which point represents the solution to the system
3x-2y=12
2x+2y=3

a. (2,-2/3)
b. (3,-3/2)
c. (3,-2)
d. (2,2)

please explain how you got your answer.

Answers

Answer 1

Answer:

b

Step-by-step explanation:

[tex]3x - 2y = 12 \\ 2x + 2y = 3 \\ 2y = 3 - 2x \\ 3x - (3 - 2x) = 12 \\ 3x - 3 + 2x = 12 \\ 5x = 15 \\ x = 3 \\ 2y = 3 - 6 = - 3 \\ y = - \frac{3}{2} [/tex]

Quadrilateral MNPQ is shown.

Trapezoid M N P Q is divided into 4 triangles by N Q and M P, which intersect at point R inside the trapezoid. N P is parallel to M Q and M N is congruent to Q P. Angle N M P is 30 degrees and angle P M Q is 32 degrees. Segment Q R equals 4.1.

If MP = 5.9, what is RN?

(Round your answer to the nearest tenth. Write NA if there is not enough information given.)

Answers

Answer:4.1

Step-by-step explanation:

In the Quadrilateral MNPQ, if MP = 5.9, then RN = 1.8.

What is a trapezoid?

An open, flat object with four straight sides and one set of parallel sides is referred to as a trapezoid or trapezium. A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases.

Given:

Quadrilateral MNPQ is shown.

Trapezoid MNPQ is divided into 4 triangles by NQ and MP.

MQ is parallel to NP.

That means, MQ and NP always at the equal distance.

MN ≅ QP

So,

MP = QN

Now,

QN = QR + RN and QR = 4.1:

MP = QN

5.9 = 4.1 + RN

Then RN = 5.9 - 4.1 = 1.8

Therefore, the value of RN is 1.8.

Workout 2/7+1/5 and then simplyfy it

Answers

Answer:17/35

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(2/7, 1/5) = 35

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(2/7x5/5)+(1/5x7/7)=?

Complete the multiplication and the equation becomes

10/35+7/35=?

The two fractions now have like denominators so you can add the numerators.

Then:10+7

         ——- =17/35

            3

This fraction cannot be reduced.

Therefore:2/7+1/5=17/35

Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?​

Answers

Answer:

£3,692

Step-by-step explanation:

First four years

A = p(1 + r/n)^nt

P = £2350

r = 4.2% = 0.042

n = 1

t = 4

A = p(1 + r/n)^nt

= 2350(1 + 0.042/1)^1*4

= 2350(1 + 0.042)^4

= 2350(1.042)^4

= 2350(1.5789)

= 2770.42

A = £2770.42

Next 6 years

P = £2770.42

r = 4.9% = 0.049

n = 1

t = 6

A = p(1 + r/n)^nt

= 2770.42(1 + 0.049/1)^1*6

= 2770.42(1 + 0.049)^6

= 2770.42(1.049)^6

= 2770.42(1.3325)

= 3691.59

A = £3691.59

Approximately £3692

Step-by-step explanation:

The speed of the train is 320 miles per hour.

What is speed?

Speed is the ratio of the given distance and time.

It shows how fast an object is moving at a given time.

The formula is Distance / Time.

We can find the distance or time when the required values is given using this formula.

We have,

The speed of the TGV train can be calculated using the formula:

Speed = distance/time

where distance is given in miles and time is given in hours.

In this case,

The distance traveled by train is 800 miles, and the time taken to travel this distance is 2.5 hours.

Substituting these values into the formula, we get:

Speed = 800 miles / 2.5 hours

Simplifying the expression on the right-hand side, we get.

Speed = 320 miles per hour

Therefore,

The speed is 320 miles per hour.

Henry places £6000 in an account which pays 4.6% compound interest each year
Calculate the amount in his amount after 2 years

Answers

Answer:

£ 6,564.70

Step-by-step explanation:

Henry places £6000 in an account which pays 4.6% compound interest each year. Calculate the amount in his amount after 2 years

Compound Interest formula =

A = P(1 + r/n)^nt

A = Final Amounrt

P = Principal = £6,000

r = Interest rate = 4.6%

t = Time in years = 2 years

n = Compounding frequency = Yearly = 1

First, convert R percent to r a decimal

r = R/100

r = 4.6%/100

r = 0.046 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 6,000.00(1 + 0.046/1)^(1×2)

A = £ 6,564.70

The amount in his account after 2 years = £ 6,564.70
