Answer:

$\displaystyle b = - 14$

$\displaystyle c = - 54$

Step-by-step explanation:

to figure out b we can consider the following formula:

$\displaystyle \frac{ - b}{2a} = h$

the form of vertex coordinate given by

$\displaystyle (h,k)$

so according to the question

$\displaystyle (h,k) = ( - 7, - 5)$

by order pair we obtain:

$\displaystyle h = - 7, k = - 5$

now substitute the value of h and a to the formula:

$\displaystyle \frac{ - b}{2(- 1)} = - 7$

simplify multiplication:

$\displaystyle \frac{ - b}{ - 2} = - 7$

cross multiplication:

$\displaystyle - b = 14$

divide both sides by -1:

$\displaystyle b = - 14$

now we need to figure out C to do so substitute -7 for x and -5 for y which yields:

$\displaystyle - {7}^{2} - 14( - 7) + c = - 5$

simplify square:

$\displaystyle -49 - 14( - 7) + c = - 5$

simplify multiplication:

$\displaystyle -49 + 98+ c = - 5$

simplify addition:

$\displaystyle 49+ c = - 5$

cancel 49 from both sides:

$\displaystyle c = - 54$

hence,

b=-14
C=-54

The diameter of a merry-go-round is 63 feet. Each person gets to make 23 rounds per ride. How far does each person ride?

xenn [34]

Calculate the circumference of the circle, and multiply it by 23.

C = pi * d

C = 3.14 * 63 ft =197.82 ft

23 * C = 23 * 197.82 ft = 4549.86 ft

Which ordered pair makes both inequalities true?

kvasek [131]

Answer:

(3, 0)

Step-by-step explanation:

Given the inequality y > -2x + 3 and y ≤ x - 2

The graph of the inequalities are plotted using the geogebra graphing online calculator.

The portion of the graph that is shaded with dark blue, represents the portion that supports the equation.

All the ordered pair points given in the question are also labelled in the graph.

From the graph we can see that only point (3, 0) falls in the area that supports the equation. Hence (3, 0) makes both inequalities true.
