Answer:

80 squared units.

Step-by-step explanation:

7 × 8 = 56 u squared for the triangles

you don't need to divide by two because there are two triangles.

3 × 8 = 24 u squared for the rectangle

56 + 24 = 80 squared u

Answer:

The factors of a number are all of the numbers that will divide into that number with no remainder. The prime factors of a number are the prime numbers that must be multiplied together to give the number. For example: The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The prime factors of 30 are 2, 3, and 5.

Answer:

Step-by-step explanation:

7(-4x - 1) = 49

-28x - 7 =49

-28x = 49 + 7 = 56

x = 56/(-28) = -2

Answer:

7 x - 4x = - 28x

7 x - 1 = - 7

-28x - 7 = 49

+7 both sides

-28x = 56

÷ - 28

x = 56/-28

x = - 2

I substitute to double check my answer:

- 4x

-4x-2 =8

7(8- 1)

7x 8 = 56

7 x - 1 = - 7

56-7= 49

Given :-

To Find :-

Solution :-

The given expression is [tex] /[/tex]

→ aₙ=43-3(n-1)

where n > 0

Finding the first term :

Substituting n = 1 , we have ,

→ T1 = 43 - 3(1-1)

→ T1 = 43 - 3*0

→ T1 = 43 - 0 = 43

Finding the second term :

Substituting n = 2 , we have,

→ T2 = 43 -3(2-1)

→ T2 = 43 -3*1

→ T2 = 43 -3 = 40

Finding the third term :

Substituting n = 3 , we have,

→ T3 = 43 -3(3-1)

→ T3 = 43 -3*2

→ T3 = 43 -6 = 37

Finding the fourth term :

→ T4 = 43 -3(4-1)

→ T4 = 43 -3*3

→ T4 = 43-9 = 34

Hence the first four terms of the sequence are 43 , 40 , 37 and 34 .

Answer:

Slope = -5/8

Step-by-step explanation:

Take 2 points from the graph where the line is. Point 1: (1 , 6). Point 2: (9 , 1).

We are going to use the formula for finding the slope of a line now.

y2 - y1/x2 - x1 = 1 - 6/9 - 1 = -5/8

Slope = -5/8

Answer:

5/2

Step-by-step explanation:

I used coordinate (-4, -2) and (-2, 3)

Slope=change in y/change in x

Answer:

Step-by-step explanation:

It is given

2x−3y=5

we can write it as

3y=2x−5

So we get

y=32x−5​

Substituting x=4 in the given equation

y=32(4)−5​

So we get

Y=38−5​

y=33​

By division we get

y=1

Substituting x=−2 in the given equation

y=32(−2)−5​

So we get

y=3−4−5​

y=3−9​

By division we get

y=−3

x 4       -2

y      1        -3

Now draw a graph using the points (4,1) and (−2,3)

Join the point through a line and find the value of y

(i) Based on the graph

consider x=4 on X-axis

Now the line joining the two points and a point on the Y-axis gives the value of y

Therefore,when x=4 the value of y=1

(ii) Based on the graph,

Consider y=3 on Y-axis

Now the line joining the two points and a point on the X-axis the value of x

Therefore, when y=3 the value of x=7

Let x represent the number of calls received on the second evening.

The number of calls received on the first evening is x - 10.

The number of calls received on the third evening is 2x.

The sum of calls received on the three evenings is (x - 10) + x + 2x, and this is equal to 50:

(x - 10) + x + 2x = 50

4x - 10 = 50

4x = 50 + 10

4x = 60

x = 60/4

x = 15

The number of calls received on each evening is then:

First evening: x - 10 = 15 - 10 = 5

Second evening: x = 15

Third evening: 2x = 2(15) = 30

Check: 5 + 15 + 30 = 60

Answer:

5. (x,y) = (2.3)

Step-by-step explanation:

1/2x + 2 = x+1

x = 2

y = 2+1

y = 3

(x,y) + (2,3)

{3 = 1/2 x 2 + 2

{3 = 2 + 1

{3 = 3

{3 = 3

Answer:

  3. no solution

  5. (x, y) = (2, 3)

Step-by-step explanation:

  -5x +y = 1

  -10x +2y = -2

Multiply the first equation by -2 and add the second equation:

  -2(-5x +y) +(-10x +2y) = -2(1) +(-2)

  10x -2y -10x +2y = -2 -2 . . . . eliminate parentheses

  0 = -4 . . . . . . . . . no variable values will make this true: NO SOLUTION

(The lines graph as parallel lines.)

__

  y = 1/2x +2

  y = x +1

Subtract the first equation from the second:

  (y) -(y) = (x +1) -(1/2x +2)

  0 = 1/2x -1

  0 = x -2

  2 = x

  y = x +1 = 2 +1 = 3 . . . . use the second equation to find y

The solution is (x, y) = (2, 3).
