Answer:
y+2x=7 (1)
x=3+y (2)
Replace x = 3+y (2) into (1) => y+2(3+y) = 7
=> y = 1/3 and x = 3+1/3 =10/3
Step-by-step explanation:
4(3x -1)²
= 4(9x² - 6x + 1)
= 36x² - 24x + 4 (Answer D)
Answer:
x = 128
Step-by-step explanation:
x*(-8) = -16. multiply both sides by -8 to get x by itself
x = 128

y = - 4x + - 8 is equation of slope-intercept form.
What is in slope-intercept form?
- Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form.
- Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.
the equation of slope - intercept form
y = mx + c
( -1 , -4 ) is point shown in graph
slope = -y/x
= - ( -4)/-1 = 4/-1 = -4
- 4 = -4 * - 1 + c
- 4 = 4 + c
c = - 4 - 4 = - 8
put value of c in the equation of slope - intercept form
y = - 4x + - 8
