The equation for this is 23x5=115
Answer:
B.
Step-by-step explanation:
First convert the equation to slope-intercept form:
2x - 5y = 7
-5y = -2x + 7
y = 2/5 x - 7/5
So the slope of the given line is 2/5.
So the slope of a perpendicular line will be -1/ 2/5 = -5/2.
Take B:
5x + 2y = 3
2y = -5x + 3
y = -5/2.
So its B.
Answer:
0.70p
Step-by-step explanation:
"30% off" means paying only 70% of the original sales price (subtracting 30% from 100% yields 70%). Next, find the decimal equivalent of 70%:
It is 0.70. Finally, multiply the price p by 0.70: 0.70p (Answer b)
