Answer 1

Answer:

x =-5 and y = -6

Step-by-step explanation:

In order to get the answer, I used the elimination/addition method

8y-9x= -3 <— I decided to eliminate the y

5y-8x= 10 <— I decided to eliminate the y

5(8y-9x = -3) <— switch up the number of y from the bottom to multiply

-8(5y-8x= 10) <— switch up the number of y from the top to multiply, but have a negative sign to it

So...our new equation will be....

40y - 45x = -15

+ -40y + 64x = -80

________________________

19x = -95

x = -5

8y-9x= -3

8y-9(-5) = -3

8y+45 = -3

- 45 = - 45

8y = -48

y = -6

To convert between units, you need to know the relationship between units. For example, one mile equals 5280 feet. This relationship can now be used as a conversion factor, set up as required by the question. For each conversion, choose the correct arrangement of the conversion factor and complete the calculation. 1. Convert 7860 feet to miles

Answers

Answer:

7860 feet = 1.49 miles.

Step-by-step explanation:

This question is solved using proportions.

One mile equals 5280 feet.

This means that to convert from feet to miles, we divide by 5280.

1. Convert 7860 feet to miles

7860/5280 = 1.49

So

7860 feet = 1.49 miles.

Well first of all (most important) I should find out what the words mean to me (since the questions only show definitions) and I know that decompose means breaking down a number and DISTRIBUTIVE PROPERTY is a state and that’s what makes it really simple. Also, if we said

”To DISTRIBUTIVE PROPERTY a number means to break it into parts.” Wouldn’t sound proper. :3

Answer:

Angle DCA = Angle CAB

Angle A + Angle B + Angle C = 180°

18 + 3x + 3x = 180

27°

Step-by-step explanation:

For 1:

Angle DCA = Angle CAB (Alternate angles are equal)

Angle DCA = 18°, Hence, CAB = 18°

2)

Angle A + Angle B + Angle C = 180° (sum of interior angles in a triangle)

3.)

Angle A = 18°

Angle B = 3x

Angle C = 3x

18° + 3x + 3x = 180°

4.)

18 + 3x + 3x = 180

18 + 6x = 180

6x = 180 - 18

6x = 162

x = 162 / 6

x = 27°

Consider the circles shown. Circle A has a diameter of 6 centimeter. Circle B has a diameter of 25% greater than Circle A

Determine the circumference for Circle B. Use 3.14 for pi.

Answers

Answer:

23.5 cm

Step-by-step explanation:

Step one:

Given data

Circle A has a diameter of 6 centimeter

Circle B has a diameter of 25% greater than Circle A

Step two:

Let us find the diameter of circle B

25% of 5 is given as

=25/100*6

=0.25*6

=1.5 cm

Circle B

= 6+1.5

= 7.5 cm in diameter

radius= 7.5/2= 3.75cm

We know that

Circumference= 2πr

C= 2*3.142*3.75

C=23.5 cm

Answer:

y=4x+3

Step-by-step explanation:

First, see where the line intercepts at the y-axis and use the y-value(which is 3). Then to find the slope(m), use the slope equation y{2}-y{1}/x{2}-x{1}.

Apply this formula to the coordinates(0,3) and (1,7):

7-3/1-0

This will then equal to

4/1

This can be simplified to:

4

Applying the y-intercept value 3 and the slope 4 to the equation:

Solve with elimination method

Answers

Answer:

For the first equation the answer for "X" will be,

[tex]x = \frac{ - 4 - y}{2} [/tex]

if you want me to solve for y instead then the answer will be,

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

for the second equation the answer for "X" will be,

[tex]x = \frac{1 + 3y}{5} [/tex]

If you want me to solve for y instead then the answer will be,

[tex]y = - \frac{1 - 5x}{3} [/tex]

Multiply entire first equation by 3 so the y variables will cancel when you add the equations.

6x +3y =-12
5x -3y =1

Add the equations.

11x =-11
X=-1

Now use that value for x in either equation to find y.

2(-1) +y= -4
-2+y =-4
Y =-2

Solution is (-1, -2)

Answers

Answer:

The equation of the line is:

y = -3/4x + 1

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

m is the slopeb is the y-intercept

Given the points

(0, 1)(4, -2)

Determining the slope between (0, 1) and (4, -2)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:1\right),\:\left(x_2,\:y_2\right)=\left(4,\:-2\right)[/tex]

[tex]m=\frac{-2-1}{4-0}[/tex]

Refine

[tex]m=-\frac{3}{4}[/tex]

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

As

The point (0, 1) is given.

It means at x = 0, the vaule of y = 1

Thus, the y-intercept b = 1

now substituting m = -3/4 and b = 1 in the slope-intercept form of line equation

y = mx+b

y = -3/4x + 1

Therefore, the equation of the line is:

y = -3/4x + 1
