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

y = 4x - 10
y = 4x + 10
y = 40x
y = 4x + 10x
Answer:
b
Step-by-step explanation:
The required expression for Charles is y = 4x + 10. Option b is correct.
An expression to be determine that explain charles charge for the families have more than 3 children.
Equation are the coded expression that describes the mathematical familiarities of the word statement.
Here, Charles charge $10 more beside of $4 an hour to baby sit for the families having more than 3 children.
⇒ let 'y' is the total charge applied and 'x' is hours of baby sit.
⇒ y = 4x + 10
Thus, the required expression for Charles is y = 4x + 10.

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

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.

Line FG goes through the points (4,9) and (1,3). Which equation represents a line that is perpendicular to FG and passes through the point (2,0)?
-2x+ y=-4
-2x+y=2
X+2y=2
X+2y=4
Answer:
[tex]x + 2y= 2[/tex]
Step-by-step explanation:
Given
Points:
[tex]F = (4,9)[/tex]
[tex]G = (1,3)[/tex]
Required
Determine the equation of line that is perpendicular to the given points and that pass through [tex](2,0)[/tex]
First, we need to determine the slope, m of FG
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex]F = (4,9)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]G = (1,3)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]m = \frac{3 - 9}{1 - 4}[/tex]
[tex]m = \frac{- 6}{- 3}[/tex]
[tex]m =2[/tex]
The question says the line is perpendicular to FG.
Next, we determine the slope (m2) of the perpendicular line using:
[tex]m_2 = -\frac{1}{m}[/tex]
[tex]m_2 = -\frac{1}{2}[/tex]
The equation of the line is then calculated as:
[tex]y - y_1 = m_2(x - x_1)[/tex]
Where
[tex]m_2 = -\frac{1}{2}[/tex]
[tex](x_1,y_1) = (2,0)[/tex]
[tex]y - 0 = -\frac{1}{2}(x - 2)[/tex]
[tex]y = -\frac{1}{2}(x - 2)[/tex]
[tex]y = -\frac{1}{2}x + 1[/tex]
Multiply through by 2
[tex]2y = -x + 2[/tex]
Add x to both sides
[tex]x + 2y= -x +x+ 2[/tex]
[tex]x + 2y= 2[/tex]
Hence, the line of the equation is [tex]x + 2y= 2[/tex]

slope of 3?
F. y = 3x - 2
G. y = 3x + 10
H. y = 3x - 10
I. y = 3x +2
Answer:
y=3x+10
Step-by-step explanation:
First, put the equation into point-slope form.
y-y1=m(x-x1)
y-4=3(x+2)
Next, distribute 3 to (x+2) and simplify.
y-4=3x+6
y=3x+10
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:
Weak Positive Correlation
Step-by-step explanation: I think that’s correct not 100 percent sure
The strength of the linear association between the height and the length of these rectangles is option A. Weak negative correlation.
What is a Weak negative correlation?In this, the both variables should be response to one another here the relationship is not so strong.
So the correlation coefficient for the data that represent the linear relationship between the height and length should be weak
hence, the option a is correct.

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.
