Answer:
1) x = 5
2) y = 5·√2
Step-by-step explanation:
1) The given parameter of the right triangle are;
The legs of the right triangle = 'x', and 5
One interior angle of the right triangle = 45°
Therefore, buy the interior angle summation property of a right triangle, we have;
The measure of the other angle, θ = 180° - 90° - 45° = 45°
From which we have;
A right triangle with an interior angle of 45° is an isosceles triangle with both legs equal
∴ The length of the other leg, x = 5
x = 5
2) By Pythagoras's theorem, we have that the square of the length of the hypotenuse, 'y', is given as follows;
y² = x² + 5²
∴ y² = 5² + 5²
y = √(5² + 5²) = √(25 + 25) = √50 = √(25 ×2) = 5·√2
y = 5·√2 in the simplest radical form.

Reasoning Solve the system of linear equations using substitution. Use pencil and paper. Which expression would be easier to substitute into the other equation, in order to solve this problem? Explain your reasoning. x = 4y - 2 x + 4y =7
Answer:
x = 5 /2 , y = 9 / 8
Step-by-step explanation:
x = 4y - 2 ....... (i)
x + 4y =7 ....... (ii)
Substituting eqn (i) into eqn (ii);
(4y - 2 ) + 4y = 7
4y - 2 + 4y = 7
8y = 7 + 2 = 9
y = 9 / 8
substitute y = 9 / 8 in eqn (i)
x = 4 (9 / 8) - 2
x = 9 / 2 - 2
x = (9 - 4 ) / 2
x = 5 / 2

how do i graph y=-x+3
Answer:
y=-x+3 follows the same equation as y=mx+b
3 is b, and b is the y-intercept. The y intercept is where the line crosses on the y axis, and -x is is m, which is the slope. However since its a variable, its point is on the same number as positive three on the y axis, so then its 3 on the x axis.

Answer:
A. x = 6.08, x = -0.58
Step-by-step explanation:
[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{x^2-10x+24}=\frac{-3}{x-6}[/tex]1. Factor the denominator.
[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]2. Multiply the leftmost fraction by (x-6)/(x-6) to get common denominators.
[tex]\displaystyle \Big ( \frac{x-6}{x-6} \Big ) \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]3. Simplify.
[tex]\displaystyle \frac{2x^2-12x}{(x-4)(x-6)}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]4. Combine like terms.
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6}[/tex]5. Multiply the right side of the equation by (x-4)/(x-4).
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6} \Big ( \frac{x-4}{x-4} \Big )[/tex]6. Simplify.
[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3x+12}{(x-6)(x-4)}[/tex]7. "Cancel" out the denominators because they are equivalent.
[tex]2x^2-14x+5=-3x+12[/tex]8. Set the equation equal to 0.
[tex]2x^2-11x-7=0[/tex]Quadratic formula:
[tex]\displaystyle x = \frac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]9. Factor using the quadratic formula.
[tex]\displaystyle x = \frac{-(-11)\pm \sqrt{(-11)^2-4(2)(-7)} }{2(2)}[/tex]10. Multiply and simplify.
[tex]\displaystyle x = \frac{11 \pm \sqrt{177} }{4}[/tex]11. Plug this into your calculator and solve for x.
[tex]x=6.07603367 \approx 6.08[/tex] [tex]x=-0.57603367 \approx -0.58[/tex]The correct answer is A. x = 6.08, x = -0.58.

Zachary is standing in a stadium and has the option of running up a staircase or down a staircase for exercise.
The function f(x)= 1/25(∣4x∣+2x) will determine how many calories Zachary will burn if he runs up x steps. Use a negative value for x if he runs down the stairs. What does the domain represent in this function?
Answer:
R(All real numbers)
Step-by-step explanation:
We are given that the calories burn in x steps of running is given by
[tex]f(x)=\frac{1}{25}(|4x|+2x)[/tex]
We have to find the domain of this function.
We know that
|x|=[tex]x, x\geq 0[/tex]
-x, x<0
Therefore, the function
[tex]f(x)=\frac{1}{25}(4x+2x) ,x\geq 0[/tex]
[tex]\frac{1}{25}(-4x+2x) ,x<0[/tex]
[tex]f(x)=\frac{1}{25}(6x), x\geq 0[/tex]
[tex]\frac{1}{25}(-2x), x<0[/tex]
The function is defined for all values of x.
Therefore, the domain of f(x)=All real numbers (R)
