what triangle has one right angle and two congruent sides?
Answer:
The angles in an equilateral triangle are always 60°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent. A triangle without any congruent sides or angles is called a scalene triangle.

A pair of parallel lines are translated. Which of these could be the result?
Answer:
c
Step-by-step explanation:
A translation is a transformation that moves every point in a figure in the same direction by the same amount. The correct option is C.
What is translation?A translation is a transformation that moves every point in a figure in the same direction by the same amount. It is also a sort of transformation in which each point in a figure is moved the same distance in the same direction resulting in the same figure again.
Given that a pair of parallel lines are translated, after the translation, the pair of the line will be still parallel. Therefore, the graph with parallel lines is the correct option.

A. 24
B. 22
C. 10
D. 9
Answer:
B
Step-by-step explanation:
Since x is 2 wherever you see x put 2
solve x3 + x7+ 2
=(2)3 + (2)7 + 2
= you do the number outside the bracket multiplied by the number inside the bracket
like this
=(2 × 3) + (2 × 7) + 2
= 6+ 14 + 2

Evaluate functions from their graph g(-9)
Please help my teacher doesn’t teach us anything and just gives us khan academy assignments and I’m really stressing out from this assignment
At the coordinate of -9, the value of the function g(-9) will be 1.
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that in the graph the function is varies with the value of the coordinates, at the value of -9 the solution for the function g(-9) will be equal to 1
g(-9) = 1
Hence, the value of the function will be 1.

what is 9 ounces equal to in pounds? please answer in fractions:)
Answer:
9/16
Step-by-step explanation:
First, note that 10000 multiplied by .5625 will get rid of the decimal point. Therefore, make a fraction where the numerator is .5625 times 10000 and denominator is 10000 like this:
.5625 x 10000
10000
Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:
5625 /10000
The greatest common factor of 5625 and 10000 is 625, which means you can divide the numerator and denominator by 625 and keep the same value:
5625 ÷ 625 /10000 ÷ 625
And when calculating the numerator and denominator in our fraction above, we get .5625 as a fraction in the simplest form possible:
.5625 =

Ms. Morales showed her geometry student the figure below and told them that DE BC. She asked them to use this information to prove that DE divides AB and AC proportionally. Hannah used the midpoint formula to show that AD=DB and AE=EC. Jaden uses the slope formula to prove that DE and BC have equal slopes. Omar used the distance formula to show that AD/DB=AE/EC. Which student or students used a formula that will help them prove the relationship?
Answer: Hannah and Omar Only
Step-by-step explanation:
Self explanatory
Hannah and Omar Only used a formula that will help them prove the relationship.
ProportionallyA line drawn parallel to one side of a Δ divides the other two sides in the same ratio.
Given
To prove that DE divides AB and AC proportionally.
Construction: If DE is not parallel to BC, draw DF meeting AC at F.
Proof: In ΔABC, let DF || BC
[tex]\rm \dfrac{AD}{DB}=\dfrac{AC}{FC}\\\\[/tex]
A line drawn parallel to one side of a Δ divides the other two sides in the same ratio.
[tex]\rm \dfrac{AD}{DB}=\dfrac{AE}{EC}\\\\[/tex]
From (i) and (ii), we get
[tex]\rm \dfrac{AD}{DB}=\dfrac{AC}{FC}=\rm \dfrac{AE}{EC}\\\\[/tex]
Hence, Hannah and Omar Only used a formula that will help them prove the relationship.
