4x - y = 6
4x - 6 = y
2x - 5y = 12
2x - 5(4x - 6) = 12
2x - 20x + 30 = 12
2x - 20x = 12 - 30
-18x = -18
x = -18/-18
x = 1
4x - 6 = y
4(1) - 6 = y
4 - 6 = y
-2 = y
so the 2 lines given intersect at (1,-2)
y = p - 3x......(1,-2)...x = 1 and y = -2
-2 = p - 3(1)
-2 = p - 3
-2 + 3 = p
1 = p <===
To answer this question we will have to keep the following two points in mind:
#1. The <u>sum</u> of a number with another number means to <u>add </u>the given two numbers.
#2.<u> Twice</u> means to <u>multiply by 2.</u> In other words it means to double.
Therefore, "twice the sum" would mean to multiply the sum by 2.
Now, in our question we will have, "the sum of y and 9 would be: and twice this sum would be:
Thus, "twice the sum of y and 9" is:
Answer:
6 dishes
Step-by-step explanation:
since he made 2 dishes and there is a two in the numerator, all we have to do is multiply by 6 to get 2 by itself
Answer:
15i√2
Step-by-step explanation:
5√(-18)
= 5√(-2 x 9)
= 5 x 3 x √-2
= 15√-2
= 15i√2
