The sign of a will be negative ~

let the value of be be ' -x ' , -x is a negative number (b = -x < 0)

[tex]\qquad \sf  \dashrightarrow \: a \times \frac{ - b}{b} [/tex]

[tex]\qquad \sf  \dashrightarrow \: a \times \frac{ - ( - x)}{ - x} [/tex]

[tex]\qquad \sf  \dashrightarrow \: a \times \frac{ x}{ - x} [/tex]

[tex]\qquad \sf  \dashrightarrow \:a \times - 1[/tex]

[tex] \qquad \sf  \dashrightarrow \:- a[/tex]

Therefore, the term a, has a negative sign unless it's value is substituted, I.e -a = 0 ( having no sign )

Step-by-step explanation:

y= -5x-3

-4+3 (-5x-3)=29

-4-15x-9=29

-4-9-29=15x

-42=15x

x= -2.8

Answer:

55 sq meters

Step-by-step explanation:

Area of big triangle 7x5=35/2

but there's two big triangle so 35/2 x 2 =35

area of small triangle 5x4=20/2 10

10 x 2 =20. And then combine 20+35=55

So the area is 55 sq meters.

The correct statement regarding the function plotted in the graph is:

C) The maximum value of the quadratic function occurs at y = 4.

When x = 0, y = -7, and when x = -5, y = 8, hence the rate of change(change in y divided by change in x) is given by:

R = [8 - (-7)]/-5 - 0 = 15/-5 = -3

It is concave down, hence it has only a maximum value at y = 4 and not a minimum value, hence option C is correct.

Answer: Statements 3, 4, 5

Step-by-step explanation:

Statement (3) is true because an interior angle and its exterior angle are supplementary.

Statement (4) is true by the exterior angle theorem.

Statement (5) because the sum of the angles of a triangle is 180 degrees.

Answer:

No, because triangle XYZ is not a right triangle.

Step-by-step explanation:

SOHCAHTOA (sin, cos, tan) can only work on right triangles. If a triangle is not a right triangle, you cannot use sin cos tan on it. This triangle is not a right triangle, so this is why you cannot fin the tangent ratio.

Answer:

-12.

Step-by-step explanation:

a^2 - 5a - 6

When a = 2 we have

2^2 - 5(2) - 6

= 4 - 10 - 6

= -12.

Answer:

Step-by-step explanation:

a²- 5a - 6

Substitute a for 2

(2)² - 5(2) - 6

Solve.

4 - 10 - 6 = -12

If a = 2, a²- 5a - 6 equals -12

Answer:

£336 more

Step-by-step explanation:

2100/5 = 420 One fifth of the total lottery.

Colin has four shares so 4X420 = 1680

He then splits it into 10 (2+3+5) parts. 1680/10=168

Wife: 168X5=840

Son: 168X3=504

Wife-Son 840-504=336

Answer:

336£

Step-by-step explanation:

To get the amount of money colin gets

(2100*4)/5=1680

Lets do a table:

2. 5. 3. Sum:10

(2*1680)/10. (5*1680)/10. (3*1680)/10

=336. =840. =504

We know, perimeter of the rectangle = 2(l +b)

where, l = length and b = breadth

Here, the perimeter of the rectangle is 48 kilometers and the height is of 10 kilometers. We can take height as the breadth.

=> Perimeter = 2(l + b)

=> 48 = 2(l + 10)

=> 48/2 = l + 10

=> l + 10 = 24

=> l = 24 - 10

=> l = 14 kilometers

Answer:

41

Step-by-step explanation:

5 integers with an average of 44

⇒ sum of the integers = 5 x 44 = 220

The median is the middle number when the numbers are put in order of smallest to largest.  So the integers are:  x  x  50  x  x

The modal integer is the one that occurs most frequently, so if the mode is 52, then at least 2 of the integer are 52.  Since the median is 50, the integers are:  x x 50 52 52

Therefore, the remaining two integers are less than 50.

The range is the difference between the largest integer and the smallest integer.  As we know that the largest integer is 52 and the range is 27, then the smallest integer is 52 - 27 = 25

25 x 50 52 52

To find the last unknown integer :

⇒ sum of the integers = 25 + 50 + 52 + 52 + x = 220

⇒ x = 41

Therefore, the integers are:

25, 41, 50, 52, 52
