Answer:
Step-by-step explanation:
Alexis earned to equal Eduardo earned in how many weeks
Alexis earned 115 + 50w = Total w equals weeks
Eduardo earned 130 + 40w = Total w equals weeks
subtract equations -15 + 10w = 0
10w = 15
w = 1.5 weeks they both will have $190
Y = 9x - 5...the slope here is 9...a parallel line will have the same slope.
y = mx + b
slope(m) = 9
(5,-4)...x = 5 and y = -4
now we sub and solve for b, the y int
-4 = 9(5) + b
-4 = 45 + b
-4 - 45 = b
-49 = b
so ur parallel line is : y = 9x - 49
y = 9x - 5...slope is 9. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -1/9.
y = mx + b
slope(m) = -1/9
(5,-4)...x = 5 and y = -4
now we sub and solve for b, the y int
-4 = -1/9(5) + b
-4 = -5/9 + b
-4 + 5/9 = b
-36/9 + 5/9 = b
- 31/9 = b
so ur perpendicular line is : y = -1/9x - 31/9
Answer:
54×8=432 1452-150=1302×.25=325.50+432.00=757.50
Step-by-step explanation:
<span>(f+g)(x) = 2x+21 +x-24
= 3x -3
now put x=3 in order to find (f+g)(3)
(f+g)(3) = 3(3) -3
= 9-3
= 6, i hope this helps </span>
Answer:
188 sq m
Step-by-step explanation:
for the top square its just 6 x 6 which is 36
then for the bottom you add 6 + 13 for the width (which is 19) and we've already been given 8 for the height so then you multiply 19 x 8 and get 152
you then add 152 and 36 to get 188 (and the unit is sq m or m^2)
