Consider the equation below.
-2(Bx - 5) = 16
The value of x in terms of b is:________
The value of x when b is 3 is:________

Answer with explanation:

Consider two linear equation in two variable,

ax + by =c

p x +q y=r

The equations have an infinite number of solutions , means the two lines are Coincident, when it follows the following law

[tex]\frac{a}{p}= \frac{b}{q}= \frac{c}{r}[/tex]

                                      --------------------------------------(1)

Now, equation of two lines are

1. y= 6 x -b

→6 x -y -b=0

2. -3 x +y= -3

⇒-3 x+y+3=0

By the above law,that is law 1, the two lines will be coincident

[tex]\frac{6}{-3}=\frac{-1}{1}= \frac{-b}{3}\\\\2=1= \frac{b}{3}[/tex]

Which is not possible that is ,2≠1.

→→→Hence the two lines can never be coincident for any value of b.

Answer:

$12

Step-by-step explanation:

30 % × $40 = 30 ÷ 100 × 40 = $12

The value of the Percentage 30% of $40 is: $12

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

Percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%".

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. It is given by:

Percentage = (value / total value) * 100%

Thus:

30% of $40 is calculated as:

30/100 * 40

= 1200/100

= $12

Answer:

14 numbers.

Step-by-step explanation:

Since -4 is in the negatives, we would go up on the number line until we reached positive 10. Which would therefore equal, 14.

Answer:

14 units

Step-by-step explanation:

We have to take the absolute value of the measure in both directions, that is

| 10 - (- 4) | = | 10 + 4 | = | 14 | = 14

| - 4 - 10 | = | - 14 | = 14

step 1

Exchange x for y and y for x

[tex]2(y-2)^{2}=8(7+x)[/tex]

step 2

isolate the variable y

[tex](y-2)^{2}=4(7+x)[/tex]

take the square root both sides

[tex]y-2=(+/-)\sqrt{4(7+x)}[/tex]

[tex]y=2(+/-)\sqrt{4(7+x)}[/tex]

step 3

Let

[tex]f^{-1}(x)=y[/tex]

Step-by-step explanation:

Answer:

x = 42/31, y = -37/62

Step-by-step explanation:

5x + 8y =2

4x -6y =9

Multiply the first equation by 4

4(5x + 8y) =2*4

20x +32y = 8

Multiply this equation by -5

-5(4x -6y) =9*-5

-20x +30y = -45

Add them together

20x +32y = 8

-20x +30y = -45

-----------------------------

62y = -37

Divide by 62

62y/62 = -37/62

Multiply the first equation by 3

3(5x + 8y) =2*3

15x +24y =6

And the second equation by 4

4(4x -6y) =9*4

16x -24y = 36

Add them together

15x +24y =6

16x -24y = 36

-----------------

31x = 42

Divide by 31

31x/31 = 42/31

x = 42/31

Using Sine Rule for Congruence of Triangles

    [tex]\Rightarrow\frac{a}{\ SinA}=\frac{b}{\ Sin B}=\frac{c}{\ Sin C}\\\\\Rightarrow\frac{15}{\ Sin29^{\circ}}=\frac{20}{\ Sin B}\\\\\Rightarrow\frac{15}{0.49}=\frac{20}{\ Sin B}\\\\\Rightarrow \ SinB=\frac{20 \times 0.49}{15}\\\\\Rightarrow \ SinB=\frac{9.8}{15}\\\\\Rightarrow \ SinB=0.65\\\\B=41^{\circ}[/tex]

Using Angle Sum Property of Triangle

⇒∠A+∠B+∠C=180°

To do synthetic division, you first need to get the constant of the divisor and change the sign.

Then list the coefficients of the dividend.

Drop the first coefficient.

Multiply it by the divisor, and write the answer under the next coefficient and add. Repeat till the end.

The answer should be one degree less, the original polynomial.

For this case we must build a quotient such that when multiplied by the divisor, it eliminates the terms of the dividend until it reaches the remainder.

