The image of X after the dilation is (a) (4, 0)

<h3>How to determine the image of X?</h3>

From the figure, the coordinates of X are given as:

X = (4, 0)

The dilation is given as:

Do,1

This means that we dilate X across the origin by a scale factor of 1.

So, we have:

X' = 1 * (4 - 0, 0 - 0)

Evaluate

X' = (4, 0)

Hence, the image of X after the dilation is (a) (4, 0)

H(a) = 2a+ 5g(a) = 3a−5Find h(a)+ g(a)

Alexandra [31]

Answer:

Step-by-step explanation:

h(a) = 2a+ 5

g(a) = 3a−5

h(a)+g(a)

(2a+5)+(3a-5) (substitution)

2a+5+3a-5 (open parentheses)

5a+0 (solve)

The sum of two numbers is 79,and their difference is 33

DerKrebs [107]

Answer: infinite answers, jk there is like a lot tho

Step-by-step explanation: The sum of x and y is 79. In other words, x plus y equals 79 and can be written as equation A:

x + y = 79

The difference between x and y is 23. In other words, x minus y equals 23 and can be written as equation B:

x - y = 23

Now solve equation B for x to get the revised equation B:

x - y = 23

x = 23 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 79

23 + y + y = 79

23 + 2y = 79

2y = 56

y = 28

Now we know y is 28. Which means that we can substitute y for 28 in equation A and solve for x:

x + y = 79

x + 28 = 79

X = 51

Summary: The sum of the two numbers is 79 and their difference is 23. What are the two numbers? Answer: 51 and 28 as proven here:

Sum: 51 + 28 = 79

Difference: 51 - 28 = 23

How many gallons of a 70% antifreeze solution must be mixed with 60 gallons of 20% antifreeze to get a mixture that is 60% a

Flura [38]

We have 60 gallons of 20% antifreeze.

How much 70% antifreeze do we add to get 60% antifreeze?

We'll make "x" the gallons of 70% we must add.

.20 * 60 + .70 x = .60 * (60 + x)

12 + .70x = 36 + .60x

.10x = 24

x = 240 gallons of 70% antifreeze.
