Answer:

Step-by-step explanation:

Since we are given that f(x)=1, we just have to find what value of x gives 1 as the result.

From the graph, we can see that (0,1) gives 1 as a y-value. Thus, when x is 0, y is 1.

Therefore, f(0)=1.

So, our answer is B.

And we're done!

A gardener is planting two types of trees: Type A is 8 feet tall and grows at a rate of 3 inches per year. Type B is 7 feet tall

777dan777 [17]

Answer:

Exactly 12 years it will take for these trees to be the same height

Step-by-step explanation:

Slope intercept form: An equation of line is in the form of $y = mx+b$ where m is the slope or unit rate and b is the y-intercepts.

Let x represents the time in years and y represents the height of the tree.

Use conversion:

1 ft = 12 inches

As per the given statement:

Type A is 8 feet tall and grows at a rate of 3 inches per year.

⇒unit rate per year = 3 inches = $\frac{1}{4}$ ft

Then, we have;

$y =\frac{1}{4}x + 8$ ......[1]

Similarly for;

Type B is 7 feet tall and grows at a rate of 4 inches per year.

⇒unit rate per year = 4 inches = $\frac{1}{3}$ ft

then;

$y =\frac{1}{3}x + 7$ .....[2]

To find after how many years it will take for these trees to be the same height.

Since, trees to be the same height;

⇒equate [1] and [2], to solve for x;

$\frac{1}{4}x + 8 = \frac{1}{3}x +7$

Subtract 7 from both sides we get;

$\frac{1}{4}x + 8-7= \frac{1}{3}x +7-7$

Simplify:

$\frac{1}{4}x + 1= \frac{1}{3}x$

Subtract $\frac{1}{4}x$ from both sides we get;

$1= \frac{1}{3}x-\frac{1}{4}x$

Simplify:

$1 = \frac{x}{12}$

Multiply both sides by 12 we get;

x = 12

Therefore, exactly it will take for these trees to be the same height is, 12 years

1/3 rd part of the length of a bamboo is coloured in red and 1/5th part of it is coloured green and the remaing is 14m is colour

aksik [14]

$\bold{\huge{\blue{\underline{ Solution }}}}$

$\bold{\underline{ Given :- }}$

1/3rd part of the length of a bamboo is coloured with red and 1/5th part of it is coloured with green and the remaining is 14m is coloured with yellow.

$\bold{\underline{ To \: Find :- }}$

We have to find the total length of the bamboo

$\bold{\underline{ Let's \: Begin :- }}$

Let the total length of bamboo be x

According to the question, 

$\sf{\dfrac{ 1}{3}}{\sf{x +}}{\sf{\dfrac{ 1}{5}}}{\sf{x + 14 = x }}$

$\sf{\dfrac{ 1}{3}}{\sf{x + }}{\sf{\dfrac{1}{5}}}{\sf{x = x - 14 }}$

$\sf{\dfrac{5x + 3x}{15}}{\sf{ = x - 14 }}$

$\sf{ 5x + 3x = 15( x - 14 )}$

$\sf{ 8x = 15x - 210 }$

$\sf{ 210 = 15x - 8x}$

$\sf{ 7x = 210 }$

$\sf{ x = }{\sf{\dfrac{ 210}{7}}}$

$\sf{\red{x = 30\: m}}$

Hence, The total length of the bamboo is 30m.
