Answer:
3/4
Step-by-step explanation:
The given equation is in the form of y=mx+b
This is where m is the slope, and b is the y intercept.
This said, the slope of the equation is 3/4.
I will attach an image of the graph. I put the equation in a graphing calculator.
If you need to graph by hand, first plot the y intercept, (0,2) and then use the slope to find more points. Then, connenct the points with a ruler.
The image you attached is not the graph of y=3/4x+2, it is the graph of y=5.
It's slope is equal to 0.
<h3>For 10 pounds, both companies cost the same</h3>
<em><u>Solution:</u></em>
Let "x" be the pounds
<em><u>Company A charges $2.50 per pound plus a $20 service charge</u></em>
Cost : 2.50x + 20 ------ eqn 1
<em><u>Company B charges $4.50 per pound without any service charge</u></em>
Cost : 4.50x ------- eqn 2
<em><u>At what weight does it cost the same for both companies?</u></em>
For both companies to cost the same, eqn 1 must be equal to eqn 2
2.50x + 20 = 4.50x
4.50x - 2.50x = 20
2x = 20
Divide both sides by 2
x = 10
Thus for 10 pounds, both companies cost the same
Answer:
1) m ∠B = 132°
2) m ∠B = 113°
Step-by-step explanation:
1. In triangle ABC, m ∠A=36, and m ∠C=12. Calculate m ∠B.
We are given measure of 2 angles and we need to find the third angle.
We know that, sum of angles of triangle = 180°
We can write as:
∠A + ∠B + ∠C = 180°
Now put m ∠A=36 and m ∠C=12, to find m ∠B
So, we get m ∠B = 132°
2. In triangle ABC, m ∠A=40, and m ∠C=27. Calculate m ∠B.
We are given measure of 2 angles and we need to find the third angle.
We know that, sum of angles of triangle = 180°
We can write as:
∠A + ∠B + ∠C = 180°
Now put m ∠A=40 and m ∠C=27, to find m ∠B
So, we get m ∠B = 113°
You divide the miles by the hours
Answer:
x = -2.5 or x = 8
Step-by-step explanation:
(x-8)(2x+5)=0
Set each part = 0 and solve for x
x - 8 =0; x = 8
2x + 5 = 0; x = -5/2 = -2.5
Answer
x = -2.5 or x = 8
