Step-by-step explanation:

Because Jen has fewer marbles than Jay so we take the number of Jay's marbles and minus with the number of marbles tan Jay has more than Jen so that we have the number of Jen's and we add it with Jay's number of marbles to have the number of marbles they have

In slope-intercept form, write the equation of the line that passes through points (-7, 8) and (2, -2).
Ymorist [56]

Answer:

y = -1x + 0.5

Step-by-step explanation:

First, I plotted the points (-7, 8) and (2, -2). Then, I drew a line connecting the two points. At the point (-7, 8), I went down 2 squares and to the right 2. This would give me a slope of -1. Since the line touches the y-axis at 0.5, this is the y-intercept.

I am not sure about the y-intercept of this equation. If I got this wrong, I am sorry and please let me know. Thank you!

2. Solve each given equation and show your work. Tell whether each equation has one solution, an infinite number of solutions, o
Brut [27]

Hello!

To solve algebraic equations, we need to use SADMEP. SADMEP is an acronym used only solve for x in algebraic equations. SADMEP is expanded to be: subtraction, addition, division, multiplication, exponents, and parentheses.

(a) 4 + 2(-1) = 10 + 2 (multiply)

4 + -2 = 10 + 2 (add)

2 = 12

This equation has no solutions because <u>2 is never equal to 12</u>.

(b) 30 = 10 - (6 + 10) (simplify the parentheses)

30 = 10 + -1(16) (multiply)

30 = 10 - 16 (simplify)

30 = -6

This equation has no solutions because<u> 30 and -6 is never equal to each other</u>.

(c) 8x = 4x + 4x + 10(x - x)

8x = 4x + 4x + 10(x - x) (simplify [add and subtract])

8x = 8x + 10(0) (multiply)

8x = 8x  

This equation has an infinite number of solutions because if you <u>substitute any value into the original equation</u>, <u>both sides of the equation</u> will be <u>always equal</u>.
