1) move the x to the side with the whole number
* remember the form of y = mx + b
* when you move it to the other side, the sign changes… so watch out for signs
[ 2y = -4x + 8 ]
2) divide everything by the number that’s with y since you wanna isolate for y… this case it’s 2
[ y = -2x + 4 ]

If lines joined each given point on the graph to the origin, which points would be on lines that represent a unit rate greater t

Brut [27]

Answer:

The first three, (2, 8), (3, 9) and (4, 10).

Step-by-step explanation:

The unit rate, or rate of change, is another term for the slope.

The formula for slope is

$m=\frac{y_2-y_1}{x_2-x_1}$ .

The slope in the table would be given by

m = (22-11)/(10-5) = 11/5 = 2.2.

For the slope of the line that goes through (2, 8) and (0, 0), we have

m = (8-0)/(2-0) = 8/2 = 4. This is greater than 2.2.

For the slope of the line that goes through (3, 9) and (0, 0), we have

m = (9-0)/(3-0) = 9/3 = 3. This is greater than 2.2.

For the slope of the line that goes through (4, 10) and (0, 0), we have

m = (10-0)/(4-0)/ = 10/4 = 2.5. This is greater than 2.2.

For the slope of the line that goes through (5, 8) and (0, 0), we have

m = (8-0)/(5-0) = 8/5 = 1.6. This is not greater than 2.2.

For the slope of the line that goes through (6, 7) and (0, 0), we have

m = (7-0)/(6-0) = 7/6 = 1.16. this is not greater than 2.2.

For the slope of the line that goes through (7, 6) and (0, 0), we have

m = (6-0)/(7-0) = 6/7 = 0.86. This is not greater than 2.2.

Determine whether y2=3x+1 is a function.

bazaltina [42]

Answer: it is not a function

Step-by-step explanation:

Given :

$y^{2}$ = 3x + 1

The first thing is to make y the subject of the formula, that means we will take the square root of both sides

y = $\sqrt{3x + 1}$

since y = $\sqrt{3x + 1}$ , the the value of y could be positive or negative.

For example , $\sqrt{4}$ = ± 2 , since -2 x -2 will also give + 4

For y = $\sqrt{3x + 1}$ to be a function , there must be a unique value for y for each value of x , but this is not the case as y could be positive or negative for a single value of x , so it is not a function.

Clark and Lana take a 30-year home mortgage of $128,000 at 7.8%, compounded monthly. They make their regular monthly payments fo

svp [43]

Answer:

Step-by-step explanation:

From the given information:

The present value of the house = 128000

interest rate compounded monthly r = 7.8% = 0.078

number of months in a year n= 12

duration of time t = 30 years

To find their regular monthly payment, we have:
