Answer: Malik uses an app on his phone to track how far he rides his bike. Yesterday, he biked a new trail in a total of 57.5 minutes, including a 2.5-minute water break. The app notified Malik that he rode 10 miles. What was Malik's average pace while biking?

Answer:

5.5 Minutes per mile

Step-by-step explanation:

Malik biked 10 miles at a pace of p minutes per mile. His water break added 2.5 minutes to his time. It took him a total of 57.5 minutes to complete the trail. This equation represents the situation.

10p      time spent biking

+

2.5 time for water break

=

57.5  total time

Now, solve the equation for p.

10p+2.5

= 57.5

10p

= 55 Subtract 2.5 from both sides

p

= 5.5 Divide both sides by 10

Malik's average pace was 5.5 minutes per mile.

Please tell me if I’m wrong.

Answer:

Step-by-step explanation:

The simplest line you can draw with a slope of 4 is y = 4x. Use The equation to make a table

y = 4x

x    1     3     5

y    4    12    20

So I just multiplied 4 by  3 and 5 red graph below shows the three points on the line. (1,4),(3,12),(5,20)

What about a more complex line.

y = 4x + 5

x 1  3  5

y 9 17 25

The green line show (1,9),(3,17),(5,25)

Step-by-step explanation:

(x - 3)/x = -8/(x + 3) , x ≠ 0 or -3

(x - 3)(x + 3) = -8x

x² - 9 = -8x

x² + 8x - 9 = 0

x² + 9x - x - 9 = 0

x(x + 9) - 1(x + 9) = 0

(x + 9)(x - 1) = 0

x = -9

x = 1

x ≠ 0 or -3

-9 ≠ 0 or 3 PROVED

x ≠ 0 or -3

1 ≠ 0 or -3 PROVED

Answer: M= 2 C= 4 (0,4)

Step-by-step explanation:

Formula- y=mx+c where m is the gradient and c is the y intercept

In y=2x + 4,

2 is in the place of m and 4 is in the place of c. So, m= 2 and c=4. The coordinates of the y intercept would be (0,4)

Answer:

4 1/2 inches

Step-by-step explanation:

Hi! I hope this helps!:

Since Ms. Henderson's plant is 6 1/3, all we need to do is subtract 1 5/6 from it! We do this because it says, "1 5/6 inches taller than Megan's plant".

For the next steps, you can change the mixed numbers into decimals or into improper fractions! 6 1/3 would be 19/3. 1 5/6 would be 11/6. You can find a common denominator for both. I would make 19/3 to 38/6.

Lastly, you need to subtract and make it into simplest form! 38/6 - 11/6 = 27/6.

You could simplify it to 9/3, 4.5, or 4 1/2 inches.

Answer:

  (-3, 9), (-1, 11), (0, 12), (4, 16), (6, 18)

Step-by-step explanation:

The function definition tells you that adding 12 to the x-value will give you the value of f(x).

  -3 +12 = 9, for example

The (x, f(x)) values for the table are shown above.

==========================================================

Explanation:

For the original two digit number, we have:

The original number is 10x+y. For instance, if x = 5 and y = 7, then we have 10x+y = 10*5+7 = 57.

This original number 10x+y swaps its digits to 10y+x. Then we add up the two expressions:

(original)+(swapped) = (10x+y)+(10y+x) = 11x+11y = 11(x+y)

This sum is stated to be 154

11(x+y) = 154

x+y = 154/11

x+y = 14

Then we're told that "the ones digit in it (the original number) is 2 less than the tens digit". Meaning that y = x-2 is another equation we can use. We'll plug this into the previous equation we found and solve for x

x+y = 14

x+x-2 = 14 ... replace y with x-2

2x-2 = 14

2x = 14+2

2x = 16

x = 16/2

x = 8 is the tens digit of the original number

y = x-2

y = 8-2

y = 6 is the units digit of the original number

The original number is 10x+y = 10*8+6 = 86

As a check, adding 86+68 = 154 which confirms our answer.

Answer:

positive

Step-by-step explanation:

the discriminant of the function is postive.

because from the graph we notice that it has 2 intercepts on x-axis, which means the function has 2 real solution when y=0

that implies the discriminant is positive.

[tex]\Delta = \sqrt{b^2-4ac}[/tex]

if [tex]\Delta > 0[/tex] we have 2 distinct real solution

if [tex]\Delta <0[/tex] we have no real solution but 2 complex solutions

if [tex]\Delta = 0[/tex] we have 2 identical real solution

Answer:

4(3x-8)=52

divide both sides by 4

4/4(3x-8)=52/4

3x-8=13

add both sides by 8

3x-8+8=13+8

3x=21

divide both sides by 3

3x/3=21/3

1) A(1;2) and slope=3.

slope-interception form is y=s*x+i, where s - slope, i - interception.

if to substitute the given coordinates and slope into the equation, then 2=3*1+i, ⇒ i=-1. It means, the required equation is:

y=3x-1.

2) A(1;2) and B(3;-2).

the common form is:

[tex]\frac{x-X_B}{X_A-X_B} =\frac{y-Y_B}{Y_A-Y_B}.[/tex]

If to substitute the given coordinates into the common form, then:

[tex]\frac{x-3}{1-3} =\frac{y+2}{2+2} ; \ => \ \frac{x-3}{-2} =\frac{y+2}{4}; \ => \ y=-2x+4.[/tex]
