Well you can graph it by plotting 3 points then drawing a line through these 3 points. The graph will be a straight line . By plotting 3 points you can be more sure if you are right, because if you make a mistake then they might not make a straight line.
Put y = 0 in the equation and find the x coordinate:-
x + 5(0) = -20
x = -20
So we have one point to plot:- (-20,0)
Putting x = 0 we get 5y = -20 so y = -4
Second point:- (0, -4)
Putting x = 5 say we get 4 + 5y = -20 so y = -25/5 = -5
so our 3rd point is (5, -5)
Answer:
Step-by-step explanation:
La cantidad numérica es donde escribes la cantidad del cheque con números/dígitos. Escribe los dólares en forma numérica y luego indica los centavos después del punto decimal. En el ejemplo a continuación, los dólares son ciento veinticinco (125) y los centavos son setenta y cinco (. 75).
Answer:
$3.75
Step-by-step explanation:
Given:
Natalie buys a cooper wire that is 3 feet long.
The cost of the wire is $1.25 per foot.
Question asked:
What is the total cost, in dollars, of Natalie's wire?
Solution:
<u>By unitary method:</u>
Total length of wire = 3 feet
Each foot of wire cost = $1.25
3 feet of wire cost = $1.25 3 = $3.75
Thus, total cost of wire is $3.75
<span>8.5k+7-7.5k=9
first combine like terms </span>8.5k and -7.5k to get 1k or just k
k+7=9
subtract 7 from both sides to isolate k
k = 2
Option D is the correct answer
A triangle’s angles must add up to 180 to be a proper triangle. Option A, B, and C added up all equal 180, whereas option D only equals 150.
