-BARSIC- [3]3 years ago
6 0

Set up a proportion: x/y = x/y

(.75)/(15) = (x)/(25)

Then cross multiply:

(.75)(25) = (15)(x)

18.75 = 15x

x = 1.25 or (5/4)

There you go :)

If y=3x+4 we're changed to y=5x+4 how would the graph of the new function compare to the first one
dusya [7]

Answer:

A. It would be steeper

Step-by-step explanation:

In the linear equation y = mx + b, m is the slope and b is the y intercept.

In this problem, the function is changed to have a larger slope of 5, compared to the original slope of 3. But, the y intercept stays the same.

Since the y intercept remained the same, it will not be shifted in any direction.

But, with a larger slope, the graph will be steeper.

So, the correct answer is A. It would be steeper

3.

3x + 3x + x + x = 16

16 = 8x

x=2

Width is 2

4.

5 - 3 = 2

Check all of the ordered pairs that satisfy the equation below.
stiv31 [10]

Answer:

Hey there!

y=3/4x shows that the y-value is always 3/4 of the x-value.

Thus, if x is 4, y is 3. It always fits the 4:3 ratio.

The ordered pairs that satisfy this equation are: 28:21 and 16:12

Let me know if this helps :)

If f(x) = x2, which of the following describes the graph of f(x) - 5? A)The graph of f(x) - 5 is a vertical shift of f(x) = x2 f
lana [24]
F(x) = x^2 is a parabola with vertex at the origin (0,0).
f(x) = x^2 - 5 is a parabola shifted down 5 units so it's vertex would be at (0, -5)
The correct answer is Letter B
