Write an equation in slope-intercept form of the line through point P(-10, 1) with slope -5.

AfilCa [17]

Your equation for number one is 600,788,188/760,507,625 = x/100
After cross multiplying you will get 760,507,625x = 60,078,818,800
Then you will divide by 760,507,625 to isolate the varible to get 78.99 = x.

Your equation in number two is 80/143 = x/100 because when you subtract 143 by 63 you get 80, the amount of males in the room. Then you cross multiply to get, 143x = 8000. Then you would divide both sides by 143 to isolate the varible to get 55%

4. These polygons are similar, but not drawn to scale. Find the value of x.

Dafna11 [192]

Answer

x=10

Step by step explanation:

It is a dilation to you would divide the known sides with each other.

8/2=4

16/4=4

So, you would then multiply 2.5 by 4 which would get you 10

preetty sure this is it, if its wrong then im sorry

Angelina factored (x - 4^8 ) and wrote that it was equal to (x^2 - 4^2)^2(x^2 + 4^2). Use complete sentences to explain how you

nikitadnepr [17]

Given is (x - 4⁸)

Her factors are (x² - 4²)² (x² + 4²)

Let us prove whether her solution is correct or not.

(x² - 4²)² (x² + 4²)
(x⁴ - 4⁴) (x² + 4²) ; Follow PEMDAS rule as well as exponential multiplication rule which tells that when exponents are multiplied, the exponents will be added.

By using FOIL(First, Outside, Inside, Last) Method, we can prove if Angelina's solution is correct. NOTE: Do not disregard the positive or negative.

(x⁴ - 4⁴) (x² + 4²) ; For the First, multiply the first terms. They are underlined.
This gives you a partial answer: x⁶ (Exponential Law of Multiplication is applied)

(x⁴ - 4⁴) (x² + 4²) ; For the Outside, multiply the outside terms. They are underlined. This gives you an additional to the partial answer: x⁶ + 4²x⁴

(x⁴ - 4⁴) (x² + 4²) ; For the Inside, multiply the inside terms. They are underlined. This gives you an additional to the partial answer: x⁶ + 4²x⁴ - 4⁴x²

(x⁴ - 4⁴) (x² + 4²) ; For the Last, multiply the last terms. They are underlined. This will give you an additional to the final answer: x⁶ + 4²x⁴ - 4⁴x² - 16⁶ = 0

Final Answer in complete sentence:
The result of multiplying the factors is x⁶ + 4²x⁴ - 4⁴x² - 16⁶ = 0 and is too far compared to (x - 4⁸) which is already a factor.

After joining two pieces of a picture frame together, a frame maker checks her work by measuring the diagonal (see the illustrat

tigry1 [53]

The diagonal (hypotenuse) is 13 in.

You need to use the Pythagorean Theorem

${a}^{2} + {b}^{2} = {c}^{2}$
then just plug in the numbers and solve for c.

${12}^{2} + {5}^{2} = {c}^{2}$
$\sqrt{169} = c$
13 = c
