We know that
in the equation <span>ŷ = 10 + 20x
the value of 10 is the p</span><span>redicted value of Y,
given X=0 value.
</span>It is also known as Y intersect
Answer:
- He must sell each CD for R1,10 to make 40% profit
Step-by-step explanation:
R40×5%=2
R40-2=R38
40%×38=R15,2
15,2+40=55,2
55,2÷50=R1,10
i didnt do the radio sum...
Answer:
-4x-13
Step-by-step explanation:
To figure out the sum, you have to add like terms.
This is how it would look like:

What do you mean by "solve this?" Until you set f(x) = to some constant number, you don't have an equation and thus can't expect to find solutions.
Why don't we take <span>3x^2-18x+27 and set it = to 0, and only then try to solve this equation?
</span><span>3x^2-18x+27 = 0. Dividing both sides by 3, we get x^2 - 6x + 9= 0, which can be factored as
(x-3)^2 = 0. Taking the sqrt of both sides, we get x-3 = 0. Actually, there are 2 roots: 3 and 3. Again, this statement is true only if we set </span><span>3x^2-18x+27 = to 0.</span>
Answer:
18
Step-by-step explanation:
324 = s^2 -->
sqrt324 = s -->
sqrt(2^2 * 9^2) = s -->
2*9 = s -->
18 = s
