Triangle ABC is shown below with line DE passing through points D and E: Triangle ABC is shown with point D lying on side BC and

point E lying on side AC. Line DE is perpendicular to side AC. If triangle ABC is dilated about the center of the triangle to create triangle A'B'C', dilated line D'E' will be parallel to DE be perpendicular to DE lie on the same line as DE shift five units to the right

Answer:

It is given that, A Triangle ABC in which point D lying on side BC and point E lying on side AC.Line DE is perpendicular to side AC.

Now, triangle ABC is dilated about the center of the triangle to create triangle A'B'C' in such a way that D' lies on side B'C' and E' lies on side A'C'.

Both the line segment that is line segment DE and line segment D'E' will be parallel.

Option 1:Dilated line D'E' will be parallel to DE

F(-1) f(x) = -3x2 + 2x - 7
egoroff_w [7]

Answer:

f(-1) = -12

Step-by-step explanation:

<u>Step 1:  Set x to -1 and solve</u>

<u />f(x) = -3x^2+2x-7

f(-1) = -3(-1)^2+2(-1) - 7

f(-1) = -3(1) - 2 - 7

f(-1) = -3 - 2 - 7

f(-1) = -12

Answer:  f(-1) = -12

One term of (x+y)^m is 31,824x^18y^11<br> What is the value of m ?
alisha [4.7K]

Answer: The value of m is 29.

Step-by-step explanation:

Given that, One term of (x+y)^m is 31,824x^{18}y^{11}  ...(i)

We know that that (r+1)th term in (a+b)^n is given by :-

T_{r+1}=^nC_ra^{n-r}b^r  ...(ii)

On comparing (i) with (ii) , we get

a= x \text{ and } b= y \\n-r =18 \text{ and }  r=11\\n=m

i.e.

m-r=18\Rightarow\ m-11=18\\\\\Rightarrow\ m=18+11=29

Hence, the value of m is 29.

If the measure of angle 2 is 3x, and the measure of 1 is 5x - 12 what is the measure of angle 9 ?
Mariana [72]
3x+5x-12=180
8x=180+12
8x=192
x=192/8
x=24

angle 1 = 5x-12
=5(24)-12
=120-12
=108

angle 2= 3x =3*24=72

angle 1 = angle 9
angle 9= 108
