Eldar cooks lasagna and spaghetti using pesto sauce. let l represent the number of batches of lasagna and s represent the number of batches of spaghetti that eldar can cook with the amount of pesto sauce he has. 0.9l+0.3s \leq 60.9l+0.3s≤6

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
