Answer:
2x + y = - 5
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 2 and (a, b) = (- 1, - 3 ) , thus
y - (- 3) = - 2(x - (- 1)), that is
y + 3 = - 2(x + 1) ← distribute
y + 3 = - 2x - 2 ( add 2x to both sides )
2x + y + 3 = - 2 ( subtract 3 from both sides )
2x + y = - 5
1 = 1.5x -1
+1 +1
2 = 1.5x
/1.5 /1.5
4/3 = x
y = 1.5 ( 4/3 ) -1
y = 1
solution:
x = 4/3
y = 1
M=2j
m+j=480
Substitute 2j for m;
2j+j=480
3j=480
j=160
Jen earns $160 per week.
m=2j
m=2(160)
m=320
Mari earns $320 per week.
Answer:
4 x 9 = 36
14 x 5 = 70
70 + 36 = 106 sq cm
(Not really sure if this is correct but hope it helps).
