Answer:
yes
Step-by-step explanation:
see attached graph - there are two real roots for y=2x^4-6x^2+10x-7
so 2x^4-6x^2+10x-7 can be expressed as:
(x - root1)(x - root2)(2x^2+Bx+C)
Answer:
Yes, it can be.
Step-by-step explanation:
Using solver program, the expression 2x^4-6x^2+10x-7 has:
two real roots at x≈-2.3888 and x≈1.1424
and
two complex roots at x≈0.62321 - 0.94559 i and x≈0.62321 + 0.94559 i
Because it has two real roots, the expression can be simplified.

Answer:
y < 5x + 5
Step-by-step explanation:
find slope and y-intercept first:
for slope I used the formula with these two points: (0,5) and (-1,0) and the y-intercept can be seen at (0,5)
so equation is y = 5x + 5
but we need to select an inequality symbol, because line is dashed it must be either > or <
I used the point (0, 0) to determine the sign:
is this true or false? 0 > 5(0) + 5 False
so the sign must be <
Check: is this true or false? 0 < 5(0) + 5 True
2. A line passes through points (-1,-2) and (1,4). What is the equation of the line? TI
Answers
= 6/-3 = -2 = m. It's negative because as x increases, y decreases
plug that into the point slope formula, with either point. generally use the most simple point
y-h= m(x-k) where m= -2 and (k,h) = (2,-2)
y+2 = -2(x-2)
simply if you want
Y = -2x +4 -2 = -2x +2
or
2x +y = 2

How do we represent a percent in a equation
Answers
Answer: heres an example
Step-by-step explanation:Convert the problem to an equation using the percentage formula: Y/X = P%
X is 60, Y is 12, so the equation is 12/60 = P%
Do the math: 12/60 = 0.20
Important! The result will always be in decimal form, not percentage form. You need to multiply the result by 100 to get the percentage.
Converting 0.20 to a percent: 0.20 * 100 = 20%

Answer:
The area of this composite figure is 122.75 m².
Step-by-step explanation:
What I can go on ahead & do is split this figure into a 5 * 16 rectangle and a 9 by 9.5 triangle.
(5 * 16) + 1/2(9 * 9.5) {Multiply 5 by 16 first; go from left to right}
80 + 1/2(9 * 9.5) {Now multiply 9 by 9.5}
80 + 1/2(85.5) {Then multiply 85.5 by 1/2, which is the same thing as dividing by 2}
80 + 42.75 {Lastly, add the two values together}

A model of a house is 6 inch wide and 8 inches long. If the actual house is 20 yards long, how wide is the actual house?
A) 2.4 yd
B) 4.8 yd
C) 15 yd
D) 26 yd
Answers
We can create a ratio of length to width. The length of the model is 8, while the width is 6. This is a 4:3 ratio of length to width. We can input this into the actual length, 4(5):3(5) = 20:15. Therefore, the actual width is 15 yd

1112−412=?
The two fractions have like denominators so you can subtract the numerators.
Then:
11−412=712
This fraction cannot be reduced.
Therefore:
1112−412=712
Solution by Formulas
Apply the fractions formula for subtraction, to
1112−412
and solve
(11×12)−(4×12)12×12
=132−48144
=84144
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(84,144) = 12
84÷12144÷12=712
Therefore:
1112−412=712

5. Find the equation of a circle whose center is at (5, -8) and radius 8.
Answers
Answer:
[tex]x^{2} + y^{2} -10x -16y + 39[/tex]
Step-by-step explanation:-
The equation used to find the equation of circle is :-
[tex](x-a)^{2} + (y-b)^{2} = radius^{2}[/tex]
'a' means the x coordinate of the circle, 'b' means y coordinate of the circle.
In the question, it's given that the coordinates of the circle are (5, -8) and radius is 8cm.
So, 'a' will be 5 and 'b' will be -8
So,
[tex](x-5)^{2} + (y--8)^{2} = 8^{2}[/tex]
[tex](x-5)^{2} + (y+8)^{2} = 64[/tex]
[tex]x^{2} - 10x + 25 + y^{2} - 16y + 64[/tex]
[tex]x^{2} + y^{2} -10x -16y + 64 - 25[/tex]
= [tex]x^{2} + y^{2} -10x -16y + 39[/tex]
