Answer:
solution = 128
Step-by-step explanation:
if x = 6 , y = -4
then,
- ( 3 × 6 × 6 ) - ( 5 × -4 )
- 108 + 20
- 128
r=- 3/8 cos (0)x t maybe is this
X = -3/2 and is first degree
Answer:
Step-by-step explanation:
To find the gradient of a line we first hv to find the formula
so Gradient=√X1-x2and √y1-y2
((-2,1) and (0,-5)) line 1
line 2(0,-1) and (1,0)
first we will work for line 1
X1 is -2
X2 is -0
Y1 is 1
Y2 is -1
so y=x-1
so we substitute the values
1--1=-2--0
so,
1+1=-2+0
2=-2
-0
So the equation 1 line 1 is not true
we will now go to equation 2 line 2
the equation is 3x+y=-5
we substitute the values
3(-2--0)+1--1=-5
3(-2)+-2=-5
-6+-2=-5
-8= -5
group like terms
Ur answer should look like this -3
So the answer is 3x+y=-5
