Which equation describes the line that passes through points (2,5) and (0,9)?

Answer:

y = -2x+9

Step-by-step explanation:

We first need to find the slope

m = (y2-y1)/(x2-x1)

   = (9-5)/(0-2)

   = 4/-2

   = -2

We will use the slope intercept form of a line

y= mx+b where m is the slope and b is the y intercept

y =-2x+b

We know that 9 is the y intercept since x is equal to zero

y = -2x+9

How do i solve this ?
Murljashka [212]
You can choose a couple of the x-values and plug each into all of the x's in each equation on the right. Then see which equations give the y-values equal to the y's adjacent to the 3 x-values you used. I chose x=-4 and x=8. Only the 2nd, 3rd, and 5th equations matched with both.

Plz help ill give you brainlist plz
vekshin1
Simple you get the area of the inner rectangle, then the area of the 2 semi circles then add them.
First, you need to notice that the diameter of each circle is same as the side of the rectangle (46m), also not that the 2 semi circles will make a complete one circle with radius (46/2)
so now we are left with the area of the rectangle+the area of a circle with radius of 32m
The total area= (46*92)+(3.14*(32^2))= 7447.36m^2
and to keep you significant figures the answer is rounded to 3 digits, so the final answer will be 745m^2.
Hope this helps, thanks.

Which of the following sets of numbers could be the lengths of the sides of a triangle?
kicyunya [14]

Answer is C. 8, 3, 6

To answer this, you must know the Triangle Inequality Theorem.

The two shortest sides when added together, must be greater than the longest side.

A. 2 + 4= 6 which can't work since it equals the longest side of 6

B. 4 +2=6 The sum would be less than 8, which doesn't work

C. 6 +3 = 9 the sum is greater than 8, which makes it a triangle

D. 3 +8 = 11 11 is less than 12

Find the base of a parallelogram with a slant height of 7cm and an perimeter of 63 cm2
vlada-n [284]

Base of parallelogram b = 24.5 cm

Step-by-step explanation:

We are given:

Perimeter =P= 63 cm^2

Slant Height =a= 7 cm

Base of Parallelogram =b= ?

The formula used is:

Perimeter = 2(a+b)

where a is height and b is base

Putting values:

Perimeter = 2(a+b)\\63=2(7+b)\\63=14+2b\\2b=63-14\\2b=49\\b=\frac{49}{2}\\b=24.5

So, Base of parallelogram b = 24.5 cm
