Answer:
21
Here’s legitimate proof that 9+10=21
(9 + 10) (base x) = 21 (base y)
9(1) + [1(x) + 0(1)] = 2(y) + 1
Simplify and solve for y:
2y = 8 + x
y = 4 + x/2
Since we have number bases, we want x and y to be positive integers. The term x/2 requires that x be a positive even number.
Also since 9 is in base x, we have x ≥ 10, as the digit 9 would not be used for a base 9 or smaller.
Thus we have the pairs of solutions:
x = 10, so y = 9
x = 12, so y = 10
x = 14, so y = 12
…
x, y = 4 + x/2 … Therefore 9+10=21!
Answer:
This does show the equation in slope-intercept form
Step-by-step explanation:
Slope intercept form is written as:
y = mx + b
In which, the m is slope and b is the intercept. In this case the slope would be -4/7 and the intercept would be 9.
Answer:
4^12 y^24
Step-by-step explanation:
(16y^5/4y^3)^12
Simplify inside the parentheses
(16/4 * y^5/y^3) ^ 12
When dividing the bases to the exponent, we keep the base and subtract the exponent
(4 y^(5-3)) ^12
(4 y^2) ^12
Remember (ab)^c = a^c * b^c
4^12 y^2^12
When we have a power to a power, we can multiply the exponents
a^b^c =a^(b*c)
4^12 y^(2*12)
4^12 y^24
Answer:
5000
Step-by-step explanation:
Is means equals and of means multiply
.1% * N = 5
Change to decimal form
.001 N = 5
Divide each side by .001
.001N/.001 = 5/.001
N =5000
