y=2/5x-3

Step-by-step explanation:

y=2/5x+2-5

y=2/5x-3

The value of f(7) is 35

Solution:

Given function is:

f(x) = 5x

We have to find the value of f(7)

The value of f(7) can be found by substituting x = 7 in given function

Plug in x = 7 in function

[tex]f(x) = 5x\\\\f(7) = 5(7)\\\\f(7) = 5 \times 7\\\\f(7) = 35[/tex]

Thus the value of f(7) is 35

To find f(7), substitute x = 7 into the function f(x) = 5x. The value of f(7) is 35.

To find the value of f(7) if f(x) = 5x, substitute x = 7 into the function. We get:

Therefore, the value of f(7) is 35.

Answer:

lenght = 13 inches

width = 7 inches

Step-by-step explanation:

p= 2(l+b)

let lenght be x

width be y

so x=y+6

40 = 2(y+6 + y)

40= 2( 2y+6 )

20= 2y +6

2y = 20-6

2y=14

y=7

x=7+6=13

so lenght is 13 inches

width is 7 inches

The problem is about finding the length and width of a rectangle given its perimeter and their relationship. Solve it by forming an equation from the given information and solving for 'x'. The resulting dimensions are a width of 7 inches and length of 13 inches.

The question given is a problem in algebra and pertains to the dimension of a rectangle. To solve it, let's assume the width of the rectangle to be 'x'. As per the information given, the length can be written as 'x+6'. The formula for the perimeter of a rectangle is 2*(Length + Width).

In this problem, we have perimeter = 40 inches. By substituting the values of length and width into the formula, we get: 2*(x + (x+6)) = 40.

By simplifying, you find that 2*(2x+6) = 40, which reduces to 4x+12 = 40. If you subtract 12 from each side, you get: 4x = 28. Finally, dividing each side by 4 you find the width 'x' equals 7.

Substituting x=7 in length equation: length = 7+6 = 13. So, the dimensions of the rectangle are width = 7 inches, and length = 13 inches.

Answer:

Dave drove 168 miles during the 2nd part of the trip

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Speed of Dave for part of the trip = 55 mph

Speed of Dave the rest of the trip = 60 mph

Total time of the round trip = 4 hours 12 minutes

Total distance of the trip = 245 miles

2. How far did Dave drive during the 2nd part of his trip?

Let's recall that the formula of speed is:

Speed = Distance/Time, therefore Distance = Speed * Time

x = Time of part of the trip

4 hours 12 minutes - x = Time of the rest of the trip

4.2 hours - x = Time of the rest of the trip

Now, we can write solve for x, this way:

55 * x + 60 (4.2 - x) = 245

55x + 252 - 60x = 245

-5x = 245 - 252

-5x = -7

x = -7/-5 = 7/5 = 1.4 ⇒ 4.2 - x = 2.8

1st part of the trip = 55 * 1.4 = 77 miles

2nd part of the trip = 2.8 * 60 = 168 miles

Dave drove 168 miles during the 2nd part of the trip and 77 miles during the 1st part

Answer:Its D, just took the test.

Step-by-step explanation:

The US Treasury Bonds is the best choice for Denzel's investment based on his preference for moderate risk, trust in government-issued investments, and a desire for a return within a year.

Based on Denzel's investment preferences, the ideal choice for him would likely be D. US Treasury bonds. US Treasury bonds are direct obligations of the federal government, making them quite secure because they carry the full faith and credit of the U.S. government. Also, given that these bonds often provide moderate returns and can be purchased with various maturity dates (including one-year bonds), they line up with Denzel's desire to see a return on his investment in a year and his reluctance to lock his money up for long periods without realizing gains.

It's worth noting that, while the other options listed might also be suitable investments for different scenarios, they do not align as well with Denzel's specific risk tolerance, investment timeline, and trust in government-issued investments.

72 Wrong, so find how many are right with 135 total

Step-by-step explanation:

It's similar to saying if she answered half and this continued how many would she have answered after answering a bigger number, you would say half.

so she answered 8/15 incorrectly a a smaller number, so she will answer that ratio with a bigger number.  If it helps 8/15 is about 53%. just like 1/2 is half.  So to find half you would multiply something by 1/2 and int he same way you multiply something by 8/15 to get that proportion of it.

so 135, if you take this 53%, or simply multiply it by 8/15 you get your answer of 72.  So 72 wrong so al others are right, which you get with 135-72 = 63.

You could also do 135*(1-8/15) = 135 * 7/15.  if you ever want to find something NOT part of the proportion you do 1 - that proportion.

Step-by-step explanation:

For the similar triangles, the ratio of the length of the bottom side to the right side is the same:

  bottom/right = (x cm)/(6 cm) = (12 cm)/(10 cm)

  x cm = (6 cm)(12/10) = 7.2 cm

Technically, x = 7.2, not 7.2 cm.

Answer:

x=1 y= 7

x=2 y= 10

x=3 y= 13

Step-by-step explanation:

y=3x+4

y=3(1)+4

=7

y=3(2)+4

=-10

y=3(3)+4

=13

For this case we have the following equation:

[tex]y = 3x + 4[/tex]

We must find the value of the variable y when the variable x takes certain values.

For [tex]x = 1:[/tex]

[tex]y = 3 (1) +4\\y = 3 + 4\\y = 7[/tex]

For [tex]x = 2:[/tex]

[tex]y = 3 (2) +4\\y = 6 + 4\\y = 10[/tex]

For [tex]x = 3:[/tex]

[tex]y = 3 (3) +4\\y = 9 + 4\\y = 13[/tex]

Thus, the values of y are 7,10,13 respectively.

Answer:

[tex]y = 7\\y = 10\\y = 13[/tex]

In expanded form, 57,000 equals 50,000 + 7,000 therefore, number 60 and 4 are NOT one of the numbers that Kim wrote.

The expanded form of a number is the division of a number into place values, such as ones, tens, hundreds, thousands, ten thousand, and so on.

The number represented by the sum of each digit multiplied by its place value is known as its expanded form. When you write a number in expanded form, you write the value of each digit and then add them together to find the sum.

The number 1,24 has the following values, for example: it is in the thousands place, the value of one is written as 1,00. thus it is in the hundreds place, the value of 2 is written as 20.

Therefore,

Expanded Form of 57,000

57,000 =  50,000 + 7,000.

3. 16f - 9 = -2 + f            Subtract f on both sides

4. 15f - 9 = -2                  Add 9 on both sides

5. 15f = 7                 Divide both equations by 15

Step-by-step explanation:

Assuming you mean

Below is a graph of that one. The slope is 3/4 and the interception with the y axis is at y=-4. The equation is in its normal form y=ax+b with a=3/4 (slope) and b=-4 (y intercept), so no conversion needed.

You have to be careful on how you write these equations down. It might very well be that you meant:

[tex]y = \frac{3}{4x-4}[/tex] or [tex]y = \frac{3}{4x} - 4[/tex]
