Evaluate This Question

Answer:

[tex]y=2x-10[/tex]

Step-by-step explanation:

We know that the line has a slope of 2 and it passes through the point (3, -4).

So, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, let’s substitute 2 for m and (3, -4) for (x₁, y₁). This yields:

[tex]y-(-4)=2(x-3)[/tex]

Solve for y. Distribute the right:

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

Subtract 4 from both sides. Therefore, our equation is:

[tex]y=2x-10[/tex]

Simplest form of expression  6x-12 is 6(x - 2).

An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Expressions are made up of terms.

Given expression

6x-12

Multiplying and dividing with 6

6(x - 2)

Hence, 6(x - 2) is the simplest form of expression 6x-12.

This question is incomplete, the complete question is;

Given that a Historical Demand for a product is;

Month         Demand

January      12

February    11

March        15

April           12

May            16

June           15

Using a weighted moving average with weights of 0.60 for June, 0.30 for May, and 0.10 for April, find the July forecast.

Answer: the July forecast is 15

Step-by-step explanation:

Given that;

Month       Demand          Weights

January      12

February    11

March        15

April           12                     0.10

May            16                     0.30

June           15                     0.60

July             ?                          ?

Formula for calculating weighted moving average is

Ft = w1A_t-1 + w2A_t-2 ............+ wnA_t-n  

w1, w2, wn is the weight assigned to the period t-1, t-2, t-n respevtively

A_t-1, A_t-2, A_t-n is the demand period t-1, t-2, t-n respevtively

and n is the total number prior periods in the forecast.

so we just substitute our values into the equation

Forecast(July)  = (15 × 0.6) + (16 × 0.30) + ( 12 × 0.10)

= 9 + 4.8 + 1.2

= 15

Therefore the July forecast is 15

Answer:

Step-by-step explanation:

if they're equivalent, when you plug in either 10 or 6 for x, they should both equal the same.

x=10, 8(10)+40=120.... 8(10+5)=120. so they equal. also test 6

8(6)+40=88. 8(6+5)=88

they are equivalent since they both equal each other, no matter what you plug in. reason being that the 8(x+5) is the factorized version of 8x+40

Answer:

By putting both values of x in the expression, it can be concluded that both expressions are equivalent.

Step-by-step explanation:

The expressions can be evaluated to be equivalent by putting the values given

The expressions are:

8x+40 and 8(x+5)

Putting x = 6 in both

[tex]8x+40\ and\ 8(x+5)\\8(6)+40\ \ ; \ 8(5+6)\\48+40\ \ \ \ ; \ \ 8(11)\\88\ \ \ \ \ \ \ \ \ \ \ ; \ \ 88[/tex]

The values of both expressions are same on x=6

Now putting x = 10

[tex]8x+40\ and\ 8(x+5)\\8(10)+40\ \ ; \ 8(10+6)\\80+40\ \ \ \ ; \ \ 8(16)\\120\ \ \ \ \ \ \ \ \ ; \ \ 120[/tex]

The values of both expressions are same on x = 10

Hence,

By putting both values of x in the expression, it can be concluded that both expressions are equivalent.

Answer:

Step-by-step explanation:

Remark

If the horizontal lines are parallel, then 2x +  20 = 3x - 10

Equation

2x + 20 = 3x - 10

Add 10 to both sides

2x + 20 + 10 = 3x

Subtract 2x from both sides

30 = x

2x + 20 = 2*30 + 20 = 80

Answer:

x = 30 and both the angles are 80°

__________________________________________________________

In the given figure,

∠(2x + 20) = ∠(3x - 10)             [corresponding angles]

20 = x - 10                                [subtracting 2x from both sides]

x = 30                                      [adding 10 on both sides]

Value of the angles:

the questions required us to find the measure of a certain ∠XAE, but since we cannot see an ∠XAE in the image provided, we will find the measure of both the angles     [let ∠(2x + 20) = ∠1     and     ∠(3x-10) = ∠2]

Measure of ∠1:

We are given that the magnitude of ∠1 is:

∠1 = 2x + 20

since x = 30

∠1 = 2(30) + 20                             [replacing the value of x]

∠1 = 80°

Measure of ∠2:

We are given that the magnitude of ∠2 is:

∠2 = 3x - 10

since x = 30

∠2 = 3(30) - 10                              [replacing the value of x]

∠2 = 80°

Question:

The cost of 12 kg sugar is $240 what will be the cost of 3 kg sugar.

Given:

To find?

Answer :

To find cost of 3kg sugar first we have to find cost of 1 kg sugar.

Now Let's find cost of 3 kg sugar

Cost of 3kg sugar = total no of sugar ×Cost of 1 kg sugar

Cost of 3kg sugar = 3×$20

Cost of 3kg sugar = $60

Answer:

[tex]a = 10[/tex]

Step-by-step explanation:

Given

[tex]Initial\ Velocity\ (u) = 20m/s[/tex]

[tex]Final\ Velocity\ (v) = 60m/s[/tex]

[tex]Time = 4s[/tex]

Required

Determine the acceleration

This question will be answered using the first equation of motion.

[tex]v = u + at[/tex]

Substitute values for v, u and t

[tex]60 = 20 + 4 * a[/tex]

[tex]60 = 20 + 4 a[/tex]

Subtract 20 from both sides

[tex]60 - 20= 20 -20 + 4 a[/tex]

[tex]40= 4 a[/tex]

Divide both sides by 4

[tex]10 = a[/tex]

[tex]a = 10[/tex]

Hence, the acceleration is 10m/s/s

Answer:

I believe that the answers are:

a= 65 degrees

b= 80 degrees

Step-by-step explanation:

Purple 80 and b should be the same so 80 degrees

180 - 80 is 100 which is A so a equals 100-35 whis is 65.

Answer:

a=65°, b=100°

Step-by-step explanation:

Hope the answers help! I got confused at first, but take a last look at line BE. Angle EAF is vertically opposite to this line. This means that angle BAF equals 80°. b=100°. a is just 180-80-35, so a=65°.

Answer:

8 should be multiplied in the parenthesis

Step-by-step explanation:

8(9 + x) = 192

72 + 8x = 192

8x = 120

x = 4

Javier made the mistake while expanding the brackets.

Order of operation means simplify the function , expression etc. in given manner.  

To expand a single bracket multiply each term inside the bracket by the term outside the bracket.

8 (9+x) = 192

8*9 + 8*x = 192

72 + 8x = 192

Now, rearranging the above expression

8x = 192 - 72

8x = 120

x = 120/ 8

x = 5

Hence, Javier made the mistake while expanding the brackets.
