Through: (-5,4), Parallel to y= -6/7x +3
Answer:
there.
Step-by-step explanation:
The given line, y = 4x - 1, has a slope of 4. Thus, the new line, being parallel to the given line, also has a slope of 4. The equation y - k = m(x - h)^2 becomes y - 7 = 4(x + 3)^2 when -3 is substituted for h, 7 for k and 4 for m.

You had a lot of spare time this summer because of quarantine, so you and four family members took a 5-day white-water rafting and hiking trip. During your 5-day trip, 2 days were spent rafting. If the rafting trip covered a distance of 60 miles and you spent 8 hours rafting each day, how many miles did you raft each hour?
Answer:
3.75 miles per hour
Step-by-step explanation:
Given that:
Number of days spent rafting = 2 days total distance covered during rafting = 60 miles
Time spent rafting per day = 8 hours
Number of miles raft per hour:
Total number of raft hours over the 2 days = (8 * 2) = 16 hours
Total raft distance over the 2 days = 60 miles
Raft miles per hour :
Total raft distance / total number of raft hours
60 miles / 16 hours
= 3.75 miles per hour

how are the original coordinates related to the coordinates after the translation
This coordinate plane represents the entire botanical garden where Vincent works. The rectangular figure on the coordinate plane is the original position of the rose garden. Vincent wants to slide the rose garden two yards east and four yards south. In this activity, you’ll help Vincent find the coordinates of the new rose garden.
Answer:
The x-coordinates of the translated figure are 2 more than the original x-coordinates. The y-coordinates of the translated figure are 4 less than the original y-coordinates.
Step-by-step explanation:
Answer:
Eastward translation of the rose garden will move it in the positive x-direction. So, the integer that represents a change of two yards east is +2.

Identify the range of the function shown in the graph.
A. 0 ≤ y ≤ 8
B. -6 ≤ x ≤ 6
C. y > 0
D. y is all real numbers.
Answer:
[tex]0\leq y\leq 8[/tex]
Step-by-step explanation:
because it cant go below x-axis with is y = o and nothing above 8
The function can produce any y-value between 0 and 8, including both 0 and 8 (option a).
The range of a function refers to the set of all possible output values, or y-values, that the function can produce. To identify the range of the function shown in the graph, we need to determine the highest and lowest y-values that the graph reaches.
Looking at the graph, we can see that the highest point on the graph is at y = 8, and the lowest point is at y = 0. Therefore, the range of the function is from y = 0 to y = 8.
In other words, the function can produce any y-value between 0 and 8, including both 0 and 8. We can express this range using interval notation as [0, 8].
So, the correct answer is option A: 0 ≤ y ≤ 8.

Answer:
y = 1/3x + 3
Step-by-step explanation:
Slope form of a equation: y = mx + b. The slope is 1/3, so y = 1/3x + b
Solve for b by plugging the (x, y) coordinate into the equation.
y = 1/3x + b
2 = 1/3(-3) + b
2 = -3/3 + b
2 = -1 + b
b = 3
So your answer is y = 1/3x + 3

Answer:
19.87301587
Step-by-step explanation:
Answer:
Step-by-step explanation:
Ok, so you would use PEMDAS, which is the correct order in which you would need to solve an equation. The idea is that the operations that come first would have to be solved first.
If you don't know it, PEMDAS is:
Parentheses
Exponents
Multiplication/division
Addition/subtraction
In this case, you would need to solve the parentheses. (7x9) is 63.
It would be rewritten as 4x5-8/63
There are no exponents, so you can skip the next operation.
Then you would do multiplication next, which would be 4x5 = 20
The equation would be rewritten as 20-8/63
-0.126984127 is -8/63
Lastly, 19.8730159 is the result of 20-0.126984127

What is the perimeter of a polygon with vertices at (-3, 1), (5, 1), (-3, 4), (5, 4)?
Answer:
The perimeter of the polygon is 22.
Step-by-step explanation:
Let [tex]A(x,y) =(-3,1)[/tex], [tex]B(x,y) = (5,1)[/tex], [tex]C(x,y) = (-3, 4)[/tex] and [tex]D(x,y) =(5,4)[/tex] the vertices of the polygon. From Geometry we know that number of side of polygons equals their number of vertices, then we notice that a quadrilateral is here. In addition, we conclude that such quadrilateral is a rectangle:
1) [tex]x_{A} = x_{C}[/tex]
2) [tex]x_{B} = x_{D}[/tex]
3) [tex]y_{A} = y_{B}[/tex]
4) [tex]y_{C} = y_{D}[/tex]
Hence, we find that [tex]AB = CD[/tex] and [tex]AC = BD[/tex].
Then we find all lengths of the rectangle by Pythagorean Theorem:
[tex]AB = \sqrt{[5-(-3)]^{2}+(1-1)^{2}}[/tex]
[tex]AB =8[/tex]
[tex]AC = \sqrt{[(-3)-(-3)]^{2}+(4-1)^{2}}[/tex]
[tex]AC = 3[/tex]
By Geometry, we conclude that [tex]CD = 8[/tex] and [tex]BD = 3[/tex].
Then, the perimeter of the rectangle ([tex]p[/tex]), dimensionless, is defined by the following formula:
[tex]p = 2\cdot (s+l)[/tex] (Eq. 1)
Where:
[tex]s[/tex] - Shortest length, dimensionless.
[tex]l[/tex] - Longest length, dimensionless.
If we know that [tex]s = 3[/tex] and [tex]l = 8[/tex], then the perimeter of the rectangle is:
[tex]p = 2\cdot (3+8)[/tex]
[tex]p = 22[/tex]
The perimeter of the polygon is 22.

