Answer: Albert's grand father is 50 years older that Albert this year.
Step-by-step explanation:
Let x represent Albert's age this year.
Let x represent Albert's grandfather age this year.
This year Albert and his grandfather's ages total to 64 years. This means that
x + y = 64- - - -- - - - - -1
In 3 years, Albert's grandfather will be 6 times as old. This means that
y + 3 = 6(x + 3)
y + 3 = 6x + 18
y = 6x + 18 - 3
y = 6x + 15
Substituting y = 6x + 15 into equation 1, it becomes
x + 6x + 15 = 64
7x = 64 - 15 = 49
x = 49/7
x = 7
y = 6x + 15 = 6 × 7 + 15
y = 57
The difference between their ages is 57 - 7 = 50 years
We are asked to find the graph of the function
. When we graph it, we get something like the image attached below. We can see that the one of the curves intersect the y-axis at
, and the only graph that showcases that is the
fourth graph. Hope this helps and have a great day!
F(x)......ur output = 19
19 = 2x^2 + 3x + 5
2x^2 + 3x + 5 - 19 = 0
2x^2 + 3x - 14 = 0
(2x + 7)(x - 2) = 0
2x + 7 = 0
2x = -7
x = -7/2
x - 2 = 0
x = 2
I believe there is 2 possible answers......x (ur input value) = -7/2 or 2
Answer:
Step-by-step explanation:
<u>Area Of A Cube
</u>
Suppose a cube with side length s, the area of one side is
Since the cube has 6 sides, the total area is
But if we have the area, we can solve the above formula for s to get
We have two different cubes with areas 1,200 square inches and 768 square inches. Let's compute their side lengths
The difference between them is
The side of the cube with area 1,200 square inches is 
longer then the side of the cube with area 768 square inches
