Find the equation of the line that passes through the points (3,-2) and (-1,6) Explain

1 answer:

6 0

Equation: y = -2x + 4

Explanation: The reason that this would be the answer is because when the 2 points shown are put into graph form (as seen in the picture below) we can see that the slope of the equation is -2 and the y-intercept is 4. So, knowing this, we could fill in our slope-intercept form (y = mx + b) and there we have our equation.

That's the wrong right triangle to draw. Reading the problem carefully we want this one, figure attached.

So we have the usual 30/60/90 triangle but not to scale. The sides come in ratio 1:√3:2=x:100:hypotenuse. So

x = 100/√3 ≈ 57.735

We add that to our 133.2 for the total height of the Cyclone, 190.935.

Answer: 190.9

12, 21, 30 and 39 are the first four terms in a sequence

vivado [14]

Answer:

12, 21, 30, 39, 48, 57, 66, 75, 84.

Ninth term is 84.

Step-by-step explanation:

The rule for this sequence is "add 9".

So, using this rule, we can do......

12, 21, 30, 39, 48, 57, 66, 75, 84.

<em>Remember to add 9 each time!</em>

Best of luck :3

A solution to the inequality 3.75 – 3x ≤ 6.

LenKa [72]

Answer:

x ≥ -0.75

Step-by-step explanation:

3.75 - 3x ≤ 6

Subtract 3.75 on both sides.

- 3x ≤ 6 - 3.75

- 3x ≤ 2.25

Divide both sides with -3.

x ≥ 2.25/-3

x ≥ -0.75

Hamish and hairy work as plumbers. Harry earns a dollar more than 5/4 The amount Hamish orange per hour. The amount Harry earns

Mnenie [13.5K]

Answer:

Harry earns 26 and Hamish earns 20

Step-by-step explanation:

The computation of the amount earned by each one of them is shown below:

Let us assume the hairy be Y

And, the Hamish be M

It is given that Harry earns a dollar i.e more than 5/4

And, it is $2 less than 7/5

So, the equation would be

y = 1.25m + 1 ...........................(i)

And,

y= 1.4m -2 .............................(ii)

Now equal both the equations

1.25m + 1 = 1.4m - 2

3 = 0.15m

So, m = 20

Now put the values of m in any of the above equation to find out the value of Y

Y = 1.25m + 1

= 1.25 (20) + 1

= 26
