Answer:
y = -1/2x -3
Step-by-step explanation:
The line perpendicular to one with a slope of 2 will have a slope that is the negative reciprocal of 2, that is, -1/2. The given point is the y-intercept of the required line, so we can write its equation directly in slope-intercept form:
y = mx + b
where m is the slope (-1/2), and b is the y-intercept (-3). Your line is ...
y = -1/2x -3
Evaluate the expression for x = -2, y = 3, and a = -4
5x-6y-3a
Hey there!
5x - 6y - 3a
= 5(-2) - 6(3) - 3(-4)
= -10 - 18 - 12
= -28 - (-12)
= -28 + 12
= -16
Therefore, your answer is: -16
Good luck on your assignment and enjoy your day!

The area of a square is 676 square root. what is the perimeter of the square?
Answer:
the perimeter of the square is 104
Step-by-step explanation:
to find the perimeter of a square we need to use the formula P = 4a
P is perimeter and a is the side of the square
if a is the side and the formula of Area is A = a^2
that means the side of the square is a = 26 because 26 * 26 = 676
now we take 26 and place it in the a spot of the perimeter formula
P = 4 * 26 (P = 104)
can i get brain if this helps and is correct plz and thxs <(^w^)>
Answer:
It's 104
Step-by-step explanation:
[tex] \sqrt{676 = 26} [/tex]Square perimeter formula : P=4×aP=4×aP=4×26P=104Determine whether the ordered pair is a solution of the linear equation y = 11r - 4 (0 -4)
Hi there!
»»————- ★ ————-««
I believe your answer is:
Yes, it is a solution.
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
I am assuming that 'r' is supposed to be 'x'.
⸻⸻⸻⸻
[tex]y=11r-4\\------------\\\rightarrow -4 = 11(0) - 4\\\\\rightarrow -4 = 0 -4\\\\\rightarrow \boxed{-4=-4}[/tex]
⸻⸻⸻⸻
The ordered pair is a solution. You can also tell that it is a solution because the equation given is in slope-intercept form, and '-4' is in b's spot.
⸻⸻⸻⸻
[tex]y = mx+b[/tex]
⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Factor completely
[tex]3x²+20x-7[/tex]
Please show all workings
Answer:
(x + 7)(3x - 1)Step-by-step explanation:
See the steps below:
3x² + 20x - 7 = 3x² + 21x - x - 7 = 3x(x + 7) - (x + 7) = (x + 7)(3x - 1)First Method: (By splitting the middle term)
We have to find p and q such that p+q = 20 and
pq = 3×(-7) = -21
Let us looks for the pair of factors of -21 such that their sum is 20 and product is -21.
20 = 21 - 1 and -21 = 3(-7)
∴ 3x² + 20x - 7 = 3x² + 21x - 1x - 7
= 3x(x + 7) -1(x + 7)
= (x + 7)(3x - 1)
Second method: (Using the factor theorem)

What is 97 divided by 80257
Original price: $12
Mark-up: 45%
What is the selling price?
Answer:
The selling price is $17.40
Step-by-step explanation:
x = selling price
x = 12 + 0.45(12)
x = 12 + 5.4
x = 17.4
The final selling price is $17.40.
Percentages are percents of a whole. This means that 45% = 0.45. You can use this to your advangage when solving these types of equations.
Answer:
$17.40
Step-by-step explanation
Find what 45% of 12 is.
You can do this by multiplying 0.45 by 12 which is 5.4
Then you just add 5.4 to 12 which gives you 17.4

m^ 2 + m − 90 factorize
Answer:
(m+10)(m-9)
Step-by-step explanation:
To factor this equation we want to find two numbers that multiply to -90 but also add/subtract to 1.
Those two numbers are 10 and -9 (10×-9=-90, 10-9=1)
Answer:
[tex](m-9)(m+10)[/tex]
Step-by-step explanation:
When you are given an expression in this format
[tex]ax^2+bx+c[/tex]
You must find two numbers that add up to b while the product is c.
You do trial and error to figure it out for your equation.
[tex]m^2+m-90[/tex]
Hmm... what two numbers add up to 1 and multiplied together equal -90.
Start off with pairs that can equal 90.
45 2
18 5
9 10
Ok, well 45 * 2 does equal 90 but 45 + 2 = 47and 45 + -2 = 43 but there's no way I can make it equal to 1. Next!
18 * 5 equals 90 but 18 + -5 = 13 and 18 + 5 = 23, I can just tell that there's no way I can make this equal to 1.
9 * 10 equals 90, 9 + 10 = 19 but 9 + -10 = -1. Now, that's interesting, We have -1 but we need 1. All we have to do is flip the order. 10 + -9 = 1. And -9 * 10 = -90, PERFECT!
Now use the two numbers and put it in factored form.
[tex](m-9)(m+10)[/tex]

Find the slope and y-intercept for a line passing through the following two points, then create a slope intercept equation.
(5,3) and (4,5)
Slope=
Y-intercept=
Slope intercept equation=
Answer:
Slope = -2
Y-intercept = 13
y = -2x + 13
Step-by-step explanation:
(5-3)/(4-5) = 2/-1 = -2
3 = -2(5) + b
3 = -10 + b
b = 13
y = -2x + 13
