Answer:

Step-by-step explanation:

y= -5x _

y=-7x-14

—————— (y-y=-5x-(-7x)-14)....

0=-2x-14 => x=-7 => y=-5*(-7)=35

Answer: x = -7 and y = 35

Step-by-step explanation: STEPS USING SUBSTITUTION

y= -5x

y= - 7x - 14

consider the first equation. Add 5x to both sides.

y + 5x = 0

consider the second equation. Add 7x to both sides

y + 7x = -14

to solve a pair of equations using substitution, first solves one of the equations for one of the variables then substitute the result for that variable in the other equation. and so goes on

Answer:

50% decease

Step-by-step explanation:

A change from 8 to 4 represents a negative change (decrease) of -50%

Use the formula found below on this webpage to find the percent change by replacing the given values:

Percent = New - Old/Old x 100

Percent = 4-8/8 x 100

Where: 8 is the old value and 4 is the new value. In this case we have a negative change (decrease) of -50 percent because the new value is smaller than the old value.

Hence, 50% decrease

Check Answer:

8 x 50% = 4

8 - 4 = 4

Hence, 50% decrease is the correct answer.

Answer:

No, a polygon cannot have a decimal number of sides.

Explanation:

using the formula:

14 = 360 ÷ number of sides

1/number of sides = 14/360

number of sides = 360/14    

number of sides = 25.71428571    

Answer:

all polygons have exterior angles that totL to 360 degrees from triangles to 20-gons. so 360 divided by 14 is 25.71 sides which is not possible because what would .71 of a side look like....now this is assuming that you were referring to regular polygon with all sides the same. I suppose you could gave a polygon with a whole number of sides but the relationship between the exterior angles could be such that not all of the angles have the same degree measure. I would say that an exterior angle for any polygon would need to be greater than 0 but less than 360. so my answer is yes it could be possible le

Answer:

1.6 < x < 9.6

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is in the range

difference of 2 sides < x < sum of 2 sides , that is

5.6 - 4 < x < 5.6 + 4

1.6 < x < 9.6

Step-by-step explanation:

I assume we are simplifying

1) -6k+7k = k

2) 12r-8-12 = 12r-20

3) n-10+9n-3 = 10n-13

4) -4x-10x = -14x

I did the quiz, hope it helped! <3

Answer:

1. At Kohls Mrs. House would pay $45.00 because %25 = $15 so I just subtracted %.60.00-$15.00.

2.((Number × Percent/100)) + Number

((38 × 15/100)) + 38

5.7 + 38

= 43.7

3. I say that Mrs. House should go-to target. And just by $1.30.

At Kohls, the speaker would be at $45.00.

At target, the speaker would be at $43.70.

$45.00 - $43.70 = $1.30

Answer:

A.factor the left side of the equation

sorry but to tell u the answer, I need to know this

is there an equal sign between 9 and 10 or it's just a minus sign?

I mean if it is a minus sign the first thing to do to solve the equation is 9-10 which gives you -1. but if there is an equal sign the first step is to subtract 10 from both sides of the equation which means your answer will be option B.

Answer:

x=37

Step-by-step explanation:

Area of triangle = x+x+x=180
= 78+65+x=180
=143+x=180
=x=180-143 (bring 143 to the otherside)
x=37

In the given figure, We are to find the respective value of x .

Solution :

We know that,

Sum of all the angles of the triangle = 180°

So,

[tex] \qquad \sf \dashrightarrow{ x {}^{ \circ} + 65 ^{ \circ} +78 ^{ \circ} = 180}[/tex]

[tex] \qquad \sf \dashrightarrow{ x ^{ \circ} + 143^{ \circ} = 180^{ \circ}}[/tex]

[tex] \qquad \sf \dashrightarrow{ x ^{ \circ} = 180^{ \circ}} - 143^{ \circ}[/tex]

[tex] \qquad \bf \dashrightarrow{ x ^{ \circ} = 37^{ \circ}}[/tex]

Therefore, The value of x is 37°

Answer:

Rounded answer: 9.4 in

Step-by-step explanation:

Circumference: 2 times radius times pi

Or in this case: Diameter times pi

Therefore, 3 times pi

= 9.4247779607694

Or if rounded

= 9.4

Rewrite the equation in slope- intercept form.

3(y-1) = 2x + 2

Use the distributive property

3y-3 = 2x + 2

Add 3 to both sides

3y = 2x + 5

Divide both sides by 3

Y = 2/3x + 5/3

Slope = 2/3

Answer:

45π

Step-by-step explanation:

To find the area of a circle the formula is πr².

To find the shaded region we will subtract the area of the small circle from the area of the big circle.

Area(big circle)=π9²=81π

Area(small circle)=π6²=36π

81π-36π= 45π

Answer:

80°

Step-by-step explanation:

the triangles are symmetrical. therefore their angles will be equal.

interior angles of a triangle = 180°

180° - 30° - 70° = m<D

80° = m<D

Answer:

It could be either of two ways:

8

x

+

10

or

8

(

x

+

10

)

Explanation:

The wording is a little unclear because this could be done in two ways:

8

x

+

10

or

8

(

x

+

10

)

The first one is "the product of 8 and a number, increased by 10"

The second is "the product of 8, and a number increased by 10"

The one you might write depends on how you say the statement!

In either case, when you read the phrase "a number" in algebra, you make this the variable - whatever letter you prefer (does not have to be

x

!)

Step-by-step explanation:

The verbal statement of the given algebraic expression gives us; 5(q + 6) = 88

Now, we are told that the product of 5 and q increased by 6 yields 88. Thus, the expression gives us;

5(q + 6) = 88

Therefore we can conclude and say that the verbal statement of the algebraic expression gives us;

5(q + 6) = 88

The Volume of crystals is 160 mm³ while the area of the base is 20 mm².

Volume is the amount of space occupied by a three dimensional shape or object.

Area of triangle = (1/2) * DF * height

Height = 10 - 6 = 4 mm, DF = AC = AB + BC = 2 + 3 = 5 mm

Area of triangle = (1/2) * 5 * 4 = 10 mm²

Volume of triangle prism = Area of triangle * AG = 10 * 4 = 40 mm³

Volume of rectangular prism = A to F * AC * AG = 6 * 5 * 4 = 120 mm³

Volume of crystals = 120 + 40 = 160 mm³

Area of base = AC * AG = 5 * 4 = 20 mm²

The Volume of crystals is 160 mm³ while the area of the base is 20 mm².

D=2^2-4*(-4)*5=4+80=84

x1,2 = (-2±√(84))/10

x1= (-2+√(84))/10 = (-2+√(4*21))/10 = (-2+2√(21))/10 = (-2(1-√(21))/10   =               -(1-√(21))/5
