If f(x) = -x^2 +5z and g (x) = 2x-4 find
Answer:
1) x=√−y+5z or x=−√−y+5z
2) g=2x-4/x
Step-by-step explanation:
explanation for first problem:
Let's solve for x.
y=−x^2+5z
Step 1: Flip the equation.
−x^2+5z=y
Step 2: Add -5z to both sides.
−x^2+5z+−5z=y+−5z
−x^2=y−5z
Step 3: Divide both sides by -1.
−x^2
−1
=
y−5z
−1
x2=−y+5z
Step 4: Take square root.
x=√−y+5z or x=−√−y+5z
explanation for problem 2:
Let's solve for g.
gx=2x−4
Step 1: Divide both sides by x.
gx/x = 2x-4/x
g=2x-4/x

-2x - 3(2x - 4) = 4(x – 6)
3(x - 2) = x + 2x - 5
Answer:
x = 3
No Solution
Step-by-step explanation:
-2x - 3(2x - 4) = 4(x – 6) this means x would equal 3 because if you isolate the variable by dividing each side by factors that don't contain the variable.
3(x - 2) = x + 2x - 5 would have no solution because there are no values of x that make the equation true.

Step-by-step explanation:
Agustín y Bárbara salen al mismo tiempo y del mismo lugar, por el mismo camino. Agustín camina a 5km/h y Bárbara a 3km/h. Luego de recorrer 7km, Agustín emprende el regreso, ¿a qué distancia de la partida se encuentra con Bárbara? Si en el momento del encuentro también Bárbara emprende el regreso, ¿cuántos minutos después que Agustín llega Bárbara al punto de partida?
Answer:
Ok, primero Agustín camina a 5km/h.
Cuando el recorre 7km, el regresa.
El tiempo en el que sucede esto es a:
7km/5km/h = 1.4 h
La ecuación para Agustín es:
A(t) = 5km/h*t para 0h ≤ t ≤ 1.4h (ida)
A(t) = 7km - 5km/h*(t - 1.4h) para 1.4h ≤ t. (vuelta)
Hacemos lo mismo para Barbara:
7km/3km/h = 2.5h
La ecuación para ella es:
B(t) = 3km/h*t para 0h ≤ t ≤ 2.5h (ida)
B(t) = 7km - 3km/h*(t - 2.5h) para 2.5h ≤ t. (vuelta)
a) ¿a qué distancia de la partida se encuentra con Bárbara?
Tenemos que ver cuando A(t) = B(t).
Para ello comparamos la vuelta de Agustín con la ida de Barbara.
7km - 5km/h*(t - 1.4h) = 3km/h*t
7km - 5km/h*T + 7km = 3km/h*T
14km = 8km/h*t
14/8 h = 1.75h = t.
Entonces la posición en la que se encuentran es:
B(1.75h) = 3km/h*1.75h = 5.25km
Ellos se encuentran a 5.25 kilómetros de el punto de partida.
b) Si en el momento del encuentro también Bárbara emprende el regreso
(Es decir, en este momento Barbara comienza a regresar).
Entonces ella para regresar al punto de inicio tiene que recorrer 5.25km con una velocidad de 3km/h.
Tb = 5.25km/3km/h = 1.75h
Barbara tarda 1.75 horas en regresar.
Agustín también tiene que recorrer 5.25 km para regresar, pero su velocidad es 5km/h.
Ta = 5.25km/5km/h = 1.05h.
La diferencia entre los tiempos es:
Tb - Ta =1.75h - 1.05h = 0.7h
Entonces Barbara llega al punto de partida 0.7 horas después que Agustín.
Pero queremos esto en minutos.
1 hora = 60 minutos.
0.7 horas = 0.7*(60 min) = 42min
Barbara llega 42 minutos después que Agustín.

what is the opposite of −(−6.3)
Answer:
the reicprocal is -1/6.3
Step-by-step explanation:
Mara found the length of time of an investment. The principal of the investment was $4,300, the interest rate was 6.2 percent, and the interest was $2,666. Mara made an error in her work.
I = p r t. 2666 = (4300) (0.062) t. 2666 = (266.6) t. StartFraction 266.6 over 2666 EndFraction = t. 0.1 = t.
well, 6.2% of 4,300 can't be over half. she has made a calculation error, and the real answer is (this is where the mistake was made) 4,300 * 0.062 (not 6.2, because percents are always divided by 100 to make them into a usable number), which is equal to $266.60.
Triangle XYZ is a right triangle with the right angle at vertex Y.
Angle X must be
.
Angle Z must be
.
The sum of angles X and Z must be
90°.
The sum of angles X and Z is 90°.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Triangle XYZ.
∠Y = 90°
Now,
The sum of the three angles must be 180°.
So,
∠X + ∠Y + ∠Z = 180
∠X + ∠Z = 180 - 90
∠X + ∠Z = 90
Thus,
∠X + ∠Z = 90

The slope intercept form of the given line equation is y = x/2 - 1.
The given equation of a line is x-2y=2.
The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
Here, the equation can be written in slope intercept form as
x-2y = 2
2y = x-2
y = x/2 - 2/2
y = x/2 - 1
Therefore, the slope intercept form of the given line equation is y = x/2 - 1.

150+25x=55x what is the answer?
Answer:
x = 5
Step-by-step explanation:
150+25x= 55x
-25x -25x
150= 30x
150/30 = 30x/30
x = 5
Hope this helps!
Answer: x =5
Steps: 150 + 25x = 55x
Subtract 150 from both sides: 150 + 25x - 150 = 55x - 150
Simplify: 25x = 55x - 150
Subtract 55x from both sides: 25x - 55x = 55x - 150 - 55x
Simplify: -30x = -150
Divide both sides by -30: -30x ÷ -30 = -150 ÷ -30
Simplify: x = 5

What is the vertex of this parabola?
y-5 = x^2?
====================================================
Work Shown:
y-5 = x^2
y = x^2 + 5 ... add 5 to both sides
y = 1x^2 + 5
y = 1(x-0)^2 + 5 ... x replaced with (x-0)
The equation is now in the form y = a(x-h)^2 + k
We have a = 1, h = 0, k = 5.
The vertex is (h,k) = (0,5)
The value of 'a' determines how vertically stretched or compressed the parabola is. Also, if a > 0, then the parabola opens upward; or if a < 0, then the parabola opens downward.
