Step-by-step explanation:
The given equation is :
2x+7y=11
We need to tell the point (-5,3) lies on the graph of the above equation of not.
Put x = -5 and y = 3 in the LHS of the above equation.
LHS = 2x+7y
= 2(-5)+7(3)
= -10 +21
= 11
It means, when we put x = -5 and y = 3 in the above equation, we get 11. Hence, (-5,3) lies on the graph of the equation.
Answer:
For #6, it is 81 degrees, and for #8, it is 100 degrees.
Step-by-step explanation:
For #6, it is on the opposite side, so 81 degrees
For #8, it is also on the opposite side, so 100 degrees
Whenever there are parallel lines going horizontally, the angles measure the same on opposite sides, and to find the measure of an angle next to another angle, subtract it from 180.
First, divide 648 by 9. 648/9=72. Now we know that Ashley covers 72 miles in an hour. In order to get the number of miles she covers in 7 hours we must multiply 72 by 7 which equals 504. So Ashley would drive 504 miles in 7 hours.
24 - 13 = 11
Simple subtraction I'm guessing
The constant rate of change is 8...any questions?
