Identify the value of y.
9y+6 = 3y+3+7+26

Answers

Answer:

y=5

Step-by-step explanation:

9y+6 = 3y+3+7+26

arrange the equation so all values with y are on one side, and all regular numbers are on the other side. Make sure you change the sign when changing sides.

9y - 3y = 3 + 7 + 26 -6

6y / 6 = 30 / 6

Now divide both sides by 6 in order for y to be alone.

y = 5

Answer:

CD =7.5 AC =20

Step-by-step explanation: you can answer this question by creating a proportion. For the side AB, we can find the total length by adding AE and EB, for a total of 8. Now we can build a proportion, where x equals AC. 12.5/x= 5/8. When you build a proportion, it’s important to make sure you use the same corresponding parts in the same places, for example, in both the fractions we made for the proportion, the total side length was on the bottom. From this proportion, we now cross multiply to get 5x=100. Divide both sides by 5 and you get that the length of AC is 20. We can do the same with CD. The proportion you’d use to find CD would involve the smaller line segment over the total length of the line. This would look like so: x/20=3/8. Cross multiply again and you’d get 60=8x. Divide both sides by 8 and you’d get x=7.5. This means the length of CD is 7.5.

Convert the following equation into standard form.

[tex]y = - \frac{4x}{9} + 3[/tex]

Move the expression to the left-hand side and change its sign

Multiply both sides of the equation by 9

[tex]9y + 4x = 27[/tex]

Use the commutative property to reorder the terms

Lucy bought a table on sale for $665. This price was 24% less than the original price.
What was the original price?

Answers

Answer: Below

Step-by-step explanation:

24% is basically 0.24. Since we want to find the original price we make the equation:

x * (1 - 0.24) = 665

For x is the original price. Simplify:

x * (0.76) = 665

x = 665/0.76

x = 875

Our answer is 875

A farmer has 540 m of fencing to enclose a
rectangular area and divide it into two sections as
shown.
a) Write an equation to express the total area
enclosed as a function of the width.
b) Determine the domain and range of this area
function.
c) Determine the dimensions that give the
maximum area.

Answers

The dimensions that give the maximum area is 135 m by 135 m for a rectangular area with 540 m of fencing

What is an area?

An area is the amount of space occupied by a two dimensional shape or object.

Let w represent the width and l represent the length, hence:

540 = 2(l + w)

l = w - 270

The area (A) is:

A = length * width

A = w(w - 270) = w² - 270w

The domain of the function is (270, ∞), the range is (0, ∞).

The maximum area is at dA/dw = 0, hence:

2w - 270 = 0

w = 135 m, l = 270 - w = 135 m

The dimensions that give the maximum area is 135 m by 135 m

find the value of b if a+b+c/4=2 where a = 1 and c=2

Answers

Answer:

b = 5

Step-by-step explanation:

Solving

Step 1: Plug in the values of a and c.

[tex]\frac{1+b+2}{4} =2[/tex]

Step 2: Combine like terms on both sides.

[tex]\frac{(2+1)+b}{4}=2[/tex] [tex]\frac{3+b}{4}=2[/tex]

Step 3: Multiply both sides by 4.

[tex]\frac{3+b}{4} *4 = 2*4[/tex] [tex]3+b=8[/tex]

Step 4: Subtract 3 from both sides.

[tex]3+b-3=8-3[/tex] [tex]b=5[/tex]

Step 5: Check if solution is correct.

[tex]\frac{1+5+2}{4} = 2[/tex] [tex]\frac{8}{4} =2[/tex] [tex]2=2[/tex]

What is an equation of the line that passes through the points (5,2) and (-5,-6) PLEASE ANSWER

Answers

Answer:

y = 4/5 x - 2

Step-by-step explanation:

Find for slope first:

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

= [(-6) - 2] / [(-5) - 2]

= -8/-10

= 4/5

Solve for b. Use (5, 2)

y = mx + b

2 = 4/5 (5) + b

2 = 20/5 + b

2 = 4 + b

2 - 4 = b

-2 = b

Substitute the value of m and b.

y = mx + b

y = 4/5 x + (-2)

y = 4/5 x - 2
