Answer:

58

Step-by-step explanation:

We are given the arithmetic sequence:-

-12,-7,-2,3,...

First, find the common difference which we can obtain by:-

\displaystyle \large{d = a_{n + 1} - a_n}

Check:-

-7-(-12) = -7+12 = 5

-2+7 = 5

3+2 = 5

Therefore, our common difference is 5.

<u>G</u><u>e</u><u>n</u><u>e</u><u>r</u><u>a</u><u>l</u><u> </u><u>A</u><u>r</u><u>i</u><u>t</u><u>h</u><u>m</u><u>e</u><u>t</u><u>i</u><u>c</u><u> </u><u>T</u><u>e</u><u>r</u><u>m</u>

\displaystyle \large{a_n = a_1 + (n - 1)d}

Since we want to find the 15th term, substitute a1 = -12, n = 15 and d = 5.

\displaystyle \large{a_{15}=  - 12 + (15 - 1)5} \\  \displaystyle \large{a_{15}=  - 12 + (14)5} \\  \displaystyle \large{a_{15}=  - 12 + 70} \\  \displaystyle \large{a_{15}= 58} \\

WILL GIVE BRAINLIEST graph -8=2x-y using the x and y intercepts (show your work pls)
Ahat [919]

Answer:

-8=2x-y get this into y=mx+b form to find the y-intercept

-y=-2x-8

y=2x+8

the y-intercept is 8 so it passes through (0,8)

to find the x-intercept, set y to equal zero

0=2x+8

-8=2x

x=-4

the x-intercept is -4 so it passes through (-4,0)

the slope is 2 based on the slope-intercept form
