Answer:
y = 12x + 50
Step-by-step explanation:
Given,
The fixed amount of monthly allowance = $ 50,
Also, the earning per hour = $ 12,
If she works x hours in a month,
Then her total earning in x hours = 12x,
Also, total earning for a month ( say y ) = earning for x hours + fixed allowance
⇒ y = 12x + 50
Which is the required linear equation.

Miguel says that to create rectangle F' he reflected rectangle F across the y-axis, dilated the reflection by a scale factor of 3, and translated the dilated figure to the right 2 units.
What mistake did Miguel make in describing the steps of his transformation?
A. He gave the incorrect scale factor.
B. He named the incorrect axis of reflection.
C. He gave the incorrect direction of translation.
D. He gave the incorrect number of units of translation.
Answer:
A. He gave the incorrect scale factor.
Step-by-step explanation:
The scale factor is the Multiplicative Inverse of 3, which is ⅓:
F → 12 × 6
F' → 4 × 2
This is a genuine statement because according to the graph, each block is worth 2, and ⅓ of 6 is 2, and ⅓ of 12 is 4.
I am delighted to assist you anytime my friend.
Answer:
the answer is A
Step-by-step explanation:
Miguel gave an incorrect scale factor. The shape decreased in size meaning it would have a scale factor under 1 but he put 3 meaning the shape got larger when really it shrunk. This means A is the correct answer
@ 4x +(2x - 1) = x +5+x-6
Answer:
I believe the answer is 4 but im not sure because I skipped the @ but I didnt know what it meant
Step-by-step explanation:
4x +(2x - 1) = x +5+x-6
pretend that there is a 1 in front of the bracket
4x+1(2x-1)= x+5+x-6
Mutiply the bracket by 1
(1)(2x)= 2x
(1)(-1)= -1
4x+2x-1=x+x+5-6( combine like terms)
6x-1= 2x-1
move 2x to the other side
sign changes from +2x to -2x
6x-2x-1= 2x-2x-1
4x-1=-1
move -1 to the other side
4x-1+1= -1+1
4x= 0
divide by 4 for both sides to get x by itself
4x/4= 0/4
Cross out 4 and 4, divide by 4 and then becomes 1*1*x= x
x= 0/4
Answer: x= 0
write down the coordinates of the point 5 units to the left of the y axis and 3 units above the x axis
The coordinates of the point is (-5,3)
How to determine the coordinates?Let the initial coordinate be:
Initial = (0,0)
5 units to the left of the x-axis represents a horizontal translation left by 5 units.
So, we have:
New = (0 - 5,0)
3 units above the y-axis represents a vertical translation up by 3 units.
So, we have:
New = (0 - 5, 0 + 3)
Evaluate
New = (-5, 3)
Hence, the coordinates is (-5,3)

The school is taking students on a field trip. Each bus holds 32 students. If 140 students have RSVP'd, what is the fewest number of buses that can be used?
a) 5
b) 6
c) 7
Answer:
5
Step-by-step explanation:
because in 5 buses there could fit 160 students which is more than have rsvpd
Answer:
(a)
Step-by-step explanation:
Basically we're trying to figure out how many groups of 32 students are needed to have more than 140.
To do this, we take 140/32 (*BIG NOTE!! No matter what our answer is, we round up. If we rounded down, we'd be leaving some students behind, and we don't want that.)
140/32 = 4.375 (but remember, we round up no matter what)

last week at the business where you work,you sold 120 items.the business paid $1 per item and sold them for $3 each.what profit did the business make from selling the 120 items?
Answer:
The business would get 240$
Step-by-step explanation:
120$ is the amount you would of made for the the 120 items. The business gets 3$ per item. 120 x 3 would be 360, subtracted by 120 which is what they give you. The business would end up with 240$, or 2/3rds of the money.
Answer:
240
Step-by-step explanation:
since you get the items for 1 dollar and sell them for 2 you need to subtract 3-1 to get your profit which is 2. since you sold 120 items, multiply 120x2 to get your profit of 240.
A car used 1/64 of a gallon of gas to drive 1/4 of a mile. at this rate, how many miles can the car travel using 1 gallon of gas?
HELP ! SHOW WORK AND I WILL MAKE YOU THE BRAINIEST ANSWER .
Answer: 4/64
Step-by-step explanation:
Since 1/4 * 4 = 1
We just have to multiply 1/64 times 4 to get the answer
1/64 * 4 = 4/64
Answer:
Car will cover 16 miles in 1 gallon of the gas.
Step-by-step explanation:
We can solve this question by unitary method.
∵ A car used [tex]\frac{1}{64}[/tex] gallons of gas to drive the distance = [tex]\frac{1}{4}[/tex] miles
∴ Car used 1 gallons to drive the distance = [tex]\frac{\frac{1}{4} }{\frac{1}{64} }[/tex]
= [tex]\frac{64}{1}\times \frac{1}{4}[/tex]
= [tex]\frac{64}{4}[/tex]
= 16 miles
Therefore, car will cover 16 miles in 1 gallon of the gas.
The equation y-5=6(x+1) is written in point-slope form. What is the equation written in slope-intercept form?
A)y = 6x + 11
B)y = 6x – 1
C)y = 6x – 4
D)y = 6x + 6
Answer:
a. y = 6x + 11
Step-by-step explanation:
distribute and rearrange into slope-intercept form.
y - 5 = 6x + 6
add 5 to both sides
y = 6x + 6 + 5 ⇒ y = 6x + 11
Answer: Hello mate!
our equation is y - 5 = 6(x + 1), and we want to rewrite it in the slope-intercept form.
First lets distribute the parenthesis.
y - 5 = 6(x+1) = 6x + 6
now let's add 5 in both sides.
y-5 + 5 = 6x + 6 + 5
y = 6x + 11
Then the correct answer is the option A.

