Answer:
6- 8- 10 triangle with 10 as the hypotenuse
Step-by-step explanation:
In any right triangle the hypotenuse must be the longest side.
This is only true for the 6- 8- 10 with 10 as the hypotenuse.
Also using Pythagoras' identity
6² + 8² = 10²
We need to write the linear equation that is satisfied by (20,13) and (30,18).
$18 - $13 $5
The slope is m = --------------- = -------- = $0.50/mile
30 - 20 10
We need to find the y-intercept of this function. To do that, start with the slope-intercept form y = mx + b
and subst. the y and x values from one of the two given points. Suppose we choose (20,$13):
$13 = ($0.50/mile)(20 miles) + b
Then $13 = $10 + b, and b = $3.
There's an up-front charge of $3 just to step into the taxi.
The equation in question is y = ($0.50/mile)x + $3.00 (answer)
Answer:
a^2 + b^2 = c^2
Step-by-step explanation:
The distance from Abbotsford to Kelso is 17 km. That is your "a" value. The distance from Abbotsford to Hawick is 15 km.
Let us denote the years of Mary with M and the years that Al have with A.
<span>We know that the sum of Mary and Al's age is 48. So, we can write:
M+A=48 (1)
</span><span>We also know that twelve years ago, Mary was twice as old as Al.
So we can write:
M-12=2*A (2)
From the first equation (1): M=48-A
Let put this in the second equation:
48-A-12=2A
36=3A
A=12
M=48-12=36
