What is the area of the trapezoid shown?​

Answer:

-2

Step-by-step explanation:

5(2z + 4) = 0

Divide both sides by 5.

2z + 4 = 0

Subtract 4 from both sides.

2z = -4

Divide both sides by 2.

z = -2

Answer:

Z=-2

Step-by-step explanation:

5(2z+4)=0

2z+4=0/5=0

2z=0-4=-4

z=-4/2=-2

z=-2

Answer:

d. -5/2x + 5 (negative five-halves x + 5)

Step-by-step explanation:

In order to find the equation for the line that passes through these points, you must identify the slope and y-intercept. You can find the slope by finding the change in y divided by the change in x:

using (0, 5) and (2, 0),

change in y = 5

change in x = -2

(change in y)/(change in x) = -5/2

So, the slope is -5/2. You don't need to calculate the y-intercept since one of the points already is the y-intercept; when x is 0, y is 5, so the y-intercept is 5. Now, you can write your equation:

using y = mx + b, where m = slope and b = y-intercept,

y = -5/2x + 5

Step-by-step explanation:

Answer:

357

96 - 14 = 82

Step-by-step explanation:

Required :

use three of these digits (8 5 3 7) to write down the smallest possible 3-digit number.

To obtain the smallest possible 3 - digit number :

Start with the smallest digit folloqed by the next and so on ; Therefore we have ;

3, then 5, then 7 = 357

The largest possible answer to the subtraction using the digits : 6194

To obtain this :

Right hand side must be as large as possible and the left hand side as small as possible ;

Largest possible 2 - digit number = 96

Smallest possible 2 - digit number = 14

96 - 14 = 82

D. the 1/4 and 4 and get the same thing so it is more than one

2/5 is the answer because you have to divided by 2 both

Answer: 2/5

Step-by-step explanation:

When you simplify fractions you need to find a number that can divide into both numbers. In this case it would be two, so 4/2= 2 and 10/2= 5. Put you answers together and you will get 2/5.

Hope this helped! :D

Answer:

y = - [tex]\frac{3}{2}[/tex] x

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (2, - 3) ← 2 points on the line

m = [tex]\frac{-3=0}{2-0}[/tex] = - [tex]\frac{3}{2}[/tex]

Since the line crosses the y- axis at (0, 0 ) ⇒ b = 0

y = - [tex]\frac{3}{2}[/tex] x ← equation of line

Answer:

It simply means getting rid of the square root or radical in the denominator

Step-by-step explanation:

Rationalizing the denominator simply means getting rid of the square root or radical symbol in the denominator thereby making the denominator to be just a whole number.

For example if we want to rationalize the denominator in; 3/√2

We will multiply the numerator and the denominator by √2 to get rid of the radical in the denominator which is the square root sign.

Thus;

(3/√2) × (√2)/(√2)

This gives;

(3√2)2

Answer:

"To rationalize the denominator means to eliminate any radical expressions in the denominator such as square roots and cube roots." It is done usually by multiplying both numerator and denominator by the radical expression or another expression including the radical to be eliminated.

After 7 years: $81,500

If x=salary and t=years with company, then x=6400+2500t

Step-by-step explanation:

Answer:

11. #1 90 degrees

    #2 45 degrees

    #3 45 degrees

    #4 90 degrees

12. 6x-21 = 45

    add 21 to both sides

    6x= 66

    Divide by 6

    66/6=11 so x=11
