To simplify 8.3 − 4

( 6.1 +

) , which operation must be performed first?

Answer:

Step-by-step explanation:

The y intercept, also known as 'c' in the formula y = mx + c acts as the coordinate for y when x = 0 [E.g. (0, 24) which c = 24]

Question 1 =  y = -5x + 50

On the graph, c = 50 [ y = mx + 50 ]

30 - 15 = 15

7 - 4 = 3

15/3 = 5 (for the gradient, or 'm', which you may use the formula 'rise/run' on the line shown) [ y = 5x + 50 ]

ALTHOUGH, in question one, the line has a Negative Correlation, it slants downwards on the slope, so the gradient will be negative : y = -5x + 50

If x = 9, y = (9 x -5) + 50, = -5

y = -5

Question 2 =  y = 2.5x + 5

c = 5

m = 5/2 = 2.5

y = 2.5x + 5

when y = 30 > x = 10

30 = 2.5x + 5

30 - 5 = 25

25 = 2.5x

x = 25/2.5

x = 10

Question 3 = y = -10x + 50

c = 50

m = (30 - 20) / 1 = 10

y = -10x + 50

when x = 4 > y = (-10 x 4) + 50

y = -40 + 50

y = 10

Answer:

x=10.5

Step-by-step explanation:

[tex]\frac{x}{6} =\frac{7}{4} \\x=\frac{7}{4} \times 6\\=\frac{21}{2} \\=10.5[/tex]

Answer:

You got it! B. x ≤ -7 or x ≥ 2

Step-by-step explanation:

In inequalities, a filled dot means "also including," so the value at which the filled dot is placed is also included in the inequality (hence the "or equal to"). In this case, both red dots (at -7 and 2) are filled, so both values are included in the inequality.

The red portions are part of the inequality. Looking at the arrow going from -7 and pointing to the left, we can tell that that value and the ones smaller than -7* are included, so it would be x ≤ -7.

Looking at the arrow pointing from 2 to the right, it includes 2 and all the numbers to the right of it, so the inequality would be x ≥ 2.

So, the final answer is B. x ≤ -7 or x ≥ 2.

*the value of negative numbers decreases as the numbers themselves increase (-5 is larger than - 36, for example).

Answer:

a+b=2ab

b+c=2bc

c+a=2ca

Answer:

Step-by-step explanation:

132-5 therefore the height from the eyes to the window is 127

100 feet away from the base of the tower  

This forms two legs of a triangle

trying to find the degrees of this triangle.

Since its the two legs, you can use tanx which = to opposite side/adjacent side

Therefore, it is tanx = 127/100

But you are looking for x so arctan(1.27)

Must use calculator to find x

Hope this answer helps you :)

Answer:

[tex](a)\ x = 3y - 2[/tex]

[tex](b)\ y = -3x - 2[/tex]

[tex](e)\ 3y - x = -2[/tex]

Step-by-step explanation:

Given

[tex]y =3x -2[/tex]

Required

Equations that can create consistent and independent systems

For a pair of equation to have consistent and independent systems, the equations must have different slopes.

An equation of the form [tex]y = mx + c[/tex] has m has its slope.

In [tex]y =3x -2[/tex]

[tex]m = 3[/tex] --- slope

Considering the options

[tex](a)\ x = 3y - 2[/tex]

Make y the subject

[tex]x = 3y - 2[/tex]

[tex]3y = x+2[/tex]

Divide by 3

[tex]y = \frac{1}{3}x+\frac{2}{3}[/tex]

The slope is:

[tex]m_1 = \frac{1}{3}[/tex]

Hence, (a) can make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](b)\ y = -3x - 2[/tex]

The slope is:

[tex]m= -3[/tex]

Hence, (b) can make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](c)\ y = 3x + 2[/tex]

The slope is:

[tex]m=3[/tex]

Hence, (c) cannot make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](d)\ 6x - 2y = 4[/tex]

Make y the subject

[tex]2y = 6x -4[/tex]

Divide by 2

[tex]y = 3x -2[/tex]

The slope is

[tex]m =3[/tex]

Hence, (d) cannot make a consistent and independent system with [tex]y =3x -2[/tex]

[tex](e)\ 3y - x = -2[/tex]

Make y the subject

[tex]3y = x -2[/tex]

Divide by 3

[tex]y = \frac{1}{3}x -\frac{2}{3}[/tex]

The slope is:

[tex]m = \frac{1}{3}[/tex]

Hence, (e) can make a consistent and independent system with [tex]y =3x -2[/tex]

The slope of the function showing by table is,

⇒ m = - 6

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The table represents a linear function.

Let Two points on the line are (- 2, 8) and (- 1, 2).

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (2 - 8) / (-1 - (-2))

m = - 6 / 1

m = - 6

Thus, The slope of the function showing by table is,

⇒ m = - 6

Answer:

117 centimeters

Step-by-step explanation:

Since the longest pieces is 72 centimeters and it’s ratio is 8, that means the individual unit of the ratio is 9 (72/8=9). You can multiply each part of the ratio by 9

2x9=18

3x9=27

We already know the third part of the ratio is 72. Add all of it together to get the original length.

18+27+72=117 cm

Couldn't really understnd what you wrote but I'll assume it's the standard deviation of a fair, 7-sided die

The standard deviation is just the square root of the variance (which is just the second moment minus the first moment squared)

The first moment (AKA the average is..)

[tex]\frac{1+2+3+4+5+6+7}{7}=4[/tex]

The second moment is..

[tex]\frac{1^2+2^2+3^2+4^2+5^2+6^2+7^2}{7}=20[/tex]

[tex]\sqrt{20-4^2}=2[/tex]

Answer:

The mass of the object will be "25 kg".

Step-by-step explanation:

Given that,

Mass,

m = 15 kg

Acceleration,

a = 5 m/s²

Now,

The force will be:

⇒ [tex]F = ma[/tex]

       [tex]=15\times 5[/tex]

       [tex]=75 \ N[/tex]

When, acceleration (a) = 3 m/s²

⇒ [tex]F = ma[/tex]

or,

⇒ [tex]m=\frac{F}{a}[/tex]

        [tex]=\frac{75}{3}[/tex]

        [tex]=25 \ kg[/tex]
