The answer is 5/2

Step-by-step explanation:

5/6 times 3

15/6=

5/2

The fraction form of (5/6)×3 after simplification is  5/2.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, (5/6)×3.

= (5/6)×(3/1).

Now in fraction multiplication, we simply multiply the numerator with the numerator and the denominator with the denominator.

= (5×3)/(6×1).

= 15/6.

= 5/2.

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]

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

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

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.

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.
