<h2>Answer:</h2>

The point that lie in the solution set of the given system of inequalities is:

                          (0,0)

<h2>Step-by-step explanation:</h2>

We are given a system of inequality as:

          3x+y ≥ -3---------------(1)

and    x+2y ≤ 4----------------(2)

From the given points we will check which satisfies both the inequality and hence the one which satisfies will be a solution.

a)

                (5,0)

on putting in inequality (1) we get:

  15≥  -3

and from inequality (2) we get:

             5≤4

which is incorrect.

Hence, option: a is not a solution.

b)

                 (-2,0)

on putting in inequality (1) we get:

        -6 ≥ -3

which is incorrect( since -6<-3)

Hence, option: b is incorrect.

c)

                          (0,3)

on putting in inequality (1) we get:

                    3 ≥ -3

which is true

on putting in inequality (2) we get:

         6 ≤ 4

which is incorrect.

Hence, option: c is false.

d)

             (0,0)

on putting in inequality (1) we get:

   0 ≥ -3

which is  a true expression.

on putting in inequality (2) we get:

              0 ≤ 4

which is a true expression.

Hence, the point (0,0) will lie in the solution set.

Answer:

y=-3/2x+6

Step-by-step explanation:

You can find the slope by taking two points on the graph, and making the one that occurs earlier in the graph (from left to right) the first point (x1, y1) and the one that occurs later in the graph the second point (x2, y2). The equation is m (or slope)=(y2-y1)/(x2-x1). I took the first two points in the table for this. m=(12-18)/-4-(-8)

the double negative on the bottom becomes an addition=> (12-18)/(-4+8)

the top simplifies to be -6 and the bottom simplifies to 4=>-6/4

this fraction can be reduced to -3/2, which is the slope of the graph.

Now, use point slope form (y-y1=m(x-x1)) to find the equation of the graph. Plug any coordinate on the graph in for x1 and y1 here. It should be correct as long as it is a point on the graph, but I am using the point (-8, 18) here.

=>y-18=-3/2(x-(-8))

the double negative in the parentheses becomes a positive=> y-18=-3/2(x+8)

distribute the -3/2 to every term in the parentheses=> y-18=-3/2x-12

add 18 to both sides, cancelling out the -18 on the left side of the equation=>y=-3/2x+6 (-12+18=6 to get 6 for b).

Therefore, the equation is y=-3/2x+6

Mia wants to borrow £6000 and repay it, with interest, after two years. she sees two offers for loans: offer 1 compound interest
AURORKA [14]

Answer:

she is wrong, offer 2 results in lower interests

Step-by-step explanation:

total amount paid if offer 1 is accepted:

$6,000 x (1 + 3%)² = $6,000 x 1.0609 = $6,365.40

she will pay $365.40 in interests

total amount paid if offer 2 is accepted:

($6,000 x 1.01) x 1.05 = $6,060 x 1.05 = $6,363

she will pay $363 in interests

Compounding interest refers to interest that earns more interest itself, e.g. in the first offer, the $180 of interests charged for the first year will earn $5.40 in extra interests. While offer 2 only charges $60 in interests during the first year which will in turn earn $3 of interests. The difference between both offers is that interest charges in offer 1 earn more interests than the interest in offer 2 = $5.40 - $3 = $2.40

The weight of a full steel bead tire is approximately 800
AleksAgata [21]

Answer: 1.76

1.54

Step-by-step explanation:

we have to divide 800 by 453.592, and the result is 1.763699... rounding it: 1.76

now we do the same for 700 :

700 divided by 453.592 is 1.5432... so rounding it down: 1.54
