Mathematics
1 answer:
Alinara [238K]3 years ago
5 0

Answer:

x = 2

y = -1

Step-by-step explanation:

y = 2x - 5

y = -2x + 3

2x - 5 = -2x + 3

     4x = 8

       x = 2

y = 2(2) - 5

y = -1

How to construct a right scalene triangle using no given lengths with a ruler and a compass
11111nata11111 [884]
A scalene triangle contains three unequal in length sides. Therefore, a right scalene triangle can be constructed without the use of a ruler or compass. The 90-degree angle can be signified by a small box in the corner of the triangle that measures 90 degrees.

4 there are only red sweets and yellow sweets in a bag.
Taya2010 [7]

Using the probability concept, it is found that since the number of red sweets would be a decimal number, the probability cannot be \dfrac{7}{10}

<h3>What is probability?</h3>

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

In this problem:

  • In total, there are 8 + n sweets in the bag.
  • Of those, n are red.

The probability of red is:

p=\dfrac{n}{n+8}

Supposing, we solve for n:

\dfrac{n}{n+8} = \dfrac{7}{10}

10n = 7n + 56

3n = 56

n  =  56 / 3

n  =  18.67

Since the number of red sweets would be a decimal number, the probability cannot be 7 / 10

Question 2(Multiple Choice Worth 1 points) (06.01) Solve 2x + 5y = −13 3x − 4y = −8 (4, 1) (−4, 1) (4, −1) (−4, −1)
dlinn [17]
ANSWER

The solution is
(-4,-1)


EXPLANATION

The given equations are:

2x + 5y =  - 13...(1)

and

3x - 4y =  - 8...(2)


We multiply equation 1 by 3 to get,

6x + 15y =  - 39...(3)

We multiply equation 2 also by 2 to get,

6x - 8y =  - 16...(4)

We subtract equation 4 from equation 3 to get,


23y =  - 23
This implies that,

y =  - 1

We put this value of y into any of the equations say equation 2

3x - 4( - 1) =  - 8
Simplify

3x + 4 =  - 8
Group like terms
3x =  - 8 - 4
Simplify,

3x =  - 12

Divide both sides by 3 to get,

x =  - 4


Therefore the solution is
(-4,-1)

The correct answer is option D.
