If f(x) = 3x +9 x when f(x) = 30
Answer:
[tex]x=5/2[/tex]
Step-by-step explanation:
When [tex]f(x)=30[/tex], we have [tex]3x+9x=30[/tex].
Combining like terms on the right side, we have [tex]12x=30[/tex].
Finally, dividing by [tex]12[/tex] we get [tex]x=30/12[/tex].
We note that [tex]30=6*5[/tex] and [tex]12=6*2[/tex], so [tex]30/12=5/2[/tex].
So, [tex]\boxed{x=5/2}[/tex] and we're done!

Answer:
a. Rosemarie has 16 grandchildren.
b. Each grandchild would receive $0.50 or 50 cents.
Step-by-step explanation:
a. There are 4 sons, and each son has 4 children.
Son 1: 4 children
Son 2: 4 children
Son 3: 4 children
Son 4: 4 children
So you can find the total number of grandchildren by adding up the amount of children each of the sons have: 4 + 4 + 4 + 4 = 16
Rosemarie has 16 grandchildren.
b. If the are $8 total, and it is split equally between Rosemarie's sons, it means each son would get $2 (because $8 / 4 sons = 2).
And then each son would split it between his 4 kids. So $2 / 4 kids = $0.50
Each grandchild would receive $0.50 or 50 cents.

-2 times 3 is -6
-2 times x is -2x
-2 times 1 is -2
the equation now looks like this:
-2x-6=-2x-2-4

x-

-7
-72
Check your work
Write A(x) as the product of linear factors.
Answer:
(x - 7)(x - 4)(x + 4).
Step-by-step explanation:
A(x) = x3 – 7x² – 16x +112
Dividing by x-7:
x^2 - 16 <-------- Quotient
-----------------------------
x-7)x^3 - 7x^2 - 16x + 112
x^3 - 7x^2
0 - 16x + 112
- 16x + 112
..............
so A(x) = (x - 7)(x^2 - 16) x^2 - 16 is the difference of 2 squares so we have:
(x - 7)(x - 4)(x + 4).
Checking by expanding the brackets:
(x - 7)(x - 4)(x + 4)
= x(x - 4)(x + 4) - 7(x - 4)(x + 4)
= x(x^2 - 16) - 7(x^2 - 16)
= x^3 - 16x - 7x^2 + 114
= x^3 - 7x^2 - 16x + 112

Please help! I’ll give brianliest to the correct answer!
Answer:
y = 1.5x + 9
(y = height; x = number of cups)
Step-by-step explanation:
let x = number of cups
let y = height of the stack
the first cup will add 9 to the height (7.5 + 1.5)
so 9 is the y-intercept
for each additional cup, 1.5 will be added
so y = 1.5x + 9

Lines AB and CD are perpendicular to each other. If 3 measures (5x + 2)°, and 4 measures 13°, what is the value of x?
A.
x = 15
B.
x = 77
C.
x = 2
D.
x = 21
Answer:
A is the correct option.
Step-by-step explanation:
Since both lines are perpendicular to each other, that means the sum of their angles is equal to 90°.
Then,
(5x + 2) ° + 13° = 90°
5x + 15° = 90°
5x = 75°
x = 15°

Tim explained a function in words and Paul wrote an equation.
Tim
The amount of money in a savings account increases at a rate of $225 per month. After eight months, the bank account has $4,580 in it.
Paul
y−1,400=56(x+26)
Whose function has the smaller y-intercept?
Tim’s with a y-intercept of $2,700
Paul’s with a y-intercept of $2,856
Paul’s with a y-intercept of $2,800
Tim’s with a y-intercept of $2,780
Answer:
Tim's with a y-intercept of $2,780
Step-by-step explanation:
To find Paul's y-intercept, solve the equation y-1400=56(x+26) for y. Then use the standard format for a linear equation y=mx+b to determine the y-intercept which would be b.
Step 1. Get y by itself by adding 1,400 to both sides.
y-1400 + 1400 = y
56(x+26) + 1400 = 56(x+26) + 1400
New equation y = 56(x+26) + 1400
Step 2. Distribute 56(x+26)
56(x+26) = 56 * x + 56 * 26 = 56x + 1456
New equation y = 56x + 1456 + 1400
Step 3. Simplify.
y = 56x + 2856
Paul's y-intercept would be 2856 because when y=0 x=2856
To Find Tim's y-intercept, subtract 225 * 8 from 4580.
225 * 8 = 1800
4580 - 1800 = 2780

What is the solution to this equation?
7- 3√2-x=12
The value of x is -(5 + 3√2).
what is equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
7- 3√2-x=12
Now solving
7- 3√2-x=12
Subtract 7 from both side
7- 3√2-x - 7 =12 - 7
- 3√2-x = 5
Now, add 3√2 both side
-3√2 -x + 3√2 = 5 + 3√2
-x= 5 + 3√2
x= -(5 + 3√2)
Hence, the value x is -(5 + 3√2).
