Answer:
277
Step-by-step explanation:
14^2+5(14)+11=
196+70+11=
277
Start by substituting 14 in for x everywhere that x appears in the problem.
So we have (14)² + 5(14) + 11.
Remember that PEMDAS tells you to deal
with your exponents before multiplying.
So you must square the 14 to get 196.
So we have 196 + 5(14) + 11.
Now multiply 5(14) to get 70.
So we have 196 + 70 + 11.
Now we can simply add to get 277.

Answer:
x=-1, x=3
Step-by-step explanation:
to solve by factoring:
1. swap the sides:
0=(x-1)^2-4
2. expand the expression:
(x-1)^2-4=0
3. rewrite and calculate:
x^2-2x+1-4=0
4. factor
x^2+x-3x-3=0
5. Factor... again
x(x+1)-3(x+1)=0
6. separate
(x+1) (x-3)=0
7. solve
x+1=0, x-3=0

which figures show that M is a midpoint? select all that apply.
Step-by-step explanation:
a D&C show that m is the midpoint
The required figures that show the mid-points are (c) and (d).
A midpoint is a point on the line whose distance from both ends of the line is equal.
Here,
Figures are shown where in figure (A) only point M is shown which does not describe itself. In figure (B) M is located so far from B and there is no point on the other side of M. In figure (C) and (D) Point M is located between two certain points with equal measures.
Thus, the required figures that show the mid-points are (c) and (d).

(02.04 MC) Your friend has $90 when he goes to the fair. He spends $5 to enter the fair and $15 on food. Rides at the fair cost $1.50 per ride. Which function can be used to determine how much money he has left over after x rides? f(x) = 1.5x + 70 f(x) = −1.5x + 70 f(x) = −1.5x − 70 f(x) = −20x + $90
Answer:
f(x)= $70 - $1.5*x
Step-by-step explanation:
You know your friend spends $ 5 to enter the fair and $ 15 for food. So the total you spent is given by:
$5 + $15= $20
Knowing that the trips at the fair cost $ 1.50 per trip, and with x being the number of trips, then the cost after x trips will be:
$1.5*x
So the money spent after x rides can be expressed as:
$20 + $1.5*x
Knowing that your friend has $90 when he goes to the fair, to calculate the amount of money he has left after x rides, the amount taken to the fair and the amount spent is subtracted:
$90 - ($20 + $1.5*x)
$90 -$20 -$1.5*x
$70 - $1.5*x
By calling the function f(x) used to determine the amount of money left after x trips, you can finally express:
f(x)= $70 - $1.5*x
P = R - C solve for C
Answer:
C = R - P
Step-by-step explanation:
Step 1: Write equation
P = R - C
Step 2: Subtract R on both sides
P - R = -C
Step 3: Divide both sides by -1
-P + R = C
Step 4: Rewrite
C = R - P
Answer:
C=R-P
Step-by-step explanation:
First move your terms
C+P=R then move variable to the right-hand side
C=R-P is your solution

Each sheep has 4 legs and each chicken has 2 legs. If a farm boy counts 50 heads and 140 feet, how many sheep are there?
1. 30 sheep
2. 20 sheep
3. 10 sheep
Answer:
20
Step-by-step explanation:
H+S=50
2H+4S=140
4H+4S=200
4H+4S=200-
2H+ 4S =140
2H=60
H=30
50-30=20
Given:
Each sheep has 4 legs and a chicken has 2 legs.
A farm boy counts total heads = 50
And number of legs = 140
To Find:
Number of sheep.
Solution:
Let the number of sheep in the farm = s
And the number of chicken in the farm = h
If the total number of heads = 50
s + h = 50 ------- (1)
If the total number of the legs = 140
Number of legs of 's' sheep = 4s
Number of legs of 'h' chicken = 2h
Therefore, 4s + 2h = 140
2s + h = 70 -------(2)
Subtract equation (1) from equation (2),
(2s + h) - (s + h) = 70 - 50
s = 20
Therefore, 20 sheep are in the farm.

Solve for z.
A= x + 5 + Z
Answer:
Z = A - x - 5
Step-by-step explanation:
A = x + 5 + z
Make the equation equal to z by moving the x and 5 to the side of the = with A. Move the x and 5 by subtracting x and 5 from both sides.
A - x = 5 + z
A - x - 5 = z
So, Z is equal to A - x - 5
Triangle ABC is located on a coordinate plane. Angle C is at (1, 2). The triangle is rotated counterclockwise 90° about the origin. HOW DO I SOLVE THIS????
Answer:the answer is (-2,1)
Step-by-step explanation:
When rotating a point 90 degrees counterwise about the origin point (x,y) becomes (-y,x). So basically switch x and y and make y negative when rotating 90 degrees counterclockwise about the origin.
If the triangle is rotated counterclockwise 90 degrees about the origin, the angle C = (1, 2) will become C = (-1, 2).
What is a triangle?
It is a two dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Triangle ABC is located on a coordinate plane.
Angle C is at (1, 2).
This means that,
Angle C = (1, 2) is in the I Quadrant.
We have four Quadrant:
Quadrant I - The coordinates are in the form of (x, y)
Quadrant II - The coordinates are in the form of (x, -y)
Quadrant III - The coordinates are in the form of (-x, -y)
Quadrant IV - The coordinates are in the form of (-x, y)
If we rotate C = (1, 2) counterclockwise 90 degrees about the origin, the angle C will be in the IV quadrant.
So,
C = (1, 2) will become C = (-1, 2)
Thus,
If the triangle is rotated counterclockwise 90 degrees about the origin, the angle C = (1, 2) will become C = (-1, 2).
