Answer:

6

Step-by-step explanation:

7=42 is 7*6

6=30 is 6*5

5=20 is 5*4; it's multiplied by the number below it, so 3 will be 3*2

3 = 6

Step-by-step explanation:

Given: 7 = 42, 6 = 30, 5 = 20

7 <em>(</em><em>x </em><em>6</em><em>)</em> = 42

6 <em>(</em><em>x </em><em>5</em><em>)</em> = 30

5 <em>(</em><em>x </em><em>4</em><em>)</em> = 20

Follow the pattern

4 <em>(</em><em>x </em><em>3</em><em>)</em> = 12

3 <em>(</em><em>x </em><em>2</em><em>)</em> = 6

3 = 6

How do I rotate a point by 180 degrees clockwise?
gizmo_the_mogwai [7]

180 degrees is half of a circle, and clockwise means turning in the direction a clock does - right.

So a point would be turned right halfway around.

If x-y =8 find the value of y when x=3
DedPeter [7]
Answer: y = -5

Substitute in 3 for x.
x - y = 8                            Substitution
3 - y = 8                            Subtract 3 from both sides
-y = 5                                Divide by -1 to both sides
y = -5                                Answer!

You can also check your work.
x - y = 8       
3 - (-5) = 8                  
3 + 5 = 8                        
8 = 8

Work out the equation of the line which has a gradient of 2 and passes through the point (1, 4)
leva [86]

Answer:

y = 2x + 2

Step-by-step explanation:

The slope is also called the gradient of the line.

The slope that is given is two, and the point is (1, 4).

I made a point slope equation, and then converted it into a slope-intercept equation.

y-4=2(x-1)\\\\y-4=2x-2\\\\y-4+4=2x-2+4\\\\\boxed{y=2x+2}

Hope this helps.
