Which of the following number lines depicts the solution to 4(x+1) > 16 + 7x?
9514 1404 393
Answer:
b) x < -4
Step-by-step explanation:
Eliminate parentheses and you have ...
4x +4 > 16 +7x
-12 > 3x . . . . . . . . subtract 4x+16
-4 > x . . . . . . . . divide by 3
The number line will have an open circle at -4 and be shaded to the left. The pictures are a bit fuzzy, but we think choice B has that description.

If you like my answer than please mark me brainliest thanks
Answer:
x = 7
Step-by-step explanation:
Step 1: Add 6 to both sides.
[tex]3x - 6 + 6 = 15 + 6[/tex] [tex]3x = 21[/tex]Step 2: Divide both sides by 3.
[tex]\frac{3x}{3} = \frac{21}{3}[/tex] [tex]x = 7[/tex]Step 3: Plug in the value to see if it's correct.
[tex]3(7) - 6 = 15[/tex] [tex]21 - 6 = 15[/tex] [tex]15 = 15[/tex]Therefore, x = 7.

HELP ASAP PLS
Answer:
inconsistent, none
Step-by-step explanation:
Write both equations in slope-intercept form to see if the lines are parallel.
These two lines have slope m = −2 and different y-intercepts, therefore they are parallel.
Since the lines are parallel, the system is inconsistent and there are no solutions.
The system of equations 4x + 2y = −8 6x + 3y = 9 is inconsistent and has no solutions.
What is system of Equations?A system of equations is a collection of two or more equations with a same set of unknowns.
We need to write both equations in slope-intercept form to see if the lines are parallel.
4x+2y=-8
2y=-8-4x
y=-4-2x,
y=-2x-4, m₁=-2
and 6x+3y=9
3y=9-6x
y=-2x+3, m₂=-2.
So two lines have slope m = −2 and different y-intercepts,
It means two line are parallel.
Since the lines are parallel, the system is inconsistent and there are no solutions.
Hence 4x + 2y = −8 , 6x + 3y = 9 is inconsistent and has no solution.

Answer : Diluc + Klee = Dlee
write the equation of the graph in slope intercept form
(3,-3) (-3,-5)
m= -4
Answer:
y = -4x + 9
Step-by-step explanation:
Slope intercept form is:
y = mx + b
If m = -4
y = -4x + b
Plug the values of the first set of coordinates into this:
y = -4x + b
-3 = -4(3) + b
-3 = -12 + b
Add 12 to both sides of the equation to isolate b:
-3 + 12 = -12 + b + 12
9 = b
So that makes the slope intercept form:
y = -4x + 9

-22
m=⅓
m=-3
m=3
m=-⅓
Answer: Slope of the line formed by the data is -3.
m=-3 for y=mx+b.
Step-by-step explanation: The slope is the change in y (the rise) divided by the change in x (the run) between two points on the line. I'll pick 2 points: (-4,17) and (9,-22). Any two points will work, if it is a straight line. For these points, y, the rise, changes from 17 to -22, for a net change of (-22 - 17) = -39 for y. x, the run, goes from -4 to 9, for a change in x of (9 - (-4)) = 13.
The rise(y) over the run(x) for these points is thus (-39/13) = -3
The slope is -3
Victor and his friends are preparing for an epic snowball fight. They make 85 snowballs before Victor's dad calls them in for lunch. After lunch, they make more snowballs. In all, Victor and his friends make 153 snowballs.
Which equation can you use to find the number of snowballs s Victor and his friends make after lunch?
Answer:
85+x=153
Step-by-step explanation:
So basically, Victor made an unknown amount of snowballs after lunch, and you need to find the amount. You can represent the unknown as the variable x. Then, you get the equation 85+x=153
The equation used to find the number of snowballs s Victor and his friends make after lunch is s + 85 = 153.
Given data:
Victor and his friends are preparing for an epic snowball fight. They make 85 snowballs before Victor's dad calls them in for lunch. After lunch, they make more snowballs. In all, Victor and his friends make 153 snowballs.
Now , the equation to find the number of snowballs Victor and his friends make after lunch is determined as :
s + 85 = 153
In this equation, "s" represents the number of snowballs they make after lunch. The equation states that the sum of the snowballs made before lunch ("85") and the snowballs made after lunch ("s") is equal to the total number of snowballs they made ("153").
Hence, the equation is s + 85 = 153

A sprinter travels a distance of 100 m in a time of 8.96 seconds.
What is the sprinter's average speed rounded to 4 sf
The average speed is 40.176 Km/h.
What is Average speed?The average speed is the total distance traveled by the object in a particular time interval.
Given:
distance = 100m
time= 8.96 seconds
So,
average speed = distance/time taken
= 100/8.96
= 11.16 m/s
and in Km/h
= 11.16* 18/5
= 40.176 Km/h
Hence, the average speed is 40.176 Km/h.
