Can someone help me plz The San Francisco half-marathon is a 13.6-mile race that travels up and down the hills of San Francisco. One street, Folsom Street, has a slope that can be represented by the function 2y=4x+7. Another street, Divisadero Street, has a slope that can be represented by the function 5y = 2x +9.

Which of these hills would you rather run-up? Why? Use evidence to support your answer.

What’s the numerical coefficient of 6xy

What is the solution to the system of the equations? x = y - 3 x + 3y = 13

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
