Can someone help me 1 or 4

sleet_krkn [62]

Answer:

No. 1: y = 90 (vertically opposite angles)

Also, x = 9. To find x, we'll have:

$3x + 7 + 56 + 90 = 180 \\ (sum \: of \: angles \: on \: a \: straight \: line) \\ 3x + 153 = 180 \\ 3x = 180 - 153 \\ 3x = 27 \\ \frac{3x}{3} = \frac{27}{3} \\ x = 9.$

No. 4: y = 62 (vertically opposite angles)

Also, x = 12. To find x, we have:

$5x = 60 \\ \frac{5x}{5} = \frac{60}{5} \\ x = 12.$

Find the missing value so that the two points have a slope of 2/7. (-1,-1) and (x,1)

Radda [10]

Answer:

x = 6

Step-by-step explanation:

Slope = (y(2) - y(1))/(x(2) - x(1))

(-1 - 1) / (-1 - x)

If the slope is 2/7, it would be (-2/-1-x, where x would have to be 6)

(-2)/(-7) = 2/7, so x = 6

Check:

(-1 - 1) / (-1 - 6)

(-2)/(-7)

2/7 (Correct :))

Hope it helps :D
