Answer:

1.71

Step-by-step explanation:

got it right on my test

The required value of x for the given equation is about 1.71.

Important information:

Divide both sides by 10.

[tex](1.5)^{3x}=\dfrac{80}{10}[/tex]

[tex](1.5)^{3x}=8[/tex]

Taking log on both sides, we get

[tex]\log (1.5)^{3x}=\log 2^3[/tex]

[tex]3x\log (1.5)=3\log 2[/tex]

Divide both sides by 3log(1.5).

[tex]x=\dfrac{3\log 2}{3\log 1.5}[/tex]

[tex]x=\dfrac{\log 2}{\log 1.5}[/tex]

[tex]x\approx 1.71[/tex]

Therefore, the required value of x for the given equation is about 1.71.

1x+7

Step-by-step explanation:

7x+5-6x+2

7x-6x =1x

5+2=7

1x+7

Answer:

1x + 7

Step-by-step explanation:

hey there!first, we put the x numbers on one and the numbers without the x on one side that will look like 7x-6x + 5 + 2 then we slove them that will look like 1x +7 now we add them but we cant not add them because one number is with x and the other number is not with x. if we can not slove we can write them as 1x + 7

Answer:

26

Step-by-step explanation:

h=21+5

h=26

The value of h will be 26, when p =7.

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e. a and b respectively, are not equal to zero.

The method  in which, the value of one variable from one equation is substituted in the other equation. So that, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved. This method is called substitution method.

According to the given question we have

A linear equation in two variable

h = 3p + 5

So, the value of h when p = 7

Substitute, p = 7  in h = 3p + 5

⇒ h = (3 × 7) + 5

⇒ h = 21 + 5

⇒ h = 26

Hence, the value of h will be 26, when p =7.

The equation as a single logarithm is:

[tex]log[(x^2 - 16)/(x + 4)].[/tex]

Option C is the correct answer.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Using the logarithmic identity,

log a - log b = log (a/b)

We can simplify the given expression as:

[tex]=log(x^2 - 16) - log(x + 4) \\= log[(x^2 - 16)/(x + 4)][/tex]

Answer: (3,4)

(X,Y) (X1- Y1)+ (X2- Y2)

The coordinate of point Q is (3,4).

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.

Coordinate point Q can be given by interception formula that state

Coordinate a point with intercept m: n  and bounded by coordinate (x₁, y₁) and (x₂, y₂).

x = [m(x₂) + n(x₁)]/(m + n)

And,

y = [m(y₂) + n(y₁)]/(m + n)

So,

x = [5(5) + 2(-2)]/(5 + 2)

x = 3

Similarly

y = [5(8) + 2(-6)]/(5 + 2)

y = 4

Hence "The coordinate of point Q is (3,4)".

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

Multiplying an integer by 0.01 is the same as Dividing such as :

0.01 = 10^-2

100= 10

For instance :

A number, n = 5 is multiplied by 10^-2

5 * 0.01 = 0.05

Thus, divide the number, n by 100;

5 / 100 = 0.05

Hence, the proof.
