Will mark as brainliest and rated excellent if answer is right. The ratio of boys to girls in a group is 7:2. If there are 70 more boys than girls, work out how many people there are in total.

Step-by-step explanation:

Boys: girls = 7:2

No. of boys = 7x

No. of girls = 2x

7x - 2x = 70

5x = 70

x = 70/5

x = 14

No. of boys = 7x = 7*14 = 98

No. of girls = 2x = 2*14 = 28

Total = 98 + 28 = 126

step-by-step explanation: easy

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
