Consider the line y=9x-8

Mathematics

1 answer:

Answer:

y=9x+75

Step-by-step explanation:

since we know that the slope must be the same for two lines to be proportional, we are gonna start there.

so our equation is: y= 9x + b

we need to find b to complete our equation, so substitute in the points we were given.

3 = 9(-8) + b

so now,

3 = -72 + b

now we have to isolate b to find out what it is,

3 = -72 + b

+72 +72

so now: 75= b

Put that back into the starting equation: y = 9x + 75

Brandon made $38.00 in 3 hours. How much would he make in 10 hours

Bad White [126]

Answer:

He would make $126.70 in 10 hours.

Step-by-step explanation:

First, you have to find the unit rate, in other words, how much money he earns in one hour. To do that, you have to divide.

38.00÷3= 12.666667

Once you know how much money Brandon earns in one hour($12.67), you multiply that number by 10.

12.67×10= 126.70

In conclusion, the answer to this solution($126.70) is how much money he earns in 10 hours.

Part B: In complete sentences, explain how a circle can be used to find the circumcenter of the triangle graphed below.

Karo-lina-s [1.5K]

Answer:

Step-by-step explanation:

Part B:

The center of the circumscribed circle around a triangle is equidistant from vertices of that triangle. To find the circumcenter need to draw at least two perpendicular bisectors to the sides of the given triangle. Point of intersect of them is center of the circumscribed circle.

Part C:

Coordinates of the midpoint of line BC ( y = - 1 ) are

( $\frac{-6+2}{2}$ , $\frac{-1-1}{2}$ ) = ( - 2 , - 1 ) and the equation of the line ⊥ to BC is x = - 2

Because BC is ║ to x-axis and m∠A is 90° , the center of the circle is midpoint of BC and r = $\frac{BC}{2}$ = 4

Three-eighths of the sum of sixteen times a number and twenty-four. How do you set this up?

patriot [66]

If you break it up:

Three-eighths = 3/8

Sixteen times a number, we'll call the unknown number X, so 16X.

Twenty Four = 24

The sum of 16X and 24 = 16X + 24

We want 3/8 of that sum so we put the sum in parenthesis and we get:

Y = 3/8(16X + 24) where Y is the answer youd get if you knew what X was.
