9x + 15 > 3- 3x what’s the solution and steps

Answers

9x +15 > 3-3x
Subtract 3 on both sides of the inequality sign
9x + 12 > -3x
Now subtract -9x on both sides of the inequality sign
12 > -15x
Now divide both sides of the inequality sign by -15
x > -12/15
Reduce it
x > -4/5

A line segment of length k is divided into 3 equal parts what is the distance between midpoints of the first and third segments

Answers

Line segment of length k is divided into 3 equal parts.

so first segment is 0-k/3 and third segment is 2/3k-k

so mid-pt of 1st = k/6 and 3rd = 5/6k

so the distance in between = 5/6k-k/6 = 4/6k = 2/3k

Write the equation of the line that passes through the points (3,-2) and (-2,8).

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

Let's find the slope (m) of line passing through points (3 , -2) and (-2 , 8) :

[tex] \dfrac{y_2 - y_1}{x_2 - x_1} [/tex]

[tex] \dfrac{ - 2 - 8}{3 - ( - 2)} [/tex]

[tex] \dfrac{ - 10}{5} [/tex]

[tex] - 2[/tex]

slope (m) = -2

now, let's plug the value of slope (m) and coordinates of point (3 , -2) to find c (y - intercept)

[tex]y = mx + c[/tex]

[tex] - 2 = (3 \times - 2) + c[/tex]

[tex] - 2 = - 6 + c[/tex]

[tex]c = - 2 + 6[/tex]

[tex]c = 4[/tex]

Y - intercept of the given line is 4, so the required equation will be :

[tex]y = - 2x + 4[/tex]

at what ordered pair do the lines x=4 and y=-3 intersect?

Answers

x = -4 is a vertical line. The x-coordinate will always stay the same regardless of any y-coordinate paired with it.

y = -3 is a horizontal line. Similarly, the y-coordinate will always stay the same regardless of any x-coordinate paired with it.

Therefore, they will intersect at point (4, -3).

Perimeter wall area

21(1.5) = 31.5 ft²

Answer:

x=9

Therefore angles 7x-4 = 6x-4 = 59 degree

Step-by-step explanation:

7x-4 = 6x-4 Findings; alternate angles

Although any coefficient angles can be set = to each other.

7x-6x-4 = +5 Subtract 6x from both sides

x -4 = 5

x = 5+4 Add 4 to each side

x = 9

Find the angle degree

6(x) + 5 = 7(x) - 4 Plug 9 in to x

6(9) + 5 = 7 (9) - 4

54 + 5 = 63-4

59 = 59

x = 59 degree.

Slope= 9, (-5,2)

Answers

If an equation had a slope of 9 and went through the point (-5, 2) then the equation would be:

y = 9x + 47

Explanation: slope intercept equation is represented by y = mx + b. M represents slope and B represents the y-intercept (which is the place where the graph crosses the y-axis.) So using the info we know about the graph going through (-5, 2) and that the slope is 9 (or m = 9) then we could determine that the y-intercept is 47. Now, using everything we have found thus far, we can fill in the slope intercept equation.

The graph is shown below:

7. A caterer knows there is one broken egg in every 3 cartons. A carton contains 12 eggs.
A caterer plans to serve 1200 eggs. What is the best estimate the number of cartons the caterer should buy?

Answers

9514 1404 393

Answer:

103

Step-by-step explanation:

For 1200 eggs, the caterer needs ...

(1200 eggs)/(12 eggs/carton) = 100 cartons

of unbroken eggs.

The rate of broken eggs is 1 in 3×12 = 1 in 36, so the caterer must buy 36 eggs for each 35 unbroken eggs delivered.

Then the number of cartons that must be purchased is ...

(100 cartons)(36/35) = 102 6/7 cartons

The caterer should buy 103 cartons of eggs.

Rodney and Josiah each bought a package of the same kind of cookies at
the store. Rodney ate 1/2 package of cookies on Monday and 1/3 of the same package
on Tuesday. Josiah 5/12 ate of his package on Monday and 1/2 of the package on
Tuesday. Who ate more? How much more?

Answers

9514 1404 393

Answer:

Josiah ate 1/12 package more

Step-by-step explanation:

Each of them ate 1/2 package on one of the days. On the other day, Rodney ate 1/3 = 4/12 of the package, and Josiah ate 5/12 of the package.

Josiah ate 5/12 -4/12 = 1/12 more of the package of cookies.
