Ms. Whipple asked her sixth grade students what after-school sport they participated in. She kept track of their answers and created this table Based on the ratios from Ms. Whipple's class which proportion could be used to find r the number of students expected to participate in soccer, if there are a total of 350 sixth graders at the school?

a- 22/11 = r/ 350 - 22

b- r/350 = 11/22 - 11

c- 11/22 = r/350

d- r/22 = 11/350

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
