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.

Jana earns $25 per week for mowing the lawn and deposits the money into her savings account. The amount of money in Jana’s accou
photoshop1234 [79]

Slope-intercept form: y = mx + b  [m is the slope, b is the y-intercept or the y value when x = 0  --->  (0, y)  or the point where the line crosses through the y-axis]

y = 25x + 125

"y" would represent the total amount of $ she has saved.

The y-intercept would be 125 or (0, 125), this means that she already/initially had $125 in her savings account, before she started depositing $25 per week
