Of the students in Jill's grade, 41 students have a pet and the other 7 students do not. What is the ratio of the number of students who do not have a pet to the total number of students?

The answer is 7 : 48.

Step-by-step explanation:

First, you can to calculate how many students are there in Jill's grade by adding the number of students who have pet with the students without pets :

total = 41 + 7 = 48

Next, you have to find the ratio of students without pets to total students :

7 : 48

Total student = Student who have pet + Student who don't have pet

Total Student = 41 + 7

Total Student = 48

Ratio

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

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
