5y=45 if y=9
Step-by-step explanation:
5y=45 if y=9
5(9)=45
45=45
3x+3y=9 solve for y
Can the answer be written as y=-x+3 my teacher told me I can write it like that can I though ? Or is the answer y=-x 3 ?

Answer:
5 (-9x)
Step-by-step explanation:
Product of 5
5 * ()
difference of 9
5 * (-9)
and a number
5 * (-9x)
Answer:
5(9 - x)
Step-by-step explanation:
The product of 2 numbers, is just multiplication
But in this expression, we are multiplying a number by the difference of two other numbers, hence why we should group 9 - x in parentheses.

A small town has two local high schools. High School A currently has 850 students
and is projected to grow by 35 students each year. High School B currently has 700
students and is projected to grow by 60 students each year. Let A represent the
number of students in High School A int years, and let B represent the number of
students in High School B after t years. Write an equation for each situation, in terms
of t, and determine after how many years, t, the number of students in both high
schools would be the same.
Answer:
For High School A, let [tex]S_A(t)[/tex] denote the number of students after [tex]t[/tex] years. Define [tex]S_B(t)[/tex] analogously.
Then [tex]S_A(t) = 850 + 35t[/tex] and [tex]S_B(t) = 700 + 60t[/tex].
After 6 years the number of students in both high schools would be the same.
Step-by-step explanation:
For High School A, let [tex]S_A(t)[/tex] denote the number of students after [tex]t[/tex] years. Define [tex]S_B(t)[/tex] analogously.
Since we start out at 850 students at High School A and it is growing by 35 students every year, we must have that [tex]S_A(t) = 850 + 35t[/tex].
Since we start out at 700 students at High School B and it is growing by 60 students every year, we must have that [tex]S_B(t) = 700 + 60t[/tex].
Setting the two equations equal to each other, we see that [tex]850+35t=700+60t\\850-700=60t-35t\\25t=150\\t=6[/tex]
So after 6 years the number of students in both high schools would be the same.
Find the unknown measures. Round lengths to the nearest hundredth and angle measures to the nearest degree.
Answer:
AB = 4.62 m∠A = 22° m∠B = 68°
Step-by-step explanation:
Tan A = 1.7/4.3 = .39534...
m∠A = arctan .39534... ≅ 22°
m∠B = 90 - 22 = 68°
AB = [tex]\sqrt{1.7^{2} + 4.3^{2} } = \sqrt{2.89 + 18.49} = \sqrt{21.38} = 4.62[/tex]

Factor the expression using the GCF 7+14
Answer:
We found the factors and prime factorization of 7 and 14. The biggest common factor number is the GCF number. So the greatest common factor 7 and 14 is 7.
Step-by-step explanation:
The value of the Expression 7+ 14 using the GCF is 21.
What is Greatest Common Factor?The largest factor that splits both numbers is said to be the greatest common factor. List the prime factors of each integer before calculating the greatest common factor. One 2 and one 3 are shared by those aged 18 and 24. The GCF of 18 and 24 is 2 * 3 = 6, which we multiply to obtain.
Given:
We have to add 7 + 14
Factorise the terms separately
7 = 7 x 1
14 = 7 x 2
So, the Greatest Common Factor is 7.
Thus, 7+ 14 = 7(1+ 2) = 7 x 3= 21

How many terms are in the expression 2a - c + 7d+ 15
Answer:
8c
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
I just want to tell you what a term is because your going to really need it when you go into middle school. So a term is where there is a number or a a number with a variable with it or a variable by itself. For example if there is 4x + 6m + 3 + X you would have 4 terms because you have 4 numbers along with variables and a variable by itself and with some numbers which are Co -Efficient. Co-Efficient is when a number is with a variable the number along with the variable is called a Co-Efficient. Both of them together is called a term so now you know :) The whole equation is called an expression if a a number is by itself like 4 + 3m the 4 would be considered as a constant because its just a normal number standing by itself.

Find cos(B) in the triangle.
Step-by-step explanation:
[tex] \cos( \beta ) = \frac{5}{13} = 0.385[/tex]
Cos (B) in the right angled triangle is 5/13 .
Given,
Right angled triangle .
Now,
In right angled triangle
Perpendicular = 12
Base = 5
Hypotenuse = 13
So,
According to trigonometric functions,
CosФ = base / hypotenuse
sinФ = perpendicular / hypotenuse
tanФ = perpendicular / base
So,
Substitute the value in the function of cos,
Cos(B) = base / hypotenuse
Cos(B) = 5 / 13
Thus the value of function cos (B) is 5/13 .
