The answer is: 45 .
________________________________
3/5 * 75 = 3/5 * 75/1 ;
The "5" cancels to a "1"; and the "75" cancels to a "15" ;
since "75÷5 = 15" ; and since "5÷5 =1" .
So, rewrite the problem:
3/1 = 15/1 = 45/1 = 45.

3/5 * 75 = 6/10 * 75 = 0.6 * 75 = 45.0 = 45 .

X^2+ 7x + 16 =0 I think this will be the answer.
Answer:
X-intercept = -3 and y-intercept = 6
Step-by-step explanation:
We can start off by isolating the y term. To do that, we must add 2y to both sides to get
![4x=2y-12](https://tex.z-dn.net/?f=4x%3D2y-12)
Now, we must add 12 to both sides and the y term will be all alone on the right side:
![4x+12=2y](https://tex.z-dn.net/?f=4x%2B12%3D2y)
Now, to have only y on the right side, we must divide by 2 to get:
![y=2x+6](https://tex.z-dn.net/?f=y%3D2x%2B6)
In slope-intercept form, b is the y-intercept, and 'b' in this equation is 6. We have our y-intercept.
To find our x-intercept, y must be equal to zero. We can plug in that value for y and solve for x:
![0=2x+6](https://tex.z-dn.net/?f=0%3D2x%2B6)
We can start off by subtracting 6 from both sides to get:
![2x=-6](https://tex.z-dn.net/?f=2x%3D-6)
We can then divide both sides to get
when y is equal to 0. Thus, we have our x-intercept.
Hello,
f(x)-2x-7
g(x)=-4x+3
(fog)(x)=f(g(x))=f(-4x+3)=-2(-4x+3)-7=8x-6-7=8x-13
(fog)(-5)=8*(-5)-13=-53
Answer:
5
Step-by-step explanation: i think its right but you need to add the 5 and 7, and i divided it by the amount total, :)
