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

write in slope intercept form an equation of the line that passes through the given points (-2,3) (2,7)

yarga [219]

1. Slope = Yb - Ya / Xb - Xa
= 7-3/2-(-2)
= 7-3/2+2
= 4/4
= 1

2. Y-intercept
Y = mx + b
7 = (1)(2) + b
7 = 2 + b
7 - 2 = 2-2 + b (two’s cancel out and we are just left with our b on the right side)
5 = B

Therefore, the equation is: Y = 1x + 5 which is also the same thing as: Y= X +5.

What is the measure of z?

Lady bird [3.3K]

Answer:

The missing angle is 24 degrees

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

x+156 = 180

Subtract 156 from each side

x+156-156 = 180- 156

x = 24

The missing angle is 24 degrees
