Answer 1

Answer:

(1,4)

Step-by-step explanation:

Answer 2

Answer: x = 1, y = 4

Steps: 3y + 4x = 16, -2x + y = 2

Isolate y for 3y + 4x = 16: y = (16 - 4x ÷ 3)

Substitute y into the other equation (-2x + y = 2): -2x + (16 - 4x ÷ 3) = 2

Simplify: 16 - 10x ÷ 3 = 2

Isolate x for 16 - 10x ÷ 3 = 2: x = 1

Substitute x = 1 into y = (16 - 4x ÷ 3): y = 16 - 4x · 1 ÷ 3

y = 4, x = 1

Answer:

Your answer is: x < 84

Step-by-step explanation:

Hope this helped : )

Answer:

x<84

Step-by-step explanation:

In this problem, we can't find a specific value of x. In this case, we will find a range of value suitable for x.

[tex]\frac{x}{6} -6 < 8[/tex]

Add 6 to both sides

[tex]\frac{x}{6} <14[/tex]

Multiply 6 to both sides

x<84

Answers

Answer:

150 miles

Step-by-step explanation: The distance from Page to Flagstaff can be shown with the equation d = r * t, or distance = rate * time. In this case, the rate is 60 mph, and the rate is 2.5 h. Plugging that into the equation you get d = 2.5(60) = 150, giving you your distance.

solve for y: ax+by=c

Answers

Answer:

y=c-ax/b

Step-by-step explanation:

Subtract ax from both sides.

by=c−ax

Divide both sides by b

by/b=c-ax/b

Dividing by b undoes the multiplication by b.

y=c-ax/b

Answer: y=c-ax/b

Step-by-step explanation:

Subtract ax from both sides.

by=c−ax

Divide both sides by b

by/b=c-ax/b

Dividing by b undoes the multiplication by b.

y=c-ax/b

What is the length of the third side of the window frame below?
A. 10 inches
B. 12 units
C. 16 units
D. 20 units

Answers

Answer:

20 units

Step-by-step explanation:

a^(2)+b^(2)=c^(2)

48^(2)+b^(2)=52^(2)

2304+b^(2)=2704

2304-2304+b^(2)=2704-2304

b^(2)=400

\sqrt(b^(2))=\sqrt(400)

b=20

therefore,20 is the length of the unknown side

Step-by-step explanation:

determine the effects on the graph of the parent function f(x)=x+10 when g(x)=0.3f(x)

Answers

Answer:

First, remember the definition of a vertical contraction/dilation.

If we have a function f(x), and we dilate it with a factor A, such as:

g(x) = A*f(x).

If A is larger than 1, then we are dilating the graph of f(x)

if A is smaller than 1, then we are contracting the graph of f(x).

In this case we have:

f(x) = x + 10 and g(x) = 0.3*f(x) = 0.3*x + 0.3*10 = 0.3*x + 3.

A = 0.3

then we have a contraction.

From this, we can conclude that the effects of this transformation in the graph will be that the graph of g(x) will be a vertical contraction of the graph of f(x).

(Where contracting means that in a given interval [x1, x2] the associated interval [f(x1), f(x2)] will be larger than [g(x1), g(x2)])

Below you can see both graphs, and see the difference between them, where green is f(x) and blue is g(x)

Joseph type 60 words in 1 and 1/3 minutes what is average typing speed in words per minute

Answers

Answer:

45 words per minute

Step-by-step explanation:

60 / 1 [tex]\frac{1}{3}[/tex]

The average typing speed of Joseph in words per minute is 45 words per minute.

What is an average speed?

The average speed is the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity.

Now it is given that,

Number of words = typed 60 words

Time taken = 1 and 1/3 minutes

⇒ Time taken = 4/3 minutes

Thus, Average typing speed = Number of words / Time taken

⇒ Average typing speed = 60 / (4/3) words per minute

⇒ Average typing speed = 45 words per minute

Thus, the average typing speed of Joseph in words per minute is 45 words per minute.

Describe the type of gold used for trade in Ghana. please help Use the passage below to answer all parts of the question that follows.No ruler took more liberties with his religion than Akbar, the greatest of the Mughals, the Muslim dynasty that dominated India between the early 16th and 18th centuries. Like Ashoka and Gandhi, Akbar constructed a religious ideology that served to hold together a diffuse polity as it fed his own soul.It began with pragmatic policies of tolerance. Akbar had inherited the throne, at the age of 13, in 1556. In 1579 he abolished the jiziya, a tax imposed on all but the poorest non-Muslims. This was the most notable in a series of measures to recruit the Hindu majority and others to the cause of unifying and expanding his empire. He could be ruthless: his troops massacred 20,00025,000 non-combatants after a four-month siege of Chitor, a nearly impregnable Hindu fortress in Rajasthan. But he preferred incentives to coercion. He defeated the war-like Rajputs, but gave them rank and married their princesses, who were permitted to conduct Hindu rites in the harem. The Mughal-Rajput alliance was a bulwark of his empire."Multicultural Akbar, The Economist, 1999a) Explain ONE specific political development that resulted from the conditions created by the religious policies described in the passage.b) Explain ONE specific change to Muslim-Hindu relations that resulted from the conditions created by the religious policies described in the passage.c) Explain ONE specific consequence of the policies described in the passage on religious minorities.
