Answer:
2 - (-4)
4 + (-2)
5 - (-5)
6 - (-1)
Step-by-step explanation:
- 1 + (-5) = -1 - 5 = -6
2 - (-4) = 2 + 4 = 6
-3 + 2 = -1
4 + (-2) = 4 - 2 = 2
5 - (-5) = 5 + 5 = 10
6 - (-1) = 6 + 1 = 7
Help!Write the equation in slope- intercept form of the line that passes through (−1, 11) and is parallel to the graph of y = −8x − 2
Answer:
y = -8x + 3
Step-by-step explanation:
plug in the point and the slope into the slope intercept formula (y=mx+b)
the slope will be the same since you want the line to be parallel
11 = -8(-1) +b now solve for b
11 = 8 + b
-8 -8
3 = b
now write the equation with only the slope and the y intercept
y = -8x + 3
The equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.
What is the slope intercept form of a line?The slope intercept form of a line is given by -
y = mx + c
m is the slope of line
c is the y - intercept
Given is a line that passes through (-1, 11) and is parallel to the line -
y = − 8x − 2.
Since, the line is parallel to the line → y = − 8x − 2, therefore, their slope will be same and is equal to m = - 8.
Now, in the slope intercept form, assume that the equation of line looks like -
y = - 8x + c
Now, the line passes through the point (-1, 11), we can write -
11 = -8 x -1 + c
11 - 8 = c
c = 3
Hence, we can write the equation of the line as -
y = - 8x + 3
Therefore, the equation of a line that passes through (-1, 11) and is parallel to the line y = - 8x + c is y = - 8x + 3.

Step-by-step explanation:
a. 5% of $788,116 = $39,405.80
b. 75% of $32 = $24
c. John's earnings = $6.25 * 14 = $87.50
Taxes = 18%; therefore, take home = 82% (100 - 18)
He will keep 82% of $87.50 = $71.75
d. Population in 1980 = 95% of 4,800 = 4,560
e. 45% of 452 = 203
f. Mrs Eversole will pay $250 * 0.07 = $17.50
g. 36% of 500 = 180
h. 80% of $350 = $280
i. Actual height = 37.8/135 * 100 = 28 ft
j. If 41% = 294, then 100% = 294/41 * 100 = 717
k. Manuel's total collection = 42/12.5% * 100% = 336

m. If 56% = 14, then Wanda shot 14/56% * 100% = 25
n. Newmark to Briton will be 160/85% * 100 = 188 miles
o. If 80% = 24, then the number of questions = 24/80% * 100 = 30
p. Anfernee missed 36 shots = 19% (36/191 * 100)
q. 36/225 * 100 = 16%

Tangent Property
Solve the following problems. Remember that all reasoning must be explained, and all steps of math work must be shown!
Answer:
see below
Step-by-step explanation:
1) Length of side OQ can be solved by using Pythagorean
OQ² = 3² + 4²
= √25
= 5
2) Length of side PQ can be solved by using Pythagorean
13² = 5² + PQ²
PQ² = 13² - 5²
= √144
= 12
3) Length of side RS and SQ can be solved by using Pythagorean
RS² = 13² - 6²
= √133
= 11.5
SQ² = 8² - 6²
= √28
= 5.3
9514 1404 393
Answer:
OQ = 5.0PQ = 12.0RS = 11.5, SQ = 5.3Step-by-step explanation:
A tangent meets the radius at right angles at the point of tangency. The triangles here are all right triangles, so the Pythagorean theorem can be used to find the missing side lengths.
__
1. a² = 3² +4² = 25
a = √25 = 5 = OQ
__
2. 5² +a² = 13²
a² = 13² -5² = 144
a = √144 = 12 = PQ
__
3. a = √(13² -6²) = √133 ≈ 11.5 = RS
b = √(8² -6²) = √28 ≈ 5.3 = SQ

