Answer:

y = 0

Step-by-step explanation:

subsitute x = -3 into y = x^2 - 7x + 12

y = -3^2 - 7 x  -3 + 12

  = 9 - 21 + 12

  =  0

X(4x-3)=0 <br> A. {-3/4, 0} <br> B. {3/4,0} <br> C.{3/4}
svet-max [94.6K]

Answer:

B. {3/4,0}

Step-by-step explanation:

x(4x - 3) = 0 \\ x = 0 \:  \: or \:  \: 4x - 3 = 0 \\ x = 0 \:  \: or \:  \: x =  \frac{3}{4}  \\ x =   \bigg\{ \frac{3}{4},  \:  \: 0  \bigg\}

What is the point-slope form of the line with slope 5 passing through (4,-2)
poizon [28]

Answer:

y + 2 = 5(x - 4)

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = 5 and (a, b) = (4, - 2), hence

y - (- 2) = 4(x - 4)

y + 2 = 5(x - 4) ← in point- slope form
