What is the resulting equation when the expression for y in the second equation is substituted into the first equation?

2 answers:

8 0

Take the second equation already set to y and substitute it into the first equation for y...

3x + (6 - 4x) = 1 ... now we simplify
3x + 6 - 4x = 1 .....now combine like terms
-x + 6 = 1 .....

Y=6-4x
sub 6-4x for y

3x+y=1
3x+(6-4x)=1
3x+6-4x=1
3x-4x+6=1
-x+6=1

What are the coordinates of the endpoints of the midsegment for △LMN that is parallel to LN¯¯¯¯¯ ?

ycow [4]

The coordinates of the endpoints of the midsegment for △LMN that is parallel to LN are (3, 4.5) and (3, 3).

Explanation:

Given that △LMN

We need to determine the coordinates of the endpoints of the midsegment for △LMN that is parallel to LN

The midsegment of the triangle parallel to side LN is the midsegment connecting the midpoint of side LM and the midpoint of side MN.

The midpoint of LM is given by

$\left(\frac{0+6}{2}, \frac{5+4}{2}\right)$

Simplifying, we get,

$(\frac{3}{2}, \frac{9}{2} )=(3,4.5)$

The midpoint of MN is given by

$\left(\frac{0+6}{2}, \frac{2+1}{2}\right)=(3,3)$

Thus, the coordinates of the endpoints of the midsegment for △LMN that is parallel to LN are (3, 4.5) and (3, 3).

Use k as the constant of proportionality to write the equation expressing the relationship: y varies inversely as x.

yan [13]

"Inversely" generally means the relationship is proportional to the reciprocal.
y = k/x

Luis earned 3% interest on the $780 he had in his account. How much money did he have in total?

grandymaker [24]

Answer: $803.4

Step-by-step explanation: he earned 3% on interest so that means the equation is 780 + 3% (correct me if i'm wrong) so 780 + 3% is $803.4 which is 803 dollars and 4 cents

There are 60 minutes in an hour. The total number of minutes is a function of the number of hours, as shown in the table. Does t

Alexxx [7]

Answer:

Step-by-step explanation:

It represents a linear function because there is a constant rate of change.

Step-by-step explanation:

Since, if the rate of change for y ( output value ) with respect to x ( input value ) remains constant for a function then it is called linear function.

Here, number of hours represents input value and minutes represents the output value,

Now, By the given table,

The function is passing through the points (1,60), (2,120), (3,180), (4,240) and (5,300),

Also,

⇒ The rate of change output value with respect to input value remains constant,

Hence, It represents a linear function because there is a constant rate of change.
