Answer:
f(-4)=3(-4)+7=0
f(2)=3(2)+7=13
Answer:
Step-by-step explanation:
f(x) = 3 x+7
f(x) = 3 x + 7
f(-4) = 3*-4 + 7
f(-4) = -12 + 7
f(-4) = -5
f(x) = 3 x + 7
f(2) = 3*2+7
f(2) = 6 + 7
f(2) = 13.
:f(-4) =-5 , f(2) =13

Answer:
first multiply 3 with −8 and we get − 24
then find two numbers that if we add or subtract we get + 10 and if we multiply we get − 24
and the numbers are + 12 and −2
then we place those numbers as follow :-
3x²+12x−2x−8
then we group them
(3x2+12x)(−2x−8)
now take the common factor out.
3x(x+4)−2(x+4)
then group the numbers outside of the brackets
(3x−2)(x+4)
And that is the answer:
Proper Solution:-
1.) 3x2+10x−8
2.) 3x2+12x−2x−8
3.) (3x2+12x)(−2x−8)
4.) 3x(x+4)−2(x+4)
5.) (3x−2)(x+4)
How many solutions does the following system of equations have?
{4x + 6y = 24
2x + 3y = 12
Answer:
Infinitely many solutions
Step-by-step explanation:
Note that 2(2x+3y=12) is 4x+6y=24, which is the first equation. Therefore, by canceling the equations out, you have 0=0, which means whatever one side equals, the other side ALWAYS equals that.

there were a total of 35 football games in the season the season is played for five months how many football games were played each month if each month has the same number of games
Answer:
7
Step-by-step explanation:
35/5=7
Hope this helps!
Answer: We know that there is 35 games per season and is played throughout 5 months. If in each month the same number of games were played we would have to do 35/5 which is equal to 7. To check your work you can do 5 times 7 which is 35. Remeber opposite of division is multiplication and opposite of multiplication is division. SO, your answer is 7 football games per month.

A pet store has 15 birds and 75 fish.
In simplest form, what is the ratio of birds to fish in the pet store?
O1/6
O1/5
O5/1
I don't know
Answer:
1/5
Step-by-step explanation:
For every bird in the store there will be 5 fish.
Because there is 5 times more fish then birds.
Using the ratio concept, the number of birds to fish expressed as a ratio is 1/5
Given the Parameters :
Number of birds = 15 Number of fishes = 75Ratio of the number of birds to fish can be expressed thus :
Number of birds : Number of fishes15 : 75
Divide both sides by 15
1 : 5
Hence, the ratio of birds to fish is 1/5

Transpose for p
w = p + cg
Make h the subject
m = r - h + 4d
The result of making the required variable the subject in both equation are :
p = w - cgh = - (m - r - 4d)Making p the subject in w = p + cg :
w = p + cg
Subtract cg from bith sides
w - cg = p + cg - cg
p = w - cg
2.)
Make h the subject m = r - h + 4d
m = r - h + 4d
Subtract r from both sides
m - r = r - h + 4d - r
m - r = - h + 4d
Subtract 4d from both sides
m - r - 4d = - h
Divide both sides by - 1
h = - (m - r - 4d)

[tex]\sqrt{x^{2}-16 }-3\sqrt{x-4}=0[/tex]
Answer:
[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 \\ [/tex]
Step-by-step explanation:
[tex]\tt{} \sqrt{ {x}^{2} - 16 } - 3 \sqrt{x - 4} = 0[/tex]
[tex]\tt{} \sqrt{ {x}^{2} - 16 } = 3 \sqrt{x - 4} [/tex]
[tex]\tt{}{x}^{2} - 16 = 9(x - 4)[/tex]
[tex]\tt{}(x - 4).(x + 4) = 9(x - 4)[/tex]
[tex]\tt{}(x - 4) \times (x + 4 - 9) = 0[/tex]
[tex]\tt{}( x - 4) \times (x - 5) = 0[/tex]
[tex]\tt{}x - 4 = 0 \\ \tt{}x - 5 = 0[/tex]
[tex]\tt{}x = 4 \\ \tt{}x = 5 \\ \\ [/tex]
[tex]\tt{} x_{1} = 4 \\ \tt{} x_{2} = 5 [/tex]
Answer:
x = 4, 5.
Step-by-step explanation:
√(x^2 - 16) - 3√(x - 4) = 0
√(x^2 - 16) = 3√(x - 4)
Square both sides of the equation:
x^2 - 16 = 9(x - 4)
x^2 - 9x - 16 + 36 = 0
x^2 - 9x + 20 = 0
(x - 4)(x - 5) = 0
x = 4, 5.
As the original equation contained square roots:
We test for extraneous solutions:
x = 4:
√(4^2 - 16) - 3√(4 - 4) = 0 - 3*0 = 0 so x = 4 is OK.
x = 5:
√(5^2 - 16) - 3√(5 - 4) = √9 - 3√1 = 0 so x = 5 is also OK.
