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
Answer:
2x + 5y = 4.70
Step-by-step explanation:
Rider ordered 2 hot dogs and 5 hush puppies. His total was $4.70. Write an equation in standard form for this relation, using
From the above question, note that
x = cost of a hot dog
y = cost of a hush puppy.
Our Standard Equation is given as
2 × x + 5 × y= $4.70
2x + 5y = 4.70
Answer:
10 windows
Step-by-step explanation:
2.5x2.5=6.25 then you would do 64 divided 6.25 to get 10.24 which would give you 10 whole windows.
Answer:
X=-3/2
Step-by-step explanation:
-2(x+2)=-1
Distribute
-2*x and -2*2
-2x-4=-1
Solve for x
-2x-4=-1
+4 +4
-2x=3
/-2 /-2
x=-3/2
