SOMEONE PLS HELP ASAP!!!

ladessa [460]

Answer: $h(x)=10(0.4)^x$

Step-by-step explanation:

The exponential function h, represented in the table, can be written as $h(x)=ab^x$

From table, at x=0, h(x) =10

Put theses values in equation,, we get

$10=a.b^0\\\\\Rightarrow\ 10= a (1)\\\\\Rightarrow\ a= 10$

Also, for x= 1 , h(x) = 4, so put these values and a=10 in the equation , we get

$4=10b^1\\\\\Rightarrow\ b=\dfrac{4}{10}\\\\\Rightarrow\ b= 0.4$

Put value of a and b in the equation ,

$h(x)=10(0.4)^x$ → Required equation.

x-15+x = 85
2x-15 = 85
2x = 100

Formúla General a) 4x²=9x-2=0 b) X²+8x-84=0

makkiz [27]

Answer: a) $x=\dfrac{-9 \pm\sqrt{113} }{8}$

b) x₁ = - 14; x₂ = 6.

Step-by-step explanation:

a) 4x² + 9x - 2 = 0

$x=\dfrac{-b \pm \sqrt{b^{2}-4ac } }{2a} \\\\a=4; \: \: b=9; \: \: c=-2\\x =\dfrac{-9 \pm \sqrt{9^{2}-4 \cdot 4 \cdot (-2) } }{2 \cdot 4} =\dfrac{-9 \pm\sqrt{113} }{8}$

b) x² + 8x - 84 = 0

$x=\dfrac{-b \pm \sqrt{b^{2}-4ac } }{2a} \\\\a=1; \: \: b=8; \: \: c=-84\\\\x =\dfrac{-8 \pm \sqrt{8^{2}-4 \cdot 1 \cdot (-84) } }{2 \cdot 1} =\dfrac{-8 \pm\sqrt{400} }{2}=\dfrac{-8 \pm 20}{2} =-4 \pm 10\\\\x_{1} =-14\\x_{2} =6$
