Step-by-step explanation:
3x - y = 74
4y = x
Replace x in the first expression by 4y
3x - y = 74 ➡ 3(4y) - y = 74
12y - y = 74
11y = 74
y = 74/11 we can use this to find x
4y = x
4 × 74/11 = x
296/11 = x

Answer:
= 0.00334
therefore,
3,872.80 > 0.00334
Step-by-step explanation:
Which statement is correct?
(2.06x102x1.88 x 10-1) <7.69x 10
2.3x10-5
(2.06 x 10-2)(1.88 x 10-1) 7.69x 10-
2.3x10-5
7.69 x 10"
(2.06 x 10-2x1.88x10-)>
2.3x10-5
(2.06x 10-2X(1.88x 10-1)-7.69x104
2.3x10-5
Given that;
= 0.00334
therefore,
3,872.80 > 0.00334
Answer:
Step-by-step explanation:
given are the two following linear equations:
f(x) = y = 1 + .5x
f(x) = y = 11 - 2x
Graph the first equation by finding two data points. By setting first x and then y equal to zero it is possible to find the y intercept on the vertical axis and the x intercept on the horizontal axis.
If x = 0, then f(0) = 1 + .5(0) = 1
If y = 0, then f(x) = 0 = 1 + .5x
-.5x = 1
x = -2
The resulting data points are (0,1) and (-2,0)
Graph the second equation by finding two data points. By setting first x and then y equal to zero it is possible to find the y intercept on the vertical axis and the x intercept on the horizontal axis.
If x = 0, then f(0) = 11 - 2(0) = 11
If y = 0, then f(x) = 0 = 11 - 2x
2x = 11
x = 5.5
The resulting data points are (0,11) and (5.5,0)
At the point of intersection of the two equations x and y have the same values. From the graph these values can be read as x = 4 and y = 3.
