I hope you get it right

Answer: y=5/3x-4

Step-by-step explanation:

Hi, you could find the slope with any 2 points on the line. For accuracy, I will choose the points (6, 6) and (0, -4), meaning when x =6, y=6, and when x=0, y=-4. Then you can set up an equation. Because the line on this graph is linear (meaning straight), the form of the equation would be y=ax+b. (If it was a parabola, it would be y=ax^2+bx+c).

y=mx+b (Or some people prefer y=ax+b, but the same thing).

Now, plug in the x and y values, getting:

6 = 6m+b and -4=0*m+b

When you simplify, you will get that b is -4, and then m is 5/3

So the equation is y=5/3x-4

You can plug the numbers of x and y in to check your answer.

Hope this helps!

The scientific notation representation of 23,000 is 2.3 x 10⁴

To express the number 23,000 in scientific notation, we need to move the decimal point to create a number between 1 and 10, and then multiply it by a power of 10.

Starting with 23,000, we can move the decimal point to the left four places to get 2.3. This means we divided the original number by 10,000 (10⁴). To compensate for this division, we multiply 2.3 by 10,000 in the form of 10⁴.

Thus, the scientific notation representation of 23,000 is 2.3 x 10⁴. The coefficient (2.3) is between 1 and 10, and the exponent (4) indicates the number of decimal places the original number was moved.

Answer:

2.06 rad

Step-by-step explanation:

To change degree measure to radian measure

radians = degrees × [tex]\frac{\pi }{180}[/tex] , then

radians = 118 × [tex]\frac{\pi }{180}[/tex]

            = [tex]\frac{118(\pi )}{180}[/tex] ≈ 2.06 rad ( to the nearest hundredth )

Answer:

2.06 radians to nearest hundredth.

Step-by-step explanation:

Radians = degrees * π/180

= 118 * π/180

= 0.6556π

= 2.0596.

Answer:

Anita's monthly bill will be $164.25.

Step-by-step explanation:

Since Anita has a cellphone contract that costs her R100 per month plus 85 cents per peak time SMS, and 25 cents per off-peak time SMS, if she sends 45 SMSs during peak time and 105 SMSs during off-peak time In a month To determine what will her monthly bill come to, the following calculation must be performed:

100 + (0.85 x 45) + (0.25 x 105) = X

100 + 38.25 + 26.25 = X

138.25 + 26.25 = X

164.25 = X

Therefore, her monthly bill will be $ 164.25.

Answer:

...

Step-by-step explanation:

1. B

angle A is 63 since 27+90= 117, 180-117= 63 (since a straight line is 180°)

2. 7x + 10 = 150 (since they are vertical angles)

7x = 140

x = 20

now plug in 7(20) +10

140+10=150

When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same

Step-by-step explanation: A has the greatest rate of change because it moves 5 spaces up and one right while B moves 3 spaces and C moves 4 spaces.

Answer:

C (circumference) =2×π×r

we've got a 30-60-90 triangle

which means 9=d√3, d=5.19 exact inches

or ≈5.20 inches

d=2r, r=5.20÷2≈2.60 inches

C=2×3.14×2.60≈16.328

Answer:

Step-by-step explanation:

take reference angle as A

using sin rule

sin A=opposite/hypotenuse

sin A=5/13

sin A=0.38

A=sin 22.5

A =22.5 degree

Answer:

17.7

Step-by-step explanation:

I'm assuming you meant R(17, -2) to W(-2, 3).  Here the x-coordinate changes by 17 - (-2), or 19, and the y-coordinate by 5.  Think of these as the legs of a right triangle.  The distance between these points is the length of the hypotenuse of this triangle:  d = √(5^2 + 17^2)

or √314, which, to the nearest tenth is 17.7.

Step-by-step explanation:

Answer:

x=2, y = -4.

or as an ordered pair it is (2, -4).

Step-by-step explanation:

-x + 6y = -26

x + 5y =  -18      Add these 2 equations to eliminate x:

0 + 11y = -44

y = -44/11 = -4.

Now substitute y = -4 in the first equation:

-x + 6(-4) = -26

-x - 24 = -26

-x = -26 + 24 = -2

x = 2.

Check the result by substituting in equation 2:

x + 5y = 2 + 5(-4) = 2 - 20 = -18  - checks out.
