Answer:
No Solutions.
Step-by-step explanation:
I will solve your system by substitution.
3y−3=3x; −3x+3y=−57
Step: Solve 3y−3=3x for y:
3y−3+3=3x+3 (Add 3 to both sides)
3y=3x+3
(3y/3=3x+3)/3
(Divide both sides by 3)
y=x+1
Step: Substitute x+1 for y in −3x+3y=−57:
−3x+3y=−57
−3x+3(x+1)=−57
3=−57 (Simplify both sides of the equation)
3+(−3)=−57+(−3) (Add -3 to both sides)
0=−60
Answer:
35°
Step-by-step explanation:
set it equal to 180 because the total sum of the interior angles of a triangle is equal to 180
x+x-15+95=180
2x+80=180
2x=100
x=50
now plug it in
50 - 15 = 35
Answer:
All real numbers greater than or equal to -3
Step-by-step explanation:
First look at graph where the line points to which direction of the graph
And look for any closed or open circles in the graph
Since in the graph has a close circle at (-3,-2) meaning it includes that x-value for its domain.
With the graph going to positive infinity it states that the domain is all real numbers.
So in conclusion it has a domain of all real numbers greater than or equal to -3
Answer:
a = h-7
Step-by-step explanation:
h = a+7
Subtract 7 from each side
h-7 = a+7-7
h-7 =a
Answer:
28.56
Step-by-step explanation:
First we need to calculate the mean average of the numbers
Average = 112+89+95+77+103/5
Average = 476/5
Average = 95.2
If Sam made 30% of goals in his last 6 games, then on average, amount made is expressed as;
Average of the last six games = 30% of 95.3
Average of the last six games = 0.3 * 95.2
Average of the last six games = 28.56
Hence the required point average is 28.56
