Answer:
0.375
Step-by-step explanation:
1.y=2x-1
2.y=-x+2
using substitution method
1.y=2x-1
y+1=2x
the other equation where there is an <em><u>x </u></em><em><u>will </u></em><em><u>be </u></em><em><u>replaced </u></em>by a <em><u>the </u></em><em><u>first </u></em><em><u>equation</u></em>
so
2.y=-(y+1)+2
y=-y-1+2
y=-y+1
y+y=1
2y=1
2y/2=1/2
y=0.5
the value of y is <em><u>0</u></em><em><u>.</u></em><em><u>5</u></em> the value of x would be found by <em><u>taking </u></em><em><u>the </u></em><em><u>y </u></em><em><u>and </u></em><em><u>replacing</u></em><em><u> </u></em><em><u>it </u></em><em><u>with </u></em><em><u>0</u></em><em><u>.</u></em><em><u>5</u></em><em><u> </u></em><em><u>in </u></em><em><u>any </u></em><em><u>of </u></em><em><u>questions</u></em><em><u> </u></em><em><u>one </u></em><em><u>and </u></em><em><u>two.</u></em>
1.y(0.5)=2x-1
0.5=2x-1
0.5+1=2x
1.5=2x
1.5/2=2x/2
0.75=x
the value of <em><u>y </u></em><em><u>is </u></em><em><u>0</u></em><em><u>.</u></em><em><u>5</u></em> and <em><u>x </u></em><em><u>is </u></em><em><u>0</u></em><em><u>.</u></em><em><u>7</u></em><em><u>5</u></em>
<em><u>0</u></em><em><u>.</u></em><em><u>5</u></em><em><u>*</u></em><em><u>0</u></em><em><u>.</u></em><em><u>7</u></em><em><u>5</u></em><em><u>=</u></em><em><u>0</u></em><em><u>.</u></em><em><u>3</u></em><em><u>7</u></em><em><u>5</u></em>

Ur graph.....u have a line that has a y int of -2....it has a slope of 3....it has a solid line...so there is no equal sign...it is shaded above the line, so it is greater then.....y > = 3x - 2
u have another line that has a y int of 2....it has a slope of -1/2....it has a solid line...so there is an equal sign in the problem...it is shaded below the line...so it is less then....
y < = -1/2x + 2
1/2x + y < = 2...multiply by 2
x + 2y < = 4
so ur answer is : y > = 3x - 2 and x + 2y < = 4...the 2nd one
The temperatures can be plotted and labelled on a number line as shown in the image attached below (see attachment).
Temperature can be represented on a vertical number line with 0 representing 0°F.
Temperatures above 0°F will be located above 0, while temperatures below 0°F will be located below 0.
Given the following temperatures: <em>-3.5℉
, 5℉, 1.5℉, -0.5℉, -2℉, 2.5℉ and -4℉</em>
Therefore, the temperatures can be plotted and labelled on a number line as shown in the image attached below (see attachment).

Answer:
it doesn't exist
Step-by-step explanation:
the expression 0×7/11 is equivalent to 0. 1/0 isn't possible, so its reciprocal doesn't exist.
