Answer:
x=-6
Step-by-step explanation:
Answer:
[tex]h^{-1}[/tex] (x) = 2x - 6
Step-by-step explanation:
let y = h(x) and rearrange making x the subject
y = [tex]\frac{1}{2}[/tex] x + 3 ( multiply through by 2 to clear the fraction )
2y = x + 6 ( subtract 6 from both sides )
2y - 6 = x
Change y back into terms of x with x = [tex]h^{-1}[/tex] (x)
[tex]h^{-1}[/tex] (x) = 2x - 6

cos B = O.05. what is the approximate measure of angle B
The value of the measure of angle B will be;
⇒ ∠ B = 87.13°
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The value is,
⇒ cos B = 0.05
Now,
Since, The value is,
⇒ cos B = 0.05
Taking cos inverse both side, we get;
⇒ cos⁻¹ cos B = cos⁻¹ 0.05
⇒ B = 87.13°
Thus, The value of angle B = 87.13°

Mehvish buys 1/2 kg carrots, 3 kg potatoes, 2 kg onions and 1 1/2kg of chicken.
PRICE LIST
carrots: 50p per kg
potatoes: 64 per kg
onions: 42p per kg
Chicken: £6 per kg
She pays with a £20 note.
Work out the change that Mehvish should get.
Answer:
The amount of change will be £7.99
Step-by-step explanation:
Here, we want to calculate the amount of change that Mehvish should get
1/2 kg carrots at 50 p per kg will be;
1/2 * 50 = 25 p
3 kg potatoes at 64 p per kg will be
3 * 64 = p 192
2 kg onions at 42 p per kg
2 * 42 p = 84 p
1 1/2 kg chicken at £6 per kg will be:
since £1 is 100 p
1.5 * 6 = £9 (9 * 100 p = 900p)
since £1 is 100 p
£20 will be;
20 * 100 = 2,000 p
So let us make the subtraction as follows;
2,000- 900 - 84-192 - 25 = 799 p
In pounds, this is divided by 100
we have this as 799/100 = £7.99

Answer:
y = -7
Step-by-step explanation:
5x+8y=29
5(17)+8y=29 (simplify by multiplying)
85+8y=29 (subtract 85 from both sides)
8y= -56 (divide both sides by 8y)
y = -7

want a brainlist and a thanks:
1-answer the question correctly
2-explain it correctly
3-make sure the explanation is understandable
Answer:
$2.58
Step-by-step explanation:
4.45*0.42 = 1.87
4.45 - 1.87 = 2.58
When you multiply things under 0, but still positive, you get the percentage,
for example 0.42 is 42 percent, 0.50 is 50%, and 0.15 is 15%. Which is why you multiply 0.42 by 4.45, you get 1.87.
4.45 minus 1.87 because,
You have 42% of 4.45, but you need to take 42% off.

A new car is purchased for 25000 dollars. The value of the car depreciates at 8.25% per year. What will the value of the car be, , after 15 years?
Given:
Price of a new car = 25000
Depreciation rate = 8.25% = 0.0825
Time = 15 years.
To find:
The value of the car after 15 years.
Solution:
The exponential decay model is
[tex]y=a(1-r)^t[/tex]
Where, a is the initial value, r is the rate of decay and t is number of years.
Putting a=25000, r=0.0825 and t=15 in the above formula.
[tex]y=25000(1-0.0825)^{15}[/tex]
[tex]y=25000(0.9175)^{15}[/tex]
[tex]y=25000(0.274847)[/tex]
[tex]y=6871.175[/tex]
Therefore, the value of the car after 15 years will be 6871.175.

Write an exponential function whose graph passes through the given points (0, - 2) and (- 1, - 4)
Answer:
[tex]y = 2(0.5) {}^{x} [/tex]
Step-by-step explanation:
Use the general formula of exponential equation
[tex]y = ab {}^{x} [/tex]
Plug 0,2 into the function
[tex] - 2 = ab {}^{0} [/tex]
[tex] - 2 = a \times 1[/tex]
[tex]a = - 2[/tex]
[tex]y = - 2b {}^{x} [/tex]
[tex] - 4 = - 2b {}^{ - 1} [/tex]
[tex]2 = b {}^{ - 1} [/tex]
[tex] {2}^{ \frac{ 1}{ - 1} } [/tex]
[tex]2 {}^{ - 1} = 0.5[/tex]
B=0.5
[tex]y = 2(0.5) {}^{x} [/tex]
What is the measure of arc CD?
A. 124
B. 62
C. 64
D. 60
Help plz!
Answer:
Option D
Step-by-step explanation:
By inscribed angle theorem,
" Measure of an inscribed angle by the arc measures half of the measure of the arc"
m(arc BCD) = 2m(∠BED)
And m(arc BCD) = m(arc BC) + m(arc CD)
m(arc BC) + m(arc CD) = 2m(∠BED)
64° + m(arc CD) = 2(62°)
m(arc CD) = 124 - 64
= 60°
Option D is the answer.

Marcus took her client out for dinner that costs $157.75 before taxes. If she paid $7.89 on the meal , calculate the tax rate
Answer:
5%
Step-by-step explanation:
A tax is a compulsory sum levied by the government or an agency of the government on goods and services. Taxes raises the price of products
Tax rate is the percentage a person pays as tax
tax rate = [tex]\frac{tax paid}{cost of the dinner}[/tex] × 100
[tex]\frac{7.89}{157.75}[/tex] × 100 = 5%
She paid a tax rate of 5% on the dinner
