Solve the following equation. |x| + 8 = 17 A. x = 9 or x = -9 B. x = 25 or x = -25 C. x = 25 or x = -9 D. x = -25 or x = -9
Answer:
a
Step-by-step explanation:
|x| means absolute value.
17-8=9. the absolute value of 9 is 9. (thats why all the negative answers are wrong)

Tickets for the school play cost $7 each. Each member of the cast gets 1 free ticket for a family member. For the run of the play, 210 tickets are collected, including all the free tickets, and the box office makes $1,358 from ticket sales. The equation that models this situation is7(210 – c) = 1,358 where c is the number of cast members. How many cast members are in the play?
Answer:
there are 16 cast members.
Step-by-step explanation:
7(210-c)=1358 multiply everything in the parentheses by 7
1470-cx=1358
-7c=-112 subtract 1470 from both sides
c=16 divide -112 by -7
c=16

Answer: C) No, because one x-value corresponds to two different y values.
Here we have x = 3 correspond to y = 4 and y = 3 at the same time.
A function is only possible if any x input leads to exactly one y output. Put another way, we can't have x repeating any values if we want a function.
If you plot the points from the table, then you'll see the graph fails the vertical line test and that's a visual way to see we don't have a function.
Answer:
C
Step-by-step explanation:
If one x-value has more than one y-value then it is not a function

Find the measures of the missing angles
Answer:
Step-by-step explanation:
∠1 = 180° - 88° = 92°
∠5 = 81° (alternate interior angles)
∠4 = 180° - ( 81° + 64° ) = 35°
∠3 = 180° - ( 81° + 35° ) = 64°
∠2 = 88° - 64° = 24°
Answer:
1. 92°
2. 24°
3. 64°
4. 35°
5. 81°
Step-by-step explanation:
1.
180 - 88 = 92°
5.
81° and ∠5 are alternate angles because there are two parallel lines. This means that ∠5 would be 88° as well (alternate angles are equal)
4.
Sum of angles in a triangle = 180°
∠4 + 88 + 64 = 180
∠4 = 35°
3.
Linear pair = 180°
∠3 + 81 + 35 = 180
∠3 = 180 - 81 - 35
∠3 = 64°
2.
Sum of angles in a triangle = 180°
∠2 + 92 + 64 = 180°
∠2 = 24°
Working alone, it take jill 8.4 hours to pick forty bushels of apples. Maria can pick the same amount in 15 hours. If they work together how long would it take them
Answer:
answer is 5.4 hours (rounded)
Step-by-step explanation:
8.4 divided by 40 is 4.76
15 divided by 40 is 2.66
add those two up and it'll be 7.42
7.42 divided by 40 is 5.3908
A person standing close to the edge on top of a 144-foot building throws a ball vertically upward. The quadratic function h ( t ) = − 16 t 2 + 128 t + 144 models the ball's height about the ground, h ( t ) , in feet, t seconds after it was thrown. What is the maximum height of the ball?
Answer:
400mStep-by-step explanation:
Given the quadratic equation that models the height of the ball above the ground as;
h ( t ) = − 16 t^2 + 128 t + 144
t is in seconds
To get the maximum height of the ball, first we must know the time taken by the ball to reach the maximum height.
Note that the ball has a velocity of zero at its maximum height.
v(t) = dh/dt
v(t) = -32t+ 128
at max height, v(t) = 0
0 = -32t + 128
32t = 128
t = 128/32
t = 4secs
To get the maximum height of the ball, you will substitute t = 4 into the modeled function as shown;
h ( t ) = − 16 t^2 + 128 t + 144
h ( 4 ) = − 16 (4)^2 + 128 (4) + 144
h ( 4 ) = − 256 + 512 + 144
h(4) = 400m
Hence the maximum height of the ball is 400m

Explain the process you would use to determine what form a solution to a system of inequalities should take. What are some tips and tricks?
Answer:
Solving a system of inequalities is almost like solving a system of equations. Pretend that the inequality signs are equal signs for a moment. Then, solve the system for the two unknown variables just like how you would solve for in a system of equations.
But, there's a catch. If you divide both sides of the inequality by a negative number, you have to flip the inequality sign. For example, if you are trying to solve the inequality -x > 4 you would have to divide both sides of the equation by -1. We would get x < -4 (see how I switched the inequality sign from > to <).
Once you find the values of x and y (they will be an inequality), graph the solutions.

Your cell phone plan costs $34.99 per month plus $0.15 for each text message you send or receive. You have at most $40 to spend on your cell phone bill. what is the maximum number of text messages that you can send or receive next month?
Answer:
33 texts
Step-by-step explanation:
34.99+0.15(t)=40
lets say t is number of texts
subtract 34.99 from both sides
0.15(t)=$5.01
divide 5.01 by .15
33.4
but you cant send .4 of a text
so 33 texts
