Which value of x is a solution to this equation and graph shown?

5 points

A. x= 12

B. x=6

C. x= -1.8

D. x= -28

b. x=6

Step-by-step explanation:

to know which value of x is a solution

it is in the graph where the graph intersects the x line

there are 2 possibilites because the graph intersects the x line twice because it is a quadratic equation

on the graph where the two dots are, those are the two answers, about 1 and also 6

6 is one of your answers so it is the answer to your question

it can't be 12 because the dot is before 10

it can't be -1.8 or -28 because those are both negative numbers which the graph doesn't go through the -x part of the graph at all

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
