Answer:
-3/4
Step-by-step explanation:
To find the slope, plug the coordinates into the slope formula.
y2 - y1 / x2 - x1
4 - (-2) / -7 - 1
6 / - 8
-3/4
Answer:
$1.50 per pound
Step-by-step explanation:
$6 for 4 lb
$6 / 4
since wanting to figure out how much 1 lb cost then divide the total by 4 since $6 is 4 lb
6 / 4 = 1.5
hope this helps
Simplify equation: 14 - 7y + 5 = 1 + 3y + 24
simplify again: 19 - 7y = 25 + 3y
add -25 and 7y to both sides: -6 = 10y
y = -6/10 or -0.6
2. After 30 minutes, richie has delivered 1/3 of the papers, so they have to deliver the remaining 2/3. Since they can deliver them all in 40 minutes, would the answer be 2/3 of 40? I'm not sure about this.
Answer:
x = 40
Step-by-step explanation:
3x + (x+20) = 180
So,
Let's manipulate this into the y=mx + b form.
Add 4x to both sides
-6y = 4x + 24
Divide both sides by -6

Just use the slope to find the points you need.
The y-intercept is
(0,-4).The slope is

. Finding the next point:
(-6,0)You could have also used the <em>slope intercept method.</em>
-4(0) - 6y = 24
-6y = 24
Divide both sides by -6
y = -4
(0,-4)-4x - 6(0) = 24
-4x = 24
Divide both sides by -4
x = -6
(-6,0)
