Giving brainliest! (30 points)
a car manufacturer is reducing the number of incidents with the transmission by issuing a voluntary recall. during week 3 of the recall, the manufacturer fixed 391 cars. in week 13, the manufacturer fixed 361 cars. assume that the reduction in the number of cars each week is linear. write an equation in function form to show the number of cars seen each week by the mechanic.
f(x) = 3x + 400
f(x) = 3x + 391
f(x) = −3x + 391
f(x) = −3x + 400

Option d is the right answer

Step-by-step explanation:

Given that a car manufacturer is reducing the number of incidents with the transmission by issuing a voluntary recall.

Let x represent the number of weeks and y no of cars fixed

Then given that the relationship is linear.

Hence we have two points lying on the line as two numbers in given information

Using two point formula we get equation of line as

Option d is right.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
