5y - 3 = 3y + 27
2y = 30
y = 15

m<A= 5(15) - 3 = 75 - 3 = 72

m<B = [360 - 2(72)]/2
m<B = [360 - 144] / 2
m<B = 216 / 2
m<B = 108

HELP ME PLEASE!!! What is the value of y for the parallelogram shown A. 66 B. 60 C. 22 D. 38

Nesterboy [21]

Answer:

Option C is the correct option.

Solution,

 $3y = 66$ 

(opposite angles of parallelogram are equal )

 $or \: 3 \times y = 66 \\ or \: y = \frac{66}{3} \\ y = 22$ 

hope this helps...

Good luck on your assignment..

Let T:P3â†’P3 be the linear transformation such that T(â’2x2)=3x2+4x, T(0.5x+3)=â’3x2+3xâ’4, and T(2x2â’1)=â’3x+4. Find T(1), T(

balu736 [363]

It looks like we're told that

$T(-2x^2)=3x^2+4x$

$T\left(\dfrac12x+3\right)=-3x^2+3x-4$

$T(2x^2-1)=-3x+4$

We use the fact that $T$ is linear to find $T(1),T(x),T(x^2)$ . First, we notice that

$T(-2x^2)+T(2x^2-1)=T(-2x^2+2x^2-1)=T(-1)=-T(1)$

We also have

$T\left(\dfrac12x+3\right)=T\left(\dfrac12x\right)+T(3)=\dfrac12T(x)+3T(1)$

$T(2x^2-1)=T(2x^2)-T(1)=2T(x^2)-T(1)$

So once we find $T(1)$ , we can determine $T(x)$ and $T(x^2)$ . We have

$T(1)=-\left(T(-2x^2)+T(2x^2-1)\right)\implies T(1)=-3x^2-x-4$

and using this we find

$T(x)=12x^2+12x+16$

$T(x^2)=-\dfrac32x^2-2x$

Then

$T(ax^2+bx+c)=T(ax^2)+T(bx)+T(c)=aT(x^2)+bT(x)+cT(1)$

$T(ax^2+bx+c)=-\dfrac32\left(a-8b+2c\right)x^2-(2a-12b+c)x+16b-4c$

Need help this id due in a hour!!

zimovet [89]

Answer:

Step-by-step explanation:

angles on a straight line add up to 180 degrees

so 180 - 127= 53 to get the angle on the bottom left.

60 + 53 = 113

angles in a triangle add up to 180 degrees so 180-113= 67

to double check you should add

60+53+67 if you get 180 then its correct!

hope it helps :)
