which number is a zero of f(x) = 2x (x + 7) ( x-4)
Answer:
0, -7, 4
Step-by-step explanation:
Zeros of a function are values that make the function = 0
So, f(x) = 2x(x + 7)(x - 4) = 0
x = 0 or x + 7= 0 or x - 4 = 0
x = -7 x = 4
Note: If you were to graph f(x), the graph would intercept the x-axis at 0, -7, and 4

Answer:
[tex]y = \frac{1}{2} x- 4[/tex]
Step-by-step explanation:
You can solve this by saying:
[tex]\Delta y = s \Delta x[/tex]
so in this case we have
[tex]y - (-2) = \frac{1}{2}(x- 4)\\[/tex]
Now we can simply solve for y:
[tex]y + 2 = \frac{1}{2} x- 2\\y = \frac{1}{2} x- 4[/tex]

In triangle ABC, the measure of angle CAB is 80° and the measure of angle ABC is 45.5°.
What is the measure of angle BCA in degrees?
A 125.5°
B 54.5°
C 55.5°
D 64.5°
Answer: B
Because triangles add up to 180 degrees, all you need to do is subtract 45.5 and 80 from 180, which gives you 54.5 degrees.

A rectangle has a length of 4 meters. The width is 2 meters more than the length. Work out the area.
Answer:
24 m^2
Step-by-step explanation:
Given data
Length= 4 meters
Width= 2+4= 6 meters
We know that the expression for the area of a rectangle is given as
A= Lenght* Width
A= 4*6
A= 24m^2
Hence the area is 24 m^2

Step-by-step explanation:
Answer:
14
Step-by-step explanation:
The triangle side rule is that the two smaller side have to be added together and be greater than the longest side
6+8=14
so any number that is 14 or more cannot be the other side
Therefore the third side must be less than 14 inches
