Step-by-step explanation:

just reciprocate and change the negative sign to positive

Answer:

The first answer = t ≥-7

Step-by-step explanation:

If one side of an inequality is multiplied by a negative number, to find an equivalent inequality the “direction” of the inequality has to change (for example, ≥ has to change to ≤ ). Find a so that y > x is equivalent to − 3 y < a x.

Answer: B

Step-by-step explanation:-2^2 is the only negative number, 2^-2 is the only fraction, anything to 0th power equals 1, and (-2)^2 equals 4.

Answer:

The answer is B

Step-by-step explanation:

Let's solve:

(-2)^2= 4

2^0= 1

2^-2= 1/4

-2^2= - 4

Least to greatest is

-4, 1/4, 1, 4

Look back at the original equations and place them to get her with the answers to equal B

Step-by-step explanation: answer {x,y,z} = {1,-2,5}

/ Solve equation [3] for the variable x

[3] x = 2y - 5z + 30

// Plug this in for variable x in equation [1]

[1] 2•(2y-5z+30) - 5y + 3z = 27

[1] - y - 7z = -33

// Plug this in for variable x in equation [2]

[2] 4•(2y-5z+30) + 3y - 7z = -37

[2] 11y - 27z = -157

// Solve equation [1] for the variable y

[1] y = -7z + 33

// Plug this in for variable y in equation [2]

[2] 11•(-7z+33) - 27z = -157

[2] - 104z = -520

// Solve equation [2] for the variable z

[2] 104z = 520

[2] z = 5

// By now we know this much :

x = 2y-5z+30

y = -7z+33

z = 5

// Use the z value to solve for y

y = -7(5)+33 = -2

// Use the y and z values to solve for x

x = 2(-2)-5(5)+30 = 1

Answer:

6/5

Step-by-step explanation:

m=(y2-y1) /(x2-x1)

m=(5-(-1)) / (3-(-2))

m=(5+1) /(3+2)

m=6/5

Answer:

m = 6

Step-by-step explanation:

[tex]m=\frac{rise}{run}=\frac{4+2}{1-0}=\frac{6}{1}=\boxed{6}[/tex]

Hope this helps!

Answer:

The slope is 6.

Step-by-step explanation:

Using rise over run or

[tex] \frac{rise}{run} [/tex]

you would enter 4-2/1-0 which would give you 6/1. So the answer would be 6 or m = 6.

The triangle has 3 sides and angles. The measure of "d" from the given diagram is 6.48

The given diagram is a triangle. According to the SOH CAH TOA identity;

tan theta= opp/adj

Given the following

opp = d
adj = 7.2

Substitute

tan 42 = d/7.2

d = 7.2tan42
d = 6.48

Hence the measure of "d" from the given diagram is 6.48

Answer:

6) 4n+w+4h-b-16

Terms: 4n, w, 4h, -b, -16

Variable: n, w, h, b

Constant: -16

Coefficients: 4, 1, 4, -1

Step-by-step explanation:

Terms:

just substitute the '+' and '-' with comma.

For example: b+4x+54+6y+22 becomes b, 4x, 54, 6y, 22

Variables:

just list the letters (only)

For example: 8y-7+2y becomes x, y

Constants:

it is the number by themselves, no letter

For example: 5-4x-8y becomes just 5

Coefficients:

the number in front of letter (dont forget the sign, also if no number such as 'b', the coefficient is 1 because we dont typically write 1, it is assumed it goes there)

For example: 6m-2n+7 becomes 6 and -2
