What is f(6)?
f(x) = 5x - 2
Answers
Answer:
f(6) = 28
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
FunctionsFunction NotationStep-by-step explanation:
Step 1: Define
f(x) = 5x - 2
f(6) is x = 6
Step 2: Evaluate
Substitute in x [Function]: f(6) = 5(6) - 2Multiplication: f(6) = 30 - 2Subtraction: f(6) = 28=========================================================
Explanation:
Everywhere you see an x, replace it with 6
f(x) = 5x - 2
f(6) = 5*6 - 2
f(6) = 30 - 2
f(6) = 28
Remember that 5x is the same as 5*x or "5 times x". So that's why 5x turned into 5*6 after replacing x with 6. After every x is replaced, you follow the order of operations PEMDAS to simplify.

Answer:
10x+3, or 2x+12, or [tex]x^{2}[/tex]+12x+27
Step-by-step explanation:
If the equation is x + 9x + 3, combine like terms you get 10x+3
If the equation is x+9 + x+3, combine x and numbers (like terms) and you get 2x+12
If the equation is (x+9)(x+3) or it is asking you to multiply, multiply x by x, and 9 by x, and 3 by x, and 9 by 3. Add them all up (like terms) and you get [tex]x^{2}[/tex]+12x+27.

Let get x as a number of small circles.
Area of big circle = Area of all small circles
(Here . implies multiplication)
22/7 . 35 cm .35cm = 22/7 . 7cm .7cm .x
x = (22/7 . 35 cm .35cm) / (22/7 . 7 cm .7cm)

Given
[tex]Days = 2[/tex]
[tex]Rent = 3500[/tex] daily

Mary always saved 45% of his salary. When his salary decreased by 20% in April, his savings decreased by $180.
How much was Mary’s salary before the decease?
Answers
Answer:
Step-by-step explanation:
Answer:
Is Mary a guy? :|
Step-by-step explanation:
I did this by just a good guess , not really the right way
2000*.45=900 ( 900 is the old savings)
2000*.2 =400 ( how much her salary went down by )
2000-400=1600 ( new salary )
1600*.45 = 720 ( 45% of new salary is new savings
900-720=180 ( change in savings is 180 , the amount the question asks for)
Mary's old salary was 2,000
{1800*(-90)} /495/(-22)

The ratio of boys to girls in a class is 5:7. There are 36 students in the
class. How many more girls than boys are there?
Answers
Answer: number of girls = 21 & number of boys = 15
21 - 15 = 6 ( the difference is 6 )
Step-by-step explanation:
Answer:
add the ratios together. this gives 5+7 which is 12. divide 36 by 12, this gives 3. this tells us it's three students for every value of the ratio, so the ratio is 5(3):7(3). it becomes 15 boys to 21 girls. to find out how many more girls, we subtract 15 from 21. our answer is 6.

3) [tex]x^{2}[/tex] + 4x - 21
Step-by-step explanation:
(x - 3)(x + 7)
Distribute:
x(x + 7)
-3(x + 7)
x(x) = [tex]x^{2}[/tex]
x(7) = 7x
-3(x) = -3x
-3(7) = -21
Combine like terms:
7x - 3x = 4x
Put it together:
[tex]x^{2}[/tex] + 4x - 21
Answer: x²+ 4x - 21
Let's do this step-by-step.
1. Apply the foil method. (formula: (a + b)(c + d) = ac + ad + bc + bd)
F - First
O - Outer
I - Inner
L - Last
= xx + x × 7 + (-3)x + (-3) × 7
2. Apply the minus and plus rules. + (-a) = -a
xx + 7x - 3x - 3 × 7
3. Simplify.
Convert xx into a exponent.xx ⇒ x²Subtract 7 by 3.7x - 3x = 4xMultiply 3 by 7.7 × 3 = 21Hence, the answer is x² + 4x - 21
