Plug y=4 into equaton
8x-4=-12
add 4 to both sides
8x=-8
divide both sides by 8
x=-1

x=-1
y=4
(-1,4)

To solve this, you need to substitute the value of Y into the equation 8X - Y = -12

So, since Y = 4, plug 4 in for Y:

8X - Y = -12
8X - (4) = -12

Now solve for X.

Does that help? Do you have any questions?

Just as a heads up this technique also works for larger equations. If Y = 3X, then you'd just plug 3X in for Y:

8X - Y = -12
8X - (3X) = -12

You got this!

Which expression is equivalent to 2^3/2^-8
Mkey [24]

Answer:

2^{11}

Step-by-step explanation:

<u>Key indices rule: When dividing powers, subtract the indices and keep the base numbers constant.</u>

<u />\frac{2^{3} }{2^{-8} } Based on the rule above, the indices are determined by 3--8, which is 11.

The base number is kept constant.

Therefore, the answer is 2^{11}.

Make x the subject of m=n + x/p
marshall27 [118]

Answer:

\boxed{x = p(m - n)}

Step-by-step explanation:

=  > m = n +  \frac{x}{p}  \\  \\  =  > m = (n \times  \frac{p}{p} ) +  \frac{x}{p}  \\  \\  =  > m =  \frac{pn}{p}  +  \frac{x}{p}  \\  \\  =  > m =  \frac{pn + x}{p}  \\  \\  =  > mp = pn + x \\  \\  =  > x + pn = pm \\  \\  =  > x = pm - pn \\  \\  =  > x = p(m - n)

Anyone know this ?? i need it. PLS SHOW WORK AND I'LL GIVE U BRAINLIEST AND 15 POINTS
olya-2409 [2.1K]

Answer:

60 degrees

Step-by-step explanation:

EF and DC have lines through them indicating that they are equal in length, telling us that the figure is an isosceles trapezoid. Congruent base angles are a property of isosceles trapezoids, like isosceles triangles. This means that the base angles C and F will have the same measure. The measure of angle F is 60 degrees, therefore the measure of angle C will also be 60 degrees.

hope this helps :)
