Answer:
w ≤ 19
Step-by-step explanation:
4w−16≤60
Add 16 to both sides.
4w−16+16≤60+16
4w≤76
Divide both sides by 4.
4w/4 ≤ 76/4
w≤19
Step-by-step explanation:
7 = √49
8 = √64
So any positive integer between 50 to 63, both inclusive, have a square root between 7 and 8.
In order to find zeroes of a function, we will probably want to use our quadratic formula.
-b±√b^2-4(a)(c)/2a
If we know our values, we can plug it in.
Our values:
A=1 (Since there is no number in front of x, it is an assumed 1)
B=17
C=72
Now, We can plug it into our formula.
BE SURE TO PUT PARENTHESIS AROUND ALL TERMS!
-(17)±√(17)^2-4(1)(72)/2(1)
Now we can type it into a calculator!
When we plug it into the formula. It gives us two real solutions (or zeroes) which are represented as:
-8 & -9.
Answer:
x = 9
Step-by-step explanation:
y = 2/3x - 6
If the y point is 0, then plug that number into the equation and solve for x.
0 = 2/3x - 6
Add 6 to both sides of the equation.
6 + 0 = 2/3x - 6 + 6 or 6 = 2/3x
Multiply both sides by 3.
3 x 6 = 2/3x x 3 or 18 = 2x
Divide both sides by 2
18/2 = 2x / 2 or 9 = x
Answer:
The answer is B - 288
To get this answer all you need to do is
First, subtract 316 - 28 to get your answer :)
