Noah is solving the inequality 7x + 5 > 2x + 35. First, he solves the equation 7x + 5 = 2x +35 and gets x = 6. How does the solution to the equation help Noah to solve the inequality? Explain your reasoning.​

Answer:

The point is not a solution for both inequalities, so the point is not a solution for the system of inequalities.

Probabilities

One approach to estimating the probability of occurrence of an event is to record the number of times that event happens (e) and compare it with the total number of trials (n).

The probability can be estimated with the formula:

[tex]\displaystyle P=\frac{e}{n}[/tex]

And the probability that the event doesn't occur is

Q = 1 - P

Paulo arrives on time to school e=53 times out of n=79 times. The probability that he arrives on time is:

[tex]\displaystyle P=\frac{53}{79}[/tex]

P = 0.67

And the probability he arrives late is:

Q = 1 - 0.67 = 0.33

Answer D

Step-by-step explanation: I started from T, go from T to T'. Look at T, count 7 units to the right and that will be 7 positive. Then count 3 units down, which is -3. The translation would be (7,-3) or "D".

Answer:

y =-2/3x

x = 1

Step-by-step explanation:

adding both equations and then we find the value of y which is given below

y = -2/3x

and then putting the value of y in any above equation then we find the value of X which is given below

X = 1

In 3 min = 4 1/2

10 min = 15

If you multiply both of the snakes speed by the specific amount of minutes and then subtract both of the sums you'll get the answer :)

Answer:

(5y+11)²

Step-by-step explanation:

The given expression is :

25y²+110y+121

We need to factors of the given expression.

We know that, (11)² = 121

5² = 25

We can write the given expression as :

25y²+110y+121 = (5y)² + 2(5y)(11) +11²

Using identity : (a+b)² = a²+2ab+b²

25y²+110y+121 = (5y+11)²

Hence, the factors of 25y²+110y+121 is (5y+11)².

Answer:

Area of sector = 117.6 cm²

Step-by-step explanation:

Radius of sector r = 10 cm

Angle Ф = 135°

We need to find Area of sector

The formula used is: [tex]\mathbf{Area\:of\:Sector=\frac{\theta}{360^{\circ}}\times \pi r^2}[/tex]

Where Ф is the angle, and r is the radius.

Putting values and finding area of sector

[tex]\mathbf{Area\:of\:Sector=\frac{\theta}{360^{\circ}}\times \pi r^2}\\Area\:of\:Sector=\frac{135}{360}\times 3.14 (10)^2\\Area\:of\:Sector=0.375 \times 3.14 \times 100\\Area\:of\:Sector=117.75[/tex]

Now, rounding off answer to 1 decimal place:

[tex]Area\:of\:Sector=117.6\: cm^2[/tex]

So, Area of sector = 117.6 cm²

Answer:

c I guess tell me if I am wrong yall

Step-by-step explanation:

We have AB = 7, Angle ABC = 70°

and Angle ACB = 90°.

Angle BAC = 180° - 70° - 90° = 20°

(Sum of angles in a triangle = 180°)

Using Trignometry,

AC = 7sin70° = 6.58.

BC = 7cos70° = 2.39.

Answer:

TRUE and FALSE  (please look at step-by-step)

Step-by-step explanation:

How to know if it's true or false, you just simply plug in the given numbers to the x and y values.

x = -3

y = 11

for the x - 3y = -36 equation:

-3 -3(11) = -36

-3 - 33 = -36

This equation is true.

for the 3x + 4y = 48 equation:

3(-3) + 4(11) = 48

-9 + 44 = 35

This equation is false.

(5y-4)-180=3y

5y-184=3y

5y-3y=184

2y=184

y=92

2x+13=3*92

2x=263

x=131.5

704.1 -   98.35=605.75

Answer:  B) neither

================================================

Let's isolate y in the first equation. This way we can find the slope.

x-2y = 4

-2y = 4-x

-2y = -x+4

y = (-x+4)/(-2)

y = -x/(-2) + 4/(-2)

y = (1/2)x - 2

This matches with y = mx+b form with m = 1/2 being the slope.

The slope of y = 2x-2 is m = 2

------------------------------

The slope of the first line is 1/2 and the slope of the second line is 2.

Since the two slopes (1/2 and 2) are not equal, this means the lines are not parallel.

Also, the two slopes do not multiply to -1, so the lines aren't perpendicular either.

This leads to B) neither as the final answer.
