Answer:
y= -2x-22.
Step-by-step explanation:
1) the slope-interception common form is y=s*x+i, where 's' and 'i' are the slope and interception, unknown numbers;
2) if x₁= -3; y₁= -16, and s=-2, then the equation of the required line can be written in the point-interception form y-y₁=s(x-x₁); ⇔ y+16= -2(x+3);
3) the required equation in slope-interception form is:
y+16= -2x-6; ⇒ y= -2x-22.
note, the provided solution is not the only and shortest way.
Answer:
13 seashells
Step-by-step explanation:
p=number of seashells pierre collected
p+3p=52
4p=52
p=13
13 seashells
Just distribute! its 2/15 - 9/25w
8x-7 = 6x+ 5
2x = 12
X = 6, plug into equation
Y= 6(6) + 5
Y = 41
0 = -16t^2 -60t +54
t = 0.75 seconds
solving by the quadratic equation or graphing calculator or completing the square.
