Answer:
y = -x +4
Step-by-step explanation:
The y-intercept of the line is at +4, so the only viable choice is the last choice.
___
Each of the equations is shown in slope-intercept form:
y = mx + b
where b is the y-intercept, the y-value when x=0. The graph shows that as point (0, 4). So, the equation you're looking for is ...
y = (some x-term) +4
If you want to spend more brain power on the problem, you can compute the slope of the line as ...
m = ∆y/∆x = (1-4)/(3-0) = -3/3 = -1
Now, you know for sure the equation of the line is ...
y = -x +4
If you factor the c out and simplify, you'll get your answer.
1c - 0.20c = c(1-0.20)
= c(0.80)
= 0.80c
Therefore, your answer is A.
Answer: +3
Step-by-step explanation:
5 + (-2) ( + × - = - ) ∴ 5 - 2 = 3
Answer: option a
Step-by-step explanation:
You must apply the formula for calculate the surface area of the prism, which is shown below:
![SA=bh+2ls+lb](https://tex.z-dn.net/?f=SA%3Dbh%2B2ls%2Blb)
Where:
b=8 cm
h=3 cm
l=10 cm
s=5 cm
When you susbstitute the values shown above into the formula for calculate the surface area, therefore you obtain:
![SA=(8cm*3cm)+2(10cm*5cm)+(10cm*8cm)\\SA=204cm^{2}](https://tex.z-dn.net/?f=SA%3D%288cm%2A3cm%29%2B2%2810cm%2A5cm%29%2B%2810cm%2A8cm%29%5C%5CSA%3D204cm%5E%7B2%7D)
