Answer:
B
Step-by-step explanation:
Given
x² - 6x - 14 = 0 ( add 14 to both sides )
x² - 6x = 14
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 3)x + 9 = 14 + 9
(x - 3)² = 23 → B

Which congruence theorems can be used to prove AABR = AACR? Select three options.
A. HL
B. AS
C. SSS
D. ASA
E. AAS
Answers
Answers:
A) HL
B) SAS (I'm assuming you meant to say SAS instead of AS)
C) SSS
========================================================
Explanation:
The square angle marker tells us we have 90 degree angles. So these are right triangles.
Because we're dealing with right triangles, we could use HL which stands for "hypotenuse leg". The hypotenuse is AR for either triangle, and you could use either of these two pairs for the leg
AB = AC (one possible pairing), or,BR = CR (another possible leg pairing)-----------------------
The tickmarks tell us which sides are the same length. We can see that
AB = AC (single tickmark)BR = CR (double tickmarks)We also know that angle ABC = angle ACR because all right angles are congruent. These facts allow us to use SAS (side angle side). I'm assuming you meant to say "SAS" instead of "AS" for choice B.
-----------------------
SSS stands for "Side Side Side". It means if we know that three pairs of sides are congruent, then we can prove the triangles congruent overall.
The three pairs of congruent sides are:
AB = AC (single tickmark)BR = CR (double tickmarks)AR = AR (shared overlapped side; reflexive property)-----------------------
Side notes:
We can rule choice D out because we don't have enough info to use ASA. We would need info about another pair of congruent angles.Similarly, AAS can't be used either. We only have info about one pair of angles (not two). So we can rule out choice E.What is the slope and y-intercept of the equation 8x +

Answers
Answer:
SLOPE = - 4
y-intercept = 9
Step-by-step explanation:
Slope = - 8/2 = - 4
Y-INTERCEPT = 18/2 = 9
The y intercept would be 9 and the slope would be -4
Explanation:
8x+2y=18
-8x -8x
2y= -8x+18
2y/2= -8x/2+18/2
y=-4x+9
So you would basically subtract 8x on both sides then divide by 2. I hope this helped!

1). f(x) = 2x
f(-3) = 2(-3) = -6
f(1) = 2(1) = 2
f(4) = 2(4) = 8
Ordered pairs → (-3, -6), (1, 2), (4, 8)
2). f(x) = 2x + 1
f(-3) = 2(-3) + 1 = -5
f(1) = 2(1) + 1 = 3
f(4) = 2(4) + 1 = 9
Ordered pairs → (-3, -5), (1, 3) and (4, 9)
x -3 1 4
f(x) -5 3 9
3). f(x) = -3x
f(-3) = -3(-3) = 9
f(1) = -3(1) = -3

Sum of Functions
We are given the functions for the cost of two generators:
[tex]C(x) = 0.03x^2+26x+24[/tex]
[tex]K(x) = 0.01x^2+38x+118[/tex]
We are required to find the function for the sum of the costs of the two generators:
T(x)= C(x)+K(x)
We'll add both functions:
[tex]T(x)= 0.03x^2+26x+24+ 0.01x^2+38x+118[/tex]
To find the sum of both functions, we collect like terms:
[tex]T(x)= (0.03+0.01)x^2+(26+38)x+(24+118)[/tex]

Ellie and Jamie like to bake cookies. Ellie baked 24 chocolate chip cookies, and Jamie baked p peanut butter cookies. Together they baked a total of 56 cookies. Write an equation that can be solved for p to find the number of cookies Jamie baked? A) 24/p = 56 B) p - 24 = 56 C) p + 24 = 56 B) 24p = 56
Answers
Answer:
C) p + 24 = 56
Step-by-step explanation:
The total number of cookies baked = Number of cookies Ellie baked + Number of cookies Jamie baked
Ellie baked 24 chocolate chip cookies.
Jamie baked p peanut butter cookies.
Total of 56 cookies.
Hence:
56 = p + 24
Therefore, the equation that can be solved for p to find the number of cookies Jamie baked is
p + 24 = 56

Which answer best describes the system of equations shown in the graph?
Inconsistent
Consistent and independent
Consistent and dependent
Answers
Answer:
we conclude that the given system of equations is consistent and independent.
Hence, option B is true.
Step-by-step explanation:
From the figure it is clear that the two lines intersect at one point.
In other words, there is only one point of intersection of the given system of equations.
It means the system of equations contains exactly one solution.
We know that If a consistent system contains exactly one solution, it is termed as an independent.
Therefore, we conclude that the given system of equations is consistent and independent.
Hence, option B is true.

5.Footlocker buys Air Jordans for $30 a pair. They mark it up 75%. How much is the mark-up on a pair of Air Jordans
If you buy a pair of Air Jordans as mentioned in question #5, how much would you end up paying? (Hint: original amount + mark-up amount)
Answers
Answer:
$52.50
Step-by-step explanation:
What you do is you move the decimal two times to the left from 75%.
0.75*?=?
Take the orginal price and multiply ($30) by 0.75.
0.75*30= $22.50
Take 22.50 and add that to your original amount.
$22.50+$30= $52.50 or $52.5

Answers
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation, and translation.
Translation is the movement of a figure up, down, left or right.
Dilation is the enlargement or reduction in the size of a figure by a factor.
Reflection is the flipping of a figure about a point.
Rotation is the turning of an image about a fixed point.
From the image attached, triangle A was dilated (reduced) to produce triangle B.

For each sequence find the first four terms and the tenth term 3n-4
Answers
Answer:
= 1, 2, 5, 8 and 26
Step-by-step explanation:
To find the first 4 terms, substitute n = 1, 2, 3, 4 into the formula
a₁ = 3(1) - 4 = 3 - 4 = - 1
a₂ = 3(2) - 4 = 6 - 4 = 2
a₃ = 3(3) - 4 = 9 - 4 = 5
a₄ = 3(4) - 4 = 12 - 4 = 8
The first 4 terms are
- 1, 2, 5, 8
Substitute n = 10
a₁₀ = 3(10) - 4 = 30 - 4 = 26
Answer:
Below.
Step-by-step explanation:
We get the first 4 terms by plugging in n = 1 2 3 and 4:
3(1) - 4 = -1 , 3(2) - 4 = 2 ...
First 4 terms are
-1, 2, 5, 8
10th term = 3(10) -4 = 26.
