Answer:
The pairs of ( x,y) are ( -3 ,16) , ( 0,1) and ( 3,4)
Step-by-step explanation:
y = ( x -1)²
y = x² - 2 x + 1
for x = -3
y =( -3)² - 2 × -3 + 1
= 9 +6 +1
= 16
so ( x, y) = ( -3 , 16)
for x = 0
y = 0² - 2 ×0 + 1
= 1
so ( x,y) = ( 0,1)
For x = 3
y = 3² - 2 × 3 +1
= 9 - 6 +1
= 4
( x,y) = (3 , 4)
so the pairs of ( x,y) are ( -3 ,16) , ( 0,1) and ( 3,4)
Answer:
2)16.5
Step-by-step explanation:
step1:v/2.2 -0.1=7.4
add 0.1 on both sides
step2:v/2.2=7.5
multiply by 2.2 on both sides
step3:v=16.5
2) v/2.2 - 0.1 = 7.4
v/2.2 = 7.4 + 0.1
v /2.2 = 7.5
v = 7.5 * 2.2
v = 16.5
4) -1.3g + 1.9 = -11.1
-1.3g = -11.1-1.9
-1.3g = -13
g = -13/-13
g = 1
6) -14.3 = -1.4 -3d
-14.3 + 1.4 = -3d
-12.9 = -3d
3d = 12.9
d = 12.9/3
d= 4.3
3.14 = Pie
