Question 1. It is graph 3 since the y-intercept in the equation is -2 and the y-intercept on the graph 3 is -2. It is also a quadratic function.

Question 2. It is graph two because the equation listed represents a quadratic function that is positive (graph opens up).

Question 3. It is graph 4 since the y-intercept is 2 and the only graph with that intercept is graph 4. Also, the equation represents a linear function.

Hope this helped :))

Write an equation of the line that passes through (1,2) and is parallel to the line y=-5x+4

valentinak56 [21]

Answer:

The equation of the Parallel line to the given line is 5x+y-7=0

Step-by-step explanation:

Explanation:-

Given that the line y = - 5x+4 and point (1,2)

The equation of the Parallel line to the given line is ax+by+k=0

Given straight line 5x + y -4 =0

The equation of the Parallel line to the given line is 5x+y+k=0

This line passes through the point (1,2)

5x+y+k=0

5(1)+2+k=0

⇒ 7+k=0

k =-7

Final answer:-

The equation of the Parallel line to the given line is 5x+y-7=0

A fruit stand has to decide what to charge for their produce. They need \$10$10 for 44 apples and 44 oranges. They also need \$1

KatRina [158]

Answer:

We can't find a unique price for an apple and an orange.

Step-by-step explanation:

Suppose, the price of an apple is $x$ and the price of an orange is $y$

They need $10 for 4 apples and 4 oranges. So, the first equation will be.......

$4x+4y=10 ........................................(1)$

They also need $15 for 6 apples and 6 oranges. So, the second equation will be........

$6x+6y= 15 ........................................(2)$

Dividing equation (1) by 2 on both sides : $2x+2y= 5$

Dividing equation (2) by 3 on both sides : $2x+2y=5$

So, we can see that both equation (1) and (2) are actually same. That means, we will not get any unique solution for $x$ and $y$ here. Both $x$ and $y$ have "infinitely many solutions".

Thus, we can't find a unique price for an apple and an orange.
