-2x^2+5x-4=0 , find the discriminant
Answer:
The discriminant is -7
Step-by-step explanation:
The discriminant of a quadratic function/equation(ax^2+bx+c = 0) is calculated as:
[tex]b^2 -4ac[/tex]
Here
b is the co-efficient of x
a is the co-efficient of x^2
and c is the constant
Given equation is:
[tex]-2x^2+5x-4=0[/tex]
Here
a = -2
b = 5
c = -4
Putting the values in the formula for discriminant
[tex]= b^2 - 4ac\\= (5)^2 - 4(-2)(-4)\\= 25 - 32\\=-7[/tex]
As the discriminant is negative, the equation has no real solution.
Hence,
The discriminant is -7
full process to find HCF of x^3 -1 and x^4+ x^2 + 1
Answer:
Step-by-step explanation:
Factor of x^3-1= (x-1)(X^2+X+1)
Apply the formula of a^3-b^3=(a-b)(a^2+b^2+1)
X^4+x^2+1=(x^2+X+1)(x^2-x+1)
H.c.f is (x^2+X+1)
The rule R x-axis ∘ T⟨–5, 3⟩ is applied to the point (–3, –2). Where is the image in the coordinate system?
Given:
Rule of transformation is rule R x-axis ∘ T⟨–5, 3⟩.
The point is (-3,-2).
To find:
The image of given point after the transformation.
Solution:
Consider the given point be P(-3,-2).
Rule of transformation is rule R x-axis ∘ T⟨–5, 3⟩. If means first we have apply translation T⟨–5, 3⟩ after that we have to apply reflection R x-axis.
If a figure translated by T⟨–5, 3⟩, then
[tex](x,y)\to (x-5,y+3)[/tex]
[tex]P(-3,-2)\to P'(-3-5,-2+3)[/tex]
[tex]P(-3,-2)\to P'(-8,1)[/tex]
If a figure reflected by R x-axis, then
[tex](x,y)\to (x,-y)[/tex]
[tex]P'(-8,1)\to P''(-8,-1)[/tex]
Therefore, the image of given point after transformation is (-8,-1).

What is an equation of the line that passes through the point (-2,-3) and is parallel to the line 5x+2y=14
Answer: y=-5/2x-8
Step-by-step explanation:
The equation of the line that passes through the point (-2,-3) and is parallel to the line 5x+2y=1 is
y = (-5/2)x - 8
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
We have,
An equation of the line that passes through the point (-2,-3) and is parallel to the line 5x+2y=14.
The equation of a line can be written as:
y = mx + c _____(1)
The line 5x + 2y = 14 can be written in the form y = mx + c.
5x + 2y = 14
2y = -5x + 14
y = -5/2x + 7
m = -5/2 ____(2)
The equation of the line passes through the point (-2, -3) so,
From (1) and (2) we get,
y = mx + c
-3 = -5/2 x -2 + c
-3 = 5 + c
c = -3 - 5
c = -8 ____(3)
Now,
From (1) , (2), and (3) we get,
The equation of the line is
y = (-5/2)x - 8
Thus,
The equation of the line that passes through the point (-2,-3) and is parallel to the line 5x+2y=1 is
y = (-5/2)x - 8

For those who are good with equations....(unlike me when it comes to this)
Answer:
a = 5
Step-by-step explanation:
When the coefficients of the variables are equal with different constants, then you will get an equation which is never true.
For this particular equation, when a on the right side has a coefficient of 5, you will get the equation: 4(a - 2) + a = 5a - 4.
When you distribute the factors in the parenthesis and add the like terms of a together, 4(a - 2) + a will become 5a - 8. This is because 4(a - 2) + a = 4(a) + 4(-2) + a = 4a - 8 + a = 5a - 8.
Now when you simplify 5a - 8 = 5a - 4 by subtracting 5a from both sides, you will get an equation with unlike constants. For instance 1 = 0.
Now:
5a - 8 = 5a - 4
-5a -5a
-8 = -4
This is never true, so therefore, there is no solution.

It is 5

Give evidence or explain your reasoning for your answer to example #4:
Answer:
I think it displays Newton's 3rd law.
Step-by-step explanation:
Newton's third law says: Every action has a reaction that is equal in force and opposite in direction.
the air from balloon exerts force opposite to the air's direction in the balloon, and the fore is equal, that's why the balloon moves upwards.

Imagine someone makes $30,000 a year and receives two paychecks per month. The employer withholds 13.9% of that in federal income tax. What is the amount of each paycheck after federal income tax has been taken out?
Answer:
Step-by-step explanation:
30,000/12= 2500
2500/2 checks per month= 1250 per check
1250*13.9%=173.75 per check in federal taxes
1250-173.75= $1076.25 per check after federal tax
The amount of each paycheck after federal income tax has been taken out is $1,076.25.
Calculation of the amount:The per month payment be like
[tex]= 30,000 \div 12[/tex]
= 2,500
Since there are two paycheck for each one it should be
[tex]= 2,500 \div 12[/tex]
= 1,250
Now there is 13.9% of federal income tax
So,
= 13.9% of 1,250
= 173,.75
Now the amount should be
= $1,250 - $173.75
= $1076.25
Hence, The amount of each paycheck after federal income tax has been taken out is $1,076.25.

what does t=
Answer:
t = [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
10t - 19 = 7t - 14
Subtract 7t from both sides;
3t - 19 = -14
Add 19 to both sides;
3t = 5
Divide both sides by 3;
