what does this integral unit mean? ​

Answer:

A

Step-by-step explanation:

The equation of the given situation is required.

Slope intercept form [tex]y=-1.25x+25[/tex]

Standard form [tex]1.25x-y=25[/tex]

The total amount of money is $25.

Cost of one donut is $1.25

Let y be the amount of money left

x be the number of donuts bought.

So, the amount of money left after buying x donuts is

[tex]y=25-1.25x\\\Rightarrow y=-1.25x+25[/tex]

The standard form is [tex]1.25x-y=25[/tex]

Answer:

y = 5x + 5

Step-by-step explanation:

the slope to be parallel y = 5x + 7 must still be 5. To make the line pass through T, the given point, you plug (-2, -5) into the y= mx + b formula. This becomes( -5 )= 5 (-2) + B, and you solve for b. In this equation, b = 5.

Answer:

let the unknown angle be x

we know. sum of angles of a triangle is 180°

so,

130+20+x=180

150+x=180

x=180-150

x=30°

Answer:

The dimensions are 18m by 18m

Step-by-step explanation:

Since the problem says the floor is square, we know that all 4 sides are equal. The area for a square is one side squared. Since we do not have the actual length per side, we write the following formula: x^2= 324.

From there, we simply take the square root to figure out that one side is 18 meters. Once we know one side, we know all 4 because a square has equal sides. Therefore, the dimensions of the floor are 18m x 18m. I hope this helps!

Answer:

Perimeter = 25.6 cm

Explanation:

Answer:

w=-8.6 is your answer

-5w-43. is the simple version

Step-by-step explanation:

First distrubute the -7 and set equal to 0 so that we can move the w to the other side.

-7w-28+2w-15=0

-5w-43=0

add 43 to both sides so you can slove for w

-5w=43

divide both sides by -5 to isolate the w

w=-8.6

Answer: 186,000

Step-by-step explanation:

You round the 282 down so that it is an even thousand. <3

186,282 rounded to the nearest thousand is 186,000.

To round 186,282 to the nearest thousand, we look at the digit in the thousands place, which is '6'.

If the digit in the hundreds place is 5 or greater, we round up. If it is less than 5, we round down.

In this case, since the digit in the hundreds place is '8', which is greater than 5, we round up.

To round up, we increase the digit in the thousands place by 1 and replace all the digits to the right with zeros.

Therefore, rounding 186,282 to the nearest thousand gives us 187,000.

Answer:

50 people

Step-by-step explanation:

so to solve this we can use cross multiplying:

first we know that 20% = 10 people and 80% = x people (we put x because we don't know how many people)

then we set it up:

[tex]\frac{10}{20}[/tex] = [tex]\frac{x}{80}[/tex]

= 20x = 800

= x = 40

now it asks how many people were surveyed in total so we add the 10 + 40 = 50

50 people were surveyed

Answer:

y=1/2x+14

Step-by-step explanation:

If you mark (-8,10) in a graph and go up 1, over 2, then you will eventually get to (0,14).

You can also use the slope formula in reverse. 1/2=b-10/0-(-8)

1/2=b-10/8, then multiply both side by 8

4=b-10, add 10 to both sides

14=b

f(×)=-0,5x+2

8(×)= -5x+3

8×= -5x+3

8-5x+3

The nearest tenth as required, the point of intersection expressed as (0.2, 2.1).

To solve the system of equations,  to find the points where the two functions intersect, which means the x-values where f(x) equals g(x). Let's proceed with the solution:

f(x) = -0.5x + 2

g(x) = -5x + 3

Set f(x) equal to g(x):

-0.5x + 2 = -5x + 3

Now, let's solve for x:

Add 0.5x to both sides to eliminate the term with x on the left side:

2 = -4.5x + 3

Subtract 3 from both sides:

-1 = -4.5x

Now, divide by -4.5 to isolate x:

x = -1 / -4.5

x ≈ 0.2222

Now that we have the x-value of the point of intersection, let's find the corresponding y-value by plugging x back into either f(x) or g(x). Let's use f(x):

f(x) = -0.5x + 2

f(0.2222) = -0.5(0.2222) + 2

f(0.2222) ≈ 2.1111

So, the point of intersection is approximately (0.2222, 2.1111).

Answer:

x=9

Step-by-step explanation:

180 =120+5x+15

60=5x+15

45=5x

9=x

Answer:

1. f(–9) = -66 , g( 1 ) = 27  (Please double-check your given options, there must have been a typographical error for Option C for g( 1 ) = 29). g( 1 ) is supposed to be 27.

2. Option A: f(–9) = 25, g(–1) = 21

Step-by-step explanation:

1.Find the value of f(–9) and g(1) if f(x) = 8x + 6 and g(x) = 9x + 20x−2

f(x) = 8x + 6

f(–9) = 8(-9) + 6 = -66

g(x) = 9x + 20x − 2

g( 1 ) = 9( 1 ) + 20( 1 ) − 2 = 27

None of the given choices were correct (unless there's a typo error for Option C — it's supposed to be g( 1 ) = 27 instead of 29?) because the correct answers are: f(–9) = -66 and g( 1 ) = 27

2.  f(–9) and g(–1) if f(x) = –3x – 2 and g(x) = 3x³ – 24x

f(x) = –3x – 2

f(–9) = –3(–9) – 2 = 25

g(x) = 3x³ – 24x

g(–1) = 3(–1)³ – 24(–1) = 21

Therefore, the correct answer is Option A: f(–9) = 25, g(–1) = 21
