Answer:
(0,8)
Step-by-step explanation:
What is needed in order to be a function?
A value of x cannot have more than one value of y. In this question, we have that for x = 0, there are 2 values of y: -2 and 8. So one of those can be removed.
Among the options, we have: (0,8), which is the correct answer

Aisha is trying to determine if △LMN and △PQR are similar, congruent, or neither using the information in the diagram.
Triangles L M N and P Q R are shown. The length of side L M is 11 and the length of P Q is 22. The length of M N is 7 and the length of Q R is 12. The length of N L is 6 and the length of R P is 12.
Which statement is true?
The statement that is true about the triangle is that D. The triangles are similar by the SSS similarity theorem.
How to illustrate the information?It should be noted that congruence simply refers to a scenario where there are the same triangles.
The SSS Similarity Theorem states that two triangles are similar if all three pairs of matching sides are proportionate.
Compare the shortest sides first, followed by the longest sides, when applying the SSS Similarity Theorem. Two triangles are similar if their corresponding side lengths are proportionate to one another.
Therefore, triangle LMN and PQR are the same.

A grocery store sells a bag of 3 oranges for $2.16. What is the cost of oranges, in dollars per orange?
Answer:
0.72
Step-by-step explanation:
The answer is that because all you have to do is just 2.16 divided by 3. Equalling to 0.72. Now we just have to do 0.72 + 0.72 + 0.72 and that would equal $2.16.

Solve the following system of equations using elimination. 2x + 5y = 12 -2x + 3y = 4
To solve a system of equation using elimination:
1. If it is necesary multyiply one of both equations for a number that makes each equation have an opposite term to the other equation.
In this case the equations already have opposite terms (2x and -2x)
2. Add equations:
3. Solve the variable in the result of substraction:
[tex]\begin{gathered} 8y=16 \\ y=\frac{16}{8} \\ \\ y=2 \end{gathered}[/tex]4. Use the value of the variable you get in the previus step to solve the other variable:
[tex]\begin{gathered} 2x+5y=12 \\ y=2 \\ \\ 2x+5(2)=12 \\ 2x+10=12 \\ 2x=12-10 \\ 2x=2 \\ x=\frac{2}{2} \\ \\ x=1 \end{gathered}[/tex]Then, the solution for the system of equations is x=1 and y=2factorize the following if possible 5z^2+35z-90
Answer:
5z² + 35z - 90 = 0

z² + 7z - 18 = 0
(z - 2)(z + 9) = 0
r=−9, s=2
STEPS USING THE DIRECT FACTORING METHOD
5z²+35z−90
This quadratic equation can be resolved using a revolutionary direct factoring technique that does not rely on guesswork. The equation must have the form x2+Bx+C=0 to be solved using the direct factoring approach. To do this, multiply both sides of the equation by 5.
x²+7x−18=0
Let r and s be the factors for the quadratic equation such that x²+Bx+C=(x−r)(x−s) where the sum of factors (r+s)=−B and the product of factors rs=C
r+s=−7
rs=−18
When the average of the two integers is 1/2*-7=-7 /2, the sum of the two numbers r and s are exactly 7. You can also observe that the parabola symbolized by the quadratic equation y=x2+Bx+C has its axis of symmetry in the middle of r and s. An unknown quantity u separates the values of r and s from the center at an equal distance. Describe r and s about the variable u.
r=−7/2−u
s=−7/2+u
Put these in the product equation rs=-18 to solve for the unknown quantity u.
(−27−u)(−27+u)=−18
Simplify by expanding (a−b)(a+b)=a2–b2
49/4−u²=−18
Simplify the expression by subtracting 49/4 on both sides
−u2=−18−49/4=−121/4
To find the value of the unknowable variable u, simplify the expression by multiplying by 1 on both sides and taking the square root.
u2=121/4
u=±√121/4=±11/2
The factors r and s are the solutions to the quadratic equation. Substitute the value of u to compute the r and s.
r=−7/2−11/2=−9
s=−7/2+11/2=2
Therefore, r=−9, s=2

