Answer:

See explanation

Step-by-step explanation:

From the attachment, the question has been answered. However, the explanation is as follows;

Given that

[tex](x,y) = (7,4)[/tex]

This means that

[tex]x = 7[/tex]

[tex]y = 4[/tex]

See attachment (1)

Step 1: Locate point 7 on the x axis

Step 2: Locate point 4 on the y axis

Trace these two points until they intersect.

The point at which they intersect, is the required point (7,4) --See attachment (2)

Answer:

The equation is;

x^2 + 4x + 4 = 0

Step-by-step explanation:

Here, we want to give a quadratic equation with a real solution that has a multiplicity of two

Generally, there are only two solutions to a quadratic equation since it is a polynomial of degree two

Since we have a multiplicity of 2, it means that the real roots are repeated

Let us have a solution of x = -2

With the multiplicity;

we have x + 2

So let us expand this

(x+2)(x+2)

= x^2 + 4x + 4

The equation is;

x^2 + 4x + 4 = 0

Answer:

Step-by-step explanation:

x^2 - 9x + 14

(x - 7)(x - 2)

Answer:

x = 57

Step-by-step explanation:

XZ divides <WXY into two equal parts. Which implies that:

m<ZXY = m<ZXW

Therefore:

m<WXY = 2(m<ZXY)

m<ZXY = 58°

m<WXY = 2x + 2

Plug in the values into the equation

2x + 2 = 2(58)

2x + 2 = 116

2x = 116 - 2 (subtraction property of equality)

2x = 114

x = 114/2 (division property of equality)

x = 57

Answer:

AAS

Step-by-step explanation:

AAS stands for Angle-Angle-Side. Here, you are given two angles and one side that is not included in the angles that are corresponding to the angles and side of another triangle, so they are congruent by the AAS rule.

You may be asking why the ASA (angle-side-angle) is not applicable. This is because the side in the ASA rule should be between the two angles, in this case, the 10-unit-side is not in between the two angles but rather nearer to the angle 70°, so ASA is not the right answer.

Arc length is equal to its corresponding central angle.

That means that the arc measures 120° too.

Answer:

≈ 4.2 cm

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × [tex]\frac{120}{360}[/tex] ( r is the radius )

    = 2π × 2 × [tex]\frac{1}{3}[/tex]

   = 4π ÷ 3

   ≈ 4.2 cm ( to 1 dec. place )

Answer:

lines b and c are perpendicular

Step-by-step explanation:

Use slope

slope for parallel is the same

slope for perpendicular is negative reciprocal

line a slope- 1-3/-2-0 is -2/-2 or 1

line b slope- 1-4/4-6 is -3/-2 or 3/2

line c slope- 3-1/1-4 is 2/-3 or - 2/3

none are the same so none are parallel

- 2/3 is the negative reciprocal of 3/2 so lines b and c are perpendicular

Equality Properties

Step-by-step explanation:

Step 1: Define equation

-12(a - 2) = -50

Step 2: Solve for a

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Here we see that -50 does indeed equal -50.

∴ a = 37/6 is a solution of the equation.

Answer:

a = [tex]\frac{37}{6}[/tex]

Step-by-step explanation:

-12(a - 2) = -50

-12a + 24 = -50

-12a = -74

a = [tex]\frac{74}{12}[/tex] = [tex]\frac{37}{6}[/tex]

Answer:

Use a calculator to divide the two values (small over big) to get 14/35 = 0.4

Now multiply that result by 100 to convert to a percentage

0.4*100 = 40%

he has ridden 40% of the course so

Answer: (6, 9) I believe. If you graph the two points, you can see that the slope is 5x (Up 5, right 1). If you make another point on that line, you would raise it from (5, 4). So B = (6, 9). Comment if you need more explaining

Answer:

x = [tex]-\frac{41}{19}[/tex]

y = [tex]\frac{7}{19}[/tex]

Step-by-step explanation:

2x = 10y - 8

3x + 4y + 5 = 0

2x = 10y - 8

x = 5y - 4

3x + 4y + 5 = 0

3 ( 5y - 4 ) + 4y + 5 = 0

19y - 7 = 0

19y = 7

y = [tex]\frac{7}{19}[/tex]

x = 5y - 4

x = 5 ( [tex]\frac{7}{19}[/tex] ) - 4

x = [tex]-\frac{41}{19}[/tex]
