Rate of change = (y2 - y1) / (x2 - x1)
r = (1 - 1) / (0 - 2)
r = 0 / -2
r = 0

Solve these simultaneous equations Using the algerbraic method

kherson [118]

The second equation equals: 3X +18y=60 (Both sides times 3)
And then use this new equation minus the first equation, you will get:
Left side: (3X +18y) - (<span>3x+6y)
Right side: 60-30
So 12y=30
Then y=2.5
Take y value into one of the three equations, you will get x=5

or

in another easier way:

Directly minus the second equation from the first one:
</span>(3x+6y) -(<span>X+6y)=10
</span>2X = 10
X = 5
Get Y is easy, Y=2.5

3(5y - 4) + 31 - 3y) = 3(2y - 3)<br> How to solve it

kumpel [21]

After solving $3(5y - 4) + 31 - 3y = 3(2y - 3)$ the value of y is $y=-\frac{14}{3}\,\,or\,\,y= -4.66$

Step-by-step explanation:

We need to solve the expression:

$3(5y - 4) + 31 - 3y = 3(2y - 3)$

and find the value of y

Solving:

$3(5y - 4) + 31 - 3y = 3(2y - 3)\\15y-12+31-3y=6y-9\\Combining\,\,like\,\,terms:\\15y-3y-6y=-9+12-31\\15y-9y=12-40\\6y=-28\\y=-\frac{28}{6}\\y=-\frac{14}{3}\\or\,\,y= -4.66$

So, after solving $3(5y - 4) + 31 - 3y = 3(2y - 3)$ the value of y is $y=-\frac{14}{3}\,\,or\,\,y= -4.66$

The resale value of a certain car decreases over time. Use the line of best fit to estimate what the car will be worth in 7 year

Pie

Answer:

C. $5500

Step-by-step explanation:

Find the point on the horizontal scale where Time is 7. Follow that line up to the red "line of best fit". Then follow that horizontally to see where it falls on the Resale Value scale. It is between 5 and 6 (thousands of dollars) on that scale.

The only answer choice that is between $5000 and $6000 is ...

C. $5500
