2x+2y= 24<br> x=3y<br> What is the value of x+y? I WILL MARK BRAINLIEST AND GIVE 20 POINTS.

Ivanshal [37]

Since this is a system of equations, substitute the value of x into the other equation.

2(3y)+2y=24
6y+2y=24
8y=24
y=3

x=3(3)
x=9

To check my work, substitute my x and y values:
2(9)+2(3)=24
18+6=24
24=24

Your answer is (3,9)

Hope this helps! Have a wonderful day :)

If 2/3 inch on a map corresponds to an actual distance of 9 miles what distance on the map will represent 21 miles

weeeeeb [17]

2/3in=9mi
?in=21mi

we can set up a ratio and proportion, but I would fix that fractions because they tend to be messy

2/3in=9mi
multiply both sides by 3
2in=27mi

so now we have
2in:28mi=?in:21mi
$\frac{2in}{28mi}=\frac{?in}{21mi}$
multiply both sides by 21mi
the miles cancel and we get
$\frac{42in}{28}=?in$
1.5in=?in

1.5 inches represents 21 miles

Describe how the graph of y= x^2 can be transformed to the graph of the given equation.

7nadin3 [17]

Answer:

Step-by-step explanation:

Given y = x² then y = x² + c is a vertical translation of y = x²

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here c = - 12 < 0

Thus y = x² - 12 is the graph of y = x² shifted 12 units down → b
