Answer:

45y-18y+54y & 10(8-y)

Step-by-step explanation:

For the first problem, you need to distribute the 9 to the 5y, -2y, and the 6y

If you do this and multiply the 9 by each of the terms you get:

45y-18y+54y

Now we can work on the second problem

When factoring, we have to find a common factor.

In this expression, the common factor is 10 because both 80 and 10 are divisible by 10!

So we but the 10 on the outside of the parentheses and divide 80 and 10 by 10 which gets us an answer of:

10(8-y)

If you were to distribute this, you would get 80-10y so we know it is correct

Hope this helps, have a great day, and please award brainliest!

Write an equation of the line passing through (-5,5) and having slope -6. Guve the answer in slope-intercept form.
Fynjy0 [20]
Passes through (-5, 5) & has a slope of -6.

We want the answer in slope-intercept form.

** Remember! Slope-intercept form : y=mx+b where m=slope, b=y-intercept.

Simply plug everything in :)

y = mx + b

y = (-6)x + (5)

Simplify.

y = -6x + 5

~Hope I helped!~

Solve this quadratic equation. Show all work. <br><br><br> 4x^2-2x-5=0
kicyunya [14]
X= -b⁺₋ √b²-4ac/2a
x= (-(-2)⁺₋√(-2)²- 4(4)(-5))/2(4)
x= 4 ⁺₋√4+80/8
x= (4⁺₋ 9.165)/8
x= 4+9.165)/8 or x= 4-9.165)/8
x= 1.40 or x= -0.896

Can someone give me the answer no links I’ll give brainliest
LiRa [457]

Answer:

1,334.5 \:  {cm}^{3}

Step-by-step explanation:

Height of the cylinder h = 17 cm

Radius of the cylinder r = 5 cm

V_{cylinder}  = \pi {r}^{2} h \\  \\  = 3.14 \times  {(5)}^{2}  \times 17 \\  \\  = 3.14 \times 25 \times 17 \\  \\V_{cylinder}  = 1,334.5 \:  {cm}^{3}

A factory packs 25 small shirts,30 medium shirtsand 15 large shirts in a box. If 550 boxes are packed with these shirts,how many
stealth61 [152]

Answer: the total number of shirts in all the boxes is 38500

Step-by-step explanation:

A factory packs 25 small shirts,30 medium shirt sand 15 large shirts in a box. This means that the total number of shirts that is packed into a box would be the sum of the small shirt, medium shirt and large shirt. It becomes

25 + 30 + 15 = 70

If 550 boxes are packed with these shirts, it means that the total number of shirts in all the boxes would be

550 × 70 = 38500

the variables x and y have a proportional relatinship and y=2/5 when x=5/8 which equation represents this relationship
mafiozo [28]

The equation is y = 16/25 x

lets find the proportional relationship,

y = kx

2/5 = k * 5/8

k = (2/5) /  (5/8)

k = 16/25

so if k, constant is 16/25

equation is:

y = 16/25 x

<h3>What are proportional relationships?</h3>

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

<h3>How do you find the proportional relationship in an equation?</h3>

The equation that represents a proportional relationship, or a line, is y = k x , where is the constant of proportionality. Use k = y x from either a table or a graph to find k and create the equation.
