Answer:

y=9x+2

Step-by-step explanation:

The standard form for a linear equation is y=mx+b. m=9 since it is slope and b=2 which is the y intercept. So the equation would be y=9x+2.

Answer:

5 x^2 + 7 x − 2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Dryer = x

Washer: x+95

Now to find x, we must create an equation.

x+(x+95)=995

Now, we can add the variables.

x+x=2x

So now it would be:

2x+95=995

Now we must solve, since there is only one variable, we need to solve the constants.

Since 95 is positive, we need to cancel it out. And since you did it to one constant, you need to do it to the other.

2x=900

(since you subtract 95 from the other constant, too.)

Now, you must divide both sides by 2.

x = 450.

Now the washer isn't what we're supposed to find, but technically, you would still need it in the problem to find the answer for the dryer.

Hope this helps!

Answer:

The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Using the slope-intercept form, the slope is 3 .

Answer:

The answer is 20

Step-by-step explanation:

When you take the height of the triangle (which is 4) you take that and divide it by 2 or multiply by 1/2 which gets you 2. Then you take the two bases of the trapizoid and add them up to get 10 and then you multiply the two from earlier by 10 to get 20.

Answer:

y = x ^2 − 99 x + 81

Step-by-step explanation:

Work backwards to find the factors from the roots, then multiply the factors together.

Answer:

8√2

2√2

Step-by-step explanation:

Using arc length for parametric equations:

s = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt

x = 2 sin²t

dx/dt = 4 sin t cos t

y = 2 cos²t

dy/dt = -4 sin t cos t

s = ∫ √((4 sin t cos t)² + (-4 sin t cos t)²) dt

s = ∫ √(32 sin²t cos²t) dt

s = ∫ 4√2 sin t cos t dt

s = ∫ 2√2 sin(2t) dt

s = -√2 cos(2t)

If we evaluate this between t=0 and t=2π, we get s = 0.  This means the particle travels forward and backward on the same curve.

sin²t and cos²t have periods of π, so if we evaluate from t=0 to t=π/2:

s = -√2 cos(2 (π/2)) − -√2 cos(0)

s = √2 + √2

s = 2√2

So the particle travels 2√2 four times from t=0 to t=2π.

The distance traveled is 8√2.  The length of the curve is 2√2.

We can check our answer by eliminating the parameter.

x + y = 2 sin²t + 2 cos²t

x + y = 2

y = 2 − x

The curve is the line y = 2 − x from (0, 2) to (2, 0).  Using distance formula to find the length of the line:

d = √((x₂ − x₁)² + (y₂ − y₁)²)

d = √((2 − 0)² + (0 − 2)²)

d = 2√2

x=12 is the correct answer

y = 3(12)-8

y = 36 - 8

y = 28

Answer:

when X= 12

then y = 3x-8

y= 3*12-8= 28

Answer:

This is a linear function.

Step-by-step explanation:

A linear function is a straight line. Once you graph the equation, you get a staright line, therefore, it's linear.

Answer:

72

Step-by-step explanation:

-4 times 2 is -8.  -8 times -9 is 72 because the two negatives cancel each other out.
