A small plant is 2 1/2 inches tall. How tall will it be in 3 weeks if it grows 34 inch each week? Which method will NOT give the correct number of inches? CLEAR CHECK Multiply 212×3, and then add 34. Multiply 3×34, and then add 212. Add 212+34+34+34. Multiply34×3, and then add 212.

The method that will not give the correct number of inches is:

Multiply 2 1/2×3, and then add 34.

Step-by-step explanation:

A small plant is 2 1/2 inches tall. How tall will it be in 3 weeks if it grows 34 inch each week?

For the first week

2 1/2 inches + 34 inches

For 3 weeks

= 2 1/2 inches + 3(34) inches

= 2 1/2 inches + (34 + 34 + 34)inches

= 2 1/2 inches + 102 inches

= 104 1/2 inches

The height of the small plant after 3 weeks

= 104 1/2 inches

Which method will NOT give the correct number of inches?

The method that will not give the correct number of inches is:

Multiply 2 1/2×3, and then add 34.

b

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

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
