-4*2(3x-7)
-8(3x-7)
8 times 4 is 24 so it would be negative 24
so 3 times 16.3=48.9 then you add 7 which rounds it off it 56
so x is 16.3 thats how you get this expession
-24x +56
Answer:
slope = 1 , y- intercept = - 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = x - 5 is in this form
with slope m = 1 and y- intercept c = - 5
√x² - 4 + x²/x² + 1
x - 2 + x²/x² + 1
<u>x - 2</u> + <u> x² </u>
1 x² + 1
<u>(x - 2)(x² + 1)</u> +<u> x² </u>
(1)(x² + 1) x² + 1
<u>x³ + x - 2x² - 2</u> + <u> x² </u>
x² + 1 x² + 1
<u>x³ - 2x² + x² + x - 2</u>
x² + 1
<u>x³ - x² + x - 2</u>
x² + 1
x³ + x - 2

Answer: False, there are actually 900 different three-digit numbers
========================================================
Explanation:
The three digit numbers span from 100 to 999, including both endpoints.
This means we have 999-100+1 = 900 different three-digit numbers.
You subtract the endpoints (large-small) and add 1 to include the lower endpoint.
Here's a smaller example of why this works: say you had the set {1,2,3,4} and we wanted to count the number of items in this set. Clearly there are 4 items. Note how subtracting the endpoints 4-1 gets us 3 instead, so we add on 1 to include that left endpoint.
