Answer:
x-intercept: -3
y-int: 2
Step-by-step explanation:
x-intercept is the point where the line crosses the x-axis.
Solve as simultaneous equations or substitute for the x or y value, and then get the other x or y value by substituting.
Substitution method:
y + 4x = -24
x = 3y - 45
Substitute the x into the first equation.
y + 4 (3y-45) = -24
Simplify and solve for y
y + 12y - 180 = -24
13y = -24 + 180
13y = 156
y = 12
Substitute y into one of the equations to find the x value.
x = 3(12) - 45
x = -9
(-9,12) is where the lines intersect.
Answer: Option D. x>=3 or x<=-5
Solution:
3x+4>=13 or 2x-1<=-11
3x+4-4>=13-4 or 2x-1+1<=-11+1
3x>=9 or 2x<=-10
3x/3>=9/3 or 2x/2<=-10/2
x>=3 or x<=-5
