Point at (0,-3) and another point at (1,1)....draw a straight line through the points and draw arrows at the end, symbolizing that the line goes to infinity
J is between H and K.if HJ =4t -15 ,JK=5t-6, and KH=15,find JK.
Answer:
7.2×10−5 the -5 is the exponent
Step-by-step explanation:
You have to move the decimal where there is no zeros when ever you move the decimal to the right is a positive and when ever you move the decimal to the left is a negative exponent for example: 0.0000568 is
5.68 × 10-5 the -5 is the exponent. The positive is 450000= 4.5×10 5 the 5 is the exponent
You have the correct axis of symmetry value. Nice work.
Plug that x value into the equation to get...
y = -2x^2 - 12x - 10
y = -2*(-3)^2 - 12*(-3) - 10 <<-- replace every x with -3; then use PEMDAS
y = -2*(9) - 12*(-3) - 10
y = -18 + 36 - 10
y = 18 - 10
y = 8
The vertex is the ordered pair (-3, 8)
Note: the axis of symmetry is the vertical line through the vertex
