How do you do -2z<-6

1 answer:

4 0

Isolate the z

divide -2 from both sides

Note: because you are dividing a negative, you will have to flip the sign

-2z < -6

-2z/-2 < -6/-2

z > 3 is your answer

hope this helps

During a sale, a store offered a 30% discount on a camera that originally sold for $810. After the sale, the discounted price of

Lady_Fox [76]

Start with with original price and find 30% of that price:

30% of 810: (0.30)(810) = 243

Now take that 30% away:

810 - 243 = 567

That's the sale price: $567

Find 30% of the sale price:

30% of 567: (0.30)(567) = 170.10

Now add that 30% on to the sale price:

567 + 1701.0 = 737.10

The final price described is $737.10.

Now we need to relate that final price to the original price:

737.10 ÷ 810 = 0.91

This means that the final price is 91% of the original price.

What is the equation of the line shown in this graph? graph shown down below

Andrew [12]

Answer: $x = -2$

Step-by-step explanation:

In the given picture , the line is parallel to the y- axis and passing through (-2,2) and (-2 , -3).

The equation of line parallel to y-axis (has slope undefined) is given by

x= a , where a is the point on x-axis through which the line is passing .

For the given graph , the line is passing through x = -2.

Therefore , the equation of the given line = $x = -2$

Hence, the correct answer = $x = -2$

What is the rate of change and initial value for the linear relation that includes the points shown in the table?

Wittaler [7]

Answer:

Initial value $12$ , rate of change: $-2$

Step-by-step explanation:

Step 1

Find the rate of change

we know that

In a linear equation the rate of change is equal to the slope

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

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

we have

$A(1,10)\ B(2,8)$

Substitute the values

$m=\frac{8-10}{2-1}$

$m=-2$ ----> rate of change

Step 2

Find the initial value

The equation of the line into slope-point form is equal to

$y-y1=m(x-x1)$

Substitute

$y-10=-2(x-1)$

$y=-2x+2+10$ $y=-2x+12$

The initial value is the value of y when the value of x is equal to zero (is the y-intercept)

$y=-2*0+12=12$ ----> initial value
