The answer is 12. Matthew would be 12 & Elizabeth would be 7. 12+7=19. So C is your answer.
Answer:
Parabola
Step-by-step explanation:
We are given that a function

The given function is an equation of parabola along y- axis.
General equation of parabola along y- axis with vertex (h,k) is given by


Compare it with given equation then we get
h=5, k=3
Vertex of given parabola =(5,3)
Substitute x=0 then we get

y-intercept of parabola is at (0,28).
Answer:
50°
Step-by-step explanation:
Opposite angels of a parallelogram are congruent to each other.
This means:
<ADC = <ABC
<ADC = 38° + 12°
<ADC = 50°
Since <ADC = <ABC, therefore,
<ABC = 50°
Answer:
1/3
Step-by-step explanation:
-1/3 divided by 3/5 = -5/9
-2/9 - -5/9 = 1/3
Given:
The algebra tiles of an equation.
To find:
The equation represented by the given model.
Solution:
On the left side of the model we have 4 tiles of (-x) and 3 tiles of (-1). So,



On the right side of the model we have 8 tiles of (-1). So,


Now, equate the LHS and RHS to get the equation.

Therefore, the equation for the given model is
.
