To find the perimeter you just multiply the numbers for example
for number one just multiply 4 and 6 which is 24
<h3>Answer: Choice B) </h3><h3>-6x - 2y = 12</h3>
===============================================
Explanation:
The x intercept is (-2,0) which is where the graph crosses the x axis.
The y intercept is (0,-6) which is where the graph crosses the y axis.
-----
Find the slope of the line through those two points
m = (y2-y1)/(x2-x1)
m = (-6-0)/(0-(-2))
m = (-6-0)/(0+2)
m = -6/2
m = -3
-----
The y intercept (0,-6) leads to b = -6
Both m = -3 and b = -6 plug into y = mx+b to get
y = mx+b
y = -3x+(-6)
y = -3x-6
-----
Now add 3x to both sides
y = -3x-6
y+3x = -3x-6+3x
3x+y = -6
-----
Lastly, multiply both sides by -2 so that the "-6" on the right hand side turns into "12" (each answer choice has 12 on the right hand side)
3x+y = -6
-2(3x+y) = -2(-6)
-2(3x)-2(y) = 12
-6x-2y = 12
which is what choice B shows.
Answer:
392
Step-by-step explanation:
28 times 14
or you can take 1 divided by 28 and you should get 0.03571428571428571 then take 14 times 0.3571428571428571 and you should get 39.2 and then just move your decimal place over to the right one place. and your answer will be 392 miles
Answer: Yes it is.
Step-by-step explanation:
Answer:
A, C and D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y - intercept )
here m = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute (- 1, 4) into the partial equation
4 = 3 + c ⇒ c = 4 - 3 = 1
y = - 3x + 1 ← in slope- intercept form → C
Add 3x to both sides
3x + y = 1 ← in standard form → A
-----------------------------------------------------------
The equation of a line in slope- intercept form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = - 3 and (a, b) = (- 1, 4), thus
y - 4 = - 3(x + 1) ← in point- slope form → D
