Answer:
f(3) = 10
Step-by-step explanation:
If x = 3 then fill in the x's on the original equation and solve;
f(x) = 2x + 4
f(3) = 2(3) + 4
2 x 3 = 6
6 + 4 = 10
So, f(3) = 10

George has $15. He would like to know if he has enough money to see a movie ($9.00) and buy a pretzel ($2.65), a drink ($1.35 ), and two veggie cups ($1.74 each). George incorrectly used this numerical expression to decide if he had enough money.
Answer:
He does not have enough money
Step-by-step explanation:
Step one:
given data
The total money that Goerge has is $15
Expenses to incure
to see a movie ($9.00) and
to buy a pretzel ($2.65),
a drink ($1.35 ), and
two veggie cups ($1.74 each)= 1.74*2= $3.48
Totoal expenses= 9+2.65+1.35+3.48= $16.48
Step two:
The deficit that George will have is 16.48-15= $1.48
Hence he does not have enough money
Answer:
13.48

2) They distributed an x out of the term with out one. that is the 8
so the expression should be 5x +8
3) They didn't follow order of operations and took 2 away from the 7 before they distributed the 7 :O very bad of them
the expression should be 7x + 54
4) They distributed out the y but didn't leave a 1 so the problem lost a term.
the expression should be -6x + 7y

Classify the following triangle as acute, obtuse, or right.
OA. Obtuse
OB. Acute
OC. Right
OD. None of these
The triangle is an acute triangle
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of angles of the triangle are
The measure of ∠ABC = 50°
The measure of ∠BAC = 50°
The measure of ∠ACB = 80°
So , all the angles of the triangle are less than 90°
So , it is an acute triangle
Hence , the triangle is acute

What is a polynomial?A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.
The polynomial is given as,
P(x) = x³ - 28x - 48
Let's check if x + 4 = 0 is a factor or not. Then we have
x + 4 = 0
x = - 4
At x = -4, the value of the polynomial is given as,
P(x) = (-4)³ - 28(-4) - 48
P(x) = - 64 + 112 - 48
P(x) = - 112 + 112
P(x) = 0
The remainder of the polynomial P(x) = x³ - 28x - 48 will be 0. Then the correct option is D.

Step-by-step explanation:
For the equation to have more than one solution, that is infinite solutions, then both sides should be equal.
left side is
5u + 3(4u - 6)
= 5u + 12u - 18 = 17u - 18
right side is
- 3u - 27 + 20u
= 17u - 27 ← require to add 9 so equal to left side, that is
17u - 27 + 9
= 17u - 18

Step-by-step explanation:
2x + y = 8 is the equation of a straight line. ... By substituting y = 0 into the equation we will find the corresponding x-coordinate at this point. y = 0 : 2x = 8 and so x = 4 hence point (4 , 0 ) on the x-axis

Answer:
-500
Step-by-step explanation:
(2a^4)^2
-----------------
a^0 a^5
We know ( xy) ^z = x^z y^z
so
(2a^4)^2 = 2^2 a^4^2
and x^y^z =x^(y*z) so a^4^2 = a^(4*2) = a^8
(2a^4)^2 = 4 a^8
We know that a^0 = 1
4 a^8

1 a^5
We know x^y / x^z = x^ ( y-z)

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation in the standard form is given below.
3x + 2y - 1 = 0
Separate 'y', then we have
3x + 2y - 1 = 0
2y = -3x + 1
y = -(3/2)x + 1/2

Describe how the graph of y= x^2 can be transformed to the graph of the given equation.
y = (x - 12)^2 + 3 (5 points)
a) Shift the graph of y = x2 up 12 units and then right 3 units.
b) Shift the graph of y = x2 left 12 units and then down 3 units.
c) Shift the graph of y = x2 left 12 units and then up 3 units.
d) Shift the graph of y = x2 right 12 units and then up 3 units.
Answer:
We conclude that the graph y = x² can be transformed into the graph of the given equation y = (x - 12)²+3 by shifting the graph of y = x² right 12 units and then up 3 units.
Hence, option D is true.
Please check the attached graph.
Step-by-step explanation:
Given the parent function
y = x²
Given the transformed function
y = (x - 12)²
Horizontal Translation:
The horizontal translation of y = x² is of the form
f(x-h)
so y = y = (x - 12)² means y = x² is shifted 12 right.
Vertical Translation:
y = x²
Then y = x² + b is a vertical translation of y = x²
if b > 0, then y = x² + b is the graph of y = x² 'b' units up.
if b < 0, then y = x² + b is the graph of y = x² 'b' units down.
Thus, y = x² + 3 means the graph y = x² is vertically shifted up by 2 units.
Please check the attached graph.
The blue graph is representing the graph of y = x². The red graph is representing the graph of y = (x - 12)²+3Therefore, the graph y = x² can be transformed into the graph of the given equation y = (x - 12)²+3 by shifting the graph of y = x² right 12 units and then up 3 units.
Hence, option D is true.
Answer:
Shift the graph of y = x2 right 12 units and then up 3 units.

film processing costs $4.95, plus $0.35 for each picture printed. Milan paid $11.95 for processing and printing. How many pictures did he have printed?
Answer:
20 pictures.
Step-by-step explanation:
In this question, we need to find out how many pictures Milan printed.
We know that the film processing costed $4.95 and each picture that was printed costed $0.35.
Lets turn this into an equation with x representing the amount of pictures:
y = 0.35x+ 4.95
Now we need to solve the equation. We can do this by plugging in our known cost, 11.95, into "y".
Solve:
11.95 = 0.35x + 4.95
Subtract 4.95 from both sides.
7 = 0.35x
Divide both sides by 0.35
20 = x
Milan printed 20 pictures.
