Answer: 82%
Explanation:
1898.3/2315 x 100
0.82 x 100 = 82%
The slope of the line is - 3/4
I got my ordered pairs by finding two points on the lines, an noting down their X and Y values.
Then I used the equation Y2 - Y1 (all over) X2 - X1 by plugging in the ordered pairs.
Finally, I solved and got -3/4!
See the attached picture below
Additionally, you can use rise over run, and count the rise and the run. In the image, the rise is three, and the run is four. The slope is negative, which leaves me to know that the answer is -3/4.
Hope this helps :)
How do you? easy = is an inequality
Answer:
x = 17
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
x² = 15² + 8² = 225 + 64 = 289 ( take square root of both sides )
x =
= 17
answers
question 1 = -0.5
question 2 = 6 - 3y
question 3 = 3x + 6
question 1
to evaluate (x + 1)/3 when x = -2.5, plug the value of x into the equation
(x + 1)/3
= (-2.5 + 1)/3
= (-1.5)/3
= -0.5
question 2
to solve this, distribute the 1/2 through the parentheses
(1/2) * (4 − 6y + 8)
= (1/2 * 4) + (1/2 * -6y) + (1/2 * 8)
= 2 + (-3y) + 4
= 6 - 3y
question 3
to solve this, distribute the 3 through the parentheses
3(x + 2)
= (3 * x) + (3 * 2)
= 3x + 6
<em>note - i tried to plug -2.5 into x + (1/3) for question 1, but the answer wasn't among the solutions, so i assumed the equation was (x+1)/3 instead since its answer was among the solutions</em>
