Answer:
to solve this you need to find out what number n is to make it equal 28.
Step-by-step explanation:
19+3 =22 so 3 is not it
19+9=28
answer is 9
hopefully this is right and this gets to you on time
Answer:
30 is 120% of 25
Step-by-step explanation:
30 = 120% of y
× y = 30
After multiplying both sides by 100 and dividing both sides by 120, we have
y = 30 × 
y = 25
Answer:
31.5 units²
Step-by-step explanation:
Area = ½*base*height
Height of the triangle on the grid = 9 units
Base = 7 units
Area = ½*9*7
Area = ½*63
Area = 63/2
Area = 31.5 units²
Answer:
See explanation below.
Step-by-step explanation:
Let's assume that we have an original function
and let's suppose that we have a constant
and if we define this new function:

We see that if c>1 the dunction would be vertically stretched by c units.
And if
we see that we will have a vertically shrinking by a factor of c units
So for example we can use the following function:

For this case our constant is c=0.75 and we can define the new function like this:

We will see if we plot the two figures that we have a vertical shrinking of 0.75 units.
