Step-by-step explanation:
opening the bracket,the equation therefore is
-8x + 1 > 5 - 3x
add 8x to both sides
- 8x + 8x +1 > 5 - 3x + 8x
1 > 5 + 5x
subtract 5 from both sides
1 - 5 > 5 - 5 + 5x
-4 > 5x
Divide through by 5
-4/5 > x
which is therefore written is
x < -4/5
If triangle ABC has the following angle measurements, find the value of Angle A, Angle B, and Angle C.
∠A=4x − 17
∠B= 3x + 8
∠C= x + 13
Answer:
b
Step-by-step explanation:
Answer:
Step-by-step explanation:
4x - 17 + 3x + 8 + x + 13 = 180
8x + 4 = 180
8x = 176
x = 22
<A = 4x - 17
<A = 4*22 - 17
<A = 88 - 17
<A = 71
============
<B = 3x + 8
<B = 3*22 + 8
<B = 66 + 8
<B = 74
============
<C = x + 13
<C = 22 + 13
<C = 35
A B and C add to 180 as they should.

Alexander is a stockbroker he earns 11% commission each week last week he sold $7000 worth of stocks how much did he make last week in commission if he averages the same amount each week how much did he make in commission in 2011
Answer:
the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively
Step-by-step explanation:
The computation of the amount that he makes last week and in the year 2011 is as follows:
= Sale value of the stocks × earning percentage × number of weeks in a year
= $7,000 × 11% × 52 weeks
= $40,040
hence, the amount that he makes last week and in the year 2011 is $770 and $40,040 respectively
We simply applied the above formula so that the correct value could come

How do I find x in these equations
Answers:
Problem 9) x = 1Problem 10) x = 3Problem 11) x = 12Problem 12) x = 12==============================================
Explanation:
For problems 9 through 12, we'll use the same set of steps. Recall that any parallelogram has the property that the adjacent angles are supplementary. This means close by angles add to 180. Each of the four diagrams show pairs of adjacent angles.
------------------
In problem 9, we have the following steps
(79x-1) + (102) = 180
79x + 101 = 180
79x = 180-101
79x = 79
x = 79/79
x = 1
------------------
Problem 10 is the same idea
(85) + (30x+5) = 180
30x+90 = 180
30x = 180-90
30x = 90
x = 90/30
x = 3
------------------
Problem 11
(55)+(9x+17) = 180
9x+72 = 180
9x = 180-72
9x = 108
x = 108/9
x = 12
------------------
Problem 12
(3x+12)+(132) = 180
3x+144 = 180
3x = 180-144
3x = 36
x = 36/3
x = 12
Answer:
9. X = 1
10. X = 3
11. X = 12
12. X = 12
Step-by-step explanation:
9.
1) 79x - 1 + 102 = 180
2) 79x + 101 = 180
3) Subtract 101 from both sides
4) 79x = 79
5) x = 1
10.
1) 85 + 30x + 5 = 180
2) 30x + 90 = 180
3) Subtract 90 from both sides
4) 30x = 90
5) x = 3
11.
1) 55 + 9x + 17 = 180
2) 9x + 72 = 180
3) Subtract 72 from both sides
3) 9x = 108
4) X = 12
12.
1) 3x + 12 + 132 = 180
2) 3x + 144 = 180
3) Subtract 144 from both sides
4) 3x = 36
5) x = 12
All answers have been checked by plugging the X back into the equation.

Is the relation a function? {(3,4), (5,0), (2,4), (-5,-5)}
Answer:
Yes
Step-by-step explanation:
You are using the x values once, so it will pass the vertical line test.
{(3,4), (5,0), (2,4), (-5,-5)} the relation is a function.
What is a function?A relation is a function if it has only One y-value for each x-value.
The relation is {(3,4), (5,0), (2,4), (-5,-5)}
Relation on a set may, or may not, hold between two given set members.
Three comma four comma five comma zero two comma four comma minus five comma minus five.
{(3,4), (5,0), (2,4), (-5,-5)} the relation is a function, because in (x,y) the x terms are not repeated.
For every y value there is a unique x value.
Hence, {(3,4), (5,0), (2,4), (-5,-5)} the relation is a function.

Which is the BEST estimate of the average rate of change for the function graphed, over the interval 1 sxs 3?
es)
A)
-2
B)
-3
D)
-6
Answer: -3
Step-by-step explanation: just multiply
The best estimate of the average rate of change for the function graphed over the interval 1 ≤ x ≤ 3 is 3.
What is Average Rate of Change of a Function?Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.
The interval given is 1 ≤ x ≤ 3.
The graph of the function is given below.
It can be clearly seen that,
The y value corresponding to x = 1 is y = f(1) = 2.
So one point on the graph is (1, 2).
The y value corresponding to x = 3 is y = f(3) = 8.
So the other point on the graph is (3, 8).
Average rate of change over 1 ≤ x ≤ 3 = [f(3) - f(1)] / [3 - 1]
= [8 - 2] / [2]
= 6/2
= 3
Hence the best estimate for the average rate of change of function over the interval 1 ≤ x ≤ 3 is 3.

Last year 858 people attended the Middleton County Fair. This year 1,635 people attended. What was the percent increase from last year to this year? (Round to the nearest percent)
Answer:
91%
Step-by-step explanation:
The first step is to calculate the increase
= 1635-858
= 777
Therefore the percent increase can be calculated as follows
= 777/858 × 100
= 0.905× 100
= 90.5 %
= 91%
Hence the percentage increase is 91%

Answer:x = -0.1290322581
Step-by-step explanation:
Simplifying
9x + -4(1 + 10x) = 0
9x + (1 * -4 + 10x * -4) = 0
9x + (-4 + -40x) = 0
Reorder the terms:
-4 + 9x + -40x = 0
Combine like terms: 9x + -40x = -31x
-4 + -31x = 0
Solving
-4 + -31x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + -31x = 0 + 4
Combine like terms: -4 + 4 = 0
0 + -31x = 0 + 4
-31x = 0 + 4
Combine like terms: 0 + 4 = 4
-31x = 4
Divide each side by '-31'.
x = -0.1290322581
