It'll have an open circle on both 7 and 21, with a line connecting.

Which is none of the options, unless one isn't shown?

Step-by-step explanation:

-23 > -4x + 5 > -79

So:

-23 > -4x + 5

-23 - 5 > -4x

-4x < -28

x > -28 / -4

x > 7

-4x + 5 > -79

-4x > - 79 - 5

-4x > -84

x < -84 / -4

x < 21

apply the distributive property to factor out the greatest common factor

9-12x+6y

Answers

If you decompose 9 you will get 3*3 so 9=3*3
If you decompose 12 you will get 2*6,then you can decompose 6 which 2*3 so 12=2*2*3
If you decompose 6 you will get 2*3 so 6=2*3
What do all of these numbers have in common?The 3.
So 3 is the greatest common factor.Now you just put the 3 in front and then open the bracket and divide each of the number by 3.
9/3=3
-12x/3=4x
6y/3=2y
So,this will be your answer 3(3-4x+2y)

Multiplying by which number is equivalent to an increase 49.5%

Answers

Answer:

22.46

Step-by-step explanation:

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

49.5% = 49.5/100 = 49.5 ÷ 100 = 0.495.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 49.5% of its value.

Percentage increase = 49.5% × 22.46

New value = 22.46 + Percentage increase

22.46 equivalent an increase 49.5%

The students in Mr. Nolan's class are writing expressions for the perimeter of a rectangle of side length & and width w.
After they share their answers, the following expressions are on the board:
Sam: 2(l+ w)

Kiyo: 2l+ w
Erica: 2w + 2l

Which of the expressions are correct and how might the students have been thinking about finding the
perimeter of the rectangle?

Answers

Sam and Erica are correct because if you multiply you l and w by two you would get the perimeter and also you can do the value of one w and multiply it by two and also the L hope it helps

The line l is tangent to the circle with equation x^2 + y^2=10 at the point P.
Determine the equation of line l.

Answers

Given:

The equation of a circle is

[tex]x^2+y^2=10[/tex]

A tangent line l to the circle touches the circle at point P(1,3).

To find:

The equation of the line l.

Solution:

Slope formula: If a line passes through two points, then the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Endpoints of the radius are O(0,0) and P(1,3). So, the slope of radius is

[tex]m_1=\dfrac{3-0}{1-0}[/tex]

[tex]m_1=\dfrac{3}{1}[/tex]

[tex]m=3[/tex]

We know that the radius of a circle is always perpendicular to the tangent at the point of tangency.

Product of slopes of two perpendicular lines is always -1.

Let the slope of tangent line l is m. Then, the product of slopes of line l and radius is -1.

[tex]m\times m_1=-1[/tex]

[tex]m\times 3=-1[/tex]

[tex]m=-\dfrac{1}{3}[/tex]

The slope of line l is [tex]-\dfrac{1}{3}[/tex] and it passs through the point P(1,3). So, the equation of line l is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-3=-\dfrac{1}{3}(x-1)[/tex]

[tex]y-3=-\dfrac{1}{3}(x)+\dfrac{1}{3}[/tex]

Adding 3 on both sides, we get

[tex]y=-\dfrac{1}{3}x+\dfrac{1}{3}+3[/tex]

[tex]y=-\dfrac{1}{3}x+\dfrac{1+9}{3}[/tex]

[tex]y=-\dfrac{1}{3}x+\dfrac{10}{3}[/tex]

Therefore, the equation of line l is [tex]y=-\dfrac{1}{3}x+\dfrac{10}{3}[/tex].

Slope intercept is really easy. m is the slope. All you have to do is find 2 points and use rise/run. Rise is how many up or downs (numerator). Run is left or right (denominator). We are given 2 points in the graph. So I counted, 2 down, 12 left. So 2/12. Now remember if the line is going down from left to right, it’s a negative slope. So -2/12. To find the y intercept, just find where the line meets at the y intercept, here it’s -8. So y=-2/12x-8. y=-1/6x-8

Find the value of x°

80 + 25 + x = 180
105 + x = 180
x = 180 - 105
x = 75

What is 20% of 50 and what would 10% equal

20/100 x 50 is 10

10% would be 10/100 is fraction form

I want to help you on the first thing you said,

so always consider a percent as a fraction but there denominator is ALWAYS 100 (a way to remember that is that the word "cent" means 100). The word "of" means multiplication so that means your multiplying it with 50 and just do the multiplication.
