For this case we have the following system of equations:

$y = x\\y = -x + 4$

We want to find the graphical solution of the system of equations. To do this, we graph both lines (See attached image).

The solution of the system is the point of interception of both functions. In this case, the solution is given by:

$(x, y) = (2,2)$

Answer:

$(x, y) = (2,2)$

See attached image

Answer:the y=x graph will have a slope of positive one and the y intercept would be 0. The y=-x+4 graph will have a slope of negative one ( line going down) and have a y intercept of 4

A road has a 16.7% grade.<br>Why might we want to warn drivers of a grade like this?

never [62]

The higher the percentage, the steeper the grade and the steeper the hill. This warning is issued so drivers are more careful (otherwise they would probably get into more accidents).

Find two positive numbers whose product is 64 and whose sum is a minimum. (If both values are the same number, enter it into bot

DedPeter [7]

Answer:

X = 8, y = 8

Step-by-step explanation:

This question is an optimization problem. Two equations are going to be needed here

n = x+y

P = xy

Such that 64 = xy

When we divide through by x we get:

y = 64/x

So that n becomes:

n = x + 64/x

n = x+64x^-1

We take derivative

n' = 1-64x^-2

When n' = 0 then a min|max occurs

0 = 1-64x^-2

Such that:

64/x² = 1

Divide through by x²

64 = x²

x = √64

x = 8

Remember y = 64/x

So,

Y = 64/8

Y = 8.

X = 8, y = 8

Thank you!

74% of the animals at an animal shelter are dogs. About what fraction of the animals at the shelter are dogs? and also what is t

lozanna [386]

Answer:

Thus, 37/50 is the equivalent fraction to 74/100.

Therefore, 37/50 of the animals in the shelter are dogs.

Step-by-step explanation:

Given

Given that 74% of the animals at an animal shelter are dogs.

To determine:

About what fraction of the animals at the shelter are dogs?

Using the equation to find a fraction equivalent to 74%

$\:74\%=\:\frac{74}{100}$

Divide numerator and denominator by 2

$=\frac{\frac{74}{2}}{\frac{100}{2}}\:\:$

Cancel the common factor 2.

$=\frac{37}{50}$

Thus, 37/50 is the equivalent fraction to 74/100.

Therefore, 37/50 of the animals in the shelter are dogs.
