Answer:
y-9+7(x-5)
Step-by-step explanation:
y - x1 = m ( x - y1 )
Y1 = 9
x1 = 5
m=slope (in this case 7)
Answer:
[7x-y-26=0]
Step-by-step explanation:
point slope form =
y-y1=m(x-x1)
=
y-9=7(x-5)
=
[7x-y-26=0]
you may want the y-9=7(x-5) as your answer
second part of this is for vertex form
/////// vertex form ///////Use formula y=mx+b where m is slope
y is equal to 9
x is equal to 5
b=?
m=7
9=7*5+b ---> b= -26

simplify the surd 3√ 20 +√ 45
Answer:
9[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
Simplify the radicals
[tex]\sqrt{20}[/tex]
= [tex]\sqrt{4(5)}[/tex]
= [tex]\sqrt{4}[/tex] × [tex]\sqrt{5}[/tex]
= 2[tex]\sqrt{5}[/tex]
[tex]\sqrt{45}[/tex]
= [tex]\sqrt{9(5)}[/tex]
= [tex]\sqrt{9}[/tex] × [tex]\sqrt{5}[/tex]
= 3[tex]\sqrt{5}[/tex]
Then
3[tex]\sqrt{20}[/tex] + [tex]\sqrt{45}[/tex]
= 3(2[tex]\sqrt{5}[/tex] ) + 3[tex]\sqrt{5}[/tex]
= 6[tex]\sqrt{5}[/tex] + 3[tex]\sqrt{5}[/tex]
= 9[tex]\sqrt{5}[/tex]

Step-by-step explanation:
I think of a number, double it, subtract 3,
the result is 7. Evaluate the number that I first thought of.
Answer:
5
Step-by-step explanation:
2x - 3 = 7
this equation can represent the senario because the number (x) is doubles (multiplyed by 2), subtracted by 3 then equal to 7
then you can just solve for x
2x=10
x=5

I am having a family reunion this summer. I have $5,000.00 to spend. I will spend $1575.00 for decorations and entertainment. The cator will charge
$26.00 per person. How many people can attend with the given budget. Write and solve an equation, then state how many people can attend the
reunion.
Answer:
The answer is 131 people
Step-by-step explanation:
I'm not too sure about equations bc its been a min since I've done them but maybeeeee it's 26x - (1,575) = 5,000 something like that LOL
All I know is that you have to subtract 1575 from 5,000 and then you get 3,435 dollars left and you divide that by 26 people and you get 131.731 but of course you can't have a half of person so it stays at 131.
Hopefully that helped lol
if x-y=9,x²+y²=27,then xy=?
Answer:
xy = - 27
Step-by-step explanation:
Note that
(x - y)² = x² - 2xy + y² ← substitute given values, that is
9² = 27 - 2xy
81 = 27 - 2xy ( subtract 27 from both sides )
54 = - 2xy (divide both sides by - 2 )
- 27 = xy

The perimeter of a rectangular court is 224 feet. The length is 4 feet more than the width. Write and solve an equation to find the dimension of the court.
Which is a solution to the equation?
(x - 3)(x - 5) = 35
Ox= -8
O x= -5
O x= 2
O x = 10
Answer:
x=10
Step-by-step explanation:
Let's solve your equation step-by-step.
(x−3)(x−5)=35
Step 1: Simplify both sides of the equation.
x2−8x+15=35
Step 2: Subtract 35 from both sides.
x2−8x+15−35=35−35
x2−8x−20=0
Step 3: Factor left side of equation.
(x+2)(x−10)=0
Step 4: Set factors equal to 0.
x+2=0 or x−10=0
x=−2 or x=10

Find the value of x in the figure below 13x+8 2x+7
Step-by-step explanation:
step 1. (13x + 8) + (2x + 7) = 180 (definition of same side interior angles)
step 2. 15x + 15 = 180 (like terms)
step 3. 15x = 165 (subtract 15 from each side)
step 4. x = 11. (divide both sides by 15)

Given the equation 4(3n-7) = -19, what is the first step you could use to solve for n?
Answer:
3/4
Step-by-step explanation:
4(3n-7)=-19
3n-7=-19/4
3n=-19/4+7
3n=-19/4+28/4
3n=9/4
n=(9/4)/3
n=(9/4)(1/3)
n=9/12
simplify
n=3/4
Answer:
3/4
You would have to divide both sides by 4
Step-by-step explanation:
[tex]\frac{4(3n-7)}{4} =\frac{-19}{4}[/tex] ( divide both sides by 4 )
[tex]3n-7= -\frac{19}{4}[/tex] ( simplify )
[tex]3n-7+7=-\frac{19}{4} +7[/tex] ( add 7 to both sides )
[tex]3n=\frac{9}{4}[/tex] ( simplify )
[tex]\frac{3n}{3} =\frac{\frac{9}{4} }{3}[/tex] ( divide both sides by 3 )
[tex]n=\frac{3}{4}[/tex]

Here is a square inscribed in a circle with radius 1 meter. What is the perimeter of
the square? Explain or show your reasoning
Answer:
[tex]4\sqrt{2}[/tex]
Step-by-step explanation:
distance formula:[tex]\sqrt{\left(x_2-x_1\right)^{2}+\left(y_2-y_1\right)^{2}}[/tex]
set square to be centered on the origin and find the distance between 2 of the connected points
[tex]\sqrt{\left(3-2\right)^{2}+\left(2-1\right)^{2}}[/tex]
= [tex]\sqrt{\left(1\right)^{2}+\left(1\right)^{2}}[/tex]
= [tex]\sqrt{2}[/tex]
multiply by 4 as it is a square and all of its sides are equal
[tex]4\sqrt{2}[/tex]
insert units
[tex]4\sqrt{2}\ \ meters[/tex]
The perimeter of the square is √32.
Given to us
the radius of the circle is 1 meterWhat is the diagonal of the square inscribed in the circle?As we can see in the figure AB is the diagonal of the square and diameter of the circle. therefore,
AB = Diagonal of the square = Diameter of circle = 2 x Radius = 2 meter
We know the diagonal of a square is equal to the product of √2 and the side of the square.
[tex]Diagonal = side \times {\sqrt2}[/tex]
Substitute the value,
[tex]2 = side \times {\sqrt2}\\\\side = \dfrac{2}{\sqrt2}\\\\side ={\sqrt2}[/tex]
What is the perimeter of the square?The perimeter of the square is four times the side of the square.
[tex]Perimeter = 4\times (side)[/tex]
Substitute the value,
[tex]Perimeter = 4\times (\sqrt2)\\\\Perimeter = 4\sqrt2 = \sqrt{2\times 16} = \sqrt{32}[/tex]
Hence, the perimeter of the square is √32.
