Answer:
y=2x+8
Step-by-step explanation:
Alright so, to find the equation, we need to find the slope first. We can do that by turning the input and output into coordinates.
(1,10) and (2,12)
To find the slope, we do:
Which equals to 2
So right now we can say that the equation is:
y=2x+b
In order to find b, the constant, we just need to plug in the y values and x value of a coordinate:
10=2(1)+b
10=2+b
8=b
So now we can say that the equation is:
y=2x+8
In this pattern , the numbers are doubling..
2,4,6,8,10...
Answer: 4:5
Explanation:
Steve earns 8 dollars an hour. His brother earns 10 dollars an hour.
The ratio is Steve:Brother, which is 8:10.
This can be treated the same was as a fraction and simplified, dividing both sides by 2, which becomes 4:5
Answer:
2,023
Step-by-step explanation:
P(8) = 25(8)²-24(8)+615
= 1600- 192 +615
= 2,023
Answer:
To find this out, we first need to see the change, is it a positive change or a negative change? Well in this case, as the temperature is increasing, we find that the change is positive. The next step we need to do, id that, how much was the change by, we can find this out by finding the absolute value of the difference of -16°F and 7°F
The absolute value means, the operations answer has to be positive, if not then it will become positive.
|-16°F -7°F|
=> |-23°F|
=> 23°F
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
