Why does the equation 9−2x−9−16x=−14x−7−4x−11 have no solutions?
A) because if you add 18x to both sides of the equation and simplify, you get −18=−18
B) because if you add 18 x to both sides of the equation and simplify, you get 0 = - 18
C) because if you subtract 18x from both sides of the equation and simplify, you get −18=−18
D) because if you subtract 18x from both sides of the equation and simplify, you get 0=−18

Engineers measure angles in gradients, which are smaller than degrees. The table shows the conversion of some angle measures in degrees to angles in gradients. What is the slope of the line representing the conversion of degrees to gradients?
Express your answer as a decimal rounded to the nearest hundredth.
Answer:
1.11
Step-by-step explanation:
The slope of the line representing the conversion of degrees to gradients is 1.11.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that:
Engineers measure angles in gradients, which are smaller than degrees.
The formula for the slope:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Taking two points (-180, -200) and (-90, -100)
[tex]\rm m =\dfrac{-100-(-200)}{-90-(-180)}[/tex]
m = 100/90
m = 1.11
Thus, the slope of the line representing the conversion of degrees to gradients is 1.11.

The graph of a system of linear equations shows 2 lines with different slopes.
Part 1: What type of lines are they?
Part 2: Are the x and y intercepts the same or different?
Part 3: How many solutions would this system of equations have?
Answer:
they show parralel line and perpendicular line
if the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.
the x and y intercept are different
two solutions

Step-by-step explanation:
Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
On any given week, if Salesman B earns $1,020, how many sales did he have for the week?
______ sales
If we take the paycheck amount of $1020 and subtract it by the weekly salary of $300.
$1020 - $300 = $720
We get $720 in sale commissions. So to get the number of sales, you divide the $720 by the $40 per sale commission.
$720/$40 = 18
Therefore, the sales Salesman B has for the week is 18.

I think the answer is
y=-1/3x + 5
Step-by-step explanation:
the formula is y= mx +b
m-represents the slope
b-represents the y-intercept( where the line graphed)
since the line intersects +5 on the y-intercept and the slope is rise 1 over run -3 the answer is y= -1/3x +5

Which gives the correct values for points A, B, C, and D? A number line going from negative 1 to 0. There are 5 equal spaces between the numbers. The line contains negative 1, C, D, A, B, 0. A = negative one-fifth, B = negative two-fifths, C = negative three-fifths, D = negative four-fifths A = negative one-fifth, B = negative two-fifths, C = negative four-fifths, D = negative three-fifths A = negative four-fifths, B = negative three-fifths, C = Negative two-fifths, D = negative one-fifth A = negative two-fifths, B = negative one-fifth, C = negative four-fifths, D = negative three-fifths
Answer:
b
Step-by-step explanation:
The correct values for points A, B, C, and D are negative one-fifth, B = negative two-fifths, C = negative three-fifths, and D = negative four-fifths. Option A is correct.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers. While the number line is the representation of the numbers on a straight line that goes infinitely on both sides.
It is given that, the number line goes from negative 1 to 0. There are 5 equal spaces between the numbers.
It is given that, the number line goes from negative 1 to 0. There are 5 equal spaces between the number
The value of A, B, C, and D on the number line is as,
A= -1/5
B= -2/5
C= -3/5
D= -4/5
E= -5/5 = -1
Thus, the correct values for points A, B, C, and D are negative one-fifth, B = negative two-fifths, C = negative three-fifths, and D = negative four-fifths. Option A is correct.
