Answer:
x = 10
Step-by-step explanation:
Lett angle 1 and angle 5 lie on the same straight line. This shows that they are supplementary
Hence;
<1 + <5 = 180
11x - 9 + 7x + 9 = 180
18x = 180
x = 180/18
x = 10
Hence the value of x is 10

Find the input (x) of the function y = 1/4x+ 12 if the output
(y) is 6
Answer:
x = -24
Step-by-step explanation:
y = 1/4x+12 (Substitute 6 for y)
6 = 1/4x+12 (Subtract 12 from both sides)
6-12= -6 so its now -6 = 1/4x and since its a fraction you want to multiply both sides by the reciprocal
4*-6 = 1/4x*4 (1/4*4=1 which is 1x or x)
-24 = x
Answer:
y=1/4x+12
6=1/4x+12
1/4x=6-12
1/4x=-6
0.25x=-6
x=-6÷0.25
x=-24

2.0 x 10^5
Answer:
2^6 x 10^5
Step-by-step explanation:
10^5
= ( 2 x 5 )^5
= 2^5 x 5^5
2 x 10^5
= 2^1 x 2^5 x 10^5
= 2^( 1 + 5 ) x 10^5
= 2^6 x 10^5

what is the area of triangle EDF?
Answer:
4.5
Step-by-step explanation:
∠BAC ~ ∠EDF means that the triangles are similar. So the legs of the triangle share the same proportions, even if the sizes are different.
Since they share the same proportions, the same operations can be performed on each base to find the area.
The answer can be found with the knowledge that the area of a triangle is half of the height * width. You know the width of ∠BAC is 4, and the area is 8, so 16 (the area doubled) / 4 is the height. The width and height of ∠BAC are the same, and since the proportions are also the same, the width and height of ∠EDF are both 3. So the area is the width (3) times the height (3) divided by 2.
3*3 = 9
9/2 = 4.5
So the area is 4.5
8. A cellphone company charges $29.99 per month for the first 500 minutes of calls and $0.30 a minute for any calls over the 500-minute limit. . Last month Demetria made 615 minutes of calls on her cellphone. Excluding tax, what were the total charges for her cellphone calls last month? A. $29.99 B. $34.50 C. $64.49 D. $184.50
Answer:
C) $64.49
Step-by-step explanation:
let 'x' = #minutes
cost = 29.99 + 0.3(x-500)
= 29.99 + .3(115)
= 29.99 + 34.50
= $64.49
Oliver is playing a game in which he has to choose one of three numbers (6, 7, or 8) and then one of five vowels (a, e, i, o, or u). How many possible outcomes are there?
Answer:
There are 15 possible outcomes
Step-by-step explanation:
Here, we want to get the number of possible results
From the question, we can see that each of the numbers have 5 different vowel attachment
What this mean is that, we have;
6a , 6e, 6i, 6o and 6u
For the three numbers, the possible results would be;
5 * 3 = 15
What is the inverse of the function f(x) = 2x + 1?
o hex) = x-1
h(x) =
10x) = 3x-2
h(x) = 5x + 2
Answer:
y = x /2 - 1/2
Step-by-step explanation:
y = h(x)
y = 2x + 1 Interchange x and y
x = 2y + 1 Subtract 1
x - 1 = 2y Divide by 2
x/2 - 1/2 = y
y = x/2 - 1/2

Stephen is merging onto a highway. The increase in Stephen's speed for the first 8 seconds can be described by the function f(t)=t2+13t, where t is time in seconds. Which is the average rate of change of f(t) between t=2 and t=6?
Answer:
21m/s
Step-by-step explanation:
The average rate of change is expressed as;
A(t) = f(b) - f(a)/b-a
a = 2, b = 6
f(2) = 2² + 13(2)
f(2) = 4 + 26
f(2) = 30
f(6) = 6² + 13(6)
f(6) = 36 + 78
f(6)= 114
b- a = 6-2
b-a = 4
Substitute;
A(t) = 114 - 30/4
A(t) = 84/4
A(t) = 21
Hence the average rateof change is 21m/s

How would someone Algebraically determine X-Y intercepts?
Answer:
y-int: -6
x-int: -2/5 and 3
Step-by-step explanation:
you can find the y-intercept by substituting zero in for every 'x' in the equation;
y = 5(0) - 13(0) - 6
y = -6
to find the x-intercept(s), factor the trinomial by trying to find a pair of factors that multiply to 6 and add to -13; the factors that work are:
(5x + 2)(x - 3)
now set each factor equal to zero and solve for 'x':
5x + 2 = 0
5x = -2
x = -2/5
x - 3 = 0
x = 3
Which are steps in the process of completing the square used to solve the equation 3 – 4x = 5x2 – 14x? Check all that apply.
3 = 5(x2 + 2x)
3 = 5x2 – 10x
4 = 5(x2 – 2x + 1)
8 = 5(x2 – 2x + 1)
3 = 5(x – 1)2
4 = 5(x – 1)2
StartFraction 8 Over 5 EndFraction = (x – 1)2
Answer:
1. 3 = 5x2 – 10x
2. 8 = 5(x2 – 2x + 1)
3. StartFraction 8 Over 5 EndFraction = (x – 1)2
Step-by-step explanation:
3-4x=5x^2-14x
3=5x^2-14x+4x
3=5x^2-10x
5x^2-10x-3=0
1. 3 = 5x2 – 10x
2. 8 = 5(x2 – 2x + 1)
8=5x^2-10x+5
8-5=5x^2-10x
3=5x^2-10x
3. StartFraction 8 Over 5 EndFraction = (x – 1)2
8/5=x^2-2x+1
Cross product
8=5(x^2-2x+1)
8=5x^2-10x+5
8-5=5x^2-10x
3=5x^2-10x
Answer:
3 - 4x = 5x2 - 14x
= 3 - 5x2 = - 14x + 4x
= 3 - 10 = 10x
= 7 = 10x
= x = 7/10
= x = 0.7
