A. set the top equation as x=something. you can do this by transforming functions.
answer x=2y-8
Then you substitute 2y-8 for x in the bottom problem. 4(2y-8) - 8y= 10.
Solve for y. you will get a false equation. -32=10. Proved.

B. we know that the lines are parallel. if the line don't have a solution that means that they don't intersect. that means they must be parallel because parallel lines never intersect.

10. <br>V=720 cm<br>L=?<br>P=15 cm<br>T=8 cm<br>A. 6 cm<br>B. 8 cm<br>C.10 cm<br>D. 12 cm​
grin007 [14]

Answer:

6 cm

Step-by-step explanation:

Given the information :

V=720 cm

L=?

P=15 cm

T=8 cm

The volume = L * P * T

V = L * P * T

720 = L * 15 * 8

720 = L * 120

L = 720 / 120

L = 6 cm

3.Find the area of Triangle and Parallelogram having base 13.5cm and height is 18cm.​
patriot [66]
  • Base=13.5cm
  • Height=18cm

\\ \sf\longmapsto Area=\dfrac{1}{2}Base\times Height

\\ \sf\longmapsto Area=\dfrac{1}{2}(18)(13.5)

\\ \sf\longmapsto Area=9(13.5)

\\ \sf\longmapsto Area=121.5cm^2

The total cost of a sweater and a pair of pants was $89.47. If the price of the sweater was $8.53 less than the pair of pants, w
Strike441 [17]

Answer:

Let S = price of sweater

Let P = price of pants

S + P = 89.47 because that was the total spent

S = P - 8.53   because the sweater is 8.53 less than pants

Substitute P-8.53 in place of S in the

1st equation and solve for P

P - 8.53 + P = 89.47

2P - 8.53 = 89.47     add 8.53 to both sides

2P = 89.47 + 8.53

2P = 98.00  divide both sides by 2

P = 98.00/2

P = $49.00

S = P - 8.53

S = 49.00-8.53

S = $40.47

A sweater costs $40.47 and the pants cost $49.00

emmainna [20.7K]

Answer:

The degree of the polynomial is 3

Step-by-step explanation:

Given:

a^3+3a^2-5a

To Find:

The degree of the polynomial= ?

Solution:

The degree of the polynomial   is the value of the greatest exponent of any expression (except the constant ) in the polynomial. To find the degree all that you have to do is find the largest exponent in the polynomial

Here in the given polynomial

a^3+3a^2- 5a

The terms are

a^3

3a^2

5a

The term  a^3 has  the largest exponent of  3

Note:  The degree of the polynomial does not depend  on coefficients of the terms
