Sam completed the square for the quadratic equation y=12x2−2x+3 in order to determine the minimum value of the equation, as show

n.
Step 1: y=12(x2−1x+32)
Step 2: y=12(x2−x+14−14+32)
Step 3: y=12((x−12)2−14+32)
Step 4: y=12((x−12)2+54)
Step 5: y=12(x−12)2+58
What mistake, if any, did Sam make?

Well, 3=2x+10, so that means -7=2x , to solve for x I will just divide, so x= -3.5

Determine whether the graphs of the given equations are​ parallel, perpendicular, or neither. (#2)
masha68 [24]
Look at the slope. if the slopes are the same, the two lines are parallel. if the slopes are negative reciprocals, the lines are perpendicular. otherwise, neither, the two lines will intersect.
6y=x+9
y=(1/6)x+(9/6)
the slope is 1/6, while the second line has a slope of 7, so the two lines have different slopes, so choice D is correct.

In 2019, the average temperature in some parts of the
Mice21 [21]

Answer:

-13.315° F

Step-by-step explanation:

Number of years from 2019 to 2050 is 2050 - 2019 = 31 years

Increase in temperature per year = 0.135

Increase in temperature for 31 years = 0.135*31 = 4.185

Average temperature in 2050 = -17.5 + 4.185 = -13.315° F

Answer:

x^2-4x+3

Step-by-step explanation:

Since the zeroes of the quadratic are 1 and 3, we can set up an equation in factored form:

(x-1)(x-3)

=x^2-4x+3

We can further check that this is the right answer by evaluating it at the vertex:

(2)^2-4*2+3=-1

Since that corresponds to the graph, the answer is x^2-4x+3

If someone can do both I’d appreciate it! I’ve been up for awhile trying to fingers these out.
Lilit [14]

Answer:

3. AGH= 150

4. CHF= 110

Step-by-step explanation:

3. AGH corresponds to CHF, so they equal the same. AGH = 150

4. BGE is vertical to AGH, so they equal the same AGH = 110. AGH corresponds to CHF, so they equal the same. CHF=110.
