Using the graphing function on your calculator, find the solution to the system

Mathematics
1 answer:
LekaFEV [45]3 years ago
7 0

Answer:

The expression that comes after solving the two linear equation is independent of variables So , The system of equations has <u>no solutions </u>

Step-by-step explanation:

Given two linear equations as :

2 y - 4 x = 6               .......1

y - 2 x = 7      

Or, y = 2 x + 7            .......2

Now, Solving these two equations

Put the value of y from eq 2 into eq1

So, 2 y - 4 x = 6

∴ 2 × (2 x + 7) - 4 x = 6

Or, 4 x + 14 - 4 x = 6

or, (4 x - 4 x) = 6 - 14

i.e 0 = - 8

∵ The expression that comes after solving the two linear equation is independent of variables So , The system of equations has no solutions Answer

Mrs Jenkins picked some tomatoes from her garden. She used 5/9 of the tomatoes to make pasta sauce. Then she used 3/4 of the rem
dedylja [7]

Answer:

Final answer is 1/3.

Step-by-step explanation:

Question says that Mrs Jenkins picked some tomatoes from her garden. She used 5/9 of the tomatoes to make pasta sauce. After that  she used 3/4 of the remainder to make a salad. Now we need to find about what fraction of the tomatoes did Mrs Jenkins use to make the salad.

As she used 5/9 of the tomatoes to make pasta sauce.

Now remaining amount of tomatoes = 1- 5/9 = 9/9 -5/9 = 4/9

Then she used 3/4 of the remainder to make a salad. So fraction of the tomatoes did Mrs Jenkins use to make the salad = (4/9)(3/4)=12/36=1/3

Hence final answer is 1/3.

for what value of k, the line joining 3x-ky+7=0 is perpendicular to the line joining (4 ,3) and ( 5, -3).
Schach [20]

Answer:

  • k = 18

=========

<h2>Given</h2>

<h3>Line 1</h3>
  • 3x - ky + 7 = 0

<h3>Line 2</h3>
  • Passing through the points (4, 3) and (5, - 3)

<h2>To find</h2>

  • The value of k, if the lines are perpendicular

<h2>Solution</h2>

We know the perpendicular lines have opposite reciprocal slopes, that is the product of their slopes is - 1.

Find the slope of line 1 by converting the equation into slope-intercept from standard form:

<u><em>Info:</em></u>

  • <em>standard form is ⇒ ax + by + c = 0, </em>
  • <em>slope - intercept form is ⇒ y = mx + b, where m is the slope</em>

  • 3x - ky + 7 = 0
  • ky = 3x + 7
  • y = (3/k)x + 7/k

Its slope is 3/k.

Find the slope of line 2, using the slope formula:

  • m = (y₂ - y₁)/(x₂ - x₁) = (-3 - 3)/(5 - 4) = - 6/1 = - 6

We have both the slopes now. Find their product:

  • (3/k)*(- 6) = - 1
  • - 18/k = - 1
  • k = 18

So when k is 18, the lines are perpendicular.

Help I need to know What is the volume of this cylinder?
Likurg_2 [28]

Answer:

V =4923.52 mm^3

Step-by-step explanation:

The volume of a cylinder is

V = pi r^2h

We need to get the radius

r = d/2 = 28/2 = 14

V = 3.14 * 14^2 *8

V =4923.52 mm^3
