Answer:
C, Linear
General Formulas and Concepts:
<u>Algebra I
</u>
- Linear - Proportional relationship y = mx + b
- Nonlinear - Any graph that has a degree x higher than 1
Step-by-step explanation:
<u>Step 1: Define</u>
y = 7x + 14
<u>Step 2: Identify</u>
We see a linear equation (proportional relationship). Therefore, we have a linear equation.
Since the parabola is connecting the points, it means that the points given are on the parabola or that the points are solutions of the parabola. Thus, when we substitute the points into the function, we should end up with the correct y-value.
To find the correct choice, let's test a point. An easy point to test I believe would be (-3, 0) because we should be getting 0 as a y-value. Let's test:
We can see that Choice B is the correct function, because it produces 0 when we substitute . Thus, Choice B, or (x + 3)(x - 4) is the answer.
Answer:
The answer to your question is
Step-by-step explanation:
Process
1.- Get to points of the line
A (-2, 0)
B (0, -1)
2.- Find the slope of the line
Slope = m =
Substitution
m =
3.- Find the equation of the line
y - y1 = m(x - x1)
Substitution
y - 0 = -1/2(x + 2)
Simplification
y = -1/2x - 1
Answer:
36
Step-by-step explanation:
make proportion giants to elves
120/144 = 90/x cross multiply
120x =144*90
120x =12960 divide by 120
x = 108
so if there are 90 giants in the theater there are 108 elves also
considering that total 144 elves can be in the theater subtract 144 and 108 so 36 more elves can be admitted
