Step-by-step explanation:
f(x) = x² + 2x - 4
g(x) = 3x + 1
f(g(x)) = f(3x + 1)
f(3x + 1) = [3x + 1]² + 2[3x + 1] - 4
= 9x² + 6x + 1 + 6x + 2 - 4
= 9x² + 12x -1

Is it true that square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol?
Answer:
Yes
Step-by-step explanation:
I had this same question on a quiz and it is correct!
The square root of a number is equal to another number that when squared is equal to the original number.
Now we want to see if Is it true that square roots can be compared and ordered by comparing and ordering the numbers underneath the radical symbol, and we will see that yes, this is true.
To see that this is true:
For example, if the A and B are two numbers larger than 0, such that:
A > B
Then:
√A > √B
For example let's use A = 9 and B = 4.
9 > 4
And obviously the roots are:
√9 > √4
3 > 2
So yes, we can compare and order square roots by comparing the numbers inside of it.

4x+9y=28
-4x-y=-28
Step-by-step explanation:
4x+9y=28
-4x-y=-28
8y=0
divide both side by 8
y=0
solve for X in equation 1
4(X)-9(0)=28
4x-0=28
4x =28
divide both side by 4
4x/4=28/4

what is the smallest two digit positive integer such that the product of its two digits is one-half the integer
Let x be the tens and y be the ones digits.
The product of the number is then: 10x + y
The product is 1/2, so you need to multiply the product by 2 and the number:
10x + y = 2(x+y)
10x + y = 2x + 2y
Subtract 1 y from both sides
10x = 2x + y
Subtract 2x from
Both sides
8x = y
X has to be 1 , which would make y 8
The product number becomes 18
Since the product is 1/2, multiply by 2:
18 x 2 = 36
3 x 6 = 18
The answer is 36

Solve for f.
Round your answer to 2 decimals.
9f = {(12f – 2)
Answer:
f=0.67
Step-by-step explanation:
Let's solve your equation step-by-step by isolating f.
9f=12f−2
Step 1: Subtract 12f from both sides.
9f−12f=12f−2−12f
You get:
−3f=−2
Step 2: Divide both sides by -3.
−3f/−3 = −2/−3
You get:
f= 2/3, or f= 0.67

What is the value of y in the equation 5x + 2y = 20, when x = 0.3?
Answer:
9.25
Step-by-step explanation:
5(0.3) = 1.5
20-1.5=18.5
18.5÷2=9.25
Answer:
y = 9.25Step-by-step explanation:
5x + 2y = 20
when x = 0.3 we have
5(0.3) + 2y = 20
1.5 + 2y = 20
Using the subtraction property subtract 1.5 from both sides of the equation
That's
1.5 - 1.5 + 2y = 20 - 1.5
2y = 18.5
Divide both sides by 2
[tex] \frac{2y}{2} = \frac{18.5}{2} [/tex]
We have the final answer as
y = 9.25Hope this helps you

the number 102 is NOT a term in this sequence. explain why.
thanks :)
Answer:
common difference = 4
if 102 is a term in sequence n should have non decimal value
a +(n-1)d = 102
0r 6 + (n-1)4= 102
0r, 4(n-1) = 96
or n-1 =24
n =25
102 is in a sequence
