Answer:
Step-by-step explanation:
You have 2 points given. Take them seriously. They represent actual numbers that don't need to be rounded.
The two points are (2,-2) and (-3,-6)
Now construct a line in point intercept form from these two points.
y2 = -2y1 = -6x2 = 2x1 = -3m = (y2 - y1)/(x2 - x1)
m = (-2 - - 6)/(2 - - 3)
m = 4/5
So far what you know is
y = 0.8 x + b
Use either one of the two points to get b (the y intercept)
x = 2
y = - 2
-2 = 0.8*2 + b
-2 = 1.6 + b Subtract 1.6 from both sides
-3.6 = b
y = 0.8x - 3.6

For the red one it’s 15
Long answer: so the way to do this is to find the ratio. So you look at the filled shape for the yellow ones case it’s the smaller one and the sides have a ratio of 9:6 or 3:2, now since on the other similar shape the 9 lines up with 21 we can divide that by 3 getting us 7 and multiply that by 2 and get 14.
For the red one it’s the same process, 8:6=4:3 so we and we divide 20 by 4 and get 5, then multiply that be 3 and get 15.

Answer: y = -5/3x + 4 and 5x + 2y = 4
Step-by-step explanation:
1. Firstly, we should substract 5x on both sides of the equation.
3y = -5x + 12
Then we divide by 3 on both sides of the equation. This would give us our answer.
y = -5/3x + 4
2. The answer is 5x + 2y = 4.
The slope of parallel lines should be the same. If we want to isolate y of the above the equation we should first substract 5x on both sides.
2y = -5x + 4
Then we should divide 2 on both sides of the equation.
y = -5/2x + 4
The equation above and y = -5/2x -7 have the same slope. Therefore, they are parallel.

Sheila has investments totaling $8000 in two
accounts. The savings account pays 6% interest and the
other account is in bonds paying an interest rate of
11%. If the annual interest from the two investments
totaled $780, how much did she invest in each account?
Answers
The amount she invested in each account is:
$6,000 invested at 11%
$6,000 invested at 6%
Let x represent the amount invested at 11%
Hence:
.11x+.06(8000-x)=780
.05x+480=780
Collect like terms
.05x=300
Divide both side by .05x
x=300/.05
x=$6,000
Inconclusion the amount she invested in each account is: $6,000 invested at 11% and $6,000 invested at 6%.

Compare the graph of Car A to the table of Car B to determine which car is traveling at the greates
speed and by how much. Show work.
Answers
Answer:
Car a is moving at 15 miles per hour
Its slope is 15/1
Its equation is y = 15x
Car b is moving at 7.5 miles per hour
Its slope is 7.5
Its equation is y = 7.5x
Car a is moving twice as fast as car b
Step-by-step explanation:
But here's how you solve
Chose 2 points and find the change in y and change in x, then divide in the same order.
Point 1: (1, 15)
Point 2: (2, 30)
Change in y = 15
Change in x = 1
y = miles
x = hours
15 miles/1 hour
You can also do this
Pick a point and just divide it's y by its x. For example:
(4, 60)
60 miles/4 hours
15 miles per hour
Now that we have the slope, we can get the equation for the graph:
y = 15x + 0
or just y = 15x, because there is no y-intercept
Now let's solve for car b:
Chose a point:
(3, 22.5)
Divide its y by its x
22.5/3
7.5
Car b is moving at 7.5 miles per hour
Now that we have the slope, we can get the equation for the graph:
y = 7.5x + 0
or just y = 7.5x, because there is no y-intercept
Compare the speeds
Car a: 15 mph
Car b 7.5 mph
15 > 7.5
So, Car a > Car b
15/7.5 = 2
So Car a moves twice as fast as Car b
