Answer:
y = - [tex]\frac{2}{3}[/tex] x - 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
given
2x + 3y = 3 ( subtract 2x from both sides )
3y = - 2x + 3 ( divide through by 3 )
y = - [tex]\frac{2}{3}[/tex] x + 1 ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
• Parallel lines have equal slopes , then
y = - [tex]\frac{2}{3}[/tex] x + b ← is the partial equation
to find b substitute (3, - 4 ) into the partial equation
- 4 = - 2 + b ⇒ b = - 4 + 2 = - 2
y = - [tex]\frac{2}{3}[/tex] x - 2 ← equation of parallel line
During WW! mortars were fired from trenches 3 feet down The mortars had a velocity of 150 ft/s. Determine how long it will take for the mortar shell to strike its target?
In 0.02 seconds, the mortar shell will make contact with the target.
How to determine the time it will take the mortar shell to strike the targetThe formula for velocity, which is equal to distance / time, is used to calculate how long it will take to hit the target.
In the problem, the distance is 3 feet, and the velocity is given to be 150ft/s
therefore
150 = 3 / time
time = 3 / 150

What is the Perimeter of a Polygon?To find the perimeter of a polygon, sum all the side lengths of the polygon all together.
What is the Two-tangent Theorem?If two tangent segment of a circle are drawn to meet at a point outside the circle, the two-tangent theorem says they are congruent together, that is, they have equal length.
Applying the two-tangent theorem, the following side lengths that are missing as labelled in the diagram attached below are:
a = 13 cm
b = 9 cm
c = 5 cm
d = 8 cm
Therefore:
Perimeter of the polygon = 13 + a + b + 9 + 5 + c + d + 8

When conducting descriptive analyses or conducting an initial analysis of a sizable data set, a five-number summary is particularly helpful. The maximum and minimum values in the data set, the lower and upper quartiles, and the median make up a summary's five values.
Given, the five-number summary of Country A:
92, 110, 120, 160, 240
Then, we get
Minimum value = 92, First quartile = 110, Median = 120, Third quartile=160,

Which translation rule matches the transformation for congruent triangles?
The translation applied to the triangle is:
T(x, y) → (x +4, y - 5)
Sp the correct option is the first one.
Which is the rule of the translation from GHI to G''H''I''?To analyze the translation we only need to compare the coordinates of one of the vertices.
Let's see the vertex H.
The coordinates of H are (-4, 1)
The coordinates of H'' are (0, -4)

Cari is searching online for airline tickets. Two weeks ago, the cost to fly from boston to denver was $220. Now the cost is $295. What is the percent increase? What would be the percent increase if the airline charges an additional $50 baggage fee with the new ticket price?
The percent increase with the additional baggage fee for airline would be $125 / $220 x 100% = 56.82%.
What is meant by the term percentage?A number can be expressed as a fraction of 100 using a percentage. It may be computed by dividing the number by the total and multiplying by 100. It is commonly represented by the sign "%". The percentage of men, for instance, would be 25/100 x 100, or 25%, if there were 100 persons in all.
In a variety of areas, including statistics, finance, and education, percentages are often employed. For instance, in finance, percentage increase in stock prices are used to gauge a market's or company's success. In education, grades are frequently given as percentages to represent class marks.
How to solve?
The increase in the cost of the ticket is $295 - $220 = $75
The percent increase is $75 / $220 x 100% = 34.09%.
If the airline charges an additional $50 baggage fee, the new ticket price would be $295 + $50 = $345.
The increase in the cost of the ticket with the additional baggage fee would be $345 - $220 = $125.
The percent increase with the additional baggage fee would be $125 / $220 x 100% = 56.82%.

What is a function?
A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
This means that if the object x is in the set of inputs (called the domain) then a function f will map the object x to exactly one object f(x) in the set of possible outputs (called the codomain).
h(x) = 5x - 6
(h + h)(x) = h(x) in x. This means put the function in h(x)
so x = 5x - 6
so (h + h)(x) = 5(5x-6) -6
if x = 2,
we have (h + h)(2) = 5[5(2) -6] -6
In conclusion the expression 5[5(2) -6] -6 is equivalent to (h+h)(2)

What is the average rate of change of this function on the interval from x = 1 to x = 3? f(x)=10(2)x Enter your answer in the box.
Answer:
30
Step-by-step explanation:
The way to figure out the average rate of change is to divide the change in f(x) and divide that by the change in x. A formula for this is [tex]\frac{f(x_{1})-f(x_{2})}{x_{1}-x_{2}}[/tex]
1.) By this definition, we need to figure out our x1 and x2. We can say the x1 = 3 and x2 = 1
2.) Next, we plug it into the formula. We will get [tex]\frac{f(3)-f(1)}{3-1}[/tex].
3.) If we simplify, we will get 10(2)^3 - 10*2 divided by 2, which is equal to 10*4 - 10 = 30.

The rectangle that has side lengths of 5 units and 6 units is (b) the rectangle that has a perimeter of 22 units
How to determine the rectangle?The complete question is added at the end of this solution
From the complete question, we have the following parameters that can be used in our computation:
Side lengths = 5 units and 6 units
These side lengths can be represented as
Length = 5 units
Width = 6 units
The area of a rectangle is calculated as
Area = Length * Width
Substitute the known values in the above equation, so, we have the following representation
Area = 5 units * 6 units
Area = 30 square units
The perimeter of a rectangle is calculated as
Perimeter = 2 * (Length + Width)
Substitute the known values in the above equation, so, we have the following representation
Perimeter = 2 * (5 units + 6 units)
Perimeter = 22 units