Ellie wants to save her weekly allowance to go to Disneyland, In 3
weeks she has $40. In 7 weeks, she has $60. Let x represent the
number of weeks and let y represent the total amount saved. Write
an equation in slope intercept form that represents this situation
The equation in slope-intercept form that represents the situation is y = 5x + 25.
In 3 weeks Ellie she saved $40 and $60 in 7 weeks.
Let x and y represent the number of weeks and the total amount saved respectively.
The equation of a line in slope intercept form is given as:
y = mx + b where m is the slope and b is the y-intercept.
Now when x = 3, y = $40.
Therefore,
y = mx + b
40 = 3m + b --------------(1)
When x = 7, y = $60
y = mx + b
60 = 7m + b -------------(2)
Subtracting (1) from (2),
7m + b - 3m - b = 60 - 40
4m = 20
m = 5
So,
3m + b = 40
3(5) + b = 40
15 + b = 40
b = 25
Hence, the equation of the line in slope intercept form is y = 5x + 25.

Given
Angle at the top is 86
also equation 3x + 17
The lines are parallel
We know if a transverse line is drawn across two parallel lines then 3 types of angles would form namely Corresponding angle, alternate angle, Opposite angle.
From the geometry the angle 86 and the equations 3x + 17 are alternative angles.
Since alternative angles are equal 86 will be equal to 3x + 17

Choose the correct ordering of the numbers below from greatest to least.L. 779.56M. 29.7023N. 7.8695O. 0.8436P. 70.7540
When you order a number, you must check the number most in the left. The number L and the number M for example,
L. 779.56
M. 029.7023
In the hundreds place, L has a '7', and M has a '0', this means L is bigger than M.
Doing the same procedure with the other, we get the following order:

To be able to compare the weight of the boxes, we need to have their weight in decimal form:

Answer
Volume of the prism = 960 cubic units
Explanaion:
Step 1: Divide the two prism
Volume of a rectangular prism is
l x w x h
Where l = length, w= width, and h = height
The volume = full prism - cut prism
Full prism = 16 * 10 * 8

Cut prism = 8 * 10 * 4
Cut prism = 320 cubic units
Volume = 1280 - 320

8/x²+11x+28
and
-2/x^2+4x
The least common denominator of 8/( x²+11x+28 ) and -2/ (x^2+4x) is (x+4).
We have to find the least common denominator of 8/x²+11x+28 and -2/x^2+4x. We can solve this problem by following a few steps.
The denominator of both terms is, x²+11x+28 and x²+4x.
First of all, we have to find the factors of these two terms.
Let's find the factors of x²+11x+28.
x²+11x+28 = x²+11x+28
Or, x²+11x+28 = x²+ 4x+ 7x+ 28 [ we have to break the middle term in such a way as the product of consecutive terms must be 28 ]
Or, x²+11x+28 = x (x+4) +7 (x-4) [ we have to take ( x+ 4) as acommon ]
Or, x²+11x+28 = ( x+4 )( x+7 ).................(1)
Now find the factors of x²+4x.
x²+4x = x (x+4)..................(2) [ We have to take x as a common ]
Therefore, the common term between (1) and (2) is ( x+4 ). So, the least common denominator is ( x+4 ).

Answer: 1/7 = 4/28 = 8/56
Step-by-step explanation: 7 timestables
Answer:
1/7=4/28=8/56
Step-by-step explanation:
From the pattern of the question we can see that the numerator of the second fraction is 4 and the previous fraction's numerator is 1 that means the fraction has been multiplied by 4. Therefore multiplying the numerator and denominator results in the answer 4/28. For the last fraction we can see that the denominator is 56 and is the double of 28 therefore doubling the whole second fraction we get our answer as 8/56. Overall equating all the three fractions we get the same answer 1/7 after minimizing the fraction.
