1. what is the solution to the system of equations?
y = 5x - 7
-3x - 2y = -12
a. (2, 3)
b. (1, -2)
c. (-2, 9)
d. (3, 8)
what is the solution to the systems of equations represented by the 2 equations?
y = 4x + 3
y = -x - 2
a. (1, 7)
b. (-1, -1)
c. (2, -4)
d. (-3, -9)
a family went to an amusement park and paid $12 for each adult and $8 for each child. a group of 15 people went to the park and it cost $140. this system of equations models this situation, where x is the number of adults and y is the number of children.
how many children were in the group?
x + y = 15
12x + 8y = 140

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
