X= -1/3 Because the perpendicular lines always have a opposite reciprocal meaning if a slope is Positive it turns negative and the denominator becomes the numerator ex.3 is the same as 3/1 and the opposite of that would be 1/3 and if the slope is negative then the opposite reciprocal will be positive and with the denominator becoming the numerator
Answer:
B
Step-by-step explanation:
The solution to a system of equations is where the two lines intersect at the exact same (x,y).
On the graph below, the point of intersection is between x values -6 & -7 and between y values -3 & -4. The best estimate would be half way between each of these values.
(-6.5, -3.5)
Answer:
210 miles
Step-by-step explanation:
70x3 70mph for 3 hours
399,499.
Since we are rounding to the nearest thousand, we are going to be focusing on mainly 39(9,499). The rule I learned is, "5 or above, give it a shove". Since it isn't 500 or above, we have to round it down to 9,000.
The total is 399,000.
