Answer:
First one:
a discount of 15% and then 10% and then 15% off that amount
Step-by-step explanation:
15% discount means 100-15 = 85% is to be paid
10% discount means 100-10 = 90% is to be paid
25% discount means 100-25 = 75% is to be paid
Let X be the cost before discount
1st offer:
85% of 90% of 85% of X
(85/100) × (90/100) × (85/100) × X
= 0.65025X
2nd offer:
75% of X
(75/100) × X
= 0.75X
Since 0.65025 < 0.75,
Offer 1 is better
Answer:B
Step-by-step explanation:
2/7(x−2)=4x
2/7x+−4/7=4x
2/7x+−4/7
−4x=4x−4x
−26/7x+−4/7=0
−26/7x+−4/7+4/7=0+4/7−26/7x=4/7
(7−26)*(−26/7x)=(7/−26)*(4/7)
x=−2/13
Answer:
y = negative (2) Superscript x Baseline + 3
Step-by-step explanation:
An exponential function has a range of y > 0. In order for it to have a range of y < 3, it must be reflected across the x-axis (given a negative multiplier) and must be translated upward 3 units.
That is, for some exponential function y = b^x, you must have something of the form ...
y = -a·b^x +3
Only one answer choice has this form:
Answer:
x = 67°
Step-by-step explanation:
x = m<K (corresponding angles are congruent)
m<K = 180 - (46 + 67) (sum of triangle)
m<K = 67°
Therefore,
x = m<K = 67°
x = 67°
