Answer:
Keith travelled 4.2 miles if he had ridden directly to the pool
Step-by-step explanation:
Given: In a right triangle, the distance from the angle with measure 90 degrees to Keith's pool is 3 miles, and the distance to the pool is 3 miles.
To find: Distance travelled by Keith if he moved directly from house to swimming pool
Solution:
ΔABC is a right angled triangle.
Using Pythagoras theorem, square of hypotenuse is equal to sum of squares of base and perpendicular
Keith travelled 4.2 miles if he had ridden directly to the pool
Answer:
Step-by-step explanation:
2x²-13x+21+6x²+29x-5
=8x²+16x+16
2.9 because 1.16 plus 1.16 is 2.32. If each is a pound split it in half and add 2.32 it and y'all get 2.9
Answer:
Step-by-step explanation:
We want to find the inverse of
We interchange x and y.
We need to solve for y, so let us multiply through by 2.
Subtract 6 from both sides.
Therefore the required inverse is
Answer:
2.5
Step-by-step explanation:
The equation will have infinite solutions when it is a tautology--when both sides say exactly the same thing.
Eliminate parentheses, match coefficients, and solve for b.
ax +ab = 4x +10
a = 4 . . . . . . coefficient of x
ab = 10 . . . . constant
Since we know a, we can find b:
4b = 10
b = 10/4 . . . . . . . divide by 4
b = 5/2 = 2.5 . . .express in your favorite form
