Answer:
x,y = 13/3, -10/3
Step-by-step explanation:
8x+8y=8
8x+2y=28 Subtract eq1 by eq 2
6y=-20
y=-20/6 y = -10/3
8x - 80/3=8
8x=34 2/3
x=4 1/3
x=13/3
Hope this helps plz hit the crown :D
Answer:
the three one
Step-by-step explanation:
srry i dont really know, i havent done this before
For this case we have the following expression:
We can rewrite the expression by factoring
Rewriting the expression we have:
Then, using the distributive property for the negative sign we have:
Thus, we have that one of the factors of the given expression is:
12-7x
Answer:
A factor of the given expression is:
12-7x
option 3
Answer:
C. 6 inches
Step-by-step explanation:
It is a 45, 45, 90 triangle because there is a 90 degree angle and since both of the legs are equal it is an isosceles triangle so the two angles are equal, so they can both only be 45 because together they have to equal 90.
That means the two radii are x and the hypotenuse is x√2 so √72 = x√2
√72 = x√2
now you divide both sides by √2 so that the x is alone
√72/√2 = x you have to multiply the √72/√2 by √2 because the denominator can not be a radical, You dont have to do it to the x because you are multiply both the numerator and denominator by√2 so it is like 1
√72/√2 * √2/√2
√144/√4 the √144 is 12 and the √4 is 2
12/2 now simplify
6
