Answer:
(-2,-2)
Step-by-step explanation:
for question number 15...cordinated grid shows each equation...first equation is represented by straight line going upwards through +4 in y axis...(y=3x+4)...
point is....every point in this two lines represent a possible x and y value for each equation...and there is a point where these lines meet each other....in that point...x and y values are possible values for both equations.so answer is (-2,-2)...this cordination satisfy each pairs of equation...you can try using -2 for x in both equations and get -2 as the answer for y...that proves the point..try it for 16 quiz.good luck

Answer:
A=-28 B=-48 C=45
Step-by-step explanation:
-(7x4)= -28 so your first step is multiply the positive and the negative equals a negative (+)x(-)=(-) second is to multiply the numbers
-(6)x8= -28 same steps for the first
(-5)x(9) convert it to 5x9=45
