Answer:
x = 10
x = -10
Step-by-step explanation:
x = 10
We can start by comparing the tens digit, as each number has two digits.
29 vs 10
2 vs 1
2 is greater than 1; therefore, as the biggest digit is larger and each number has the same amount of digits, 29 > 10 and x= 10 < 29
x = -10
29 is positive, and -10 is negative. Any negative number is smaller than any positive number, so x = -10 < 29
First you distribute the 3
(3x-12) (x+5)=0
then you set each equation equal to zero
3x-12=0 & x+5=0
then you solve for x
x =4, -5
It would be equal to 4
Hope this helps!
This response is based upon your having had some background in calculus. "dx" is not introduced before that.
Take a look at the sample function y = f(x) = x^2 + 9. Here x is the independent variable; the dependent variable y changes with x.
Now, for a big jump: we consider finding the area under a curve (graph) between x = a and x = b. We subdivide that interval [a,b] into n vertical slices of area. Each of those slices has its own area: f(x)*dx, where dx represents the width of such subarea. f(x)*dx is the actual subarea. To find the total area under the curve f(x) between x= a and x = b, we add up all of these individual subareas between x = a and x = b. Note that the subinterval width is
b-a
dx = ---------- , and that dx becomes smaller and smaller as the number of
n subintervals increases.
Once again, this all makes sense only if you've begun calculus (particularly integral calculus). Do not try to relate it to earlier math courses.
