Step-by-step explanation:
2x+3y=-18
3y=-2x-18
y=(-2x-18)/3
The y-intercept is the value of y when x=0 so
y-intercept=-18/3=-6, technically the point (0.-6)
The x-intercept occurs when y=0 so
(-2x-18)/3=0
-2x-18=0
-2x=18
x=-9 So the x-intercept is the point (-9,0)
So x-intercept is -9 and y-intercept is -6
Answer:
B. x=y
Step-by-step explanation:
A 5% tax charge is equivalent to multiply the current price by 1.05. On the other hand, a 5% discount is equivalent to substrace the current the 5% of it, so in the end, you multiply the current price by 0.95.
For X we should multiply first by 0.95, then by 1.05
For Y we multiply first by 1.05, then by 0.95
Hence, if L = price list, we have
- x = L*0.95*1.05 = 0.9975L
- y = L*1.05*0.95 = 0.9975L
- z = L
As a result, x=y<z. Option B is correct.
Note that applying discount first or charging taxes first doesnt matter because the order of the factors doesnt ater the product.
Answer:
x > 125
Step-by-step explanation:
x/25 > 5
Multiply both sides by 25
x/25 × 25 > 5 × 25
x > 125
5/8 in decimal form is 0.625<span />
