Answer:

False

Step-by-step explanation:

This is false. We can disprove this by plugging in the number into the function f(x) = lnx

f(0) = ln0

Since e^{- \infty} = 0, ln0 = -\infty

This is not 0 so f(0) cannot be equal to 0, thus disproving the statement.

Vita saved $72 last December. This amount represents 2/9 of the total amount she saved last year. What is the total amount Vita
GrogVix [38]
\dfrac{2}{9} \text { of the saving} = \$72

-----------------------------------------------
Find 1/9 :
-----------------------------------------------
\dfrac{1}{9} \text { of the saving} = \$72 \div 2

\dfrac{1}{9} \text { of the saving} = \$36

-----------------------------------------------
Find 9/9 :
-----------------------------------------------
\dfrac{9}{9} \text { of the saving} = \$36 \times 9

\dfrac{9}{9} \text { of the saving} = \$324

-----------------------------------------------
Answer: The total amount is $324.

Need help with problems 16 and 17, please? I'll do brainiac
natali 33 [55]

Answer: 16) y=-0.5x+3 and 17) y=2x-3

Step-by-step explanation:

16: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.

Since y=3 at x=0, the y-intercept is (0,3), and b=3.

Slope=\frac{y_{2} -y_{1} }{x_{2}-x_{1}  } where (x_{1} ,y_{1}) and (x_{2} ,y_{2}) are two points on the line. Choose (0,3) and (2,2):

Slope=\frac{2-3}{2-0}=-0.5

Plug m=-0.5 and b=3 into y=mx+b:

y=-0.5x+3

17: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.

Because y=-3 at x=0, the y-intercept is (0,-3), and b=-3.

Slope=\frac{y_{2} -y_{1} }{x_{2}-x_{1}  } where (x_{1} ,y_{1}) and (x_{2} ,y_{2}) are two points on the line. Choose (0,-3) and (1,-1):

Slope=\frac{-3-(-1)}{0-1}=\frac{-2}{-1}=2

Plug m=2 and b=-3 into y=mx+b:

y=2x-3

Which inequality represents all the solutions of -5x + 5 ≥ 160 − 10x? A. x ≤ -33 B. x ≥ 33 C. x ≥ 31 D. x ≤ 31
ikadub [295]

Answer:

The answer is B.

Step-by-step explanation:

Solve for x.

-5x + 5 \geq 160 - 10x

Add 10x to both sides, and subtract 5 from both sides.

5x \geq 155

Now, divide by 5.

x \geq 31          is the answer
