How would you graph y = -3x + 4? (With visual, please; will give brainliest!)

Answer:

The second option you listed: x + y = 4 gives the same line as H, and therefore renders infinite number of solutions (as many as every point on the line)

Step-by-step explanation:

We need to look for the equation that exactly matches the given one :

2 x + 2 y = 8

notice dividing both sides of this equation by "2" we get:

x + y = 4

SO this equation represents exactly the same line as 2 x + 2 y = 8 does, and therefore their graphs overlap completely

Answer:

5760+ 90π m³       or     ≈ 6042.74 m³

Step-by-step explanation:

V = πr²h + (l×w×h)

  = π3²10 + (20×16×18)

  = 90π + (5760)

  = 6042.7433388

Answer:

[tex]g(x)=f(-x)=\frac{3}{8}(4)^{-x}[/tex]

Step-by-step explanation:

The pre-image is

[tex]f(x)=\frac{3}{8}(4)^{x}[/tex]

To make a reflection across the y-axis, we need to apply the transformation

[tex](x,y) \implies (-x,y)[/tex]

Which give the function

[tex]g(x)=f(-x)=\frac{3}{8}(4)^{-x}[/tex]

Therefore, the right answer is the last choice.

Answer: the answer is C. 80°

Step-by-step explanation:

= 360 - 110 - 90

=160°

b=1/2 (160)

b=80°

Answer:

C. 80 degrees

Step-by-step explanation:

The measure of the given arcs are 90 and 110.

Subtract those values from 360

= 360 - 90 -110

= 160

The angle b is half of 160 degrees, the measure of the arc that intercepts it.

Therefore, it measures 80 degrees.

Answer: 25%

Step-by-step explanation: So, I think we know it's 50% chance to get heads or tails. But what's the chance of getting heads two times in a row....let's see...

[tex]\frac{1}{2} * \frac{1}{2} = \frac{1}{4}[/tex]

Let's turn [tex]\frac{1}{4}[/tex] into a decimal...

1 ÷ 4 = 0.25

0.25 * 100 = 25

= 25%

Thus, you have a 25% to get heads two times in a row...I hope this helps!

Answer: the system of inequalities are

x + y ≤ 14

18x + 38y = 342

Step-by-step explanation:

Let x represent the number of iPad chargers sold.

Let y represent the number of keyboards sold.

At the end of the day, he knows he sold a maximum of 14 items. This is expressed as

x + y ≤ 14

If he

charged $18 for each iPad charger (x) and $38 for each keyboard (y) and earned a total of $342, the expression would be

18x + 38y = 342

Answer:

20

Step-by-step explanation:

Because this is a right triangle, you can use the Pythagorean Theorem, a^2 + b^2 = c^2.  a and b are your legs and c is your hypotenuse, so you have 21^2 + b^2 = 29^2. This equals to 441 + b^2 = 841. subtract 441 from both sides and you are left with b^2 = 400. take the square root of both sides to get your answer b = 20, or x = 20.

Answer:

x = 20

Step-by-step explanation:

→You can use the Pythagorean Theorem to solve this:

[tex]a^2 +b^2=c^2[/tex]

→The "a," and "b," are the legs, 21 and x, while the "c," is the hypotenuse, 29. In this case, we are trying to find the value of a leg:

[tex]21^2+b^2=29^2[/tex]

[tex]441+b^2=841[/tex]

→Subtract 441 from both sides:

[tex]b^2=400[/tex]

→To get "b," by itself, you must take the square root of both sides, like so:

[tex]\sqrt{b^2} =\sqrt{400}[/tex]

[tex]b = 20[/tex]

Answer:

a) 2*a*b - a/b

b)  c² + d + 2*c*d

c)  c + c²

d) (1 + b)/(2*b)

e)  p*q - 3*(p+q)

f) n²/(n+5)³

Step-by-step explanation:

We can divide each statement into its parts, as follows:

a) The difference between:

b) The sum of:

c) The sum of:

d) The quotient of:

e)

f) The quotient of:

All the algebraic expressions are written as,

a) 2ab - (a/b)

b) c² + d + 2cd

c)  c + c²

d) (1 + b)/(2b)

e)  pq - 3(p+q)

f) n²/(n+5)³

Used the method of a mathematical expression,

Mathematical expression is defined as the collection of numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, simplify all the expressions for mathematical form as,

a) The difference between twice the product of a and b and the quotient of these numbers.

Here, twice the product of a and b is,

2 × (ab)

And, the quotient of these numbers is,

a/b

Hence, it can be written as,

[tex]2ab - \dfrac{a}{b}[/tex]

b) The sum of squares of c and d increased by twice their product.

Here, d increased by twice their product is,

d + 2cd

And, The sum of squares of c and d increased by twice their product is,

c² + (d + 2cd)

c) The sum of a number c and its square is,

c + c²

d) Now, the number that is 1 greater than a number b is,

1 + b

And the number that is twice as large as b,

2b

So, The quotient of the numbers,

(1 + b)./2b

e) Now, The product of two numbers, p, and q is,

p × q

And, it is decreased by three times their sum:

p × q - 3 (p+q)

pq - 3 (p + q)

f) Now, the square of a number n is, n²

and the cube of n increased by 5 is, (n+5)³

So, The quotient is,

n² / (n + 5)³

Solution:

Cost of Dunkin Donuts gift card with Daniel = $50

Amount spent by Daniel per day = $3.50

Cost of Dunkin Donuts gift card with David = $100

Amount spent by David per day = $6

Amount left with Daniel after x days = [tex]\$(50-3.50x)[/tex]

Amount left with David after x days = [tex]\$(100-6x)[/tex]

According to question,

Amount left with Daniel after x days > Amount left with David after x days

[tex]50-3.50x>100-6x[/tex]

Answer:

I think 8n >_ 60

Im not sure but thats what i put

Step-by-step explanation:

The inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.

Inequality is an expression or statement of an order relationship, which involves the use of inequality signs, variables, numbers and/or algebraic expressions.

Thus:

n = number of brushes in a pack

The teacher must buy 60 brushes and above.

Thus:

8n ≥ 60 will represent the minimum number of brushes for the class.

Therefore, the inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.
