Answer:
x > 7/8 and the picture is below.
Step-by-step explanation:
To find the answer, you plug in the values for x. Nothing less than one in the set of given values, works. 1 works, 9/4 works, and 5/2 works. But everything else doesn't. Or, you could simply divide both sides by 2 to get x alone. That makes x>7/8. Meaning 7/8 doesn't work, but anything above it, does. So you could just look for the ones that are greater than 7/8.

Answer:
Assuming the question is: 3 + 1 16 [I see no "working below."
Step-by-step explanation:
3 + 1 16
48/16 + (16/16 + 1/16) [Make all numbers into fractions using 16 as the denominator. E.g. 48/16 = 3.
Add: 48/16 + (16/16 + 1/16)

Calculate the slope of the line for Graph B.
Answer:
-1
Step-by-step explanation:
rise = -2
run = 2
Slope = rise / run
= -2/2 = -1
Since also the angle made by the line and x axis in anti clockwise direction is > 90° the slope will be-ve .
Answer:
Slope = -1
Step-by-step explanation:
You are provided with two points on the line (-5, 7) and (1,1).
[tex]Slope = \frac{y_{2} -y_{1}}{x_{2} -x_{1}}[/tex]
[tex]Slope = \frac{7-1}{-5-1} =\frac{6}{-6} =-1[/tex]
what are the values of the variables
Answer:
21
Step-by-step explanation:
we know that according to the isosceles triangle theorem, that the angles of the triangle are 90, 2x+3, 2x+3
from the triangle angle sum theorem, we know that 4x+6 = 90
solving, we get 4x=84, x=21
Answer:
isosceles + a right angle, so both angles at the bottom are the same and equal to (2x+3).
so we have 180 degrees = 90 + (2x+3) + (2x+3)
so x = 21
Module 3 DBA: What key features can be identified from graphs of polynomials of higher-
degrees and explain how the key features can be used sketch the graph of the polynomial
function? Remember to include how solutions are represented.
to be honest i dont remember srry
Answer:
Polynomials are algebraic expressions that contain more than two terms. AN example would be: f(x) = x^3 + x^2 + x +1. This equation contains three terms, with the 3rd degree as its highest term. It also means that the graph passed three x-intercepts. This depends in the highest degree. So, the first thing you do is plot the intercepts because for sure, the graph will pass there.

Answer:
HI! If this helps plz brainlist
Step-by-step explanation:
Rewrite 8 x 3 8 x 3 as (2x)3 ( 2 x ) 3 . Rewrite 27 as 33 . Since both terms are perfect cubes, factor using the difference of cubes formula, a3−b3=(a−b)(a2+ab+b2) a 3 - b 3 = ( a - b ) ( a 2 + a b + b 2 ) where a=2x a = 2 x and b=3 . Simplify.

If you need to ask any questions, please let me know.What is the result when this equation is solved for y?
4x²+10x-2y=6
Answer:
B. y = 2x² + 5x - 3
Step-by-step explanation:
[tex]4x^2+10x-2y=6\\\\4x^2+10x-2y-4x^2-10x=6-4x^2-10x\\\\-2y=-4x^2-10x+6\\\\\frac{-2y}{-2}=\frac{-4x^2-10x+6}{-2}\\\\y=2x^2+5x-3[/tex]
The result when the equation is solved for y is y = 2x² + 5x - 3.
To solve the equation 4x² + 10x - 2y = 6 for y, follow these steps:
Step 1: Move all terms containing y to one side of the equation:
4x² + 10x - 6 = 2y
Step 2: Divide both sides of the equation by 2 to isolate y:
(4x² + 10x - 6) / 2 = y
Step 3: Simplify the right side of the equation:
y = 2x² + 5x - 3
So, the result when the equation is solved for y is y = 2x² + 5x - 3.

What is Perfect square
Answer:
A perfect square is an integer that results in another integer when square rooted.
Step-by-step explanation:
For example:
16 is a perfect square because [tex]\sqrt{16}[/tex] = 4.
16 and 4 are both integers
Also, notice that 4 x 4 = 16
Answer:
A perfect square is a number that can be multiplied together by the same numbers/digits/values.
Step-by-step explanation:
Examples:
√25
5 times 5 is 25 thus √25 is a perfect square
√144
12 times 12 is 144 thus √144 is a perfect square

Answer:
AB = 2.625
Step-by-step explanation:
BC is an angle bisector and divides the opposite sides into segments that are proportional to the other 2 sides , that is
[tex]\frac{CA}{CD}[/tex] = [tex]\frac{AB}{BD}[/tex] , that ia
[tex]\frac{6}{10}[/tex] = [tex]\frac{AB}{7-AB}[/tex] ( cross- multiply )
10 AB = 6(7 - AB) ← distribute
10 AB = 42 - 6 AB ( add 6 AB to both sides )
16 AB = 42 ( divide both sides by 16 )
AB = 2.625
