Answer:
x = 0.462
Step-by-step explanation:
215x = 99.3
x = 99.3/215
x = 0.462
I believe its B
i hope this helps :)
Above the graph
look at them
7x-y <span><</span>3
x-y<span><</span>4
2x-9y>2
4x+7y>3
dashed boundary line means it does't include htat means taat the symbol is < or >
cross out first 2
one way is to graph the lines as equations and shade accordingly
2x-9y>2
y<2/9x+2/9
shade on bottom
4x+7y>3
y>-7/4x+3/9
shade on top
aswer is 4x+7y>3
Y = mx + b is the slope-intercept form of the equation of a line,
where m = slope, and b = y-intercept.
In problems 1 and 3, your equations are written in the y= mx + b form, so you can read the slope and y-intercept directly.
1.
m = -5/2
b = -5
3.
m = -1
b = 3
5.
For problem 5, you need to solve for y to put the equation
in y = mx + b form. Then you can read m and b just like we did
for problems 1 and 3.
4x + 16y = 8
16y = -4x + 8
y = -4/16 x - 8/16
y = -1/4 x - 1/2
m = -1/4
b = -1/2
