Hi there!
h(x) = 5x + 11
To find h(7) - 3, we can substitute 7 for x and subtract 3:
h(7) = 5(7) + 11 - 3
Simplify:
h(7) = 35 + 11 - 3
h(7) = 43
Hello, first you look at the number of tricycle you need to sell in order to make $50.00. This would be
tricycles. We round this up to 13 since we do not have half a tricycle.
Knowing this, you won't actually need all the other given parts since you only need to know that you need 2 pedals to make a tricycle. Multiply these pedals by 13 you'll get:
.
ANSWER: B. You would need 26 pedals in order to make $50.00
Answer:
Step-by-step explanation:
Vertex form of a quadratic is given by:
Where (h, k) is the vertex and <em>a</em> is the leading coefficient.
We are given that the vertex is (3, 1). Hence, <em>h</em> = 3 and <em>k </em>= 1. By substitution:
We are also given a point (2, -6). This means that when <em>x </em>= 2, <em>f(x)</em> = -6. Hence:
Solve for <em>a</em>. Subtract:
Simplify:
Therefore:
Hence, our quadratic is:
Answer:
The first one is 5.83 or -5 5/6
The second one is -414 1/3
The last one is 290
When the multiples of the equations in a system is added or subtracted, the resulting equation together with any of the original equation will result in the same answer.
Hence, the system of equations
x + 4y = 2
7x = 14
will also have a solution of (2, 0).
