Answer:

[tex] - 2x + 4x = 2 \\ 2x = 2 \\ x = 1 \\ \\ 1 + y = 2 \\ y = 1[/tex]

Answer:

[tex]x=1\\y=1[/tex]

Step-by-step explanation:

Solve by substitution:

[tex]x+y=2\\-2x+4x=2[/tex]

[tex]2x=2;x+y=2[/tex]

Solve [tex]2x+2[/tex] for x:

[tex]2x=2[/tex]

[tex]x=2/2[/tex]

[tex]x=1[/tex]

Substitute 1 for x in [tex]x+y=2[/tex]

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

[tex]1+y=2[/tex]

[tex]y=2-1[/tex]

[tex]y=1[/tex]

[tex]x=1[/tex] & [tex]y=1[/tex]

hope this helps...

Answer:

Axis of symmetry: x = –1; Vertex: (–1, 0); f(x) = –2x2 – 2x – 1

Step-by-step explanation:

What are the vertex and axis of symmetry of the equation?

The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .

Answer:

n = 90 - 62

n = 28º

m = 180 - (62 + n + 27)

m = 180 - (62 + 28 + 27)

m = 180 - 117

m = 63º

Answer:

no

Step-by-step explanation:

Use the vertical line test to determine if it is a function

Since a vertical line touches more than one point on the graph, it is not a function

Answer:

∠FJG= 135

Step-by-step explanation:

∠FJG + ∠GJH = 168 so

(6x - 15) + (x + 8) = 168

7x - 7 = 168

7x = 175

x = 25

plug it in ∠FJG

6(25) - 15 = 135

Answer:

a = 254.5 mm² ( if using accurate value of π)

a = 254.4 mm² (if using 3.14 as approximate value of π)

Step-by-step explanation:

a = πr²

a = π * 9²

a = π * 81

(note using π = 3.1415926536)

a = 254.4690049408

Rounded

a = 254.5 mm²

(a = 254.4 If using π = 3.14)

2. 7 parts are not green. 3. There both equal amounts.

Step-by-step explanation:

Answer:

Orange:

1/4 ÷ 4 = 1/16

1/4 + 1/16 = 5/16

Blue:

1/16 + 1/5 = 21/80

Yellow:

1/4 + 1/16 = 5/16

Green:

1 - 1/5 = 4/5

1/16 + 4/5 = 69/80

5/16 - 21/80 = 1/20

Answer:

x=2

Step-by-step explanation:

the minimum value of y is when x = 2.

Answer:

The minimum is at x = -2

Step-by-step explanation:

f(x) = (x+2)^2 -3

This is in vertex form

f(x) = ( x-h)^2 +k  where (h,k) is the vertex

Since this is an  upwards  opening  parabola the vertex is the minimum

f(x) = (x- -2)^2 -3

The vertex is (-2,-3)

The minimum is at x = -2

Answer:

[tex]d=N700[/tex]

Step-by-step explanation:

From the question we are told that:

Sale price[tex]n=7000[/tex]

Discount percentage [tex]dp=10 %[/tex]

Generally the equation for discount d is mathematically given by

[tex]d=n*dp[/tex]

[tex]d=7000*\frac{10}{100}[/tex]

[tex]d=N700[/tex]

Answer:

Option A.

Step-by-step explanation:

The general transformation works as follows:

T<a,b>(x, y) = (x + a, y + b)

Then for our transformation, we will have:

T<0,7>(x, y) = (x, y + 7)

So now that we know how the transformation works, we need to apply it to the vertices.

Looking at the graph we can see that the vertices are:

X = (-4, -5)

W = (-3, -3)

L = (-5, -2)

Then the new points will be:

X' = (-4, - 5 + 7) = (-4, 2)

W' = (-3, -3 + 7) = (-3, 4)

L' = (-5, -2 + 7) = (-5, 5)

Then the correct option is A.

Step-by-step explanation:

- square root of 10 is irrational because it is less than zero. - square root of 10 is irrational because it is not a whole number.

