Answer:

X= -13

Step-by-step explanation:

Your first goal is to get all the X’s to one side of the equation.

So:

3x - 5 = 9x + 8 - 5x

+5x +5x

8x - 5 = 9x + 8

-9x -9x

-1x - 5 = 8

Now that you have all the X variables simplified and on one side, you make sure all of you constant terms are on the other side.

-1x - 5 = 8

+5 +5

-1x = 13

Because you can’t have a negative X, you divide the entire equation by -1.

-1x = 13

-1

x = -13

Dividing by -1 will give you the inverse of the equation which is positive one x equals negative thirteen.

Answer:

x=5, x=-1

Step-by-step explanation:

Since both equations are equal to y, we can set them equal to each other

y = -x + 7 and y = 0.5(x - 3)2

-x + 7 = 0.5(x - 3)^2

Distribute the right hand side by Foiling

-x+7 =.5 ( x^2 -3x-3x+9)

Combine like terms

-x+7 = .5( x^2 -6x+9)

Distribute the .5

-x+7 = .5x^2 -3x+4.5

Add x to each side

-x+x+7 = .5x^2 -3x+x+4.5

7 =  .5x^2 -2x+4.5

Subtract 7 from each side

7 -7= .5x^2 -2x+4.5-7

0 = .5x^2 -2x-2.5

Multiply by 2 to clear the decimals

0 = x^2 -4x -5

Factor

0 = (x-5) (x+1)

Using the zero product property

x-5=0  x+1 =0

x=5, x=-1

I can answer your question if you could type in English plz

Answer:

68

Step-by-step explanation:

48+2+20

So, tangents are equal to each other when they come to a point. So, all you have to do is set 3x+10 and 7x-6 equal to each other. 3x+10=7x-6 subtract 3x from both sides 10=4x-6 and now add 6 to both sides to get 16=4x, divide by 4 on each side and x=4.

Answer:

[tex]y=(2/3)x[/tex]

The graph in the attached figure

Step-by-step explanation:

Let

x-----> the number of pints

y----> the number of servings

For x=3 pints, y=2 servings

This is a proportional variation

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

so

The linear equation is equal to

[tex]y=(2/3)x[/tex]

The graph in the attached figure

Answer:

The graph is attached below

Step-by-step explanation:

A refreshment stand makes 2 large servings of frozen yogurt from 3 pints.

Equation of the line is y=mx+b

where m is the slope and b is the y intercept

2 large serving from 3 pints

So the servings over pints is 2/3

[tex]slope = \frac{2}{3}[/tex]

The y intercept is (0,0). the value of b is 0

We got m=2/3 and b=0

The equation of the line is

[tex]y=\frac{2}{3}x+0[/tex]

[tex]y=\frac{2}{3}x[/tex]

Now make a table. Assume some number for x  and find out y

x            y

0            0

3             2

6             4

Now make a graph using points (0,0) (3,2) and (6,4)

To solve the inequality -1/2 p < -16, multiply all parts of the inequality by '-2' and reverse the inequality sign, yielding 'p' > 32. Therefore, any real number greater than 32 will satisfy the original inequality.

For solving the inequality -1/2 p < -16, you want to find the value of 'p' where the inequality holds true. To do that, you should remove the fraction from the inequality. You can do this by multiplying every part of the inequality by '-2', however, remember that when you multiply or divide by negative numbers in an inequality, the direction of the inequality sign changes.

So, (-1/2 p) * -2 becomes 'p' and -16 * -2 becomes 32, reversing the inequality sign results in 'p' > 32.

In terms of a solution set, this implies that any real number greater than 32 will satisfy the original inequality -1/2 p < -16.

Answer:

see explanation

Step-by-step explanation:

Given

x² + 10x + 14 = - 7 ( subtract 14 from both sides )

x² + 10x = - 21

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(5)x + 25 = - 21 + 25

(x + 5)² = 4 ( take the square root of both sides )

x + 5 = ± 2 ( subtract 5 from both sides )

x = - 5 ± 2

x = - 5 - 2 = - 7, or x = - 5 + 2 = - 3

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

The equation can also be solved by factoring

x² + 10x + 14 = - 7 ( add 7 to both sides )

x² + 10x + 21 = 0 ← in standard form

(x + 7)(x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x + 3 = 0 ⇒ x = - 3

Answer:

Perimeter of Rhombus = 104 inches  

Step-by-step explanation:

To find the Perimeter of Rhombus we use the formula

Perimeter of rhombus = 4*Length

We need to find the length of rhombus.

if the rhombus has diagonals, it makes four right angled triangles (as shown in figure).

