Determine whether each ordered pair is a solution of the inequality. x+2y>10
The ordered pair of a solution of the inequality are (10, 0) and (0, 5).
The given inequality is x+2y>10.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Graph the inequality by finding the boundary line, then shading the appropriate area.
The solution of the inequality is (10, 0) and (0, 5).

Thus the largest length is 15 inches
Size (l) is 14 inches.
Size (w) = 4 inches.
Height is 4 inches (h).
The distance between one bottom corner and the opposite top corner is known as d. Find s, the diagonal across the bottom of the box, first.

A Linear equation in point slope form using the first point 3/4h , 9 in that can be used to determine the level of chocolate syrup in dispenser after x hours is y = -4x + 12 .
In the question ,
it is given that
in 3/4 hours the the level of chocolate syrup was 9 inch ,
So , the first point is (3/4,9) .
in 5/4 hours the level of chocolate syrup in the dispenser was 7 inch .
So , the second point is (5/4,7)
to find the linear equation we first need to find the slope .
Slope = (7-9)/(5/4-3/4)
= -2/(2/4)
= -4
So , the equation in slope intercept form having point (3/4 , 9) and slope -4 is .
(y - 9) = -4(x - 3/4)
y - 9 = -4x + 3
y = -4x + 3 + 9
y = -4x + 12
Therefore , The linear equation is y = -4x + 12 .

Given that r is a vector 125 km due north, and s is a vector 164 km due south, what are the
hr
magnitude and direction of the sum r + s?
Answer:
39 km due southStep-by-step explanation:
Since the two vector have opposite directions, their sum will be the difference of magnitudes:
r + s = 164 - 125 = 39And the direction is the same with the vector with greater magnitude, so it is south.
Answer:
Magnitude = 39 km
Direction = South
Step-by-step explanation:
Formula we use,
→ r + s
Now the required answer will be,
→ r + s
→ 164 + (-125)
→ 164 - 125
→ 39 km
Thus, answer is 39 km due south.

Determine the equation of the line that is perpendicular to the given line, through the given point
y = x -1 ; (-6,2)
The equation of the line is y=-x-4
How to find whether line is perpendicular or not?
Perpendicular lines are those that cross at a right angle when two non-vertical lines in the same plane. Vertical and horizontal lines, or the axes of the coordinate plane, are perpendicular to one another. Two parallel lines' slopes have negative reciprocal slopes.
The given line is
y=x-1
the slope of it is 1
As the slopes of perpendicular lines are negative reciprocals
So, the slope of the perpendicular line is -1
As the point is(-6,2)
y=mx+b
y=(-1)x+b
2=-1(-6)+b
2=6+b
b=2-6

Construct a polynomial function with the stated properties. Reduce all fractions to lowest terms.

The polynomial function with third degree, zeros of −3, −1, and 4, and a y-intercept of −13 is y = -13/12 (x³ - 13x + 12)
Polynomial function:
polynomial function means a functions of single independent variables, in which variables can occur more than once, raised to an integer power.
Given,
Third-degree, with zeros of −3, −1, and 4, and a y-intercept of −13.
And we need to construct a polynomial function with the stated properties and reduce all fractions to lowest terms.
We know that the standard form for the third degree polynomial function is written as,
=> y = K (x + zeros1) (x + zeros2) (x + zeros3)
The third degree, zeros of the function is -3, -1 and -4.
Now, we have to apply it on the general form,
=> y = K (x -3) (x - 1) (x + 4) ----------------------(1)
Here we know the value of y intercept is -13 then the value of x is 0.
So, it can be written as,
=> -13 = K(0 - 3) (0 - 1) (0 + 4)
=> -13 = K (12)
Therefore, the value of K = -13/12
Now, apply the values on the equation (1), then we get,
=> y = -13/12 (x -3) (x - 1) (x + 4)
Therefore, the third degree polynomial function is,

Step-by-step explanation:
Johnny has some nickels and dimes in his pocket, and the change is worth $0.75. He has twice as many dimes and nickels. How many of each type of coin does Johnny have? // system of equations questions it requires 2 equations and to define the x and y
=====================================================
Work Shown:
x = number of nickels
y = number of dimes
5x = value of the nickels only (cents)
10y = value of the dimes only (cents)
5x+10y = total value of all the coins = 75 cents
One equation we can form is 5x+10y = 75.
"he has twice as many dimes as nickels" tells us that y = 2x. We can replace every copy of y with 2x and solve for x as shown in the steps below.
5x+10y = 75
5x+10(y) = 75
5x+10(2x) = 75 ... plug in y = 2x
5x+20x = 75
25x = 75
x = 75/25
x = 3
This value leads to y = 2x = 2*3 = 6
Johnny has 3 nickels and 6 dimes.
------------------
Check:
1 nickel = 5 cents
3 nickels = 3*5 = 15 cents
1 dime = 10 cents
6 dimes = 6*10 = 60 cents
3 nickels + 6 dimes = 15 cents + 60 cents = 75 cents = $0.75