Answer:
17 1/2
Step-by-step explanation:
8 5/8+8 7/8=...
So, let's take away the fractions for now.
What's 8+8?
Well, 8+8=16.
Now, let's take a look at the fractions.
5/8+7/8=...
Well, when we are adding fractions, the denominator will stay the same. So let's pretend that we are adding 5+7.
5+7= 12. So our answer is 16 12/8 Right?
wrong.
you will simplify the 12/8. Since the numerator is more than eight, we will subtract 8 from 12.
12-8=4
we will make the 8/8 a 1 and add it to the 16 to make it 17 4/8. We can still simplify this. The 4/8 becomes 1/2 making the answer: 17 1/2

The medians drawn from vertex A and D are congruent.
Label medians MA and ND ; then △ABM≅△
by reason
Answer:
See explanation
Step-by-step explanation:
Given: ΔABC ≅ ΔDEF
AM, DN - medians
Prove: AM ≅ DN
Proof:
1. Congruent triangles ABC and DEF have congruent corresponding parts:
AB ≅ DE;BC ≅ EF;∠ABC ≅ ∠DEF.2. BM ≅ MC - definition of the median AM;
3. EN ≅ NF - definition of the median DN;
4. AB ≅ 2BM, EF ≅ 2EN
BM ≅ 1/2 AB,
EN ≅ 1/2 EF,
thus, BM ≅ EN
5. Consider two triangles ABM and DEN. In these triangles \:
AB ≅ DE (see 1));BM ≅ EN (see 4));∠ABM ≅ ∠DEN (see 1).So, ΔABM ≅ ΔDEN by SAS postulate.
6. Congruent triangles ABM and DEN have congruent corresponding sides BM and DN.

Find X and Y for both.
Answer:
Second picture: y=4 and x=7
First picture: x=70 degrees y=20 degrees
Step-by-step explanation:
Second picture:
One of the given triangles is an equilateral and the other is an isosceles.
Equilateral triangle has all congruent sides and it's angles are all congruent.
Isosceles triangle has two congruent angles and the opposite sides of those congruent angles are also congruent.
This implies all the side algebraic expression-measurements given are all equal.
5y-4=y+12
Add 4 on both sides:
5y=y+16
Subtract y on both sides:
4y=16
Divide both sides by 4:
y=4
So what is the side measurement for each of the sides given in terms of algebraic expressions?
y+12
4+12
16
Each side given in terms of an algebraic explanation is 16 units.
So we have also the following equation to solve:
3x-5=16
Add 5 on both sides:
3x=21
Divide both sides by 3:
x=7
So x=7 and y=4.
There is only one side in the picture that is possibly not 16. It is the one of the sides in the isosceles, not opposite the base angles.
------------------------------------------
First picture:
We are given x+y=90.
Since that one triangle is an isosceles we know that x+x+(180-40)=180
So let's solve the second equation for x then go back and solve for y in the first equation.
2x+140=180
Subtract 140 on both sides:
2x=40
Divide both sides by 2:
x=20
First equation:
x+y=90
So y=90-x=90-20=70.
if y varies direrectly as x and inversely as the square of z. y=52 when x=16 and z=2. find y when x=18 and z=3.
Answer:
y = 26
Step-by-step explanation:
Given y varies directly as x and inversely as the square of z then the equation relating them is
y = [tex]\frac{kx}{z^2}[/tex] ← k is the constant of variation
To find k use the condition y = 52, x = 16, z = 2
k = [tex]\frac{yz^2}{x}[/tex] = [tex]\frac{52(4)}{16}[/tex] = 13
y = [tex]\frac{13x}{z^2}[/tex] ← equation of variation
When x = 18 and z = 3, then
y = [tex]\frac{13(18)}{9}[/tex] = 26

good luck man i hate having to do this kind of thing in class
The formula [tex]\(A(t) = 2000(1.0075)^{4t}\)[/tex] represents the amount of money in a savings account with quarterly compounding interest over time.
The formula [tex]\(A(t) = 2000(1.0075)^{4t}\)[/tex] describes the amount of money, [tex]\(A(t)\),[/tex] in a savings account over time, where [tex]\(t\)[/tex] represents the number of years. The initial investment is $2000, and the account earns interest at a rate of 3%, compounded quarterly.
The term [tex]\((1.0075)^{4t}\)[/tex] represents the growth factor of the investment over time.
The base, [tex]\(1.0075\),[/tex] represents the factor by which the investment grows each quarter, considering the 3% annual interest rate.
Since the interest is compounded quarterly, it is raised to the power of [tex]\(4t\)[/tex] to account for the total number of quarters over [tex]\(t\)[/tex] years.
Multiplying the initial investment by this growth factor yields the total amount of money in the account after[tex]\(t\)[/tex]years.
As time increases, the exponential term increases, leading to exponential growth in the account balance.
This formula provides a mathematical model for calculating compound interest and understanding how investments grow over time.

Where x is the number that we don't know.
Now it says that that product is 6 more than the number (x) so we can write it down:
3x (The product of a number and 3) = (is) 6 + x (6 more than the number)
3x = 6 + x
The sentence 'the product of a number and 3 is 6 more than the number' can be translated into the algebraic equation 3x = x + 6.
Explanation:The given statement can be translated into a mathematical equation in the following way: If we let x be the number in question, the first part of the sentence tells us that the product of the number and 3 can be modeled as 3x. The second part of the sentence tells us that this is 6 more than the number itself. This can be translated into the equation as x + 6. Thus, putting the two parts together, we get the algebraic equation 3x = x + 6.
