Answer:
No, A is
Step-by-step explanation:
You can tell by plugging in the numbers. 0 - 3(0) < 1 as 0 < 1.
============================================================
Explanation:
Let's check if choice C is the answer or not
We will plug in x = -2 and y = 1 into the inequality to get
y - 3x < 1
1 - 3(-2) < 1
1 + 6 < 1
7 < 1
That's a false statement since 7 is not smaller than 1. This means the first inequality is false when (x,y) = (-2,1). So we can rule out choice C. Choices B and D are similar stories.
---------------
It turns out that choice A is the answer because
y - 3x < 1
0 - 3(0) < 1
0 - 0 < 1
0 < 1
Which is a true statement. So (x,y) = (0,0) is one solution to this inequality.
I'll let you check the other answer choices. You should find them to be false

The height of a male athlete testing his vertical jump can be modeled by h = − 16t ^2 + 14t. The height is h and the time is t. How many seconds is he in the air?
Answers
Answer:
0.88 (I think this is how Mrs. Futch wants it to be written)
Step-by-step explanation:
h=-16t^2+14t
(Substitute h with 0)
0=-16t^2+14t
(Factor)
0=2t(-8t+7)
2t=0 -8t+7=0

Verizon charges $200 to start up a cell phone plan. then there is a $50 charge each month. what is the total cost for .x months
Answers
Answer:
200 + 50x
Step-by-step explanation:
depending on what x is, you multiply x by 50 and add 200, since 200 is the start up fee and the constant. the 50 dollars per month is a variable, since the more months you own the plan, the more money it would cost.

Write a quadratic function in vertex form whose graph has the vertex ( -5. - 1) and passes through the point (-2.2).
Answers
Answer:
[tex](\frac{1}{3})(x+5)^2-1[/tex]
Step-by-step explanation:
So first let's write a graph in vertex form with a vertex of (-5, -1)
We get
a(x+5)²-1
We now need to determine a
we know that when x= -2 y=2 which means we have
a(-2+5)²-1=2
Solve for a
a(3)²=3
9a=3
a=3/9
a=1/3
Now that we know what a is equal to we can write our equation
[tex](\frac{1}{3})(x+5)^2-1[/tex]
Finding missing angles

Answers
Answer:
65
Step-by-step explanation:
the square means 90 add that to 25 and subtract from 180
Answer:
x = 65
Step-by-step explanation:
The measure of the entire angle is 180°. The angle on the furthest left (with a square in it) is a right angle, meaning that it is 90°.
All three of the angles (90°, x°, 25°) all add up to the measure of the line, which is 180°. So, we can write this equation.
90 + x + 25 = 180
Subtract 90 and 25 from both sides.
90 + x + 25 - 90 - 25 = 180 - 90 - 25
x = 65

A bag contains 40 red and green marbles. The number of green marbles, g, is 9 times the number of red mapples, . How many red marbles are in the bag? O 4 O 6 O 34 O 36
Answers
Answer:
4
Step-by-step explanation:
You need to try out all the numbers.
lets start with 4
if there where 4 red marbles then there would be 9 times as many marbles
so 4 x 9 = 36
Now we add and see if the sum is 40
36 + 4 = 40
We got it on the first try
You can use the same method on more problems like these.

Which of the following equations is equivalent to 3 • 12 = 36?
36 + 3 = 12
36 ÷ 3 = 12
36 • 3 = 12
36 – 3 = 12
Answers
Answer:
B
Step-by-step explanation:
36 ÷ 3 = 12 is basically the division version of the original equation. None of the other equations equal the same answer so B is the correct option.
36 ÷ 3 = 12 is equivalent to 3 • 12 = 36
