Some number decreased by seven is thirty-three. x - 7 = 33
A number increased by twelve is forty. x + 12 = 40
A number increased by fifteen is sixty-two. x + 15 = 62
Eight less than a number is nine. x - 8 = 9
A number divided by 11 is 4. x/11 = 4
Seven more than three times a number is 19. 3x + 7 = 19
Four more than five times a number is thirty-six. 5x + 4 = 35
Eight less than nine times a number is eleven. 9x - 8 = 11
Twelve more than four times a number is seven. 4x + 12 = 7
Seven more than triple a number is fifteen. 3x + 7 = 15
Seven times a number increased by eight equals twenty-three. 7x + 8 = 23
Eight more than six times a numbers is eleven. 6x + 8 = 11

A linear regression equation is computed for a sample of n = 13 pairs of X and Y scores. For the analysis of regression testing the significance of the equation, what are the df values for the F-ratio?
Answer:
The degrees of freedom are
ν₁ = n₁ -1 = 13 -1 = 12
ν₂= n₂-1 = 13 -1 =12
Step-by-step explanation:
Step(i):-
Given size 'n' = 13
size of sample of X score n₁ = 13
size of sample of Y score n₂ = 13
The degrees of freedom are
ν₁ = n₁ -1 = 13 -1 = 12
ν₂= n₂-1 = 13 -1 =12

3x+2y=-3
3x-y=6
Group of answer choices
(-1, 0)
(1, -3)
(2, 0)
LaTeX: (0,-\frac{3}{2})
Answer:
(1, -3) is a solution to the system of equations ⇒ B
Step-by-step explanation:
Let us solve the system of equations
∵ 3x + 2y = -3 ⇒ (1)
∵ 3x - y = 6 ⇒ (2)
→ Subtract equation (2) from equation (1)
∵ (3x - 3x) + (2y - -y) = (-3 - 6)
∴ (0) + (2y + y) = (-9)
∴ 3y = -9
→ Divide both sides by 3 to find y
∴ y = -3
→ Substitute the value of y in equation (2) to find x
∵ 3x - (-3) = 6
∴ 3x + 3 = 6
→ Subtract 3 from both sides
∵ 3x + 3 - 3 = 6 - 3
∴ 3x = 3
→ Divide both sides by 3 to find x
∴ x = 1
To check the answer substitute the values of x any in each equation if the two sides of the equation are equal, then the solution is right
∵ 3x + 2y = -3
∵ 3(1) + 2(-3) = -3
∴ 3 - 6 = -3
∴ -3 = -3
→ The two sides of the equation are equal
∵ 3x - y = 6
∵ 3(1) - (-3) = 6
∴ 3 + 3 = 6
∴ 6 = 6
→ The two sides of the equation are equal
∴ The solution satisfies the two equations
∴ (1, -3) is a solution to the system

Polygon MNP shown on the coordinate planeA dilation centered about the origin will be performed on the polygon with vertices M(- 18, 12) forall(8,10),8(-6,8) and Q(- 8, - 8)
Answer:
N'(4, 5)
Step-by-step explanation:
The correct question is attached.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation.
Dilation is a transformation that changes the size of a figure (i.e. it increases or reduces the size).
If a point A(x, y) is dilated by a factor k, the new point is at A'(kx, ky).
The location of the polygon vertex is at M(-16, 12), N(8, 10), P(-6, 8) and Q(-8, -8).
After dilation, the new location of M is at M'(-8, 6)
M(-16, 12) ⇒ M'(-8, 6)
M(-16, 12) ⇒ M'[1/2(-16), 1/2(12)]
Hence the dilation factor is 1/2. This means that the new vertex is at:
N'(4, 5), P'(-3, 4) and Q'(-4, -4).
Evaluate 4 cubed. I will mark brainlest.
Answer:
64
Step-by-step explanation:
4 cubed is 64 because 4 cubed can be written as an exponentiation, where the base is 4 and the exponent is 3, like this: 43. For future reference, note that cubed means that the exponent is 3 regardless of what the base is. When the exponent is 3 (aka cubed) and the base is 4 you simply multiply 4 by 4 by 4 to get the answer 64
Find the value of x and y
Answer:
x=45 degrees
y=45 degrees
Step-by-step explanation:
Answer: y = 50; x = 34
ABCD is a quadrilateral inscribed in the circle
=> ∠ABD = ∠ACD
⇔ x = 34°
and ∠ADB = ∠ACB
we also have:
∠DCE + ∠ DCB = 180°
⇔ 96° + x + ∠ACB = 180°
⇔ ∠ACB = 180 - 96 - x = 180 - 96 - 34 = 50
because ∠ADB = ∠ACB => y = 50°
Step-by-step explanation:
How many solutions does the equation below have.
*The answer choices are below*
==========================================
Work Shown:
2(b+3)-17 = 3b-7+b
2b+6-17 = 4b-7
2b-11 = 4b-7
-11+7 = 4b-2b
-4 = 2b
2b = -4
b = -4/2
b = -2
There is one solution and it is b = -2
A quick way to tell we have one solution is to note that both sides are a linear expression, and that the slopes of each linear expression are different values. If you had two lines with the same slope, then you'd have either parallel lines or coinciding lines (leading to no solutions and infinitely many solutions respectively). When you have two lines with two different slopes, then they are guaranteed to intersect only once. That intersection point is the solution.
Answer:
The answer is one solution
Step-by-step explanation:
1)2(b+3)-17 = 3b-7+b
2)2b+6-17 = 4b-7
3)2b-11 = 4b-7
4)-11+7 = 4b-2b
5)-4 = 2b
6)2b = -4
7)b = -4/2
Final your answer is b = -2

Step-by-step explanation:
So find 5*6 first aAnd you’d get 30
30*2 becuase there are 2 sides, 60
10*6 is 60
60*2 is 120
5*10 is 50
50*2 is 100
now add them all up

The shoes were $175. They are now 10% off. How much are they now?
Sale Price = $157.5 (answer). This means the cost of the item to you is $157.5. You will pay $157.5 for a item with original price of $175 when discounted 10%. In this example, if you buy an item at $175 with 10% discount, you will pay 175 - 17.5 = 157.50 dollars.

Answer:
-4
Step-by-step explanation:
Alexus is modeling the growth of bacteria for an experiment in science. She assumes that there are B bacteria in a Petri dish at 12:00 noon. In reality, each bacterium in the Petri dish subdivides into two new bacteria approximately every 20 minutes. However, for the purposes of the model, Alexus assumes that each bacterium subdivides into two new bacteria exactly every 20 minutes.
2a. Create a table that shows the total number of bacteria in the Petri dish at 1/3 hour intervals for 2 hours starting with time 0 to represent 12:00 noon.
2b. Write an equation that describes the relationship between total number of bacteria T and time h in hours, assuming there are B bacteria in the Petri dish at h=0.
2c.If Alexus starts with 100 bacteria in the Petri dish, draw a graph that displays the total number of bacteria with respect to time from 12:00 noon (h=0) to 4:00 p.m. (h=4). Label points on your graph at time h=0,1,2,3,4.
2d. For her experiment, Alexus plans to add an anti-bacterial chemical to the Petri dish at 4:00 p.m. that is supposed to kill 99.9% of the bacteria instantaneously. If she started with 100 bacteria at 12:00 noon, how many live bacteria might Alexus expect to find in the Petri dish right after she adds the anti-bacterial chemical?
