Answer:
slope = 4
The line is increasing
Step-by-step explanation:
slope can be found through the equation
. So, if we plug these points in, we get
, which simplifies to 4. So, the slope is 4.
Since the slope is positive, the line is increasing.
Part A:
The most likely value of the relationship between time and distance traveled by the car is 0.99 since both of the values increase in each progression with almost constant increments.
Part B:
Slope formula has to be used.
m= (y2 - y1)/(x2 - x1)
m= (12- 4)/(30 - 10)
m=8/20
m=0.4
The slope is 0.4 and it represents speed.
Answer:
D) (9 , 5)
Step-by-step explanation:
y = x - 4
Substitute x = 9 value in the equation
y = 9 - 4 = 5
We got the y value as 5
So, (9,5) is the pair generated by the equation
2.45 pints of blue paint she use to paint her bedroom walls .
<u>Step-by-step explanation:</u>
Here we have , Kate uses 9.8 pints of white paint and blue paint to paint her bedroom walls. 3/4 of this amount is white paint, and the rest is blue paint. We need to find How many pints of blue paint did she use to paint her bedroom walls .Let's find out:
It's given that , Kate uses 9.8 pints of white paint and blue paint and 3/4 of this amount is white pain i.e.
⇒ 
⇒ 
⇒ 
So , Amount of blue paint is given by :
⇒ 
⇒ 
⇒ 
Therefore , 2.45 pints of blue paint she use to paint her bedroom walls .
Answer:
f(2) = -2
Step-by-step explanation:
To solve this, you have to plug in 2 for x
f(2) = -2^2 + 2(2) - 10
= 4 + 4 - 10
= 8 - 10
= -2
