Answer:
Therefore the equation of the line through ( -2 , -7 ) and ( 5 , 7 ) is
2x - y = 3
Step-by-step explanation:
Given:
Slope = 2 = m ( say )
Let,
point A( x₁ , y₁) ≡ ( -2 , -7 )
point B( x₂ , y₂) ≡ ( 5 , 7 )
To Find:
Equation of Line AB =?
Solution:
Equation of a line passing through Two points A( x₁ , y₁) and B( x₂ , y₂)is given by the formula,

Or
Equation of a line passing through a points A( x₁ , y₁) and i having slope m is given by the formula,

Substituting the given values in a above equation we get

Therefore the equation of the line through ( -2 , -7 ) and ( 5 , 7 ) is
2x - y = 3
A "regular quadrilateral" is a square, so the length and width are both 4 cm. The surface area of a rectangular prism is given by
S = 2(LW +H(L +W))
S = 2((4 cm)*(4 cm) +(6 cm)*(4 cm +4 cm))
S = 2(16 cm² +48 cm²)
S = 2*64 cm² = 128 cm²
The surface area of the prism is 128 cm².
Answer:
growth
Step-by-step explanation:
This is of the form
y = ab^x where a is the initial value and b is either growth or decay
if b > 1 then it is growth
b <1 it is decay
a = .2
b = 4
Since b>1 it is growth
Answer:
nickels=13 and pennies=15
Step-by-step explanation:
0.05n+0.01p=0.80
-0.01(n+p=28)
0.05n+0.01p=0.80
-0.01n-0.01p= -0.28
0.04n=0.52
n=13
p=15
Answer:
The equation would be x^2 + y^2 = r^2
Step-by-step explanation:
This is the base form of any circle. In this case, you would need the value of the radius to finish the equation.
