That is where the function equals 0
0=5x-20
add 20 both sides
20=5x
divide 5
4=x
the zero is at x=4
(4,0)
Answer:
Angles C and D are what I think are called Supplementary angles. Therefore they equal 180 degrees.
Step-by-step explanation:
If you subtract the measure of angle D by 180 degrees then you should get the measure of angle C which is 56 degrees. I don't really know what they are asking for in the first question. You didn't put any of the choices. :)) Think this may be right.
Answer:
The Value of x = 43.2
Step-by-step explanation:
<em>Explanation</em>:-
The conditions of similar two triangles
- same shape , but not necessarily the same size
- corresponding angles are equal
- corresponding sides are in the same ratio
In ΔCDE ~ ΔFGE
Given diagram
ΔCDE ~ ΔFGE
corresponding sides are in the same ratio
cross multiplication , we get
25 x = 1080
<u><em>Final answer</em></u>:-
The value of x =43.2
Answer:
b) 3
Step-by-step explanation:
4.5+1.5x=18-3x
1) Subtract 4.5 from both sides:
1.5x=13.5-3x
2) Add 3x to both sides:
4.5x=13.5
3) Divide both sides by 4.5:
x=3
Answer:
y = -0.25x + 2.25
Step-by-step explanation:
First, you can simplify the equation of the line it's perpendicular to (2y = 8x - 6) by dividing both sides by 2. This means you would get y = 4x - 3. From that you can conclude that the slope of that line is 4.
Lines always have a slope that is the negative reciprocal of the slope of the line they are perpendicular to, so you know the slope of the line is going to be -1/4.
So far, you have the equation y = -1/4x + b and you have to find b.
You can substitute in the point (-3, 3) so you would have 3= -1/4 * -3 + b
Solving,
3 = 3/4 + b
b = 2 and 1/4
Therefore the equation is y = -1/4x + 2 1/4 or y = -0.25x + 2.25
