a student is trying to solve the system of two equations given below:

equation p: y + z = 6
equation q: 8y + 7z = 1

which of the following is a possible step used in eliminating the y-term? (1 point)

(y + z = 6) • –8

(y + z = 6) • 7

(8y + 7z = 1) • 7

(8y + 7z = 1) • 8

(y + z = 6) • –8

Step-by-step explanation:

Because in order to eliminate 8 you will need to multiply by a negative number so that you can eliminate a positive number.

Hope this helped!

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
