Answer:
8421
Step-by-step explanation:
8050 < abcd < 8500
We must have a = 8, so the number is 8bcd.
The value of a is 20 times the value of b, or a= 2b.
a = 8, so b = 4.
The value of b is 20 times the value of c, or b = 2c.
b = 4, so c = 2.
The value of c is 20 times the value of d, or c = 2d.
c = 2, so d = 1.
The secret number is 8421.
Answer:
f(-5) = 6
Step-by-step explanation:
f(x) = x + 11
Let x = -5
f(-5) = -5+11
f(-5) = 6
Well, I will not just give you a straight answer, since I do not have the resources to currently do so. But as a tip, I would try the substitution method to get rid of the ‘x’ variable and just solve for ‘c’ like normal. Your main expression should look like this, I believe:
21.2x+c = 5.3(4x-2.6)
To substitute h the is out, you could write this if it feels better for you:
21x+c = y and 5.3(4x-2.6) = y
Hope this helps!
