y=2 x+8
y=2 x+4
y=-2x+4
y=-2 x+8
Answer:
Step-by-step explanation:
y=mx+b
m=dy/dx=(0-8)/(4-0)=-8/4=-2
y=-2x+b, using point (4,0)
0=-2(4)+b
b=8
y=-2x+8

Answer:

Step-by-step explanation:
Find the equation of straight line passing through the point:
a) (4,8) and parallel to the line 3x+y=17
b) (2,3) and perpendicular to the line y=2x+13
I need the answers ASAP please!
Answer:
See solution below
Step-by-step explanation:
Standard equation of a line in point slope form is expressed as y-y0 = m(x-x0)
m is the slope
c is the intercept
Fr the equation 3x+y = 17
y = -3x+17
m = -3
Given the point (4,8)
The equation of the line is expressed as;
y - 8 = -3(x-4)
y - 8 = -3x + 12
y + 3x = 12+8
y+3x = 20
This gives the required equation
For the equation y = 2x + 13
Slope m = 2
Since the line is perpendicular to the unknown line;
M = -1/2
Given the point (2, 3)
Get the equation
y - 3 = -1/2(x - 2)
2(y-3) = -(x - 2)
2y-6 = -x+2
2y+x = 2 + 6
2y+x = 8
This gives the required equation

Answer:
x° = 29°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relevant trig relationships. Here, you have the hypotenuse and the side opposite the unknown angle. So, the appropriate relation is ...
Sin = Opposite/Hypotenuse
sin(x°) = 12/25
x° = arcsin(12/25) ≈ 28.69°
The value of x is about 29.

Answer:
[tex] - 11 \frac{1}{2} [/tex]
Step-by-step explanation:
8x + 5y = 7
4x - 5y = 11
If you all it all up we have
8x + 4x +5y - 5y = 18
12x=18
x=18/12=1.5=3/2 = 1 whole number 1 over 2(1 1/2)
subtituting the value of x into equation 1(8x + 5y = 7)
8(1.5) + 5y = 7
5y=7-12
5y = -5
y=-5/5
y= -1

Find the area of the figure. (Sides meet at right angles.)
Answer: 37ft^2
Step-by-step explanation:
Create two separate figures. A full square 3x3 and a rectangle 7x4.
The 7ft line on the right minus 3 ft (because we are cutting out that section of the figure) = 4ft
Area of 3x3 square = 3^2 = 9ft^2
Area of 7x4 rectangle = 7x4 = 28ft^2
28+9= 37ft^2

Which of the following statements must be true?
A. The measure of angle AGB is greater than the measure of angle ADE.
B. The measure of angle AGB is greater than the measure of angle AED.
C. Segment AE and Segment AB have the same length.
D. The ratio of AG to AE is the same as the ratio of AB to AD.
Answer:
D
Step-by-step explanation:
....iam not sure but i think its a because the other impossible
Answer:
The answer is D.
Step-by-step explanation:
For A- I don't think it's greater, I think they are the same.
For B- I don't think it's greater, I think they are the same.
For C- Segment AE is longer than Segment AB.
So D seems like the more logical answer.

Answer:
g has an average rate of change of zero at the intervals [-5,4] and [-2,2]
Step-by-step explanation:
When we talk of the average rate of change, we mean the change in y values divided by the change in x values
Once the change in y-values is zero, then over that interval, the average rate of change is zero
at the point t =- 5, g(t) = 6; at the point t = 4, g(t) = 6
As we can see here, within the interval [-5,4]; the average rate of change is 0
This same pattern is repetitive at points or ranges where we have same values for g(t)
such as;
[-2,2]

A restaurant is making table cloths for their four round tables. Each table is a circle with a radius of 2 ft. Each table cloth needs to be 20% larger than the table surface.
How many whole table cloths can the restaurant get out of a piece of fabric with an area of 64 ft²?
Please help!!
Answer:
4
Step-by-step explanation:
Since it gives us the amount of area of material to use we know we want to find how many times we can divide it into tablecloths. So now we need to find how much each tablecloth is.
so first it tells us that each table has a radius of 2 ft, so we find the area using that. area of a circle is [tex]\pi r^2[/tex] so plugging in 2 ft we get 4π square feet or 12.56.
It also says that each tablecloth needs to be 20% bigger, so we find what 20% larger than 4π is. to do this you do 4pi*1.2 = 4.8π = 15.072 square feet.
Now, how many tablecloths with areas of 15.072 square feet can be made from 64 square feet. Hopefully it's obvious you divide. so 64/15.072 = 4.25
Since we want whole tablecloths and that .25 is a remainder, 4 whole tablecloths can be made.
1. What is the product of 1/2x - 1/4 and 5x^2+6
show your work
Answer:
Step-by-step explanation:
First you would make the equation
(1/2x - 1/4)(5x^2 + 6)
afterwards you would multiply like normal binomials\
5/2x^3 + 3x - 5/4x^2 - 6/4
Then simplify
5/2x^3 - 5/4x^2 + 3x - 3/2
Remember to put them in order from the most roots to the least.
