Answer:
y=3/5x+3
Step-by-step explanation:
The y-intercept which is the (+3) is taken from where the line crosses the y-axis.
The slop is found from rise over run, in this case, -5 to 0 is positive 5 this would go in the denominator, because we go from solid ground 0 to 3 without crossing another solid point, the numerator is 3.
3t shirts cost $18
1 shirt will cost 18/3t = 6/t
7t shirts will then cost = (6/t)*7t = 42
7t shirts will cost $42.00
Answer:
y = 19 (3)x
Explanation:
y = abx
Plug in the numbers from the 2 given points to find a and b.
19 = ab0 = a
a = 19
171 = 19b2
b = 3
y = 19 (3)x
Answer:
Step-by-step explanation:
We know that a triangle equals to 180 degrees.
(2x+24)+(4x+43)+(x^2+1)=180
the awnser to this is x=8.
You plug in 8 into x
Angle 1: 2(8+24) --> 40
Angle 2: 4(8+43) -->75
Angle 3: (8^2+1) -->65
Check your work: add values together 40+75+65=180
