Its pretty simple
9x-7y = 22
x + 3y = -24
(9x-7y = 22)
-9(x + 3y = -24)
= -9x -27y = 216
+ 9x-7y = 22
= -34y = 238
= / -34 = 238/-34
y = -7
now plug -7 in one of the equation
x + 3(-7) = -24
x -21 = -24
+21. +21
x = -3
so answer is x = -3 and y = -7
Answer:
t = 7 + 3i
Step-by-step explanation:
(t-7)^2 + 18 = 9
(t-7)^2 = 9 - 18
(t-7)^2 = -9
(t-7) = sqrt(-9) = |3| sqrt(-1)
t = 7 + 3i
Answer:
Step-by-step explanation:
So to graph an inverse of the function given we have to switch the x and y values of the function:
So Ill do some points and the rest of the points the same process is applicable.
So our first point is (-1,1)
So our inverse point would be (1,-1)
The second point is (-2,2)
So our inverse point would be (2,-2)
The third point is (-3,3)
So our inverse point would be (3,-3)
Hope this helps!
Answer: Jenna sold 280 and Becca sold 105 boxes.
Step-by-step explanation:
Let 3x be the number of cookies Becca sold.
Then, the number of cookies Jenna sold = 8x
Since Combined, they sold a total of 385 boxes of cookies.
So, 
So, Jenna sold 8(35) = 280 boxes
and Becca sold 3(35)= 105 boxes
Hence, Jenna sold 280 and Becca sold 105 boxes.
The answer would be 4.385
