3. y-intercept is when x=0, so 2. Slope is change in y divided by change in x, so 4/3, which rounds to 1.3.

4. the equation: y=mx+d, so substitute m for the slope and d as the y-intercept, so you get y=1.3x+2

5. When you look at the graph, when x=7, then y=80. So the student may get an 80.

Can anyone please help me with this???

ira [324]

Answer:

x=8a

Step-by-step explanation:

(3/a) x - 4 = 20

add 4 to both sides

(3/a) x = 24

Divide by 3/a

x = 24 / (3/a)

Use KCF (keep change flip)

x = (24/1) x (a/3)

x = 24a / 3

simplify

x = 8a

A botanist was measuring how tall her plant grew. After two weeks it had grown 12.93 inches.The second week alone it had grown 3

Korolek [52]

Answer:

9.5 inches

Step-by-step explanation:

The relationship is presumed to be ...

(first week's growth) + (second week's growth) = (growth in two weeks)

(first week's growth) + 3.43 inches = 12.93 inches . . . . . fill in the numbers

Subtract 3.43 from both sides of the equation:

first week's growth = 12.93 inches - 3.43 inches

first week's growth = 9.50 inches

The plant grew 9.50 inches in the first week.
