Answer:
6
Step-by-step explanation:
To find the greatest common factor of two numbers you find the largest number that can evenly go into both numbers
For example, the greatest number that can even;y go into 12 and 18 is 6
6 x 2 = 12
6 x 3 = 18
There is no number greater than six that can evenly go into both of those numbers therefore it must be the GCF
Answer:
x=-2 and y=2
Step-by-step explanation:
Do simultaneous equations
-8x + 4y = 24 <em>(multiply everything in the equation by -7)</em>
-7x + 7y = 28 <em>(multiply everything in the equation by 8)</em>
56x - 28y = -168
-56x + 56y = 224
<em>(add equations, ie add 'x' parts, 'y' parts, and numerical parts)</em>
<em> </em>28y = 56
∴y = 2
-8x + 4y = 24
-8x + 4(2) = 24
-8x = 16
∴x=-2
Lemme know if you have questions :D
F(x)= 15 because 5 times -5 is -25 and -25+40 is 15
