Answer:
(f + g)(x) = 2x² + x - 5
Step-by-step explanation:
Given
[tex]f(x) = -2[/tex]
[tex]g\left(x\right)\:=\:2x^2+\:x-3[/tex]
To determine
(f + 9)(x) = ?
Using the formula
(f + g)(x) = f(x) + g(x)
substituting f(x) = -2 and g(x) = 2x² + x - 3
= -2 + 2x² + x - 3
= 2x² + x - 5
Therefore, we conclude that:
(f + g)(x) = 2x² + x - 5

If Log 20 = 1.301 what is the value of Logsub100 20?
I need the step by steps! I can’t find anything videos online to teach this to me
Answer:
[tex]log_{100}20 = 0.6505[/tex]
Step-by-step explanation:
log20 = 1.301 (when you see only "log" with no base, it is taken as a base 10)
This basically means:
[tex]10^{1.301} = 20[/tex] (This is the log in exponential form)
Since we don't know what [tex]log_{100}20[/tex] is equal to, we will say [tex]log_{100}20[/tex] = x
So to solve for [tex]log_{100}20[/tex] = x, you do the same thing. (convert to exponential form)
[tex]100^{x} =20[/tex]
Now you will notice that both of these equations are equal to 20.
Since 20 = 20,
we can say [tex]100^{x}[/tex] = [tex]10^{1.301}[/tex]
Another way of saying 100, is [tex]10^{2}[/tex] (make the bases the same)
Now we get [tex]10^{2x} = 10^{1.301}[/tex]
(we get 2x because an exponent to the power of an exponent ([tex]2^{x}[/tex]) is the same as 2 * x)
Because you have the same base, you can just ignore the 10s and focus on the exponents. So you get:
2x = 1.301
x = 0.6505

Answer: 0.56 as a decimal 56% as a percentage
Step-by-step explanation:
Anita made these two statements.
The number 2 is its own opposite.
The opposite of the opposite of 1.5 is 1.5
Fill in the blanks to explain whether theses statements are true or false.
The opposite of 2 is
Step-by-step explanation:
umm its false cause one thing isn't correct here.
like if we're asked to find the opposite of -5 itll be +5
and in Anita's case, she should have said, that the like for 2 the opposite will be -2 like just change the integers.
like for -, change it to positive and for +, change it to negative

If 2^3x-1 = 32 then x = (image included)
a. 5
b. -2
c. 2
d. 4/3
e. -4
Answer:
x is equal to two.
Step-by-step explanation:
We know that 32 is a power of 2. It is in fact two to the power of five. So we can re-express that as:
[tex]2^{3x - 1} = 2^5[/tex]
Because they have the same constant as a base, we can toss the base altogether, and equate the exponents:
[tex]3x - 1 = 5\\3x = 6\\x = 2[/tex]
Which linear function represents the line given by the point-slope equation y + 7 = -2/3 (x+6)?
O f(x) = -x-11
O fx) = x-1
O f(x) = 2x+3
O fx) = 2x + 13
Answer:
A- f(x) -x-11
Step-by-step explanation:
The top equation y+7= -2/3(x+6) has a
Y-intercept of (0,-11)
Slope=-2/3
Answer A has the the same
y-intercept (0,-11)
Slope of -1
Answer is the only one with the same y-intercept.
15-a=20 what value would make this true
Answer:
a = -5
Step-by-step explanation:
15 - a = 20
Move the constant of 15 to the other side by subtracting it.
-a = 5
Divide by -1 to make a positive.
a = -5
Check.
15 - (-5) = 20
15 + 5 = 20
20 = 20
Answer:
-5
Step-by-step explanation:
15-(-5)=20
5 turns into a positive
15+5=20
What does k equal?
As in y=kx

When the balloon touched the wall, it stayed there. What is the best explanation for the balloon staying on the wall?
Answer:
When the negatively charged balloon approaches a wall, the negative charges in the wall are repelled (or pushed away)
Step-by-step explanation:
As the two come in contact, the balloon will stick because of the rule that opposites attract (positive to negative)

If f(x) = x^2 + 7x and g(x) = 3x - 1, what is f(g(x))?
O 9x2 + x + 1
9x2 + 15x - 6
9x2 + 21x-6
9x2 - 27x
Help please
Answer:
9x^2 + 15x -6
Step-by-step explanation:
Your problem → If f(x) = x^2 + 7x and g(x) = 3x - 1, find f(g(x))?
f(x)=x2+7x,g(x)=3x-1,fog(x)=?
g(x)=3x-1,f(x)=x2+7x
fog(x)=f(g(x))
=f(3x-1)
=(3x-1)2+7⋅(3x-1)
=(3x-1)2+21x-7
=(9x2-6x+1)+21x-7
=9x2+15x-6
fog(x)=9x2+15x-6
Let p=x^2-2 which equation is equivalent to (x^2-2)^2+18=9x^2-18 in terms of p
Answer:
The equivalent equation is [tex]p^2 + 18 = 9p[/tex]
Step-by-step explanation:
p is given by the following relation:
[tex]p = x^2 - 2[/tex]
And we are given the following equation:
[tex](x^2 - 2)^2 + 18 = 9x^2 - 18[/tex]
On the right side, we can simplify. So
[tex](x^2 - 2)^2 + 18 = 9(x^2 - 2)[/tex]
Replacing [tex]x^2 - 2[/tex] by p, the equation is:
[tex]p^2 + 18 = 9p[/tex]

Step-by-step explanation:
Find the missing side or angle.
Round to the nearest tenth.
B=18°
C=152°
b=4
c=[ ? ]
Answer:
c = 6.1
Step-by-step explanation:
Given that: B = 18° , C = 152°, and b = 4.
The missing side, c, can be determined by applying the sine rule which states that:
[tex]\frac{b}{Sin B}[/tex] = [tex]\frac{c}{Sin C}[/tex]
[tex]\frac{4}{Sin 18^{o} }[/tex] = [tex]\frac{c}{Sin 152^{o} }[/tex]
c = [tex]\frac{4* Sin 152^{o} }{Sin 18^{o} }[/tex]
= [tex]\frac{1.8779}{0.3090}[/tex]
= 6.0773
c = 6.1
Therefore, the value of the missing side, c, is 6.1
