Answer:
x=-4
y=1
Step-by-step explanation:
For the given system of equations,
2.5x-3y=-13.....eqn(1)
3.25x-y=-14.....eqn(2)
We first make y the subject of eqn (2)
This implies that,
y=3.25x+14.....eqn(3)
We substitute eqn (3) into eqn (1)
2.5x-3(3.25x+14)=-13
2.5x-9.75x-42=-13
-42+13=9.75x-2.5x
-29=7.25x
Dividing through by 7.25, we obtain
x=-4
We now put the value of x into eqn (2)
3.25(-4)-y=-14
This implies that,
-13+14=y
y=1
Length = 4/5 ft
area = 3/10 ft.
Width = 3/10 ÷ 4/5 ft
= 3/10*5/4 ft
= 3/8 ft
Perimeter = 2(L+W)
= 2(4/5+3/8) ft
= 2(32+15)/40 ft
= 47/20 ft
= 2.35 ft
Answer:
<em>y = -3x + 2</em>
Step-by-step explanation:
From the graph, you see the line intersects the y-axis at y = 2, so the y-intercept is b = 2.
Now we need the slope. We need to find the number of vertical and horizontal units to go from one point to the other. Starting at point (-1, 5), go down 6 units and then go right 2 units. The change in y is -6. The change in x is 2. slope = m = (change in y)/(change in x) = -6/2 = -3.
m = -3; b = 2
y = mx + b
y = -3x + 2
