Answer:
Slope = 9
Step-by-step explanation:
(-7 , -2) ; x₁ = -7 and y₁ = -2
(-6 , 7) ; x₂ = -6 and y₂ = 7
Slope = 
![=\frac{7-[-2]}{-6-[-7]}\\\\=\frac{7+2}{-6+7}\\\\=\frac{9}{1}\\\\= 9](https://tex.z-dn.net/?f=%3D%5Cfrac%7B7-%5B-2%5D%7D%7B-6-%5B-7%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B7%2B2%7D%7B-6%2B7%7D%5C%5C%5C%5C%3D%5Cfrac%7B9%7D%7B1%7D%5C%5C%5C%5C%3D%209)
Answer:
The rate of change is "-3". Which means the rate at which the tractor uses fuel.
Step-by-step explanation:
The equation describes a line and any line follows the equation:
y = m*x + c
Where "m" is the rate of change and "c" is the shift on the line. Comparing the equation for the fuel and the equation from the line, the rate of change must be "-3". The rate of change in this context describes the speed at which the tractor uses fuel, at a rate of 3 gallons per hour.
Okay. So when it comes to combining like terms, they should have the same variable and power. They dont have to be the exact same number, but they should at least have the same terms. In the expression 40 + 15e + 10e, 15e and 10e both have like terms, because they have the same variable. 15e + 10e is 25e. 40 has no like term, so that is left alone. The expression simplified is 40 + 25e.
£15
If you add the two ratios together you get 10. Which means that the £50 is made up of 10 pieces. To get Doras amount you have to divide 50 by 10 which is five, and then times the number by how many pieces Dora has, which would be 5x3=15
The answer is 0.13 because it has the highest number in the tens place.
