Answers

1/2 is the slope. pick 2 points and go up and then over.

Answer:

Slope: [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Slope is : [tex]\frac{rise}{run}[/tex]

If we start at the plotted point (0,0), to travel to the plotted point (2,1) following rise over run pattern you would go up 1 unit for it to correspond the set point and 2 units to the right to reach the exact point.

Answer:

C: y= 1/50x + 4

Step-by-step explanation:

Since margo drove 200 miles to her aunts house and was left with 8 gallons of gas in the tank of her car when she arrived, we just plug the variables we know in the equation to get the answer. she drove 200 miles, so x=200. 1/50x is 1/50 times 200 aka 4. So now we just add the 4 at the end of the equation and 4 + 4 is 8. This is true, we know she had 8 gallons of gas left when she arrived and she drove 200 miles. So C is the correct answer.

C: 1/50x + 4
Therefore the answer should be C...HOPE I COULD HELP GOOD LUCK:))

P.S - The exact question is -
Given - Mr. Sanders wants to display his American flag in a triangular case as shown below.
To find - What is the area of the triangular case ?
Proof -
Given that,
Base of triangle = 14 2/5 in
Height of triangle = 8.5 in
We know that,
Area of triangle =1/2 *base *height =1/2 *8.5 *14 2/5
=1/2 * 8.5 * 14.4
=1/2 * 122.4
=61.2

we get
The area of the triangular case = 61.2 square inches
