Answers

Answer:

3.75

Step-by-step explanation:

Angle 2 and angle 3 are supplementary angles, so we can add them together and put it equal to 180°

Equation:

30x + 14 + 10x + 16 = 180

Combine like terms:

40x + 30 = 180

Subtract 30 from both sides:

40x = 150

Divide both sides by 40:

3.75

Check:

Take the orginal equation:

30x + 14 + 10x + 16 = 180

Plug in for x:

30(3.75) + 14 + 10(3.75) + 16 = 180

Solve:

112.5 + 14 + 37.5 + 16 = 180

180 = 180 ✅

48 units squared

Step-by-step explanation:

You can find the number of squares in each sector by multiplying by the width and height.

So we have 4 boxes that have 10 squares each giving us 40 squares for the 4 boxes plus the other 2 boxes that have 4 squares each.

4 * 10 + 2 * 4 = 48

We get 48 inches squared.

Answer:

6^6 = 6^2 x 6^4 = 46656

Step-by-step explanation:

6^16/6^2 = 78364164096 so doesn't equal 6^6

(6^2)^8 / 6^4 = 1679616 so doesn't equal 6^6

(6^4)^2 = 1679616 so doesn't equal 6^6

6^-1 x 6^9 = 1679616 so doesn't equal 6^6

6^-1 x 6^-8 = 9.92 so doesn't equal 6^6

Round up or down 70 if rounding to the nearest 10

Answers

your answer is going to be 100 and how you do that is you're going to estimate which means you're taking an educated guess and is it 70 closer to zero or 100 70 is only 20 numbers away and how you find that is by subtracting 100 from 70 which equals 20 and how you do that to see if it's up or down is 50 is in your middle okay so it's going to go from 0 to 50 to 100 on a number line 70 is in between 50 and 100 so that means that you'll be going up now if you did 30 instead of 70 in your equation rounding by 10 then it would be in between the zero and the 50 which that means that you're going down

4x - 2*0 = 104x = 10x = 2.5

The y- intercept is the value of y, when x = 0:

4*0 - 2y = 10- 2y = 10y = - 5

y- -5 = 1/4(x - -7)

y+5 = 1/4(x+7)

(b) Algebraically manipulate your answer in part a to produce the slope– intercept form of the function that has a slope of 3 - 5 and passes through the point (6,1).

Answers

The question illustrates linear equation

The equation in point slope form is: [tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]The equation in slope intercept form is: [tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]

The given parameters are:

[tex]\mathbf{m = \frac 35}[/tex] --- the slope

[tex]\mathbf{(x_1,y_1) = (6,1)}[/tex] -- the point it passes through

(a) The equation in point slope form

This is represented as:

[tex]\mathbf{ y - y_1 = m(x - x_1)}[/tex]

Substitute known values

[tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]

So, the equation in point slope form is: [tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]

(a) The equation in slope intercept form

In (a), we have:

[tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]

Open brackets

[tex]\mathbf{ y - 1 = \frac 35x - \frac{18}5}[/tex]

Add 1 to both sides

[tex]\mathbf{ y = \frac 35x - \frac{18}5 + 1}[/tex]

Take LCM

[tex]\mathbf{ y = \frac 35x + \frac{-18 + 5}5}[/tex]

[tex]\mathbf{ y = \frac 35x + \frac{-13}5}[/tex]

[tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]

Hence, the equation in slope intercept form is: [tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]
