The answer to this question is
x = -15 + y
Answer:
26
Step-by-step explanation:
Because DAC is a straight line we can equate that:
4x - 8 + 34 + 76 - x = 180
3x + 102 = 180
3x = 78
x = 26
This is a system of equations. We solve it by setting it up so that when we add the two equations together, one of the variables will cancel out. We can do this by multiplying the bottom equation by 3. This will make our system of equations equal:
3a + b + 225
-3a + 3b = 75
Now we add these two equations together, because the a terms will cancel out.
4b = 300.
We can find what b is by dividing both sides by 4.
b = 75
Next, we plug in b in one of the equations and solve for a. You can use either equation, but I will use the second.
75 - a = 25
Subtract 25 from both sides and add a to both sides:
a = 50
So, the first option is correct. A = 50 and b = 75.
Hi I think this answer would be b. A is backwards. C and d do not make sense
Answer:
This is a false statement:
Step-by-step explanation:
According to Remainder Theorem dividing the polynomial by some linear factor x + a, where a is just some number. As a result of the long polynomial division, you end up with some polynomial answer q(x) (the "q" standing for "the quotient polynomial") and some polynomial remainder r(x).
P(x)= (x+/-a) q(x)+r(x)
P(x)=(x+a) q(x)+r(x). Note that for x=-a
P(-a)=(-a+a) q(-a)+r(-a)= 0* q(-a)+ r(-a)
P(-a)=r(-a)
It means that P(-a) is the remainder not P(a)
Thus the given statement is false....
