Answer:
1. y= 10 2.y= -10 3.y= 6 4.y= -2
Step-by-step explanation:
You basically just replace x with the number.
So, for y = 4 + 2x, then replace x with 3 and go y = 4 + 2(3)
which translates to y = 4 + 6 which equals 10
Answer:
10, - 10, 6, - 2
Step-by-step explanation:
Substitute each given value of x into the expression and evaluate.
x = 3 → y = 4 + 2(3) = 4 + 6 = 10
x = - 7 → y = 4 + 2(- 7) = 4 - 14 = - 10
x = 1 → y = 4 + 2(1) = 4 + 2 = 6
x = - 3 → y = 4 + 2(- 3) = 4 - 6 = - 2

which equation is perpendicular to the graph of 5x - 3y = 12
Answer:
y = -3/5x + c
Step-by-step explanation:
Re-arrange the initial equation so that the it becomes y =
To do this, you +3y on both sides to get 5x = 3y + 12
And then -12 on both sides to get 5x - 12 = 3y
Divide everything by 3 so you get 5/3x - 4 = y OR y = 5/3x - 4
The gradient of the initial equation is 5/3, to find the perpendicular line, you need the negative reciprocal of it, which is -3/5
Therefore your perpendicular line should be y = -3/5x + c
Because you didn't specify on what point they intersect, i can't find c for you.
Lisa gets paid $28 to babysit her little brother for 4 hours. At this rate, how much will she earn if she babysits her brother for 16 hours.
Answer:
$112
Step by step explanation:
Show your reasoning.
2y=x-4
4x + 3y = 5
PLS HELP
Answer:
(2,-1)
divide both sides of the first equation by 2 to get y by itself. this gets you y=x/2-2
then plug that into the other equation:
4x+3(x/2-2)=5
SImplify that to get:
4x+3x/2-6=5
Add 6 to both sides:
4x+3x/2=11
give 4x a denominator of 2 as well:
8x/2+3x/2=11
add them:
11x/2=11
multiply both sides by 2/11 to get:
x=22/11 which simplifies to x=2
plug x into first equation:
2y=(2)-4
simplify:
2y=-2
divide both sides by 2 to get:
y=-2/2 which is the same as -1
x=2
y=-1
answer: (2,-1)

To find the volume of a rectangular prism, you can use the formula of V = l w h. A rectangular prism has a volume of 60 cubic centimeters, a height of 3 cm, and a length of 5 cm. What is the width of the prism?
Answer:
W = 4
Step-by-step explanation:
The nice thing about algebra is that you can look for any variable in an equation as long as you have the number for the other variables.
1. Write our the equation. V = l w h
2. Put in as many numbers as you can. 60 = 5 w 3
3. Isolate the variable. To do that perform the mathematical opposite to the target on both sides. So to get rid of five, we have to divide it on both sides of the equal sign.
60/5 = w 3
12/3 = w
4 = w
The width is 4cm
gross pay $23760 married with 3 dependents state income tax rate 4%
Answer:
950.40
Step-by-step explanation:
The annual amount withheld for state tax would be $950.40.
Given that, gross pay $23760 married with 3 dependents state income tax rate 4%,
We need to calculate, amount withheld annually for state tax.
To calculate the annual amount withheld for state tax, we need to multiply the gross pay by the state income tax rate.
Here's the calculation:
Annual state tax withheld = Gross pay x State income tax rate
Gross pay = $23,760
State income tax rate = 4% (0.04)
Annual state tax withheld = $23,760 x 0.04 = $950.40
Therefore, the annual amount withheld for state tax would be $950.40.

Which is the greater rate, 22 miles in 20 minutes or 38 miles in 30 minutes?
Answer:
38 miles in 30 minutes
Step-by-step explanation:
To answer the question, we first want to find a common multiple of both numbers. The nearest is 60. Multiply each minute number to get to 60, multiply their other number by the same amount.
So, the first rate will travel 66 miles in 60 minutes while the second rate will travel 76 miles in 60 minutes. Therefore, the answer is the second option, 38 miles in 30 minutes.
Hope this helps! Let me know.
The greater rate is, ''38 miles in 30 minutes.''
What is ratio?The ratio is a numerical relationship between two values that demonstrates how frequently one value contains or is contained within another.
We have two rates:
22 miles in 20 minutes,
and 38 miles in 30 minutes.
The ratio of rate:
22/20 = 1.1
38/30 = 1.27
Therefore, the rate = 38 miles in 30 minutes is greater.

MARK YOU BRAINLIST It takes Pervis 20 minutes to ride his bicycle 1.5 miles to school each day. How far can Pervis ride in one hour if he continues to travel at this speed?
A. 4.5 miles
B. 7.50 miles
C. 0.4 miles
D. 5.625 miles
Answer:
4.5 miles
Step-by-step explanation:
so basically 1 hour equals 60 minutes so we divide 60 by 20 because he can ride 1.5 miles in 20 minutes. so 60/20 is 3 and now all we do is multiply 1.5 by 3 which gives us 4.5.

The figure is made from squares of different sizes.Find the area of A if the side of each of the two indentical smallest square is 2cm.
Answer:
The area of square A is 256 cm²
Step-by-step explanation:
The four sides of a square are equal in lengthArea of a square = side × sideIn the given figure
∵ The sides of the square E = 2 cm each
∵ The sides of the square F = 2 cm each
∵ The side of square D is the sum of the sides of squares E and F
∴ The sides of the square D = 2 + 2 = 4 cm each
∵ The side of square C is the sum of the sides of squares E and D
∴ The sides of square C = 2 + 4 = 6 cm each
∵ The side of square B is the sum of the sides of squares C, E, and F
∴ The sides of square B = 6 + 2 + 2= 10 cm each
∵ The side of square A is the sum of the sides of squares B, F, and D
∴ The sides of square A = 10 + 2 + 4= 16 cm each
∵ Area of square A = side × side
∴ Area of square A = 16 × 16
∴ Area of square A = 256 cm²
∴ The area of square A is 256 cm²

Step-by-step explanation:
if f(x)=2x+5, g(x)=x², h(x)= -2x
h(g(f(x))) = h(g(2x+5)) = h((2x+5)²) = h(4x²+20x+25) = -2(4x²+20x+25)

In New Salem North Dakota there is a 38-ft-tall statue of a cow named Salem Sue. Suppose the statue's shadow was 57 feet long and a 3.5 foot child was standing next to the statue. How long would the child statue be?
Answer:
5.25 feets
Step-by-step explanation:
Given that:
Height of Salem Sue = 38 feets
Height of Salem Sue's shadow = 57 feets long
Height of child standing next to the statue = 3.5 foot tall
Length of the child's shadow =?
Let lenght of child's shadow = s
IF;
38 Feets tall = 57 feets lenght
3.5 feets tall = s feets long
Cross multiply :
38 * s = 57 * 3.5
38s = 199.5
38s / 38 = 199.5 /38
s = 5.25
Hence, length of the child's shadow will be 5.25 feets long
