Answer:
Step-by-step explanation:
Given:
The two points on the line are and .
The slope of the line joining two points and is given as:
Here,
∴
Equation of line with a point and slope is given as:
Plug in -2 for , 3 for and -7 for . This gives,
Therefore, the equation of the line in vertex form is .
The answer is C
Because radical 38 would equal approximately 6.1644, which is what the line shows.
Make the length x+4 and the width x and then make a formula x(x+4)=21
then u ll get x^2+4x-21=0 and then solve for x ..... the width is 3
i really don't understand what you are trying to say but if it was a math problem it would be -1.
Answer:
C. Julie drive 15.5 miles from her home to the grocery store. Julie drives the same path going back home. What is x, the total amount of miles traveled to the grocery store and back home?
Step-by-step explanation:
The situation in the 3rd option represents the equation, 15.5 = x/2.
Distance driven by Julie to the grocery store = 15.5 miles
Distance driven by Julie back home following the same path = 15.5 miles
Total amount of miles travelled to and fro the store, x, = 2*15.5
This means, the mile's covered going to the store or coming back home can be expressed as ½ the total amount of miles, x, covered. Which is: 15.5 = ½x
Therefore, the third option represents the equation, 15.5 = x/2.
