$840 - 20% = $672 so $672/6 = $112, therefore the answer is $112.

Which two points are on the graph of M(a) = - 3/4a-12?

sertanlavr [38]

Answer:

(-16, 0) and (0,-12) are exactly two points on the graph of the given equation.

Step-by-step explanation:

Here, the given expression is : $M(a) = -\frac{3}{4} a-12$

Here, let M(a) = b

⇒The equation becomes $b = -\frac{3}{4} a-12$

Now, check for all the given points for (a,b)

<u>1) FOR (-9,0)</u>

$RHS is -\frac{3}{4} (-9)-12 = -5.25 \neq 0$

Hence, (-9,0) is NOT on the graph.

<u>2) FOR (-16,0)</u>

Here, LHS = b = 0

and $RHS = -\frac{3}{4} (-16)-12 = 12-12 = 0$

Hence, LHS = RHS = 0 So, (-16,0) is on the graph.

<u>3) FOR (0,12)</u>

Here, LHS = b = 12

$RHS is -\frac{3}{4} (0)-12 = -12 \neq 12$

Hence, (0,12) is NOT on the graph.

<u>4) FOR (0,-12)</u>

Here, LHS = b = -12

$RHS is -\frac{3}{4} (0)-12 = -12$

and LHS = RHS = -12

Hence, (0,-12) is on the graph.

Hence, (-16, 0) and (0,-12) are exactly two points on the graph of the given equation.

Use the formula to evaluate the series -3 + 6 - 12 +24 - ...-az.

aleksklad [387]

Answer:

Your sum = $(-2)^{z}$ - 1

S = ( (-2)^n - 1), If you let n = z, then S = (-2)^z - 1

Step-by-step explanation:

I can use a formula to find the sum of the first n terms.

we have -3, 6, -12, 24, ... etc.

common ratio = r = -2

first term = -3

a_1 = -3

Then: a_n = a_1 * r ^(n -1)

a_n = (-3) * (-2)^(n - 1) is the general formula for the nth term

Sum of first n terms = S = a_1 * (r^n - 1) / (r - 1)

so...

S = (-3) * ((-2)^n - 1 )/ (-2 - 1)

which simplifies to

S = (-3) *((-2)^n - 1) / (-3)

S = ( (-2)^n - 1)

If you let n = z, then S = (-2)^z - 1
