Step-by-step explanation:
first of all I have to say the range should be " y >= 0" and not just "y > 0", because x can be 0, and then y is 0 too.
but under the the same assumption of the definition above, the correct answer is B, y < 0.
because a×|x| means we multiply a negative value with a positive value. and that result is always a negative value.
so, it cannot be C.
and it cannot be A, because
if |x| < 1 (e.g. 0.5), then a×|x| > a, as e.g. -1 > -2
Find the slope of the line that passes through the given two points.
Answer:
Step-by-step explanation:The slope formula is used to calculate the slope if you are given two points. Remember that slope is defined as rise/run. Which translates to the rise divided by the run. The slope formula will allow us to take the change in the rise and divide by the change in the run.
1/16+3/18? Find the lowest common denominator?
Answer:
48 is the lowest common denominator.
Step-by-step explanation:
[tex]\frac{1}{16}+\frac{3}{18}[/tex]
[tex]\frac{18+16(3)}{16*18}[/tex]
[tex]\frac{66}{288}[/tex] /2
[tex]\frac{33}{144}[/tex] /3
[tex]\frac{11}{48}[/tex]
Therefore the lowest common denominator of both the fractions is 48.
Ann and her friends are visiting chocolate shops in Hampton. They take a cab from one chocolate shop to another. On a map, the two are separated by 1.5 inches. The scale of the map is 3 inches = 5.2 miles. In real life, what is the distance between the two chocolate shops?
Answer:
Ann and her friends traveled 2.6 miles to go to another chocolate shop in the cab.
Step-by-step explanation:
As we know, that 1.5 is half of 3. And to understand that better. Let's do this
1.5--> 15
3-->30
30-15=15. So, 15 (1.5), is half of 30. (3)
We know that 3 inches on the map equals 5.2 miles, and if we have to basically find the half of 5.2 to get the answer, then, let's do this.
5.2÷2=2.6
So, hence, 2.6 miles is our answer.
Ann and her friends traveled 2.6 miles to go to another chocolate shop in the cab.

Answer:
3rd graph
Step-by-step explanation:
3m ≥ 21 whenever you see '≤ or ≥' then you know the circle must be filled
divide each side by 3 to isolate 'm':
m ≥ 7 This inequality, when graphed, should have a closed circle on the number 7 and the shading would be to the right because the symbol is indicates all values "greater than" 7

Sheena purchased 12 meters of cloth. She used 3 7/9 meters of cloth for curtains and 2 4/7 for a bed sheet. How much cloth does she have left
Answer: Sheena has 5 41/73 meters of cloth left.
Step-by-step explanation:
First, add 3 7/9 and 2/47 to add them follow these steps:
Convert any mixed numbers to fractions,
3 7/9 = 34/9
2 4/7 = 18/7
Next: Multiply the new fractions,
(34 x 7) + (18 x 9)
9 x 7
After multiplying, solve the new problem,
238 + 162
63
Your new fraction should be,
400/63
Convert 400/63 to a mixed number, which is 6 22/63.
After that subtract 12 - 6 22/63.
To find the answer, you do the same thing.
Convert any mixed numbers to fraction
12 = 12/1
6 22/63 = 400/63
Then multiply the fraction,
(12 x 63) - (400 x 1)
1 x 63
After multiplying, solve your new problem,
756 - 400
63
Your new fraction should be,
356/63
Convert t356/63 into a mixed number, which is 5 41/63
So, your answer should be 5 41/63.
Hope this helped!!

One interior angle of a regular polygon is 175 degrees. What is the measure of one exterior angle?
The exterior angle of the regular polygon is: 5°
What is an Interior Angle of a Regular Polygon?Each interior angle of a regular polygon = (n - 2)180/n
Given:
interior angle = 175°
Thus:
175 = (n - 2)180/n
175n = 180n - 360
175n - 180n = -360
-5n = -360
n = 72
Thus,
Measure of one exterior angle = 360/72 = 5°

a support wire to a newly planted tree makes a 32° angle with the ground.
determine the angle made by the wire at the point of contact to the tree by finding the complement of 32°
Answer:
58°
Step-by-step explanation:
Since the angle made by wire with ground and at the point of contact to the tree are complementary.
So,
Required angle = 90° - measure of the angle formed by wire with ground
Required angle = 90° - 32° = 58°

A triangle has exterior angle measures of 2x°, 2x°, and x°. Find the value of x.
Answer: 72
Step-by-step explanation:
The sum of exterior angles of a triangle is equal to 360º.
For the given triangle:
[tex]2x[/tex]°+[tex]2x[/tex]°[tex]+x[/tex]° = 360
Solve x in the equation above:
[tex]5x=360[/tex]
Divide both sides of the equation into 5:
[tex]\frac{5}{5}x=\frac{360}{5}[/tex]
x=72
Then, the value of x is 72

Answer:
[tex]x[/tex] = 29.64 to the nearest hundredth
Step-by-step explanation:
The three sides of a right-angled triangle have specific names:
The hypotenuse (H) is the longest side. It is opposite the right angle.The opposite side (O) is opposite the angle in question.The adjacent side (A) is next to the angle in question.The 3 trigonometric ratios are:
[tex]sin(\theta)=\frac{O}{H} \\\\cos(\theta)=\frac{A}{H} \\\\tan(\theta)=\frac{O}{A}[/tex]
For the given triangle we are given the angle and the side that is OPPOSITE to the angle, and need to find the hypotenuse.
Therefore, we would use the trig ratio: [tex]sin(\theta)=\frac{O}{H}[/tex]
Substituting the values from the triangle: [tex]sin(35)=\frac{17}{x}[/tex]
Multiply both sides by [tex]x[/tex]: [tex]xsin(35)=17[/tex]
Divide both sides by [tex]sin(35)[/tex]: [tex]x=\frac{17}{sin(35)}[/tex]
Therefore, [tex]x[/tex] = 29.63859553...
So [tex]x[/tex] = 29.64 to the nearest hundredth
