The variables y and x have a proportional relationship, and y = 9 when x = 2.
What is the value of y when x = 10?

Answer:

1,2,3,4,5,6,9,10,12,15,18,20,30,45,60,90,180

Answer:

(3.5,3.5) are the coordinates of X

Answer:

(-3.5, -3)

Step-by-step explanation:

To get to point X, you have to travel -3.5 on the X-axis and -3 on the Y-axis. That means the answer is (-3.5, -3).

Answer:

 [tex]\frac{4x^2y-5xy^2-11}{y}[/tex]  

Step-by-step explanation:

[tex]\frac{8x^2y^2-10xy^3-22y}{2y^2}[/tex]

[tex]=\frac{8x^2y-10xy^2-22y}{2y}[/tex]

[tex]=\frac{4x^2y-5xy^2-11}{y}[/tex]

Answer:

100

Step-by-step explanation:

Write in an equation:

4=4%x, then divide 4% from both sides, and then you get 100.

Answer:

Step-by-step explanation:

We have, 4% × x = 4

or,

4

100

× x = 4

Multiplying both sides by 100 and dividing both sides by 4,

we have x = 4 ×

100

4

x = 100

If you are using a calculator, simply enter 4×100÷4, which will give you the answer.

Answer:

[tex]y=(x+8)(x+10)=x^2 + 18x + 80[/tex]

[tex]\frac{dy}{dx} = 2x + 18[/tex]

[tex]y=0[/tex] when [tex]x=-8[/tex] and [tex]x=-10[/tex]

so the tangent slopes are [tex]\frac{dy}{dx} = 2[/tex] and -2 at those x.

The lines are y = 2x + b and y = -2x + c.

We need to find b and c.

The first line must go through (-8,0) and the second one through (-10,0).

For the first line: 0 = 2*(-8) + b and b = 16.

For the second line: 0 = -2*(-10) + c and c = -20.

Answer: The numbers that would be highlighted are 5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100. They would be highlighted because they are divisible by 5. Only 5 would be a prime number because all the other numbers are divisible by 5 as well so they wouldn't only have 1 and themselves as a divisor.

Answer: x=5

x=−5

Answer:

C- ) 70 degrees

Step-by-step explanation:

180 is the degree of half circle you already have the first number 110 now you need to find out which number gets you to 180 and the only one that works it 70

110+70

=80

Answer: y = 31

Step-by-step explanation:

The equation of a line is y = mx+b

Plugging in the values, we get

y = 4*8 + (-1)

y = 32-1

y = 31

Given Function is

Now , put the value of x = 8 in eqn ( 1 )

Now , put the value of x = 4 in eqn ( 1 )

From eqn ( 2 ) nd eqn ( 3 ) we get,

we know it costs $41 for 9 hours, how much will it be for 1 hour?

[tex]\begin{array}{ccll} \$&hours\\ \cline{1-2} 41&9\\ x&1 \end{array}\implies \cfrac{41}{x}=\cfrac{9}{1}\implies \cfrac{41}{x}=9\implies 41=9x \\\\\\ \cfrac{41}{9}=x\implies 4.56=x[/tex]

Answer:

Keep the exact order that is shown

Step-by-step explanation:

The first exponential already has a point at (1, -2) which means the y-intercept would be less than -2, which is the lowest among the three

The second has a y-int at -2

Third has y-int at 2

Answer:

[tex]\frac{41}{11}.[/tex]

Step-by-step explanation:

1) to make up the equation of the given line:

[tex]\frac{x-X_R}{X_S-X_R} =\frac{y-Y_R}{Y_S-Y_R}; \ => \frac{x+5}{1+5} =\frac{y+6}{5+6}; \ => \frac{x+5}{6} =\frac{y+6}{11}.[/tex]

2) to substitute y=10 into the equation of the given line, then to calculate the value of 'x':

[tex]\frac{x+5}{6} =\frac{10+6}{11}; \ => \ x=\frac{96}{11}-5=\frac{41}{11}.[/tex]

Step-by-step explanation:

You divide the polygon into smaller shapes, rectangles suit this best.

There will be 2 rectangles:

1st rectangle whose length is 24ft and its width is 11 ft (21-10=11).

2nd rectangle its length is 10ft and its width is 7ft.

You find the area of both rectangles. The formula of finding the area of a rectangle is length X width.

1st rectangle has an area of 264 ft² (24 X 11)

2nd rectangle has an area of 70ft² (10 X 7)

Add the area of the two angles to get the area of the polygon.

Answer:

2708

Step-by-step explanation:

If there are 12 times as many students as professors all you have to do is divide the amount of students my 12 (32,500/12)

32,500/12 = 2708.3333 (3 keeps repeating)

Obviously there is not 0.333 repeating professors, cant have 0.3 of a professor so just round down to 2708
