suppose the equation for line A is given by 2x-5y=15, if line A and B are parallel and the point (-10,3) lies on line B, then write the equation in slope intercept for line b.
Answer:
y=2/5x + 7
Step-by-step explanation:
First, you have to rewrite 2x-5y=15 to slop intercept form.
To do that you have to first subtract 2x from both side to cancel it out.
2x- 2x-5y= 15 -2x.
-5y= -2x+15
Next, you divide 5 on both side to leave the y by itself.
y= -2x/-5 + 15/-5
Simplify
y= 2/5x + (-3) 2/5 is our slope
Now that we found the slope, we need to the y-intercept of line b
y=2/5x + b
To find the y-intercept, we substitue x and y with the coordinates (-10,3)
3= 2/5(-10) +b
Now we just solve for b
3= -4 +b
3-(-4) = b
7=b
Now we have identified that 7 is the y intercept
The full equation is y= 2/5x +7
I hope this helped :)
Use the number line below, where RS = 5y +3, ST = 3y + 4, and RT = 10y - 3.
a. What is the value of y?
b. Find RS, ST, and RT.
Answer:
(a). y = 5
(b). RS = 28
ST = 19
RT = 47
Step-by-step explanation:
(a). There are three points R, S and T on a number line.
Therefore, RT = RS + ST -------(1)
Since, RT = 10y - 3
RS = 5y + 3
ST = 3y + 4
By substituting these values in the equation (1)
10y - 3 = (5y + 3) + (3y + 4)
10y - 3 = 8y + 7
10y - 8y = 7 + 3
2y = 10
y = 5
(b). RS = 5y + 3
= 25 + 3
= 28
ST = 3y + 4
= 15 + 4
= 19
RT = 10y - 3
= 50 -3
= 47
The formula A = 1/2 S^2 expresses the area of an isosceles right
triangle in terms of the length, s, of a leg of the triangle.
Which equation expresses the length of a leg of an isosceles right
triangle in terms of the area?
Answer:
[tex]s = \sqrt{2a} [/tex]
Step-by-step explanation:
A = 0.5S^2
2A = S^2
Therefore,
[tex]s = \sqrt{2a} [/tex]
To express the length in terms of the area, is an illustration of change of subject of formula.
The equation that express S in terms of the area is: [tex]S =\sqrt{2A}[/tex]
Given that:
[tex]A = \frac 12S^2[/tex]
First, multiply both sides by 2
[tex]2 \times A = \frac 12S^2 \times 2[/tex]
[tex]2 \times A = S^2[/tex]
[tex]2A = S^2[/tex]
Take positive square roots of both sides
[tex]\sqrt{2A} = \sqrt{S^2[/tex]
[tex]\sqrt{2A} = S[/tex]
Rewrite the equation as:
[tex]S =\sqrt{2A}[/tex]
Hence, the equation that express S in terms of the area is: [tex]S =\sqrt{2A}[/tex]

write a polynomial of least degree with roots 6 and. -8
Answer:
y = x² + 2x - 48
Step-by-step explanation:
Given the roots of the polynomial are x = 6 and x = - 8 , then the corresponding factors are
(x - 6) and (x + 8) and the polynomial is the product of the factors, that is
y = (x - 6)(x + 8) ← expand using FOIL
y = x² + 2x - 48
Which of these is a simplified form of the equation 9y + 6 = 9 + 2y + 2y?
Answer:
y=3/5
Step-by-step explanation:
9y+6=9+2y+2y
9y+6=9+4y
9y-4y=9-6

Find the domain and range of each relation (use interval notation). Then determine if each relation is one-to-one.
(-2, 8) (9, 10) (1,7) (3, 9) (10, 12)
Function
Not a Function
Answer: function
Step-by-step explanation: To determine whether the relation shown here
is a function, remember that a relation is a function if each x term
corresponds to exactly one y term.
In the data set show, each x term, -2, 9, 1, 3, and 10 appears only once.
This means that each x term corresponds to exactly one y term.
So yes, the relation is a function.
Identify the hypothesis of the statement. If a number is negative, then the number is less than zero. A) a number is negative B) a number is positive C) the number is less than zero D) the number is greater than zero
Answer: A) a number is negative
Step-by-step explanation:
A conditional statement is written as:
If P, then Q.
Where P is the hypothesis and Q the conclusion.
In this case, we have:
If a number is negative, then the number is less than zero.
then we have:
P = a number is negative.
Q = the number is less than zero.
Then the hypothesis will be "a number is negative"
The correct option is A.
Answer:
number is negative

On a baseball field the pitcher's mound is 60.5 ft away from home plate. Second base is 127.28 ft from home plate. Is the pitcher's mound the midpoint of home plate and second base? Explain your reasoning
Answer and Step-by-step explanation: Midpoint is the middle point in a segment line, i.e., it is at the center of a segment line.
On a baseball field, distance between home plate and second base is 127.28ft. The midpoint will be:
midpoint = [tex]\frac{127.28}{2}[/tex]
midpoint = 63.64ft
To be the midpoint, pitcher's mount must be 63.64ft away from the home plate. Since it's less than that, pitcher's mount is not the midpoint between home plate and second base.

Carla needs to rent storage space for some of her belongings. She paid a one-time original storage fee of $25.00, and now pays $36.00 each month (m). Which answer choice shows an expression that represents the total amount Carla has paid after a certain number of months (m)?
Answer:
TC = 36t + 25
Step-by-step explanation:
The amount paid by Carla as a storage fee or fixed cost = $25
Monthly rent or variable cost = $36
Let the number of months = t
Now we have to find the expression that represents the total cost. Below is the formula to find the expression.
Total cost = Variable cost + Fixed cost
Total cost = 36t + 25
TC = 36t + 25

find the roots of the quadratic equation using factoring. 6m^2 - 23M + 10 = 0
m₁ = 10/3
m₂ = 1/2
Step-by-step explanation:6m² - 23m + 10 = 0
6m² - 2m - 20m + 10 = 0
3m(2m - 1) - 10(2m - 1) = 0
(3m - 10)(2m - 1) = 0
3m - 10 = 0 =>3m = 10 => m₁ = 10/3
2m - 1 = 0 => 2m = 1 => m₂ = 1/2
What is the relationship between the 8’s in 8,809
Answer:
Their place values
Step-by-step explanation:
On eight is in thousands while the other is in hundreds
Answer:
"8" on the left is ten times the value of the "8" on the right
Step-by-step explanation:
I am going to assume that the comma " , " denotes divisions of "thousands" and not the European system where the comma represents a decimal point.
(refer to attached for definitions of place values)
we can see that for the number 8,809 :
1) the 8 on the left is in the thousands place and hence represents 8000.
2) the 8 on the right is in the hundreds place and hence represents 800.
in order to find the relative order of difference between the two digits, we simply we divide the value of the two digits:
8000 ÷ 800 = 10
Hence the "8" on the left is ten times the value of the "8" on the right
