Find the slope of the function f ( x ) = 5x/2 + 3, by the definition of limit. Express answer as a fraction using the "/" key as

musickatia [10]

$\huge{\boxed{\frac{5}{2}}}$

Slope-intercept form is $f(x)=mx+b$ , where $m$ is the slope and $b$ is the y-intercept.

$\frac{5x}{2}=\frac{5}{2}x$ , so change the equation to represent this. $f(x)=\frac{5}{2}x+3$

Great! Now the function is in slope-intercept form, so we can just see that $m$ , or the slope, is equal to $\boxed{\frac{5}{2}}$

A student is saving money to buy a video game. The student currently has $20 and plans to save $10 every month. Write a function

4vir4ik [10]

Answer:

y = amount saved in dollars

x = months

Since the student already has $20 dollars saved (20) and plans to save $10 per month (10x), the equation so far is y = 20 + 10x.

You can use this to solve questions based of the equation/situation by filling in any numbers you are given where the variables are.

Hope this helps! :)

17. Find m2 USW if m_ USW = 7x - 34 and m2 TSR = 4x + 29.

SVEN [57.7K]

Answer:

Step-by-step explanation:

Find the diagram attached. From the diagram, we can see that;

<USW = <TSR (vertically opposite angles)

Given

<USW = 7x-34

<TSR = 4x+29

Equate

7x-34 = 4x+29

7x-4x = 29+34

3x = 63

x = 63/3

x = 21°

Find <USW

<USW =7x-34

<USW =7(21)-34

<USW = 147-34

<USW = 113°

Hence the measure of <USW is 113°

If the length of a rectangle is 120 m and the diagonal measures 130 m what is the perimeter and area of the rectangle

Leviafan [203]

Answer:

Step-by-step explanation:

width=√(130²-120²)=√[10²(13²-12²)]=10√(13+12)(13-12)=10√(1×25)=10×5=50 m

perimeter=2(120+50)=2×170=340 m

area=120×50=6000 m²
