Answer:

To find the solutions to the system of equations we need to graph the following equations:

y = 8 - 4x (Red line)

y = 2x - 4 (Blue line)

The point of interception, is the solution to the system of equations.

By looking at the graph attached, you can see that the point of itersection is at (2,0)

Lincoln has p pennies and n nickles .he has at least $0 worth of coins altogether.write this situation as a inequality

skelet666 [1.2K]

Answer:

$p+n=0$

Step-by-step explanation:

Given that Lincoln has $p$ pennies and $n$ nickles and that his total worth is $0,

we can express his total using the inequality:

$p+n=0$

Where the sum of n and p is his total

Hence, Lincoln's situation is expressed as p+n=0

Rahul sold a painting at 10% profit. If he had sold it for 240 more, he would have made 15% profit. What is the C.P. of the pain

dangina [55]

Answer:

$4800

Step-by-step explanation:

Let x be the C.P of the painting.

Profit=10% of x

Profit= $\frac{10}{100}\times x=\frac{10x}{100}$

If S.P increase by 240 then

Profit=15% of x= $\frac{15x}{100}$

For first case

S.P=C.P+ Profit

S.P=x+10x/100

S.P= $\frac{100x+10x}{100}=\frac{110}{100}x$

For second case

New S.P $=x+\frac{15}{100}x$

= $\frac{115}{100}x$

According to question

$240+S.P=\frac{115}{100}x$

$240+\frac{110x}{100}=\frac{115}{100}x$

$240=\frac{115}{100}x-\frac{110x}{100}$

$240=\frac{115x-110x}{100}$

$240=\frac{5}{100}x$

$x=\frac{240\times 100}{5}$

$x=4800$

Hence, the C.P of the painting=$4800

Answer:

Step-by-step explanation:

The translation of the question is as shown;

First note that the original number is 35

The sum of 35 and one-fifth part of itself .

= 35 + 1/5(35)

= 35+7

= 42 ... A

sum of one-seventh part of itself and 3 will be;

= 1/7(35) + 3

= 5+3

= 8... B

Adding A and B together wiill give us the final result

A+B = 42+8

A+B = 50

The sum of 35 and one-fifth part of itself added to the sum of one-seventh

part of itself and 3 is therefore equivalent to 50

He graph shows the velocity f(t) of a runner during a certain time interval:

Alex

Option D. The description that best fits the intercept of the graph is The initial velocity of the runner was 6 m/s, and the runner stopped after 8 seconds.

<h3>How to solve for the intercept of the graph</h3>

The graph has lines that would go through these points, (0,6) and pair (6,8). In the other graph, it goes through 6, 8 and 8, 0.

The initial velocity of this runner is seen to be 6m/s. As he runs this would increase and while he slows down it would fall. The stop time of the runner is going to be at 8 minutes.

<h3>Complete question</h3>

Which of the following describes the intercepts on the graph?

The initial acceleration of the runner was 8 m/s2, and the runner stopped after 6 seconds.

The initial acceleration of the runner was 6 m/s2, and the runner stopped after 8 seconds.

The initial velocity of the runner was 8 m/s, and the runner stopped after 6 seconds.

The initial velocity of the runner was 6 m/s, and the runner stopped after 8 seconds.
