Start with which equations are written in function notation?
The only ones are the first and last, not the “y=“ ones.

Then look at the equations.
h(x) = x^2 would be a parabola, so the range wouldn’t be all real numbers. It’d only be non-negative numbers.
g(x) = 1/2 x + 3/2 would be a line. This has a range of all real numbers.

Nostrana [21]

Since 4 nights cost $356, 356÷4=89, so one night costs $89. 7-4=3, so 89×3 is 267. 267+356 is 623. The total cost for 7 nights would be $623

At the gym, Jasper was able to bench press 224 pounds, which was 7/8 of the weight that Balin was able to bench press. Which sho

Rzqust [24]

Answer:

The answer SHOULD be 7/8=224/x;256 pounds.

You may have made a mistake in inputting it here on Brainly. So look for the one that matches that.

Step-by-step explanation:

This is what we know:

Jasper = 224 pounds

Balin = x

Jasper = 7/8 of x

Now we make an equation for that:

$(\dfrac{7}{8})(x) = 224pounds$

To match the selections we will isolate 7/8 on one side of the equation:

$\dfrac{7}{8}=\dfrac{224}{x}$

Using ratio and proportion we can solve for what x is. Multiply 224 by 8 and divide it by 7. Or you can do it this way too:

$\dfrac{7}{8}=\dfrac{224}{x}$

$(7)(x)=(224pounds)(8)$

$7x=1792pounds$

$x=\dfrac{1792pounds}{7}=256pounds$

So x = 256 pounds

I got stuck on this question.<br> Use long division to solve

Phantasy [73]

Answer:

5x² +19x +76 +310/(x-4)

Step-by-step explanation:

The process is straightforward. Find the quotient term, multiply it by the divisor and subtract from the dividend to get the new dividend. Repeat until the dividend is a constant (lower-degree than the divisor).

The tricky part with this one is realizing that there is no x-term in the original dividend, so that term needs to be added with a 0 coefficient. The rather large remainder is also unexpected, but that's the way this problem unfolds.

Unlike numerical long division, polynomial long division is simplified by the fact that the quotient term is the ratio of the highest-degree terms of the dividend and divisor. Here, the first quotient term is (5x^3)/(x) = 5x^2.
