f(a) = a + 3. Find f(7)
Answer: a=1/2=0.5
Step-by-step explanation:
7(a)=a+3
Subtract a from both sides.
7a−a=3
Combine 7a and −a to get 6a.
6a=3
Divide both sides by 6.
a= 63

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%

The solution for the system of equation is 4534 and the graphical representation is attached below.
A system of equation or simultaneous equations are a pair of linear equation is 2 variables such that they represent a pair of straight line sin the cartesian plane.
The point of intersection of these two line on the cartesian plane is given by the solution of the two equation that are given.
A system of equations can be solved algebraically by matrix method , elimination method or by substitution.
Now let us solve the given equation algebraically by elimination method.
5x - y = 35
3x + y = -3
Adding the equation we get:
or, 8 x = 32
or, x = 4
putting the value of x in the first equation we get:
5 × 4 - y = 35
or, -y = 35 - 20
or, y = -15
Hence the point of intersection is ( 4 , -15 )

please, it’s for tomorrow and i need whit the process
a) for given functions f(x) = 8x and g(x) = 12x + 3,
(f g)(x) = 96x² + 24x
b) for functions f(x)= 14 and g(x)= 3 - 12x,
f(x) • g(x) = 42 - 168x
In this question, we have been given two functions.
We need to find the given function.
a) f(x) = 8x and g(x) = 12x + 3
To find (f g)(x)
We know that, the product of functions f(x) and g(x) is:
(f g)(x) = f(x) . g(x)
(f g)(x) = (8x) (12x + 3)
(f g)(x) = 96x² + 24x
So, for given functions f(x) = 8x and g(x) = 12x + 3,
(f g)(x) = 96x² + 24x
b) f(x)= 14 and g(x)= 3 - 12x
To find f(x) • g(x)
f(x) • g(x) = (14) . (3 - 12x)
f(x) • g(x) = 42 - 168x
So, for functions f(x)= 14 and g(x)= 3 - 12x,
f(x) • g(x) = 42 - 168x
Therefore, a) for given functions f(x) = 8x and g(x) = 12x + 3,
(f g)(x) = 96x² + 24x

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

c. Would the sum of the interior angles of a triangle in this type of geometry be different from those of triangle in Euclidean geometry? Explain.
The fact that the sum of the interior angles of a triangle add up to 180 is equivalent to the parallel postulate. Therefore, the sum of the interior angles of a triangle in this type of geometry be different from those of triangle in Euclidean geometry.
How to illustrate the information?There is only one parallel to the given line in Riemannian geometry. A straight line of finite length that can be continued endlessly is the second postulate of Euclid.
One of the non-Euclidean geometries that entirely rejects the validity of Euclid's fifth postulate and alters his second postulate is Riemannian geometry, commonly known as elliptic geometry. The fifth postulate of Euclid states that there is only one line that passes through a point that is not on a particular line and is parallel to that line.

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

Malia uses 51 yards of ribbon to make 17 bows. the relationship between ribbon and bows is proportional. how many yards of ribbon does malia need to make 68 bows?
Malia that uses 51 yards of ribbon to make 17 bows will have to use 204 yards of ribbon to make 68 bows
To solve this problem we will use a rule of three with the problem information:
17 bows-------- 51 yards of ribbon
68 bows-------- x
Applying the rule of three we get:
x = (68 bows * 51 yards of ribbon) /17 bows
x = 204 yards of ribbon
