Answers

Answer 1

Answer:

y=3/4x+10

Step-by-step explanation:

lts take two points

(-4,7)

(0,10)

so slope is 3/4

so 3/4*-4+b= 7

-3+b=7

b=10

y= 3/4x+10

if my answer helps please mark as brainliest.

Answer 2

Answer:

y = 3/4 x + 10

Step-by-step explanation:

the b is 10 because y is 10 when x is 0

to find the x, plug in any variable from the chart into the equation y=mx+b

i used (-4, 7), so the equation would be 7=m(-4)+10

solve for x

-4m=7-10=-3

m=3/4

Each bag of dog food cost $7.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

Molly bought 10 bags of the same dog food.

She had a coupon for $5.

and, the amount without coupon is $65.

Then, the total amount is

= 65 + 5

= $70

So, the price per bag is

= 70/ 10

= $7

how do i find a slope

Answers

Answer:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points

Answer:

To the find slope in slope-intercept form (y=mx+b) you just find the m of the equation for example: y=4x+8 the 4 is the slope since it is replacing the m

To find the slope in two points (x1,y1) (x2,y2) follow this formula

y2-y1/x2-x1

For example: Find the slope of (4,9) and (9,19)

19-9/9-4 Which is 10/5 simplify: 2

Jasmine gets paid $150 each week and $55 for every laptop that she sells. Write and equation that represents her weekly income.

Answers

Answer:

If x represents the number of laptops sold and y represents the total weekly income, our equation would be y = 55x + 150

Answer:

Step-by-step explanation:

Every week, the given or set in stone amount of money she receives $150. So automatically, the first part of the equation is 150x, because x represents the number of weeks, and 150 is $150. So for instance, if she works for two weeks, she will earn $300. Anyway, she has an additional amount of money she gets, which is $55 for every laptop she sells. This isn't a set in stone amount of money. She might not always earn the extra $55, because she might not sell a laptop for a certain week. So, the final equation would be 150x+55. Hope this helped :)

Properties for the roots of a quadratic equation,

1). Quadratic equation will have two real roots, discriminant will be greater than zero. [(b² - 4ac) > 0]

2). If the equation has exactly one root, discriminant will be zero [(b² - 4ac) = 0]

3). If equation has imaginary roots, discriminant will be less than zero [(b² - 4ac) < 0].

Discriminant of the given equation = [tex](p+1)^2-4(1)(2p-5)[/tex]

For real roots,

[tex](p+1)^2-4(1)(2p-5)>0[/tex]

HELP??? What is the equation of the line in y=mx+b format?

Answers

Answer:

y = 1/2x - 1

Step-by-step explanation:

To find the slope, you need to find the y-intercept first (or the place the line crosses over the y-line). After you've found the y-intercept (-1), you need to find the next point that the line crosses. This line has a positive slope, so you'll want to look for the next point towards the right. The next point was 1 up and 2 over.

Answer:

y = 2/5x - 1

Step-by-step explanation:

There are a couple of different ways to figure this out, but since you have a graph, the fastest way is to count the slope, or m in the formula, by counting the rise (units up) over run (units to the right), which is 2/5. Then, find the value of b by finding the y-intercept on the graph, or -1.

You pick a card at random. 4 5 6 7 What is P(less than 7)? Write your answer as a fraction or whole number.

Answers

Answer:

3/4 is less than 7.

Step-by-step explanation:

There are 4 numbers but there are only 3 less than 7.

The probability P(less than 7) is 3/4.

What is probability?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

For the given situation,

The cards are numbered as s = {4,5,6,7}

⇒[tex]n(s)=4[/tex]

The event is probability of picking the cards less than 7

Cards less than [tex]7[/tex] , [tex]e=4,5,6[/tex]

⇒[tex]n(e)=3[/tex]

Probability of picking the card is given by [tex]p(e)=\frac{n(e)}{n(s)}[/tex]

On substituting the values,

⇒[tex]p(less than 7)=\frac{3}{4}[/tex]

Thus the probability P(less than 7) is 3/4.
