the distance between two towns is 300 km two cars start simultaneously from this towns and move towards each other the speed of one car is more than the other by 7 km per hour if the distance between the cars after 2 hours is 34 kilometre find the speed of the cars​

Answers

Answer 1

Answer: I think its 131.19, but not too sure.

Step-by-step explanation:

To find the speed, you would do distance/time, so I added 300 and 7. I got 307, then I divided 307 (distance) from 2.34 (time). I got 131.19

Do you want the speed of both cars? then the answer would be:

(300)- first car= 128.20

(307)- second car= 131.19 (if you need to round this answer, it would be 131.2)

Write a recursive formula for the arithmetic sequence:

7,4,1,-2

Answers

a1 = 7
a(sub)n = a(sub)n-1 - 3

(sub) indicates the values touching the parenthesis are written as a subscript.

The above would be the recursive formula as you are taking the previous number and subtracting 3 to get the next number in the sequence.

Answer:

N - 3

Step-by-step explanation:

It is a series of -3 so:

7 -3 = 4

4 - 3 = 1

1 - 3 = -2

So:

N-3

where N is the present value in the sequence.

Find the equation of the linear function represented by the table below in slope-intercept form.

Answers

Answer:

y= 8x +7

Step-by-step explanation:

slope-intercept form:

y= mx +c, where m is the gradient (or slope) and c is the y-intercept.

Since it is a linear function, the gradient of any 2 points would be equal.

[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]

Thus, gradient of the line

[tex] = \frac{39 - 23}{4 - 2} \\ = \frac{16}{2} \\ = 8[/tex]

Subst. m=8 into the equation:

y= 8x +c

To find the value of c, substitute a pair of coordinates.

When x=0, y= 7,

7= 8(0) +c

c= 7

Thus, the equation of the linear function is y= 8x +7.

Solve 3q - 5 = 13 for q.

Answers

Answer:

[tex]q = 6[/tex]

⇒ Step-by-step explanation:

Lets solve!

[tex]3q -5 = 13[/tex]

⇒ First we add 5 to both sides.

[tex]3q -5 = 13[/tex]

   [tex]+ 5[/tex]     [tex]+ 5[/tex]

    [tex]3q = 18[/tex]

⇒ Next we divide both sides by 3.

 [tex]\frac{3q}{3} = \frac{18}{3}[/tex]

[tex]q = 6[/tex]

⇒Woohoo! Brainliest Appreciated! Hope I helped!

Answer:

q = 6

Step-by-step explanation:

To solve for q, isolate the variable.

3q - 5 = 13

Move -5 to the right side and perform the inverse operation. Since you were subtracting on the left, add on the right.

3q = 13 + 5

3q = 18

The last step is to isolate the variable by dividing 3 by 18. The reason you divide on the right is because you were multiplying on the left, and you need to perform the inverse operation.

q = [tex]\frac{18}{3}[/tex]

q = 6

Mary sees 40 elephants and 15 baby elephants at the zoo. What is the ratio of elephants to baby elephants?

Answers

Answer:

8:3

Step-by-step explanation:

You divide them both by 5.

Answer:

40:15 = 8:3

Step-by-step explanation:

This is the answer because:

1) Since there are 40 elephants and 15 baby elephants, the answer would be 40:15, but we want to simplify the ratio. In order to simplify the ratio, just divide each number by 5:

40 ÷ 5 = 8

15 ÷ 5 = 3

8:3

Therefore, the answer is 8:3.

I am having a hard time with simultaneous equations specifically the elimination method, i want to know when do we subtract and when do we add, so if u know how its done plz help im confused

Example :
3x-2y =7
4x+y = 13

Plz solve it too-

Answers

Answer:

The solution to these two equations is (3, 1)

Step-by-step explanation:

So for the elimination method, we are basically multiply each equation by a factor that would allow us to cancel them out..

We could rewrite the equations as the following to make the elimination method easier:

-2y + 3x = 7

y + 4x = 13

We could multiply the second equation by positive 2 in order to cancel out the y from the first equation when we add.

-2y + 3x = 7

2y + 8x = 26        --->  Now we have 11x = 33, when we simplify, we have x = 3.

Now to find our y value in order to find the solution, we would just plug in our x value and solve for y. **We can use either equation to find the answer for this...

-2y + 3x =7.

-2y + 3(3) = 7

-2y + 9 = 7

-2y = -2

y = 1.

We can double check our answer by plugging in both x and y values into the second equation.

4(3) + 1 = 13.

12 + 1 = 13, so we are correct.

The solution to these two equations is (3, 1)

How do I solve this equation and find the solutions?

x = 10

Step-by-step explanation:

x-sqrt(2x+5) = 5

2x+5 = 25-10x+x^2

x = 10

Hope this helped!

Answer:

x = 5

Step-by-step explanation:

x - 5 = [tex]\sqrt{2x+5}[/tex] ( x > 5)

(x - 5)² = ( [tex]\sqrt{2x+5}[/tex] )²

x² - 10x + 25 = 2x + 5

x² - 12x + 20 = 0

(x - 10)(x - 2) = 0

[tex]x_{1}[/tex] = 10

[tex]x_{2}[/tex] = 2 strange root, does not satisfy the condition x > 5 ( 2 - [tex]\sqrt{2*2+5}[/tex] ≠ 5 )

10 - [tex]\sqrt{2*10+5}[/tex] = 5

10 - 5 = 5

5 = 5

What is a polynomial expression?

Polynomial is made up of two terms, namely Poly (meaning “many”) and Nominal (meaning “terms.”). A polynomial is an expression composed of variables, constants, and exponents, combined using mathematical operations such as addition, subtraction, multiplication, and division (No division operation by a variable). Based on the number of terms present in the expression, it is classified as monomial, binomial, and trinomial. For example P(x) = x2-5x+11

Given here, the expression as (256x²⁵⁶)^³/₈

=(256)^³/₈ × (x²⁵⁶)^³/₈

=(2⁸)^³/₈ × (x³²)^³

=2³ × x⁹⁶

Hence, the answer is 8x⁹⁶
