Answer:
The equation is ;
4x - y = 13
Step-by-step explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
from what we are given, let us write the second equation in the general form
x + 4y = 10
4y = -x + 20
y = -1/4x + 20/4
y = -1/4x + 5
mathematically, when two lines are perpendicular, the product of their slope is -1
So for the second line with slope m2
m2 * -1/4 = -1
m2 = 4
So, using the general form, we have the equation as;
y = 4x + b
To get the value of b, we substitute the coordinates of the given point (3,-1)
-1 = 4(3) + b
-1 = 12 + b
b = -1-12
b = -13
So the equation is;
y = 4x - 13 which can be rewritten as;
4x-y = 13
Answer:
24
Step-by-step explanation:
4x + 6 = 102
-6. -6
4x= 96
x=24
Answer:
12
Step-by-step explanation:
length× bredth× height=volume but in this case it is a cylinder so for length and bredth we will use radius. For the height the cylinder is half filled so its height will be 1m. then we will use the formula
l×b×h 3×3×1=9 So 9 is the answer ♥
