Step-by-step explanation:

[tex]f(x)=4x+8\\y=4x+8\\x=4y+8\\\\[/tex]

Proceed the inverse. Swap the x and y.

[tex]x-8=4y\\\frac{x}{4}-\frac{8}{4}=y\\y=h(x)\\h(x)=\frac{x}{4}-2\\h(x)=\frac{1}{4}x-2[/tex]

So the answer is first one.

Decimal point in product is the sum of the decimal points in the numbers which we are multiplying.

For ex :

2.6 × 6.7 = 17.42

1    +    1  =  2

For, 1.7 × 2.5  the sum of decimal in each number is 1 and 1 .

So, decimal in product is at 2 i.e 4.25 .

For, 3.62 × 1.7 the sum of decimal in each number is 2 and 1.

Decimal in product is at 2 + 1 = 3 i.e 6.154 .

Therefore, solution is 1.7 × 2.5 = 4.25 and 3.62 × 1.7 = 6.154 .

Hence, this is the required solution.

Answer: X = 5

Step-by-step explanation: Since a square has all equal sides, and area is just length times width, the other side has to be five. If you REALLY feel the need to check my work just do 5x5.

Answer:

29

Step-by-step explanation:

Start with -39. We need to do inverse operations to figure out the solution. -39 divided by -3 is 13, and 13 plus 16 is 29.

Answer:

29

Step-by-step explanation:

-39=-3(n-16)

13=n-16

29=n

Answer:

Step-by-step explanation:

Let the width of the rectangle be 'w'

According to the question length of the rectangle (l) is 4 more than 3 times it's width;

[tex] \longrightarrow [/tex] l = 3w + 4

Perimeter of rectangle = 152

Formula of perimeter of rectangle = 2(Length + Width)

So,

[tex]\rm \implies 2(Length + Width) = 152 \\ \\ \rm \implies 2(3w + 4+ w) = 152 \\ \\ \rm \implies 2(4w + 4) = 152 \\ \\ \rm \implies 2 \times 4(w + 1) = 152 \\ \\ \rm \implies 8(w + 1) = 152 \\ \\ \rm \implies w + 1 = \dfrac{152}{8} \\ \\ \rm \implies w + 1 = 19 \\ \\ \rm \implies w = 19 - 1 \\ \\ \rm \implies w = 18[/tex]

[tex] \therefore [/tex] Width of the rectangle (w) = 18

Length of rectangle (l) = 3 × 18 + 4 = 58

Step-by-step explanation:

Given :

Total pounds of potatoes, T = 62,049.

On Monday a farmer sold 25,196 pounds of potatoes on Tuesday he sold 18,023 pounds.

To Find :

How many pounds he sold in Wednesday to end the stock.

Solution :

Potatoes sold in Wednesday = Total - Potatoes sold in Monday - Potatoes sold in Tuesday

= 62049 - 25196 - 18023 pounds

= 18830  pounds

Hence, this is the required solution.

Answer:

7y+13=5y-3

7y=5y-16

2y=-16

Y=-8

Step-by-step explanation:

Answer: yes

Step-by-step explanation:

You collect like times together.

7 y + 13 = 5 y - 3

7 y - 5 y = - 3 - 13

2 y = - 16

2 y / 2 = - 16 / 2

y = - 8

Directions

You have to do this by following directions.

1, Go one circle to your right. Make it the top circle.

2, Drop a perpendicular from the circle you've just been directed to.

3. Draw until you hit the center of the circle below the circle you started your line from. You should get a square.

Find the area of the square.

Each side of the square is 2 feet. You get that because the side of the square = 2 radii -- one radii from the two circles in the center.

Area Square = s^2

Area Square = 2 * 2

Area Square = 4

Find the are of the circles

The 4 central circles that are touching (2 to the left and 2 to the right)  are each are 1/4 of a full circle. 4 * 1/4 circle Area = 1 full circle.

Area = pi * r^2 = 3.14 * 1^2 = 3.14

Find the area of the star

Area of the star = area of square - area of circle.

Area of the star = 4 - 3.14

Area of the star = .86 sqr feet

Answer:

6+1.25t

Step-by-step explanation:

W(in the 1st month)=6+1.25

W(in the 2nd month)=6+1.25+1.25

W(in the 3rd month)=6+1.25+1.25+1.25

W(in the t months)=6+t(1.25)

Answer:

y = 3x + 7

Step-by-step explanation:

Using the formula y = mx + b we can create this equation.

m = slope

b = y -intercept

based on the information provided I know that

Slope = 3

and

y-intercept = 7

Substitute:

y = mx + b

y = 3x + 7

y = 3x + 7 is the equation when the slope is 3 and the y intercept is 7.

Let us use the slope-intercept form for this, with m as the slope and b as a constant.

y = mx + b

7 = 3(0) + b  [since the y-int is 7, the x value will be zero]

b = 7

y = 3x + 7

Answer:

[tex]\frac{6+\sqrt{27} }{4-\sqrt{3} } = \frac{r+s\sqrt{3} }{13} \\We\ may\ multiply\ the\ numerator\ and\ denominator\ with\ (4+\sqrt{3} ).\\Hence,\\\frac{(6+\sqrt{27})(4+\sqrt{3}) }{13} = \frac{r+s\sqrt{3} }{13} \\Hence,\\24+6\sqrt{3} +4\sqrt{27} +9= r+s\sqrt{3}\\24+6\sqrt{3} +4*3\sqrt{3} } +9= r+s\sqrt{3}\\24+6\sqrt{3} +12\sqrt{3}+9 = r+s\sqrt{3}\\33+18\sqrt{3} = r+s\sqrt{3}\\Hence,\\r=33, s=18[/tex]

Based on the HL congruence rule, the value of x, is calculated as:

x = 2.

Both triangles that share the same side and have corresponding angle 90 degrees and a pair of corresponding congruent hypotenuse are congruent  to each other based on the HL congruence theorem.

This means that:

17x - 3 = 9x + 13

Solve for the value of x:

17x - 9x = 3 + 13

8x = 16

Divide both sides by 8:

8x/8 = 16/8

x = 2

The value of x is: 2.
