For number 3 it says
X - 9 for x=-5
X-9 = ___ -9
It gave you your x so you would just substitute and in result you will have an equation of -5 -9
It would give you -14 , since it’s 2 negatives being added ,because you double tapped . Hope this helps :)

seropon [69]

Answer:

AB = 32 ft

Step-by-step explanation:

If you rotate Triangle ECD 180 degrees clockwise, you will see that the sides line up perfectly with Triangle BCA, meaning that ED = AB and ED = 32 (transitive property of equality) so AB must also equal 32.

Y=3x² + 7x - 10 y- 19x= 22

balu736 [363]

Answer:

Step-by-step explanation:

Step1: Solvex+y=7for x:

x+y=7

x+y+−y=7+−y(Add -y to both sides)

x=−y+7

Step2: Substitute−y+7forxinx+2y=11:

x+2y=11

−y+7+2y=11

y+7=11(Simplify both sides of the equation)

y+7+−7=11+−7(Add -7 to both sides)

y=4

Step3: Substitute4foryinx=−y+7:

x=−y+7

x=−4+7

x=3(Simplify both sides of the equation)

x=3 and y=4

ABCD is a rhombus with diagonals intersecting at E. If m

Butoxors [25]

*ABCD is a rhombus with diagonals intersecting at E. If m<ABC = 4m<BAD, find m<EBC.
Well, your question is a bit incomplete that makes it worse to give you exactly what you need. But, according to the fact that diagonals intersecting, all the angles =360 degrees.
Suppose $\ \textless \ BAD=x$ . and $\ \textless \ ABC=4x$
which means that opposite ones are equal
so, the solution is :
$2(x+4x)=360$
or could be $10x= 360

 x=36$
So, we have : <BAD=36 and <ABC=144
And the answer is : 4m+m=180.
Do hope you will find it helpful!
