The equation f a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given the point (-3,7) and slope m=4
y-7=4(x-(-3))
y-7=4(x+3)
solve for y
y-7=4x+12
add 7 both sides
y=4x+19
B is answer
Answer:
x=9
Step-by-step explanation:
-4|x-3| = -16
-4+x-3 = -16
-7+x = -16 (add -4 and -3)
x = -16+7 (add -7 to -16)
x=9
0.75n + 2 = t
The passenger is charged $0.75 per/for a number of miles(n) plus a fee of $2, and the total cost of the ride is t.
Answer:72
Step-by-step explanation:Given : A cone has a diameter of 18 units and height of 8 units.
We have to determine the volume of the given cone.
We know Volume of cone = 1/3
Where r is radius of cone
h is the height of cone
Given : diameter = 18units so, radius is half of diameter = 9 units
height = 8 units
Substitute, we have,
Volume of cone = 1/3 
Simplify, we have,
Volume of cone = 
Thus, the volume of given cone is 72π cubic units.
1. System B from System A by replacing one equation with itself where the same quantity is added to both sides
2. Yes, both system A and system B are equivalent and therefore has the same solution
<h3>How to prove the statements</h3>
System A
x − 4y= 1
5x + 6y= −5
System B
x = 1+4y
5x + 6y= −5
1. System B can be gotten from system A by
from the first equation of A
x − 4y= 1
Make 'x' subject of formula
x = 1 + 4y
This makes it equal to tat of system B
Thus, replacing one equation with itself where the same quantity is added to both sides
2. System A
x = 1 + 4y
5x + 6y= −5
System B
x = 1 + 4y
5x + 6y= −5
From the above equations, we can see that both system A and system B are equivalent and therefore has the same solution.
