Answer:
4/6
Step-by-step explanation:
a number which means "x" or u can name any variable u want
so the product of a number and four means
X×4
the increased by one or plus one
X×4+1
is at least 7
X(4)+1=7
4x+1=7
4x=7-1
4x=6
x=4/6
i guess so
lemme know if I'm right
Answer:

Step-by-step explanation:
Multiply across.

Answer:

Step-by-step explanation:
Given:
From the graph shown,
The broken line means that the inequality sign will be either < or >.
The shaded region is to the left of the broken line. This means that
.
Now, in order to find equation of line, we need slope and y-intercept.
From the graph, the y intercept is at
. So, y intercept is 1.
Also, if we consider two points
on the line, then slope is given as:
Therefore, the equation of the line is given as:

But as the shaded region is to the left of the line,
∴
is the correct answer.
Answer:1. X=2 y=4
2. X=2.5 y=3
3.x=0 y=-1
Step-by-step explanation:
1. 6x=12
x=2
replace
4+y=8
y=4
2.
8x=20
x=2.5
replace
5+3y=14
y=3
3.
-6y=6
y=-1
replace
x=0
