Alvin is 9 years older than Elga. The sum of their ages is 89. What is Elga's age?

Mekhanik [1.2K]

Answer:

Alvin: 49

Elga: 40

Step-by-step explanation:

The equation is 89 = x + (x-9).
Remove the parenthesis and combine the like terms. 89 = 2x - 9
Add 9 on both sides. 98 = 2x
Divide by 2 on both sides. x = 49
49 is the age of Alvin. (49-9) 40 is the age of Elga.

Wich expression can be used to find the slope of a line containing the points (-3,2) and (7,-1)

docker41 [41]

$A(x_1;\ y_1);\ B(x_2;\ y_2)\\\\\text{The slope:}\ m=\dfrac{y_2-y_1}{x_2-x_1}$

$\text{We have:}\\(-3;\ 2)\to\ x_1=-3;\ y_1=2\\(7;\ -1)\to x_2=7;\ y_2=-1$

$\text{substitute}\\\\m=\dfrac{-1-2}{7-(-3)}=\dfrac{-3}{10}=-\dfrac{3}{10}$

One x-intercept for a parabola is at the point (1,0). Use the factor method to find the other x-intercept for the parabola defin

Hoochie [10]

First simplify the equation of parabola $y=-5x^2+15x-10$ in the following way:
$D=(15)^2-4\cdot (-5) \cdot (-10)=225-200=25, \\ \sqrt{D}=5, \\ x_{1,2} = \dfrac{-15\pm 5}{2\cdot(-5)} = 2, 1 \\ -5x^2+15x-10=-5(x-1)(x-2), \\ y=-5(x-1)(x-2)$ .
You can see that if x=1 or x=2, then y=0. Two points of intersection with x-axis are (1,0) and (2,0).
