Answer:
B = 49/5 - 7a/5
A = = -5b/7 + 7
Step-by-step explanation:
Given that,
7a+ 5b= 49
Solution:
<em>Solving for a:</em>
Add -5b to both sides:
Divide both sides by 7:
Hence,a = -5b/7 + 7.
<em>Solving for b:</em>
Add -7a to both sides:
Divide both sides by 5:
Hence,b = 49/5 - 7a/5.
Answer:
Your answer would be A
Step-by-step explanation:
Solve the first equation by moving 2x to the right side and changing the sign:
2x + y = –4
y = –2x — 4
Solve the second equation by dividing both sides by –3
–3y = 2x + 12
y = 2x/–3 + 12/–3
y = –(2x/3) — 4
Now that both are written in slope-intercept form, start graphing. Your variable is the slope. The constant is the y-intercept. The y-intercept is always graphed first. In the first equation, your slope is –2 and your y-intercept is –4. The point of your y-intercept is (0, –4). To graph the slope, you use rise/run. For the slope of –2, you go down 2 and move over one to the right.
For the second equation, the slope is negative two-thirds and the y-intercept is –4. Graph the y-intercept first. The point of the y-intercept is on (0, –4). For the slope, go down 2 and move 3 to the right. Now find the intersection and matching graph to fins your answer.
