Use the distributive property to rewrite this expression.
4(y + 6)

Answer:

A) 1:2

B) 3:5

C) 5:4

D) 17:5

Step-by-step explanation:

Step 1) Convert the decimal number to a fraction

Step 2) Multiply the numerator and denominator by 10 to eliminate the decimal point.

Step 3) Simplify the fraction in the previous step by dividing the numerator and the denominator by the greatest common factor (GCF)

Step 4) Convert the fraction in the previous step to a ratio by replacing the divider line with a colon

Heres an example. I'll do the last one.

3.4 = 3.4/1

(3.4 x10) /(1 x 10)= 34/10

34 /2 = 17

10/2  = 5

17/5 = 17:5

Step-by-step explanation:

that is totally easy.

in the slope intercept form of a line equation the factor of x is always the slope.

in general

y = ax + b

a = the slope.

so, in our case here

y = 5x - 7

5 is the slope.

and -7 is the y intercept (at what point does the line intercept the y-axis; that is the y value when x = 0).

let'sAnswer:

P ≈ 102.83 cm

Step-by-step explanation:

The window is practically a semi-circle. The formula for the perimeter of a semi-circle is πr + d.

*Remember that d (diameter) = 2 · r (radius)

Let's plug in everything that we know into the formula!

r = 20

d = 2(20) → 40

π(20) + 40 = 102.8318531

Now lets round the answer to the hundredths place.

102.8318531 → 102.83

Answer:

62.83 (estimate)

Step-by-step explanation:

The equation for the perimeter of a circle (also called circumference) is 2 times pi times the radius, or pi times the diameter. Since the window is a semi-circle, you divide the result by two.

[tex]2\pi r\\2(20)\pi = 40 \pi\\40\pi= 125.6\\125.663706144/2=62.83[/tex]

Answer:

x<=-4 or -2<=x<=2 or x>=4

Step-by-step explanation:

First, you have to get the formula in its standard form,

x^4 - 18x^2 + 64 >= 0

Next, you factorise the expression as you would any trinomial. The fact that the degree of the inequality is 4 instead of 2 just adds an extra step,

(x^2 - 16)(x^2 - 4) >= 0

Get the zeroes/critical values of the equation by equating either bracket to zero.

x^2 - 16 = 0  and  x^2 - 4 = 0

x^2 = 16                x^2 = 4

Since both values are positive, both answers are valid as squares of x. The aforementioned extra step is just square rooting these values. Remember: This means that both a positive and negative answer will arise from both equations.

x = 4 or x = -4 or x = 2 or x = -2

Now you have to show these values on a number line.

 -4     -2       2       4

_|____|____|____|_

These are the critical values of the inequality, i.e. those values that make it equal zero (zeroes). Now to solve the inequality you need to substitute a value larger than 4 (called x big positive) and then a value between 2 and 4, between -2 and 2... until you sub a value less than -4 into the factorised expression. The point of this is to get the SIGN of the answer. As a rule, since no factors repeat themselves, after calculating x big positive you can simply alternate the signs going left. Try it out yourself!

+ -4 -  -2  +   2   -   4  +

_|____|____|____|_

Since we're looking for values greater than or equal to zero, all critical values as well as "plus signs" will form part of the answer, namely:

x<=-4 or -2<=x<=2 or x>=4

P.S. If you prefer, you could also factorise each bracket further as both of them were DOTS brackets and you would have ended up with the same critical values.

Answer:

The original temperature was -18°F

Step-by-step explanation:

x°F + 24°F = 6°F

or, x°F = 6°F - 24°F

so, x°F = -18°F

Step-by-step explanation:

Multiply $13.50 by 150 then subtract the shipping fee do it on the other answer and you will get your final answer which is 1,825

Answer:

Company A: $1,825

Company B: $1,805

Step-by-step explanation:

Company A will end up giving you the most

1.) 13.50 (payment for 1 lb.) x 150 (# of lbs.) is $2,025

2.) Subtract the $200 shipping fee to get $1,825

Company B is next

1.) 13.20 (payment for 1 lb.) x 150 (# of lbs.) is $1,980

2.) Subtract the $ 175 shipping fee from the total to get $1,805

Answer:

D. -10, 10

Step-by-step explanation:

Instead of inserting values into x to solve, let's isolate x.

In order to do this, we must take the square root of both sides.

[tex]\sqrt{x^{2} } =\sqrt{100}[/tex]

[tex]x=\sqrt{100}[/tex]

To find the square root of 100, we must figure out what = 100 when multiplied by itself. Reminder, it can be both a positive or a negative square root, as positive times positive is a positive, and negative times negative is a positive.

The square root of 100 is -10 or 10, as 10 x 10 or -10 x -10 = 100.

Hope this helps! :)

Answer:

x=2.1

Step-by-step explanation:

collect like terms 2.4x+5.8x=8.2x

move the terms to the left side and change its sign to -8.2x

move the constant(-3.28) to the right and change its sign to 3.28

equation should now be 9x-8.2x=-1.6+3.28

next you're going to do 9x-8.2x=0.8x

then -1.6+3.28=1.68

divide both sides of the equation by 0.8

x=2.1 is your final answer
