Jake is thinking of two numbers. Adding 3 times the first number and 4 times the second number gives a total of 1. Also, adding 2 times the first number and 3 times the second number gives 2.

The perfect square equation is f(x) = (x + 7/2)^2 - 9/4

The equation of the function is given as

f(x) = x^2 + 7x + 10

Rewrite the equation as

x^2 + 7x + 10 = 0

Subtract 10 from both sides of the equation

So, we have

x^2 + 7x = -10

-----------------------------------------------------------------------

Take the coefficient of x

k = 7

Divide by 2

k/2 = 7/2

Square both sides

(k/2) = 49/4

-----------------------------------------------------------------------

Add 49/4 to both sides of the equation

So, we have

x^2 + 7x + 49/4 = -10 + 49/4

Express as a perfect square

So, we have

(x + 7/2)^2 = -10 + 49/4

Evaluate the sum

So, we have

(x + 7/2)^2 = 9/4

This gives

(x + 7/2)^2 - 9/4 = 0

So, we have

f(x) = (x + 7/2)^2 - 9/4

Hence, the perfect square equation is f(x) = (x + 7/2)^2 - 9/4

The solution of the given equation 5-4t = 12 is at t = -7/4.

According to the given question.

We have a linear equation in one variable.

5 - 4t = 12

As we know that, linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, th esolution for the given equation 5 - 4t = 12 is given by

5 - 4t = 12

⇒ -4t = 12 - 5      (subtracting 5 from both the sides)

⇒ -4t = 7

⇒ -t = 7/4          (dividing both the sides by 4)

⇒ t = -7/4

The perimeter of right isosceles ΔABC with midsegment DE is 16 + 8√2.

If right isosceles ΔABC has hypotenuse length h, then the two other sides are congruent.

side a = side b

Using Pythagorean theorem, c^2 = a^2 + b^2

h^2 = a^2 + b^2      a = b

h^2 = 2a^2

a = h/√2

If DE is a midsegment not parallel to the hypotenuse, then it is a segment that connects the midpoints of one side of a triangle and the hypotenuse. See photo for reference.

ΔABC and ΔADE are similar triangles.

a : b : h = a/2 : 4 : h/2

If a/2 = a/2, then b/2 = 4.

b/2 = 4

b = 8

If a = b, then a = 8.

If a = h/√2, then

8 = h/√2

h = 8√2

Solving for the perimeter,

P = a + b + h

P = 8 + 8 + 8√2

14.   [tex]-3(x+2)+4[/tex]

12.   [tex]4[/tex]

15.   [tex]0[/tex]

Step-by-step explanation:

Question 14

To find the function in terms of "x+2", simply replace "x" in the original equation with "x+2":

[tex]f(x+2)=-3(x+2)+4[/tex]

Now simplify by distributing the 3:

[tex]f(x+2)=-3x-6+4[/tex]

Finish by adding the constants:

[tex]f(x+2)=-3x-2[/tex]

Question 12

This one follows the same concept! Replace "x" in the original equation with 1/2:

[tex]F(\frac{1}{2})=-2(\frac{1}{2} )+5[/tex]

Simplify:

[tex]f(\frac{1}{2})=-1+5\\f(\frac{1}{2})=4[/tex]

Question 15

For this question, it looks like you are given a set of coordinate pairs in the function. You are asked to find "f(4)". Essentially, you are being asked to find the value of y given 4 as the value of x.

The given coordinate pair (4,0) has 4 as the x value, so the y value when x=4 is 0!

The missing 2nd term of the given arithmetic sequence 25, _, 53,...(a₂ = 39).

The difference between the two different numerical orders is a fixed number in Arithmetic Progression (AP). Another name for it is Arithmetic Sequence.

We'd come along through a few specific words in AP that were labeled as:

The AP can also be understood in terms of common differences, as shown below.

Now, for the given AP;   25, _, 53....

Let the initial term be 'a₁' = 25

Let the second term be 'a₂' = ?

Let the third term be 'a₃' = 53.

The AP must have the same common difference. So,

d =  a₂ - a₁ or d = a₃ - a₂

Equating the common difference to find the 2nd missing term.

a₃ - a₂ = a₂ - a₁

Substitute the given values;

53 - a₂ = a₂ - 25

Bring the variable part on one side.

2a₂ = 53 + 25

a₂ = 78/2

a₂ = 39

Therefore, the 2nd missing value of an AP is found to be 39.

The radius that can he use for the garden is H. 8

A circle's outside boundary is called the circumference and can be measured, or calculated, by using

Circumference = 2πr

where r is the radius of circle.

Now it is given that,

Length of fence = 50 feet

⇒ Circumference of  vegetable garden = 50 feet

Since, Circumference = 2πr

⇒ 2πr = 50

⇒ r = 50/2π

⇒ r = 50/6.28

⇒ r = 7.96

Answer:

Step-by-step explanation:

7/8 is 0.875 so it makes it 87.5%

The percentage form of the given number is:

1.15 as a percent is 115%

7/8 as a percent is 187.5%

To convert a decimal to a percent,

we need to multiply it by 100.

So for 1.15,

Multiply it by 100 to get 115%.

To convert a mixed number to a percent,

We have to convert it to an improper fraction first.

To do that, we multiply the denominator by the whole number and add the numerator.

Then we put that answer over the original denominator.

For 7/8, the improper fraction would be,

(8 x 1) + 7 = 15/8.

To convert this to a percentage,

We need to divide the numerator by the denominator and multiply by 100.

So 15/8 as a decimal is 1.875, and when we multiply that by 100 we get 187.5%.

The simplified expression for (10-22 / 8-17) is 4/3 .

The given expression is,

( 10-22 / 8-17 )

First we need to solve the numerator which is (10-22) and on simplifying the numerator we can write,

Numerator = ( 10 - 22 ) = -12                         equation 1

Similarly, now we can proceed to solve the denominator which is (8 - 17) and on simplifying the denominator we write,

Denominator  = (8 - 17) = -9                       equation 2

Now we can substitute the value of numerator and the denominator from equation 1 and equation 2 in the given expression ( 10-22 / 8-17 ) as,

(Numerator / Denominator) = (10-22 / 8-17) = ((-12)/(-9)) = 4/3

What is the constant of proportion?

A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.

Solving for the value of y

let k be the constant of proportion

When a quantity varies directly with others, then we have a relation, y = kx      —-- 1

Now, find k for given x = 3 / 4 and y = 5 / 3, we need to put these values in equation 1, i.e.

5 / 3 = k(3 / 4)

k = (5 × 4) / 9

k = 20 / 9

Further calculate x for given y = ½ and constant of proportion = 20/9i.e.

½ = (20 / 9)x

x = 9 / 40

Hence, the required value of x is 9 / 40.
