Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio.
A(-6, 9), B(2, 1); Ratio 5 to 3
Answers
Answer:
The coordinates of the point P = (x, y) = (-1, 4)
Step-by-step explanation:
Let the coordinates of P be (x, y)
(x₁, y₁) = (-6, 9)(x₂, y₂) = (2, 1)ratio = m:n = 5:3Using the section formula
x = [(mx₂ + nx₁)] / [(m+n)]
= [5(2)+3(-6)] / [5+3]
= [10-18] / [8]
= -8/8
= -1
y = [(my₂ + ny₁)] / [(m+n)]
= [5(1)+3(9)] / [5+3]
= [5+27] / [8]
= 32/8
= 4
Therefore, the coordinates of the point P = (x, y) = (-1, 4)

Apply the Negative Exponent Rule. Negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents.
Answer:
6³⁰
__________________________________________________________
We are given the expression:
[tex]\frac{(6^{-4})^{-9}}{6^{6}}[/tex]
Simplifying the expression
We can multiply the 2 exponents on the numerator to get:
[tex]\frac{6^{36}}{6^{6}}[/tex]
We can switch the sign of the exponent on the denominator to get it's reciprocal
[tex]{6^{36}}*6^{-6}[/tex]
Since the bases are the same, adding the powers
[tex]{6^{36-6}}[/tex]
[tex]{6^{30}}[/tex]
Hence, the given expression can be simplified to 6³⁰

How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of apples = A
Number of bananas = B
Given that,
Apples and bananas at the store in a ratio of 3 apples to 4 bananas.
So,
A/B = 3/4
And,
A + B = 35
By substitution,
4(35 - B) = 3B ⇒ B = 20
And,
A = 35 - 20 = 15
Hence "A total of 15 apples and 20 bananas has been bought".

Oscar is selling tickets to a school play. Adult tickets cost $8 and student tickets cost $7. If he collected $245 by selling 34 tickets, how many adult and student tickets did he sell?
Answers
Answer:
Adult= 7 tickets
student= 27 tickets
Step-by-step explanation:
Step one:
let adult tickets be x
and students be y
Adult tickets cost $8 and
student tickets cost $7
So
[tex]8x+7y=245-----------1\\\\x+y=34-----------2[/tex]
Step two:
from equation 2
x=34-y
put the value of x in equation 1
[tex]8(34-y)+7y=245\\\\272-8y+7y=245\\\\272-y=245\\\\-y=245-272\\\\-y=-27\\\\y=27[/tex]
put y= 27 in equation 1
[tex]x+27=34\\\\x=34-27\\\\x=7[/tex]

Answer:
It is true
Step-by-step explanation:
Convert to slope-intercept form:
2x-y=6
-y=6-2x
y=-6+2x
y=2x-6
Since y=mx+b is the form we want, then b=-6, making the statement true.
Answer:
true
Step-by-step explanation:
you switch the 2x to the other side to get -y = 2x + 6
then you multiply everything by -1 to get y = -2x-6

1 1/5 to an improper fraction is -6/5
Now rewrite the inequality as,
81 - 6/5x [tex]\leq[/tex] 55 Subtract 81 from both sides
-81 -81
-6/5x [tex]\leq[/tex] -26 Multiply both sides of the inequality by 5
-6x [tex]\leq[/tex] -130 Divide both sides by -6 and the sign will me flip since your divide both sides by a negative number.

First, you have to find the slope.
As x increases by 3, y increases by 6 so the slope is rise/run so it would be 6/3 and simplify so it’s gonna be 2.
b of the y=ax+b is y-int so it’s a y value when x is 0 so in this case, 6.
B: y=-2x+8
First, you have to find the slope.
As x increases by 2, y decreases by 4 so the slope would be -4/2 and simplify so it’s gonna be -2.
b is equal to the y-value when x is 0 so in this case, 8.
C: y=3x+4
First, you have to find the slope.
As x increases by 2, y increase by 6 so the slope would be 6/2 and simplify so it’s gonna be 3.
When u solve for b, first, at this point, you have the equation y=3x+b so you’re gonna plug in random point into it so for ex, 2 for x and 10 for y(as it shows on table) and you can get 4.
D: y=-1/2x+6
First, you have to find the slope.
As x increases by 4, y decreases by 2 so the slope would be -2/4 and simplify so it’s gonna be -1/2.
When u solve for b, first, at this point, you have the equation y=-1/2x+b so you’re gonna plug in random point into it so for ex, 8 for x and 2 for y(as it shows on table) and you can get 6.
