Does an isosceles triangle have three congruent sides?
Answer:
It can... an isosceles triangle by definition has two or more congruent sides. An equilateral triangle will always have three congruent sides. An equilateral triangle will always be an isosceles triangle but an isosceles triangle will not always be an equilateral triangle. I hope this helps!

-16x - 7 = 8x + 13
what are y’all opinions on this
Answer:
-20/24 or -5/6
Step-by-step explanation:
Move all the x's to one side of the equal sign and the numbers to the other side: -16x - 8x = 13 + 7Next, simplify: -24x = 20Finally divide both sides by -24: x = -20/24 or -5/6Hope this helps!
Answer:
x=5/6
Step-by-step explanation:
-16x - 7 = 8x + 13
-8 -8
-24x + -7 = 13 (Change addition to subtraction and add the opposite)
7 7
-24x = 20
24 24
x = 0.8333333

Answer:
x=13
z=79
Step-by-step explanation:
The angles given are supplementary. This means that when added their sum will be 180. So add the 2 expressions together and set them equal to 180.
This looks like, (8x-25)+(6x+23) = 180. Then, combine like terms in the equation to get the next step, 14x-2 = 180. Next, add 2 to both sides. Finally, divide both sides by 14.Therefore, x=13Then, you have to find z. The angle z is congruent to the angle with the measure (8x-25). This is because they are vertical angles, and therefore congruent. So, plug 13 into the expression, 8(13)-25=79 degrees. Since that angle equals 79, z must also equal 79.

Solve the quadratic equation x2+3x−10=0 by completing the square.
What is the solution, or what are the solutions, to the equation?
Enter your answer as the correct value or values. If there is more than one solution, use a comma between the values, like this: 42, 53
A quadratic equation is in the form of ax²+bx+c. The solution of the given quadratic equation is 2 and -5.
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
Given the quadratic equation x²+3x-10=0, the solution to this equation can be done as shown below.
x² + 3x - 10 = 0
Keep x terms on the left and move the constant to the right side by adding it on both sides,
x² + 3x = 10
Take half of the x term and square it,
x = (3/2)² = 9/4
Then add the result to both sides
x² + 3x + (9/4) = 10 + (9/4)
Combine terms on the right,
(x + 3/2)² = 49/4
Taking under root,
x + 3/2 = ± 7/2
Now,
x = 7/2 - 3/2 = 2
x = -7/2 - 3/2 = -5
Hence, the solution of the given quadratic equation is 2 and -5.

Step-by-step explanation:
If light travels about 3 x 10^5 kilometers per second, about how many kilometers does it travel in one day? Write the answer in scientific notation.
Since there are 86400 seconds / day
& light travels at 3 x 10⁵ kilometers / second
Then kilometers the light travels in a day
= (86400 seconds / day) × (light travels at 3 x 10⁵ kilometers / second)
= 2.59 × 10¹⁰ kilometers/day
Note:
We know that we have to multiply because the unit 'seconds per day' has the seconds in the numerator, while the unit 'kilometer per second' has the seconds in the denominator, so to cancel we would have to multiply. This gives us the unit we are looking for 'kilometeres per day'.

Step-by-step explanation:
One of the points is (1,-1), and the slope is 3.
The point slope equation is [tex]y-y_{1} = m(x-x_{1} )[/tex] where m is the slope.
It would then be y+1=3(x-1), which is B)

A high school teacher teaches three classes per day. Her first class has double the number of students as her second class, while her third class has 13 more students than her second class. In total, she teaches 53 students. The equation 2x + x + (x +13) = 53 represents this scenario, where x is the number of students
in her second class.
How many students are in her second class?
Answer: 10
Step-by-step explanation: first subtract 13 from 53 which gives you 40 then divide 40 by 4 which gives you 10 but because your first class is double more than your second class it has 20 students and your second class has 10 students and because you have to add that 13 back in your third class has 23 students