Write a number in which the value of the digit 4 is 1/100 of the value of the digit 4 in 140.37. Explain how you know the number you wrote meets the criteria.
Answer:
0.4
Step-by-step explanation:
1/100 of the value of the digit 4 in 140.37
4 in that number is Tens place value.
This mean , 4 × 10 = 40
Hence, 1/100 of 40 is :
40 × 1/100

[tex] \boxed{ \sf{Selling \: price \: = \: Rs \: 1638}}[/tex]
Step-by-step explanation:
Given :Cost price of a electric fan ( CP ) = Rs 1560Profit percent = 5 %To find :Actual profit = ?Selling price = ?Solution :Finding the selling price of a fan ( SP ) :
[tex] \boxed { \sf{SP = \frac{CP(100 + profit \: \%)}{100} }}[/tex]

[tex] \sf{↦SP = \frac{1560 \times 105}{100}} [/tex]
[tex] \sf{↦ \: SP = \frac{163800}{100} }[/tex]
[tex] ↦ \boxed{ \sf{SP = Rs \: 1638}}[/tex]
Now, We have :
Selling price of a electric fan ( SP ) = Rs 1638Cost price of a electric fan ( CP ) = Rs 1560Finding the actual profit :
[tex] \boxed{ \sf{Actual \: profit \: = \: Selling \: price \: - \: Cost \: price}}[/tex]
[tex] \sf{↦ \: Actual \: profit \: = \: Rs \: 1638 - \: Rs\: 1560}[/tex]
[tex] \boxed{ \sf{↦ \: Actual \: profit \: = \: Rs \: 78}}[/tex]

Which of these functions are linear ?
Answer:
E
Step-by-step explanation:
A function that is linear is a straight line. A linear function can be found using [ y = mx + b ]
F shows an example of a quadratic function. A quadratic function can be found using [ f(x) = ax² + bx + c ]
Best of Luck!
[tex] \LARGE{ \underline{ \blue{ \bf{Required \: answer:}}}}[/tex]
The answer is E because the graph of linear equation is a straight line whereas the graph of a quadratic equation is a parabola opening upwards or downwards depends upon the coefficient of a in standard form : ax² + bx + c.
Linear equation have atmost 1 zero. This we can determine through the graph.Quadratic equation have atmost 2 zeroes and the no. of times it intersect with x-axis determines the no. of zeroes of the quad. equation.#CarryOnLearning
Alexia ran three laps around her neighborhood. Each lap is 1 and StartFraction 3 over 8 EndFraction miles. Which is the best estimate of the number of miles that Alexia ran?
2 miles
3 and one-half miles
4 and one-half miles
6 miles
Answer:
4 and one-half miles
Step-by-step explanation:
The answer closest to the correct answer is 4 and one-half miles.
To get the answer, you multiply 3 times the length of one lap which is 1 and [tex]\frac{3}{8}[/tex] miles. To multiply the fraction, you take 3 times the top number in the fraction. So 3 x 1 [tex]\frac{3}{8}[/tex] = 3 [tex]\frac{9}{8}[/tex]. The fraction can actually be reduced to 1 and [tex]\frac{1}{8}[/tex] miles. So you're total correct answer is 4 and [tex]\frac{1}{8}[/tex] miles.
The second selection is 3 and [tex]\frac{1}{2}[/tex] which can also be written as 3 and [tex]\frac{4}{8}[/tex] to make it easier to determine which answer is correct. The second answer is therefore [tex]\frac{5}{8}[/tex] shorter than the correct answer.
The third selection is 4 and [tex]\frac{1}{2}[/tex] which can be written as 4 and [tex]\frac{4}{8}[/tex] so it is only [tex]\frac{3}{8}[/tex] longer than the correct answer. So this selection is the closest to the actual miles ran.
