Answer:

the square root of 2(x^3 * x^2)

Step-by-step explanation:

twice means 2 and product means either division or multiplication (multiplication in this scenario because twice means multiply). cubed means to the third power

note i don't know how to put a square root sign so i wrote it out

hope i helped

I need help understanding this ASAP plz, I have a quiz over this next week!!!!

Answer:

Step-by-step explanation:

With any two points, you can find the line between them with:

$y = mx + b\\where\\m = \frac{y_2-y_1}{x_2-x_1}$

#1:

(-1, 1) -> (1, 3) $m = \frac{3-1}{1-(-1)} = 1, 3 = 1(1) + b, b = 2, y = x + 2$

(3, 4) -> (0, 2) $m = \frac{4-2}{3-0} = \frac{2}{3}, 2 = \frac{2}{3}(0) + b, y = \frac{2}{3}(x)+2$

(0, 1) -> (3, 3) $m = \frac{3-1}{3-0} = \frac{2}{3}, 1 = 2/3(0) + b, y = \frac{2}{3}(x) + 1$

Lines b and c are parallel because they have the same slopes

#2 is a bit easier

a: 2y = x + 12, $y = \frac{1}{2}(x) + 6$

b:2y - x = 5, $y = \frac{1}{2}(x) + \frac{5}{2}$

c: 2y + x = 4, $y = \frac{-1}{2}(x) + 2$

Since lines a and b have the same slope, they are parallel

#3:

(1, 3), y = 2x - 5

We have to find a line with a slope of 2 that passes through the two points

$y = 2x + b\\3 = 2(1) + b\\b = 1\\\\y = 2x + 1$

#4:

(-2, 1) , y = -4x + 3

We have to find a line with a slope of-4 that passes through the line

$y = -4x + b\\1 = -4(-2) + b\\1 = 8+ b\\b = -7\\y = -4x - 7$

#5:

(-2, 3) (1, -1), $m = \frac{3-(-1)}{-2-1} = \frac{-4}{3}, 3 = \frac{8}{3} + b, b = \frac{1}{3}, y = \frac{-4x}{3} + \frac{1}{3}$

(-3, 1) (1, 4), $m = \frac{4-1}{1-(-3)} =\frac{3}{4}, 4 = \frac{3(1)}{4} + b, y = \frac{3}{4}(x) + \frac{13}{4}$

(0, 2) (3, -2) $m = \frac{2-(-2)}{0-3} = \frac{-4}{3} , 2 = b, y = \frac{-4}{3}(x) + 2$

Since lines c and b have negative reciprocal slopes, they are perpendicular

#6:

a: y = -4x + 7

b: x = 4y + 2, $y = \frac{x}{4} - \frac{1}{2}$

c: -4y + x = 3, $y = \frac{x}{4} - \frac{3}{4}$

since lines a and c have negative reciprocal slopes, they are perpendicular

This is a slope intercept form problem...can anybody please help me thank you ♥️

spayn [35]

Hi There!

-----------------------------------------

We Know:

$35 per person.

Guides Fee: 10 * 35 = 350

425 - 350 = $75 (guide fee)

-----------------------------------------

Part A:

The problem states to put c as cost and p as number of people:

c = 35p + 75

b = $75 (guide fee)

If you don't need the one above, this is just in slope intercept form.

y = 35x + 75

b = $75 (guide fee)

Answer: c = 35p + 75 or y = 35x + 75

-----------------------------------------

Part B:

How much would it cost for 15 people?

Lets use: c = 35p + b

Substitute p for 15 people and b as $75 for the guide fee: c = 35(15) + 75

Simplify: c = $600

Answer: The total cost for 15 people is $600.

-----------------------------------------

Hope This Helps :)

Determine where f(x) = x2 + 2x - 8 intersects the x-axis.

V125BC [204]

Let f(x) =0.
${x}^{2} + 2x - 8 = 0 \\ (x + 4)(x - 2) = 0 \\ x + 4 = 0 \\ x = - 4 \\ x - 2 = 0 \\ x = 2$
x=-4, 2
