Plug in the first equation into the he second equation
3x-(2x+7)=-9
3x-2x-7=-9
x-7=-9
x=-2
plug in x=-2 into the first equation
y=2(-2)+7
y=-4+7
y=3
answer: (-2,3)
We have to find how many purple rectangles does Olivia need for 3 scarves. We know that each scarf will have 5 rectangles and 2/5 of the rectangles will be purple: 2/5 * 5 = 2. It means that each scarf will have 2 purple rectangles. And for 3 scarves : 3 * 2 = 6. Answer: She needs <span>6 purple rectangles.</span>
the answer is 0.00116451016
hope it helped :)
Answer:
But the graph paper is not here...
F(x)=x³+4x²-5x+14
to express as linear product we proceed as follows:
f(x)=x³+4x²-5x+14
f(x)=x(x²+4x-5)+14
f(x)=x(x-1)(x+5)+14
Answer: f(x)=x(x-1)(x+5)+14
