Complete the remainder of the
table for the given function rule:
y = -2x + 9
please help
Answer: 17; 13; 9; 5; 1
Step-by-step explanation:
y = -2x + 9
When x = -4, y = 17
When x = -2 , y = -2x + 9 = -2(-2) + 9 = 13
When x = 0 , y = -2x + 9 = -2(0) + 9 = 9
When x = 2 , y = -2x + 9 = -2(2) + 9 = 5
When x = 4 , y = -2x + 9 = -2(4) + 9 = 1
The median of 8 numbers is 4.5.Given that seven of the numbers are 9,2,3,4,12,13,1 find the eighth number
Answer:
5
Step-by-step explanation:
Answer: 5
Step-by-step explanation:
We rerange the number in 1,2,3,4,9,12,13
The median is 4, and a number x between 4 and 9.
We have 4.5 for median, which is the average of 4 and x.
(4 + x) /2 = 4.5
4 + x = 9
x = 5

Which of these shapes is not a parallelogram? HELP ASAP 15 BRAINLY POINTS! TYSM GOD BLESS YOU AND YOUR FAMILY!
Answer:
The answer would be D____________________________________________________________
Why?
Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram. The correct answer is that all trapezoids are quadrilaterals.

A store has 125 scientific calculators.
Brand x sells for $20 each; Brand y sells
for $15 each. If the total selling price
of the calculators is $2,275, how many
of each calculator does the store have?
Answer:
Brand x: 80
Brand y: 45
Step-by-step explanation:
x + y = 125
20x + 15y = 2275
-20x - 20y = -2500
(+) 20x + 15y = 2275
--------------------------------
-5y = -225
y = 45
x + y = 125
x + 45 = 125
x = 80
Answer:
Brand x: 80
Brand y: 45
Center: (-10, -4), Point on Circle: (4, -2)
Use the information given to write an equation of the vircle.
Answer:
Step-by-step explanation:
Left hand side.
The left hand side is the general equation that includes the center of the circle.
The center is at -10,-4
(x + 10)^2 + (y + 4)^2 = r^2
Finding the radius.
the radius is found from the given point on the circle
Givens
x1 = -10
x2 = 4
y1 = - 4
y2 = - 2
Equation
r^2 = (y2 - y1)^2 + (x2 - x1)
r^2 = (-2 - - 4)^2 + (4 - - 10)^2
r^2 = 2^2 + 14^2
r^2 = 200
Note:
The graph below shows two things: the first is that the center is at -10,-4The second is that the radius is a little more than 14. The equation of a circle always expresses the radius as r^2If the data point is at (3, 10.5) and the prediction equation is y = -6.1x + 12.5, what is the value of the residual for this data point?
Given:
The data point is (3,10.5).
The prediction equation is [tex]y=-6.1x+12.5[/tex].
To find:
The value of the residual for this data point.
Step-by-step explanation:
The data point is (3,10.5). So, the actual value is 10.5 at [tex]x=3[/tex].
Prediction equation is
[tex]y=-6.1x+12.5[/tex]
Putting [tex]x=3[/tex], we get
[tex]y=-6.1(3)+12.5[/tex]
[tex]y=-18.3+12.5[/tex]
[tex]y=-5.8[/tex]
The formula for residual is:
Residual = Actual value - Expected value
[tex]Residual=10.5-(-5.8)[/tex]
[tex]Residual=10.5+5.8[/tex]
[tex]Residual=16.3[/tex]
Therefore, the residual for the given data point is 16.3.

4. Solve the equation using the quadratic formula.
4x^2+3x-10 = 0
A.x= -2, x= 1.25
B.X= -2, x= 2
C.x= -1.25, x= 2
D.x= -1.25, x= 1.25
Answer:
A. x = -2, x = 1.25
Step-by-step explanation:
Use the quadratic formula
x = [tex]\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.
4x² + 3x - 10 = 0
a = 4
b = 3
c = - 10
x = [tex]\frac{-3+\sqrt{3^{2}-4x4(-10) } }{2x4}[/tex]
Simplify
Evaluate the exponent
x = [tex]\frac{-3+\sqrt{9-4x4(-10)} }{2x4}[/tex]
Multiply the numbers
x = [tex]\frac{-3+\sqrt{9+160} }{2x4}[/tex]
Add the numbers
x = [tex]\frac{-3+\sqrt{169} }{2x4}[/tex]
Evaluate the square root
x = [tex]\frac{-3+13}{2x4}[/tex]
Multiply the numbers
x = [tex]\frac{-3+13}{8}[/tex]
Separate the equations
To solve for the unknown variable, separate into two equations: one with a plus and the other with a minus.
x = [tex]\frac{-3+13}{8}[/tex]
x = [tex]\frac{-3-13}{8}[/tex]
Solve
Rearrange and isolate the variable to find each solution
x = - 2
x = 1.25
Answer:
A. x = -2, x = 1.25
Step-by-step explanation:
Use the sum-product pattern
4x² + 3x - 10 = 0
4x² + 8x - 5x - 10 = 0
Common factor from the two pairs
(4x² + 8x) + (-5x - 10) = 0
4x (x + 2) - 5 (x + 2) = 0
Rewrite in factored form
4x (x + 2) - 5 (x + 2) = 0
(4x - 5)(x + 2) = 0
Create separate equations
(4x - 5)(x + 2) = 0
4x - 5 = 0
x + 2 = 0
Solve
Rearrange and isolate the variable to find each solution
x = 1.25
x = - 2
Write an equation of the line that passes through the point (4, 14) and is parallel to the line whose equation is y=3x-7.
Answer:
y = 3x + 2
Step-by-step explanation:
If the line is parallel, then the slope remains the same.
To find the y-intercept, just plug the coordinates into the equation
y = 3x + b
14 = 3(4) + b
14 = 12 + b
2 = b
The equation is y = 3x + 2
Answer:
Slope intercept form
y=3x^2−19x+42
or
Point slope form
y−14=(3x−7)⋅(x−4)
