For part A Amy's estimate is inaccurate because when adding fractions they must have the same denominators. Amy probably made the mistake of adding 1/4 and 1/3 without changing the denominators first which gave her 1/7. If she were to do it correctly then she would've ended up with 7/12 as her answer.

My work:

1/4=3/12
1/3=4/12
4/12+3/12=7/12

I hope this helps and if I gave any false information I apologize in advance.

HELP ME PLEASE 10 points!!!!!
atroni [7]

Answer:

x>9

Step-by-step explanation:

Tamika already has $55, which will stay the same independent of how much time passes. Since she deposits $5 per week, we can assign weeks a variable x. The amount of money in her account after x weeks is equal to 55+5x. If she must save over $100, we can create an inequality to solve for how many weeks must pass: 55+5x>100.

The question also asks to solve the inequality:

  1. 55+5x>100
  2. 5x>100-55 (Subtract 55 from each side)
  3. 5x>45
  4. x>9 (Divide each side by 5)

This solution tells us that Tamika must save for more than nine weeks to have more than $100 in her account.

lmk if i made an error, hope this helps!!

Use limits to find the area of the region bounded by the graph f(x)=4-2x^3 , the x-axis , and the vertical lines x=0 and x=1
gtnhenbr [62]

Answer:

\frac{7}{2} square units.

Step-by-step explanation:

We have to use limits to find the area of the region bounded by the graph f(x) = 4 - 2x^{3} , the x-axis, and the vertical lines x=0 and x=1.

So, the area will be

A = \int\limits^1_0 {(4 - 2x^{3})} \, dx

= [4x - \frac{x^{4}}{2} ]^{1} _{0}

= 4 - \frac{1}{2}

= \frac{7}{2} square units. (Answer)

Rewrite the following linear equation in slope-intercept form. y+4=-2(x-1)
romanna [79]

Answer:

y = -2x - 1

Step-by-step explanation:

Rewrite y + 7 = -2(x - 3) in slope-intercept form (which is y = mx + b):

First, perform the indicated multiplication:

y + 7 = -2x + 6

Combining the constants, we get

y = -2x - 1

This is the desired equation in slope-intercept form.  slope is -2 and y-intercept is -1.
