Answer:

The ordered pair for the system of equations is (x,y) i.e (4,7)

Step-by-step explanation:

Ordered pair is the represented as (x,y) i.e value of x and value of y.

We are given system of equations:

2x+4y=36      eq(1)

6x+2y=38     eq(2)

and after solving above equations value of x is found to be 4.

We need to find the value of y.

We can find value of y by putting value of x in eq(1)

2x+4y=36

2(4)+4y =36

8+4y = 36

4y = 36-8

4y = 28

y = 7

So, value of y is 7

The ordered pair for the system of equations is (x,y) i.e (4,7)

Answer:

The ordered pair is: (4, 7)

Step-by-step explanation:

We have the following system of equations

[tex]2x+4y=36[/tex]

[tex]6x+2y=38[/tex]

To find the ordered pair that represents the solution to the system of equations we need the value of x and the value of y.

We already know that x = 4.

Then we substitute the value of x in any of the two system equations and solve for the variable y.

[tex]2(4)+4y=36\\\\8 + 4y=36\\\\4y=36-8\\\\4y=28\\\\y=\frac{28}{4}\\\\y=7[/tex]

The ordered pair is: (4, 7)

Answer:

Step-by-step explanation:

The area of a pentagon given the radius is

Area = (5/2)r^2 * sin(72º)

r = 7

Area = (5/2)*7^2 * sin(72)

Area = 122.5 * 0.95106

Area = 116.5

=============

r = 5

Area = (5/2) * 5^2 * sin(72)

Area = 59.4

Area of the shaded area = 116.5 - 59.4

Area of the shaded area = 57.1

The explicit formula for the sequence -9,-3,3,9,15​ is [tex]a_n[/tex] =-9+(n-1)6.

The correct option is (C).

The explicit formula for an arithmetic sequence is an = a + (n - 1)d, and any term of the sequence can be computed, without knowing the other terms of the sequence.

Given sequence:  -9,-3,3,9,15​

As, the given sequence is arithmetic sequence.

So, the difference between two consecutive term is same.

i.e., (-3)-(-9)= -6, 3-(-3)= 6, and so on.

Now, the nth term is = a+(n-1)d

as, a=-9

So, [tex]a_n[/tex]= -9+(n-1)6

          = -9+6n-6

          = 6n-15

Hence, [tex]a_n[/tex] =-9+(n-1)6.

√a / (√a - 2)

To rationalize the denominator, you need to multiply the fraction by the conjugate:

√a / (√a - 2) × (√a + 2) / (√a + 2)

√a (√a + 2) / ((√a - 2) (√a + 2))

Answer:

x >  560

Step-by-step explanation:

0.1x + 0.25(102 - x) < 17.10

simplify

0.1x + 25.5 - 0.25x < 17.10

subtract 25.5 from both sides

0.1x + 25.5 - 25.5 - 0.25x < 17.10 - 25.5

0.1x  - 0.25x < - 84

- 0.15x < - 84

divide both sides by - 0.15

x < -84/-0.15 = 560

When you divide or multiply by a negative, the sign changes

x >  560

Hope this helps!

Please mark as brainliest.

To solve the inequality 0.1x + 0.25(102 - x) < 17.10, distribute, combine like terms, and isolate x to find that the values for x that make the inequality true are x > 56.

To find the values of x that make the inequality 0.1x + 0.25(102 - x) < 17.10 true, we need to solve the inequality. First, we distribute 0.25 to get 0.1x + 25.5 - 0.25x < 17.10. Then, combining like terms gives -0.15x + 25.5 < 17.10. Next, we subtract 25.5 from both sides to get -0.15x < -8.4. Finally, dividing both sides by -0.15 gives x > 56.

Answer:

In order to evaluate the given expression 17(144) using the distributive property, Julia would rewrite the expression in friendlier numbers that is:

(10+7)(100+40+4)

Step-by-step explanation:

We are given an expression 17(144) that we have to evaluate let us say without using the calculator.

