x^2+6x-16=0
quadratic equation
Answers
Answer:
x = - 8, x = 2 are the solutions
Step-by-step explanation:
Given
x² + 6x - 16 = 0
Consider the factors of the constant term (- 16) which sum to give the coefficient of the x- term (+ 6)
The factors are + 8 and - 2 , since
8 × - 2 = - 16 and 8 - 2 = + 6 , thus
(x + 8)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x - 2 = 0 ⇒ x = 2

Find the rate of change of the linear function
shown in the graph. Then find the initial value.
Answers
Answer:
4 ; Initial value is (- 1)
Step-by-step explanation:
The rate of change of a linear function is slope of the line.
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
(0, - 1)
(1, 3)
m = [tex]\frac{-1-3}{0-1}[/tex] = 4
Initial value is - 1
y = 4x - 1
The equation of the graph is y = 4x - 1 with a rate of change of 4. The initial value of the function is y = -1.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
As per the given graph,
The rate of change or slope of a function is the ratio of the difference of y's and x's coordinates.
Therefore, let's consider two points (0,-1) and (1,3)
Slope = (3 - (-1))/(1 - 0)
Slope = 4
The y-intercept is -1 so the equation will be y = 4x - 1.
The initial value of function at x = 0 is y = 4(0) - 1 = -1.
Hence "The equation of the graph is y = 4x - 1 with a rate of change of 4. The initial value of the function is y = -1".

Step-by-step explanation:
Tenemos un rectángulo cuya área es (15n + 9nx) cm 2 y su base mide (3n) cm. Existe también un cuadrado con la misma altura del rectángulo, tal que si al área del cuadrado se le disminuye (9x 2 ) cm 2 , ésta medirá 1825 cm 2 . ¿Cuánto mide el área original del cuadrado?
Answers
Answer:
El área original del cuadrado es 34225 cm²
Step-by-step explanation:
Los parámetros dados son;
El área del rectángulo = (15·n + 9·n·x) cm²
La longitud de la base del rectángulo = (3·n) cm
La altura del cuadrado = La altura del rectángulo
El área original del cuadrado - 9·x² cm² = 1825 cm²
La altura del rectángulo = (El área del rectángulo) / (La longitud de la base del rectángulo)
∴ La altura del rectángulo = (15·n + 9·n·x) / (3·n) = 5 + 3·x
La altura del rectángulo = 5 + 3 · x = La altura del cuadrado
El área del cuadrado = Lado × Lado = Altura × Altura = (5 + 3·x) × (5 + 3·x)
∴ El área del cuadrado = (5 + 3·x) × (5 + 3·x) = 9·x² + 30·x + 25
Del área original del cuadrado - 9·x² cm² = 1825 cm², tenemos;
9·x² + 30·x + 25 - 9·x² = 1825
30·x + 25 = 1825
30·x = 1825 - 25 = 1800
x = 1800/30 = 60
x = 60
El área original del cuadrado - 9·x² cm² = 1825 cm²
El área original del cuadrado = 1825 cm² + 9·x² cm² = 1825 cm² + 9 × 60² cm² = 34225 cm²
El área original del cuadrado también se puede encontrar de la siguiente manera;
El área original del cuadrado = (5 + 3 × 60) × (5 + 3 × 60) = 34225 cm²
El área original del cuadrado = 34225 cm².

So the base points of that triangle are both 47, to find the angle of BYC, you just do:
180 - 47 - 47 = 86
and then since x is on a line with 86, and angles on a straight line add up to 180:
180 - 86 = 94
