This isi 5 points but whatever
if x=-4, y=3 and z=2
2(-4)²-2(2)⁴+(3)²-(-4)²+(2)⁴=
2(16)-2(16)+9-(16)+16=
32-32+9-16+16=
0+9+0=
9
Answer:
15
Step-by-step explanation:
Plug the number into the equations
Answer:
I believe its -7/5 unless they want -7/-5
Step-by-step explanation:
(4,3) (-1,-4)
X1,y1 x2,y2
And it should be
Y2-y1
X2-x1
-4-3 = -7
Over
-1-4 = -5
So -7/5 or -7/-5 whatever your teacher perfers
Hope this helps
(0, -2) and (1, 1) both work in this system of equations.
The best way to find if it is a solution is to look for those points on the graph. When you graph the point, it needs to fall in an area where both lines or shaded or on a solid line.
(0, -2) falls on a solid line.
(1, 1) falls in the double shaded area.

Answer:
(40π +48) cm²
Step-by-step explanation:
The total area is the sum of the areas of a 12 cm circle, a 4 cm circle, and a 12 cm by 4 cm rectangle.
For a given diameter (d), the area of a circle is ...
A = (π/4)d²
Then the area of the two circles is ...
A = (π/4)(12 cm)² +(π/4)(4 cm)² = (π/4)(144 cm² +16 cm²) = 40π cm²
The area of the rectangle is ...
A = LW
A = (12 cm)(4 cm) = 48 cm²
Then the total area of the figure is ...
total area = circle area + rectangle area
total area = 40π cm² +48 cm²
total area = (40π +48) cm²
