Answer:

Do you really mean by -9 or cause I'm just confused but if you meant by 19 then this could help. I had my mom do whatever she could put as  the answer so yeah

Step-by-step explanation:

a*b=18 ____[1]

a+b=19____[2]

[2] a=19-b ___[3]

put [3] in [1]

(19-b)*b = 18

19b-b^2 = 18

b^2-19b+18 = 0

(b-18)(b-1) = 0

so b=18 or b=1

if b=18 then a=19-18=1

if b=1 then a=19-1=18

SO two factors are 1 and 18

Answer:

y = x + 15 –(1)

x + y = 85

Putting (1)'s value,

x + x + 15 = 85

2x + 15 = 85

2x = 85 - 15 = 70

x = 70/2 = 35

[tex][/tex]

The value of y is 50.

Two simultaneous equations can be formed from the given question:

y - x = 15 equation 1

y + x = 85 equation 2

In order to determine the value of x, subtract equation 1 from 2

2x = 70

Dvidie both sides of the equation by 2

x = 70 / 2

x = 35

Substitute for x in equation 1

y - 35 = 15

y = 35 + 15

y = 50

Landslide, also called landslip, the movement downslope of a mass of rock, debris, earth, or soil (soil being a mixture of earth and debris).

Landslides occur when gravitational and other types of shear stresses within a slope exceed the shear strength (resistance to shearing) of the materials that form the slope.

Answer:

Step-by-step explanation:

The lower left angle of the triangle is vertically opposite to 4x + 17. Therefore the third angle of the triangle is also 4x + 17.

x + 23 + 4x + 17 + 80 = 180                 All triangles have 180o

5x + 40  + 80 = 180                            Collect like terms

5x + 120 = 180                                    Subtract 120 from both sides

     - 120   -120

5x = 60                                               Divide by5

5x/5 = 60/5

x = 12

But you are asked for Angle A

A = x + 23

A = 12 + 23

A = 35

Answer:

It is not a solution because 9 is not greater than 9.

Step-by-step explanation:

Answer:

[tex]C = (1,0)[/tex]

[tex]E = (0.8,0)[/tex]

See attachment for C and E

Step-by-step explanation:

Given

[tex]O= (0,0)[/tex] --- Origin

[tex]CO = 1[/tex] --- distance of C to O

Solving (a): Plot point C

Calculate the coordinates of C using distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}[/tex]

Where:

[tex]O= (0,0)[/tex] ---[tex](x_1,y_1)[/tex]

[tex]C = (x,y)[/tex] -- [tex](x_2,y_2)[/tex]

[tex]d = CO = 1[/tex]

So, we have:

[tex]1 = \sqrt{(x - 0)^2 + (y -0)^2}[/tex]

[tex]1 = \sqrt{x^2 + y^2}[/tex]

Square both sides

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

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

For this solution, we assume y = 0

[tex]x^2 + 0^2 =1[/tex]

[tex]x^2=1[/tex]

Solve for x

[tex]x = 1[/tex]

So, the coordinates of C is: (1,0)

[tex]C = (1,0)[/tex]

Solving (b): Plot point E

We have that E is 4/5 closer to the origin.

This implies that, the ratio is:

[tex]m : n = 4/5:1/5[/tex]

Multiply by 5

[tex]m : n = 4:1[/tex]

So, E is at 4:1 between O and C

Calculate the coordinates of E using:

[tex]E = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]

Where

[tex]O= (0,0)[/tex] ---[tex](x_1,y_1)[/tex]

[tex]C = (1,0)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]m : n = 4:1[/tex]

[tex]E = (\frac{4*1 + 1 * 0}{4 + 1},\frac{4*0 + 1*0}{4 + 1})[/tex]

[tex]E = (\frac{4}{5},\frac{0}{5})[/tex]

[tex]E = (0.8,0)[/tex]
