A line crosses through the point (3,10) and another point can be found on the line by going right 2 and down 7. find slope and y intercept
Answer:
y = [tex]\frac{-7x}{2}+\frac{41}{2}[/tex]
Step-by-step explanation:
We are given the point (3, 10).
The second point is 2 on the x-axis and -7 on the y-axis. So our second point is: (3 + 2, 10 - 7) which is (5, 3).
Our formula for slope is m = [tex]\frac{rise}{run}[/tex] = [tex]\frac{y2-y1}{x2-x1}[/tex]
So, our equation would be [tex]\frac{3-10}{5-3}[/tex] = [tex]\frac{-7}{2}[/tex]
Using the standard formula of a line, y = mx + b, we can substitute for the slope, m.
y = [tex]\frac{-7x}{2}[/tex] + b
Now, we can substitute a point on the line to determine the y-intercept:
Using the point (3, 10),
10 = [tex]\frac{-7(3)}{2}[/tex] + b
b = 10 + [tex]\frac{21}{2}[/tex]
b = [tex]\frac{41}{2}[/tex]
So our full equation is: y = [tex]\frac{-7x}{2}+\frac{41}{2}[/tex]

Alice drew a rectangle with a perimeter of 30 cm and an area of 56 cm2. Which dimensions match Alice's rectangle?
Answer:
The dimensions that match Alice's rectangle are 7 cm and 8 cm.
Step-by-step explanation:
The perimeter of the rectangle is given by:
[tex] P = 2(a + b) = 30 cm [/tex] (1)
Where a and b are the sides of the rectangle
Also, the area of the rectangle is:
[tex] A = a\times b = 56 cm^{2} [/tex] (2)
By solving equation (1) for a, we have:
[tex] a = 15 cm - b [/tex] (3)
Now, by entering equation (3) into (2) we can find one side of the rectangle:
[tex] 56 cm^{2} = (15 cm - b)\times b [/tex]
[tex] b^{2} - 15b + 56 = 0 [/tex]
Solving the above quadratic equation we have:
b₁ = 7 cm and b₂ = 8 cm
Now, the other side of the rectangle can be calculated with equation (3):
[tex] a = 15 cm - b_{1} = 15 - 7 cm = 8 cm [/tex]
or
[tex] a = 15 cm - b_{2} = 15 - 8 cm = 7 cm [/tex]
Taking the first solution (b₁) or the second (b₂), we find that the dimensions that match Alice's rectangle are 7 cm and 8 cm.
Therefore, the dimensions that match Alice's rectangle are 7 cm and 8 cm.
I hope it helps you!
n is an even number. the smallest even number succeeding is
options:
n+2
n+3
n+4
n+1
Answer:
n+2 ...................... As addition of two even number make even and addition of one even and one odd makes odd so we can add 3 and 1 as it will result in odd .
Given f(x) = x + 1 and g(x) = 3x – 5,
what are
the restrictions on the domain when f(x)/g(x)
Answer:
There will be an asymptote at [tex]x=\frac{5}{3}[/tex], meaning the domain is restricted from (-∞, [tex]\frac{5}{3}[/tex])U([tex]\frac{5}{3}[/tex], ∞).
Step-by-step explanation:
When finding domain restrictions for an equation that has a fraction, take the denominator and set it equal to 0. Then, solve for x:
[tex]3x-5=0[/tex]
[tex]3x=5[/tex]
[tex]x=\frac{5}{3}[/tex]
Then we can determine that there's an asymptote at [tex]x=\frac{5}{3}[/tex] but that is the only restriction.

6(x+8.5)=123
(equation)
Answer:
12
Step-by-step explanation:
6(x+8.5)=123
=> 6x + 51 = 123
=> 6x = 123 - 51
=> 6x = 72
[tex] = > x = \frac{72}{6} [/tex]
=> x = 12 (Ans)
Is x = 1 the solution to 3(x + 3) = 8 - 2x
(show me why! Or maybe why not)
Answer:
NO
Step-by-step explanation:
3(1+3) = 8 - 2(1)
3(4) = 8 - 2
12 = 8 - 2
12 ≠ 6

Sarah has a large square piece of foam for an art project. The side lengths of the square are x in. To fit her project, Sarah cuts section of foam from two of the sies so now she has a rectangle. How much foam does Sarah cut from each of the two sides?
x^2 - 8x + 12
35 points!
Answer:
(x-6)(x-2)
Step-by-step explanation:
dont feel like explaining just trust me
The two sides of the rectangle will be (x - 6) and (x - 2).
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
Sarah has a large square piece of foam for an art project.
The side lengths of the square are x in.
To fit her project, Sarah cuts a section of foam from two of the sies so now she has a rectangle.
The area of the rectangle given by the expression will be
⇒ x² - 8x + 12
Factorize the expression, then we have
⇒ x² - 6x - 2x + 12
⇒ x(x - 6) - 2(x - 6)
⇒ (x - 2)(x - 6)
Then the two sides of the rectangle will be (x - 6) and (x - 2).

I am very confused... what is the question?
If the area is 22cm^2 what is the length of each side
okay so since the area is 22cm^2 , you will need to simplify it.
Which you will get 22*22 and the total would be 484. Which u will divide by 4 ( Square) to get each of the side your looking for.
So your answer is... 121

-7x +2 for x = -7
Answer:
51
Step-by-step explanation:
If x=-7, all we need is to substitute x for -7
-7x+2
-7×-7+2
-7×-7 is 49 because 7 times 7 is 49 and a negative times a negative is a positive.
Which leaves us 49+2
