Slope intercept form: y=3/4 - 3

slope:3/4

Y-intercept: -3

Because you subtract 4y from both sides to get it on the other side of the equation. You don’t want it to be 4y=3x-12 though so you would divide both sides by 4 which would give you y=3/4x-3. I hope this is right and it helps

Answer:

2 or -2

Step-by-step explanation:

If x² - 8x = -12

Step 1

We find x by solving

x² - 8x = -12

We equate to zero

x² - 8x + 12 = 0

We factorise

x² - 6x - 2x + 12 = 0

x(x - 6) -2(x - 6) = 0

(x - 6) (x - 2) = 0

x - 6 = 0, x = 6

x - 2 = 0, x = 2

x = 6 or 2

Step 2

What is x - 4?

When x = 6

= 6 - 4 = 2

When x = 2

= 2 - 4 = -2

Therefore, x - 4 = 2 or -2

Is that not right? or am I just wrong cause it says that it is not right please help

RideAnS [48]

Answer:

98 cm²

Step-by-step explanation:

The area of a circle is:

$A=\pi r^2$

A semicircle is half a circle therefore the area of a semicircle would be:

$A=\frac{1}{2}\pi r^2$

We can plug in the given values into the equation:

$A=\frac{1}{2}*3.142*(7.9)^2\\A=\frac{1}{2}*3.142*62.41\\A=\frac{1}{2}*196.09222 \\A=98.04611$

We need to round to TWO sigfigs meaning...

$A=98 \ cm^2$

Sigfig rules:

Nonzero numbers are significant

Trailing zeros are significant (only if there is a decimal point)

Any sandwiched zero is signification (Ex: 405 --> 3 sigfigs)
