Answer:
Step-by-step explanation:
I assume the problem is to graph the lines. The easiest is to pick two values of x and calculate y for each line. For example:
21. y = -4x + 5 I'll randomly choose vales of 1 and 2 for x and calculate y:
(1, 1) and (2, -3)
Now mark those two points and draw a straight line through them. It is an equation of a straight line, so we know this will be correct.
22. Same process:
(1,6) and (2,7)
23. (1,0) and (2,-3)
24. (1,-4) and (2,-6)
=====================
These are shown in the attachment. What's also shown is the second method of producing the lines: Use a graphing program such as DESMOS to plot the equations. The points aren't needed - they are there to demonstrate that the first approach also works.
Answer:
447 / 50
Step-by-step explanation:
447 / 50 Because if you divide it you will get 8.94 same answer
3/5x+9=-3
- 9 -9
-3 - 9 = -12
3/5x = -12
*5/3 *5/3
-12/1 * 5/3 = -60/3
-60/3 = - 20
Answer: x = -20
The 3 and the 2 are just to throw you off because you can just divide them out so the first zero is -9 because you have to subtract to find x with a multiplicity of 1 since there is no power (the small number) and the second is 93 since you add it to solve for x and multiplicity of 1. Is the second part asking to make an equation for it?
The answer is...
Decimal : 0.53
Fraction : 53/100
Hope this helps!
