Answer:
Step-by-step explanation:
center (-1, -2) , trough point ( 6, 4)
equation of the circle
r² = (x-h)²+(y-k)², where (h, k) are the coordinate of a circle so h=-1, k=-2
r² =(x+1)²+(y+2)², but (x, y ) are coordinates for any point on the circle so x=6 and y= 4
r² =(6+1)²+(4+2)²
r²= 7² +6²
r²= 85
so the equation is
(x+1)²+(y+2)²= 85
to find the points on the circle substitute in the equation x and y
(-10+1)²+(0+2)²= 85 ; 85=85 true
so the pint on the circle is (-10, 0)

17 + 4x = 94. Solve for x.
Answers
______________________________
1.) Subtract 17 from both sides:[tex]17-17=[/tex] Cancels Out[tex]94-17=77[/tex]
- We do this to get 1 number left over at the end sum of the equation. To do this you do the opposite of what you see. In this case we have a positive 17, so you subtract 17 on each side.
2.) Divide both sides by 4:[tex]4x[/tex] ÷ [tex]4=x[/tex][tex]77[/tex] ÷ [tex]4=19.25[/tex]
- We do this to get x alone. To do this you do the opposite of what you see. In this case we have [tex]4(x)[/tex] being multiplied, so you divide by 4 on each side.
So your answer is [tex]\bold{19.25}[/tex].

Answer:
x= 77/4
Step-by-step explanation:
(You will first have to rearrange terms)
17+4x-94
4x+17=94
(Now you will have to subtract 17 from both sides of the equation.)
4x+17=49
4x+17-17=94-17
(You will have to simplify now)
4x=77
(You will have to divide from both sides of the equation by the same term.)
4x=77
4x=77
--- --- (Divide by 4.)
4 4
(you will now simplify)
x=77/4
and that's how you get your answer.

Step-by-step explanation:
In a right triangle where the angles are 45, 45 and 90, the hypotenuse is equal to [tex]\sqrt{2}[/tex] multiplied by the length of the legs. Knowing this, we can set up the following equation:
[tex]9=x\sqrt{2}[/tex]
Multiply both sides by [tex]\sqrt{2}[/tex]
[tex]9\sqrt{2} =x\sqrt{2}*\sqrt{2}\\9\sqrt{2} =2x[/tex]
Divide both sides by 2
[tex]\frac{9\sqrt{2}}{2}=\frac{2x}{2}\\\frac{9\sqrt{2}}{2}=x[/tex]
[tex]x=6.36[/tex] (this answer is approximate)
Therefore, x is equal to 6.36.

Reggie is deciding when to go bowling with his friends. Friday night is glow-bowling night,
with 5 glow-bowling games for $22.50. But the early-bird special on Saturday morning offers
8 games for $30. How much more does glow-bowling cost per game?
Answers
Answer:
glow bowling costs $0.75 more per game
Step-by-step explanation:
1. divide $22.50 by 5 games to find the price per game for glow-bowling, which comes out to $4.50
2. divide $30.00 by 8 games to find the price per game for the early-bird special, which comes out to $3.75
3. subtract $3.75 (early-bird bowling) from $4.50 (glow-bowling) and it = $0.75
4.50-3.75=0.75

What is the sign of f on the interval?
Answers
The function f(x) will be sometimes positive and sometimes negative on the interval
Option (3) is correct.
What is a function?An arrangement known as a function connects inputs to essentially one output.
In other words, a function is a relationship between variables, and the nature of that relationship—for example, y = sinx and y = x +6—defines the function.
Given function:
f(x) = (x - 5) (2x - 7) (7x - 3)
The term (x - 5) will be negative if x < 5.
The term (2x - 7) will be negative if x<3.5
So, If x = 4, (x - 5) will be negative but (2x - 7) will be positive, resulting in a negative overall value.
Therefore, if x = 3, then (x - 5) will be negative, as well as (2x - 7), making the whole value negative.
Hence, the function f is sometimes positive and sometimes negative on the interval.
