Answer:

1. 70

2. 105

Step-by-step explanation:

1. A triangle always adds up to 180° so you would add both the angles you know 55° plus 55° which equals 110° then subtract it from 180° and you should get 70°

2. Add 40° and 35° which equals 75° then subract it from 180° which is 105°

The point 3,4 lies on the graph of f(x)= sqrt(2x+a). Which ordered pair below lies on the graph of g(x)=1/2sqrt(2x+a)?

Rina8888 [55]

$(3;\ 4);\ f(x)=\sqrt{2x+a}\\\\\sqrt{2\cdot6+a}=4\\\sqrt{12+a}=4\ \ \ /^2\\12+a=16\\a=16-12\\a=4\\\\f(x)=\sqrt{2x+4}$

$g(x)=\frac{1}{2}\sqrt{2x+4}\\\\a)\ \left(\frac{3}{2};\ 2\right)\\R=\frac{1}{2}\sqrt{2\cdot\frac{3}{2}+4}=\frac{1}{2}\sqrt{3+4}=\frac{1}{2}\sqrt7;\ L=2;\ L\neq R\\\\b)\ \left(\frac{5}{2};\ \frac{3}{2}\right)\\R=\frac{1}{2}\sqrt{2\cdot\frac{5}{2}+4}=\frac{1}{2}\sqrt{5+4}=\frac{1}{2}\sqrt9=\frac{1}{2}\cdot3=\frac{3}{2};\ L=\frac{3}{2};\ L=R$

$c)\ (3;\ 2)\\R=\frac{1}{2}\sqrt{2\cdot3+4}=\frac{1}{2}\sqrt{6+4}=\frac{1}{2}\sqrt{10};\ L=2;\ L\neq R\\\\d)\ (27;\ 8)\\R=\frac{1}{2}\sqrt{2\cdot27+4}=\frac{1}{2}\sqrt{54+4}=\frac{1}{2}\sqrt{58};\ L=8;\ L\neq R\\\\Answer:B$

4a. If (11+x) is positive, but (4+x) is negative, what is one number that x could be?

sattari [20]

Answer:

Step-by-step explanation:

x has to be equal to or less than a -5 to get (4 + x) to be a negative number.

x has to be equal to or greater than -10 for (11 + x) to be a positive number.

Therefore, any number between -10 and -5 will work.
