If Y is the midpoint of XZ, Y is located at (3, -1), and 2 is located at (Il, -5), find the coordinates of X. If anyone answers this if you could give how you did it I would appreciate it. Thank you!
Answer:
i think you mean Z equals 2, so i'll work from there,
the difference between y(3,-1) and (11,5) is (8,6), so you only have to subtract y points by this
and then you get X equals (-5,-7)

Answer:
B. 80
Step-by-step explanation:
According To Question, We Have
(180,14) (120,8) (? , 4) (220,18)
it Clearly Visible That ( 180*a+b=14 ) only Possible when we Put a=1/10 & b=-4. Thus, (180*1/10)-4 ⇔ 18-4 = 14Same For All (120*a+b=8)Thus, (120*1/10)-4 ⇔ 120-4 = 8
Now (?*1/10)-4=4 solve it .
Thus, ?*1/10=8⇔?=80 is Our Missing Number .
Evaluate the following expression. You should do this problem without a calculator. log4 4 A. 4 B. C. 8 D. 1 SUBMIT
Given:
The given expression is:
[tex]\log_44[/tex]
To find:
The simplified value for the given expression.
Solution:
According to the property of logarithm,
[tex]log_aa=1[/tex]
We have,
[tex]\log_44[/tex]
Here, the base of the logarithm is 4 and the value inside the log is also 4, since these two values are same therefore the value of this expression is 1 by using the above property of logarithm.
[tex]\log_44=1[/tex]
Hence, the correct option is D.
By evaluating log4 4 without a calculator, we discover that it is equal to 1.
Which equation in point-slope form contains the point (4, –1) and has slope 3?
y + 1 = 3(x – 4)
y – 4 = 3(x + 1)
y – 1 = 3(x + 4)
y + 4 = 3(x – 1)
Answer:
y+1=3(x-4)
Step-by-step explanation:
Hi there!
We are given a slope of 3 and a point (4,-1).
We need to find the equation of the line in point-slope form
Point-slope form is given as y-y1=m(x-x1), where m is the slope, and (x1,y1) is a point
We have all of the needed information to substitute into the formula
First, let's label the values of everything to avoid any confusion
m=3
x1=4
y1=-1
now substitute into the formula *remember, the formula has SUBTRACTION, and we have a NEGATIVE number, so we'll end up subtracting a negative*
y--1=3(x-4)
simplify
y+1=3(x-4)
That's it!

Identify the explicit function for the sequence in the table x 1,2,3,4,5 y 9,14,19,24,29
Answer:
[tex]a_{n}[/tex] = 5n + 4
Step-by-step explanation:
There is a common difference between the consecutive terms of y
29 - 24 = 24 - 19 = 19 - 14 = 14 - 9 = 5
This indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 9 and d = 5 , then
[tex]a_{n}[/tex] = 9 + 5(n - 1) = 9 + 5n - 5 = 5n + 4

B(x, y) = (-2, -2)
Step-by-step explanation:
Given: AB: AC (m₁: m₂) = 1 : 2, A (x₁, y₁) = (-5, 2) and B(x₂, y₂) = (4, -10)
To find: Coordinates of B (x, y)
Using section formula:
Therefore Coordinates of B (x, y) is (-2, -2).

Lucia is making blackberry jam. She starts with 25 cartons of blackberries. After making 9 jars of jam, she has 10 cartons of blackberries left. Lucia's jars all have the same capacity. Select true or false for each statement.
Answer:
A = true
B = false
C = false
D = True
Step-by-step explanation:
Cartons of blackberries = 25
Jars of blackberry jam made = 9
Cartons of blackberries left = 10
Cartons of blackberry used = Cartons of blackberries - Cartons of blackberries left
= 25 - 10
= 15
Cartons of blackberry used = 15
Cartons of blackberry used per jam = Cartons of blackberry used / Jars of blackberry jam made
= 15/9
= 5/3
A = true
15 jars of blackberry = Cartons of blackberry used per jam × jars of black berry made
= 5/3 × 15
= 75/3
= 25 cartons of blackberry
B = false
She can make 15 jars of blackberry jam using 25 cartons of blackberry
C = false
Cartons of blackberries left = 10
Number of blackberry jam made with 10 cartons of blackberry = Cartons of blackberries left / Cartons of blackberry used per jam
= 10 ÷ 5/3
= 10 × 3/5
= 30/5
= 6

Answer:
(6x + 5)(x + 2)
Step-by-step explanation:
x coefficients must multiply to 6
so 6 * 1 or 2*3
10 must be 5*2 or 1* 10
(6x + 5)(x + 2) = (6x² + 12x + 5x + 10) = 6x² + 17x + 10
For the triangles to be similar by the SSS similarity theorem, what must be the value of y?
18
20
24
26
Answer:
20
Step-by-step explanation:
Took the cumulative exam on Edge
The value of y in the given similar triangles is 20.
What are the similar triangles?Two triangles are said to be similar if their corresponding angles are congruent to each other and the corresponding sides are in equal ratios.
Given are two triangles, we need to find the value of y so that the triangles be similar by SSS rule,
If the figures are similar by SSS Similarity Theorem, then the ratio of its corresponding sides must be proportional,
So,
14/28 = 10/y
y = 20
Hence, the value of y in the given similar triangles is 20.
