Answer:

So what you're being asked to do for #4 is graph the line. The y-intercept would be -2, and then a line with a slope of 1/3(rise over run) will go through that y-intercept. For the second one, you need to convert it to y = mx + b form and then do the same thing.

The fourth answer

Step-by-step explanation:

Answer:

{6,9}

Step-by-step explanation:

The table values are given as;

x   y

0  0

2  3

4  6

Take the values as coordinates in form of {x, y} , to have the following;

{0,0} , {2,3} , {4,6}

Find the slope using the coordinates as;

m=Δy/Δx

m=3-0/2-0 = 3/2

The slope m = 3/2

So from the answer choices, the coordinates that can give a slope of 3/2 will be:

{6,9}

The x coordinates increase by 2units while those of the y coordinates increase by 3 units.

The  triangle has three angles X, Y, Z. The measure of angle Y is, 32°. So option B is correct.

An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The inner angle made by the intersection of two polygonal sides.

Exterior angles:- The outer angle made by the intersection of two polygonal sides.

Given that,

The measure of angle W is 100°,

And the measure of angle Z is 68°

The exterior angle to angle X is W

The measure of angle Y = ?

If the exterior angle to angle X is W then it can be written as,

angle X = 180° - W

             = 180° - 100°

             =  80°

angle Z = 68°

It is known that,

sum of all the interior angles of the triangle is 180°

X + Y + Z = 180°

80°  + Y + 68°  = 180°

Y = 32°

Hence, the value of angle Y is 32°

When a figure or a shape is dilated, the size of its image will either be enlarged or compressed.

The scale of dilation from A to B is 1.5

See attachment for the image that completes the question.

Using a ruler, we have the following measurements

[tex]\mathbf{A = 1\ inch}[/tex]

[tex]\mathbf{B = 1.5\ inches}[/tex]

The scale factor (k) from A to B is:

[tex]\mathbf{k = \frac BA}[/tex]

This gives

[tex]\mathbf{k = \frac {1.5\ inches}{1\ inch}}[/tex]

[tex]\mathbf{k = \frac {1.5}{1}}[/tex]

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

A toy robot moves 10 feet in 12 seconds at a constant speed.

Now,

At a constant speed,

In 12 second = 10 feet

So, In 1 second = 10 / 12 feet

                        = 0.83 feet

Thus, The robot move 0.83 feet in one second.

The required algebraic representation for a rotation 180° clockwise is -x, -y. Option D is correct.

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.

here,
When rotation 180° clockwise takes place then the sign of the coordinate is reversed as if it is positive then it becomes negative and vice versa.

So the algebraic representation for a rotation 180° clockwise of (x, y) is (-x, -y).

Thus, the required algebraic representation for a rotation 180° clockwise is -x, -y. Option D is correct.

  (c) angle EOA

  (d) angle AOH

Step-by-step explanation:

(b) The rays of vertical angles are opposites that form intersecting lines.

The opposite of ray OG is OF. The opposite of ray OB is OA, so the vertical angle to GOB is angle FOA.

__

(c) The opposite of ray OB is OA, so the supplement to angle EOB is angle EOA.

__

(d) Similarly, the supplement to angle BOH is angle AOH.

Comment on supplementary angles

Angles that form a linear pair are supplementary. Angles do not have to form a linear pair to be supplementary. They merely have to have a sum of 180°. Here, the supplementary angles of interest do form a linear pair, so finding the other angle of the pair means only finding the other point that names the line being formed by the pair.

Answer:

The dishwasher will use 80 gallons of water to wash 10 loads of dishes.

Step-by-step explanation:

Given,

Water used for 4 loads of dishes = 32 gallons

Ratio of water used to load of dishes = 32:4

Let,

x represents the gallons of water required for 10 loads of dishes.

Ratio of water used to load of dishes = x:10

Using proportion

Ratio of water used to load of dishes :: Ratio of water used to load of dishes

Product of mean = Product of extreme

Dividing both sides by 4

The dishwasher will use 80 gallons of water to wash 10 loads of dishes.

Answer: It would be 80 gallons of water that the dishwasher will use to wash 10 loads of dishes. To figure this out you would need to divide 32 by 4 which would equal 8. You would do this to figure out how many gallons of water a dishwasher needs to wash 1 load of dishes. Then you would multiply 8 times 10 which would equal 80.

Rewriting the whole as an Equivalent Fraction

3.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  3  as the denominator :

         -4     -4 • 3

   -4 =  ——  =  ——————

         1        3  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(x-10) - (-4 • 3)     x + 2

—————————————————  =  —————

When a fraction equals zero :

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 x+2

 ——— • 3 = 0 • 3

  3

Now, on the left hand side, the  3  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :
