3x-2y=-1 Y=-x+3 is (1,2) a solution of the system

Mathematics
1 answer:
Lisa [10]4 years ago
3 0

Answer:

Yes

Step-by-step explanation:

To be a solution of the system, it has to satisfy <em>both</em><em> the equations.</em>

<em />

Let's check first one:

3x - 2y = -1

3 (1) - 2(2) = 3 - 4 = -1

So correct (satisfies).

Now, 2nd one:

y = -x + 3

y = -(1) + 3

y = -1 +3

y = 2

Yes, this is satisfied.

Hence, (1,2) IS A SOLUTION OF THE SYSTEM

Find the volume of the composite figure. Round to the nearest tenth. The base of each pyramid is a square with a side length of
nataly862011 [7]

Answer:

75 cubic inches

Step-by-step explanation:

Given:

The base of each pyramid is a square with a side length of 5 inches

Height of of pyramid is 9 inches.

To find: volume of the pyramid

Solution:

As the base of each pyramid is a square with a side length of 5 inches,

length of the pyramid (l) = base of the pyramid (b) = 5 inches

Height of of pyramid (h) = 9 inches

Volume of the pyramid (V)=\frac{lbh}{3}

On putting values of l, b and h, we get

V=\frac{5\times 5\times 9}{3}=75 cubic inches

Every week, a car dealer ship sells at least 5 minivans. Write an inequality that represents this situation. Let c represent the
kvv77 [185]

Answer:

we conclude that an inequality 'c ≥ 5' denotes this situation.

Step-by-step explanation:

Given

  • A car dealer ship sells at least 5 minivans

When we talk about 'at least', it means we are talking about '≥' in terms of representing the 'at least' in inequality symbol.

For instance,

'm≥n' means 'm' is greater than or equal to 'n'.

It means 'm' is at least equal to 'n'.

Coming back to the question,

  • Let 'c' represent the number of minivans sold each week.

As the car dealer ship sells at least 5 minivans. so the

inequality will be: c ≥ 5

Thus, we conclude that an inequality 'c ≥ 5' denotes this situation.
