The equation of the line in slope intercept form is y = 4x + 5.
How to represent equation of a line?The equation of line can be represented in slope intercept form as follows:
y = mx + b
where
m = slope of the lineb = y-interceptA line passes through the points (0, 5) and (1,9). The slope of the line can be found as follows;
m = slope = 9 - 5 / 1 - 0
m = 4 / 1
m = 4
Hence, let' find the y-intercept of the equation using (0, 5).
y = 4x + b
5 = 4(0) + b
b = 5
Therefore, the equation of the line is y = 4x + 5.

What is the solution to the linear equation 2. 8 y 6 0. 2 y 5y 14 y 10 y 1 y 1 y 10?.
The equation you provided is a linear equation that can be solved by isolating the variable y on one side of the equation. To find the solution for y, we need to follow these steps
First, we will simplify the equation by combining like terms: 2.8y + 0.2y = 5y – 14 + 6 3y = 5y – 8
Next, we need to get y alone on one side of the equation by subtracting 3y from both sides: 0 = 2y - 8
We will add 8 to both sides of the equation: 8 = 2y
Finally, we will divide both sides of the equation by 2 to find the solution for y: y = 4
So the solution for the linear equation 2.8y + 6 + 0.2y = 5y – 14 is y=4.
It's worth mentioning that this is the only solution that this equation has since it's a linear equation which has only one answer.

Part B: if D(t)=1200, find the value of t and interpret its meaning in the context of the problem.
The Chang family has been traveling for 18 hours, thus, t-value is 18.
How should t-test results be interpreted?A significant t-score, also known as a t-value, implies that the groups are distinct, whereas a small t-score suggests that the groups are similar. Degrees of freedom are the values in a study that are open to change and are crucial for determining the significance and reliability of the null hypothesis.
D(t) = 2,280 - 60t
D(t) = 1,200; find t.
D(t) = 2,280 - 60t
1200 = 2280 - 60t
From both sides of the equation, deduct 2280.
1200 - 2,280 = 2280 - 60t - 2,280
- 1080 = - 60t
multiplied by -60 on both sides
- 1080 / -60 = - 60t / -60

A cylinder has a height of 14 millimeters and a radius of 19 millimeters. What is its volume? Use 3.14 and round your answer to the nearest hundredth.
The volume of cylinder = 15,869.56 mm.
Why is the volume of a cylinder formula?The formula for determining a cylinder's volume is the base area times the height. Volume of a cylinder is r2h cubic units.
To calculate a box's volume, you need to know its height, width, and depth. The volume can be calculated by multiplying these three dimensions.
Assume for the moment that the spherical discs are stacked h levels high. The volume of the cylinder will now be calculated by multiplying the discs' base areas by their heights, "h". Therefore, r2h is used to represent the volume of a cylinder with base radius r and height h. The amount of material required to fill an object can be calculated using the volume of the object.
We know that the volume of cylinder = πr²h

a rectangular garden is 115 * 90 m.it has two roads, each 6 m wide, running in middle of it, one parallel to its length and other parallel to its breadth.find the cost of constructing the roads at $ 100 per m
Step-by-step explanation:
so, the first road is 115 m long, the second is 90 m long.
we should be finished, if we multiply each road length by $100, right ?
well, not quite.
because the 2 roads overlap. for this overlap area we don't need to pay twice.
we have the choice : to which of the 2 roads do we assign the overlap area ?
let's "give" it to the longer road.
so, the cost for the longer road is simply
115 × 100 = $11,500
the cost for the shorter road is then without the overlap area (6 meters : the width of the other road)
(90 - 6)×100 = 84×100 = $8,400
in total the costs are
$11,500 + $8,400 = $19,900

(1, 4)
Answer:
Correct choices are:
(-1, 8)
(1, 4)
which would correspond to the second and fourth entries of your options
Step-by-step explanation:
Best way to solve this problem is to plug in x and y values for each ordered pair and see if these values result in a consistent equation. It is impossible to solve the equation since there are two unknowns and only one equation
Here is each ordered pair and resulting y value when x value is plugged in
(-1, 2) ==> y = 2, x = -1
6 - 2(-1) = 6 + 2 = 8
This is not equal to the given value of y =2. So incorrect
(-1, 8)
We figured out from above that when x = -1, y = 8 so this is a correct choice
(-2, 6) ==> x = -2, y = 6
6 - 2(-2) = 6 + 4 = 10
Does not match y-value; incorrect
(1, 4) ==> x = 1, y = 4
6 - 2(1) = 6 - 2 = 4
This matches the given value of y so correct choice

Determine an expression that produces a given resultant vector. Write an expression that can be used to produce factor be from vector a, and explain how you determine the expression
Expression to produce vector b: b = d - c, where d and c add to a. Find d and c using a's components, b is inverse of a.
What is vector ?
Vector is a term that refers colloquially to some quantities that cannot be expressed by a single number, or to elements of some vector spaces.
Suppose vector "a" is given and we want to determine an expression to produce vector "b". To do this, we need to find two vectors, "c" and "d", such that:
a = c + d
where c and d are the vectors that when added together produce vector a. The expression to produce vector b can then be represented as:
b = d - c
The expression can be determined by first finding the components of vector a, and then using these components to determine the components of vectors c and d. For example, if vector a is represented as:
a = <a1, a2, a3>
We can set c and d equal to:
c = <a1/2, a2/2, a3/2>
d = <a1/2, a2/2, a3/2>
So, the expression to produce vector b can be represented as:
b = d - c = <a1/2, a2/2, a3/2> - <a1/2, a2/2, a3/2> = <0, 0, 0>
Expression to produce vector b: b = d - c, where d and c add to a. Find d and c using a's components, b is inverse of a.

Let's say vector a is represented by the expression (a1, a2), and vector b is represented by the expression (b1, b2).
Then, the expression for the resultant vector (c1, c2) can be calculated as follows:
c1 = a1 + b1
c2 = a2 + b2
So the expression for the resultant vector is (a1 + b1, a2 + b2).
To determine an expression that produces vector b from vector a, you would need to know the relationship between the two vectors. If vector b is a scalar multiple of vector a, the expression for vector b can be represented as:
b = k * a
Where "k" is the scalar factor. If vector b is a vector that is in the opposite direction of vector a, the expression for vector b can be represented as:
b = -1 * a

What is an angle?
Two lines intersect at a location, creating an angle. An "angle" is the term used to describe the width of the "opening" between these two rays. Angles are frequently expressed in degrees and radians, a unit of circularity or rotation. We encounter angles frequently in life. Angles are used in the design of buildings, roadways, and sports venues by engineers and architects.
C,U and B are the angles and the c,u and b are the sides opposite to the angles C,U and B respectively.

Step-by-step explanation:
Given the equation sr = qut, we can solve for u by isolating it on one side of the equation. To do this, we divide both sides by qut. This gives us sr/qut = u. This means that u can be represented in terms of q, r, s, and t as sr/qut. This is the final result.
