Answer:
X= -1
Y= -3
Step-by-step explanation:
y=-5x-8
y=4x+1
-5x-8=4x+1
+5x. -1 +5x -1
-9=9x
-1=x
Y=4(-1)+1
-4+1
Y=-3

Answer:
C, 4.82
Step-by-step explanation:
add the given lengths and subtract it from the total lengths to get 4.82
Answer: 30
Step-by-step explanation: 6 factors as 3 × 2 and 5 doesn't factor. When finding the least common multiple, we're looking for factors that match up and here we have no factors that match up. This means that our least common multiple or <em>lcm</em> is simply 3 × 2 × 5 or 6 × 5 which is 30.
Answer:
The bottom right graph is correct, with the y-intercept at -3 and the graph shaded to the right.
Step-by-step explanation:
The inequality of y < 4x - 3 is written in slope-intercept form (y = mx + b), where m = slope and b = y-intercept. The difference between a linear equation and linear inequality is that an equation only produces one answer while an inequality and can have several answers. Because the y-intercept = -3, the graph should cross the y-axis at -3, which it does for all the given graphs. However, the slope is 4, which means that the change in 'y' over the change in 'x' is 4/1 - up four units and to the right one unit. This would give us the choice of the bottom to graphs.
Since the inequality is y < 4x - 3, then all answers must be less than the total value of the expression, which means we shade to the right of the line.
