Answer:
DB!
Step-by-step explanation:
Because if you multiply them out, they both equal 6k-30.
-6(5-k)=-30+6k, which is equal to 6k-30.
Hope I helped!
because you can use the distributive property with
-6(5-k)
-6×5= -30
-6×-1k= 6k
so that equals 6k-30

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.

Mike took a taxi from his home to the airport. The taxi driver charged an initial
fee of $6 plus $3 per mile. The total fare was $24, not including the tip. How many
miles did mike travel by taxi on this ride?
A. 2
B. 6
C. 8
D.10
Answer:
B. 6
Step-by-step explanation:
SInce the total amount paid by Mike was $24, you subtract the initial amount he paid ($6) which leaves you with $18. Since the taxi driver charges $3 per mile you divide $18 by $3 to get 6 so that means Mike travel 6 miles.

in the interval 0° ≤ x ≤360°, find the values of x for which tan x =1.3562 Give your answers to the nearest degree
Answer:
The answers are 54 degrees and 234 degrees
Step-by-step explanation:
mathematically we have the tan positive on only two axes
these are the first (0-90) degrees and the 3rd quadrant (180-270)
We start by find the arc tan of the angle value
Thus;
x = arc tan (1.3562)
x = 54 degrees
On the third quadrant, we have it that;
180 + 54 = 234 degrees

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

How many solutions are shown by the graph of the quadratic function? A zero B one C two D three
A solution to a quadratic is the same as the root or x intercept (when talking about real numbers). The graph shows that we have exactly one x intercept, which is where the parabola touches the x axis. So we have one root.

Algebra 1 need help (Solving exponents equations)
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
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

The diameter of a circle has endpoints of (2, 5) and (-4, 13). What is the correct equation of this circle? Pls explain and I will mark brainliest!
Answer:
Option 4Step-by-step explanation:
Midpoint of the diameter is the center.
Use midpoint formula to determine the coordinates:
x = (2 - 4)/2 = -1y = (5 + 13)/2 = 9Find the radius using the midpoint and one of the endpoints and the distance formula:
r = [tex]\sqrt{(-1 - 2)^2 + (9 - 5)^2} = \sqrt{9+16} = \sqrt{25} = 5[/tex]Use the equation of the circle:
(x - (-1))² + (y - 9)² = 5²(x + 1)² + (y - 9)² = 25Correct choice is 4
