100 POINTS FOR BRAINLIEST! according to the image, whats the answer? Answer wisely for the full 100

lesantik [10]

Answer:

Step-by-step explanation:

To find the area of a semicircle the formula is

$\frac{\pi r^2}{2} \\=\frac{\pi 1^2}{2} \\=6.283m^2$

The square

$A=a^2=2^2=4m^2\\6.283+4=10.283m^2$

$A=wl=7*9=63m^2$ (rectangle)

$A=\frac{ab}{2} =\frac{6*4.5}{2} =13.5m^2\\63+13.5=76.5m^2$ (triangle)

Help please I can’t figure it put

leonid [27]

5y + 3 > -7 y + 13

Subtract 3 from both sides

5y > -7y + 13 - 3

Add 7y to both sides

5y + 7y > 13 - 3

12y > 10

Divide by 12, which is positive so the sign doesn't flip

y > 10/12 = 5/6

Answer: y > 5/6

Find the equation of a line parallel to the line 2x-y-9=0 and passing through the point of intersection of the lines 5x+y+4=0 an

Cerrena [4.2K]

Answer:

$y=2x-3$

Step-by-step explanation:

1. Using the point of intersections, we use the substitution method to find the coordinates of the line parallel to $2x-y-9=0$

$5x+y+4=0$

$y= -4-5x$

substituting the value of y in $2x+3y=1$ :

$2x +3(-4-5x)=1\\\\2x-12-15x-1=0\\-13x=13x\\x= \frac{13}{-13}= -1$

substituting x=-1 in y= -4-5x:

$y= 1$ (upon solving, you should get this)

$(x,y)= (-1,1)$

2. Using y=mx+c and making y the subject of the formula 2x-y-9=0 and using the coordinate we found earlier, we will find the equation of the parallel line. (We make y the subject of the formula to find the gradient)

$2x-y-9=0\\2x-9=y\\y= 2x-9$

$y= mx+c\\$

-1= 2 x 1 +c

-3=c

y= 2x-3
