Answer:
4(x^2+23
Step-by-step explanation:
The blue pens would cost $15 and the black ones would cost $25.50. In total that is $40.50.
Answer:
The product is <u>1.4</u>
Step-by-step explanation:
Every time you multiply 0.2 by a number you will add 0.2 to the last number.
0.2 x 1 = 0.2
0.2 x 2 = 0.4
0.2 x 3 = 0.6
0.2 x 4 = 0.8
0.2 x 5 = 1.0
0.2 x 6 = 1.2
0.2 x 7 = 1.4
Hope this helps :)
sorry if im wrong
The general form for a parabolic dish is:
y=x^2/(4f), where f=focus' y coordinate when x=0
So if you are given the equation:
8y=x^2, you need only to rearrange it to the form y=x^2/(4f)
y=x^2/8
Since 8=4f, f=2 inches and the focal point of course (0,2)
Answer:

Step-by-step explanation:

Subtract 7x from both sides to isolate y


Divide both sides by -4 to isolate y

Simplify and flip the
because you are dividing by a negative number

Finito.
