Answer:
y = x² + 6x + 8
Step-by-step explanation:
The zeros ( x- intercepts ) of the graph are x = - 4 and x = - 2, thus
the factors are (x + 4) and (x + 2) and the function is the product of the factors.
y = a(x + 4)(x + 2) ← a is a multiplier
To find a substitute (0, 8 ) the y- intercept into the equation
8 = a(0 + 4)(0 + 2) = a(4)(2) = 8a ( divide both sides by 8 )
a = 1, thus
y = (x + 4)(x + 2) ← expand using FOIL
= x² + 6x + 8
Answer:
x = 30
Step-by-step explanation:
The two angles add to a right angle which is 90 degrees
30 +2x = 90
Subtract 30 from each side
30 +2x - 30 =90-30
2x= 60
Divide each side by 2
2x/2 = 60/2
x = 30
You do
-26
-4
---
-30
5n=-30 so...
-30/5=-6
Therefore
n=-6
Answer:
<h2>
7°</h2>
Step by step explanation
We know that the diagonals of a square bisects it's angles and every angles of square are 90°
m<BCD = 90°
m<BCA = m< DCA = 4x + 17
m<BCA + m<DCA = m <BCD
4x + 17 + 4x + 17 = 90
4x + 4x + 17 + 17 = 90
8x + 34 = 90
8x = 90 - 34
8x = 56
X = 56/8
x = 7
Hope this helps...
Good luck on your assignment...
Answer:
8.75 tons
Step-by-step explanation:
3500 pounds to tons is 1.75 so 1.75 tons x 5 cars= 8.75 tons.
