Step-by-step explanation:
-4x+y=3 and 2x-y=12. which of the options represents the resulting equation after an equivalent expression for yw is substituted into the second equation. Odessyware!
Answer:
2x - (3 + 4x) = 12
x = -7.5
y = -27
Step-by-step explanation:
-4x + y = 3 (1)
2x - y = 12 (2)
From (1)
y = 3 + 4x
Substitute y = 3 + 4x into (2)
2x - y = 12 (2)
2x - (3 + 4x) = 12
2x - 3 - 4x = 12
2x - 4x = 12 + 3
-2x = 15
x = 15/-2
x = -7.5
Substitute x = -7.5 into (2)
2x - y = 12 (2)
2(-7.5) - y = 12
-15 - y = 12
-y = 12 + 15
- y = 27
y = -27

A triangle has side lengths of ( 4h + 2k) centimeters, (9h + 4m) centimeters, and (2m - k) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
P = (13h+k+6m) cm
Step-by-step explanation:
Given that,
The side lengths of a triangle are :
(4h + 2k) cm, (9h + 4m) cm, and (2m - k) cm
We need to find the perimeter of the triangle.
We know that,
Perimeter = sum of all sides
So,
P = (4h + 2k)+(9h + 4m)+(2m - k)
= (4h+9h)+(2k-k)+(4m+2m)
= 13h+k+6m
Hence, the perimeter of the triangle is (13h+k+6m) cm.
Mai is playing a game with a class of second graders. Mai knows she is exactly 120 inches from the mirror on the floor. She has students stand so that she can just see the top of their heads and then guesses their heights. The students are amazed!
Diagram of 2 stick figures.
How is Mai so accurate?
Mia is able to find the height of the students so accurately using the tangent property of trigonometry.
What is Tangent (Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
The base is the adjacent smaller side of the angle θ.
As it can be seen that there are two right triangles, therefore, using the tangent property of the trigonometry, Mia is able to find the height of the students so accurately.

A number squared is just the number times itself.
[tex]n(n)=n^2[/tex]
Answer:
A number squared is a number to the power of 2 or the number times itself.
Step-by-step explanation:
Lets say you have a 4 to the 2nd that would mean that the 4 is multiplied by 4. Dont get the exponent confused as the number to multiply it as. Look at [tex]9^{2}[/tex] for example, you would multiply the number 9 2 times not 9 times 2 so it would be 9x9.

Maryann works six and one-quarter hours on Saturday at $9 an hour. What are her earnings on Saturday?
Answer:
56.25
Step-by-step explanation:
6*9=54+2.25= 56.25
Answer:
$56.25
Step-by-step explanation:
So first off we have 6 1/4 hours being worked at the rate of 9 dollars and hour. 6 hours multiplied by 9 dollars will give you 54 dollars. After that all we need to do is get a quarter of 9 dollars, which is $2.25 adding this to our original number of 54, we have $56.25. Hope this helps!

X = 60
Y = 50
Step-by-step explanation:
The total degrees of a triangle is 180 degrees. For the middle triangle, 50+70=120 so 180-120=60.
On the far right, Y=50 because you take 50 degrees from the middle triangle, and insert it there.

Which of the following are valid names for the triangle below? Check all that
apply.
А
R
O A. AJKE
B. AEJR
O C. AKE
O D. AKEJ
ОЕ. ДЈЕ
OF AJAOE
Answer:
A and D!
A-JKE
D-KEJ
Step-by-step explanation:
JKE and KEJ line up and are in the correct position and order to form the triangle listed by themselves. The other ones will not form even the same shape!
The reason why the other ones aren't elgible: EJR, KE and JE just form a line, and JAOE forms an uneven trapezoidal shape (forgot what it was called)
So that would leave JKE and KEJ, which are the only ones that line up.
The correct options are ΔJKE and ΔKEJ.
A and D are correct.
What is a Triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices.
