Answer:
(-5, -2)
Step-by-step explanation:
3x+4y=-23
x=3y+1
since we have what x is, we need to subsitute
3( 3y+1) + 4y= -23
no we need to multiply the number inside the parenthesis by 3
9y + 3 + 4y= -23
combine like terms ( add the numbers or variables that look alike)
9y+4y is 13y
13y+3= -23
since we need to get the y alone we need to subtract 3 on both sides since its the opposite of adding
13y+3-3=-23-3
13y= -26
now we divide 13 on both sides to get Y alone
13y/13= -26/13
y= -2
now since we have y we need to substitute it to find x
x= 3y+1
x= 3( -2) +1
now we mutliply 3 with -2
x= -6 +1
x=-5
those are ur answers
y= -2
x= -5
hope this helped:D
Independent variables are the variables that can change on their own.
Dependent variables are the ones that change as a result.
If we study how long students study on a test and show how much that affects their grade, then the amount of time they study would be the independent variable. It changes on it's own based on the student's preference. The test scores would be the dependent variable because it changes with the amount the student studies.
0.35x7=2.45. The river's height decreases by 2.45 inches after 7 days
Answer:
x = 33°
Step-by-step explanation:
sin x = 6/11
sin x = o.5455
x = 33°
To simplify 75/54, we first need to find the greatest common factor. Our GCF is 3, so we will divide both number by 3. 75/3=25, and 54/3=18.
75/54 simplifies into 25/18 or 1 7/18
