Which ordered pairs are solutions to the equation?

1 answer:

5 0

The answer is D.

y = 3x - 4

(5, 11)

11 = 3(5) - 4

11 = 15 - 4

11 = 11

(2, 2)

y = 3x - 4

2 = 3(2) - 4

2 = 6 - 4

2 = 2

Find the product of 2r^2(6r^3+14r^2-30r+14)

mylen [45]

Answer:

12 $r^{5}$ + 28 $r^{4}$ - 60 r³ + 28 r²

Step-by-step explanation:

a(b ± c) = ab ± ac (distributive property)

$a^{m} * a^{n} = a^{m+n}$

2r²(6r³ + 14r² - 30r + 14) = 12  $r^{5}$  + 28  $r^{4}$  - 60 r³ + 28 r²

Answer:

Evaluating the piecewise function when X =3, we get f(3) = 7

Step-by-step explanation:

Given the following piecewise function

f(x)= { 2x+1; where x > 0

-3 when x ≤ 0

Evaluate the function when X = 3

We will evaluate f(x) =2x+1 where x > 0, because x = 3 and 3 <0

We can't use -3, because x ≤ 0, and 3 is not less than 0.

Now, evaluating the function:

$f(x)=2x+1\\Put\:x=3\\f(3)=2(3)+1\\f(3)=6+1\\f(3)=7$

So, Evaluating the piecewise function when X =3, we get f(3) = 7

Last one for finding lengths side, please answer correctly, thank you

Answer:

(a) Width of the garden : 64 m

(b) Length of the window: 95 cm

Step-by-step explanation:

Given:

(a) The perimeter of a rectangular garden is 306 m. If the length of the garden is 89 m, what is its width?

(b) The area of a rectangular window is 5130 cm². If the width of the window is 54 cm, what is its length?

Solve:

(a) The perimeter of a rectangular garden is 306 m. If the length of the garden is 89 m, what is its width?

Formula for perimeter: P = (L + W) × 2

Which;

P = Perimeter

L = Length

W = Width

Which also could be written as:

L + L + W + W = P

Hence, since it given that;

306 = P and L = 89

Then

We know that ;

89L + 89L + W + W = 306

So we can add 89 + 89 or 89 × 2

which is 178

Now we know that;

178 + 2w = 306

Solving for 2w:

178 + 2w = 306

178-178 + 2w = 306 - 178

2w = 128

W = 64

Hence, width is 64.

Check Answer:

64 × 2 + 89 × 2 = 306

-------------------------------------------------------------------------------------------------------------

(b) The area of a rectangular window is 5130 cm². If the width of the window is 54 cm, what is its length?

Formula for area: A = Lw

Which;

A = Area

L = Length

W = Width

So, since we know the width we can just do 5130/54 to find Length

5130/54 = 95

Hence, the length of the window is 95 cm.

Check Answer :

A = Lw

A = 95 × 54

A = 5130 cm²
