Answers
Answer:
x=2, y=5
Step-by-step explanation:
the triangle that x is in is a right triangle (don't remember the theorem sorry)
use pythagorean theorem (a^2 + b^2 = c^2)
x is the hypotenuse(c)
1 squared plus /3 squared =c squared
1+3= c squared
4= c squared
c=2
x=2
find y using pythagorean theorem as well
/12 squared plus 2 squared = y squared
y is the hypotenuse
12+4=y squared
16= y squared
4=y
add one to account for that extra little piece
y=5
... I don't see z
Answer:
y= if it is the hypoteneuse for the whole triangle it √16 or 4, if it is the side of the smaller triangle it is 3
x=√4 which is 2
z= I don't think ther's a z

Which is true about quadrant equations
Answers
Answer: In algebra, a quadratic equation (from the Latin quadratus for " square ") is any equation having the form where x represents an unknown, and a, b, and c represent known numbers, with a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no term.
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Hey there !!!
the question is incomplete the full question is Which of the following statements is TRUE/CORRECT about Quadratic Equations? A quadratic equation is _____
with options
A) an expression with a single variable and degree 2
B) an equation with a single variable and degree 2
c) an equation with only degree to 2
D) an equation with single variable only
and the correct answer is B
because Quadratic Equation states that An equation with one variable and degree 2 is a Quadratic Equation. Only option b satisfies the two basic conditions of a quadratic equation i.e. one/single variable and degree 2. Hence b is the correct answer.

Rewrite this expression using the distributive property.
(3x2 + 4x-7)(x-2)
Answers
Answer:
D
Step-by-step explanation:
Each factor on the right has to be multiplied by the equation on the left and then you add them.
The expression (3x² + 4x - 7) ( x- 2) can be rewritten as 3x³- 2x²- 15x + 14.
To rewrite the expression (3x² + 4x - 7) ( x- 2) using the distributive property, we need to distribute each term in the first polynomial to each term in the alternate polynomial.
(3x² + 4x - 7) ( x- 2)
= 3x²( x- 2) + 4x( x- 2)- 7( x- 2)
Now, distribute each term
= 3x³- 6x²+ 4x²- 8x- 7x + 14
Combine like terms
= 3x³- 2x²- 15x + 14
Thus, using the distributive property, the expression (3x² + 4x - 7) ( x- 2) can be rewritten as 3x³- 2x²- 15x + 14.

So for this problem that would be:

2(-1)
Now that you have x, to find y you need to just simply plug the number that you got for x back into the original equation and solve. Like this-
y= -(-3)2-6(-3)-10
y= 6+18-10
y= 4
This means that your vertex is (-3, 4).
I’m not sure if the 2 next to the x is meant to be squared instead of just 2, so let me know if it was meant to be that and I’d be happy to redo it for you!

Answers
Answer:
[tex]x = 4[/tex] -- Marcus
[tex]y = 11[/tex] -- Raquel
Step-by-step explanation:
Given
[tex]x =Marcus[/tex]
[tex]y = Raquel[/tex]
[tex]x + y = 15[/tex] -- Both
[tex]y = 2x + 3[/tex] -- Raquel
Required
Determine x and y
Substitute 2x + 3 for y in [tex]x + y = 15[/tex]
[tex]x + 2x + 3 = 15[/tex]
[tex]3x + 3 = 15[/tex]
Collect Like Terms
[tex]3x = 15-3[/tex]
[tex]3x = 12[/tex]
Divide both sides by 3
[tex]x = 4[/tex]
Substitute 4 for x in
[tex]y = 2x + 3[/tex]
[tex]y = 2 * 4 + 3[/tex]
[tex]y = 8 + 3[/tex]
[tex]y = 11[/tex]

What is inequality?Mathematical equations with inequalities on both sides are known as inequalities. In an inequality, we compare these two values as opposed to equations. Somewhere between, the equal sign is changed to a less than (or less than or similar to), bigger than (or greater or equal to), or just not equal to sign.

The side which has got a larger angle has the largest side.
The side c is greater than a and side b is also greater than a.

Step-by-step explanation:
30:12 is the original ratio. So if you divide both sides by the numbers' GCF of 6 you'll get a simplified ratio of 5:2. Then multiply both sides by 4 to keep the ratio constant, then you'd get 20:8.

2. For something to be an odd function, it has to have symmetry to the origin, not the x-axis. This means that if it has a point like (a, b), it also has the point (-a, -b). For example, y = x is an odd function because it does this.
