The equations of both plants are given where x represents the time in weeks and y represents the heights of the plants in inches. Plant A: y = 1.8x + 3.1 Plant B: y = 2.3x + 1.9 Approximately how many weeks will it take for both plants to reach the same height? Round your answer to the nearest tenth. 1.9 weeks 2.4 weeks 3.1 weeks 7.4 weeks

Step-by-step explanation:

x represents the time in weeks

y represents the heights of the plants in inches.

Plant A: y = 1.8x + 3.1

Plant B: y = 2.3x + 1.9

We would equate both plants together

Plant A = Plant B

Plant A: y = 1.8x + 3.1

Plant B: y = 2.3x + 1.9

Hence:

1.8x + 3.1 = 2.3x + 1.9

Collect like terms

3.1 - 1.9 = 2.3x - 1.8x

1.2 = 0.5x

x = 1.2/0.5

x = 2.4 weeks

Hence, it would take 2.4 weeks for Plant A and Plant B to reach the same height

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
