Answer:
3) 5/2
Step-by-step explanation:
5x - 2y = 20
(First, put it in slope intercept form: y = mx + b).
5x - 2y - 5x = 20 - 5x --> Subtracted 5x on both sides of the equation
- 2y = -5x + 20 --> Simplified
-2y/-2 = (-5x + 20)/-2 --> Divided by -2 on both sides
y = 2.5x - 10 --> Simplified
Since formula is, y = mx + b, then:
m (slope): 2.5
b (y-intercept): -10
Therefore, the answer is 3) 5/2
Hope this helped! <3
Let's solve for y.
5x − 2y = 20
Step 1: Add -5x to both sides.
5x−2y+−5x=20+−5x
−2y=−5x+20
Step 2: Divide both sides by -2.
−2y/−2 = −5x + 20/−2
y = 5/2x − 10
Answer:
y = 5/2x − 10
Slope = x, therefore, the slope = 5/2.

1/2=2m then what is m?
Answer:
m = 1/4 or 0.25
Step-by-step explanation:
1/2 = 2m
[Symmetric property of equality]
2m = 1/2
÷2. ÷2
[Division property of equality]
m = 1/2 ÷ 2
m = 1/4
________
1/2 = 2m → 1/2 = 2(1/4) → 1/2 = 2/4 →
1/2 = 2÷2/4÷2 → 1/2 = 1/2

Answer:
B. -7
Step-by-step explanation:
Formula to find slope is (y2-y1) / (x2-x1)
Here we have 4 points to choose from, but we only need 2. I will use the first 2 points.
The y2 is 7, the y1 is 14, the x2 is 3, the x1 is 2.
Substitute these numbers into the formula.
(7-14) / (3-2)

A store sells a package of 25 trading hearts for $5.25 use pencil and paper explain how you can tell that the unit price per card is less than $1 what is the unit price per card.
Answer:
Unitary cost per card= $0.21
Step-by-step explanation:
Giving the following information:
Number of cards per packecge= 25
Total cost per package= $5.25
To calculate the unitary cost of each card, we need to use the following formula:
Unitary cost per card= total cost / number of cards per package
Unitary cost per card= 5.25 / 25
Unitary cost per card= $0.21
Solve for x:
7x = 105
Answer:
X=15
Explanation: You have no like terms to combine and are at the last step of the algebraic equation. So, you would divide 7 on both sides. 7 by 7 cancels it out and 105 divided by 7 equals 15. Hope this helps ^-^.
The solution to the equation 7x = 105 is x = 15.
We have the equation: 7x= 105
To solve for x in the equation 7x = 105, we need to isolate x on one side of the equation.
Divide both sides of the equation by 7:
(7x)/7 = 105/7
Simplifying:
x = 15
Therefore, the solution to the equation 7x = 105 is x = 15.