Select the correct answer. If A= and Ab= what is the value of matrix b
Answer: C. [tex]B=\left[\begin{array}{ccc}1\\3\\-5\end{array}\right][/tex]
Step-by-step explanation: I got this right on Edmentum.
Several operations such as addition, subtraction, multiplication, etc. can be performed on matrices. The value of matrix B is:
[tex]B =\left[\begin{array}{c}1&3&-5\end{array}\right][/tex]
Given that:
[tex]A =\left[\begin{array}{ccc}2&4&-2\\4&-5&7\\2&7&5\end{array}\right][/tex]
[tex]AB =\left[\begin{array}{c}24&-46&-2\end{array}\right][/tex]
Let matrix B be:
[tex]B =\left[\begin{array}{c}a&b&c\end{array}\right][/tex]
The product of A and B is as follows:
[tex]\left[\begin{array}{ccc}2&4&-2\\4&-5&7\\2&7&5\end{array}\right] \times\left[\begin{array}{c}a&b&c\end{array}\right][/tex]
Multiply the rows of A to the column of B. So, we have:
[tex]AB =\left[\begin{array}{ccc}2a+4b-2c\\4a-5b+7c\\2a+7b+5c\end{array}\right][/tex]
This means that:
[tex]\left[\begin{array}{ccc}2a+4b-2c\\4a-5b+7c\\2a+7b+5c\end{array}\right] = \left[\begin{array}{c}24&-46&-2\end{array}\right][/tex]
By comparison, we have:
[tex]2a + 4b - 2c = 24[/tex] --- (1)
[tex]4a - 5b + 7c = -46[/tex] --- (2)
[tex]2a + 7b + 5c = -2[/tex] --- (3)
Multiply (1) and (3) by 2
[tex]2a + 4b - 2c = 24[/tex] --- (1)
[tex]4a + 8b - 4c = 48[/tex] ----- (5)
[tex]2a + 7b + 5c = -2[/tex] --- (3)
[tex]4a + 14b + 10c = -4[/tex] ---- (6)
So, we have:
[tex]4a - 5b + 7c = -46[/tex] --- (2)
[tex]4a + 8b - 4c = 48[/tex] ----- (5)
[tex]4a + 14b + 10c = -4[/tex] ---- (6)
Make 4a the subject in each of the equations
[tex]4a = -46 + 5b - 7c[/tex]
[tex]4a = 48 - 8b + 4c[/tex]
[tex]4a = -4 - 14b - 10c[/tex]
[tex]4a = 4a[/tex]. So, we have:
[tex]-46 + 5b - 7c = 48 - 8b + 4c[/tex] and [tex]-46 + 5b - 7c = -4 - 14b - 10c[/tex]
Simplify both expressions
[tex]-46 + 5b - 7c = 48 - 8b + 4c[/tex]
[tex]5b + 8b - 7c - 4c = 48 + 46[/tex]
[tex]13b - 11c = 94[/tex]
[tex]-46 + 5b - 7c = -4 - 14b - 10c[/tex]
[tex]5b+14b - 7c + 10c = 46-4[/tex]
[tex]19b + 3c = 42[/tex]
Make c the subject
[tex]c = \frac{42 -19b}{3}[/tex]
Substitute [tex]c = \frac{42 -19b}{3}[/tex] in [tex]13b - 11c = 94[/tex]
[tex]13b - 11 \times (\frac{42 - 19b}{3}) = 94[/tex]
Multiply through by 3
[tex]39b - 11 \times (42 - 19b) = 282[/tex]
Open bracket
[tex]39b - 462 + 209b = 282[/tex]
Collect like terms
[tex]39b + 209b = 282+462[/tex]
[tex]248b = 744[/tex]
Solve for b
[tex]b = \frac{744}{248}[/tex]
[tex]b = 3[/tex]
Solve for c
[tex]c = \frac{42 -19b}{3}[/tex]
[tex]c = \frac{42 - 19 \times 3}{3}[/tex]
[tex]c = \frac{-15}{3}[/tex]
[tex]c = -5[/tex]
Solve for a in [tex]4a = -4 - 14b - 10c[/tex]
[tex]4a = -4 - 14 \times 3 - 10 \times -5[/tex]
[tex]4a = 4[/tex]
Divide by 4
[tex]a = 1[/tex]
Recall that matrix B is:
[tex]B =\left[\begin{array}{c}a&b&c\end{array}\right][/tex]
Hence, the value of matrix B is:
[tex]B =\left[\begin{array}{c}1&3&-5\end{array}\right][/tex]
