[tex]y = x - 5[/tex]
Substitute y in the x+3y=9
[tex]x + 3(x - 5) = 9 \\ x + 3x - 15 = 9 \\ 4x = 9 + 15 \\ 4x = 24 \\ x = 6[/tex]
Substitute x = 6 in any given equations. I will choose to substitute in y = x-5
[tex]y = x - 5 \\ y = 6 - 5 \\ y = 1[/tex]
The answer is (6,1)
Please help me- thank you

The function LaTeX: c\left(t\right)=1.75+0.85\left(t-1\right)c ( t ) = 1.75 + 0.85 ( t − 1 ) represents the cost to call China as a function of the time, in minutes, t, on the phone. When will the cost first exceed $57?
Given:
The cost to call China as a function of the time, in minutes, t, on the phone is
[tex]c(t)=1.75+0.85(t-1)[/tex]
To find:
The time when the cost first exceed $57.
Solution:
The cost first exceed $57 means cost is greater than $57.
[tex]c(t)>57[/tex]
[tex]1.75+0.85(t-1)>57[/tex]
[tex]0.85(t-1)>57-1.75[/tex]
[tex]0.85(t-1)>55.25[/tex]
Divide both sides by 0.85.
[tex]t-1>\dfrac{55.25}{0.85}[/tex]
[tex]t-1>65[/tex]
[tex]t>65+1[/tex]
[tex]t>66[/tex]
Therefore, after 66 minutes the cost to call china will exceed $57. It means first at t=67 the cost will exceed $57.

find an equation for the perpendicular bisector of the line segment whose endpoints are (-7, 1) and (-1,-3)
Answer:
2y + x = -5Step-by-step explanation:
The standard form of the equation is expressed as y = mx+c
m is the slope
c is the y-intercept
Given the coordinate points (-7, 1) and (-1,-3)
m = y2-y1/x2-x1
m = -3-1/1+7
m = -4/8
m = -1/2
Get the intercept
y = mx+c
1 = -1/2(-7) + c
1 = 7/2 + c
c = 1-7/2
c = -5/2
Get the equation
y = mx+c
y = -1/2 x - 5/2
2y = -x - 5
2y + x = -5
Hence the required equation is 2y + x = -5

A polynomial has been factored, as shown below:
f(x) = (x - 9)(x + 12)(x - 24)
What are the zeros of the polynomial?
1)-9,9, -12, 12, -24, 24
2) -9, 12, -24
3) 9.-12, 24
4) 9, 12, 24
To find the zeros of a polynomial, you make every factored parentheses equal to zero. You basically make the other side equal to zero and solve for x.
So,
[tex]f(x)=(x-9)(x+12)(x-24)\\0=(x-9)(x+12)(x-24)\\x-9=0\\x=9\\x+12=0\\x=-12\\x-24=0\\x=24[/tex]
Your zeros are x = 9, -12, 24
So your answer is 3) 9, -12, 24

Square RSTU is inscribed in circle P. Given the coordinates for the vertices of the square, find the equation of circle P.
R(0, 4), S(6, 2), T(4, -4), and U(-2, -2)
9514 1404 393
Answer:
(x -2)² +y² = 20
Step-by-step explanation:
The center of the circle is the midpoint of either diagonal of the square. The midpoint of RT is ...
(R +T)/2 = ((0, 4) +(4, -4))/2 = (4, 0)/2 = (2, 0)
The square of the radius is the square of the distance between the center any any point on the circle. The distance (squared) from the center to R is ...
d² = (x2 -x1)² +(y2 -y1)²
d² = (0 -2)² +(4 -0)² = 4 +16 = 20
The circle with radius² = r² and center (h, k) has equation ...
(x -h)² +(y -k)² = r²
Our circle has (h, k) = (2, 0) and r² = 20, so the equation is ...
(x -2)² +y² = 20
a reciprocal is a number that
Answer:
The reciprocal of a number is 1 divided by the number. The reciprocal of a number is also called its multiplicative inverse. The reciprocal of a fraction is found by flipping its numerator and denominator.
The reciprocal of a number is this fraction flipped upside down. In other words, the reciprocal has the original fraction's bottom number—or denominator—on top and the top number—or numerator—on the bottom. So the reciprocal of 6 is 1/6 because 6 = 6/1 and 1/6 is the inverse of 6/1. Below, you can see more reciprocals.

If FGH QRS, find the measure of Q
A. 9
B.28
C.11
D.34
Answer:
28°Step-by-step explanation:
Since ΔFHG ≅ QRC, the corresponding angles are congruent:
∠F = ∠Q(2x + 10)° = (3x + 1)°3x - 2x = (10 - 1)°x = 9°Then, the angle Q measures:
∠Q = (3*9 + 1)° = 28°Which of the following shows the length of the third side, in inches, of the triangle below? (1 point)
A right triangle is shown. One side of the triangle is labeled shown as 73 inches. The height of the triangle is labeled as 48 inches.
Question 10 options:
1)
121
2)
Square root of 7633
3)
55
4)
Square root of 25
Answer:
2, sqrt of 7633
Step-by-step explanation:
for now, we'll leave the 3rd side as x
y using the Pythagorean theorem, we can conclude that (1) 48^2+x^2=73^2 or (2) 48^2+73^2=x^2.
1. If we conclude the x isn't the longest, the x would be 3025 which is the sqrt of 55, now is invalid because the 2 smallest sides can't be more than the longest side when they add up 55+48>73 so that is invalid
2. Then, it leaves us with only 1 choice left! concluding that the 3rd side is the longest. Which the answer is sqrt of 7633
