Answer:
10 +11f
Step-by-step explanation:
3(4 + 2f) + 5f - 2 =
12 + 6f + 5f - 2 =
10 +11f
Down payment of the ford pickup truck = $1,900.
It is said that down payment amount $1,900 owes 75% of the selling price.
Therefore, 100-75 = 25% is the downpayment of total Selling price.
Let is assume selling price is $x.
According to problem,
25% of the selling price equals down payment amount $1,900.
Let us convert above statement into an equation.
25% of x is 1,900.
That is 25% x = 1,900.
25% could be written as 25/100 or 0.25.
So, the above equation would become
0.25x = 1,900.
Dividing both sides by 0.25, we get
0.75x/0.25 = 1,900/0.25
x=7600
So, the selling price would be $7600.
Answer:
9, 40 and 41
Step-by-step explanation:
All right triangle have lengths that follow the Pythagorean Theorem (a²+b² = c²). Right triangles have one angle equal to 90°. The two shorter sides form the right angle and the side opposite the right angle is called the hypotenuse.
Using the lengths given, we can use guess and check to see what sum of two sides squared would equal a third side, or just plug them into the equation: a²+b² = c² and see what lengths fit this equation.
I recommend starting with squares you are familiar with:
9² + 40²= 81 + 1600 = 1681
Now, take the √1681 to find the length of 'c', or the hypotenuse:
√1681 = 41
Since these three lengths fit the Pythagorean Theoreom, the would form a right triangle.

(B) y=2x^2
Step-by-step explanation:
(1/2) and (1/4) make the graph wider
2 makes it narrower
Answer:
(y-(-3))=4(x-(-1))
Step-by-step explanation:
formula for point slope form is:
y-y1=m(x-x1)
just plug in numbers from the point (-1, -3) for x1 and y1. The slope 4, would plug into m.
