Answer:

[tex] - \frac{5}{2} [/tex]

Step-by-step explanation:

4x -10y= 40

Let's rewrite this equation in the slope-intercept form (y= mx +c) so that we can obtain it's slope.

10y= 4x -40

Divide both side by 10:

[tex]y = \frac{2}{5} x - 4[/tex]

The product of the gradients of perpendicular lines is -1.

⅖(gradient of line)= -1

Gradient of perpendicular line

[tex] = - 1 \div \frac{2}{5} [/tex]

[tex] = - 1 \times \frac{5}{2} [/tex]

[tex] = - \frac{5}{2} [/tex]

Answer:

50°F

Step-by-step explanation:

Given the equivalent celcius and Fahrenheit temperature relation :

t℃=(32+1.8t)℉

t = any rational number :

Taking a rational number, t = 10

The Fahrenheit temperature obtained will be :

t°C = 10

t℃=[32+1.8(10)] ℉

10°°C = (32 + 18)°F

The equivalent Fahrenheit temperature = 50°F

Answer:

log_4(256)=4

log_4(1/1024)=-5

log_4(16)=2

log_4(1/256)=-4

Step-by-step explanation:

We want to write a number, x, such that

Log_4(y)=x.

In exponential form that is 4^x=y.

So first number is x=4.

4^4=256 which means log_4(256) is 4 as a logarithm with base 4.

The second number is x=-5.

4^-5=1/4^5=1/1024 which means log_4(1/1024) is -5 as a logarithm with base 4.

The third number is x=2.

4^2=16 so log_4(16) is 2 as a logarithm with base 4.

The fourth number is x=-4.

Since 4^4=256 then 4^-4=1/256 which means -4 as a logarithm with base 4 is log_4(1/256).

The logarithmic expressions are: [tex]\log_4(256) = 4[/tex], [tex]\log_4({4^{-5}}) = -5[/tex], [tex]\log_4({16) = 2[/tex] and [tex]\log_4({4^{-4}) = -4[/tex]

A number x written in logarithm form is represented as:

[tex]\log_b(y)=x.[/tex]

Where:

[tex]b^x=y[/tex]

Given that the base is 4, the equations become:

[tex]\log_4(y) = x[/tex]

[tex]4^x = y[/tex]

For number 4, we have:

[tex]y = 4^4[/tex]

[tex]y = 256[/tex]

This gives

[tex]\log_4(256) = 4[/tex]

For number -5, we have:

[tex]y = 4^{-5}[/tex]

This gives

[tex]\log_4({4^{-5}}) = -5[/tex]

For number 2, we have:

[tex]y = 4^{2}[/tex]

[tex]y =16[/tex]

This gives

[tex]\log_4({16) = 2[/tex]

For number -4, we have:

[tex]y = 4^{-4}[/tex]

This gives

[tex]\log_4({4^{-4}) = -4[/tex]

Hence, the logarithmic expressions are: [tex]\log_4(256) = 4[/tex], [tex]\log_4({4^{-5}}) = -5[/tex], [tex]\log_4({16) = 2[/tex] and [tex]\log_4({4^{-4}) = -4[/tex]

Answer:

See Explanation

Step-by-step explanation:

Incomplete question, as the number line is not attached. However, the solution is as follows:

Let y be the absolute value of -1/2 So:

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

The absolute sign removes all negation. So:

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

This means that the point at the label [tex]\frac{1}{2}[/tex] or [tex]0.5[/tex] is the solution to the question.

Take for instance, the attached image has point Q at [tex]\frac{1}{2}[/tex].

Hence, Q is the absolute value of -1/2

Answer:

P = (25.6g - 31.4)

Step-by-step explanation:

Given that,

The width of a rectangle = (8.1g−6.5) cm

The length of a rectangle, = (4.7g−9.2)

We know that,

The perimeter of a rectangle is given by :

P = 2(l+b)

Substitute all the values,

P = 2(8.1g−6.5+4.7g−9.2)

= 2(12.8g-15.7)

= 25.6g - 31.4

So, the perimeter of the rectangle is equal to (25.6g - 31.4).

Answer:

x = 70.53 degrees

Step-by-step explanation:

equation:

cos-1 = [tex]\frac{adjacent}{hypotenuse}[/tex]

⇒ cos-1 x = [tex]\frac{4}{12}[/tex]

⇒ cos-1 x = 0.33

⇒ x = 70.528

round to the nearest tenth:

⇒ 70.53

Here is your answer!

= x + (x + 2) + 3(x + 2) = T

= (3x + 2) + (3x +6) = T

= 3x + 3x + 2 + 6 = T

= 6x + 8 = T

T = 5x + 8 is the formula for T expressed in terms of x.

A relationship between two expressions or values that is not equal to one another is referred to as "inequality" in mathematics. Therefore, an imbalance leads to inequity.

Given, Simon has x sweets. Yuen has 2 more sweets than Simon. Giulia has 3 times as many sweets as Yuen. Simon, Yuen, and Giulia have a total of T sweets.

From the given Data,

Thus, in Total sweets, Simon has = x

Total sweets Yuen have = x + 2

Total sweets Giulia have = 3*(x + 2 )

Since the total sweets all three have is T

Hence, T = x + x +2 + 3(x + 2)

T = x + x + 2 + 3x + 6

T = 5x + 8

Therefore, The formula for T in terms of x is T = 5x + 8
