Parelell lines have the same slope
y=mx+b
m=slope
given
y=-3x+6
slope is -3
so
y=-3x+b is our equation
find b
use (-4,7)
x=-4 and y=7
7=-3(-4)+b
7=12+b
-5=b
y=-3x-5 is da equation
Answer:
the first and third option
Step-by-step explanation:
In the initial recipe, the ratio of tomato sauce to chile sauce is 1 : 3/2
To make it spicier this ratio has to be higher than the initial ratio
Ratio in the first option : 1/2 : 1 = 1 : 2
option 2 : if both recipes are double, the proportion of ingredients remain the same
oprion 3 : 1 : 3
option 4 : 1 : 1
option 5 : 1 : 5/3
K easy 1 change 10 to -10 add it to -30 and get -40 divid -40 by 3.5 and get
x<-11 (if im worng sorry i am in pre algebra not algebra but i am good at math not fractions wet)
Answer:
We kindly invite you to read carefully the explanation detailed below for further details.
Step-by-step explanation:
At first we understand that Diego converted length and wide units from feet to inches () and then he divided each term by 180, since he was using a reduction scale, so that rectangular parking lot can be represented on paper. That is:
Step 1 - Unit conversion:
( - Length)
( - Width)
Step 2 - Applying scaling:
( - Scaled length)
( - Scaled width)
Answer:
The point ( 0,-1) is a solution.
Step-by-step explanation:
y<= (x+1) (x+5)
y>= (x-1)^2 -6
See attached graph.
To prove algebraically, put the point (0,-1) into both equations and see if it is true for both of them.
y<= (x+1) (x+5)
-1 <= (0+1) (0+5)
-1<= 1*5
-1 <=5
True
y>= (x-1)^2 -6
-1 >= (-1)^2 -6
-1 >= 1-6
-1 >=-5
True
The point is a solution
