URGENT WILL MARK BRAINLIEST Show your work and solve for x and y. 3x + y = 8 2x + 4y = 12

mars1129 [50]

3x+y=8--(1)

2x+4y=12

x+2y=6--(2)

(1)×1 and (2)×3

$\\ \rm\Rrightarrow 3x+y=8$

$\\ \rm\Rrightarrow 3x+6y=18$

Subtract both

$\\ \rm\Rrightarrow -5y=-10$

$\\ \rm\Rrightarrow y=\dfrac{-10}{-5}$

$\\ \rm\Rrightarrow y=2$

Put the value in eq(2)

$\\ \rm\Rrightarrow x+2(2)=6$

$\\ \rm\Rrightarrow x+4=6$

$\\ \rm\Rrightarrow x=6-4=2$

A function is defined by f(x) = 3x+ 1 What is f(10)?

swat32

Answer:

c) 31

Step-by-step explanation:

Given: f(x) = 3x + 1

We are being asked to find the function's value for x = 10.

Substitute 10 as the value of x in the function:

⇒ f(x) = 3x + 1

⇒ f(10) = 3(10) + 1

⇒ f(10) = 30 + 1

⇒ f(10) = 31

Therefore, the function's value at x = 10 is 31.

Answer:

Thus, a golden retriever should be given 19 teaspoon of medicine.

Step-by-step explanation:

Given that a golden retriever weighing 85 pounds has diarrhea. His medicine is prescribed as 1 teaspoon per 5 pounds.
To find how much medicine should he be given.
Assign a variable. Write a sentence that gives the information to find it.
Translate into a proportion be careful of the units.
Multiply both sides by the Least Common Denominator and simplify. Check the answer.

Step 1 of 3

Write the data in mathematical form and simplify.

Let x=the number of teaspoon

If 1 teaspoon medicine is 5 pounds then 85 pounds is how many teaspoon of medicine.

Translate the statement into proportion.

$\begin{aligned}\frac{\text { pounds }}{\text { teaspoon }} &=\frac{\text { pounds }}{\text { teaspoon }} \\\frac{5}{1} &=\frac{85}{x}\end{aligned}$

Step 2 of 3

Multiply both sides by x and simplify

$$x(5)=\frac{85}{\bcancel{x}}(\bcancel{x})$

5x=85

Divide by 5,

$x=\frac{85}{5}$

Simplify, x=19

Step 3 of 3

Check the answer.

Substitute x=19 in original proportion and simplify.

$$$\begin{aligned}\frac{5}{1} &=\frac{85}{x} \\5 &=\frac{85}{19}\end{aligned}$\\ \\ Hence, $5=5$, True$
