Brooke found the equation of the line passing through the points (-7, 25) and (-4, 13) in slope-intercept form as follows. ○ She found the incorrect slope in step 1.

○She mixed up the x- and y-cordinates when she plugged in the point in step 2.

○ She found the incorrect y-intercept in step 2.

○She mixed up the slope and y-intercept when she wrote the equation in step 3.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.

discriminant = b^2 - 4ac, is for a quadratic equation ax^2 + bx + c = 0 with a not equal to 0.
