which of the following shows the solution to the inequality
Answer:
I got x = 1
Step-by-step explanation:
First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:
[tex]1/2(1) -3 \leq -1\\1/2 -3\leq -1\\-2.5\leq -1[/tex]
And since -2.5 is less than -1 this statement is true. x does in fact equal 1

Step-by-step explanation:
Givens
a^2 + b^2 = c^2
a = 4x
b = x + 2
c = 3x + 4
Solution
(4x)^2 + (x + 2)^2 = (3x + 4)^3 Remove all the brackets.
16x^2 + x^2 + 4x + 4 = 9x^2 + 24x + 16 Collect like terms on the left
17x^2 + 4x + 4 = 9x^2 + 24x + 16 Subtract the terms on the right
8x^2 - 20x - 12 = 0
This factors into
(4x - 12)(2x + 1)
There are 2 answers
4x - 12 = 0
4x = 12
x = 12/4
x = 3
or
2x + 1 = 0
2x = - 1
x = - 1/2
You have to look at x = -1/2 carefully. The problem is that 4x = 4*(-1/2) = - 2 which is not possible in Euclidean Geometry.
So the only answer is x = 3

Answer:
gidetgfddtgfft5f5f5f5d5f6guhuhug5xtdrd4s4d5d6v7g7h8n8b7v6v6
Answer:
Let J represent the number of tickets Jose sells. Let M represent the number of tickets Mark sells. Make equations, if Mark sells 15 more tickets than Jose, the equation is J+15=M. Because we know that in between both of them they sell 63 raffle tickets, then M+J=63. Now plug in the value of M (J+15) into M+J=63. And you get (J+15)+J=63, which is 2J+15=63. Subtract 15 from both sides and get 2J=48. Now divide 48 by 2, J=24. So now you know Jose sold 24 tickets, and to find how many Mark sold, plug in 24 into J+15=M and get 24+15=M where M is 39. Now check, 24+39=63. So Mark sold 39 tickets and Jose sold 24.

Each side of a rectangle must be perpendicular to two of its other sides. Is it possible for a rectangle to be formed by the intersections of the lines y=4x−7, y=−14x+2, y=−4x+2, and y=−14x−2? Justify your answer.
A. Yes, one of the lines is perpendicular to two other lines, so a rectangle can be formed
B. Yes, each line is perpendicular to two other lines, so a rectangle can be formed
C. No, one of the lines is not perpendicular to any of the lines, so a rectangle cannot be formed.
D. No, each of the lines is perpendicular to only one other line, so a rectangle cannot be formed.

In Triangle ABC, angle A measures 40 degrees. Give possible angle measures for B and C.
Answer:
B = C = 70°
Step-by-step explanation:
In Triangle ABC, angle A measures 40 degrees.
We need to find the possible angle measures for B and C if ABC is in isosceles triangle.
For an isosceles triangle, two sides of a triangle are equal. We know that if two sides are equal, the corresponding angles are equal. Let equal angles are x. The sum of an isosceles triangle is equal to 180 degrees. So,
40 + x +x = 180
40 + 2 x = 180
2x = 140
x = 70 degrees
So, the possible angle measures for B and C is equal to 70°.

Easton practices the piano the same number of minutes each day. The relationship between the number of days, x, and the total number of minutes he practices, y, is represented by the graph below. A point (8, 200) is labeled below. Which statement about the graph is true?
The true statement about the graph is that it shows a proportional relationship
How to determine the true statement about the graphFrom the question, we have the following parameters that can be used in our computation:
The graph (added as an attachment)
On the graph, we have the following observations and highlights
The graph is represented by a straight lineThe line of the graph passes through the originThe line of the passes through the point (8, 200)Using the above as a guide, we have the following:
A graph that has the above features is not just a linear equation, it is a proportional linear equation
This means that it has a unit rate
And the unit rate is
Unit rate = 200/8
Unit rate = 25
Hence, the graph shows a proportional relationship

Find the LCM of 40a2b and 48ab4.
Answer:
Step-by-step explanation:
40a²b = 2* 2 * 2 * 5 * a² * b = 2³ * 5 * a² * b
48ab⁴ = 2 * 2 * 2 * 2 * 3 * a *b⁴ = 2⁴ * 3 * a * b⁴
LCM = 2⁴ * 3 * 5 * a² * b⁴
= 16 * 3 * 5 * a² * b⁴
= 240a²b⁴
