Answer:

b=2.5

Step-by-step explanation:

every point on x axis has y coordinate =0

so bx=10

x=4

4b=10

b=10/4=5/2=2.5

2x - y = -2 . . . (1)
5x - 2y = -7 . . . (2)
From (1), y = 2x + 2 . . . (3)
Putting (3) into (2), gives:
5x - 2(2x + 2) = -7
5x - 4x - 4 = -7
x - 4 = -7
x = -7 + 4 = -3
y = 2(-3) + 2 = -6 + 2 = -4.

Therefore, the required answer is (-3, -4)

What are the zeros of the polynomial function? f(x)=x2−16x+48 Enter your answers in the boxes.

ioda

Answer:

$x_{1,2}=4,\ 12$

Step-by-step explanation:

Consider the polynmial function $f(x)=x^2-16x+48.$ The zeros of the polynomial function are the values of x at which f(x)=0. Solve the equation $x^2-16x+48=0:$

$D=b^2-4ac=(-16)^2-4\cdot 1\cdot 48=256-192=64=8^2,\\ \\x_{1,2}=\dfrac{-b\pm \sqrt{D}}{2a}=\dfrac{-(-16)\pm \sqrt{64}}{2\cdot 1}=\dfrac{16\pm 8}{2}=4,\ 12.$