Since 4 triangles are made so, each side of triangle is half of the length of the diagonal.

In our case: Length of diagonals are: 20 and 48

but the Length of sides of triangle will be: 10 and 24

To find the side of rhombus, we can use Pythgoras theorem since the triangles are right angled.

c² = a²+b²

c² = (10)² + (24)²

c² = 100 + 576

c² = 676

√c²= √676

c = 26

So, the length of side of rhombus is 26 inches

Perimeter = 4*length

                = 4*26

                = 104 inches

Perimeter of Rhombus = 104 inches.  

The length of the perimeter of the rhombus is 104 inches.

To find the perimeter of a rhombus with given diagonal lengths of 20 inches and 48 inches, we can use the properties of rhombuses:

Step 1. Relationship between diagonals in a rhombus:

The diagonals in a rhombus cut each other at right angles. Let the diagonal lengths be [tex]\( d_1 \)[/tex] and [tex]\( d_2 \)[/tex].

Step 2. Formula to find side length from diagonals:

The following formula can be used to find the side length ( s ) of a rhombus:

[tex]\[ s = \frac{1}{2} \sqrt{d_1^2 + d_2^2} \][/tex]

where [tex]\( d_1 = 20 \)[/tex] inches and [tex]\( d_2 = 48 \)[/tex] inches.

Step 3. Calculate the side length:

[tex]\[ s = \frac{1}{2} \sqrt{20^2 + 48^2} \][/tex]

[tex]\[ s = \frac{1}{2} \sqrt{400 + 2304} \][/tex]

[tex]\[ s = \frac{1}{2} \sqrt{2704} \][/tex]

[tex]\[ s = \frac{1}{2} \times 52 = 26 \text{ inches} \][/tex]

Step 4. Calculate the perimeter:

The perimeter ( P ) of a rhombus, with all sides equal, is determined by:

[tex]\[ P = 4 \times s = 4 \times 26 = 104 \text{ inches} \][/tex]

Therefore, the length of the perimeter of the rhombus is 104 inches.

14×3×3=126. So 126 is your answer.

Answer:

14*4*3         168

Step-by-step explanat

Answer:

The base = 5, The legs are 6 each.

Step-by-step explanation:

Let the Base=x, Let the legs = (2x-4)

Perimeter = sum of all the sides = x + (2x-4) + (2x-4) = 5x-8 when you combine the like terms.

You know that the Perimeter = 17 cm. So, 17=5x-8.

Now you can solve for x. Once you do that, you can put your value of x into the leg equations.

17=5x-8

17+8=5x-8+8

25=5x

x=5

The Base is x=5 cm long, The Legs are each 2x-4=2(5)-4=10-4=6 cm long.

The Perimeter is x + (2x-4) + (2x-4) = 5 + 6 + 6 = 17.

Answer:

x= 25, y = 19

Step-by-step explanation:

Solve the following system:

{x = y + 6 | (equation 1)

9 y - 8 x = -29 | (equation 2)

Express the system in standard form:

{x - y = 6 | (equation 1)

-(8 x) + 9 y = -29 | (equation 2)

Swap equation 1 with equation 2:

{-(8 x) + 9 y = -29 | (equation 1)

x - y = 6 | (equation 2)

Add 1/8 × (equation 1) to equation 2:

{-(8 x) + 9 y = -29 | (equation 1)

0 x+y/8 = 19/8 | (equation 2)

Multiply equation 2 by 8:

{-(8 x) + 9 y = -29 | (equation 1)

0 x+y = 19 | (equation 2)

Subtract 9 × (equation 2) from equation 1:

{-(8 x)+0 y = -200 | (equation 1)

0 x+y = 19 | (equation 2)

Divide equation 1 by -8:

{x+0 y = 25 | (equation 1)

0 x+y = 19 | (equation 2)

Collect results:

Answer:  {x = 25 , y = 19

Answer: X= -29, Y= -267 over 10

Step-by-step explanation:

X= -29, substitute the value of X into the equation 6+y-8(-29)+9y an then solve for Y...

