1.) The slope equals -5/4 because if we change the 4x+5y=-2 to a slope-intercept form then we can easily see the m (slope) and from that you switch the sign of the number and switch the numbers (ex. -1/2 = 2, 3 = -1/3). To get to the slope-intercept, you subtract 4x from both sides to get 5y=4x-2, then divide both sides by the 5 next to y to get y=4/5x-2/5.
2.) The equation would be y=1/3x+5 because if make the equation into a slope-intercept form by adding the x to both sides to get 3y=x+6 then divide both sides by 3 for y=1/3+2, then we can see the slope is 1/3 and since parallel lines have the same slope, you know the new line's slope is 1/3. Now if we put the slope into a new equation you'll get y=1/3x+b, so you then substitute the point's x and y in the equation for 5=1/3(3)+b, and then solve for b which is 5. Putting the y-intercept (b) and the slope into an equation, you get y=1/3x+5.
Answer:
4x2+7x−1
Step-by-step explanation:
The experimental probability of the computer generating a 2 is 20%.
<h3>What is the experimental probability?</h3>
The experimental probability determines the odds an event would happen based on the results of an experiment.
Experimental probability = ( number of times a 2 was generated / total number of numbers generated) x 100
(16 / 80) x 100 = 20%

Answer:216
Step-by-step explanation:
Answer:
1/5, 1/2, 8/10
Step-by-step explanation:
If you change all the fractions into x/10, you get:
1/5 = 2/10
1/2 = 5/10
8/10 = 8/10
2/10 < 5/10 < 8/10
hope this helps :)
