First find x: y= -2x+4 so you take that and substitute it into your second equation -x+3(-2x+4)=-9 ---> -7x+12=-9 ---> -7x= 3 ---> x=-3/7
Now you can find y by substituting x: y=-2x+4 ---> y=-2(-3/7) +4 ---> y=
Answer:
I think the answer is (a) triangle as if you slice the traingular prism with perpendicular to the base as if we slice it with cross sectionally
Hope it helps
47 because start at 1 and 3 add the two together and then that is how you get the next number in this sequence . Which is 4+previous nunber which is 3= 7
7+4=11, 11+7=18 11+18=29 , and 18+29=47
Does this help you any
I’m only 70% positive about my answer, but I believe the answer is A) g(x) = |x+4| - 2.
If I’m correct, the numbers on the inside of the absolute marks are an indication of a horizontal shift of the function and you go the opposite direction of the sign. In this case, it’s a shift to the left (looking at the graph, 4) Then the outside number tells you how far you shift vertically (down 2, following the negative sign this time).

The line of symmetry passes through the vertex of the parabola. The x coordinate of the vertex is found with the formula <span>x=−<span>b<span>2a</span></span></span> for the equation of the form <span>y=a<span>x2</span>+bx+c</span>.
In this example, <span>a=1</span>, <span>b=10</span> and <span>c=25</span>
<span>x=−<span>10<span>2⋅1</span></span>=−5</span>
Because the line of symmetry passes through the vertex, the equation of the line is <span>x=−5</span>.
