-5x - 5 = 3x + 19
---Move the x's to one side
-5x - 3x - 5 = 3x - 3x + 19
-8x - 5 = 19
---Isolate the -8x by removing the -5 from the left side
-8x - 5 + 5 = 19 + 5
-8x = 24
---Divide both sides by -8 to get x by itself
x = -3
Hope this helps!
Answer:
Step-by-step explanation:
The form, y = mx + b is the slope intercept form of a straight line.
Where b = intercept
m = slope = (change in the value of y in the vertical axis) / (change in the value of x in the horizontal axis.
Slope = (y2 - y1)/(x2 - x1)
y2 represents final value of y = - 3
y1 represents initial value of y = 3
x2 represents final value of x = 3
x1 represents initial value of x = 0
Therefore,
slope = (- 3 - 3)/(3 - 0) = - 6/3 = - 2
To determine the intercept, we would substitute m = - 2, x = 3 and y = -3 into y = mx + b. It becomes
- 3 = - 2 × 3 + b = - 6 + b
b = - 3 + 6 = 3
The equation becomes
y = - 3x + 3
Real quick so I can sleep. it is because obtuse is over 90 degrees
Answer:
The answer is A.
Step-by-step explanation:
just fyi, if you spend x points on question, each user gets x/2 points (rounded up or down, I don't remember)
simple interest formula is
I=PRT
I=interest
P=principal
R=rate in decimal
T=time in years
assuming you mean that the principal is $2500 and not 2500 cents or 2500 of some other currency
interest=500
R=4%=0.04
I=PRT
500=(2500)(0.04)(T)
500=100T
divide both sides by 100
5=T
answer is 5 years
C is answer
