Answer:
gradient m = - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
y = - x - 3 ← is in slope- intercept form
with gradient m = - 1
The minimum speed will be calculated as follows:
Time taken from Toledo to Elkhart=(8.15-5.45)=2 1/2 hours
Distance=136 miles
thus the speed between Toledo and Elkhart= 136 miles/2.5=54.4 mph
Distance between Toledo and Chicago is 244 miles
Distance between Elkhart and Chicago=244-136=108 miles
time taken to travel between Elkhart and Chicago assuming that I left Elkhart at exactly 8:15 and reach at 10.30:
=10:30-8:15=2.25 hours
thus the speed will be:
speed=(108)/(2.25)=48 mph
Thus for us to get to Chicago by 10:30 a.m we should drive at 48 mph
Answer:
POOOOOOOOOOP KAKAKAKA
Step-by-step explanation:
The expression x³ - 64 can be rewritten using difference of cubes is; (x - 4)(x² + 4x + 16)
<h3>How to write an expression as difference of cubes?</h3>
Difference of cubes can be rewritten in the form of;
a³ – b³ = (a – b)(a² + ab + b²)
So in this question, we are given;
x³ - 64 = x³ - (4)³
where a = x and b = 4
This gives us;
(x - 4)(x² + 4x + 4²)
⇒ (x - 4)(x² + 4x + 16)

Answer:
$422.50
Step-by-step explanation:
If the bike is marked down by 35% then the final sale price will be 65% of the original price (since 100% - 35% = 65%).
Convert 65% into a decimal: 65% = 65/100 = 0.65
Therefore, 65% of $650 = 0.65 × 650 = $422.50
