Answer:

not proportional

Step-by-step explanation:

If the y-intercept is not zero, the graph does NOT show a proportional relationship. A y-intercept of 4 means the relation is not proportional.

If a system of two inequalities has a solution, then their two half planes intersect , true or false ?

Nana76 [90]

Answer: The answer is true.

Step-by-step explanation: The given statement is

'If a system of two inequalities has a solution, then their two half planes intersect'.

We are to check whether the statement is true or false.

Let a system of two inequalities be

$x+y\geq 3,\\\\2x+5y\leq 10.$

These inequalities has a solution, for example, x = 2, y = 1.

Plotting these inequalities on a graph paper (please see the attached graph), we see that the two half planes intersect, which is represented by the double shaded region in the graph.

Thus, the given statement is TRUE.

Write an algebraic expression for the distance traveled in t hours by a car traveling at 75 miles per hour

marshall27 [118]

That would be 75t

If t = 1
75(1) = 75 miles traveled in 1 hour which is correct if it is moving at 75 miles per hour

1. A positive real number is 2 less than another. When 4 times the larger is added to the square of the smaller, the result is 4

Leona [35]

Answer:

−

√

Step-by-step explanation:

Positive real number =

Other number =

First statement: A positive real number is 2 less than another.

Therefore

Second statement: When 4 times the larger is added to the square of the smaller, the result is 49.

Since the larger number is

, we know that "4 times the

larger" means

The square of the smaller would mean

If you put them together, it would look like

Now create a system of equations like the following:

From the first equation, we can understand the value of

in terms of

, which is

Replace the

in the second equation with

(

Now that we have an equation with only one variable, solve for

Below is a potential way one can solve this equation:

1. Expand the bracket.

2. Form a quadratic equation (
