since 3/4 or 75% ARE black, 1/4 will not be black. 1/4=.25 which is 25%.

Answer:

Step-by-step explanation:

Hi!

First we need to translate 2 units down. That means we need to subtract 2 from the y value. So now we have (-1,1).

For a 270 degree counterclockwise rotation the rule is to go from (x,y) to (y,-x)

So now we have (1,1). Since they're only asking for the x value, the answer is 1.

Amy had homework for math, science, and history she spent 1/3

Nastasia [14]

First, we have to convert the fractions so that they have common denominators.

Now we add the fractions together.

Now, to find the fraction of the time that Amy spent on history, we need to subtract the sum of the time she spent in math and science from one whole.

Amy spent 5/12 of her time working on history.

Write the equation of the line that passes through the points (3,5)(3,5) and (6,7)(6,7). Put your answer in fully simplified poi

nika2105 [10]

The equation of the line will be y = ( 2 / 3 ) x + 3.

<h3>What is an equation of the line?</h3>

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

Given that the equation of the line that passes through the points (3,5) and (6,7).

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

First, calculate the slope of the line:-

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 7 - 5 ) / ( 6 - 3 )

Slope = ( 2 / 3 )

The y-intercept will be calculated as follows:-

y = mx + c

5 = ( 2 / 3 ) x 3 + c

5 = 2 + c

c = 3

The equation of the line will be calculated as;-

y = mx + c

y = ( 2 / 3)x + 3

Therefore, the equation of the line will be y = ( 2 / 3 ) x + 3.

Please please help!!!! I will give brainliest!!!!! Use the remainder theorem to find the remainder of 2x^4 + x^2 - 10x -1 divide

natka813 [3]

Given:

$p(x)=2x^4+x^2-10x-1$ divided by $x+2$

To find:

The remainder.

Solution:

$p(x)=2x^4+x^2-10x-1$ divided by $x+2$

<u>Remainder theorem:</u>

<em>If a polynomial p(x) is divide by x - a, then the remainder is p(a).</em>

$x+2=0$

Subtract 2 from both sides, we get

$x=-2$

substitute x = -2 in p(x).

$p(-2)=2(-2)^4+(-2)^2-10(-2)-1$

$=2(16)+(4)+20-1$

$=32+4+19$

$=55$

The remainder is 55.

Find the inverse, picture below!

Setler79 [48]

Answer:

$f^{-1}(x) = (x+7)^2$

Step-by-step explanation:

$y=f(x) = \sqrt x - 7 \\\\\text{Replace x with y and then solve for y:}\\\\~~~~~~~~x= \sqrt y -7\\\\\implies \sqrt y = x+7\\\\\implies y = (x+7)^2\\\\\implies f^{-1}(x) = (x+7)^2$
