2x=8y=7
4x-2y=9

Answers

Assuming you mean 2x-8y=7, we can start by multiplying the first equation by -2 and adding it to the second (to cross out the x), resulting in -18y=-5. After that, we can divide both sides by -18, resulting in y=5/18. Next, plugging that into 4x-2y=9, we have 4x-10/18=9. Adding 10/18 to both sides, we get 4x=9+10/18. After that, we can divide both sides by 4, resulting in x=(9+10/18)/4=

∠E and ∠F are vertical angles with m∠E=8x+8 and m∠F=2x+38 . What is the value of x? Enter your answer in the box.

Answers

Set the two measures equal to each other. Subtract 2x from both sides and subtract 8 from both sides. Leaving you with 6x=30. Then divide 30/6 and you get X=5

Answer:

x = 5

Step-by-step explanation:

We need to remember that vertical angles are opposite to each other when two lines cross. The vertical angles that result from two lines crossing have the same measure.

In this problem we have angle E which measures 8x + 8 and angle F which measure 2x + 38.

Since they are vertical angles, we know that they have the same measure and therefore we can equal them both and solve for x:

[tex]8x+8=2x+38\\8x-2x=38-8\\6x=30\\x=5[/tex]

Therefore, x = 5 (and ∠E = ∠F = 48)

The measure of each interior angle of a regular polygon is 140 degrees, how many sides does the polygon have

Answers

using
[(n-2)180]÷n = 140
(n-2)180 = 140n
180n -360 = 140n
180n -140n = 360
40n = 360
n=360÷4 = 90 sides

Final answer:

The regular polygon with an interior angle of 140 degrees has 9 sides. This conclusion can be reached by using the formula for the interior angle of a polygon, which is (n-2)*180/n, where 'n' represents the number of sides.

Explanation:

The number of sides in a regular polygon can be determined using the formula for the interior angle of a polygon, which is (n-2)*180/n, where 'n' represents the number of sides. This formula comes from the fact that a polygon can be divided into (n-2) triangles, each of which has angles summing up to 180 degrees.

In this particular case, an interior angle of 140 degrees is given. So we will set up an equation: 140 = (n-2)*180/n. Solving for 'n', we get a value of 9.

Therefore, the regular polygon with an interior angle of 140 degrees has 9 sides.

Which expression can be used to change 75 kilometers per hours to meters per minute?

Answers

The fractions you use must be the correct conversion factors.

1 km = 1000 m, so you can have the fraction (1 km)/(1000 m) or the fraction (1000 m)//(1 km). You must choose the correct one for this problem.

1 hr = 60 min, so you can have the fraction (1 hr)/(60 min) or the fraction (60 min)/(1 hr). Again, you must choose the correct one for this problem.

The important thing is to choose the correct fraction from the choices.
How do you know which conversion fractions to use?
You look at the given units and the units you want.
You must pick the conversion fraction that will cancel out the units you DON'T want, leaving the units you want.

You have a speed in km/hr.
km is in the numerator. To cancel out km, you must pick the conversion fraction that km in the denominator.
hr is in the denominator. To cancel out hr, you must pick the fraction that has hr in the numerator.

[tex]75 \frac{km}{hr} \times \frac{1000~m}{1~km} \times \frac{1~hr}{60~min} [/tex]

Notice that km and km cancel out leaving m.
Also, hr and hr cancel out leaving min.

How is the distance formula like the pythagorean theorem explain?

Answers

The distance formula is simply a variation of the theorem. The method is the same with the Pythagorean however we are now dealing with 2 sets of points instead of 2 lengths.

In the distance formula, the lengths are derived from the (x1,y1)->(x2,y2) coordinate points and the formula simplified. We still square the difference of x’s and difference of y’s to get our two squares then square root the sum to give our length. While the Pythagorean theorem is directly the sum of the square of the other two sides.

Nevertheless, both formulas work on the same principle.

Answer:

Both formulas can be used to find the distance between two points on the coordinate plane. The vertical leg of the right triangle represents the difference in the y values of the two points. The horizontal leg of the right triangle represents the difference in the x values of the two points. The hypotenuse of the right triangle represents the distance between the two points.

The scale on a map of Texas shows that 1 inch represents 20 miles. The actual distance from Austin to Dallas is 195 miles. On the map, how many inches apart are the two cities?

