Answer:
D
Step-by-step explanation:
I am just cool like that trust me
<span>Consider the line y = 2x + 1, shown at the right. Notice that this slope will be the same if the points (1,3) and (2, 5) are used for the calculations. For straight lines, the rate of change (slope) is constant (always the same). For every one unit that is moved on the x-axis, two units are moved on the y-axis.</span>
Answer:
Don't worry! This is not that hard! You got this! You can use this for checking :)
Plus we have to use x-y and use the numbers given for each question
15. x-y if x=6 and x=-3
6-(-3) negative plus negative equals positive
6+3= 9
16. x= -7 x=1
-7-1= -8
17. x=-2 y=-6
-2-(-6) negative plus negative equals positive
-2+6= 4
18. x=9 y=11
9-11= -2
19. x=-1 y=-1
-1-(-1)
-1+2= 1
20. x=-5 y=5
-5-5= -10
21. The high temp. is 6 and the low temp. is -3 It sasking for the differnece between the two.
6-(-3)
6+3=9
The difference between the high temp. and low temp. is 9 degrees Fahrenheit
22. This question is a little tricky but don't worry!
From -7 to 7. To reach -7 to 0, that is 7 degrees. To reach 7 from 0, that is also 7 degrees. So you add 7 and 7!
7+7= 14
The temperature increased 14 degrees Fahrenheit.
Hope this helps! Good luck on your quiz and I hope you pass :)
2(h) + 2(i)
2(7) + 2(3)
14 + 6 = 20
The area of triangle = 1/2 b h
where b = base and h = height
so b = 5 cm and h = 6 cm
Now you can find A = 1/2 (5)(6) = 1/2 (30) = 15
answer
A = 15 cm^2
hope that helps