Upon prime factorizing 10 i.e. 21 × 51, 2 is in odd power. Therefore, the square root of 10 is irrational.

Answer:

below

Step-by-step explanation:

that is the procedure above

fraction of arc RS

ANGLE RcS = 60 °

60°/360°

=1/6

therefore the total fraction is 1/6

The fraction of the whole circle is arc RS = (1/6)

approximate circumference of the circle = 31.4 cm

approximate length of arc RS = 5.23 cm

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.

As per the given data:

Radius of circle with center C = 5 cm

central angle = 60°

∠RCS = 60°

To find out the fraction of the whole circle is arc RS:

arc length = radius × θ {θ is in radians}

∠RCS = 60° = 60° × (π/180°) = π/3

fraction of the whole circle = arc length / circumference

= [tex]\frac{r \times \frac{\pi}{3}}{2\pi r}[/tex] = (1/6)

approximate circumference of the circle = 2πr

= 2π(5)

= 31.4 cm

approximate length of arc RS = r × θ

= 5 × (π/3)

= 5.23 cm

Hence, the fraction of the whole circle is arc RS = (1/6)

approximate circumference of the circle = 31.4 cm

approximate length of arc RS = 5.23 cm

it's just that you have to multiply the number under root and it's any number is square then you can take it out of root.

Answer:

7.2

Step-by-step explanation:

[tex]A^{2} + B^{2} =C^{2} \\6^{2} +4^{2} =C^{2}\\6^{2} = 36\\4^{2} =16\\36+16= 52\\\sqrt{52} = 7.2[/tex]

Given:

Base length of triangle = 6 units

Height of triangle = 4 units

To find:

Length of hypotenuse of triangle

Steps:

Pythagoras theorem states that,

A² + B² = C²

Here A and B represent height and length of triangle, and C represents the hypotenuse of the triangle.

So, implementing our measurements we get

A = 6 units

B = 4 units

C =  C units

    A² + B² = C²

     6² + 4² = C²

    36 + 16 = C²

           52 = C²

         [tex]\sqrt{52} = \sqrt{C^{2} }[/tex]

[tex]\sqrt{2 * 2*13} = C[/tex]

       [tex]2\sqrt{13} = C[/tex]

            [tex]C = 2\sqrt{13}[/tex]

         [tex]\sqrt{13} = 3.6[/tex]

            [tex]C = 2 * 3.6[/tex]

            [tex]C = 7.2[/tex] units

Therefore, the length of the Hypotenuse of the triangle or the length of C is 7.2 units

Geometry

The answer is D because the two sides add up to 180.

Answer:

D. 110°

Step-by-step explanation:

∠1 and ∠2 are supplementary meaning they add up to 180°.

m∠1 + m∠2 = 180°

m∠1 + 70° = 180°

m∠1 = 110°

Answer:

[tex]\text{Integers: }20,\:21,\text{and }22,\\\\\text{Equation: }x+(x+1)+(x+2)=63[/tex]

Step-by-step explanation:

Consecutive integers are defined by integers that follow each other. Therefore, we can set up the following equation:

Let [tex]x[/tex] be the smallest integer, as denoted in the question.

[tex]x+(x+1)+(x+2)=63,\\x+x+1+x+2=63,\\3x+3=63,\\3x=60,\\x=20[/tex]

Therefore, the three integers are [tex]20,\:21,\text{and }22[/tex].

Answer:

26.17 cm²

Step-by-step explanation:

Applying,

A = πr²∅/360................. Equation 1

Where A = Area of the sector, r = radius of the circle the sector was formed from, ∅ = angle subtends by the sector at the center of the circle , π = pie.

From the question,

Given: r = 5 cm, ∅ = 120°, π = 3.14

Substitute these values into equation 1

A = 3.14(5²)(120)/360

A = 26.17 cm²

Hence the area of the sector is 26.17 cm²

Answer:

Step-by-step explanation:

so you have 2 rectangles and you first need to find what the area is for the side opposite 25 which is 9 because the 2 9's are the same as the missing number.

now 16x9=144

and 9x9x9=729

725x25=18225
