Answer:
The solution of the system is (5, 20).
Step-by-step explanation:
y = 4x and 3x + 2y = 55 are simultaneous equations. To find the unknowns, we have to solve these equations simultaneously.
The first can be rewritten as
4x – y = 0.
Therefore, we have:
4x – y = 0
3x + 2y = 55
Multiplying the first equation by 2 all through, we have
8x – 2y = 0.
So we can now combine the second equation with the first multiplied by 2.
8x – 2y = 0
3x + 2y = 55
Adding these equations we have:
11x = 55
Divide both sides by 11 and we have
x = 5
Substitute x = 5 in equation 1, we have
4(5) – y = 0
y = 20.
Therefore, x = 5 and y = 20.
The solution of the system is (5, 20).

T
S
X
23
30°
R
Answer:
angleWTR + angleWTU = 180°
Thus they are supplementary.
Option B.
What is the measure of Angle HEG?
Answer:
angle HEG = 12 degrees
Step-by-step explanation:
A line is 180 degrees. Since there is a right angle there, you know that angleHEG and 78 added together is 90degrees
x + 78 = 90 >> subtract 78 from both sides
x = 12
angle HEG = 12 degrees
Answer:
18 degrees
Step-by-step explanation:
There is a little box on the left that indicates both angles together make a 90 degree angle so you just have to do 90 - 78 to get the answer.

what’s the equation?
Answer:
The equation is;
y = 2x^2 -8x + 12
Step-by-step explanation:
The vertex form can be written as;
a(x-h)^2 + k
(h,k) represents the coordinates of the vertex
In this case, we have this as (2,4)
The value of a is positive as the parabola opens up and it is the axis of symmetry
It is the x value that divides the graph into 2
Thus, we have x as = 2
so the equation of the graph will be;
2(x-2)^2 + 4
2(x^2 - 4x + 4) + 4
= 2x^2 -8x + 8 + 4
= 2x^2 -8x + 12
How many 6-ounce bottles can mr.Phillip fill with 64 ounces of blue 12 ounces of yellow and 32 ounces of white
Answer: 18 bottles
Step-by-step explanation:
To solve the above question, we have to add the total number of ounces. Thai will be:
= 64 + 12 + 32
= 108 ounces
We then divide 108 ounces by 6 ounces . This will then be:
= 108 ounce / 6 ounces
=18 bottles

Answer:
f(6) = 82
Step-by-step explanation:
f(x) = 2x^2 + 5√(x-2)
f(6) = 2(6)^2 + 5√(6 - 2)
f(6) = 2(36) + 5√4
f(6) = 72 + 5(2)
f(6) = 72 + 10
f(6) = 82
