Answer:
Step-by-step explanation:
14x - y = -1
14x = y -1
14x +1 = y
Substitute into other problem:
3x + 2(14x +1) =13
3x + (28x + 2) = 13
31x + 2 = 13
31x = 11
x = 11/31
Answer:
5
Step-by-step explanation:
Divide 200 by 40 to get 5.
The y intercept is where the function passes through the y axis, so the “x” value needs to equal 0. We sub 0 in for “x” and solve for “y”.
f(0) = 9(0)^2 - 7 - 8(0)
f(0) = -7
Therefore the “y” coordinate would be -7
The ordered pair would be
(0, -7)
(fg)x = f(g(x)) = 6(4x+1) = 24x + 6
4*sqrt(2) * 2 * sqrt(3)
Multiply the integers together first. 4*2 = 8
Now the radicals. This is a little harder, but the question gave you one break: the numbers under the radical are prime and different, so the question is not going to break down any further.
sqrt(2) * sqrt(3) = sqrt(2*3) = sqrt(6)
So your answer is 8 sqrt(6)
