Answer:
<u>Step-by-step explanation:</u>
5x + 2y = 7 ⇒ 2(5x + 2y = 7) ⇒ 10x + 4y = 14
-2x + 6y = 9 ⇒ 5(-2x + 6y = 9) ⇒ -10x + 30y = 45
34y = 59
<u>÷34 </u> <u>÷34 </u>
y = 59/34
Answer:
2nd option
Step-by-step explanation:
tan x = = =
Answer: if this is supposed to be in slope-intercept form
the equation would be: y = -2/5x + 7
Step-by-step explanation:
so the slope is: -2/5 and the point is (10,3) considering that x = 10 and y = 3
so we would plug this information into this equation: y = mx + b (slope-intercept form)
3 = -2/5(10) + b
3 = -4 + b
b = 7
and if we plug this in:
y = -2/5x + 7
