Answer:
One way to solve the quadratic equation x2 = 9 is to subtract 9 from both sides to get one side equal to 0: x2 – 9 = 0. The expression on the left can be factored:
(x + 3)(x – 3) = 0. Using the zero factor property, you know this means x + 3 = 0 or x – 3 = 0, so x = −3 or 3

x^9=12^2x12^7
Answer:
12Step-by-step explanation:
Hi!
Here is your answer,
I will explain in step by step,
[tex] {x}^{9} = {12}^{2} \times {12}^{7} [/tex]
Here we can simplify this further using this law,
[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]
So we will get,
[tex] {x}^{9} = {12}^{7 + 2} \\ {x}^{9} = {12}^{9} [/tex]
Since the powers are same we can cancel it out and we will get,
[tex]x = 12[/tex]

On a soccer team there are 5 sixth graders. 9 seventh graders, and eight eighth graders. What percent of the car is sixth graders?
Answer:
22.72 %
Step-by-step explanation:
There are 5 sixth graders over a total of 5+8+9 = 22 students. Therefore the percent of sixth graders would be:
5/22 * 100 ≈ 22.72 %

Quadrilateral MNPQ is shown on the grid below.
What is the area, in square units, of the quadrilateral?
A) 182 square units
B) 4550 square units
C) 9100 square units
D) 91 square units
Answer:
42 square units
Step-by-step explanation:
Find the diagram attached
Area of the diagram = Area of the triangle + Area of rectangle
Area of rectangle = Length * Width
Area of rectangle = 3 * 6
Area of rectangle = 18 square units
Area of triangle = 1/2 * base * height
Get the base of the tringle using the pythagoras theorem;
b^2 = 10^2-6^2
b^2 = 100 - 36
b^2 = 64
b = 8units
height = 6 units
Area of the triangle = 1/2 * 8 * 6
Area of the triangle = 48/2
Area of the triangle = 24 square units
Area of the figure = 18+24
Area of the figure = 42 square units
What does the discriminant determine?
Which number is in the solution set of this equation? 7x − 9 = 40
Answer: the answer is 7
Step-by-step explanation: add 9 to both sides, eliminating -9 so now you have 7x=49 divide both by 7 and you get x= 7 check it by inputing 7 for x, 7(7)-9=40
7(7)=49 next 49-9= 40
it checks out, so x= 7

A toy manufacturer is shipping its newest product, an interactive talking globe, to a major toy store. The packaging for the globe is a rectangular prism that measures 2512 2512 inches high, 18 inches long, and 18 inches wide. The boxes for the globes are packaged into shipping crates that hold 8 globes each. What is the minimum volume of one shipping crate? Explain your answer in the space provided.
Answer:
6 511 104 in³
Step-by-step explanation:
Since we have 1 crate and 8 boxes fit into one crate.
So, volume of one crate, V' = 8 × volume of 1 box, V
Since the box is a rectangular prism of sides 2512 inches high, 18 inches long, and 18 inches wide, its volume, V = lwh where l = length of prism, h = height of prism and w = width of prism.
So, V = lwh = 18 in × 18 in × 2512 in = 813 888 in³
So, V' = 8 × 813 888 in³ = 6 511 104 in³
So, the minimum volume of the crate is 6 511 104 in³

which ordered pair represents the points at which line r and line s intersect?
A. (1.5 , 0.5)
B. (9.375 , 38.75)
C. (12.5 , 23.75)
D. (15, 27.5)
Answer:
C. (12.5 , 23.75)
Step-by-step explanation:
Find the distance between (2, 9) & (-1, 4). Round to the nearest tenth.
Answer:
1.7
Step-by-step explanation:
To find the distance between two coordinates, use the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex].
y2 = 4, y1 = 9, x2 = -1, x1 = 2
Insert the values into the equation:
[tex]\frac{4-9}{-1-2}[/tex]
Simplify:
[tex]\frac{4-9}{-1-2}= \frac{-5}{-3}=\frac{5}{3}[/tex][tex]\frac{}{} =1.7[/tex]
The distance between (2, 9) and (-1, 4), rounded to the nearest 10th, is 1.7.

A test has 25 true/false questions. If 64% of the answers are true, how many of the test questions are true?
Answer:
16
Step-by-step explanation:
First, let's find 64% of 25. We do this and get:
[tex]\frac{64}{100}\cdot25=\frac{1600}{100}=16. \text{ so our answer is \boxed{16 \text{ problems are true}}}[/tex]
A square painting has a side length of 13 inches.
What is the area of the painting?
Answer:
169
Step-by-step explanation:
13*13=169
Answer:
169
Step-by-step explanation:
length x width = area
since it is a square, all sides are equal.
13 x 13 = 169

-6x+5y=1
6x+4y=-10
what is the answer to this problem by elimination
Answer:
x= -1 and y= -1
Step-by-step explanation:
Answer:
(-1,-1)
Step-by-step explanation:
-6x+5y=1
6x+4y=-10
Add the two equations together to eliminate x
-6x+5y=1
6x+4y=-10
---------------------
9y = -9
Divide by 9
9y/9 = -9/9
y= -1
Substitute back into one of the equations to find x
-6x+5y=1
-6x +5(-1) = 1
-6x -5 = 1
Add 5 to each side
-6x -5+5 = 1+5
-6x = 6
Divide by -6
-6x/-6 = 6/-6
x = -1
(-1,-1)

Is 9/10, 1 1/5, 1 1/2 a right triangle?
Answer:
using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2
a²+b²=c²
(9/10)²+(11/5)²=(11/2)²
81/100+121/25=121/4
lcm of 25 and 100 =100
(81+484)/100=121/4
565/100=121/4
113/20=121/4
since they are not equal therefore it's not a right angle triangle
