7y=-24
y= -24/7
You have to add the two vaiables and then divide to get the y by itself.
Answer:
D
Step-by-step explanation:
they don't eat the same food, so it rules out the first three sorry if wrong
Answer:
no. see below
Step-by-step explanation:
This much of Josh's working is correct:
x^2-6x=7
x^2-6x+9=7+9
(x-3)^2=16
At this point Josh apparently overlooked the fact that he needed to take the square root of both sides of the equation. Had he done that, he would have ...
x -3 = ±4
x = 3+4 . . . or . . . 3 -4
x = 7 or -1
_____
Josh reported values of x that would match ...
x -3 = ±16
He <em>violated the equal sign</em> by taking the square root on the left, and multiplying by ±1 on the right. Doing different operations on the two sides of the equation will mean the value of x is changed to something other than what you're looking for.
Answer:
The equation of the circle can be written as:
Step-by-step explanation:
The general equation of a circle with center
and radius
is:

In our example, we know
, as we just have to make sure we need determine
.

As the circle passes through (10, 14), that pair of values for x and y must satisfy the equation. So we have:






Thus the equation of the circle can be written as:

Answer:
0.81
Step-by-step explanation:
There are 8 pints = 1 gallon
8 times 2= 16/19.68=0.813
each pint is 0.81 cents
