Answer:

the greater the number pf Zeroes after the point, the lower the value of the number, so option 11.003

Answer:

y = - 4x - 7

Step-by-step explanation:

Line is passing through the point (-1, - 3) and has a slope (m) = - 4

[tex]y - ( - 3) = - 4 \{x - ( - 1) \} \\ \\ y + 3 = - 4(x + 1) \\ \\ y + 3 = - 4x - 4 \\ \\ y = - 4x - 4 - 3 \\ \\ y = - 4x - 7[/tex]

Answer:

9(4)+4

Step-by-step explanation:

Answer: 9x+36

Step-by-step explanation:

9(x+4)

9x+(9x4)

9x+36

Answer:

x = 3, y = 2

Step-by-step explanation:

[tex]360 = {2}^{x} \times {3}^{y} \times 5 \\ \\ \frac{360}{5} ={2}^{x} \times {3}^{y} \\ \\ 72 = {2}^{x} \times {3}^{y} \\ \\ 8\times 9 = {2}^{x} \times {3}^{y} \\ \\ {2}^{3} \times {3}^{2} = {2}^{x} \times {3}^{y} \\ \\ equating \: like \: terms \: on \: both \: sides \\ {2}^{3} = {2}^{x} \\ \\ \implies \: x = 3 \\ \\ {3}^{2} = {3}^{y} \\ \\ \implies \: y= 2 \\ \\[/tex]

Answer:

Step-by-step explanation:

1. I can't see the first one very well.

2. Find the area of each triangle by doing 1/2 * base * height. This should give you [tex]40m^{2}[/tex]

3. The area of a trapezium is [tex]\frac{1}{2} (a+b)h[/tex] where a is the top edge, b is the bottom edge and h is the height.

We can work out the bottom edge using pythagoras - split the trapezium into 2 triangles on each side and a rectangle in the middle. This gives you the length of the bottom edge which is 2 + 2 + 2 = 6'

Work out the area by doing 1/2(2+6)4 = 16' squared.

4.Split this shape into a triangle and rectangle. We know the right hand edge of the triangle= 9-4 = 5'.

To find the bottom edge of the triangle, use tanθ=opposite/adjacent line. Therefore tan45=bottom edge of triangle/5'. tan 45=1 therefore bottom edge = 5'.

The bottom edge of triangle gives us the height; use 1/2(a+b)h to work out the area of the trapezium. 1/2(4+9)5 = 32.5' squared

Step-by-step explanation:

150 + 150 + x = 360

x = 60

∠ADC = 60°

they are the same

Answer:

x^2 -4x -21

Step-by-step explanation:

Here, we want to write a quadratic polynomial

We have the sum as -4

Let us have x as the variable

so the sum of the variables is -4x

while the product is -21 x^2

Two factors of 21 that can work here is -7x and 3x

So we have

x^2 - 7x + 3x -21

= x^2 -4x -21

Answer:

Step-by-step explanation:

A function can only have one y value for any given x value. If there is more than one value of y for a single x value it is said to have failed the ‘vertical line test.

Since there are points (-7,8) and (-7,-3) this is NOT a function.

The first option is correct. As long as the signs remain the same for the specific terms, it's correct.

x+y+z is equivalent to z+y+x

Answer:

n * 3 +12 / 3

Step-by-step explanation:

One third of the result of a number * 3 is once the number is multiplied by 3, the number is then added to 12, because the result is divided by 3, meaning you must multiply by 3 first, then add 12, and then divide by 3.

Equation formed will be:

1/3 (3x + 12)

Answer:

4.18 × 10^ 2

Step-by-step explanation:

Answer:

Step-by-step explanation:

I am assuming that number began with a decimal point.

Count how many places the decimal must move to the right to get past the 4, in this case the decimal must move 5 places. This means you are multiplying by 10^5. So the number in scientific notation becomes

4.18X10^(-5)

Answer: there is no solution

Step-by-step explanation: 1/4z — 13 is not the same as 1/4 + 13

Say z = 1 that would simplify as -12 3/4 = 13 1/4 they are not the same so there is no solution

Answer:

I think the answer is C. Its not B or D though

Step-by-step explanation:

Answer:

1) [tex]49 {a}^{2} - 16 {b}^{2} [/tex]

2) [tex]251502[/tex]

Step-by-step explanation:

a) Question :-[tex](7a - 4b)(7a + 4b)[/tex]

Identity used here :-[tex](a + b)(a - b) = {a}^{2} - {b}^{2} [/tex]

So,

[tex](7a + 4b)(7a - 4b)[/tex]

[tex]=> {(7a)}^{2} - {(4b)}^{2} [/tex]

[tex]=> 49 {a}^{2} - 16 {b}^{2} [/tex]

b) Question :- [tex]501 \times 502[/tex]

Identity used here :-[tex](x + a)(x + b) = {x}^{2} + (a + b)x + ab[/tex]

So,

[tex]501 \times 502 = (500 + 1)(500 + 2)[/tex]

[tex] = > {(500)}^{2} + (1 + 2)500 + 1 \times 2[/tex]

[tex] = > 250000 + 1500 + 2[/tex]

[tex] = > 251502[/tex]
