10x = 10

x = 1

5x + 11 > 2x + 38

3x + 11 > 38

Julio and his friend luca were studying at their public library. After they were done studying, they left the library walking in oppopsite directions. Julio walks at a constand speed of 350 feet per minute and luca rides his skateboard at a constand speed of 450 per minute. How far apart are julio and luca after 4 minutes

Answers

Answer:

400 feets

Step-by-step explanation:

Given the following :

Julio's speed = 350 ft/min

Luca's speed = 450ft / min

They both moved in opposite direction

Distance apart after 4 minutes :

Distance = speed * time

Julio's distance after 4 minutes :

350 ft/min × 4 minutes = 1400 feets

Luca's distance after 4 minutes :

450 ft/min × 4 minutes = 1800 feets

Distance apart in feets after 4 minutes :

(1800 - 1400) feets

= 400 feets

The value of y varies directly with x. When y=4, x=12. What is the value of y when x is 42

Answers

Answer:

y would be 14

Step-by-step explanation:

If y=4 and x=12, that means x is 3 times the amount of y. Therefore, if x is 42, y should be three times less the amount. 42/3 is 14 and that's your correct answer!

Write an equation perpendicular to y = -2x - 7 that passes through the point (4,3)

Answers

2x 7-3 equals 7 pies from amny she loves pies

The equation of line perpendicular to the line y = -2x-7 passing through (4,3) is : 2y = x+2

What is slope of line ?

Slope of line is the angle made by the line from positive x-axis in anticlockwise direction, it also denoted the steepness of the line.

Here, the equation of line given is y = -2x-7 first calculating its slope ([tex]m_{1}[/tex]) by comparing it with slope- intercept form of line i.e. y = mx+c

Therefore, the slope of the given line [tex]m_{1}[/tex] is -2.

Now the slope ([tex]m_{2}[/tex]) of the line perpendicular to the given line is calculated using relation :

[tex]\begin{aligned}m_{1}m_{2}&=-1\\m_{2}&=\frac{-1}{-2}\\&=\frac{1}{2}\end{aligned}[/tex]

Now the equation of the line passing through (4,3) and slope 1/2 will satisfy the equation y = mx +c

[tex]\begin{aligned}y&= mx +c \\3&=\frac{1}{2}\cdot 4+c\\c&=1\end{aligned}[/tex]

Therefore the equation of line perpendicular to the line y = -2x-7 passing through (4,3) is : 2y = x+2

[tex]\begin{aligned}y&= mx +c \\y&=\frac{1}{2}x+1\\2y&=x+2\end{aligned}[/tex]

Kelvin Doe has all of these components in his life. From a small village in the Republic of Sierra Leone in West Africa, this teen changed the lives of the people in his community by his innovative approach to life.Kelvin Gets His StartMost teens could not imagine going to bed at 7 p.m. every night, but Kelvin would. Then, in the middle of the night, he would wake up to transform his living room. It was a small electronics scrapyard, as Kelvin explained. Kelvin was always very interested in technology and inventions, but he lived very poorly. His community did not have modern technology. This did not stop Kelvin. He scrounged through scrapyards and dumps looking for basic components to make his inventions work.The Beginning of ChangeThere was always an important piece missing for his inventions. He needed batteries to power his homemade devices. Kelvin did not have the benefit of a science education at school. Yet, he figured out how to make a battery using soda, metal, and tape. These are ingredients he found at a neighborhood dump! With this battery, the possibilities for his inventions were endless.Community ChangesOnce he had perfected the battery, he began to think of ways to improve the lives of the people in his community. One day a week, the government electricity would turn on in the village. The villagers had electricity to power up devices and use their simple light bulb only four times a month. The rest of the month, they were in the dark. Kelvin decided to make a bigger battery. He made a generator to power the homes in the village. Now, they only have to turn on the generators to enjoy the benefits of electric power.DJ FocusAlong with inventing, Kelvin Doe likes to listen to the latest music. His village, though, did not get dependable radio transmission. So, Kelvin melded his love of music and his interest in engineering. He built his own radio station. His teen friends work as reporters and station managers. He now goes by the moniker DJ Focus. I picked this name because if you focus, you can invent anything, explains Kelvin.His Future Looks Bright During a game, the pittsburgh steelers converted 6 of 10 fourths downs into first downs.
