Answer:
The first term is 2.5
Step-by-step explanation:
The first term is 2.5 and it decreases 0.5 each time.
x= -0.5n+2.5
Answer:
Error was at the fourth line: 12 = 16x
Correct solution: x = ½
Step-by-step explanation:
Let's solve the equation step by step to find the correct solution, and also, to find out at which line Cam made a mistake.
10 - 2x = 19x + 2 - 5x (given)
10 - 2x = 19x - 5x + 2
10 - 2x = 14x + 2
Add 2x to both sides
10 - 2x + 2x = 14x + 2 + 2x
10 = 14x + 2x + 2
10 = 16x + 2
Subtract 2 from both sides
10 - 2 = 16x + 2 - 2
8 = 16x (this is where Cam made an error, at the fourth line. He wrote: 12 = 16x. It seems Can only subtracted 2 from the right, then added 2 to the left. Subtraction property of equality was not properly done.)
Proceeding further with our calculation, we would divide both sides by 16
8/16 = 16x/16
½ = x
x = ½.
Answer:
3rd option
Step-by-step explanation:
The range are the values covered on the y- axis
The lowest value is - 2
The highest value is 6
Both points have a solid circle on them indicating y can equal those values
range { y : - 2 ≤ y ≤ 6 }
Answer:
(3;0)
(0;15)
y=-5x+15
Step-by-step explanation:
x-intercept
-5x–0=-15
-5x=-15
-5x/-5=-15/-5
x=3 》》(3;0)
y-intercept
-5(0)-y=-15
y=15 》》 (0;15)
slope intercept form
y=mx+b
m=Y2–Y1/X2–X1
=15–0/0–3
=15/-3
=-5
evalute (0;15) & m=-5 in y=mx+b
15=-5(0)+b
15=b
so
y=-5x+15
