Select the quadratic equation that has no real solutions. 25x-10x+4=0
Answer:
Step-by-step explanation:
Were there not several equations from which to choose?
The coefficients of 25x^2 - 10x + 4 are {25, -10, 4}. The discriminant is thus b^2 - 4ac, or (-10)^2 - 4(25)(4), or 100 - 400, or -300. Because the discriminant is negative, the quadratic has no real solutions.
The quadratic equation with no real solution is 25x²-10x+4 = 0
What is a quadratic equation?The meaning of quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.
Given that, which of the equations have no real solution,
Considering the quadratic equation 25x²-10x+4 = 0
D = [tex]\sqrt{b^{2} -4ac}[/tex]
We know, when √D > 0, real roots
√D = 0, equal roots
√D < 0, imaginary roots
[tex]\sqrt{b^{2} -4ac}[/tex] =
[tex]\sqrt{10^{2} -400} \\\sqrt{-300}[/tex]
Since, the discriminant is less than 0, therefore, its roots are imaginary.
Hence, The quadratic equation with no real solution is 25x²-10x+4 = 0

Actually Welcome to the Concept of the exponents and indices.
here, we should remember one thing that,
3 ^3 = 27 and 1/3^x = 3^-x
so we get as,
(3^-3)^4-x = (3^3)^2x-1
==> 3^-12+3x = 3^6x-3
since the base is same that is 3 , we equate their powers.
-12x+3=6x-3
==> 3+3 = 6x+12x
==> 6 = 18x
hence ===> x = 6/18 = 1/3
hence, x = 1/3
Classify the number -3 into as many categories as it belongs: Natural number, whole number, integer, or rational number.
-12x + 2 y = 8
-6x + y = -3

find the missing side each triangle.round your answers to the nearest tenth if necessary
Answer:
x = 6
Step-by-step explanation:
The triangle is a right triangle, as denoted by the red square at the bottom, we can use the Pythagorean Theorem to figure out the second side (since we are given the other side and the hypotenuse).
a² + b² = c²
(8)² + b² = (10)²
64 + b² = 100
b² = 100 - 64 = 36
b = ±[tex]\sqrt{36}[/tex]
b = ± 6
But we know that distance is always positive, so
b = 6
I have used b in place of x if you are confused about the variable usage.

How many solutions does the equation 2(x+1) = 2x+1 have?
Answer:
No SolutionsExplanation:
2(x + 1) = 2x + 1
Simplify both sides of the equation2(x + 1) = 2x + 1
(2)(x) + (2)(1) = 2x + 1 [Distribute]
2x + 2 = 2x + 1Subtract 2x from both sides2x + 2 − 2x = 2x + 1 − 2x
2 = 1
Subtract 2 from both sides2 − 2 = 1 − 2
0 = −1

-4x + 16 = y
2x - 32 = 2y
Step 2: Solve for x
Substitution
Substitute in y: 2x - 32 = 2(-4x + 16)Distribute 2: 2x - 32 = -8x + 32[Addition Property of Equality] Add 8x on both sides: 10x - 32 = 32[Addition Property of Equality] Add 32 on both sides: 10x = 64[Division Property of Equality] Divide 10 on both sides: x = 32/5Step 3: Solve for y
Define original equation: -4x + 16 = ySubstitute in x: -4(32/5) + 16 = yMultiply: -128/5 + 16 = yAdd: -48/5 = yRewrite/Rearrange: y = -48/5What is the polynomial in standard form?
What is the solution to the system of equations y = -1/2 x + 1 and y = 2x + 6?
Answer:
Since by the 2nd equation, we know that y is the same as 6-x, we can substitute that for y in the first equation:
y = 2x + 3 -> 6 - x = 2x + 3 -> 6 = 3x + 3 -> 3 = 3x -< x = 1 and by either of the two equations, that derives y = 5
Step-by-step explanation:
Answer:
ok you can use subsitution for this one
since y=2x+6
subsitute 2x+6 for y
3x-(2x+6)=6
3x-2x-6=6
add like terms
x-6=6
add 6 to both sides
x=12
subsitute
y=2x+6
y=2(12)+6
y=24+6
y=30
x=12
y=30
