PLS ANSWER QUICKLY!!

Mathematics
1 answer:
olganol [36]2 years ago

Answer:

EF=6

Step-by-step explanation:

E is the midpoint, so DE = EF

DE = 15-3x

EF = x+ 3

Since DE = EF,

15 - 3x = x + 3

-4x = -12

x = 3

If x = 3,

DE = 15 - 3*3,   15 - 9 = 6

EF = x+ 3, so EF = 3 + 3 = 6

Write a proof for the biconditional using the inverse and contrapositive.
MariettaO [177]
I don’t really understand the question at hand but let me try to help

X is equal to 4 we know this because because the sign in between the number means greater than or equal to so 3 x 4 equals 12 and that makes the equation on right true and on the left x is also equal to for which also makes the statement on the right true as well so I think X = 4

I hope I was able to help and If not I’m sorry

Help ASAP. Can somebody please tell if this is the correct answer. If not put the correct answer And help me if I need to graph
RSB [31]

Answer: closed circle pointing to the right.

Step-by-step explanation:

Given that the inequality equation is

6 ( 2 - 3y ) < = 36

Open the bracket

12 - 18y < = 36

Collect the like terms

- 18y < = 36 - 12

Make y the subject of formula

The inequality sign will change the moment you multiply or divide both sides by negative numbers

Y > = - 24/18

Y > = - 4/3

That is y is greater than or equal to negative 4/3

Graphing the above inequality,

The point will be between -2 and -1. And it will be closer to -1.

The arrow will point to the right and it will be a closed circle since it is greater than or equal to.
