Answer:
3x+5≥7
3x≥7-5
3x≥2
x≥⅔
interval notation: [⅔; +infinity[
Let me know is your inequation is 3x+5>-7.
if it's not this ≥ then let me correct.
thanks
Answer:
-9.7
Step-by-step explanation:
we can do the opposite of everything that was done to get the resulting difference
so......
-8.4+6.4=-2
-2x19.4=-38.8
-38.8/4=-9.7
and to double check.......
-9.7x4=-38.8
-38.8/19.4=-2
-2-6.4=-8.4
Answer:
1) 5/7
2) (21, 5)
Step-by-step explanation:
1) The slope of the line passing through the points (7, 5) and (21, 15) is
because slope is (difference of y)/(difference of x)
the first option is correct
2) 1/3 of 5/7 is 5/21.
The line will be in the form of
y = 5/21 x + b where b is the y-intercept.
Find the complete equation by plugging in (0,0) since it passes thorugh the origin.
0 = 5/21 (0) +b
0=0+b
b=0
The equation: y=5/21 x
let's check each option by plugging in.
y= 5/21 (3)= 5/7
y is not 5 but 5/7
y= 5/21 (3)= 5/7
y is not 7 but 5/7
y= 5/21 (21) = 5
y is 5, which matches with the answer choice!!!
y= 5/21 (21) = 5
y is 5, not 7.
The third option is correct
