The point-slope form with a slope of 5/2 and a point of (4,-7) is 5x-2y=34.
What is line equation?In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10. Linear equations are classified into three types: point-slope, standard, and slope-intercept.
Here,
The slope of line perpendicular to the line y +6=-2/5(x-1)
m1=5/2
point=(4,-7)
y-y1=m(x-x1)
y+7=5/2(x-4)
2y+14=5x-20
5x-2y=34
The point-slope form for slope given as 5/2 and point as (4,-7) will be 5x-2y=34.

A Question 9 (2 points) Retake question
The equation g(x) = |-x-3| + 2 would reflect the function over the y-axis.
The required value of f(3) is 10.
What is a reflection across the y-axis?Reflection across the y-axis is defined as reflecting a point across they = x, the x-coordinate, and y-coordinate places, the line y = -x is the coordinates (-x, y).
So reflected across the y-axis: f(x) → f(-x),
⇒ (x,y) → (-x , y)
As per the given question,
f(x) = |x-3| + 2
f(-x) = |-x-3| + 2 = g(x)
Thus, the equation g(x) = |-x-3| + 2 would reflect the function over the y-axis.
The function f(x) is given in the question,
f(x) = 4x - 2,
To determine the value of f(3)
Substitute the value of x = 3 in the given function,
f(3) = 4(3) - 2
f(3) = 12 - 2
f(3) = 10
Thus, the required value of f(3) is 10.

Write the equation of 5x-y=15 after it is reflected in the y-axis and then translated (3 -1)
Answer: y=-5x-1. I need someone to tell me what translating equations is and how to get there.
The equation after the transformation is y = -5x - 1
How to determine the equation after the transformation?From the question, we have the following parameters that can be used in our computation:
Equation: 5x - y = 15
Make y the subject
So, we have
y = 5x + 15
The rule of reflection across the y-axis is
(x, y) = (-x, y)
So, we have the following equation
y = -5x + 15
The rule of translation by (3 -1) is
(x, y) = (x + 3, y - 1)
So, we have the following equation
y = -5(x + 3) + 15 - 1
Expand
y = -5x - 15 + 15 - 1
So, we have
y = -5x - 1
Hence, the equation is y = -5x - 1

liters/minute, where t is in minutes since the pump is started. if the holding tank contains 1000 liters of water when the pump is started, approximately how much water does it hold two hours later?
Approximately, water does it hold two hours later is = 248.72 liters
Given that,
The holding tank contains 1000 liters of water
Water does it hold two hours later,
Then,
1) Integrate the function, from t =0 to t = 120 minutes to obtain the number of liters pumped out in the entire interval, and
2) Substract the result from the initial content of the tank (1000 liters).
So
We can write,
Let us assume,
Integral of (6 - 6 [tex]e^{-0.13t}[/tex] ) dt ]from t =0 to t = 120 min
= 6t + 6 [tex]e^{-0.13t}[/tex] / 0.13
= 6t + 46.1538 6 [tex]e^{-0.13t}[/tex] ] from t =0 to t = 120 min
= 6*120 + 46.1538 e^(-0.13*120) - 0 - 46.1538
= 720 + 46.1538 (1.678) - 46.1538
= 720 + 77.44 - 46.1538 liters
= 751.28 liters
2) If the holding tank contains 1000 liters of water,
1000 liters - 751.28 liters = 248.72 liters
Therefore,
Approximately, water does it hold two hours later is = 248.72 liters

The ratio of yellow marbles to purple marbles was 13 to 4. If there were 102 marbles in the bag, how many were yellow marbles?
The number of yellow marbles based on the given ratio will be 78.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Suppose, the number of yellow marbles is Y while purple marbles are P.
As per the given,
The ratio Y/P = 13/4
Total Y + P = 102
(13/4)P + P = 102
13P + 4P = 408
17P = 408
P = 24
And, Y = 102 - 24 = 78
Hence "The number of yellow marbles based on the given ratio will be 78".

9. Sales: $50,000
Returns: $4,680
Net Sales: (a)
Cost of goods sold: $22,950
Gross profit: (b)
The gross profit of the Blog Inc would be $22,370.
What is gross profit?Gross profit is the profit of a company or an entity after subtracting all the costs that are related to manufacturing and selling its products or services. Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that Sales: $50,000
Returns: $4,680
Cost of goods sold: $22,950
Therefore,
Net Sales: 50,000 - 4,680
= 45,320
We can calculate the Gross Profit;
Gross Profit = (Net Sales – Cost of Goods Sold)
= ($45,320- $22,950)
= $22,370
Hence, the gross profit would be $22,370.

What is inequality?An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way.The majority of the time, size comparisons between two numbers on the number line are made.
Here, "Less than" and "Greater than" have new meanings.
Less-than sign is the symbol for such phrase.
14 - 3f > 2
adding 3f on both sides:
14 - 3f + 3f > 2 + 3f
14 > 2 + 3f
subtracting 2 on both sides:
14 - 2 > 2 + 3f - 2
12 > 3f
dividing 3 on both sides:

the mean score on a college placement exam is 500 with a standard deviation of 100. ninety-five percent of the test takers score below what value?
The value for which test score is below 95% percent for the given mean and standard deviation on a college placement is equal to 696.
As given in the question,
Given : 95% of the test takers score are below z.
z-score is given by,
z=(x-μ)/σ
Mean of the score 'μ' = 500
Standard deviation of the score ' σ' = 100
Z = 95%
= 0.95
P(z<Z) = 1-0.95
= 0.05
The value of z which corresponds to 0.05 in the table is equal to 1.96.
Substitute all the values we get,
z=(x-μ)/σ
⇒1.96 = ( x - 500 ) / 100
Multiply by 100 both the sides we get,
⇒ 196 = ( x - 500 )
⇒ x = 696
Therefore, the value for which test score is below 95% percent for the given mean and standard deviation is equal to 696.

The required linear equation that defines the dependent variable, p, in terms of the independent variable, t is p = 3t + 4.
Explain linear equation?A linear equation is a mathematical condition of the structure y=mx+b. including just a steady and a first-request (straight) term, where m is the slant and b is the y-catch. Sometimes, the above is known as a "straight condition of two factors," where y and x are the factors.
According to question:Let linear equation be p = at + b
Where a and b are constant.
On putting the values from the table,
4 = 0×a + b
b = 4
and,
7 = 1×a + b ⇒ a + b = 7
a + 4 = 7
a = 3

p = 3t + 4

Decide whether enough information is given to prove that the triangles are congruent using the HL Congruence Theorem. Explain.
Answer:
No
Step-by-step explanation:
You want to know if there is enough information to claim ∆PQT ≅ ∆SRT by the HL theorem.
HL theoremThe HL theorem tells you right triangles are congruent if they have one leg (L) and the hypotenuse (H) congruent.
Here, the triangles are not indicated as being right triangles, so the HL theorem cannot be applied.
__
Additional comment
There is not enough information here to permit the triangles to be declared congruent.
For congruence by any theorem, we'd need to know that angle T is the largest angle in each triangle, a condition not supported by the evidence.
Though rarely (if ever) seen in congruence discussions, a claim of SSA congruence can only be supported if the angle (A) is opposite the longest side. When the angle is 90°, this is called the HL congruence theorem. When the angle is known to be obtuse, it will always be opposite the longest side.
When the given angle is opposite the shortest of the two given sides, there are two possible triangles that can be constructed. Hence congruence cannot be guaranteed between two triangles with the same SSA dimensions.
