Answer:
y = -3x + 2
Step-by-step explanation:
The linear equation is in the form
y = mx + b
where m is the slope and b is the y-intercept
the slope can be calculated using two points
Let us have; (-2,8) and (0,2)
The equation of the slope is ;
m = (y2-y1)/(x2-x1) = (2-8)/(0+2) = -6/2 = -3
So for the y-intercept, we select any of the points to substitute
Let us have (0,2)
Substitute this into;
y = -3x + b
2 = -3(0) + b
b = 2
So the equation is;
y = -3x + 2
You set it up as fractions 4/5 = 28/x and solve for x then add the numbers together. 5*28=140 140/4= 35 35+28= 63
Answer:
Step-by-step explanation:
ɸ = (1+√5)/2
The dimensions of the garden are either 5 ft by 5ɸ ft,
or 5 ft by 5/ɸ ft.
If the length is the shorter dimension, then the width is 5ɸ.
5ɸ ≅ 8.1 ft
If the length is the longer dimension, then the width is 5/ɸ.
5/ɸ ≅ 3.1

Answer:
x-7
Step-by-step explanation:
7x - 18 = 10x + 3
Subtract 7x from each side
7x-7x - 18 = 10x-7x + 3
-18 = 3x+3
Subtract 3 from each side
-18-3 = 3x
-21 = 3x
Divide by 3
-21/3 =3x/3
-7=x
