Answer: 1 year

Step-by-step explanation:

1. Make an equation for both Types in standard y = mx + b form, with “b” being how tall the tree already is (so b for Type A will be 9, and b for Type B will be 2). Let “m” be equal to how many inches each tree grows per year (m for Type A will be 17, m for Type B will be 24)

2. Now you have the equations!
Type A: y = 17x+9
Type B: y = 24x+2

3. The problem is asking for how many years (represented by “x”) it will take for the trees to be of equal height, so set both of the equations equal to each other
17x+9 = 24x+2

4. Solve! (picture attached)
I hope this helped! feel free to comment if you need any clarification, though!

Answer:

12 years

Step-by-step explanation:

A = 9 ft = 108 inch

B = 2 ft = 24 inch

So, (108 - 24) = 84 inch

A 9 ft - B 2 ft = 7 ft distance

84 inch ÷ 7 feet = 12 it will take 12 years

A = 17 inch × 12 years + 108 inch = 312 inch or 26 ft

B = 24 inch × 12 Years + 24 inch = 312 inch or 26 ft

10 Points + BRANIEST

S_A_V [24]

Answer:

Step-by-step explanation:

So, we’re probably looking at a n9-m0 cusp, since adding 0 to a number gives a sum lower than adding 9 to a slightly smaller number, something that isn’t true elsewhere in the cycle.

We need a n9 where the sum n+9 is divisible by 3. 9 is divisible by 3 already, so n must be divisible by 3 as well. So, it’s 0, 3, 6, or 9.

Taking as the most likely 3 (because a 39 year old is more likely than a 9 year old, 69 year old, or 99 year old to have a child who doesn’t already know their father’s age) we’ll try 39, 40. 3+9=12, 4+0=4, 12/3=4, this is a possible solution.

Do the others work?

0+9=9, 1+0=1, 9/4=/=1

6+9=15, 7+0=7, 15/4=/=7

9+9=18, 1+0+0=1, 18/4=/=1

1+2+9=12, 1+3+0=4, 12/3=4

there are at least two possibles. the father was correct, the father cannot determine his age from what she has been told, she must guess. From what she knows of him, is it more likely that he’s 39, or 129, or even older?

Seven times the sum of a number and 1 is 28.

lisabon 2012 [21]

The number in the question that gives 28 after the operations is; <em><u>3</u></em>

We are told that the product of seven and the sum of a number and 1 is 28.

Let the number be x. Thus;

7(x + 1) = 28

Use division property of equality to divide both sides by 7.

7(x + 1)/7 = 28/7

(x + 1) = 4

Use subtraction property of equality to subtract 1 from both sides to get;

x + 1 - 1 = 4 - 1

x = 3

Therefore, in conclusion the number is 3.

One factor of the function f(x) = x3 − 6x2 + 11x − 6 is (x − 3)

arlik [135]

Let f(x)= y = x3 - 6x2 + 11x - 6
X intercept means a point on the graph which intercepts the x axis
And Y-intercept mean a point on the graph which intercepts the y axis
Meaning at the x intercept the component of y is zero because there is no y on the x axis

And at the y intercept the x component of the coordinate is zero because on the y axis there is no x value
So in finding the y intercept of the graph wherever u see x place zero there (ie x= 0 on the y axis)
So with x = 0
y = (0)3- 6(0)2 + 11(0) - 6
y = -6

Therefore the y intercept is (0,-6) in coordinate form or -6

X-intercept
y = x3 - 6x2 + 11x - 6
After factorization and simplification
y = (x-1)(x-2)(x-3)
On the x axis y= 0
0= (x-1)(x-2)(x-3)
Either x-1=0
x=1
(1,0)
Or x-2=0
x=2
(2,0)
Or x-3=0
x=3 (3,0)
Therefore the x intercepts are 1,2 and 3
And they are expressed in coordinate form as (1,0) ,(2,0) and
(3,0)
