four times a number x is at least -12
an inequality is ?
the solution is ?
Answer:
-16
Step-by-step explanation:
im just taking a guess.
x+4>-12
-4 -4
---------------
4's cancel out and -12+-4=-16
Again this is just a guess.
The inequality is 4x ≥ -12 and the solution of this inequality is x ≥ -3.
What are Inequalities?Inequalities are the expressions having two sides connected with inequality symbols. Inequality symbols are <, >, ≤, ≥ and ≠. They may contain one or more variables and constants.
Inequalities which consist of one or more variables with the highest degree of the variables being 1 is called Linear inequalities.
Given that four times a number is at least -12.
Thus the inequality says that 4 multiplied with a number x, which is 4x has values -12 or greater than -12.
So the inequality is 4x ≥ -12.
Solving this,
4x ≥ -12
Dividing both sides by 4, we get,
4x/4 ≥ -12/4
x ≥ -3
Hence the inequality is 4x ≥ -12 and the solution is x ≥ -3.

ITS NOT A OR B!!!! WILL GIVE BRAINLIEST!!!!!!Mia looked at a graph showing average global temperatures. She noticed that the average temperatures have risen abruptly over the past several decades. This indicates that global warming is occurring at a fast rate. What additional pieces of evidence do scientists use to support the idea that global warming is happening?
the amount of greenhouse gases leaving the atmosphere and increases in amounts of sea ice
the greenhouse effect and reductions in sea levels
greenhouse gas concentrations, decreases in amounts of sea ice, and increases in sea levels
ocean temperature changes, greenhouse gases concentrations, and harmful emissions reductions
B
but it could be C
put B
The additional pieces of evidence do scientists used to support the idea of global warming are greenhouse gas concentrations, decreases in amounts of sea ice, and increases in sea levels. Thus, option C is correct.
What is Global warming?Global warming is a type of climate change that refers to the long-term rise in global temperatures.
The concept that global warming is occurring is backed by rising greenhouse gas concentrations, decreasing sea ice, and rising sea levels.
The inability of reflected solar energy to go back to the area as a result of greenhouse gases creating a blanket over the atmosphere is said to be the cause of global warming.
Thus, a rise in greenhouse gas concentrations correlated with an increase in global temperature is one bit of evidence used to support the concept of global warming.
Furthermore, it seems natural that rising global temperatures will cause sea ice to melt and the ensuing water to rise. Hence, option C is correct.

i need help please
Answer:
1/2 or 2
Step-by-step explanation:
If the original triangle length of Side A to C is 4, then the answer is two. If the original traingle length is Side A to C on the original triangle is 8, then the answer is 1/2.
The scale factor of the dilation is 1/2.
What is scale factor?Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given:
Before dilation
AC= 8, BC= 10 abd AB= 6
After dilation
AC= 4, BC= 5 and AB= 3
Now, scale factor
Scale factor = Dimensions of the new shape / Dimensions of the original shape.
So,
scale factor = 4/8 or 5/10 or 3/6 = 1/2
Hence, the scale factor is 1/2.

7. Jon's car averages 20 mpg in town and 28 mpg on the road. What is the percent of decrease between the two driving conditions?
Answers:
1)10.80/12 =0.90
0.90+0.75=1.65
2)252/7=36 units
3)cost price = $9.25*225
= $2081.25
Selling price = $15.75*225
= $3543.75
Profit = Selling price - cost price
Profit = $3543.75 - $2081.25
=$1462.50
5) FV = L*(1 + rt),
Where FV is the amount to repay; L is the borrowed amount (the loan amount) and "r" is the annual interest as decimal; t is the time.
In your case L = 2400 dollars; r = 8% = 0.08 (as decimal) and t = 0.5 of a year (6 months).
