What is the value of y in the equation y = 3x - 2, when x = 2
Answer:
y=4
Step-by-step explanation:
3 x 2=6
6 - 2= 4
Answer:
y = 4
Step-by-step explanation:
Equation: y = 3x - 2
Plug in x = 2
New equation: y = 3(2) - 2
Simplify: y = 6 - 2 --> y = 4
Answer: y = 4
Question and choices are in the photo please explain the answer
Answer:
336
Step-by-step explanation:
The exclamation mark in math represents the factorial operation, which means you multiply the number by decreasing positive integers.
Therefore:
5! = 5 x 4 x 3 x 2 x 1 = 120.
8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320
8!/5! = 40320/120
40320/120 = 336
The graph of a function is a parabola that has a minimum at the point (-3,9). Which equation could represent the function?
Well there are no choices listed so it's going to be hard to say which; we'll write an expression for all of them and then give a few instances.
A parabola with a minimum forms a CUP, concave-up positive, meaning the coefficient a on x² must be positive, a>0.
The general form with vertex (p,q) is
y = a(x-p)² + q
So for us, all our parabolas are of the form
y = a(x- -3)² + 9
y = a(x² + 6x + 9) + 9
y = ax² + 6ax + 9(a+1)
That's the general form for a parabola with vertex (-3,9); a>0 assure the parabola has a minimum at the vertex.
Some instances:
a=1 gives
Answer: y = x²+6x+18
a=4 gives
y = 4x² + 24x + 45
Other positive as give other possible answers; without the choices it's impossible to know which one they're seeking.

we subtract 32 from 63 to find OMN
63-32 = 31
Step-by-step explanation:
Answer:
31 degrees
Step-by-step explanation:
The biggest angle is 63 degrees, for find OMN we have to do

In a biscuit tin, there are 10 chocolate and 4 shortbread biscuits. What proportion are, a) Chocolate ?
Answer:
Proportion of chocolate in biscuit tin = 5:7
Step-by-step explanation:
Given:
Number of chocolate in biscuit tin = 10
Number of shortbread biscuits in biscuit tin = 4
Find:
Proportion of chocolate in biscuit tin
Computation:
Proportion of chocolate in biscuit tin = Number of chocolate in biscuit tin / Total product in biscuit tin
Proportion of chocolate in biscuit tin = 10 / [10 + 4]
Proportion of chocolate in biscuit tin = 10 / 14
Proportion of chocolate in biscuit tin = 5:7

SOMEONE PLEASE HELP ME I DONT KNOW HOW TO DO THIS TYPE OF PROBLEM
Answer:
Step-by-step explanation:
Because angles SQR and RQT are central angles, they are congruent to the arcs they intercept. This means that arc SR = 101 and arc RT = 118, making the whole major arc SRT = 219. That means that the minor arc, ST is 360 - 219 which is 141. We are looking in particular for the measure of angle SRT. It just so happens that angle SRT is an inscribed angle, so by definition it is one-half the measure of the arc it intercepts. It intercepts arc ST which we found measures 141, so angle SRT is 141/2 = 70.5
Find the Ares of a semi circle whose radius is 2.4 cm
Answer:
Step-by-step explanation:
area of semi circle=πr^2/2
=3.14*(2.4)^2/2
=3.14*5.76/2
=18.0864/2
=9.0432 cm^2
Answer:
72/25 [tex]\pi[/tex] cm² or 9.047786842... cm²
Step-by-step explanation:
Area of whole circle is [tex]\pi r^{2}[/tex]
[tex]\pi[/tex]×2.4² = 144/25[tex]\pi[/tex] cm² or 18.09557368... cm²
Since it is a semi-circle, divide this value by 2 (or multiply by 0.5, either way, your halving it):
144/25[tex]\pi[/tex] ÷ 2 = 72/25 [tex]\pi[/tex] cm² or 9.047786842... cm²

If f(1)=7 and f(n)=3f(n-1)+3 then find the value of (3)
Given:
[tex]f(1)=7[/tex]
[tex]f(n)=3f(n-1)+3[/tex]
To find:
The value of f(3).
Solution:
We have,
[tex]f(n)=3f(n-1)+3[/tex] ...(i)
Substituting [tex]n=2[/tex] in (i), we get
[tex]f(2)=3f(2-1)+3[/tex]
[tex]f(2)=3f(1)+3[/tex]
Substituting [tex]f(1)=7[/tex] in the above equation, we get
[tex]f(2)=3(7)+3[/tex]
[tex]f(2)=21+3[/tex]
[tex]f(2)=24[/tex]
Now, substituting [tex]n=3[/tex] in (i), we get
[tex]f(3)=3f(3-1)+3[/tex]
[tex]f(3)=3f(2)+3[/tex]
Substituting [tex]f(2)=24[/tex] in the above equation, we get
[tex]f(3)=3(24)+3[/tex]
[tex]f(3)=72+3[/tex]
[tex]f(3)=75[/tex]
Therefore, the value of f(3) is 75.

-3 (7x + 7) = -38 - 4x
Answer:
x = 1
Step-by-step explanation:
-3 (7x + 7) = -38 - 4x
-3(7x)-3(7) = -38 - 4x
-21x - 21 = -38 - 4x
-21x+4x = -38+21
-17x = -17
x = -17/-17
x = 1
Answer:
x = 1.
Step-by-step explanation:
-3(7x + 7) = -38 - 4x
Use distributive property to get:
-21x - 21 = -38 - 4x
Add 4x to both sides to get:
- 17x - 21 = -38
Add 21 to both sides to get:
- 17x = -17
x = 1.

Tomas needs lumber to make corner braces for a piece of furniture he is building. He cuts 4 feet from a board that is 8 feet long. With the wood
he has left, Tomas makes 18 corner braces of equal size. How many inches of wood does each brace use?
Answer:
Each brace uses 2.[tex]\overline 6[/tex] inches of wood
Step-by-step explanation:
The given parameters are;
The length of the board from which he cuts the wood = 8 feet
The length of the wood he cuts from the board = 4 feet
The number of corners on the braces of equal sizes he makes with the wood he has left = 18 corner brace
We have;
The length of the wood he has left = (The length of the board) - (The length of the wood he cuts from the board)
∴ The length of the wood he has left = 8 feet - 4 feet = 4 feet
The length of each brace the man can cuts from the wood he has left = (The length of the wood he has left)/(The number of corner braces he cuts)
∴ The length of each brace = (4 feet)/(18 braces) = (48/18) inches/(braces) = (8/3) inches/brace = 2.[tex]\overline 6[/tex] inches of wood per brace
