Answer:
5x+17
Step-by-step explanation:
2(x+7)+3(x+1)
=2x+14+3x+3 you remove the bracket
=2x+3x+14+3 you collect like terms
=5x+17

<em><u>Problem:</u></em> <em> 161.7 </em>÷ <em>7 =
</em>
<em>161.7 rounded to the tenths place is 162.
7 rounded to the ones place is 10. So divide 162 by 10.
</em>
162 ÷ 10 = 16.2
<em>16.2 rounded to the tenths place is 16.
<u>
Answer:</u>
<u /><u /></em><u />So the answer of the estimation is 16.
Answer:
A. one solution; lines intersect at one point
B. (x, y) = (3, 4)
Step-by-step explanation:
A linear equation will be represented on a graph by a straight line. A pair of equations will graph as a pair of lines. If the lines are not coincident or parallel, they will intersect at exactly one point. That point is the solution to the pair of equations.
__
<h3>A.</h3>
A graph of the given points quickly shows the lines are not parallel or coincident. Each point on line A satisfies the equation that describes the line. Each point on line B satisfies the equation that describes line B. The point of intersection is a point that satisfies both equations.
A pair of distinct non-parallel lines can have at most one point of intersection. Hence there can only be one solution to the pair of equations.
__
<h3>B.</h3>
The graph shows the solution to the equations for lines A and B is ...
(x, y) = (3, 4)
Answer:
7.64 × 10 × -10 × -10 × -10
Step-by-step explanation:
7.65 × 10‐^3
7.64 × 10 × -10 × -10 × -10
The 10 is negative because you are repeating the number "10" 3 times, in a negative way.
Hope this helped!
