Answer:
f(x) = |x + 1| + 1
Step-by-step explanation:
A reflection over the y-axis followed by a reflection over x-axis is equivalent to a reflection about origin.
f(x) = -|x-1| -1
reflection over the x-axis:
-f(x) = (-1)*(-|x-1| -1) = |x-1| +1
reflection over the y-axis of the previous function:
-f(-x) = |-x-1| +1 = |x + 1| + 1
which is the reflection of f(x) about the origin
what is the missing constant term in the perfect sqaure that starts with x^2 - 4x
Answer:
The expression is; x^2 – 4c + 4
Step-by-step explanation:
For the expression to be a perfect square, let us say the constant term should be assigned as ⇒ c;
This creates of following expression;
x^2 - 4x + c
In order to be a perfect square, the discriminant needs to be zero ;
( - 4 )^2 - 4 * ( 1 )c = 0 ,
16 – 4c = 0 ,
4c = 16 ,
c = 4 ,
Solution; The expression is, therefore; x^2 – 4c + 4

What type of triangle, if any, can be formed with angle measures of 32, 126, and 32
-only an acute isosceles triangle
-either an acute isosceles triangle or an obtuse isosceles triangle
-no triangle
-only an obtuse isosceles triangle
Answer:
No triangle
Step-by-step explanation:
All triangles must have angles that measure up to 180 degrees. When you add 32, 32, and 126 you get 190. That means that no triangle can be formed.

plz help me. its " joseph runs 2/3 of a mile in 8 minutes. if joseph runs at that speed, how long will it take him to run 1 mile. and show your work". PLZ HELP ME ILL GIVE U 20 POINTS.
Answer:
He runs 2/3 mile in 8 mins, he runs one mile in 12 mins
It will take Joseph 12minutes to run 1 mile
Speed is defined as the ratio of the distance covered to the time taken.
If Joseph runs 2/3 of a mile in 8 minutes, then;
[tex]\frac{2}{3} miles = 8minutes[/tex]
In order to calculate the time it will take Joseph to run 1 mile, we can write:
[tex]1mile=x[/tex]
Divide both expressions
[tex]\dfrac{\frac{2}{3} }{1} =\dfrac{8}{x} \\\dfrac{2}{3}=\dfrac{8}{x}[/tex]
Cross multiply
[tex]2x=3 \times 8\\2x=24\\x=\frac{24}{2} \\x=12minutes[/tex]
This shows that it will take Joseph 12minutes to run 1 mile.

1.38 is the mean of the amount of rainfall over the course of the week
Answer:
1.4 inches (1 decimal place)
Step-by-step explanation:
To calculate the mean you get the sum of all the terms required and divide by the number of terms you summed up.
All of the terms in the table sum up to 29/3. 29/3 divided by 7 (number of days in a week) = 1.3809..., which you can round to 1.4 inches

Explain, with a test, why the two triangles in each figure are similar. Find the
unknown lengths.
Answer:
x = 3, y = 6
Step-by-step explanation:
In the figure attached,
If ΔADE and ΔABC are similar triangles, their corresponding sides will be in the same ratio.
By this property,
[tex]\frac{AB}{AD}=\frac{AC}{AE}=\frac{BC}{DE}[/tex]
[tex]\frac{AB}{AD}=\frac{AC}{AE}[/tex]
[tex]\frac{AD+BD}{AD}=\frac{AE+EC}{AE}[/tex]
[tex]\frac{3}{2}=\frac{x+1.5}{x}[/tex]
3x = 2x + 3
3x - 2x = 3
x = 3
Similarly, [tex]\frac{AB}{AD}=\frac{BC}{DE}[/tex]
[tex]\frac{3}{2}=\frac{y}{4}[/tex]

A car is traveling at a constant velocity. After two hours the car has traveled 110 miles.
After four hours the car has traveled 220 miles. Assuming a linear equation fits this
situation, find the distance that the car will travel after five hours.
Answer:
As the velocity is constant,
Distance covered in n hours = n × distance covered in 1 hr
Distance covered in 7 hrs = 7 × 110 = 770 miles

The theorems that verifies the ΔDEF ≅ ΔXYZ by SAS congruency Criteria.
What is Congruency?Congruent figures have sides that are the same length and angles that are the same measurement. In other words, congruent figures are those in which one figure superimposes another. Even when twisted or flipped, they perfectly fit together.
We have, two triangles DEF and XYZ.

What is the value of X in the figure?
Answer:
x = 360/7
Step-by-step explanation:
the sum of 3x and 2/4x is supposed to be 180 degrees.
1.- write it as an equation.
3x + 1/2x = 180
2.- Combine like terms.
3x + 1/2x = 7/2x
7/2x = 180
3.- divide.
180 / 7/2 = 360/7
Select all that are measures of angles that are coterminal with a -50° angle.
-770°
-530°
-410°
50°
310°
360°
410°
670°
Answer: -770, -410, 310, 670 degrees
Step-by-step explanation:
Coterminal angles are angles that are have the same sides ... they are essentially the same angle, but are, for example, rotated an extra 360 degrees.
You can add/subtract 360 degrees to check if angles are coterminal:
-770 = -50 - 360 - 360 -- YES, it is coterminal with a -50 degree angle.
-530 [tex]\neq[/tex] -50 - 360 ... -- NO
-410 = -50 - 360 -- YES
50 [tex]\neq[/tex] -50 + 360 ... -- NO
310 = -50 + 360 -- YES
360 [tex]\neq[/tex] -50 + 360 ... -- NO
410 [tex]\neq[/tex] -50 + 360 ... -- NO
670 = -50 + 360 + 360 -- YES
2. The lengths of two insects are given below.
Ladybug: 10 millimeters
Walking stick: 30 centimeters
What is the difference in length of these two insects in millimeters
A 70 mm
B 20 mm
C 290 mm
D 2,990 mm
The conversion rate of millimetres to centimetres is 10 = 1 (Meaning 10 millimetres will equal one centimetre).
Knowing this, we can convert the centimetres to millimetres by multiplying by 10.
30 x 10 = 300
So a walking stick is 300 millimetres long.
To find the difference, we need to subtract the larger number from the smaller one.
300 - 10 = 290
Therefore the answer is 290mm.
