Answer:
h(x) = (1/4)x - 2 which is choice A
Step-by-step explanation:
Replace f(x) with y. Then swap x and y. Lastly, solve for y to get the inverse.
f(x) = 4x+8
y = 4x+8
x = 4y+8
x-8 = 4y
4y = x-8
y = (x-8)/4
y = x/4 - 8/4
y = (1/4)x - 2
h(x) = (1/4)x - 2

A theatre ticket costs £37 plus a booking fee of 4%.
What is the total price of the ticket?
Answer:
£38.48
Step-by-step explanation:
First, we have to find what 4% of 37 is, so our equation is:
37 x 0.04 = 1.48
Then we have to add that 4% to the original cost:
1.48 + 37 = 38.48
So the total price of the theatre ticket is £38.48
What is the area of the obtuse triangle given below?

O A. 9 sq. units
B. 18 sq. units
O C. 8 sq. units
O D. 11 sq. units
SUB
Answer: 9
Step-by-step explanation:
The area of the obtuse triangle given is,
⇒ Area of triangle = 9 square units
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The obtuse triangle given below.
Here, Base = 9
And, Height = 2
Now, WE know that;
⇒ Area of triangle = 1/2 × Height × Base
Put all the values we get;
⇒ Area of triangle = 1/2 × Height × Base
⇒ Area of triangle = 1/2 × 2 × 9
⇒ Area of triangle = 9 square units
Thus, The area of the obtuse triangle given is,
⇒ Area of triangle = 9 square units

Please help, enter the coordinates of the verticales of T(-1,2) R(x-axis)(QRST) read the picture then answer. Thank you so much for your time.
Answer:
Q'(0, -1)
R'(2, 5)
S'(-1, 0)
T'(-2, 9)
Step-by-step explanation:
Rule defined by [tex]T_{(-1,2)}.R_{\text{x-axis}}[/tex]
Step 1). Reflection of the figure about x-axis
(x, y) → (x, -y)
Step 2). Followed by the translation of 1 unit to the left and 2 units up
(x, y) → (x - 1, y + 2)
Transformation of QRST by this rule,
Step 1.
Q(1, 3) → Q"(1, -3)
R(3, -3) → R"(3, 3)
S(0, 2) → S"(0, -2)
T(-2, 1) → T"(-2, -1)
Step 2.
Q"(1, -3) → Q'(0, -1)
R"(3, 3) → R'(2, 5)
S"(0, -2) → S'(-1, 0)
T"(-1, -1) → T'(-2, 9)

Reformatting the input :
Changes made to your input should not affect the solution:
(1): "1.25" was replaced by "(125/100)".
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*x*(x-3)-((125/100)*x^2)=0

Rewriting the whole as an Equivalent Fraction
4.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 4 as the denominator :
2x • (x - 3) 2x • (x - 3) • 4
2x • (x - 3) = ———————————— = ————————————————

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
4.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero :
6.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
3x•(x-8)
———————— • 4 = 0 • 4
4
Now, on the left hand side, the 4 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
3x • (x-8) = 0
Theory - Roots of a product :
6.2 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
6.3 Solve : 3x = 0
Divide both sides of the equation by 3:
x = 0
Solving a Single Variable Equation:
6.4 Solve : x-8 = 0
Add 8 to both sides of the equation :
x = 8

Help help im so confused as per usual
Answer:
Step-by-step explanation:
a. HM = 14
HN = 21
HK = 10.5
Based on intersecting chords theorem,
HK*HJ = HM*HN
10.5*HJ = 14*21 (Substitution)
HJ = 294/10.5
HJ = 28
b. VC = 7.2
VG = 12
Based on tangent-secant theorem, thus:
VD*VC = VG²
VD*7.2 = 12²
VD = 144/7.2
VD = 20
Therefore,
CD = VD - VC
CD = 20 - 7.2
CD = 12.8

Find the missing data identify given the following information. 13,17,15,20,14,x. The mean is 15
Answer:
X = 11
Step-by-step explanation:
(13 + 17 + 15 + 20 + 14 + x) ÷ 6 = 15
13 + 17 + 15 + 20 + 14 + x = 15 x 6
13 + 17 + 15 + 20 + 14 + x = 90
13 + 17 + 15 + 20 + 14 = 79
79 + x = 90
90 - 79 = 11
X = 11
