I needhelp with this math assignment

Answer:

x=5

Step-by-step explanation:

x^2+25-10x = x^2-25

-x^2               -x^2

25-10x = -25

-25        -25

-10x = -50

x=5

lets check

(5-5)^2 = 5^2-25

0^2 = 25-25

0 = 0

Answer:

x = 5

Step-by-step explanation:

(x - 5)^2 = (x - 5) (x - 5) =

x^2 -10x + 25 = x^2 - 25

x^2 - x^2 - 10x + 25 = - 25 (x^2 - x^2 = 0)

- 10x + 25 = - 25

- 10x = - 25 - 25

x = - 50/- 10

x = 5

Answer:

1) Divide the numerator by the denominator to get 0.6

2) Divide the numerator by the denominator to get 0.7

3) Divide the numerator by the denominator to get 0.25

4) Place 55 over 100, since this number is in the hundredths place, and then divide it (55 ÷ 100). Your answer is 11/20 .

5) Place 6 over 10, since this number is in the tenths place, and then divide it

(6 ÷ 10 = 3/5). Next multiply the whole number (10) by the denominator (5) and then add the numerator (3) to get 53. You now have 53/5 which is the improper form, or 10 3/5 which is the mixed number form.

6) Place 856 over 1,000 , since this is in the thousandths place, and then divide it

(856 ÷ 1,000). Your answer is 107/125 .

7) 0.05, 0.5, 4/5

8) 1.3, 1 1/2, 1.85

Answer:

x² - 3x ≤ 54 m²

Step-by-step explanation:

Step-by-step explanation:

and ? what do we need to do with this ?

compress/simplify this ?

if that is true :

(x+3)(x²-3x+9)-(54+x³)

x³ - 3x² + 9x + 3x² - 9x + 27 - 54 - x³ = -27

Answer:

Step-by-step explanation:

20%

Answer:

The correct answer is 20.0% increase.

Step-by-step explanation:

In this situation, you would need to find how to find the percentage of change.

Therefore, you will need to first use subtraction, division and then multiplication to justify your answer.

--

First, find out how much the original number increased by.

[tex]420-350=70[/tex]

Next, divide the 70 with the original number, which is 350.

[tex]7[/tex] ÷ [tex]350=0.2[/tex]

Finally, to turn your decimal into a whole number, multiply by 100.

[tex]0.2[/tex] × [tex]100=20[/tex]

--

Remember to add the percent (%) symbol after receiving your final product.

Step-by-step explanation:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2.

Answer:

695/kph

Step-by-step explanation:

Divide the kilometers (3475) by the number of hours (5)

to get 695

130%

Step-by-step explanation:

(299 - 130)/130 × 100%

= 169/130 × 100%

= 169/13 × 10%

= 13 × 10%

= 130%

Answer:

x+9=18-2x

-x         -x

9=18-3x

-18-18

-9=-3x

-3   -3

3=x

x=3  

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable and solve for x for the question “ x + 9 = 18 + -2x”.

Hope this helps :)

Answer:

Hey, so it's actually pretty simple I'll try my best to explain it properly!

Step-by-step explanation:

So for the first blue circle the line that goes to the middle that's the radius. And to solve the area you need to know the radius. The formula to solve the area is A = [tex]\pi[/tex] [tex]r^{2}[/tex] so what we would do its 3.14 times 6 times 6 or 3.14 times 36 which would give us the area! Now for circumference, the equation for that is C = 2[tex]\pi r^{2}[/tex] which would look like 2 times 3.14 times 6 times 6 or 2 times 3.14 times 36 and that would give you the circumference.

Answer: is this what your looking for

Step-by-step explanation:

Answer: y=4x-5

Step-by-step explanation:

The slope of y=4x+23 is:4 m=4  

The parallel line needs to have the same slope of 4

Solve it using the "point-slope" equation of a line:   y− y1 = 2(x − x1)

substitute or put in the point (2,3):

y − (3) = 4(x − 2)

y - 3 = 4x - 8      

 put it in slope intercept form y = mx + b  

y  = 4x − 5

The answer is I think now sure 33.2

Answer:

slope is -2/3

Step-by-step explanation:

y = mx+b

m = slope

b = y-intercept

given: y = -2/3x

in this case we don't have a b so make it an automatic 0

now we have y = -2/3x +0

slope is m, so our slope is -2/3

Answer:

B

Step-by-step explanation:

DE is the line that has two ticks through it - the same as FG

the next line goes through the hypotenuse and it is EG for the first triangle and GE for the second

the last line goes through the line with one tick: GD and EF; the points G and D are at the ends of the first part of the congruence statement. the points E and F are also at the ends of their congruence statements

thus the answer is B
