The answer is A because the slope is 25 and y intercept is 100.

If F(x) and G(x) are two functions such that F(G(x)) = x then F(x) and G(x) are ..?

lana [24]

They are inverse functions though to be completely thorough your teacher should have also put g(f(x)) = x as well. Though I can see what your teacher is aiming for at least.

The idea is that whatever the output of g(x) is, it's plugged into f(x) and the initial input is the result. So g(x) takes a step forward and f(x) takes a step back undoing everything g(x) did. Which is exactly what an inverse operation does.

What are the diameters of the painting? Easy!!!

x = 10.22 in

Solution:

Width of the figure = x in

Length of the figure = (2x + 5) in

Area of the figure = 260 in²

To find the value of x:

Area of the figure = length × width

length × width = 260

(2x + 5) × x = 260

$2x^2+5x=260$

Subtract 260 from both sides of the equation.

$2x^2+5x-260=0$

Factor the above quadratic expression.

Quadratic equation formula:

$$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

$$x=\frac{-5 \pm \sqrt{5^{2}-4 \cdot 2(-260)}}{2 \cdot 2}$

$$x=\frac{-5 \pm \sqrt{2105}}{4}$

$$x=\frac{-5+\sqrt{2105}}{4}, \ x=\frac{-5-\sqrt{2105}}{4}$

x = 10.22, x = –12.72006

Dimension of the figure cannot be measured in negative terms.

Hence x = 10.22 in.

If you assume the samples are representative how many whole wheat bagels might you infer are sold at each store

Alexxandr [17]

Maurine owns three bagel shops. Each shop sells 500 bagels per day. Maureen asks her store managers to use a random sample to see how many whole wheat bagels are sold at each store each day. Shop A has total of 50 bagels in sample and 10 are whole wheat bagels. Store B has a total of 100 bagels in sample and 23 are whole wheat bagels. Shop C has 25 total bagels in sample and 7 are whole wheat bagels.

We find fraction of whole wheat bagels to the sample for each shop using given information

Shop A = $\frac{10}{50} = 0.20$
