [tex]\frac{x}{8}[/tex] + 4 - 4 ⇒ -10 = [tex]\frac{x}{8}[/tex]
Then, multiply by 8 on both sides:
-10 * 8 = [tex]\frac{x}{8}[/tex] * 8 ⇒ x = -80
Thus, x = -80.
Hope this helps!
Answer:
x = -80
Step-by-step explanation:
Alright let's get started!
Rewrite the equation as ,
x/8 + 4 = -6
Move all terms not containing x to the right side of the equation.
(Subtract 4 from both sides of the equation.)
x/8 = -10
Multiply both sides of the equation by 8 to get rid of the denominator,
8 * x/8 = -10 * 8
8 cancels out on the left side,
x = -80
y = 2x + 5 for x = 1.
1. ( 1, 12)
2. (1, -2 )
3. ( 3, 1 )
4. ( 1, 7 )
Since you know the value of x, you can substitute/plug it into the equation to find the value of y:
y = 2x + 5 Plug in 1 into "x" since x = 1
y = 2(1) + 5
y = 7
When x = 1, y = 7 --> (x, y) = (1, 7) Your answer is #4
A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 85% pure antifreeze. The company wants to obtain 255 gallons of a mixture that contains 60% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?
Answer:
75 gallons of water
180 gallons of premium anti-freeze
Step-by-step explanation:
X + Y = 255
X = 255 - Y
0.85Y = 0.6(255)
0.85Y = 153
Y = 180
X = 255 - 180
X = 75
Name the quadrant in which the point (–4, –4) lies. III IV II I
Which of these defines the longest arc?
Answer: C
Step-by-step explanation:
The arc length, s, equals the radius, r, times the central angle, θ, given in radians. (In shorthand, s=r⋅θ.) If r=5 cm and θ=6 radians, the arc length is 5 cm⋅6=30 cm. If r=7 cm and θ=5 radians, the arc length is 7 cm⋅5=35 cm. If r=9 cm and θ=4 radians, the arc length is 9 cm⋅4=36 cm. An angle of 180∘ is π radians, or about 3.14. If r=10 cm, the arc length is 10 cm⋅3.14=31.4 cm. Of these choices, the longest arc is 36 cm.
If [tex]\sqrt{5}[/tex] = x - 2, what is the value of (x - 2)[tex]^{2}[/tex]?
Answer:
5 = (x - 2)^2
Step-by-step explanation:
sqrt(5) = x - 2
Square each side
(sqrt(5))^2 = (x - 2)^2
5 = (x - 2)^2
Okay this is easier than you think!
if (x - 2) equals [tex]\sqrt{5}[/tex]
then that means [tex](x-2)^{2}[/tex] = [tex]\sqrt{5} ^ {2}[/tex]
Anything under a square root when sqared, is itself
[tex]\sqrt{5} ^{2} = 5[/tex]
so the value of [tex](x-2)^{2}[/tex] = 5

What is the volume of this container?
Answer:
504 in³
Step-by-step explanation:
this is a rectangular prism and the volume formula is v = l * h * w
so now
v = l*w*h
v= 6*8*12
v = 576 inch³
that's not the answer, that's the volume for whole thing but there is a gap and we have to subtract it from the whole volume. you can look at the option and say it's 504 inch³ from common sense. here is the work:
the gap has 2 inch length, 6 inch width and 6 in height.
v = l*h*w
v = 6 * 2 * 6
v= 72 inch
now subtract the gap volume from total volume so
576 - 72 = 504 in³

8. If mLM = (8x - 56) and mNP = (5x + 22),
find mLP.
M 39°N
LP
Based on the calculations, the measure of arc LP is equal to 17°.
In Mathematics and Geometry, a perpendicular bisector is a segment, or ray that bisects a line segment exactly into two (2) equal halves and forms an angle that has a magnitude of 90 degrees at the point of intersection.
Based on the definition of a perpendicular bisector, we can logically deduce that the two larger arcs have the same measure;
mLM = mNP
8x - 56 = 5x + 22
8x - 5x = 22 + 56
3x = 78
x = 78/3
x = 26°
Since the sum of all the four (4) arcs form a full circle, we would set up an equation and equate it to 360 degrees;
mLM + mNP + mMN + mLP = 360°
8x - 56 + 5x + 22 + 39 + mLP = 360°
8(26) - 56 + 5(26) + 22 + 39 + mLP = 360°
152 + 152 + 39 + mLP = 360
mLP = 360 - 343
mLP = 17°

a basketball player attempted 15 baskets in the game he makes 9 of the attempted baskets which ratio describes the number of baskets the player made to the number of baskets to play attempted thanks so much!!
Answer:
3:5
Step-by-step explanation:
We are given that
Basket player attempted basket=15
He makes number of attempted basket=9
We have to find the ratio which describes the number of baskets the player made to the number of baskets to play attempted.
[tex]\frac{number\;of\;baskets\;made}{number\;of\;basket\; to play attempted}=\frac{9}{15}[/tex]
[tex]\frac{number\;of\;baskets\;made}{number\;of\;basket\; to play attempted}=\frac{3}{5}[/tex]
