STEP 1:
identify variables and equations
x= larger number
y= smaller number
FIRST EQUATION
x + y= 42
SECOND EQUATION
y= 2x - 63
STEP 2:
substitute the y value in second equation in for y in first equation
x + y= 42
substitute y value from 2nd equation
x + (2x - 63)= 42
combine like terms
3x - 63= 42
add 63 to both sides
3x= 105
divide both sides by 3
x= 35 larger number
STEP 3:
find y value; substitute step 2 x value into either original equation
x + y= 42
35 + y= 42
subtract 35 from both sides
y= 7 smaller number
ANSWER: larger number is x= 35; smaller number is y= 7.
Hope this helps! :)
For a function: y = 5^x
range is ( 0 , + ∞ )
And we have: y = 5^x + 2 , which is translated 2 units up.
So the range is ( 2, + ∞ ) or ( 2, infinity ).
Answer:
D ) y = 5^x + 2
8.49 \2 = 4.245
So your answer would be 4.245
Answer:
2.75
Step-by-step explanation:
Many square roots, cube roots, etc are also irrational numbers. Examples:
√3 = 1.7320508075688772935274463415059 (etc)
√99 = 9.9498743710661995473447982100121 (etc)
Write an equation. To do this, make one integer equal to x, and the other equal to x+1. Set these equal to 149. Your equation should read x+(x+1)=149. Solve. To do this, add the two x's together. Your equation is now 2x+1=149. Get your x's alone. First, subtract 1 from both sides. Now the equation is 148=2x. Divide both sides by 2 to get x alone. You now have x=74. Plug this value back into the original equation to find your value for the other integer, and you have the two integers as 74 and 75. Hope this helps!
