Step-by-step explanation:
Let the larger number be y and the smaller be x.
All you need to do is convert the English statements to mathematical statements.
y = 3x – 1 /the larger of two numbers is 1 less than 3 times the smaller number/
2x + y = 18 + y /if twice the smaller number is increased by the larger number, the result is 18 more than the larger number/
Solve the second equation.
2x + y = 18 + y
2x = 18
x = 9
Then substitute the value of x in the first equation.
y = 3x – 1 = 3(9) – 1 = 27 – 1 = 26
The answer is B. All real values of x such that x >_ 10
Answer:
D 1/16
Step-by-step explanation:
(1/2)^4=.0625
.0625= 1/16
Answer:
First choice.
Step-by-step explanation:
When you solve the system and somehow get both sides two different value. That means both graphs are oarallel (graph of both equations). When two sides are different, we can say that there are no solutions.
Answer:
its (5/2)x
Step-by-step explanation:
(hint: y=mx+b, "m" is the slope)
