How many solutions does this system of equations have?

Answers

Answer:

1 solution

Step-by-step explanation:

A system of linear equations has no solution when the graphs are parallel.

asap... plz can you do these for me​

Answers

Given:

The graph of a quadratic function [tex]y=x^2-4x+3[/tex].

To find:

(a) The coordinates of the turning point.

(b) The roots of the equation [tex]y=x^2-4x+3[/tex]

Solution:

(a)

From the given graph it is clear that first the graph is decreasing after that it is increasing. So, the minimum point is the turning point.

The turning is at (2,-1) because the distance between the turning point from the y-axis is 2 and from the x-axis is 1 in the downward direction.

Therefore, the coordinates of the turning point are (2,-1).

(b)

The x-intercepts are the roots of an equation because roots are the x-coordinates of the points where the graph intersect the x-axis.

From the given graph it is clear the graph intersect the x-axis at x=1 and x=3.

Therefore, the roots of the given equation are 1 and 3.

-5x + 11 = -8(4 + 6x) What are the steps?

Answers

Answer:

[tex]x = - 1[/tex]

Step-by-step explanation:

[tex] - 5x + 11 = - 8(6x + 4)[/tex]

[tex] = > - 5x + 11 = - 48x - 32[/tex]

Lets keep the variable terms in L.H.S. and the constant terms in R.H.S.

[tex] = > 48x - 5x = - 32 - 11[/tex]

[tex] = > 43x = - 43[/tex]

Lets divide 43 on both the sides.

[tex] = > \frac{43x}{43} = \frac{ - 43}{43} [/tex]

[tex] = > x = - 1[/tex]

Which line is the graph of y= -2x+2? D B A C

Answers

the answer is b because in y=mx+c, m is the gradient and c is the y-intercept. since the y-intercept is 2, we can safely discard d as an option. when a gradient is -2, it is a negative graph which means a and c is out. so, you’re left with b!
the answer is line b

10. A test car went 64 miles on 2 gallons in the morning, 16 miles on ½ gallon at noon, and 32 miles on 1 gallon at 5 pm. Is the relationship a proportional relationship?

please answer properly and show or tell me all your work

Answers

Answer:

9. 10.8 miles

10. Yes

Step-by-step explanation:

To solve number 9 I multipled 0.24 x 45 to find the distance the biker can bike in 45 minutes.

Number 10 is yes because the numbers continue proportionaly. If you work it out, you can see that each half gallon takes the car 16 miles. The distances went 16 miles for 1/2 gallon, 32 miles for 1 gallon, would go 48 miles for 1 1/2 gallons, and went 64 miles for 2 gallons.

Write a function rule that gives the total cost c(p) of p pounds of sugar if each pound costs $0.42.


A. c(p) = p + 0.42

B. c(p) = 42p

C. c(p) = p/0.42

D. c(p) = 0.42p

Answers

Answer:

D. c(p) = 0.42p

Step-by-step explanation:

total cost = .42(P)

Example: 5 lbs

$2.10 = $.42(5)

c(p) = 0.42p <== ur function

Since a pound of sugar increases proportionally to the total cost of sugar bought, then the function can be written as:

c(p) = 0.42p

Where: c(p) = total cost of sugar bought

p = pounds of sugar

c(p) is a function of p, because c(p) depends on p.

Answer: The function rule that gives the total cost is given by

Step-by-step explanation:

Let the number of pounds of sugar be 'p'.

Let the total cost would be C(p).

Cost of each pound = $0.42

So, the function rule would be

Hence, the function rule that gives the total cost is given by

Sports of the 25 baseball players on the baltimore orioles 2005 roster, 17 threw right handed, 12 were over 30 years old, and 9 both threw right handed and were over 30 years old. How many players on the team neither threw right handed nor were over 30 years old?

Answers

Answer: 5

Step-by-step explanation:

Let R be the event that players threw right-handed.

Let O be the event that players were over 30 years old.

Given: Total players = 25

n(R) = 17 ,   n(O) = 12  , n(R and O)=9

According to the probability formula,

n(R or O) = n(R)+n(O)-n(R and O)

⇒ n(R or O) =17+12-9

⇒ n(R or O) = 20

Now , n(neither R nor O) = Total - n(R or O)

= 25-20

=5

Hence, the number of players on the team neither threw right-handed nor were over 30 years old = 5

Mike took a taxi from his home to the airport. The taxi driver charged an initial fee of 6plus3 per mile. The total fare was $24, not including the tip. How many miles did Mike travel by taxi on this ride?


A 2


B 6


C 8


D 10

Answers

Answer:

6 miles.

Step-by-step explanation:

To solve this problem, lets make an equation in slope-intercept form (y = mx + b)

The initial fee is $6. This is our y-intercept (b) as it is unchanging.

Our slope (m) would be $3, as it changes value per mile, which will be represented by x.

$24 was the total fare, so this is our y.

We have:

24 = 3x + 6

Subtract 6 from both sides.

24 - 6 = 3x + 6 - 6

We get:

18 = 3x

Divide by 3 on both sides.

18/3 = 3x/3

We get:

6 = x

So, Mike traveled 6 miles.

Circle O has a radius of 5 centimeters and central angle AOB with a measure of 60°. Describe in complete sentences how to find the length, in terms of a radian measure, of AB.

Answers

Answer:

We can use the formula for finding arc length given ccx central angle and radius.(insert formula below) We then substitute 5 in for r and and 60 for x. We multiply 2 pi times 5 which gives us 10. We then reduce the fraction of 60/360 to 1/6. We multiply 10 pi by 1/6 and that gives us

10 pi/6 or 5 pi/3

Step-by-step explanation:

We can use the formula

[tex]2\pi \times r( \frac{x}{360} )[/tex]

to find the arc length where r is the radius.

and x is the arc measure.

Plug it in for the numbers

[tex]2\pi \times 5( \frac{60}{360} )[/tex]

Multiply 2 pi times 5=10 pi

[tex]10\pi( \frac{60}{360} )[/tex]

Simplify 60/360 to 1/6

[tex]10\pi \times \frac{1}{6} = \frac{10\pi}{6} [/tex]

Reduce it to

[tex] \frac{5\pi}{3} [/tex]
