Answer:
Make a line connecting points (0,0) (1,5) and (-1,-5)
Step-by-step explanation:
Okay, so you have to start your first point at (0,0), which is the origin, because there is no y-intercept in the equation.
Next you use slope, Rise/Run to plot your next point. In the equation y=mx+b, the slope is in m. So in y=5x, the slope is 5/1 .
So, you're going to move up 5 from the origin and move to the right once, which will give you the point (1,5).
If you need another point to make a line go the opposite way from the origin. So we would go down 5 and left 1. That would give us the point (-1,-5)
Hopefully this helps! Leave a comment if it does and I suggest asking your teacher to make sure it's correct!
Give the equation for the line: please someone answer this for me woth 20 points!!!!!
Answer:
y=x/4
Step-by-step explanation:
slope =y2-y1/x2-x1
=1-0/4-0=1/4
Answer: slope intecept form: y = 1/4x
Step-by-step explanation: first we need to find the slope:
Since we have the coordinates (0,0) and (4,1), we can find the slope, which we find 1/4. We can double check this by seeing if the next point is found +4 to the right and up 1.
We have y = 1/4x + b right now, so we need to find the y intercept, in which case is zero because it goes through the origin.
So your final answer is y = 1/4x + 0, or y = 1/4x for short.

Joe wants to make a path around the outside perimeter of his vegetable garden which is 50’ x 70’. If the path is of uniform width and the entire garden and path are to cover a surface area of 4524 sq feet how wide should the path be
We will see that the path should be 4 feet wide.
How wide should the path be?
For a rectangle of length L and width W, the area is:
A = L*W
In this case, we know that the dimensions of the garden are:
L = 50 ftW = 70 ftNow if we add a path of width x that surrounds it, the new length and width will be:
L' = 50 ft + 2xW' = 70 ft + 2xAnd the area of this rectangle must be 4524 ft^2, then we have:
(50 ft + 2x)*(70 ft + 2x) = 4524 ft^2
Now we can solve this for x.
Ignoring the units, so the math is easier to read, we have:
(50 + 2x)*(70 + 2x) = 4524
50*70 + 50*2x + 2x*70 + 2x*2x = 4524
3500 + 240x + 4x^2 = 4524
4x^2 + 240x + 3500 - 4524 = 0
4x^2 + 240x - 1024 = 0
Now to simplify the quadratic equation, we can divide both sides by 4 to get:
x^2 + 60x + 256 = 0
The solutions of the quadratic equation are given by Bhaskara's formula:
[tex]x = \frac{-60 \pm \sqrt{60^2 - 4*1*(-256)} }{2*1} \\\\x = \frac{-60 \pm 68 }{2}[/tex]
We only care for the positive solution (the negative one does not make physical sense).
x = (-60 + 68)/2 = 4
So the width of the path must be 4 ft.

What are the values of angles 1 and 2?
Answer:
45o
Step-by-step explanation:
Angles 1 and 2 form a linear pair and are supplementary. So to find m∠2, subtract m∠1 from 180o. m∠2 = 180o - 135o = 45o.
Answer: 90
Step-by-step explanation:
You can write "the measure of angle 1" as m ∠1. ∠1 and ∠2 are complementary, and m ∠2 = 32. Find m ∠ 1. m ∠1 + 32 = 90 Substitute 32 for m ∠2.

Julissa has 15 stamps and Ethan has 14 stamps. Pawel has three times the number of stamps as Julissa and Ethan combined. Julissa thinks that 100 is a reasonable estimate for the number of stamps that Pawel has.
What is an estimate of the number of stamps that Pawel has? Is 100 a reasonable total?
32; 100 is a reasonable total
90; 100 is a reasonale estimate
213; 100 is not a reasonale estimate
630; 100 is not a reasonale estimate
Answer:
B. 90; 100 is a reasonable estimate
Step-by-step explanation:
15 + 14 = 29 (combined number of stamps Julissa and Ethan have)
Pawel has three times 29 stamps
29 ×3 = 87 (number of stamps Pawel has)
90 is the closest estimate to the amount of stamps Pawel has.
Therfore, 90 is the correct estimate and 100 is a reasonable estimate.

Write the equation of the line that passes through (-1,8) and is parallel to the graph of y = 4x - 2
Answer:
When a line is parallel to another line, they have the same slope. So far the equation would be, y=4x+b. To find the value of b, substitute the given point into the equation.
8=4(-1)+b
8=-4+b
b=12
So, the equation of the line is y=4x+12.

4(9x + 11) + 5(3x + b) = ax + 9
I gotta find a and b in the next 10 minutes lol-
Answer:
a = 51 , b = - 7
Step-by-step explanation:
Expand and simplify left side , then compare like terms on both sides.
4(9x + 11) + 5(3x + b) ← distribute parenthesis
= 36x + 44 + 15x + 5b ← collect like terms
= 51x + 5b + 44
Compare terms with right side ax + 9
Compare x - terms
51x and ax
For these terms to be equal then
a = 51
Compare constant terms
5b + 44 and 9
For these terms to be equal , then
5b + 44 = 9 ( subtract 44 from both sides )
5b = - 35 ( divide both sides by 5 )
b = - 7

18x + 5y = 10
Answer: y-int = 2
Step-by-step explanation:
set x=0
so 18(0) + 5y = 10
solve for y by dividing both sides by 5
5y/5 = 10/5
y=2

Solve the equation-
[tex] \frac{5}{x - 3} - \frac{4}{x + 4} = \frac{1}{x} [/tex]
Hello studentUnion!
[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]
Solve the equation-
[tex] \frac{5}{x - 3} - \frac{4}{x + 4} = \frac{1}{x} \\ [/tex]
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
[tex] \frac{5}{x - 3} - \frac{4}{x + 4} = \frac{1}{x} \\ [/tex]
Let's multiply both the sides of the equation by x (x - 3) & (x + 4) which is the LCM of (x - 3), (x + 4) & x. We can't solve it directly without taking the LCM first as the denominators are not equal to each other. Then do cross multiplication. After all these steps, you'll get an equation as..
[tex]x\left(x+4\right)\times 5-x\left(x-3\right)\times 4=\left(x-3\right)\left(x+4\right) \\ [/tex]
Now, use the distributive property & simplify it.
[tex]x\left(x+4\right)\times 5-x\left(x-3\right)\times 4=\left(x-3\right)\left(x+4\right) \\ \left(x^{2}+4x\right)\times 5-x\left(x-3\right)\times 4=\left(x-3\right)\left(x+4\right) \\ 5x^{2}+20x-x\left(x-3\right)\times 4=\left(x-3\right)\left(x+4\right) \\ 5x^{2}+20x-\left(x^{2}-3x\right)\times 4=\left(x-3\right)\left(x+4\right) \\ 5x^{2}+20x-\left(4x^{2}-12x\right)=\left(x-3\right)\left(x+4\right) \\ 5x^{2}+20x-4x^{2}+12x=\left(x-3\right)\left(x+4\right) \\ x^{2}+20x+12x=\left(x-3\right)\left(x+4\right) \\ x^{2}+32x=\left(x-3\right)\left(x+4\right) \\ x^{2}+32x=x^{2}+x-12 \\ x^{2}+32x-x^{2}=x-12 \\ 32x=x-12 \\ 32x-x=-12 \\ 31x=-12 \\ \boxed{ \boxed{ \bf \: x=-\frac{12}{31} }}[/tex]
