Answer:
f(-3)=3
Step-by-step explanation:
Plug in -3 for x.
f(-3)=-4(-3)-8
f(-3)=12-8
f(-3)=3
Hope this helps!
If not, I am sorry.
Answer:
-12
Step-by-step explanation:
Find the decimal equivalent of 2 1/3
2 1/3 = 7/3 = 2.333333
(4x + 9)/ 2.333333 = 3x / 0.5 Now cross multiply
0.5 * (4x + 9) = 3x * 2.333333
2x + 4.5 = 7x Transfer 2x to the right side.
4.5 = 5x
x = 4.5/5
x = 0.9
We'd best check this one
Left hand side.
(4x + 9)/2.333333
(4*0.9 + 9)/2.333333
(3.6 + 9)/2.333333
12.6/2.333333
5.4
Right hand side
3x/0.5
= 3*0.9/0.5
= 2.7/0.5
= 5.4
And it checks.
Answer:
Step-by-step explanation:
First find circumference of circle: C=2r = 18.84
Rectangle area = 18X13 = 244.92
Area of circles is (pi)r^2 = 28.6
244.92+28.6+28.6 = 302
Triangles FGH and ABC are congruent because of the: AAS congruence theorem.
<h3>What is the AAS Congruence Theorem?</h3>
The AAS congruence theorem states that when two angles and one non-included side in one triangle are congruent to corresponding two angles and one non-included side in another triangle, then both triangles are congruent.
In the proof given, it is established that both triangles have two corresponding congruent angles, and also, BC ≅ GH which are non-included sides.
Therefore, both triangles are congruent because of the AAS congruence theorem.
