Answer:

t > 28

Step-by-step explanation:

Given

[tex]\frac{t}{4}[/tex] > 7 ( multiply both sides by 4 to clear the fraction )

t > 28

Answer:

24

Step-by-step explanation:

[tex]\frac{4}{6} =\frac{x}{36}[/tex]

[tex]\frac{4}{6} *\frac{6}{6} =\frac{24}{36}[/tex]

[tex]x = 24[/tex]

Answer: (3,1)

Step-by-step explanation:

2x + 3y = 9

(x + 5y = 8) -2

2x + 3y = 9

An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression 2a+b when the value of a is 5 and b is 4  is equal to 14.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given the expression 2a+b, whose values are needed to be calculated when the value of a is 5 and the value of b is 4. Therefore, the value of the given expression 2a+b can be written as,

2a + b

Substitute the value of a and b,

= 2(5) + 4

= 10 + 4

= 14

Hence, the value of the expression 2a+b when the value of a is 5 and b is 4 is equal to 14.

Step-by-step explanation:

Answer:

The equation for the nth term will be;

An = 10 + 2n

After the 9th planter ( 8 more than the initial one); number of trees will be 28

Step-by-step explanation:

After the first person plant two trees, there were 12 trees at the plant sites

What this mean is that initially, they were 12-2 = 10 trees at the plant site

The nth term of the sequence which represents the number of trees given the number of persons that have planted will be;

An = 10 + 2n

Now, after 8 more people planted, since we had one that already planted, the total number of planters is now 9 planters

So using the equation, n will be 9

So ; A9 = 10 + 2(9)

A9 = 10 + 18

A9 = 28

Answer:

$46.10

Step-by-step explanation:

Answer:

Step-by-step explanation:

y = f(x)

therefore

x + y = 11 → x + f(x) = 11     |subtract x from both sides

x - x + f(x) = 11 - x

f(x) = -x + 11

The correct function is f(x) = 11 - x, has the same graph as x + y = 11, which corresponds to option B.

Therefore, the correct answer is:

B. f(x) = -x + 11

Here,

To find the function with the same graph as x + y = 11,

we need to isolate y in the equation to make it of the form y = f(x).

Given equation: x + y = 11

Subtract x from both sides of the equation:

y = 11 - x

Now, we have the equation in the form y = f(x).

so, we get, f(x) = -x + 11

i.e. The function which has the same graph as x + y = 11 is: f(x) = -x + 11

so, we have,

The correct function is f(x) = 11 - x, has the same graph as x + y = 11, which corresponds to option B.

Therefore, the correct answer is:

B. f(x) = -x + 11
