Answer:
y = - 7x - 26
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 7, thus
y = - 7x + c ← is the partial equation of the line
To find c substitute (- 5, 9) into the partial equation
9 = 35 + c ⇒ c = 9 - 35 = - 26
y = - 7x - 26 ← equation of line
Answer:
d. y = (x +2)(x -3)
Step-by-step explanation:
When p is a zero of the function (an x-intercept), the function has (x -p) as a factor.
Here, the x-intercepts are x = -2 and x = 3. This means the factors of the function are (x -(-2)) = (x +2) and (x -3).
y = (x +2)(x -3)
Hello.
The answer is: In a perfect square trinomial, two of your terms will be perfect squares.
Perfect squares are numbers or expressions that are the product of a number or expression multiplied to itself. 7 times 7 is 49, so 49 is a perfect square. x squared times x squared equals x to the fourth, so x to the fourth is a perfect square.
Have a nice day
Answer:
a) 20 units
b) 2 √10 units
c) 2 √17 units
Step-by-step explanation:
The distance formula is;
D = √(y2-y1)^2 + (x2-x1)^2
a) D = √(-7-9)^2 + (-7-5)^2
D = √256 + 144
D = √400
D = 20
b) D = √(10-8)^2 + (9-2)^2
D = √(2)^2 + 6^2
D = √4 + 36)
D = √40
D = 2 √10 units
c) D = √(1 + 7)^2 + (-8+10)^2
D = √(64 + 4)
D = √68
D = 2 √17 units
