Answer:
C(5, -3)
Step-by-step explanation:
Given the equation of circle;
x² + y² - 10x + 6y - 2 = 0
The general equation for a circle is given by the formula;
x² + y² + 2gx + 2fy + c = 0
Where the center is C(-g, -f)
To find the center, we would compare the two equations;
For the value of g.
2gx = -10x
2g = -10
g = -10/2
g = -5
To find the value of f.
2fy = 6y
2f = 6
f = 6/2
f = 3
Therefore, the center C(-g, -f) = (-(-5), -(3))
C(-g, -f) = C(5, -3).
Alang went to the store to buy some walnuts. The price per pound of the walnuts is $7 per pound and he has a coupon for $2.50 off the final amount. With the coupon, how much would Alang have to pay to buy 2 pounds of walnuts? Also, write an expression for the cost to buy pp pounds of walnuts, assuming at least one pound is purchased.
Answer:
$11.50 is the cost for 2 pounds of walnuts
Expression: 7p - 2.50
Step-by-step explanation:
First, create an expression to represent the cost:
7p will represent the cost, since the walnuts are $7 per pound, and 2.50 needs to be subtracted from this because of the coupon for $2.50 off
So, the expression is 7p - 2.50
Use this expression to find the price for 2 pounds of walnuts:
7p - 2.50
7(2) - 2.50
14 - 2.50
= 11.50
So, the cost with the coupon will be $11.50

Step-by-step explanation:
Idendify the slope and y-intercept from the equation below.
(Hint: rewrite the equation in slope-intercept form first.)
10x - y = 5
m =
y =
Answer:
m=10 y=5 / (0, 5)
Step-by-step explanation:
Slope-int form: y=mx+b
So;
10x-y=5
+10x +10x
y = 10 x + 5
Caitlin recently rode her bicycle to visit her friend who lives 9 miles away. On her way
there, her average speed was 8 miles per hour faster than on her way home. If Caitlin
spent a total of 3 hours bicycling, find the two rates.
15 points help me please. show steps!!
Answer:
12 mph & 4 mph
Step-by-step explanation:
Let s and s - 8 be the speed of Caitlin going on her friend and her speed on her way home respectively.
Distance = Speed × Time
Distance/Speed = Time
9/s + 9/(s - 8) = 3
9(s - 8) + 9s = 3s(s - 8)
9s - 72 + 9s = 3s² - 24s
3s² - 42s + 72 = 0
s² - 14s + 24 = 0
(s - 2)(s - 12) = 0
s - 2 = 0
s = 2
s - 12 = 0
s = 12
If s = 2, then s - 8 = - 6 < 0. We want s and s - 8 to be positive so s = 12 mph. It follows that her speed on her way home is 4 mph.

A grill at a barbecue restaurant will be used to cook sausage links that are 2 lb each and briskets that are 6 lb each. No more than 120 lb of sausage links and briskets will be cooked on the grill.
Which inequality represents all possible combinations of x, the number of sausage links that will be cooked on the grill, and y, the number of briskets that will also be cooked?
Answer:
2x + 6y ≤ 120
Step-by-step explanation:
From the above question, we are told that: No more than 120 lb of sausage links and briskets will be cooked on the grill.
Let
x = Number of sausage links
y = Number of Briskets
The word NO MORE THAN means less than or equal to 120 lb and this word is represented by the inequality sign:
≤
Sausage links = 2 lb each
Briskets = 6 lb each
The inequality =
2lb × x + 6lb × y ≤ 120lb
2x + 6y ≤ 120
Therefore, the inequality represents all possible combinations of x, the number of sausage links that will be cooked on the grill, and y, the number of briskets that will also be cooked is given as:
2x + 6y ≤ 120
