A = [tex]\left[\begin{array}{cc}2&-1\\3&1\end{array}\right][/tex] = 2(1) - 3( - 1) =2 + 3 = 5
[tex]A_{x}[/tex] = [tex]\left[\begin{array}{cc}4&-1\\1&1\end{array}\right][/tex] = 4(1) - 1(- 1) = 4 + 1 = 5
[tex]A_{y}[/tex] = [tex]\left[\begin{array}{cc}2&4\\3&1\end{array}\right][/tex] = 2(1) - 4(3) = 2 - 12 = - 10
x = [tex]\frac{A_{x} }{A}[/tex] = 1
y = [tex]\frac{A_{y} }{A}[/tex] = - 2

Use the inequality 24 ≥ 58 + 5(x - 3.8)
Solve for the inequality X.
Pls help I need to hand it in by 4:00..
Answer:
Work shown below!
Step-by-step explanation:
24 ≥ 58 + 5(x - 3.8)
Distribute;
24 ≥ 58 + 5x - 19
Collect like terms;
24 ≥ 39 + 5x
Subtract 39 from both sides;
-15 ≥ 5x
Divide both sides by 5;
x ≥ -3

What is the value of x?
2x+20
3(x-10)
Answer:
x = 50
Step-by-step explanation:
By the definition of vertical angles you can set these two equations equal to each other.
2x+20=3(x-10)
then, just simplify to get the correct answer by using order of operations.
2x+20=3x-30

f(x) = 2x-2+5
Step-by-step explanation:
from,
f (x) = 2x-2+5
BUT x=-2
f (x) = 2 (-2)-2+5
= -4-2+5
= -6+5
= -1
so,
f (x) = -1

Step-by-step explanation:
A die is rolled twice. Find the chance that the ace (single dot) comes up on one of the two rolls, but not both. Record your answer as a percentage rounded to the nearest tenth of a percent.
Answer:
13.9%
Step-by-step explanation:
In order to calculate the probability of this happening, we would need to multiply the probability of one of the rolles being an ace with the probability of one of the roles NOT being an ace. Since the probability of rolling an ace is 1/6 (since there is only one ace in a six-sided die) then the probability of NOT rolling an ace is 5/6
[tex]\frac{1}{6} * \frac{5}{6} = \frac{5}{36}[/tex] or 0.1388 multiply by 100 to get percentage value
0.1388 * 100 = 13.9%
Therefore, the probability of getting one ace and one non-ace roll is 13.9%

Step-by-step explanation:
you cant add 1 to 5x, so subtract 1 on both sides leaving you with 1 + 5x < 4 that equals 5x < 3 -1 -1
then divide 5 from both sides 5x < 3 This leaves 5 5
you with x < 3/5

Answer:
it is A and C
Step-by-step explanation:
If you do the math and equations of all of these, you will find that:
10 is 2.5x bigger than 4 (Side lengths DE and BA)
and if we do the equation:
x · 2.5
(the x variable stands for the different side lengths of triangle ABC)
it will equal the side lengths of the bigger triangle.
and when I finished doing that, I multiplied all of the answers to find the area:
12.5 x 7.5 x 10 which altogether is 937.5
none of the other answers for the total of the triangle add up to be that, but side length EF is 7.5, which I used to get my total answer of 937.5.
So the answer is A and C
