Answer:

$\sqrt[3]{7}$

Step-by-step explanation:

$here \: the \: power \: of \: 7 \: is \: 3 \\ the \: cube \: represented \: by \: the \: radical \: sign \: with \: number \: 3 \\ \sqrt[3]{x} =cube \: root \: . \\ so \: we \: can \: write \: the \: given \: expression \ \: as \: \\ \: 7 \times \frac{1}{3} = \sqrt[3]{7} \\ thus \: \: the \: ans \: is \: a. \: \sqrt[3]{7}$

lora16 [44]

Answer:

500

Step-by-step explanation:

Given: P = 150 - T where P is passenger cars and T is trucks

10P = 7T ⇔ P = $\frac{7T}{10}$

Plug in equation 2 into equation 1:

$\frac{7T}{10}$ = 150 - T

Solving for T, we get 500

Kapil needed to buy a long wooden beam. He went to two sawmills that each charge an initial fee plus an additional fee for each

matrenka [14]

Answer: first sawmill charges more for each meter of wood. And first mill has a cheaper price for 5-meter wooden beam.

Step-by-step explanation:

P=5+20x. The first sawmill charges $20. Then 110-20/5-0=18 Which means The second sawmill charges $18 for each meter of wood. Since 20>18 The first sawmill charges more for each meter of wood.

P = 5+20x

=5+20x•5

= 105

The first mill charges $105 For a 5 meter beam while the second beam charges $110

Which phrase best descubes the translation from the graph y = (x - 5)2 + 7 to the graph of y = (x + 1)2 - 2?

Ber [7]

Answer:

"6 units left and 9 units down"

Step-by-step explanation:

Suppose a function is given in this form:

$y=(x-a)^2+b$

This is the parent function y = x^2

translated a units right (left if there was a + before a)
translated b units up (down if there was a - before b)

Now, to go from $y=(x-5)^2+7$ to $y= (x+1)^2-2$ , we can see that:

first function is 5 units right and 2nd one is 1 unit left, so there is a horizontal translation of 6 units left
first function is 7 units above and 2nd one is 2 units down, so there is a vertical translation of 9 units down

Thus, "6 units left and 9 units down" is the transformation(translation).
