Answer:
x = 1/12
Step-by-step explanation:
2/3x + 1/4 = (8x+3) /12 (create equivalent fractions with a denominator of 12)
23/3x - 1/3 = (23x - 1) /3 *(46/6x = 23/3x)
<u>8x + 3</u> = <u>23x - 1</u>
12 3
now cross-multiply:
3(8x + 3) = 12(23x - 1)
24x + 9 = 273x - 12
9 = 252x - 12
21 = 252x
x = 21/252 which reduces to 1/12
Hello!
8u - 8 = -7(u - 1) Given
8u - 8 = -7u + 7 Apply Distributive Property
15u - 8 = 7 Add 7u to both sides
15u = 15 Add 8 to both sides
u = 1 Divide both sides by 15
Answer:
u = 1
Hope this helps!
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
