Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(2,−4)
Equation Form: x= 2, y = −4
Step-by-step explanation:
I did the math
28:35 because 28/7 is 4 and 35/7 is 5. So the answer is, 28:35.
Hope that helped :)
P(t)= A(1/2)^(t/h)
P(t)=10(1/2)^(16/8)
<em>(1/2)^(16/8) =.25</em>
P(t)=10(.25)
P(t)=2.5
Therefore the answer is B. 2.5mg.
(2x + 10)(x - 9)
2x(x - 9) + 10(x - 9)
2x(x) - 2x(9) + 10(x) - 10(9)
2x² - 18x + 10x - 90
2x² - 8x - 90
Answer:
(4, 13/5)
Step-by-step explanation:
Aquí, estamos encontrando el punto que divide el segmento en 1/4
supongamos que tenemos la proporción 1: 4 como a: b
Matemáticamente, el punto que divide el segmento será;
Coordenada x = (bx1 + ax2) / (a + b)
donde (x1, x2) = (3,8)
Al conectar estos valores, tenemos; (4 (3) + 1 (8) / (1+ 4) = (12 + 8) / 5 = 20/5 = 4
Coordenada y = (by1 + ay2) / (a + b) donde (y1, y2) = (1,9)
Conectando estos valores que tenemos; (4 (1) + 1 (9)) / (1 + 4) = (4 + 9) / 5 = 13/5
Por lo tanto, las coordenadas del punto es (4,13 / 5)
