Jessica is saving for college. She makes a $75 deposit each week into her savings account. She also decided to use some of the m

oney from the savings account to buy a new music player for $225. The inequality 75x−225≥975 can be used to find x, the number of weeks it will take Jessica to have at least $975 in the account for college. Which graph shows the solution of this inequality?

75x-225> or equal to 975
Add 225 from both sides
75x = 1200
X = 16

So x > or equal 16

Write an equation in slope-intercept form for each line.<br> (4,-1) and (-2,-1)
professor190 [17]

With each line, a slope-intercept relationship (4,-1) and (-2,-1).

Y = 0 ,X = 5.

<h3>What is slope-intercept form?</h3>

The slope-intercept form is just a means of stating a line's equation so that both the slope (steepness) as well as y-intercept (where another line crosses this same vertical y-axis) are obvious. This expression is frequently referred to as y = mx + b.

<h3>According to the given information:</h3>

To begin, are using the slope formula to figure out the average slope between two points here.

Let:

x1 = 4

y1 = -1

x2 = -2

y2 = -1

m = (y2-y1)/(x2-x1)

= (-1 - (-1))/ (4-(-1))

= 0/5

= 0

So the slope is 0.

We must now calculate the y-intercept. This will be accomplished by converting a single of the points and also the slope together into a point-slope linear equation. y2-y1 = m(x2-x1).

Let’s plug in the point (5,0).

So we get y-(-0) = (0/5)(x-(-5)) ⇒  y+0

= (0/5)x +  0 ⇒  y

So,

Y = 0

X = 5

with each line, a slope-intercept relationship (4,-1) and (-2,-1).

Y = 0 ,X = 5

I have no idea how to solve this
Pavlova-9 [17]
  • <em>Answer:</em>

<em>x = 25</em>

  • <em>Step-by-step explanation:</em>

<em>Hi there ! </em>

  • <em><u> the opposite angles are equal</u></em>

<em><u>4x - 25 = 25 + 2x</u></em>

<em><u>4x - 2x = 25 + 25</u></em>

<em><u>2x = 50</u></em>

<em><u>x  = 50 : 2</u></em>

<em><u>x = 25</u></em>

<em><u>Good luck ! </u></em>
