Answer: For following equation x = 7 not a solution:
-5 = 2x-9
Answer:
Step-by-step explanation:
Put x to the equation.
4=-7+11 => 4=4 ✓
-3•7=7-28 =>-21=-21 ✓
-5•7= 2•7-9 =>-35=5 is incorrect.
5•7=2•7+21 =>35=35 ✓
Hence,for the third equation x is not a solution.

Ms. Rowlen went Black Friday shopping and she bought a flat screen TV that originally costs $259.00. She used her super Savings Coupon of 45%, how much did Ms. Rowlen pay for the TV?
If she used a coupon of 45%, the price markdown would be 116.55. You must subtract the markdown from the original cost to discover the amount she had to spend.
259.00 - 116.55 = 142.45
So, Ms Rowlen had to spend 142.45 on the TV.

Answer:
11.8 meters
Step-by-step explanation:
The triangle drawn is a right triangle. Two of its side lengths are given. The Pythagorean theorem tells you how those relate to the third side.
The sum of the squares of the legs of the triangle is equal to the square of it hypotenuse.
(?)² + 34² = 36²
(?)² + 1156 = 1296 . . . evaluate the squares
(?)² = 140 . . . . . . . . . . subtract 1156 from both sides
(?) = √140 . . . . . . . . . take the square root
(?) ≈ 11.8 . . . meters
The length of the shadow is about 11.8 meters.

Step-by-step explanation:
I don't know the options to pick from.
the 2 main possibilities coming to my mind are
y = f(x)
or
(x, f(x)) or (x, y)
there is no specific function coming to mind. the functional values bounce around above and below the x-axis (positive and negative y-values) with not detectable pattern related to the x values.
the other 2 questions can be found directly in the table :
f(3) means f(x) with x=3, and that is -2
and f(x) = -5 is true, when x = 4

Write the equation of a line that goes through the points (-5,6) and (10,-6). The final answer should be in Slope Intercept Form.
Answer:
y=-4/5x+2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-6-6)/(10-(-5))
m=-12/(10+5)
m=-12/15
simplify
m=-4/5
y-y1=m(x-x1)
y-6=-4/5(x-(-5))
y-6=-4/5(x+5)
y=-4/5x-20/5+6
y=-4/5x-4+6
y=-4/5x+2
The oblique prism below has an isosceles right triangle base.
An oblique right triangular prism is shown. The triangular bases have 2 sides with a length of x. The length of they hypotenuse is unknown. The distance from the 2 triangular bases is (x + 3). The vertical height of the prism is (x + 2).
What expression represents the volume of the prism, in cubic units?
One-halfx3 + x2
One-halfx3 + Three-halves x2
x3 + x2
x3 + 3x2
The volume of the prism, in cubic units is 1/2x³ + x²
The volume of the oblique prism is given as:
V = Base area * Height
Given the following
Height = x + 2Base area = area of the triangleBase area = 1/2 (x*x)
Base area = 1/2 x²
Get the volume of the prism;
Volume of the prism = 1/2(x²)(x+2)
Volume of the prism = 1/2(x³+2x²)
Volume of the prism = 1/2x³ + 1/2(2x²)
Volume of the prism = 1/2x³ + x²
Hence the volume of the prism, in cubic units is 1/2x³ + x²

Answer:
sqrt( 74)
8.602
Step-by-step explanation:
To find the distance between the two points we use the formula
d = sqrt( ( x2-x1)^2 +(y2-y1)^2)
= sqrt( ( 3- -2)^2 + ( -2 -5)^2)
= sqrt( (3+2)^2 + ( -7)^2)
= sqrt( 5^2 (-7)^2)
= sqrt( 25+49)
= sqrt( 74)

Answer: 44 ft
Step-by-step explanation:
if you add up the right square it adds up to 16 4+4+4+4 all sides are equal since its a square.
The left rectangle is
8+8=16
6+6=12
16+12=28
Now you add the square on the right to the square on the left which is
28+16= 44 ft
What is the slope of the line that passes through the points (5, 6)(5,6) and (5, 9) ?(5,9)? Write your answer in simplest form.
Answer:
Step-by-step explanation:
Slope is defined as the "Rise" over the "Run" of a straight line. The Rise is the change in y, and the Run is the change in x. For the given points:
(5,6) and (5,9) the Rise and Run are (going from left to right).
Rise (9-6) = 3
Run = (5-5) = 0
The slope is 3/0, which is undefined (can't divide by zero).
Solve for x

Use midpoint theorem :- The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also 'half of the length of the third side'.
So,
2x - 6 = ½ (3x - 6)
2x - 6 = 3x/2 - 3
2x - 3x/2 = -3 + 6
½ x = 3
x = 3 × 2
x = 6

Number of Hours
Total Earning (in dollars)
(4 , 90)
The unit rate is 4 hours per dollar
The unit rate is 22.5 hours per dollar
The unit rate is $90.00 per hour
The unit rate is $22.50 per hour
The statement that is true about the graph as it relates the unit rate is:
d. The unit rate is $22.50 per hour
How to find Unit RateUnit rate of a relationship between two variables, x and y, that are proportionally related can be found using k = y/x, where k is the unit rate.
Given that:
x = hours he worked
y = his total earnings
We are told that (4, 90) is a point on the graph.
Using the point, (4, 90), we can find the unit rate as shown below:
k = y/x = 90/4
k = 22.5
Therefore, the statement that is true about the graph as it relates the unit rate is:
d. The unit rate is $22.50 per hour

Which of the following is equivalent to:
−−(2+5)−(3−7)?
Answer:
You haven't provided expressions, so I can work out the problem for you. When we divide fractions, remember always "keep, switch, flip!" That's what we're gonna do here. We keep the 2/5, switch the sign to multiplication, and flip the 7/8 to 8/7. Therefore, we have 2/5*8/7. That gives us 16/35. Hope this helps!
