Answer:

C

Step-by-step explanation:

a typical line equation is the slope-intercept form

y = ax + b

"a" is the slope (always the factor of x) expressed as ratio of "y coordinate difference" / "x coordinate difference".

b is the y-intercept (the y value when x = 0).

going from (-2, 5) to (0, 3) we see

x changes by +2 (from -2 to 0).

y changes by -2 (from 5 to 3).

so the slope is -2/+2 = -1

using one of the points (0, 3) to solve for the missing b :

3 = -1×0 + b

b = 3

so, the equation is

y = -x + 3

miss Akunina [59]

Answer:

y> \frac{2}{3}x+3

Step-by-step explanation:

we have the points

(-3,1) and (0,3)

step 1

Find the slope m of the line

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{3-1}{0+3}

m=\frac{2}{3}

step 2

Find the equation of the line in slope intercept form

y=mx+b

we have

m=\frac{2}{3}

b=3 ----> the y-intercept is the point (0,3)

substitute the values

y=\frac{2}{3}x+3

step 3

Find the equation of the inequality

we know that

The slope is positive

Everything to the left of the line is shaded ( The inequality is of the form y > ax+b or y ≥ ax+b)

Is a dashed line (The inequality is of the form y > ax+ b or y < ax+b)

therefore

The equation of the inequality is of the form y > ax+b

The inequality is

y> \frac{2}{3}x+3

see the attached figure to better understand the problem

by using the integration formula

we get,

\\I=5\left ( \frac{t^{4}}{4} +logt -t^{2}\right )\\\\I=\frac{5}{4}t^{4}+5\log t-5t^{2}+c

now put the value of t=\sin\theta in the above equation

we get,

\int 5\cot^5\theta \sin^4\theta d\theta=\frac{5}{4}sin^{4}\theta+5\log \sin\theta - 5sin^{2} \theta+c

hence proved

A store buys an item for $94. The store then prices the item to sell to customers. What is the selling price (in dollars) the st
AnnyKZ [126]

Answer:

$152.28

Step-by-step explanation:

In order to determine the markup, multiply the original price by 62%

94 x 62% = 94 x .62 = 58.28

In order to determine the sale price, add the markup to the original price.

94 + 58.28 = $152.28
