The answer should be -7°. What I did was just subtract 7 for each day. Im pretty sure there is a faster way, but this is how I did it
Answer:
The solution set is {4, -1}
Step-by-step explanation:
6x²- 18x -18 = 6
6x²- 18x -18 - 6 = 0
6x²- 18x -24 = 0
6(x² - 3x - 4) = 0
6(x - 4)(x + 1) = 0
6 = 0 not true
x - 4 = 0 ; x + 1 = 0
x = 4 x = - 1
The solution set is {4, -1}
Perimeter is legnth +legnth + width + width or
P=2L+2W
L=2W
subsitute L=2W for L in P=2L+2W
P=2(2W)+2W
P=4W+2W
P=6W
we know that Perimiter=30 so
30=6W
divide both sides by 6
5=Width
subsitute W=5 for W in L=2W
L=2(5)
L=10
to check
10=2(10)+2(5)
30=20+10
30=30
checks
Legnght=10
Width=5
Answer:
<u>Option 4:</u> -6.1 - (-3.13)
Step-by-step explanation:
Let's solve each option individually to see if -2.97 fits as the solution:
-6.1 - 3.13 = -9.23
-6.1 - (-31.3) = 25.2
-0.61 - (-3.13) = 2.52
<u>-6.1 - (-3.13) = </u><u>-2.97 </u>
As you can see, -2.97 is the answer to Option 4.
So, the decimal -2.97 is the solution to the subtraction problem in Option 4.
the equation line of the scatter plot is y = ×+10
