Answer:
4x
Step-by-step explanation:
the -8 and +8 cancel out
x and 3x are both positive so add them
you're left with 4x
Simplifying is the same as solving this question. I'll give steps instead.
x - 8 + 3x + 8
x + 3x - 8 + 8 (Arrange the equation)
(x + 3x) (- 8 + 8) (Parentheses the like terms together)
(4x) (0) (Solve)

Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers
cost $0.05 each. How much would Mrs. Algebra's single order be? Use the expression below
to calculate the total.
Given :
Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers cost $0.05 each.
To Find :
How much would Mrs. Algebra's single order be.
Solution :
Total price paid by Mrs. Algebra = Price of pencil + price of ruler + price of calculator + price of eraser.
T = $(0.10 + 0.49 + 12.99 + 0.05)
T = $13.63
Therefore, Mrs. Algebra's single order cost is $13.63 .
Hence, this is the required solution.

Answer:
P(1.5, 3.5)
Step-by-step explanation:
We need to find the average of the x and y coordinates. We do this by adding the two values, then dividing by two:
P(x1 + x2/ 2, y1 + y2/2) = P(1 + 2/ 2, 2 + 5/ 2) = P(3/2, 7/2) = P(1.5, 3.5)
These are our coordinates!
A missile is launched along a path determined by the function below, where f(x) is the height of the missile in feet x seconds after the launch.
A plane is flying nearby at a height of 650 feet.
Is the plane in danger of being hit by the missile?
Why or why not?
f(x)=-2x^2+72x
Answer:
The plane will be fine.
Step-by-step explanation:
[tex]f(x) =-2x^{2}+72x\\650=-2x^{2}+72x\\2x^{2}-72x+650=0\\[/tex]

What is the measurement of angle 1 plz help me !
Answer:
ANGLE 1 = 40°
Step-by-step explanation:
angle 1 = angle 2 ------(alternate interior angles)
2x + 20 = 3x + 10
20 - 10 = 3x - 2x
x = 10.
Angle 1 = 2x + 20 = 2(10) + 20 = 20 + 20 = 40°.

What distance would you travel in 2.5 hours if you are biking with the speed of 6.3 mph?
Answer:
15.75 milesStep-by-step explanation:
Step one:
given
time= 2.5 hours
speed= 6.3mph
Step two:
Required
Distance
we are given the speed in miles per hour, hence the distance will be in miles
we also know that the expression relating speed, distance and time is given as
speed= distance/time
thus
distance= speed*time
distance= 6.3*2.5
distance= 15.75 miles
By using expression for the speed, distance traveled by me in 2.5 hours will be
Given in the question,
Speed = 6.3 mphTime for travelling = 2.4 hoursExpression for the speed of an object is given by,
Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
Therefore, Distance = Speed × Time
By substituting the values of speed and the time in the expression,
Distance traveled = 6.3 × 2.5
= 15.75 miles
Therefore, distance traveled by me in 2.5 hours will be 15.75 miles.

Answer:b
Step-by-step explanation:
A bowling ball is dropped from a height of 50 feet
a. Write a function that gives the height h (in feet) of the bowling ball after t seconds.
h(t)=
b. Find the height of the bowling ball after 1 second.
c. How long does the bowling ball take to hit the ground? Round your answer to the nearest hundredth of a second.
Answer:
A. The function that gives the height of the bowling ball after t seconds is [tex]h(t) = 50-16.087\cdot t^{2}\,\,\,[ft][/tex].
B. The height of the bowling ball after 1 second is 33.913 feet.
C. The bowling ball will take approximately 1.763 seconds to hit the ground.
Step-by-step explanation:
A. From Physics we notice that ball experiments a free-fall, which is an uniform accelerated motion due to gravity and where air friction and effects of the Earth's rotation are neglected. The height of the ball is described by the following kinematic equation:
[tex]h(t) = h_{o}+v_{o}\cdot t +\frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)
Where:
[tex]h_{o}[/tex] - Initial height of the ball, measured in feet.
[tex]v_{o}[/tex] - Initial velocity of the ball, measured in feet per second.
[tex]t[/tex] - Time, measured in seconds.
[tex]g[/tex] - Gravitational acceleration, measured in feet per square second.
If we know that [tex]h_{o} = 50\,ft[/tex], [tex]v_{o} = 0\,\frac{ft}{s}[/tex] and [tex]g = -32.174\,\frac{ft}{s^{2}}[/tex], then the function that gives the height of the bowling ball after t seconds is:
[tex]h(t) = 50-16.087\cdot t^{2}\,\,\,[ft][/tex] (2)
The function that gives the height of the bowling ball after t seconds is [tex]h(t) = 50-16.087\cdot t^{2}\,\,\,[ft][/tex].
B. If we know that [tex]t = 1\,s[/tex], then the height of the bowling ball is:
[tex]h(1) = 50-16.087\cdot (1)^{2}[/tex]
[tex]h(1) = 33.913\,ft[/tex]
The height of the bowling ball after 1 second is 33.913 feet.
C. The bowling ball hits the ground when height is zero. Let equalize (1) to zero and solve the resulting expression:
[tex]50-16.087\cdot t^{2} = 0[/tex]
[tex]16.087\cdot t^{2} = 50[/tex]
[tex]t \approx 1.763\,s[/tex]
The bowling ball will take approximately 1.763 seconds to hit the ground.

Answer: 25percent
Step-by-step explanation: Divide 12 by 3 and you'll get 4.
That means 1/4 or a quarter of the 12 is 3.
(Convert the fraction to its percentage form)
1/4 or 1 divided by 4 equals 0.25

Slope = 2/7; y intercept = 0 and they want me to write it in slope intercept form
Hello again! To do this you must remember that slope intercept form is y=mx+b. m equals slope while b equals y intercept. Our slope is 2/7 while our y intercept is zero. Now, plug them in and you should get the equation y=2/7x+0. We have a zero at the end so we remove the + and zero and get y=2/7x.
Hope it helps! If you need help in the future be sure to reach out to me!
