Answer:
A= x=5 or x=-2
Step-by-step explanation:
x^2-3x-10=0
Factor
What 2 numbers multiply together to give you -10 and add together to give you -3
-5*2 = -10
-5+2 = -3
(x-5) (x+2) =0
Using the zero product property
x-5 =0 x+2 =0
x-5+5=0+5 x+2-2=0-2
x=5 x=-2
Ets see if the gallon fill the paint tray or not.
For that purpose we need to find out the volume of the paint tray and compare it with the volume of the gallon.
Given:
Length = 14 inches
Width = 10 inches
Depth = 4 cm = 1.57 inches
Volume = length x width x depth
Volume = 14 x 10 x 1.57
= 220.47 inches cube
Volume of Gallon = 231 inches cube
Comparing the two volumes:
231 inches cube - 220.47 inches cube = 10.52 inches cube
Hence,

Answer:
y = 3x + 4
Step-by-step explanation:
We can use the equation y = mx + b to find the equation:
Plug in the slope and the point into the equation, and we can find b:
-5 = 3(-3) + b
-5 = -9 + b
4 = b
Now, we can plug in the slope and y-intercept into the equation:
y = 3x + 4 will be our equation
