if f =28 when a = 7 find f when a is 10 (direct proportion) ​

Answers

Answer 1

Answer:

f=40

Step-by-step explanation:

f=28, a=7

[tex]f \infty a \\ f = ka \\28 = k(7) \\ 28 = 7k \\ \frac{28}{7} = \frac{7k}{7} \\ 4 = k \\ k = 4 \\ f = 4a \\ a = 10 \\ f = 4(10) \\ f = 40[/tex]

Hope that this is helpful.

Have a nice day.

Answer: 9^2 or can also be read as 9 squared.The base itself is worth 9 but when you include the exponent its 81.When your solving exponents your multiplying the base by itself as many times as the exponent reads.In this case its 9x9 (2 times). The value of the base is 9 (just wanted to explain the other stuff just in case you didn't know)

Write an equation for a function that has a slope of 3 and that passes through the point (8, 14).

Answers

Answer:

[tex]f(x)=3x-10[/tex]

Step-by-step explanation:

Recall point-slope form: Given a point [tex](x_{1}, y_{1})[/tex] and the slope [tex]m[/tex], the equation for the line is [tex]y-y_{1}=m(x-x_{1})[/tex].

We can plug in for our point and slope!

The equation for the line is [tex]y-14=3(x-8)[/tex].

Distributing the right side gives [tex]y-14=3x-24[/tex].

Adding [tex]14[/tex] to both sides gives [tex]y=3x-10[/tex].

So, the function is [tex]\boxed{f(x)=3x-10}[/tex] and we're done!

Step-by-step explanation:

Both give you the same answer, thus the arrangement of the INTEGERS does not matter.

Note that I mentioned integers since this is not possible for natural numbers alone. They are not closed under subtraction. Here you -1 and 5 both of  which are integers, their SUM  give you an integer as well.

Mia is solving the equation x2 – 12x = 1. Which value must be added to both sides of the equation to make the left side a perfect-square trinomial?


9


-9


36


8

Answers

The value to be added to both sides of the equation to make the left side a perfect square trinomial is; -36.

To make the equation x2 – 12x = 1 look similar to the completing the square kind of expression where the left hand side of the equation becomes a perfect square, we must do the following;

First, the completing the square method usually takes the form;

+ bx = (x + b/2)² + c

In this scenario, the term (x² - 12x) can be rewritten as; (x - 6)² - 36.

This so because the expansion of (x - 6)² becomes;

x² - 12x + 36.

Therefore, there's a need to subtract 36 from both sides of the equation so that the equation x2 – 12x = 1 is retained.

Therefore, the value to be added to both sides of the equation to make the left side a perfect square trinomial is; -36.

__% of 4 is 7

Please help

Answers

Answer:

175%

Step-by-step explanation:

1. To find how much a percent of a number is, we'd just have to multiply the percent by the number. However, in this case, we're missing the percentage.

2. To find that percentage, we can write an equation of [tex]\frac{x}{100} * 4 = 7[/tex] because "of 4" means to multiply by 4, and "is 7" means that the product is 7.

3. Now, let's solve our equation.

[tex]\frac{x}{100} * 4 = 7[/tex]

Step 1: Simplify both sides of the equation.

[tex]\frac{4}{100}x = 7[/tex] [tex]\frac{1}{25}x=7[/tex]

Step 2: Multiply both sides by 25.

[tex]\frac{1}{25}x * 25 = 7 * 25[/tex] [tex]x = 175[/tex]

Step 3: Check to see if solution is correct.

[tex]\frac{175}{100} * 4 = 7[/tex] [tex]\frac{700}{100} = 7[/tex] [tex]7 = 7[/tex]

Therefore, the answer is 175%.

Answer:

Step-by-step explanation:

y+75 = 3y+5

75 - 5 = 3y - y

70 = 2y

y = 70/2

y = 35

3x+7 = 5x-35

7 + 35 = 5x - 3x

42 = 2x

x = 42/2

x = 21

check:

(3x+7) + (y+75) + (5x-35) + (3y+5) = 360

(3*21 + 7) + (35 + 75) + (5*21 - 35) + (3*35 + 5) = 360

(63+7) + (110) + (105-35) + (105+5) = 360
