To find the slope use the formula Y2-Y1 --------- X2-X1 (-1,-4) (1,4) 4- -4 = 8 ------------- 1- -1 = 2 8/2=4 This will be your slope Y=4x Now we must figure out the y-intercept using the formula Y-y1=slope(x-x1) Y- -4= 4(x- -1) Y+4= 4x + 4 The 4 distributes to the x and -1 Y=4x +4 -4 Y= 4x This is your answer in slope intercept form. P.S if you have a number minus a negative number it makes it a positive number

The following triangles are similar. Find side AB.

tankabanditka [31]

Answer:

Step-by-step explanation:

Set up ratios of corresponding sides. x+2 is to 6 as 2 is to 3:

$\frac{x+2}{6}=\frac{2}{3}$

Now cross multiply to get

3(x + 2) = 12 and

3x + 6 = 12 so

3x = 6 and

x = 2. That means that side AB, x + 2, is 2 + 2 which is 4

2. Find the volume of the prism. Round to the nearest tenth.

$\huge\mathcal\pink{ANSWER}$

$\mathsf \purple{ v = \frac{1}{2} (a + b) \times h \times l}$

$\mathsf \pink{v = \frac{1}{2} (5 + 12) \times 6.1 \times 16}$

$\mathsf \purple{v = \frac{1}{2} (17) \times 6.1 \times 16}$

$\mathsf \pink{v = 8 \frac{1}{2} \times 6.1 \times 16}$

$\mathsf \purple{v = 829.6 {mi}^{3} }$

Simplify. (2/5)^4... words to fill in minimum space

Stella [2.4K]

When you have a power to a fraction, you simply take it by the top and then by the bottm.

So, split it into two: (2)^4 and (5)^4

Solve: (2)^4=16
(5)^4=625

So the fraction is: 16/625

Check to see if it reduces: It doesn't. (Odd and even numbers that have no common multiples).

Therefore, that's the answer.
