Find the slope of 10y = 7x + 5.<br> Round to the third.

hram777 [196]

Answer:

0.7

Step-by-step explanation:

10y = 7x + 5

Divide both sides by 10.

y = 7x/10 + 5/10

y = 0.7x + 0.5

On a straight line of the form y = kx + m, k is the slope of the line.

In our line, y = 0.7x + 0.5, k is 0.7. Thus, the slope of our function is 0.7

What is the answer Timothy curtain company is making curtains for a local hotel he wants each certain to be 48 inches long at th

Travka [436]

Answer:

180 feet

Step-by-step explanation:

The length of each curtain = 48 inches. Let the length of the curtain in feet be represented by x.

But,

1 inch = 12 feet

So that,

48 inches = x feet

⇒ x = $\frac{48}{12}$

= 4

Thus,

48 inches = 4 feet

The number of feet of fabric needed for 45 curtains can be determined as:

45 x 4 feet = 180 feet

Therefore, 180 feet of fabric would be needed to make 45 curtains.

10xy(4xy^3-7xy+9y^2)

Thepotemich [5.8K]

Answer:

$40x^{2} y^{4} -70x^{2} y^{2} +90xy^{3}$

Step-by-step explanation:

$10xy(4xy^{3} -7xy+9y^2)$

1. 10xy · 4xy^3 = $40x^2y^4$

2. 10xy · -7xy = $-70x^{2} y^{2}$

3. 10xy · 9y^2 = $90xy^3$

Final step: add up all of those values together to make an equation!

Answer: $40x^2y^4+$ $-70x^2y^2+$ $90xy^3$

Final Answer: $40x^2y^4-70x^2y^2+90xy^3$
