NeTakaya

Answer:

the cost of each cookie is $\$1.25$

the cost of each muffin is $\$1.00$

Step-by-step explanation:

Let

x-----> the cost of each cookie

y----> the cost of each muffin

we know that

$8x+3y=13$ -----> equation A

$4x+6y=11$ -----> equation B

Using a graphing tool

The solution of the system of equations is the intersection point both graphs

The intersection point is $(1.25,1)$

see the attached figure

therefore

the cost of each cookie is $\$1.25$

the cost of each muffin is $\$1.00$

For f(x) =4x+1 and g(x) = x^2 - 5 find (f•g)(x)

Vsevolod [243]

Answer:

The value of function (fog)(x) is 4 x² - 19

Step-by-step explanation:

Given function as :

f(x) = 4 x + 1

g(x) = x² - 5

So , function (fg(x)) can be written as

(fog)(x) = 4 ( x² - 5 ) + 1

Or, (fog)(x) = 4 x² - 20 + 1

Or, (fog)(x) = 4 x² - 19

Hence The value of function (fog)(x) is 4 x² - 19 Answer

Answer: 4x + x = 35 or 5x = 35

Step-by-step explanation:

Let the short side of triangle is x unit,

Thus, According to the question,

The other longer sides are 2x and 2x,

Thus, the perimeter of the isosceles triangle = 2(2x) + x = 4x + x

But, the perimeter of the triangle = 35 inches,

⇒ 4x + x = 35

⇒ 5x = 35

⇒ x = 7

Therefore, the measurement longer sides of the triangle = 2x = 2×7 = 14 inches

And the measurement of the shorter side = x = 7 inches
