I really need this 1. Graph y= 1/2x–3.

2. Xin graphs the equation y=4x – 6 . Select all statements about Xin's graph that are true. The graph is a curved line. The line passes through the origin. The line passes through the point (0, 6) . The slope of the line is 4. The y-intercept of the line is –6 .

3. What is the equation of this line? y=−2/3x y=−3/2x y=2/3x y=3/2x

4. What is the equation of this line? y=1/2x−2 y=−2x−2 y=2x−2 y=−1/2x−2

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