According to the figure we have that the quotient is:

[tex]r ^ 2 + 9r + 6[/tex]

Answer:

Answer:

100

Step-by-step explanation:

550=L+R

2/9=L/R

=========

Solve the second for L:   2R/9=L

Plug this into the first:  550=2R/9 +R

(2/9+1=11/9)  So          :   550=11R/9

Now multiply both sides by 9/11:   550(9)/11=R

R=50(9)=450

L=550-R=550-450=100

There are 100 lefties

The number of left-handed students in the school is 100, calculated by dividing the total student population by the sum of the ratio parts and then multiplying by the number of parts for lefties.

To calculate the number of left-handed students in a school with 550 students and a ratio of lefties to righties of 2:9, you first add the parts of the ratio together (2 + 9 = 11 parts). Knowing that 11 parts represent all students, 1 part is equal to 550 students divided by 11, which is 50 students. Because there are 2 parts for lefties, you multiply 50 students by 2 parts to find out that there are 100 left-handed students in the school.

Answer:

Average = -1°C

Step-by-step explanation:

The data recorded is;

6, -7, -5, 5, -8, 3 (in °C)

Average = [tex]\frac{6 - 7 - 5 + 5 - 8 + 3}{6}[/tex] = -1°C

Answer:

Average temperature listed will be (-1).

Step-by-step explanation:

As we know average of any given set of numbers is = [tex]\frac{\text{Sum of all the numbers}}{\text{Total numbers }}[/tex]

Now the given set of temperatures is 6, -7, -5, 5, -8, 3

Now Sum of all numbers = 6 + (-7) + (-5) + 5 + (-8) + 3

= (-6)

Total numbers = 6

Now average temperature will be = [tex]\frac{-6}{6}=(-1)[/tex]

Therefore, average temperature listed will be (-1).

Answer:

[tex]\large\boxed{3x-4y=-48}[/tex]

Step-by-step explanation:

The standard form of an equation of a line

[tex]Ax+By=C[/tex]

We have the eqution in the point-slope form:

[tex]y-4=\dfrac{3}{4}(x+8)[/tex]

Convert it to the standard form:

[tex]y-4=\dfrac{3}{4}(x+8)[/tex]           multiply both sides by 4

[tex]4y-16=3(x+8)[/tex]           use the distributive property

[tex]4y-16=3x+32[/tex]          add 16 to both sides

[tex]4y=3x+48[/tex]           subtract 3x from both sides

[tex]-3x+4y=48[/tex]           change the signs

[tex]3x-4y=-48[/tex]

Answer:

First option.

Step-by-step explanation:

In this case you need to remember that an angle formed by two intersecting chords is equal to the sum of the intercepted arcs divided by 2. This is:

[tex]Angle\ formed\ by\ two\ intersecting\ chords=\frac{1}{2}(Sum\ of\ intercepted\ arcs)[/tex]

You can identify in the figure that the angle ∠1 is an angle formed by two intersecting chords. Therefore, since the intercepted arcs are SP and QR, you can say the following:

[tex]m\angle 1=\frac{1}2}(mSP+mQR)[/tex]

You can observe that this matches with the first option.

Answer:The age of daughter is 12 years  and age of son is 24 years

Step-by-step explanation:

Given :

Present age of father = 52 years

Let the present age of daughter be x

So according to the question son's age is twice that of daughter's

So present age of son =2x

Now after 4 years the sum of their ages = 100

i.e. x+4 + 2x+4 + 52 +4 =100

3x+ 64 = 100

Subtracting both sides by 64 we get

3x + 64 - 64=100 -64

3x = 36

Dividing LHS and RHS by 3 we get

x=12

i.e. Present age of daughter  = x = 12 years

Present age of son = 2x = 2× 12= 24 years

Answer:

50 degrees

Step-by-step explanation:

As the kite is triangular, the sum of all angles will be 180 degrees.

Let x be the first angle.

Then according to the statement second angle is four times as large as the first, second angle will be:

4x

And according to the statement, the third angle is 55 degrees ° more than the sum of the other two angles, third angle will be:

x+4x+55

So,

x+4x+x+4x+55=180

10x+55=180

10x= 180-55

10x=125

x=125/10

x=12.5 degrees

So first angle is 12.5 degrees.

Second angle = 4(12.5)

=50 degrees

Third angle = x+4x+55

= 12.5+50+55

= 117.5 degrees

To check if the sum of angles is 180 degrees

= 12.5+117.5+50 = 180

Hence, second angle is 50 degrees ..
