What is f(6)?
f(x) = 5x - 2
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:
Step-by-step explanation:
how many shapes of size A are in B ?
I counted 9.5
then just multiply the count * the size of A
got it?
Step-by-step explanation:
area of shape A = 3cm²
number of A shape in shape B = 9 and half
1 shape A = 3cm²
9 shape A = 3×9 = 27cm²
1 half shape A = 3 ÷ 2 = 1.5cm²
area of shape B = 27cm² + 1.5cm² = 28.5cm²

Every episode is 20 minutes. The points would be:
(40, 2)(80, 4)(120, 6)(160, 8){1800*(-90)} /495/(-22)
What are the slope and y-intercept of the line?
A scatterplot with about 20 points plotted in an upward trend along with a line of best fit that begins at the point zero comma 2 and passes through the point 4 comma 7 point 2.
The slope is approximately 3 and the y-intercept is 2.
The slope is approximately 1.33 and the y-intercept is 2.
The slope is approximately 2 and the y-intercept is 3.
The slope is approximately 2 and the y-intercept is 1.33.
Answer:
i think it would be B.The slope is approximately 1.33 and the y-intercept is 2.
it would be more clear if you put a graph :)
How
Many small circles of radius 7cm
can be got from big
big circle of radius
35cm
Answer:
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)
x = (35 . 35) /(7.7)
x = 25

It is possible for a system of linear equations to have exactly 2 solutions.
Answer:
Number of Solutions
Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it's the only one.

Answer:
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

Answer:
A = 54.11 unit²
Step-by-step explanation:
Given that :
A = θ/360 * πr²
A = 62/360 * π(10)²
A = 0.1722222 * π * 100
A = 54.105206
A = 54.11 unit²

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?
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

10. In how many ways can a student select 7 out of 10 questions to work on an exam
Answer:
Step-by-step explanation:
7C10 = 10!/(7!)(10-7)!
7C10 = 10!/(7!)(3!)
7C10 = (10 x 9 x 8 x 7)/(7 x 6 x 5)(6)
7C10 = (10 x 9 x 8)/6
7C10 = 720/6
7C10 = 120
Answer: 120 ways
