Answer:

D. y = -4x - 6

Step-by-step explanation:

→ Work out gradient of line

$\frac{2-6}{-2--3} =\frac{-4}{1} =-4$

→ Write into y = mx + c format

y = -4x + c

→ Substitute ( -2 , 2 ) into the equation to find c

2 = 8 + c

→ Minus 8 from both sides

-6 = c

→ Write full equation y = -4x - 6

General form of the equation of a circle with its center at (-2, 1) and passing through (-4, 1)

jonny [76]

hello :
an equation of the circle Center at the A(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : a = -2 and b = 1 (Center at the A(-2,1))
r = AP......P( -4 , 1)
r² = (AP)²
r² = (4+2)² +(1-1)² = 36
an equation of the circle that satisfies the stated conditions.
Center at A(-2,1), passing through P(-4, 1) is : (x+2)² +(y-1)² = 36

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 55 p

Natali [406]

Answer:

Large boxes = 40 lbs.

Small boxes = 15 lbs.

Step-by-step explanation:

L = Large Box

S = Small Box

I started by making the equations, L + S = 55 and 60L + 50S = 3150. I made the first equation L = 55 - S and substituted that in for L in 60L + 50S =3150. After finding S, I plugged that back into L + S = 55 and got the answers.
