Answer:
<h2>- 2</h2>
Step-by-step explanation:
The slope intercept form of an equation of a line:
m - slope
b - y-intercept
We have the equation of a line in the standard form
Convert to the slope-intercept form:
<em>subtract 4x from both sides</em>
<em>divide both sides by 2</em>
Therefore the slope is equal to -2.
Other method:
If we have the equation of a line in standard form Ax + By = C
or in general form Ax + By + C = 0, then the formula of a slope is
We have A = 4 and B = 2. Substitute:
9514 1404 393
Answer:
(x, y) = (2, 5)
Step-by-step explanation:
Substitute the expression for y in the second equation into the first equation:
5x -5 = x +3
4x = 8 . . . . . . add 5-x to both sides
x = 2 . . . . . . divide by 4
y = 2+3 = 5 . . . substitute for x in the first equation
The solution is (x, y) = (2, 5).
Answer:
AB = 3.5 cm
Step-by-step explanation:
The error was the 2 numbers being switched. Instead of 1 - 4.5, the correct calculation should be 4.5 - 1 which equals 3.5
1.06 is less because in the tenths place obviously, 6 is greater then 0 so 1.6 would be greater. It is incorrect because in the tenths place again, 7 is greater than 1 so there u go.
Answer:
Fiona cannot go on the field trip
Step-by-step explanation:
6.5 x 6 = 49
5.25 x 2 = 10.5
49 + 10.5 + 10.5 = 60
