If x=2, y=5, z=3, find the value of:

Answer:

18

Step-by-step explanation:

Let the required number be x.

write the expression for the difference of the number and 4.

=> x - 4

the question equates 5 times the difference with some other terms, so find the equation for 5 times the difference.

=> 5( x - 4)

The equation in Step 2 is said to be equal to "two less than four times the number".

Find the expression for four times the number

=> 4x

Find the expression for two less than 4x.

=> 4x - 2

Equate the terms that it says are equal:

=> 5(x - 4) = 4x - 2

distributing 5 within the parenthesis:

=> 5x - 20 = 4x - 2

taking like terms on one side:

=> 5x - 4x = 20 - 2

=> x = 18

and x was the required number, so the answer Is 18.

Considering that angles A and C are equal, and the sum of the internal angles of a triangle is 180º, we have that:

The measure of angle A is of: 48º.

The measure of angle B is of: 84º.

The measure of angle C is of: 48º.

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

[tex]6(x - 3) = 4(x + 1)[/tex]

[tex]6x - 18 = 4x + 4[/tex]

[tex]2x = 22[/tex]

[tex]x = \frac{22}{2}[/tex]

[tex]x = 11[/tex]

[tex]6(11 - 3) = 6(8) = 48[/tex]

The measure of angle A is of: 48º.

The measure of angle C is of: 48º.

The sum of the internal angles of a triangle is of 180º, and this is used to find the measure of angle B.

[tex]mA + mB + mC = 180[/tex]

[tex]2(48) + mB = 180[/tex]

[tex]mB = 84[/tex]

The measure of angle B is of: 84º.

Answer:

X=7

Step-by-step explanation:

These are supplementary angles. So they measure to 180º. 180º-95º=85º. 85º-10= 84º. 84º÷12x= 7.

Answer:

12x+1°+95°=180° (int angles)

12x+96°=180°

12x=180°-96°

=84°

Answer:

[tex]5^{1/6} =2x[/tex]

Step-by-step explanation:

Log and exponential forms are inverses. Additionally, the information from one can be used to write in it another form. In a log equation, there are three parts. The formula is [tex]log_{b}(x)=y[/tex]. The formula for exponential equations is [tex]b^y=x[/tex]. This means to find this equation in exponential form write 5 as the base, 1/6 as the power, and 2x as the other side of the equation. This looks like, [tex]5^{1/6} =2x[/tex].

Answer:

y = 5x + 5

Step-by-step explanation:

the slope to be parallel y = 5x + 7 must still be 5. To make the line pass through T, the given point, you plug (-2, -5) into the y= mx + b formula. This becomes( -5 )= 5 (-2) + B, and you solve for b. In this equation, b = 5.

Find the slope of the perpendicular line

When two lines are perpendicular, the product of their slopes is -1. This means that the slopes are negative-reciprocals of each other.

            ⇒  if the slope of one of the lines =  - 6

                 then the slope of the perpendicular line (m) = ¹/₆

Determine the equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                              ⇒  y - 20 =  ¹/₆ (x - (-12))

                               ∴  y - 20 = ¹/₆ (x + 12)

We can also write the equation in the slope-intercept form (y=mx+c) like the equation in the question by making y the subject of the equation and expanding the bracket to simplify:

                          since   y - 20 = ¹/₆ (x + 12)

                                      y - 20 =  ¹/₆x + 2

                                              y =  ¹/₆x + 22

∴ the slope-intercept equation of the perpendicular line is y =  ¹/₆ x + 22.

To test my answer, I have included a Desmos Graph that I graphed using the information provided in the question and my answer.

subtract 5 from both sides -

5x - 7 = -10x + 8

-5 -5

-7 = -15x + 8

subtract 8 from both sides -

-7 = -15x + 8

-8 -8

-15 = -15x

now divide both sides by -15 -

-15/-15 = -15x/-15

The answer: x = 1

(x alone also equals 1)

The answer to whether Dr. Reyes can make a causal inference from the study is;

No, she can't make a casual inference from the study because she met only one of the three criteria's for causality.

Now, the three conditions are;

1) Covariation; This condition means that the causal variable must have to vary with with the variable it is assumed to cause in a systematic manner.

2) Temporal precedence; Thus condition simply means that cause must precede effect. In summary it denotes that the variable that has the causal effect must come before the effect that it is meant to cause.

3) Control for extraneous variables; This condition means that results of an experiment or research must not be due to factors outside of the experiment/research

     Now, in our question, he fulfilled the covariation condition because the

result of the research is tied to the responses from the sample students.

However, she did not fulfill the temporal precedence because the cause of

their moods did not precede the effects in his research.

Also, she did not fulfill the condition of control of extraneous variables

because other factors outside of the research itself may have affected their

moods.
