10 = 2(1)+b

10=2+b

-2 -2

b = 8

y intercept = 8

equation: y = 2x+8

yes it is proportional because it has a constant rate of change or slope

Answer:

For the above to be considered a binomial experiment, it must be guaranteed:

1. That each child must offer one of two answers: yes, if I buy soda (pop) at least once a week / no, I do not buy soda (pop) at least once a week.

2. That the fact that a child, in particular, buys soda (pop) at least once a week, has no relationship (dependence) with another child buying soda (pop) at least once a week. week.

3x+8 •59 solve for x

Marina86 [1]

1) Let's solve for x, writing this equation.

3x +8*59 =0

3x +472=0 Subtract 472 from both sides

3x = -472

x= -472/3 or -157.33

2) So the answer is x= -472/3

Prove that the triangle EDF is isosceles. Give reasons for your answer.

Gekata [30.6K]

Answer:

$\triangle EDF$ is isosceles.

Step-by-step explanation:

Please have a look at the attached figure.

We are given the following things:

$\angle EDF = y$

$\text{External }\angle DFG = 90 +\dfrac{y}{2}$

Let us try to find out $\angle E$ and $\angle DFE$ . After that we will compare them.

Finding  $\angle DFE$ :

Side EG is a straight line so $\angle GFE = 180$

$\angle GFE$ is sum of internal $\angle DFE$ and external $\angle DFG$

$\angle GFE = 180 = \angle DFE + \angle DFG\\\Rightarrow 180 = \angle DFE + (90+\dfrac{y}{2})\\\Rightarrow \angle DFE = 180 - 90 - \dfrac{y}{2}\\\Rightarrow \angle DFE = 90 - \dfrac{y}{2} ....... (1)$
