A negative number is divided from both sides of an inequality.
The sign of every term on both sides of the inequality are changed to its opposite.
Answer: it should be 1 and 2
Step-by-step explanation:
Adding and subtracting equal amounts to both sides should balance them out.
Answer:
A negative number is added to both sides of an inequality.

Answer:
A. x=8 y=21
Step-by-step explanation:
line l and line m are parallel, and both angles that have x in the values are on the same side, so they are equal to each other.
7x+12=12x-28
+28 +28
7x+40=12x
-7x -7x
40=5x
/5 /5
8=x
Since A is the only choice that has x=8, it must be the right answer.
Answer:
x = 8, y = 21
Step-by-step explanation:
parallel means they're equal so..
7x + 12 = 12x - 28
-7x -7x
12 = 5x -28
+28 +28
40 = 5x
8 = x
plug in 8 to 12x - 28
12(8) - 28
96 - 28 = 68
180 - 68 = 112
9y - 77 = 112
+77 +77
9y = 189
y = 21
According to the graph, what is the experimental probability of selecting the letter T?
1/20
4
1/4
1/5
Answer: the answer is 1/5 I put 4 and got it wrong, after submitting the test it showed me the answer
Experimental probabilities are based on the results of an experiment.
The experimental probability of T is (d) 1/5
From the graph, we have:
[tex]\mathbf{M = 6}[/tex]
[tex]\mathbf{A = 3}[/tex]
[tex]\mathbf{T = 4}[/tex]
[tex]\mathbf{H = 7}[/tex]
So, the experimental probability of T is:
[tex]\mathbf{P(T) = \frac{T}{M + A + T + H}}[/tex]
This gives
[tex]\mathbf{P(T) = \frac{4}{6 + 3 + 4 + 7}}[/tex]
[tex]\mathbf{P(T) = \frac{4}{20}}[/tex]
Simplify
[tex]\mathbf{P(T) = \frac{1}{5}}[/tex]
Hence, the experimental probability of T is (d) 1/5

A city planner uses a coordinate grid to model the streets of a city. Each unit on the coordinate grid represents one city block. City hall is located at (0,0).The downtown area is represented by rectangleABCD, which has the vertices listed below. A(9,9) B(9,−2) C(−8,−2) D(−8,9) What is the perimeter of the downtown area?
Answer:
The perimeter of the downtown area is 56 units.
Step-by-step explanation:
From Geometry we know that perimeter ([tex]p[/tex]), dimensionless, is the sum of the lengths of the rectangle, that is, its 4 sides:
[tex]p = AB + BC + CD + DA[/tex] (1)
Where [tex]AB[/tex], [tex]BC[/tex], [tex]CD[/tex] and [tex]DA[/tex] are the sides of the rectangle, dimensionless.
Each side length is determined by Pythagorean Theorem:
[tex]AB = \sqrt{(9-9)^{2}+(-2-9)^{2}}[/tex]
[tex]AB = 11[/tex]
[tex]BC = \sqrt{(-8-9)^{2}+[-2-(-2)]^{2}}[/tex]
[tex]BC = 17[/tex]
[tex]CD = \sqrt{[-8-(-8)]^{2}+[9-(-2)]^{2}}[/tex]
[tex]CD = 11[/tex]
[tex]DA = \sqrt{[9-(-8)]^{2}+(9-9)^{2}}[/tex]
[tex]DA = 17[/tex]
Then, the perimeter of the downtown area is:
[tex]p = 11+17+11+17[/tex]
[tex]p = 56[/tex]
The perimeter of the downtown area is 56 units.
Answer:
56 units
Step-by-step explanation:
in order to lure new customers to a credit card, a bank is offering an initial cash back award, plus cash back amounting to a percentage of the value of all purchases made with the card. If p is the value if all purchases made with the card and c is the amount of cash back, which of these equations does the graph represent?
Answer:
c = 0.03p + 150
Step-by-step explanation:
Let the equation of the line representing the relation between cash back and value of purchases be,
c = mp + b
Where m = slope of the line = rate of change in cash back earned
b = y-intercept = cash back already earned
Slope of the line = [tex]\frac{\triangle p}{\triangle c}[/tex] = slope of the line passing through points (0, 150) and (2000, 210)
= [tex]\frac{210-150}{2000-0}[/tex]
= [tex]\frac{60}{2000}[/tex]
= 0.03
And 'b' = y-intercept = 150
Therefore, equation represented by the graph will be,
c = 0.03p + 150

Answer:
y=3x+5
Step-by-step explanation:
We know the slope-intercept form is y=mx+b.
To find the slope:
11-(-1)/2-(-2)=12/4
12/4=3
To find the y-intercept, we can look at the table pattern. If x is 0, then y must equal 3.
Therefore our final answer is y=3x+5

Answer:
angle 1= 122
Step-by-step explanation:
We know this is an isosceles triangle because of the two marks indicating that the lines have the same measure and therefore have the same angle measurement as well.
Frist let's find the the 2 smaller sides by subtracting 64 from 180 and dividing by 2 (both sides are the same).
180-64=116, 116/2=58,
Now we know the measure of the smaller angles, and notice that the smaller angle on the forms a linear pair (both add up to 180 degrees) with angle 1
so, 180-58= angle 1
Angle 1= 122

A submarine starts at the surface of the water and then travels 95 meters below sea level in 19 seconds. If the submarine traveled an equal distance each second, what integer gives the distance traveled each second? a. –1805 c. –5 b. 1805 d. 5
Answer:
-5
Step-by-step explanation:
Given that:
Total distance traveled from surface of water = 95 meters
Total travel time = 19 seconds
If equal distance Is traveled per second :
Distance traveled per second :
Total distance covered / total time taken
95 meters / 19 seconds
= 4.842 meters / second
Since it travels below sea level ( negative).
Hence distance traveled per second to the nearest integer = - 5 m/s
