Step-by-step explanation:
3/5 divided by 1/2 = 6/5 mins us that right
Answer:
$.53 per ball
Step-by-step explanation:
The total cost of the golf balls is $9.54
There were 18 golf balls
The cost per golf ball is cost/ number of balls
9.54/18
.53
$.53 per ball
I think is <span> x = 7 or<span> x = -7
</span></span><span>Equation at the end of step 1 :</span><span> 3x2 - 147 = 0
</span><span>Step 2 :</span><span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
<span> 3x2 - 147</span> = <span> 3 • (x2 - 49)</span>
Trying to factor as a Difference of Squares :
<span> 3.2 </span> Factoring: <span> x2 - 49</span>
Theory : A difference of two perfect squares, <span> A2 - B2 </span>can be factored into <span> (A+B) • (A-B)
</span>Proof :<span> (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 <span>- AB + AB </span>- B2 =
<span> A2 - B2</span>
</span>Note : <span> <span>AB = BA </span></span>is the commutative property of multiplication.
Note : <span> <span>- AB + AB </span></span>equals zero and is therefore eliminated from the expression.
Check : 49 is the square of 7
Check : <span> x2 </span>is the square of <span> x1 </span>
Factorization is : (x + 7) • (x - 7)
<span>Equation at the end of step 3 :</span><span> 3 • (x + 7) • (x - 7) = 0</span>
Domain is: D = all real numbers
and Range is: R = {y | y > 0}
Option C is correct.
Step-by-step explanation:
We are given a function and we need to find domain and range of this function
Domain:
The domain of a function is the set of points for which the function is real and defined.
Since all the values give the result which is real and defined so domain is all real numbers.
Range:
The set of values of the variable that is dependent, the function should be defined.
So, all the values should be greater than 0 i.e {y | y > 0}
So, Domain is: D = all real numbers
and Range is: R = {y | y > 0}
Option C is correct.
