Fill in the table using this function rule.
y=26-4x
The complets table of values for the function rule
x 1 2 4 6
y 22 18 10 2
Completing the table of values for the function ruleFrom the question, we have the following parameters that can be used in our computation:
y = 26 - 4x
The missing y values are at x = 1, 2, 4 and x = 6
Substitute the known values in the above equation, so, we have the following representation
y = 26 - 4(1) = 22
y = 26 - 4(2) = 18
y = 26 - 4(3) = 10
y = 26 - 4(6) = 2
So, the missing values are 22, 18. 10 and 2

8 - 4a = -2a
7th Grade Linear Questions
Answer:
a = 4
Step-by-step explanation:
So your goal here is to get the variable on just one side, so add 4a to both sides. This cancels out the 4a on of of the sides and puts a on the other side. The new equation is 8 = -2a + 4a. Combine like terms to get 8 = 2a. Divide both sides by 2 to get a = 4. You can check your work by replacing a with 4:
8 - 4(4) = -2(4)
8 - 16 = -8
-8 = -8
Since the final result is true, (-8 does equal -8,) a = 4.

Answer:
23/2
Step-by-step explanation:
first turn the mixed number into a fraction:
2*10=20
20+3=23
so, we get 23/2
The value of the mixed number in the simple form will be 23/2.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the mixed number is 10³/₂. The simplest form will be written as,
first, turn the mixed number into a fraction:
2 x 10=20
20+3=23
The fraction will be 23/2.
Hence, the value of the mixed number in the simple form will be 23/2.

Urgent help on math plz
Answer:
x = 14
Step-by-step explanation:
First, organize your work by showing that lines are similar
Line KV is similar to line RV
Line UV is similar to line LV
etc, etc.
=========================================
Now notice that line KV and line RV have the numbers 9 and 18 accordingly
and notice that it's an x2 difference.
==============================================
Now apply the same thing to line UV and LV and divide 26 by 2
That gets us 13
=======================================
Now plug 13 into the equation (2x - 15)
2x - 15 = 13
==========================================
Now solve for X
2x - 15 = 13
Add 15 to each side
2x − 15 + 15 =13 + 15
2x = 28
Divide both sides by 2
2x / 2 = 28 / 2
x = 14

9. Find the slope. Make sure to reduce.
Answer:
-2.
Step-by-step explanation: Since you are going left its a negative slope.
Answer:
-2
Step-by-step explanation:
To find the slope we can do rise over run or y/x
y/x = -2/1 = -2
So that is the slope
And if you need the slope-intercept, it will be -2...and the formula will be
y = -2x - 2
But the slope is -2.

Find the perimeter of a parallelogram with coordinats (2,10), (4,2), (7,8)
and (-1,4).
P = 2(a+b)
a = side
b = base
The perimeter of the parallelogram is [tex]\sqrt[2]{29}+ \sqrt[6]{6}[/tex]
Calculation of the perimeter of the parallelogram:Since the coordinates are (2,10), (4,2), (7,8) and (-1,4).
Now for determining the perimeter first we have to calculate the distance of AB and BC
So,
For AB, the distance is
[tex]= \sqrt{(2-7)^2 + (10-8)^2}\\\\ = \sqrt{29}[/tex]
Now
For BC, the distance is
[tex]= \sqrt{4-7)^2 + (2-8)^2}\\\\ = \sqrt{54}\\\\= 3\sqrt{6}[/tex]
Now the perimeter is
= 2(AB + BC)
= [tex]2(\sqrt29 + 3\sqrt 6)[/tex]
= [tex]\sqrt[2]{29}+ \sqrt[6]{6}[/tex]
Therefore, The perimeter of the parallelogram is [tex]\sqrt[2]{29}+ \sqrt[6]{6}[/tex]

Answer:

Step-by-step explanation:
To find the length of side A, we'll apply the Pythagorean Theorem Formula.
[tex]\bf \boxed{\bf AB= \sqrt{ (AC )^{2} - ( BC)^{2} } }[/tex]
Where, AC = 10 (Hypotenuse) and BC = 6.
[tex]\bf a = \sqrt{(10) ^{2} - {6}^{2} } [/tex][tex]\bf a = \sqrt{100 - 36} [/tex][tex]\bf a = \sqrt{64} [/tex][tex]\bf a = 8[/tex]Therefore, option C is the answer.