Step-by-step explanation:

Using the rules of exponents

• [tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]

• [tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex]

Hence

[tex]7^{-5/6-7/6}[/tex] = [tex]7^{-\frac{12}{6} }[/tex] = [tex]7^{-2}[/tex], then

[tex]7^{-2}[/tex] = [tex]\frac{1}{7^{2} }[/tex] = [tex]\frac{1}{49}[/tex] → C

ANSWER

C. 1/49

EXPLANATION

The given expression is

[tex] {7}^{ - \frac{5}{6} } \times {7}^{ - \frac{7}{6} } [/tex]

Recall that:

[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]

We apply this product rule of exponents to get:

[tex] {7}^{ - \frac{5}{6} } \times {7}^{ - \frac{7}{6} } = {7}^{ - \frac{5}{6} + - \frac{7}{6} } [/tex]

This implies that:

[tex] {7}^{ - \frac{5}{6} } \times {7}^{ - \frac{7}{6} } = {7}^{ - \frac{12}{6} } [/tex]

[tex]{7}^{ - \frac{5}{6} } \times {7}^{ - \frac{7}{6} } = {7}^{ - 2} [/tex]

Recall again that:

[tex] {a}^{ - m} = \frac{1}{ {a}^{m} } [/tex]

We apply this rule to get:

[tex]{7}^{ - \frac{5}{6} } \times {7}^{ - \frac{7}{6} } = \frac{1}{ {7}^{2} } [/tex]

This simplifies to:

[tex]{7}^{ - \frac{5}{6} } \times {7}^{ - \frac{7}{6} } = \frac{1}{49} [/tex]

Answer:

20% of the number 40 is 8

20% x 40=800 divide 100 =8

To calculate Nick's monthly mortgage payment, determine the loan amount, convert the interest rate to a monthly rate, and use the formula for fixed mortgage payments. The monthly payment for Nick's mortgage is $467.72.

The monthly payment can be calculated using the loan amount, interest rate, and loan term.

Calculate the loan amount: $145,500 × 75% = $109,125.

Convert the annual interest rate to a monthly rate: 3.15% ÷ 12 = 0.2625%.

Plug the values into the formula for fixed mortgage payments: [tex]$109,125*\frac{0.002625*(1+0.002625)^{30*12}}{(1+0.002625)^{30*12}-1}[/tex]

The monthly payment for Nick's mortgage is $467.72.

The correct answer is option C. The monthly payment for Nick's mortgage is $467.72.

First, we calculate the mortgage amount, which is 75% of the purchase price:

[tex]\[ \text{Mortgage amount} = \frac{75}{100} \times \$145,500 = \$109,125. \][/tex]

Next, we convert the annual interest rate to a monthly interest rate:

[tex]\[ \text{Monthly interest rate} = \frac{3.15\%}{12} = \frac{0.0315}{12} \approx 0.002625. \][/tex]

Now, we use the formula for the monthly payment (M) on a fixed-rate mortgage, which is given by:

[tex]\[ M = P \times \frac{r(1 + r)^n}{(1 + r)^n - 1}, \][/tex]

where P is the principal loan amount, r is the monthly interest rate, and n is the number of payments (30 years times 12 months per year).

So, we have:

[tex]\[ P = \$109,125, \][/tex]

[tex]\[ r = 0.002625, \][/tex]

[tex]\[ n = 30 \times 12 = 360. \][/tex]

Plugging these values into the formula gives us:

[tex]\[ M = \$109,125 \times \frac{0.002625(1 + 0.002625)^{360}}{(1 + 0.002625)^{360} - 1}. \][/tex]

Calculating this expression yields:

[tex]\[ M \approx \$467.72. \][/tex]

The complete question is:

Nick's new home had a purchase price of $145,500. He got a 30-year fixed mortgage for 75% of the purchase price. The interest rate on the loan is 3.15%. What is his monthly payment?

Answer:

Both Scott and Tara have responded correctly.

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

A=(1/2)[b1+b2]h

we have

b1=16 cm

b2=24 cm

h=8 cm -----> Note The height is 8 cm instead of 18 cm

substitute

A=(1/2)[16+24](8)

A=160 cm²

Verify Scott 's work

Note Scott wrote A = (1/2)(24 + 16)(8) instead of A = 2(24 + 16)(8)

Remember that the Commutative Property establishes "The order of the addends does not alter its result"

so

(24+16)=(16+24)

A = (1/2)(24 + 16)(8)=160 cm²

Verify Tara's work

Note Tara wrote A = (1/2)(16+24)(8) instead of A = (16 + 24)(8)

A = (1/2)(16+24)(8)=160 cm²
