since it is absolute values, it is:

4z+6=1/222 +4

and 4z-6=1/22+4

You solve from there. Hopefully that is right and hopefully it helped

Select all of the following that are ordered pairs of the given function.

podryga [215]

Answer:

(-1, 5)

(0, 3)

(2, -1)

Step-by-step explanation:

we have

$f(x)=3-2x$

Remember that

If a ordered pair is a solution of the given function, then the ordered pair must satisfy the given function

<u><em>Verify each case</em></u>

case a) (-2, -1)

substitute the value of x and the value of y in the given function and compare the result

$-1=3-2(-2)$

$-1=7$ ---> is not true

therefore

Is not a ordered pair of the given function

case b) (-1, 5)

substitute the value of x and the value of y in the given function and compare the result

$5=3-2(-1)$

$5=5$ ---> is true

therefore

Is a ordered pair of the given function

case c) (0, 3)

substitute the value of x and the value of y in the given function and compare the result

$3=3-2(0)$

$3=3$ ---> is true

therefore

Is a ordered pair of the given function

case d) (1,0)

substitute the value of x and the value of y in the given function and compare the result

$0=3-2(1)$

$0=1$ ---> is not true

therefore

Is not a ordered pair of the given function

case e) (2, -1)

substitute the value of x and the value of y in the given function and compare the result

$-1=3-2(2)$

$-1=-1$ ---> is true

therefore

Is a ordered pair of the given function

Write an equation in slope-intercept form of the line that passes through the given points.(3,5) and (0,4) please answer with al

alukav5142 [94]

Answer:

Y = (1/3)X + 4

Step-by-step explanation:

You need to know the equation Y = mX + b, for two sets of coordinates

Therefore we need to find the slope and the interception of the given points.

1) The slope of the line

We can use the point slope form, and clear for the slope m

y - y1 = m (x-x1)

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

The data given is: A (3, 5) and B (0, 4)

Then substitute in the slope: m = (5 -4)) / (3 -0) = (1/3)

m = 1/3

2) Find the interception

From the general equation slope intercept Y = mX + b, clear b

b = Y - mX

Now substitute any given point to obtain b the interception

b = Y - mX

Lets choose point A (3, 5), remember m = 1/3

b =5 - (1/3)(3)= 4

b = 4

3) Therefore with the values of m and b, the general equation for the slope intercept form is:

Y = mX + b -->

Y = (1/3)X + 4

Can you explain what went wrong and the actual answers these 3

vlada-n [284]

For the first one, they got rid of the 6x when they shouldn’t have, and the correct answer is x = 21.5

For the second one, 47 would be subtracted by 180, not 90, and the correct answer is 133

For the third one, 5x - 10 doesn’t equal 115, 5x - 10 equals 180 - 115, and the correct answer is x = 17
