Answer:
x = 21/2
y = -19/2
Step-by-step explanation:
5x - 17 = 4y + 7x
5x - 7x - 4y = 17
-2x - 4y = 17
6x + 8y = - 13
-2x - 4y = 17 | ×2 |
6x + 8y = - 13 | ×1 |
-4x - 8y = 34
6x + 8y = - 13
___________+
2x = 21
x = 21/2
-2x - 4y = 17
-2(21/2) - 4y = 17
-21 - 4y = 17
-4y = 17 + 21
-4y = 38
y = -38/4
y = -19/2
Hi there! The answer is £198.
If you spend 3 / 12 of a certain amount of money, you have 9 / 12 of the money left.
Simplify the fraction.
9 / 12 = 3 / 4.
To find the amount of money left, we multiply this factor by 264. We get the following
£264 × 3/4 = £264 × 0.75 = £198
Therefore the answer is £198

Answer:
Step-by-step explanation:
The zeros are the values of x for which y = 0
Quadratic formula
x = [5 ± √(5² – 4·1·6)] / [2·1]
= [5 ± √1] / 2
= [5 ± 1] /2
= 2, 3
sum of zeros = 5
