Lawrence's parents pay him a base allowance of $10 per week and $3.20 per hour for extra chores
he completes. Mr. Williams pays Lawrence $7.80 per hour to fix broken washing machines at the
laundromat. Which equation models Lawrence's total weekly income?

Answer:

x=-4.1

Step-by-step explanation:

Multiply 5 by −2.

−10(x+3)=11

Divide each term by −10 and simplify.

x+3=−11/10

Move all terms not containing x to the right side of the equation.

x=−41/10

The result can be shown in multiple forms.

Exact Form:

x=−41/10

Decimal Form:

x=−4.1

Mixed Number Form:

x=−4 1/10

Answer:Overall, the steps for algebraically finding the range of a function are:

Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).

Find the domain of g(y), and this will be the range of f(x).

If you can't seem to solve for x, then try graphing the function to find the range.

Answer:

(-1/2,15/2)

Step-by-step explanation:

let(-4,7)=(x1,y1)

(3,8)=(x2,y2)

Then,

Using midpoint formula,

Midpoint(x,y)=((x1+x2)/2,(y1+y2)/2)

=((-4+3)/2,(7+8)/2)

=(-1/2,15/2)

Thus,midpoint(x,y)=(-1/2,15/2)

Answer:

The point (-2,0) is on the line: False

The point (0,-2) is on the line: True

The graph represents the equation 2x-2y=4: True

The graph represents the equation 2x+2y=4: False

Step-by-step explanation:

(-2,0) is not on the line, but (0,-2) is.

In order to find the answer to the last two, you must put the equation in y=mx+b form. The third question in y=mx+b form is y=x-2.

2x-2y=4

-2y=-2x+4

y=x-2, That is the equation.

The fourth question in y=mx+b form is y=-x+2.

2x+2y=4

2y=-2x+4

y=-x+2, That is not the equation.

Answer:

Each side is 14.14 feet long

Answer:

t does not matter if the two numbers are the same for multiplication or division. 4. ( ÷ ) To divide two fractions, take the second fraction, and flip it so that the top number is now on the bottom and vice versa, then multiply the two fractions together like you would for number 3.

Step-by-step explanation:

Answer: 3

Explanation:

3^2 + 12 - 6 = 5^2 - 13 + (?)

start with 3^2 or 3x3 giving us 9 then we add 12 to it 9+12=21 subtract 6. 21-6=15 then we have to make the next part equal 15 so we start off by seeing how much we have so 5^2 or 5x5=25 then subtract 25-13=12 so that means we have to see what we need to add to this to make it 15 which is 3 so that means your answer is 3

3^2 + 12 - 6 = 5^2 - 13 + 3

Answer:

f = 6

Step-by-step explanation:

Step 1: Write equation

9f + 16 = 70

Step 2: Subtract 16 on both sides

9f = 54

Step 3: Divide both sides by 9

f = 6

Answer:

X = 5

Step-by-step explanation:

For the equilibrium position of the scale,

Weights on both the sides of the scale should be equal.

Weights on left side of the scale = Weights on the right side

Weights denoting X + Weights denoting (-1) = Weights denoting (X) + Weights denoting (1)

5(X) + 6(-1) = 3(X) + 4(1)

5X - 6 = 3X + 4

5X - 3x = 6 + 4

2X = 10

X = 5

Therefore, For X = 5, scale will be in the balanced position.

Answer:

3x+10

Step-by-step explanation:

Plug n(x) into the x of the m(x) and the answer is m(n(x)).

m(x) = 3x - 2

n(x) = x + 4

Plug in n(x) to m(x) as shown here

m(n(x)) = 3(x + 4) - 2

distribute the 3

m(n(x)) = 3x + 12 - 2

simplify

m(n(x))= 3x + 10

Answer:

x =5

Step-by-step explanation:

Using the formula for calculating the distance between two points

D = √(x2-x1)²+(y2-y1)²

Given the points A(2, x) , B(x, 8) and AB = 3√2

On substituting the given values into the formula;

AB = √(x-2)²+(8-x)²

3√2= √(x-2)²+(8-x)²

square both sides

(3√2)²= (x-2)²+(8-x)²

18 = (x-2)²+(8-x)²

expand

18 = x²-4x+4+64-16x+x²

18 = 2x²-20x+68

2x²-20x+68-18 = 0

2x²-20x+50 = 0

x²-10x+25 = 0

Factorize

x²-5x-5x+16 = 0

x(x-5)-5(x-5) = 0

(x-5)(x-5) = 0

x-5 = 0 an x-5 = 0

x = 5

Answer:

M=-8

Step-by-step explanation:

21+6m=3(m−1)

Step 1: Simplify both sides of the equation.

21+6m=3(m−1)

21+6m=(3)(m)+(3)(−1)(Distribute)

21+6m=3m+−3

6m+21=3m−3

Step 2: Subtract 3m from both sides.

6m+21−3m=3m−3−3m

3m+21=−3

Step 3: Subtract 21 from both sides.

3m+21−21=−3−21

3m=−24

Step 4: Divide both sides by 3.

3m/3=-24/3

M=-8

Answer:

m = - 8

Step-by-step explanation:

Given

21 + 6m = 3(m - 1) ← distribute

21 + 6m = 3m - 3 ( subtract 3m from both sides )

21 + 3m = - 3 ( subtract 21 from both sides )

3m = - 24 ( divide both sides by 3 )

m = - 8

Answer:

  real numbers, including the boundary lines

Step-by-step explanation:

The inequality symbols in this system both include the "or equal to" case, so the boundary lines of the "shaded area" are part of the solution set.

Ordinarily, weight is a continuous variable, so we presume the weights of almonds and cashews may be any real number. The problem statement gives no clarity in that regard, so it is entirely possible that the given nuts will only be delivered in packages with integer weights.

Based on our presumption, the solution set is best described as below.

_____

Additional comments

Each inequality gives rise to a "shaded region," as shown in the second attachment. The solution set will be the doubly-shaded region, limited to the first quadrant. (Quantities of nuts cannot be negative.) Strictly speaking, the answer choices are all incorrect.

Answer:B 55

Step-by-step explanation:

Answer: 13 hours

Step-by-step explanation:

Money earned per hour = $11.00

Amount he plans to earn = $143. 00

Number of hours he will have to work to reach his goal = 143.00/11.00 = 13.

Therefore, Bryon will have to work of 13 hours to earn $ 143.00

Answer:

13 hours!

Step-by-step explanation:

All I did was divide $143.00 by $11.00 and got 13!

Or you could multiply $11.00 by 13 to get $143.00

Answer:

x = -3

Step-by-step explanation:

Step 1: Add 1.4 to both sides.

0.7x − 1.4 + 1.4 = −3.5 + 1.4

0.7x = −2.1

Step 2: Divide both sides by 0.7.

0.7x/0.7 = −2.1/0.7

x= −3

Hope this helps

Answer:

x= -3

Step-by-step explanation:

add 1.4 on both sides giving you

0.7x/0.7 = -2.1/0.7 and 0.7x cancels out leaving you with -2.1 divided by 0.7

when you divide you Get  -3
