Answer:
x = - 2
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x)
= x² - 2x + 6x + 4
= x² + 4x + 4
Equating to zero
x² + 4x + 4 = 0 ← left side is a perfect square
(x + 2)² = 0, thus
x + 2 = 0 ( subtract 2 from both sides )
x = - 2
ITS EASY HALP PLEASE
Answer:
Your answer would be B.
Explanation:
You have 1 one hundred and 5 tens which would make 1.50. Next you are adding 6 tens which would be 0.60.
Put these together, and your answer would be 1.50 + 0.60 = 2.10!
Note:
I hope this helps and please correct me if I am wrong. :)

Gaby says that is equivalent to . Do you agree or disagree? Explain your thinking.
Answer:
I do not agree with the student because there is no real solution. Solving the equation only gives possible solutions, but you must check them in the original equation. Checking the solution in the original equation shows that 4 is an extraneous solution.
Step-by-step explanation:
idk if that's the same question i had, but that was the answer for mine. hehehe good luck.

When you multiply the following binomials, what is the linear term (the term with x)?
(X+3) (X-5)
Answer:
We conclude that 2x is the linear term with x.
Step-by-step explanation:
Given the expression
[tex]\left(x+3\right)\left(x-5\right)[/tex]
Multiplying the binomials
Apply FOIL method:
[tex]\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]
[tex]\left(x+3\right)\left(x-5\right)=xx+x\left(-5\right)+3x+3\left(-5\right)[/tex]
Apply +(-) = - rule
[tex]=xx-5x+3x-3\cdot \:5[/tex]
simplify
[tex]=x^2-2x-15[/tex]
Here, 2x is the linear term with x.
It is called a linear term because the exponent of the variable is raised to the power of 1.
In other words, the degree of the linear term is 1.
Therefore, we conclude that 2x is the linear term with x.

How many people i helped proves im right
I don't know what to do.
Answer:
the measure of all the angles within a triangle is = 180 degrees.
the two given angle measures are 70 and 90.
90+70= 160 making the remaining angle = 20 degrees
the two triangles are similar to each other, so they have the same angle measurements. making the measure of angle 1 = 20 degrees
Solve for x. Of the triangle
Answer:
9
Step-by-step explanation:
The total measure of a triagles angle is 180. First do 180-60-75. You should get 45. Next you do 45/5 and you get 9 which is your x value.

Answer:
C = 100 + 40n
The independent variable is n (number of months) and the dependent variable is C ( total cost)
Step-by-step explanation:
Let the total cost of the fitness center = C
Given fixed cost = $100
given cost per month = $40
let number of month = n
The total cost of the fitness center in a given 'n' month is calculated as;
C = 100 + 40n
From the above equation;
the independent variable is n (number of months) and
the dependent variable is C ( total cost)
C = 100 + 40n The independent variable is n (number of months) and the dependent variable is C ( total cost)

This graph shows the amount of charge left on my
computer, c, after I have been awake for h hours.
Enter an equation that
describes the relationship
between c and h.
Submit
Answer:
c= -20h + 90
Step-by-step explanation:
The equation that describes the relationship between c and h is:
[tex]c= -20h + 90[/tex]
We have the graph that shows the amount of charge left on computer, c, after h hours.
Let us consider two points (h, c) on the graph
(0,90) and (4.5, 0)
Now the equation of the line passing through two points
[tex]\frac{c-90}{h-0} =\frac{0-90}{4.5-0} \\c-90=-20h\\c=-20h+90[/tex]
So, the equation that describes the relationship between c and h is:
[tex]c= -20h + 90[/tex]

3x + 5y = -7 slope for this equation
Answer:
I have attached the picture of the slope.
Answer:
slope = - [tex]\frac{3}{5}[/tex]
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
3x + 5y = - 7 ( subtract 3x from both sides )
5y = - 3x - 7 ( divide all terms by 5 )
y = - [tex]\frac{3}{5}[/tex] x - [tex]\frac{7}{5}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{3}{5}[/tex]
Find the value of x. Give reasons to justify your solution. b ∈ ac, d ∈ fa
Answer:
x = 27
Step-by-step explanation:
∠ ABD and ∠ BDE are alternate angles and are congruent, then
∠ BDE = 72°
∠ ADB + ∠ BDE + ∠ EDF = 180° ( sum of angles on a straight line ), that is
2x + 72 + 2x = 180
4x + 72 = 180 ( subtract 72 from both sides )
4x = 108 ( divide both sides by 4 )
x = 27
