Step-by-step explanation:
I imagine you plug in the given ordered pair to the rule:
( x - 3, y + 9 )
( 2 - 3, 12 + 9 ) ( - is the same as going to the right, so it basically adds ).
( + is the same as going to the right, so it basically subtracts ).

Jerry's mother is 36 years old and she is eleven less than four times Jerry's age.how old is Jerry?
Answer:
Jerry is 11.75 years
Step-by-step explanation:
Let us first set up an equation
Let jerry's age be x
4x - 11 = 36 (equation set)
Now we need to slove the equation and find the value of x that is Jerry's age
4x - 11 = 36
Transpose
4x = 36 + 11
4x = 47
x = 47 ÷ 4
x = 11.75 years
Jerry is 11.75 years
Geometry please help ASAP
Answer:
D) 22
Step-by-step explanation:
B is the midpoint. The midpoint is the point in a line that breaks the line into two equal segments. With that info, we know that BC = AC.
So that means:
3x - 14 = x + 10
Now solve this equation.
3x - 14 = x + 10
+14. +14
3x = x + 24
-x
2x = 24
/2. /2
X = 12.
Now we know the value of x, insert the value into x + 10.
12 + 10 = 22
The answer is 22
Answer:
B) 12
Step-by-step explanation:
Because,
3x - 14 = x + 10
3x - x = 10 + 14
2x = 24
x = 12

Write the equation of the line that passes through the points (2,-2)( and (−9,9). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
using the formula( y2-y1/x2-x1 = m)
m= slope
9 - (-2)/-9 -2 =m
11/ -11 = m
m= -1( slope)
since m is also = y- y1/ x-x1
y - (-2)/ x- 2 = -1= y +2 / x -2 = -1 (cross multipy)
-1 (x -2) = y +2
-x +2 = y + 2
-x -y = 2 -2
-x - y = 0(multiply both sides by -1)
x + y = 0

Christine can type 63 words in 9 minutes. What is her rate in words per minute?
Answer:
7 words per minute
Step-by-step explanation:
63 words = 9 mins
9 mins = 63 words
1 min = 63 words/9
1 min = 7
She can type 7 words per minute
-Chetan K
Answer:
7 words per minute
Step-by-step explanation:
1. To find the unit rate (words per minutes), let's set up two ratios:
63:9 = x:1 or 63/9 = x/12. Now, let's solve for x to find how many words she can type per minute.
Step 1: Cross-multiply.
[tex]9 * x = 63 * 1[/tex] [tex]9x = 63[/tex]Step 2: Divide both sides by 9.
[tex]\frac{9x}{9} = \frac{63}{9}[/tex] [tex]x = 7[/tex]Therefore, Christine can type 7 words per minute.

Write an equation for a parabola with x-intercepts (-4,0) and (2,0) which passes through the point (1,-10).
Answer:
y=2x^2+4x−16
Step-by-step explanation:
Assume that the equation of the parabola is y=ax2+bx+c.
Since the parabola passes through the point (−4,0), then 0=16a−4b+c.
Since the parabola passes through the point (2,0), then 0=4a+2b+c.
Since the parabola passes through the point (1,−10), then −10=a+b+c. Thus, we have obtained the following system:
{16a−4b+c=0; 4a+2b+c=0; a+b+c=−10Solving it, we get that a=2, b=4, c=−16. Thus, the equation of the parabola is y=2x^2+4x−16.
The equation of a parabola is y = -x² + x + 4 with x-intercepts at (-4,0) and (2,0) that passes through the point (1,-10).
What is the equation for a parabola?A parabola can be represented by the equation:
y = ax² + bx + c
To find the equation of a parabola that has x-intercepts at (-4,0) and (2,0), we can set y equal to 0 and solve for x to find the x-intercepts:
0 = a(-4)² + b(-4) + c
0 = a(2)² + b(2) + c
Solving these equations for a and c gives us:
c = b(-4)
c = -2b
The parabola passes through the point (1,-10), we can substitute the values of x and y into the equation to solve for b:
-10 = a(1)² + b(1) + (-2b)
-10 = a + b - 2b
-10 = a - b
Substituting c = b(-4) into the equation gives us:
y = a x² + b x + b(-4)
Substituting a = -b and solving for b gives us:
y = (-b) x² + b x + b(-4)
y = -b(x² - x - 4)
Since the x-intercepts are at (-4,0) and (2,0), the coefficient of x², which is -b, must be positive. Therefore, we can set b = 1 to get the equation of the parabola:
y = -(1)(x² - x - 4)
y = -x² + x + 4
Thus, the equation of a parabola is y = -x² + x + 4.

Find value of Y
Answer:
y = 50
Step-by-step explanation:
This requires the alternate interior angle theorem, which states that:
The alternate interior angle theorem states that if two parallel lines are cut by a transversal, then alternate interior angles are congruent.
Since 50 degrees is an alternate interior angle to y, y must be equal to 50 degrees.
So,
y = 50
