Find the y intercept of -2,5 and 3,25

AlexFokin [52]

Answer:

Y-intercept = 13

Step-by-step explanation:

Since, given points are:

(-2,5) and (3,25)

Now, by slope intercept form:

y= mx + b

Here, m= slope and b= y-intercept

In order to find y-intercept, we must find slope firstly:

Since,

Slope= m= y2-y1 / x2-x1

m= 25 - 5 / 3 - (-2)

m= 20 / 5

m= 4

Put ‘m’ in slope intercept form:

y= 4x + b

Substitute either point into above equation:

25= 4(3) +b

25= 12 + b

25 - 12 = b

or b= 25 - 12

b= 13

Hence, y-intercept is 13.

Evaluate the expression for the given value of the variable. d=75 2d+−45d−−−−−√3=

Ahat [919]

Answer:

The expression for the given value of the variable d=75 is, 135

Step-by-step explanation:

Given the expression:

$2d+\sqrt[3]{-45d}$ ....[1]

We have to find the value for the given expression when d = 75

Substitute the value of d in [1] we have

$2(75)+\sqrt[3]{-45(75)}$

⇒ $150+\sqrt[3]{-3375}$

⇒ $150-15$

Simplify:

⇒ $135$

Therefore, the expression for the given value of the variable d=75 is, 135
