B. 1? T = 12

Step-by-step explanation:

Since the bedroom measures 12 feet long, the answer or the product should be 12 (12 only)

He uses “1?” to measure the bedroom, and we need to know HOW MUCH TIMES he uses it.

So, 1? T will be the equation since we need to know how much times he uses the ruler.

7x+23 would be the answer

Answer:

The answer is: (x , y) = (19/10 , 1/5)

Step-by-step explanation:

Solve the equation for y-

y = 4 - 2x

4x - 3y = 7

Substitute the given value of y into the equation-

4 x - 3 ( 4 - 2x ) = 7

Solve the equation for x-

x = 19/10

Substitute the given value of x into the equation y = 4 - 2x-

y= 4 - 2 * 19/10

Solve the equation for y-

y = 1/5

The possible solution of the system is the ordered pair ( x , y )-

( x , y ) = ( 19/10 , 1/5)

Check if the given ordered pair is the solution of the system of equations-

{2 * 19/10 + 1/5 =4

4 * 19/10 - 3*1/5 =7}

Simplify the equalities-

4 = 4

7 = 7

Since all equalities are proven true the ordered pair is the solution of the system-

( x , y) = (19/10, 1/5)

FINALLY haha the solution is: ( x , y ) = (19/10 , 1/5)

Answer:

A

Step-by-step explanation:

You must multiply the number your buying by the price then you need to multiply by 1.07 because you need 7% or .07 to get the tax but you want to add that to the old number so you need a 1 in front so the answer is c(p) = 1.07(3p) however you still need the $15 gift card so instead you add the 7% into the three dollars you are multiplying by the number then subtract the 15 dollars because you aren't really paying. The reasonable domain is 0 1 2 3 4 because the number 5 would be over the 15 dollar limit.

Answer:

c(10)=40

c(15)=52.5

Step-by-step explanation:

c(10) means you plug 10 into your x same with (c15) you plug in 15 so for c(10) it would be 2.5(10) + 15 which is 40

The value of c(10) and c(15) is 40 and 65 respectively.

The given function is c(x) = 2.5x + 15.

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Now, c(10)=2.5(10)+15=40

c(15)=2.5(15)+15=52.5

Given c(20) = 65

So, 65=2.5x+15

⇒50=2.5x

⇒x=20

Therefore, the value of c(10) and c(15) is 40 and 65 respectively.

Answer:

y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))

Step-by-step explanation:

Solve for y:

-4 y^2 - 3 x y + x^2 = 0

Hint: | Multiply both sides by a term to make the coefficient of y^2 positive.

Multiply both sides by -1:

4 y^2 + 3 x y - x^2 = 0

Hint: | Using the quadratic formula, solve for y.

y = (-3 x ± 5 sqrt(x^2))/8:

Answer: y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))

Answer:

Bed A --- Third Option

Bed B --- Fifth Option

Step-by-step explanation:

Flower Bed A)

The formula for circumference is:

[tex]C=2\pi r[/tex]

The diameter of A is 10 feet. So, its radius is 5 feet.

Substitute 5 for r. So, the circumference of Bed A is:

[tex]C=2\pi (5)=10\pi\text{ feet}[/tex]

The formula for the area of a circle is:

[tex]A=\pi r^2[/tex]

Substitute 5 for r:

[tex]A=\pi (5)^2[/tex]

Square and simplify:

[tex]A=25\pi \text{ square feet}[/tex]

So, the circumference of Bed A is 10π feet and its area is 25π square feet.

Therefore, match Bed A to the third option.

Flower Bed B)

The radius of Bed B is 6 feet. Again, we can use the circumference and area formulas. Substitute 6 for r for circumference:

[tex]C=2\pi (6)[/tex]

Multiply:

[tex]C=12\pi\text{ feet}[/tex]

Substitute 6 for r for the area formula:

[tex]A=\pi(6)^2[/tex]

Square and simplify:

[tex]A=36\pi\text{ square feet}[/tex]

So, Bed B has a 12π feet circumference and a 36π square feet area.

Therefore, match Bed B to the fifth option.

And we're done!

Answer:

f(-3)=-17

Step-by-step explanation:

Substitue -3 for t

-2(-3)^2 + 1

Simplify

-2(9) + 1

-18 + 1

Answer: -17

A function is defined as a relation between a set of inputs having one output each.

The value of the function f(t) = -2t² + 1 at t = -3 is -17.

The domain of the function is -17.

The range of the function is -3.

A function is defined as a relation between a set of inputs having one output each.

f(x) = x + 2

At x = 2,

f(2) = 2 + 2 = 4

Domain = 2

Range = 4

We have,

f(t) = -2t² + 1

We need to find for t = -3.

f (-3) = -2 ( -3 )² + 1

[ -3 x -3 = 9 ]

f (-3) = -2 x 9 + 1 = -18 + 1 = -17

Thus the value of the function f(t) = -2t² + 1 at t = -3 is -17.
