Answer:

y = 5x - 2

Step-by-step explanation:

Hello, V,

In the slope-intercept form of the equation of a straight line, replace the y-intercept (b) with -2 and the slope (m) with 5:

General form:  y = mx + b

This case:         y = 5x - 2  (answer)

y = mx + b

m = slope

b = y-intercept


Given: m = 5 and b = -2


Answer:

y = 5x - 2

KIM [24]

Answer:

8\:\text{ft}

Step-by-step explanation:

The length of the arc is proportional to the degree measure it in encompasses. Since there are 360 degrees in a circle and the arc is 120 degrees, the arc's length will be \frac{120}{360}=\frac{1}{3} of the circle's length (circumference).

The circumference of a circle is given by 2\pi r, where r is the radius of the circle. Therefore, the circumference of the circle is 2\pi(4)=8\pi. As we found earlier, the length of the arc is \frac{1}{3} of this circumference. Therefore, the arc's length is 8\pi\cdot \frac{1}{3}=\frac{8\pi}{3}.

To the nearest integer, this is \approx \boxed{8\:\text{ft}}.

Can y’all help me on Thai one thank you

Karmin will make $18.4 for working an hour after the increase.

Step-by-step explanation:

Step 1:

First, we need to determine how much Karmin made an hour.

Karmin's hourly rate = \frac{480}{30} = 16.

So Karmen made $16 every hour that she worked. She worked for 30 hours and earned $480.

She will get a 15% increase in her hourly rate this month.

Step 2:

We need to determine how much 15% of $16 is.

15% of $16 = \frac{15}{100} (16) = 0.15 (16)= 2.4.

So her 15% increase amounts to $2.4.

So the hourly rate for this month 16 + 2.4 = 18.4.

So Karmin will make $18.4 for working 1 hour.

The area of a rectangle has decreased by 2%.
MissTica

Answer:

The other side was decreased to approximately .89 times its original size, meaning it was reduced by approximately 11%

Step-by-step explanation:

We can start with the basic equation for the area of a rectangle:

l × w = a

And now express the changes described above as an equation, using "p" as the amount that the width is changed:

(l × 1.1) × (w × p) = a × .98

Now let's rearrange both of those equations to solve for a / l.  Starting with the first and easiest:

w = a/l

now the second one:

1.1l × wp = 0.98a

wp = 0.98a / 1.1l

1.1 wp / 0.98 = a/l

Now with both of those equalling a/l, we can equate them:

1.1 wp / 0.98 =  w

We can then divide both sides by w, eliminating it

1.1wp / 0.98w = w/w

1.1p / 0.98 = 1

And solve for p

1.1p = 0.98

p = 0.98 / 1.1

p ≈ 0.89

So the width is scaled by approximately 89%

We can double check that too.  Let's multiply that by the scaled length and see if we get the two percent decrease:

.89 × 1.1 = 0.979

That should be 0.98, and we're close enough.  That difference of 1/1000 is due to rounding the 0.98 / 1.1 to .89.  The actual result of that fraction is 0.89090909...  if we multiply that by 1.1, we get exactly .98.
