For what value of q is in the question -13(q+4)=7q+16​
Rufina [12.5K]

Answer:

q=-3 2/5

Step-by-step explanation:

First multiply -13 with (q+4)

-13q-52=7q+16

Now you have to change the order before = the numbers with q and after = the numbers without anything

-13q-7q=52+16

Remember that when you change positions the symbol too

Then solve it

-20q=68

Now u have to divide as i do

q=68/-20

you can simplify it

q=3 8/-20

Now divide by the greater divisor in this case is 4

q=3 2/-5

And organize it

q=-3 2/5

Never forget to do q=(answer)

Hopefully it helps.

Suppose that events a and b are mutually exclusive with p(a) = ½ and p(b) = ⅓.
irina1246 [14]
No, a & b are not independent if they're mutually exclusive.

Mutually exclusive means the two events cannot occur simultaneously. So if "a" happens "b" cannot. In contrast, two events are independent if the occurrence of one has no effect on the occurrence of the other.

Write the quadratic function f(x) = (3-x)2 in standard form.
Nitella [24]

Answer:

y =  - 2x + 6

Step-by-step explanation:

since \: f(x) = y \\

then the equation reads:

y = (3 - x)2 \\ y = 6 - 2x \\

The standard form of an quadratic function is:

y = mx + c \\

So the answer is:

y = mx + c \\ y =  - 2x + 6
