The answer to your question is 36
-18 + x(-6)
Substitute x with -9
-18 + (-9) (-6)
Then you get 36
Hey there!
-18 + x(-6)
= -18 + (-9)(-6)
= -18 - 9(-6)
= -18 - (-54)
= -18 + 54
= 36
Therefore, your answer is: 36

(7, -1) 2. What is the slope of a line that is perpendicular to the line joining point A (9, 9)? and point B
Answers
Answer:
-1/5Step-by-step explanation:
Given the point A (9, 9) and B(7, -1)
The slope of the line AB is expressed as:
slope = Δy/Δx
slope = y2-y1/x2-x1
slope = -1-9/7-9
slope = -10/-2
slope = 5
For two lines to be perpendicular, the product of their slope must be -1
mM = -1
M is the slope of the line perpendicular to AB
Substitute m = 5 into the equation
5M = -1
M = -1/5
Hence the slope of a line that is perpendicular to the line joining point A and B is -1/5

Answer:
∠ CDE = 134°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 6 , then
sum = 180° × 4 = 720°
let ∠ BCD = x then ∠ CDE = 2x
sum the angles and equate to 720
121 + 144 + 129 + 125 + x + 2x = 720 , that is
519 + 3x = 720 ( subtract 519 from both sides )
3x = 201 ( divide both sides by 3 )
x = 67
Then
∠ CDE = 2x = 2 × 67 = 134°

B.(1, 4)
C.(-1, 5)
D.(1, -1)
Answers
Answer:
Option C
Step-by-step explanation:
Given the following question:
[tex]2x+4y=18[/tex]
[tex]-3x+2=y[/tex]
To find the answer we need to find the values of each of the variables by solving one equation at a time, and then substitute those answers into each equation in till we have our answers.
[tex]2x+4y=18[/tex]
[tex]-3x+2=y[/tex]
[tex]y-y=0[/tex]
[tex]-3x+2+ -y=0[/tex]
[tex]2-2=0[/tex]
[tex]-3x+-y=0+-2[/tex]
[tex]-3x+3x=0[/tex]
[tex]-y=3x-2[/tex]
[tex]-y\div-1=y[/tex]
[tex]3x+2\div-1=-3x+2[/tex]
[tex]y=-3x+2[/tex]
Substitute y for -3x + 2:
[tex]2x+4y=18[/tex]
[tex]y=-3x+2[/tex]
[tex]2x+4(-3x+2)=18[/tex]
[tex]2x+4(-3x+2)=18=-10x+8=18[/tex]
[tex]-10x+8=18[/tex]
[tex]8-8=0[/tex]
[tex]18-8=10[/tex]
[tex]-10x=10[/tex]
[tex]-10x\div10=x[/tex]
[tex]10\div-10=-1[/tex]
[tex]x=-1[/tex]
Substitute x for -1:
[tex]y=-3x+2[/tex]
[tex]x=-1[/tex]
[tex]y=-3(-1)+2[/tex]
[tex]-3\times-1=3[/tex]
[tex]y=3+2[/tex]
[tex]3+2=5[/tex]
[tex]y=5[/tex]
[tex]x=-1[/tex]
[tex]y=5[/tex]
Your answer is "(-1, 5)" or option C.

Sara was thinking of a number. Sara doubles it, then adds 7 to get an answer of 92.9. What
was the original number?
Answers
Answer:
42.95
Step-by-step explanation:
We just reverse the steps. So we take 92.9 and subtract by 7 to get 85.9. Then we divide that number by 2. So we get 42.95. To check our work, we can use this number and follow the steps Sara did. So 42.95*2=85.9+7=92.9
The original number that Sara was thinking of is 42.95.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
Let's represent the original number "x".
According to the question, we know that:
x × 2 + 7 = 92.9
To determine the original number, we'll want to undo the operations that were done to it.
First, we'll subtract 7 from both sides to undo the addition:
x × 2 = 92.9 - 7
x × 2 = 85.9
Then, we'll divide both sides by 2 to undo the doubling:
x = 85.9 / 2
x = 42.95
Therefore, the original number that she was thinking of is 42.95.

The equation of a circle in general form is x2+y2+20x+12y+15=0 .
What is the equation of the circle in standard form?
(x+10)2+(y+6)2=121
(x+10)2+(y+6)2=225
(x+20)2+(y+12)2=121
(x+20)2+(y+12)2=225
Answers
Answer:
[tex](x+10)^2+(y+6)^2=121[/tex]
Step-by-step explanation:
The standard form of a circle's equation is
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Where (h,k) is the center and r is the radius of the circle.
The equation is given in general form, we need to convert it to the standard form. This can be done by completing squares.
The equation is:
[tex]x^2+y^2+20x+12y+15=0[/tex]
Rearrange x's and y's separate:
[tex]x^2+20x+y^2+12y=-15[/tex]
We have also subtracted 15. Now to complete squares, recall the formula:
[tex](a+b)^2=a^2+2ab+b^2[/tex]
The first two terms are equivalent to the first two terms of the above formula. It's clear that the second term is 2ab=20x. Solving for b:
b=10. Thus, to complete the square, we add 100 to the equation.
The third and fourth terms can also be used to complete the squares for y, knowing that 2ab=12y. In this case:
b=6. To complete this square, we add 36. The equation is now:
[tex](x^2+20x+100)+(y^2+12y+36)=-15+100+36=121[/tex]
Operating and simplifying, knowing that 121=11^2:
[tex]\boxed{\mathbf{(x+10)^2+(y+6)^2=121}}[/tex]

In 1992 the average family income was about 42000, and in 2002 it was about 56256. Let x = 0 represent 1992, x = 1 represent 1993, and so on. Find values for a and b (rounded to one decimal place if necessary) so that f ( x ) = a x + b models the data a = b = What was the average family income in 1997? $
Answers
Step-by-step explanation:
Given the function that models the income of a family as g(X) = ax+b
at x = 0, g(x) = 42000, the function becomes;
g(X) = ax+b
42000 = a(0)+b
42000 = 0+b
b = 42000
at x = 1, g(x) = 56256
56256 = a(1) + b
56256 = a+b
a = 56256 -b
a = 56256 - 42000
a = 14,256
To get the average family income in 1997, wee need to calculate g(x) at when x = 5, since the number of years between 1992 and 1997 is 5years.
g(x) = ax+b
g(5) = 14256(5) + 42000
g(5) = 71,280+42000
g(5) = 113,280
Hence the average family income in 1997 is 113,280
