Answer:
1 solution
Step-by-step explanation:
4h + 2 = 3h - 7
Subtract 3h from both sides:
(4h + 2) - 3h = (3h - 7) - 3h
h + 2 = -7
Then, subtract 2 from both sides to isolate h:
(h + 2) - 2 = (-7) - 2
h = -9
There is one solution, -9.

a) Write down the name of the planet with the greatest mass.
b) Work out the radius of Mercury giving your answer as an ordinary number.
Answer:
Mass is the property of a body that measure its inertia. It is taken as the measure of the amount of material it contains and have weight in gravitational field
Mass is also refers as the weight of an object. It is measured in grams (g) and kilograms (kg)
Radius of an object is defined as a straight line from the centre of a circular object to the circumference of the circular object
According to the data given of five planets
(a) The planet which has greatest mass is Mars that is 6.42 x 1023 kg
Radius of a given object can be calculated by dividing the diameter of the given object by 2.
(b) Radius of the mercury = Diameter given in kilometers / 2
= 4.88 × 10³ / 2
= 2.44 x 103 km

Find the equation of the line which passes through (6,2) and is parallel to the line with equation 3y=5x+2
Answer:
3y = 5x - 24
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
3y = 5x + 2 ( divide through by 3 )
y = [tex]\frac{5}{3}[/tex] x + [tex]\frac{2}{3}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{5}{3}[/tex]
• Parallel lines have equal slopes , then
y = [tex]\frac{5}{3}[/tex] x + c ← is the partial equation of the parallel line
to find c substitute (6, 2 ) into the partial equation
2 = 10 + c ⇒ c = 2 - 10 = - 8
y = [tex]\frac{5}{3}[/tex] x - 8 ← equation in slope- intercept form
multiply through by 3 to clear the fraction
3y = 5x - 24 ← equation of parallel line

Find domain and range

The given function is [tex]\[f\left( x \right) = \sqrt {2 - x - {x^2}} \][/tex]
Domain: The domain of a function is the set of input or argument values for which the function is real.
Use commutative properties to reorder the terms
[tex]\[f(x) = \sqrt { - x + 2} - {x^2}\][/tex]
Separate the function into parts to determine the domain of each part
[tex]\[f\left( x \right) = \sqrt { - x + 2} \]=-x+2= x^{2}[/tex]
Domain is XR (all real numbers)
The function has no undefined points nor domain constraints. Therefore, the domain is X∈R.
Range: The set of values of the dependent variable for which a function is defined
Range of [tex]\[\left\{ {f \in \mathbb{R}:f \le \frac{1}{4}(1 + 4\sqrt 2 )} \right\}\][/tex]
Combine the ranges of all domain intervals to obtain the function range.

Mr. Johnson earns $5.40 an hour. One week, he worked 40 hours and 2 hours overtime, If he is paid time and one-half for overtime, how much did he earn?
When Mr. Johnson earns $5.40 an hour. One week, he worked 40 hours and 2 hours overtime, If he is paid time and one-half for overtime then the total amount he earned is $232.2
Given,
The amount he earns in an hour = $5.40
Total number of hours he worked =40 hours
The amount he earns = 5.40×40 = $216
Overtime hours = 2 hours
Overtime payment per hour= 5.40×1.5= $8.1
The amount he earns for overtime = 2×8.1= $16.2
The total amount he earned = 216+16.2= $232.2

Harry is saving for the deposit for an apartment. He has 21 350 EUR, but needs at least 30
000 EUR in 3 years time.
He compares banks that offer annual interest compounded monthly.
What is the minimum interest rate he requires to meet his needs? Give your answer to three
significant figures.
[Answer format: 00.0%]
We need to know about the concept of compound interest to solve the given problem. The minimum interest rate that Harry needs to meet his need is 11.4%
Compound interest can be described as the interest that you earn on both the principal amount and the interest earned. In this question it is said that the bank offers annual interest compounded monthly, we will be using a formula to solve this problem. Since Harry has 21350 EUR we will take that as the principal amount and the minimum amount that he needs is 30000 EUR we will consider this to be the final amount at the end of 3 years. We need to find out the rate of interest that the bank offers.
A=P[tex](1+\frac{r}{12} )^{12t}[/tex] where A is amount, P is principal, r is the rate of interest and t is time period.
P=21350 EUR
A=30000 EUR
t=3
30000=21350[tex](1+\frac{r}{12}) ^{36}[/tex]
[tex]\frac{600}{427} =(1+\frac{r}{12}) ^{36}[/tex]
1+[tex]\frac{r}{12}[/tex]=1.00949
r/12=0.00949
r=0.1139
r=11.4%
Therefore we found that the minimum rate of interest Harry requires to meet his needs is 11.4%

Find two consecutive even integers such that 6 times the smaller integer is 36 more than 3 times the larger integer. Please Help me!
The integers are 14 and 16.
How to calculate the value?Let the integers be represented by x and x+2.
It was stated that the consecutive even integers such that 6 times the smaller integer is 36 more than 3 times the larger integer.
This will be:
6(x) = 3(x + 2) + 36
6x = 3x + 6 + 36
6x = 3x + 42
6x - 3x = 32
3x = 42
Divide
3x/3 = 42/3
x = 14.
The larger number will be:
= x + 2
