Answer:

y=[tex]\frac{-1}{2}[/tex]x+1

Step-by-step explanation:

First, let's do the easiest part, finding the y-intercept, which shows up at the end of your slope intercept equation, y=mx+b, where slope is rise over run!

- Simply look for where the coordinate is on the y-intercept, which is at y = 1!

Then, we need to find our rise over run, which is basically counting from point a to point b. To get to the lower coordinate from the top, we go down two (-2), and over 4. Which means we "rose" -2, and "ran" 4! It's -2 because we went DOWN, and positive 4 because we went FORWARD. This gave us 2 over 4, which is the same as 1 over 2!

Answer:

y=-1/3x +29/3

Step-by-step explanation

We know that the line perpendicular to a slope of 3 is it's opposite reciprocal. So the slope is -1/3. Substitute -5 as X and 8 as Y so you get:

8= -5/3x +b.

B= 29/3

That's your answer.

Answer:

5 3/8

Step-by-step explanation:

3 1/8 ÷(x−4 7/28 )= 17/18 +1 5/6

Get a common denominator for the right side

3 1/8 ÷(x−4 7/28 )= 17/18 +1 15/18

Combine like terms

3 1/8 ÷(x−4 7/28 )= 1 32/18

3 1/8 ÷(x−4 7/28 )= 2 14/18

3 1/8 ÷(x−4 7/28 )= 2 7/9

We have a ÷ b = c

Rewriting as a ÷c = b

3 1/8 ÷ 2 7/9 = (x−4 7/28 )

Changing from mixed numbers to improper fractions

25/8 ÷ 25 /9 = (x−4 7/28 )

Copy dot flip

25/8 * 9/25 = (x−4 7/28 )

9/8 = (x−4 7/28 )

Add 4 7/28 to each side

9/8  + 4 7/28 = (x−4 7/28 )+ 4 7/28

Simplifying the fractions

9/8 + 4 1/4 = x

Getting a common denominator

9/8 + 4 2/8 =x

4 11/8 =x

4 + 8/8+3/8 =x

90 <------ ANSWER

Answer:

∠ GHI = 40°

Step-by-step explanation:

The inscribed angle GHI is half the measure of the intercepted arc GI, thus

∠ GHI = 0.5 × 80° = 40°

The measure of the ∠GHI is 40°.

An inscribed angle is the angle that an arc at any point on the circle subtends.

From the Inscribed angle theorem:

A circle's inscribed angle is half of the central angle that subtends the same arc on the circle, according to the inscribed angle theorem.

That means,

The measure of the ∠GHI

= the measure of the arc GI /2

= 80°/2

The measure of the ∠GHI = 40°

Therefore, the measure of center angle is 40°.

Answer:

The Flower Garden is not in the shape of a right Δ

Step-by-step explanation:

~ To prove that this garden is in the shape of a right triangle, it can be done so through contradiction ~

Pythagorean Theorem is applied to a right triangle, so we can say that the two legs are 10 and 7 feet, the hypotenuse being 13, knowing it is the longest side;

a^2 + b^2 = c^2,

10^2 + 7^2 = 13^2,

100 + 49 = 169,

149 ≠ 169,

So the Flower Garden will not be in the shape of a right Δ

Answer:

108

Step-by-step explanation:

8^4 = 4096

6^3 = 216

16^-2 = 0.00390625

4096x216x0.00390625 = 3456

3456/32 = 108

Answer:

(3/2)^3

Step-by-step explanation:

The trick here is to identify the common base (it is 2) and express all factors except for 3^2 as powers of 2 that can be added or subtracted.

Note that 8 = 2^3, 6 = 2 * 3, 16 = 2^4 and 32 = 2^5.  Using this info, we can immediately begin reducing the given expression:

                                         (2^3)(2^3)(3^3)        2^6*3^3             3^3

(8^4)(6^3)(16^-2)÷32  =>  ----------------------- = ----------------  =  --------------

                                          2^4*2^5                 2^9                   2^3                                      

                                                                                               = (3/2)^3

Answer: The equation is (3x) + (2x + 20) + (x+10) = 180, and the x = 25.

Step-by-step explanation:

First, you know that all the measures of angles equal 180°.

So, we can make this equation:

(3x) + (2x + 20) + (x+ 10) = 180

Then, solve for x:

3x + 2x + 20 + x + 10 = 180

Combine the like terms that have the variable, x, in them:

6x + 20 + 10 = 180

Now combine the constant numbers:

6x + 30 = 180

Next, subtract 30 from that side:

6x = 180 - 30

6x = 150

Then, divide:

[tex]\frac{6x}{6}[/tex]= [tex]\frac{150}{6}[/tex]

x = 25

Therefore, the equation is (3x) + (2x + 20) + (x +10) = 180, and the x is 25.

Hope this helps! :)

When driving a car with Anti-lock Brakes (ABS), if your brakes fail when you are trying to stop. You should, Push on your brake pedal and hold it down. Shift to a lower gear and slowly apply your parking brake.

An anti-lock braking system (ABS) is a safety anti-skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle.
