Answer:
x = ± 4
y = - 2
Step-by-step explanation:
y = 0.5x² - 10 ------------------------(I)
y = -x² + 14 ------------------------(II)
Substitute the y value in equation (II)
0.5x² - 10 = -x² + 14 {Add x² to both sides}
0.5x² + x² -10 = 14 {combine like terms}
1.5x² - 10 = 14 {Add 10 to both sides}
1.5x² = 14 + 10
1.5x² = 24 {Divide both sides by 1.5}
1.5x²/1.5 = 24/1.5
x² = 16
x = ±4
Substitute x = 4 in (I)
y = 0.5 * 4² - 10
= 0.5*16 - 10
= 8- 10
y = -2
Substitute x = -4 in (I)
y = 0.5 * (-4)² - 10
= 0.5*16 - 10
= 8- 10
y = -2
Answer:
55
Step-by-step explanation:
6m+90=96m
Answer:
It's a rotation clockwise of 90 degrees about the origin.
Step-by-step explanation:
The given point moves from y = 5 to x = 5 so it has passed through 90 degrees about the origin.
It's a rotation clockwise of 90 degrees about the origin.
Make an equation.
'is' is an equal sign
The blank can be 'x'
'of' = multiplication
18 = x * 30
Multiply:
18 = 30x
Divide 30 to both sides:
x = 0.6
Multiply by 100:
0.6 * 100 = 60%
