Enter the equation of the line meeting the given conditions. Please put the equation instandard form.

just olya [345]

first, the slope is needed, which is 3-2/3--3 which is 1/6 and so this will be y=(1/6)x+b which then we'll input (3,3) which is 3=2+b or b=1 so the equation is y=(1/6)x+1

Find the value of x that makes this statement true

Brrunno [24]

$\frac{(-2)^{5x-3}}{(-2)^{2x}} =(-2)^{21}$

$(-2)^{5x-3-2x}=(-2)^{21}$ (The numerator and the denominator has same bases, therefore the powers will get subtracted. It is an exponential property)

$(-2)^{3x-3}=(-2)^{21}$

$3x-3=21$ (As the left hand side is equal to right hand side and the bases are on both the sides are equal too, we will equate their exponential power. Another property)

$x-1=7$

$x=8$ (After simplifying more, you'll get this)

Brilliant_brown [7]

Answer:

108.88

Step-by-step explanation:

Given that:

Equation of Regression line obtained for couple's IQ:

y=9.88+0.9x

x represents the IQ score of the husband

The best predicted IQ of wife Given that husband's IQ is 110

y = 9.88 + 0.9(110)

y = 9.88 + 99

y = 108.88
