Answer:
-8.8
Step-by-step explanation:
combine terms on right side of equal sign(50)
know your equation is -5v+6=50
subtract 6 from both sides so you know have -5v=44
then divide both sides by negative five so know you have v=-8.8
(plug in -8.8 to check)
Answer:
Which plant was taller when Nara got the plants? C. They were equally tall
Which plant grew faster? B. The second plant
Step-by-step explanation:
Slope of the first plant :
m = (y2 - y1)/(x2- x1)
m = (36 - 34)/(15 - 10) = 0.4
y-intercept of the first plant :
y = m*x + b
b = y1 - m*x1
b = 34 - 0.4*10 = 30
From the picture we can see that the y-intercept of the second plant is 30 cm
Y-intercept represents plant heights when Nara got the plants; then they were equally tall
From the picture we can see that second plant grew 2 cm in 2 days; then its slope is 2/2 = 1
Slope measures how fast each plant grew; then the second plant grew faster
20 and 10, 20 is 2 times 10 and if you add them together its 30
