How many proportional relationships are shown in the coordinate plane below?

Mathematics
1 answer:
yarga [219]4 years ago
3 0

Answer:

D. 3

Step-by-step explanation:

We can see from the graph that there are 3 lines. All 3 lines look linear, and if a line is linear, <em>x</em> and <em>y</em> are proportional. Therefore, if all 3 lines are linear, then we have 3 proportional relationships.

Find the slope and y-intercepts <br> f(x)= -1/2x - 2
gavmur [86]

Answer:

slope: -1/2

y-intercept: -2

Step-by-step explanation:

f(x) = mx+b

m is slope

b is the y-intercept

so

if f(x) = -1/2x - 2

then

the slope or m is -1/2

and the y-intercept or b is -2

Find the sum of all 11 terms of an AP whose middlemost terms is 30?
Bond [772]

Let the difference between consecutive terms be D. If the middle term is 30, then the term before it is 30-D, and the term after it is 30+D. So the sum of these three terms would be (30-D) + 30 + (30+D) = 3*30.

Extending this sum to include all 11 terms centered around 30, we see that any addition of D is canceled by a balanced subtraction, leaving you with 11 copies of 30. So the value of the sum is 11*30 = 330.

Lerok [7]

3. Here we use the formula

A = P ( 1 + \frac{r}{n} )^ {nt}

And we have the following values given

P = $23400, r = 3%=0.03,n =2, t=10 years

So we will get

A = 23400(1+ \frac{0.03}{2} )^{2*10}&#10;\\&#10;A = 23400( \frac{2.03}{2} )^{20} = $31516.52

Question 4.

In this question , we have

P = $2310, R = 3.5% = 0.035 ,&#10;\\&#10;Number \ of \ days \ from \ april \12 to July \ 5 = 30+31+23 = 84 days

A = 2310(1+ \frac{0.035}{365})^{84}  = $2328.68

Interest is the difference of amount and principal, that is

I = 2328.68-2310 = $18.68
