What is the common difference of the sequence 8, 4, 0, -4, -16?

Answer:

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.

Answer:

(13,-6)

Step-by-step explanation:

The midpoint is the exact halfway point, so all you need to do is find the distance between those two points and apply it again.

First find the x coordinate. The distance from -9 to 2 is 11. So you add 11 to 2, and you get 13, which is your x coordinate.

Then do the same thing with the y coordinate. And you get -6.

Your endpoint is (13,-6)

Answer:

The answer lies in the gradient.

Step-by-step explanation:

The gradient in this equation is -5/8. If any line has the same gradient as the equation above they are parallel because they have the same slant or tilt. Gradient determines if a line is parallel between linear line graphs. If the gradient between two linear line graphs are equal that means that they are parallel.

First identify what is the gradient of a line. The gradient is usually the number that is multiplied with x. In this case (-5/8x), -5/8 is the gradient.

Answer:

it gives you -140 if you multiply all of them

Answer:

-140

Step-by-step explanation:

–2×-7= 14

minus Minus cut so 14 will be Positive no

then, 14×-10=-140

plus minus = Minus

so,

-140 is the answer

Let length be x

ATQ

[tex]\\ \sf\longmapsto 2(L+B)=24[/tex]

[tex]\\ \sf\longmapsto 2(x+2x)=2=[/tex]

[tex]\\ \sf\longmapsto 2(3x)=24[/tex]

[tex]\\ \sf\longmapsto 6x=24[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{24}{6}[/tex]

[tex]\\ \sf\longmapsto x=4[/tex]

Step-by-step explanation:

let the length be X and breadth be 2x

p=2(l+b)

24=2(X+2x)

24=2x+4x

24=6x

24÷6=x

4=X

so,we know that

X=4 and 2x=2 X 4= 8

therefore the value of breadth or width is 8

Answer: d=7.5

Step-by-step explanation: 5.5=−2+d                                                                     d−2+2=5.5+2                                                                                                             d=7.5                  

Answer:

First rewrite the question: d + -2 = 5.5

Step-by-step explanation:

3.5 is your answer.

Answer:

The square root of 2 is between 1 and 2, so radical 2 is about 1.4.

Step-by-step explanation:

You can plot a 1 on the very left and a 2 on the very right of the number line.

Since there is no formal square root of 2, you have to estimate.

It has to be less than 2 because if you multiply 2 * 2 you get 4 and that's too big; we want to get 2.

It also has to be greater than 1 because 1 * 1 = 1 and that's too low.

I would estimate it to be right before the middle line.

Answer:

Answer is 0.67 rounding up

Answer:

X = 23

triangle angles sum = 180

67 + 49 + (3x-5) = 180

3x + 111 = 180

3x = 69

x = 23

The profit function is simply the difference between the revenue function and the cost function. The profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

Given that:

[tex]R(t) = t^2 + 7t + 159[/tex]

[tex]c(t) = t^2 + 131[/tex]

The profit function P(t) is calculated as follows:

[tex]P(t) = R(t) - c(t)[/tex]

So, we have:

[tex]P(t) = t^2 + 7t + 159 - (t^2 + 131)[/tex]

Open brackets

[tex]P(t) = t^2 + 7t + 159 - t^2 - 131[/tex]

Collect like terms

[tex]P(t) = t^2- t^2 + 7t + 159 - 131[/tex]

[tex]P(t) = 7t + 28[/tex]

Hence, the profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

Explanation:

Right-angled triangles have one of their angles to be 90°.

Angles in a triangle is 180°

=>The other two angles will sum up to 90°

Let x represent the other acute angle

2 less than 3 times the size of the other acute angle.

3(x)-2=one angle.

Equating both angles to 90°

=> other acute angle + one angle =90°

=> x+3x-2=90°

=>4x-2=90°

=>4x=90-2

=>4x=88

Divide both sides by 4

x=22°

Other acute angle=22°

One angle= 3(22)-2

=>66-2

=>64°

Proof= 22+64+2+90=180°

Answer:

Number two: x > -9/2, x < 3/2

Number one: x is less than or equal to 3/4, x is greater than or equal to - 13/4

Step-by-step explanation:

Number one:

|4x+5| > 10-2

|4x+5| > 8

4x+5 > 8

-(4x+5) > 8

x > 3/4

x < -13/4

x > 3/4, x < -13/4

(all of these signs are greater than or equal to and less than or equal to)

Number two:

|2x+3| > -6

2x+3 > -6

-(2x+3) > -6

x > -9/2

x < 3/2

x> -9/2, x < 3/2

(all of these signs are correct and not greater than or equal to or less than or equal to)