Answers

1 inch = 20 miles

so 195 miles is 195/20 = 9.75 inches <==

Final answer:

To calculate the map distance between Austin and Dallas with a scale of 1 inch representing 20 miles, and an actual distance of 195 miles, set up a proportion and solve to find that Austin and Dallas would be 9.75 inches apart on the map.

Explanation:

To find out how many inches Austin is from Dallas on the map, we need to set up a proportion. The scale given on the map is 1 inch represents 20 miles. We know the actual distance between Austin and Dallas is 195 miles. To calculate the distance on the map, we use the proportion 1 inch / 20 miles = x inches / 195 miles.

Cross-multiply to solve for x:

(1 inch) * (195 miles) = (20 miles) * (x inches)

195 inch-miles = 20x inch-miles

Now, divide both sides by 20 miles to solve for x:

x = 195 inch-miles / 20 miles

x = 9.75 inches

So, on the map, Austin and Dallas would be 9.75 inches apart.

You are offered an item for $17.85. If the seller states he normally sells the same item for $19.95, what percentage discount is he offering you?

Answers

Take 19.95 and subtract 17.85 from it to get 2.10. Divide 2.10 by 19.95 to get 0.105. Multiply that by 100 and you get 10.52. So it's 10% or maybe 11% if you're supposed to round. Hope this helps

Answer:

Find out the what percentage discount is seller offering you .

To prove

Formula

[tex]Discouunt\ percentage = \frac{Discount\times 100}{Marked\ price}[/tex]

Discount = Marked price - Selling price

As given

You are offered an item for $17.85. If the seller states he normally sells the same item for $19.95 .

Here

Marked price = $19.95

Selling price = $17.85

Discount = 19.95 - 17.85

= $2.1

Put in the formula

[tex]Discouunt\ percentage = \frac{2.1\times 100}{19.95}[/tex]

[tex]Discouunt\ percentage = \frac{210}{19.95}[/tex]

Discount percentage = 10.5% (Approx)

Therefore the discount is seller offering you is 10.5 % .

In triangle XYZ, m∠Z > m∠X + m∠Y. Which must be true about △XYZ?

Answers

it must be an obtuse triangle

The rule (x,y)→(2x,2y) maps △DEF to △D′E′F′.
Which statement correctly describes the relationship between △DEF and △D′E′F′ ?
the triangles are congruent because △D′E′F′ is a rotation of △DEF , and a rotation is a rigid motion.

The triangles are congruent because △D′E′F′ is a reflection of △DEF , and a reflection is a rigid motion.

The triangles are not congruent because △D′E′F′ is a dilation of △DEF , and a dilation is not a rigid motion.

The triangles are not congruent because △D′E′F′ is a translation of △DEF , and a translation is not a rigid motion.

Answers

The rule (x,y)→(2x,2y) maping △DEF to △D′E′F′ is a dilation which enlarges the pre-image by a scale of 2.

Two triangle are congruent when all the corresponding angles are equal and all the corresponding sides are equal.

Therefore, the triangles are not congruent because △D′E′F′ is a dilation of △DEF , and a dilation is not a rigid motion.

The rule: (x,y)â†’(2x,2y), mapping â–łDEF to â–łDâ€˛Eâ€˛Fâ€˛ can be described as a dilation of â–łDEF into â–łDâ€˛Eâ€˛Fâ€˛. The points are extended away from each other by increasing their distance from the origin, making â–łDâ€˛Eâ€˛Fâ€˛ larger than â–łDEF. A dilation is not a rigid motion, because distance between the points D, E, and F are not preserved, but extended. The triangles are not congruent because they change size.

y=3

Step-by-step explanation:

The required line will be y = 3 which is passing through points (6,3) and (-4,3)

What is the slope of the line?

The slope of the line is defined as the gradient of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Assume two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

To determine the line of passing through points (6,3) and (-4,3)

We have been given two points :(6,3) and (-4,3)

Let the required line will be:

(y - y₁) = [(y₂ - y₁)/(x₂ -x₁ )](x -x₁ )

Here

x₁ = 6, y₁ = 3

x₂ = -4, y₂ = 3

(y - y₁) = [(y₂ - y₁)/(x₂ -x₁ )](x -x₁ )

Substitute values in the above formula

(y - 3) = [(3 - 3)/(-4 -6 )](x -6 )

(y - 3) = [(0)/(-10 )](x -6 )

(y - 3) = 0

y = 3

Therefore, the required line will be y = 3