Sometimes, it is easier to solve a complex problem in multiple steps as the problem gets distributed and the difficulty level lowers for multiple smaller sets.

Julia would rewrite the expression as:

(10+7)(100+40+4)

Then solve it using distribution method as follows:

10(100+40+4)+7(100+40+4)

1000+400+40+700+280+28

= 2448

Answer:

Step-by-step explanation:

Find the degree of each monomial term of the polynomial. The highest degree is the answer.

deg(3x^4)=4

deg(-4x^3y)=3+1=4

deg(6x^2y^2)=2+2=4

deg(-8x^2y^3)=2+3=5

deg(-7y^4)=4

deg(2)=0

The highest degree there is 5 so that is the degree of the polynomial.

The degree of a polynomial is the highest power of any variable in that polynomial. For the polynomial 3x⁴-4x³y+6x²y²-8x²y³-7y⁴+2, because the highest power is 4, the degree of the polynomial is 4.

The highest exponent of the variable in a polynomial determines its degree. In the provided polynomial, 3x⁴-4x³y+6x²y²-8x²y³-7y⁴+2, the degree of this polynomial is 4 because the highest power of the variable is 4. which can be seen in the terms 3x⁴ and -7y⁴.

It's important to note that while determining the degree of a polynomial, we consider the power (or degree) of individual terms and not their combined power. For example, in the term -4x³y, x has a degree of 3 and y has a degree of 1. The degree of -4x³y will still just be 3 (and not 4) as we only consider the highest degree within that term.

The values are 9 and 8

Step-by-step explanation:

Let the first number be x

Let the second number be y

The sum of x and y is x+y=17

The difference of x and y  is x-y=1

x+y=17  (this is equation 1)

x-y=1     (this is equation 2)

Now we will add equation 1 and equation 2.

x+y = 17

x-y = 1

______

2x   =18

x= 18/2

x= 9

Now put the value of x in equation 1.

x+y = 17

9+y = 17

y = 17-9

y = 8

8^x= 64

8²= 64

In logarithmic form,

log(base 8) 64= 2

The equation 8ˣ=64 in logarithmic form is written as log8(64) = x, where x is the exponent to which the base 8 is raised to obtain 64.

The equation 8ˣ=64 in logarithmic form, you have to understand the relationship between exponentials and logarithms. The logarithmic form of the equation is logb(a) = c, which means b to the power of c equals a. Given that 8 squared (8²) equals 64, you can express 8^x=64 as log8(64) = x, which is the logarithmic form of the given exponential equation.

Answer:

3,578

Step-by-step explanation:

Add the two values together.  If the bridge is 1,595 feet long, and if each cable holding that is 1,983 feet longer than the length of the bridge then adding them together is the way to go.

1,595+1,983=3,578

To get the length of each cable, you add the length of the bridge (1,595 feet) to the extra length of each cable (1,983 feet), which results in 3,578 feet.

The problem is asking us to work with addition. The bridge is 1,595 feet long and each cable is 1,983 feet longer than the bridge. To find the length of each cable, we add the length of bridge and the extra length of the cable. That is, we add 1,595 feet (length of bridge) to 1,983 feet (extra length of cable).

Answer:

596.8 feet^2

Step-by-step explanation:

The m < C  = 180 - 2*38.5 = 103 degrees ( because the triangle is isosceles).

Use the formula:  Area of a triangle = 1/2 ab sinC:

Area = 1/2 * 35 * 35 * sin 103

= 596.8 feet^2.

Answer:

4/5 divided by 8 = 4/(5*8) = 1/10

1: 8/10 divided by 8 = 8/(10*8) = 1/10

2: 8/5 divided by 4 = 8/(5*4) = 4/10

3: 5/4 multiplied by 8 = (5*8)/4 = 100/10

4: 4/5 multiplied by 8 = (4*8)/5 = 64/10

So the answer is 1.
