Tanica drew a line of best fit on a scatterplot, as shown below. On a graph, a trend line has a negative slope.
The equation of the line is y almost-equals negative 1.02 x + 7.09. Using the line, she predicted that when the value of x is 0.5, the value of y will be approximately 7.6. What was her mistake?
She drew the line of best fit incorrectly.
She used the line of best fit to predict y for an incorrect value of x.
She forgot the minus sign before the first term on the right side of the equation when she predicted y.
She plugged 0.5 into the equation for y instead of x and actually predicted x instead of y.

Labc is reflected across x = 1 and y = -3. what are the coordinates of the reflection image of a after both reflections?

3x + 4y = 5 x- 3y = -7 solve by substitution

On the way home from visiting his family, vincent’s plane cruised at an altitude of 3.2 × 10^4 feet. he had heard that a man named felix baumgartner skydived from an altitude of 1.28 × 10^5 feet. vincent wants to know how much higher felix went on his skydiving trip. question 1 you have already seen how adding numbers works in either scientific notation or standard notation. but can you subtract numbers in scientific notation and get the same results as subtracting in standard notation? to find out, first solve vincent’s problem in standard notation. part a write the cruising altitude of vincent’s plane in standard notation.
