In ΔDEF,{EF}\cong{DE} EF ≅ DE and m∠E = 104°. Find m∠D.
Alexeev081 [22]

The 3 inside angles need to equal 180.

Subtract E from 180 to find the sum of the other two angles:

180 - 104 = 76

Now because EF ≅ DE , angle D and F would be the same so divide 76 by 2

Angle D = 38

(Q1) Which of the following is true about the function y = 3 • 2x?
Virty [35]

Answer: Third option

Step-by-step explanation:

You have the function:

y=3*2^x

Then, if the value of x increases by 1, you obtain:

-Rewrite the function:

y=3*2^{(x+1)}

-Substitute values for x into the function and observe what happen to y. Then:

x=1

y=3*2^{(1+1)}=12

x=2

y=3*2^{(2+1)}=24  

x=3

y=3*2^{(3+1)}=48  

The value of y is doubled.

How can I find the co-ordinatie of their point of intersection?
alisha [4.7K]
Combine the two equations so that it’s 2x+5=4x-1 and then subtract 2x from both sides. now it’s 5=4x-1 and add 1 to both sides. now is 6=4x 6 divided by 4 is 1.5 so that is the x value. now sub 1.5 as the x value into the first equation so it’s y=2(1.5)+5. you do the math and it’s y=8 (because 1.5 times 2 is 3 and 3+5 is 8) then your point is (1.5,8)
