Hello!

<u>What is an x-intercept</u>:

⇒ <em>value of x</em> when the <em>value of y</em> equals '0'

$8x + 5y=25\\8x+5(0)=25\\8x=25\\\\x=\dfrac{25}{8}$

x-intercept is <u>25/8</u>

<u></u>

<u></u>

<u>What is a y-intercept:</u>

⇒ <em>value of y</em> when the <em>value of x</em> equals '0'

$8x+5y=25\\8(0)+5y=25\\5y=25\\y=5$

y-intercept is <u>5</u>

<u></u>

Hope that helps!

The sum of two numbers is 56. The first number is 2 times greater than the second number. What is the second number?

weeeeeb [17]

Answer:

y = 56/3

Step-by-step explanation:

We need to write equations to solve

Let the two numbers be x and y

The sum is 56

x+y = 56

The first number is 2 times greater than the second number.

x = 2*y

Substitute this into the first equation

x+y = 56

2y+y=56

3y = 56

y = 56/3

Edward was running errands on his bike first to be like from his house to the post office to pick up a package the post office i

Karo-lina-s [1.5K]

Answer:

Edward drove altogether of 16.1 miles.

Step-by-step explanation:

Given:

Edward was Running around on his bike.

Distance from home to post office = $4 \frac{4}{5} \ miles$

$4 \frac{4}{5} \ miles$ can be Rewritten as $4.8 \ miles$

Distance from home to post office = $4.8 \ miles$

Now Given:

Distance from Post office to market = 3.25 miles.

Now we will calculate Distance from Home to market.

Distance from Home to market can be calculated by adding Distance from home to post office and Distance from Post office to market.

Framing in equation form we get;

Distance from Home to market = $4.8+3.25 = 8.05\ miles$

Also Given:

his mother picked him up at the market and drove him home.

We need to find the total miles Edward drive altogether.

total miles Edward drive altogether will be equal to Sum of Distance from Home to market and Distance from market to home.

framing in equation form we get;

Total Distance Edward drove = $8.05+8.05 = 16.1\ miles$

Hence Edward drove altogether of 16.1 miles.

Help plz what is 7-6v=-5-8v

kirill115 [55]

<u><em>v=-6 is the right answer. </em></u> First you had to subtract by 7 from both sides of equation, and it gave us, $7-6v-7=-5-8v-7$ . And then simplify, and it gave us, $-6v=-8v-12$ . You can also add by 8v from both sides of equation, and it gave us, $-6v+8v=-8v-12+8v$ . Next simplify, and it gave us, $2v=-12$ . Then you divide by 2 from both sides of equation, and it gave us, $\frac{2v}{2}=\frac{-12}{2}$ . And finally simplify, and it gave us the answer is <u><em>v=-6 is the right answer.</em></u> Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
