Answer:
x = 4.
Step-by-step explanation:
We see that it passes through the x axis at the point (4, 0) so x = 4 is a solution.
Check by solving the equation
x^2 - 4x + 13 = 13
Subtract 13 from both sides:
x^2 - 4x = 0
x(x - 4) = 0
x = 0 or x - 4 = 0, so:
x = 0 or 4.
In the first function, it shifts over to the right by 4 units. Then the second function shifts 7 units to the left.
Answer: There will be two different ways of doing so.
Step-by-step explanation:
Since we have given that
Total number of rocks =38
If we want to groups of 10 rocks or as single rocks then there are 2 different ways ;
<u>Case I:</u>
if we group into 10 rocks
there will be four sets in which Ist set contains 10 rocks
Second set contains 10 rocks
Third set contains 10 rocks
and Fourth set remains with 8 rocks only.
<u>Case II:</u>
if we group as single rocks .
There will be 38 sets .
Answer: See explanation
Step-by-step explanation:
Michael is X years old.
Jenny is twice as old as Michael. Thus means that Jenny = 2 × x = 2x
The sum of their ages is 57.
Therefore, x + 2x = 57
3x = 57
x = 57/3 = 19
Michael is 19 years
Jenny's age = 2x = 2 × 19 = 38 years
7.25+3.75=11 pounds total
11/1.5= 7 plus .5 pounds left
So the greatest number they can make is 7
