Answer:

9c

Add and subtract

Answer:

One solution:(1,2)

Step-by-step explanation:

   y = x + 1

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

  -2x - (x +1) = -4

  -3x = -3

Solve equation [2] for the variable  x  

 3x = 3  

    x = 1  

By now we know this much :

   x = 1

   y = x+1

Use the  x  value to solve for  y  

   y = (1)+1 = 2

Hope this helps :D please mark brainliest if correct

Answer:

Answer:

x = 70

y = 110

z = 30

Step-by-step explanation:

all triangles add up to 180

30 + 80 = 110

180 - 110 = 70

x = 70

30 + 40 = 70

70 + 80 = 150

180 - 150 = 30

z = 30

40 + 30 = 70

180 - 70 = 110

y = 110

What is your last question?

Answer:

The dimensions of the room is 8 feet × 12 feet.

Step-by-step explanation:

The area of the house, A = 96 ft²

The link is 12 feet less than three times the width of the room .

Let the width of the room is x.

Length = 3x-12 ...(1)

The area of a rectangular room is given by :

A = lb

96 = (3x-12)x

[tex]3x^2-12x-96=0\\\\x^2-4x-32=0\\\\x^2-8x+4x-32=0\\\\x(x-8)+4(x-8)\\\\(x+4)(x-8)=0\\\\x=-4,8[/tex]

Neglecting negative value, width = 8 feet

Put x = 8 in equation (1)

Length = 3(8) - 12

= 12 feet

Hence, the dimensions of the room is 8 feet × 12 feet.

Step-by-step explanation:

Answer: She should have multiplied One-half (4) (3.5) by 5 squared.

Step-by-step explanation:

The calculation of Beth is wrong. Since Beth enlarged the triangle below by a scale of 5, she should find the area of the traingle and then multiply by 5².

This will be:

= 1/2 × 4 × 3.5 × 5²

= 2 × 3.5 × 25

= 175cm²

Answer:

If both the members and nonmembers take 5 aerobics classes, they will have paid the same amount of money.

Step-by-step explanation:

To solve this problem, we can create a chart:

Step One: Where x equals the number of aerobics classes,

                           Members                   Nonmembers    

Cost in Dollars        10+3x                         0+5x            

Step Two: We create an equation to solve for x.

Member Cost=Nonmember Cost

10+3x= 0+5x

Step Three: Solve for x:

10+3x= 5x Subtract 3 from both sides

10=5x-3x Combine like terms

10=2x

5=x

∴For five aerobics classes, the cost of members and nonmembers will be the same.

Answer:

g(-3) = -7

Step-by-step explanation:

[tex]g(x) = -3x^2 - 5x + 5\\\\g(-3)=-3(-3)^{2} -5(-3)+5\\\\g(-3)= -27+15+5\\\\g(-3)=-7[/tex]

Answer:

G(-3) = -7

Answer:

Circumference of wheel=πd

Circumference of wheel =22*2.1/7

Circumference of wheel =6.6 Mrs

It coveres 6.6mtrs in one round

Then in 100 rounds it will take 6.6*100=660mtrs

Answer

x=6, y=21/2

Explanation

The 86 degrees is just to make you confused.

Since this is a congruent triangle, you can just follow these steps.

Line AB: To get from 4 to 6, you multiply by 1.5.

Line BC: Divide 9 by 1.5 to get x. 9 divided by 1.5 is 6.

Line AC: Multiply 7 by 1.5 to get y. 7 times 1.5 is 10.5.

So the correct answer is the first choice; x=6, y=21/2 (this is also 10.5).

Answer: since JG is the long line and JL is half of that line, 32/2=16

so JL=16

x = 62 /9     y = 11 /9   z = − 5 /27

Step-by-step explanation:

Answer:

33

Explanation:

replace y with 18 and solve.

18 = 2/3x - 4

add 4 to both sides and divide by 2/3

Answer:

y=-4x+41

Step-by-step explanation:

y=mx+b

5=-4(9)+b ---> b=41

y=-4x+41

Answer: He still owns 64% of the Mr.Williams' original parking.

Step-by-step explanation:

Let x = Area of the original parking plot.

First he sold 20% of his lot to neighbor .

Sold plot = 20% of x = 0.20x  [Replace 'of' by '×' and divide number by 100 to remove %]

Reminder= x-0.20x= (1-0.20)x=0.80x

Again he sold 20% of the remainder .

Sold plot = 20% of (0.80x) = 0.20 (0.80x)

= 0.16x

Remainder plot = 0.80x-0.16x= 0.64x

Percent of Mr.Williams' original parking lot does he still own = [tex]\dfrac{0.64x}{x}\times100=64\%[/tex]

Hence, he still owns 64% of the Mr.Williams' original parking.

Answer:

4 or |4| (Absolute value of 4)

Answer:

6

Step-by-step explanation:

The graph of the absolute value function is an inverted "V" such that the vertex is at (-4, -5) and opens downwards.

How to calculate the modular function?

Among modular functions, f(x) = |x| has its domain given by the real numbers and its range given by the positive real numbers. This is because the modular function will make |-y| = -(-y) = y given every negative y-value.

Given modular function is :

y = -|x + 4| - 5.

Hence, to plot the graph of a modular function, we need to determine some values for x and then apply them to the function f(x) = | x |.
