Answer:
yes
Step-by-step explanation:
Domain: x is greater than or equal to 2 but is less than our equal to 7
range: y is greater than or equal to 6 but is less than or equal to 18
175 divide by 25 should be 7
then using 80 divide by 40 is 2
7+2=9
then 2 times 40, and 7 times 25, the result is 285
285 divide by 9 get 31.6666......... or 31.7
Answer:
x = 1, y = 10
Step-by-step explanation:
y = -5x + 15 --- Equation 1
2x + y = 12 --- Equation 2
Substitute y = -5x + 15 into Equation 2:
2x + y = 12
2x - 5x + 15 = 12
Evaluate like terms.
15 - 3x = 12
Isolate -3x.
-3x = 12 - 15
Evaluate like terms.
-3x = -3
Find x.
x = -3 ÷ -3
x = 1
Substitute x = 1 into Equation 2:
2x + y = 12
2(1) + y = 12
2 + y = 12
Isolate y.
y = 12 - 2
y = 10
A number is even if it ends with an even digit, so 8 must be the last one.
Now, the digits to the left are more worth than those on the right, so if you want a big number you have to stack the greatest digits to the left, otherwise if you want a small number you have to stack the smallest digits to the left.
So, the greatest number is 7538, the smaller is 3578.
