Answer:
Step-by-step explanation:
3x(5x+8y)=15x^2+24xy
4x(3x^2+5x-7)=12x^3+20x^2-28x
(3x+4y)(2x-7y)=6x^2+8xy-21xy-28y^2=6x^2-13xy-28y^2
(2-3a)(2a^2-3a+7)=4a^2-6a+14-6a^3+9a^2-21a=-6a^3+13a^2-27a+14
Answer: 74.25 Php, 4.45kg, 182 Php, 30 People, and 315 Php
Step-by-step explanation:
1. 200-125.75= 74.25 Php
2. 1.5+1.7+1.25=4.45kg
3. 45.50*4 = 182 Php
4. 45/1.5 = 30 People
5. 35.00*9 = 315 Php
Answer: B
Step-by-step explanation: I am just Gussing
Answer:
Step-by-step explanation:
So first, we know (-x,-y) reflected across y axis is (x,-y). and (x,y) reflected across y axis is (-x, y). So we can apply this to get (-4,-1) to (4,-1). (2,6) to (-2,6).
Answer: Yes
Step-by-step explanation:
First multiply the first equation by three to get 3x+12y=69
Then subtract 12y from both sides of the second equation
Then add the first system and the second like this:
Because 0≠70, the system has no solutions
