Answer:
Cost of 1 hamburger = $1.3
Step-by-step explanation:
Assume;
Cost of 1 hamburger = a
Cost of 1 French fries = b
On first trip
3a + 4b = 7.10......eq1
On second trip
2a + b = 3.40....eq2
From eq2 x 4
8a + 4b = 13.6....eq3
From eq3 - eq1
5a = 6.5
a = 1.3
Cost of 1 hamburger = $1.3

Memorize the side ratios of a 45-45-90 right triangle.
The ratio between the sides of this triangle is 1:1:Sqrt(2), which means that the length of the legs are equal, and the length of the hypotenuse is simply the leg length multiplied by the square root of two.

Answer:
y = 2x.
Step-by-step explanation:
The slope = (6 - (-4))/(3 - (-2))
= (6 + 4)/(3+2)
= 10/5
= 2.
Using this and the point (3, 6) we have:
y - 6 = 2(x - 3)
y = 2x - 6 + 6
y = 2x.
