Answer:
i think it is y = -4/5x + 4
Step-by-step explanation:
4x + 5y = 20
Subtract 4x on both sides
5y = -4x + 20
Divide 5 on both sides
y = -4/5x + 4

Answer:
C = 94
Step-by-step explanation:
Say the centre point is Y, then the triangle BCY is an isosceles, therefore angle BCY = angle CBY
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
answer is 94 degrees
Answer:
94

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?
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.

Find the rate of change of the linear function
shown in the graph. Then find the initial value.
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".

Evaluate h(8q2 - 2g) for h(x) = 7x+ 4q
Answer:
56q2 - 10q
Step-by-step explanation:
1. the function is given h(x) = 7x + 4q
2. we should put (8q2 - 2q) instead of x
3. we should write when x = 8q2 - 2q
then it will be h(8q2 - 2q)= 7(8q2 - 2q) + 4q
4. then we should multiply the elements in the bracket with 7 then it will be 56q2 - 14q + 4q
5. then we should substract -14q + 4q then it will be -10
