Answer:

4y

Step-by-step explanation:

youd have to combine like terms..

Answer:

4y

Step-by-step explanation;

since they have something in common which is y,it is possible to subtract.we would be focusing more on the numbers than letters.The like term which is y just paves a way for these numbers to be subtracted.Hence, 6y -2y= 4y

or you can do it this way also

they have something in common which is y,so we factorise

y(6-2)

y(4)

hence y(4) also means 4 x y= 4y

Answer:

The question seems to be incomplete, so i will answer in a general way.

Ok, i guess that here we have two vectors:

a = (Ax, Ay) and b = (Bx, By).

Now we have that:

c = a + b = (Ax, Ay) + (Bx, By) =  (Ax + Bx, Ay + By).

Now, to calculate the magnitude of a vector (x, y) we have:

√(x^2 + y^2)

Then the magnitude of c will be:

IcI = √( (Ax + Bx)^2 + (Ay + By)^2)

And for the direction:

First, the direction is already defined by the vector c.

But a more exact (and easy to read) way is:

When we have a vector (x, y).

The angle between this vector and the x-axis is given by:

Tan(θ) = y/x.

Then in the case of c.

Tan(θ) = (Ay + By)/(Ax + Bx)

θ = ATan( (Ay + By)/(Ax + Bx) )

Step-by-step explanation:

A:3(x+2)=18

Divide each side by 3

3/3(x+2)=18/3

x+2 = 6

This is the same equation as equation B

They will have the same solution since they are the same equation

x+2-2 = 6-2

x = 4

Answer:

You need to multiply/divide both sides by the same constant- they're both equivalent as well.

Step-by-step explanation:

You need to multiply/divide both sides by the same constant- they're both equivalent as well.

This is because solving it you get this

3(x+2)=18

3(x+2) over 3 = 18/3

x+2=6.

That's dividing by a non-zero constant (3).

Step-by-step explanation:

The first multiplier is the number of terms being added.

The second multiplier is one more than the first multiplier, that is

2 + 4 + 6 + 8 + 10 ← has 5 terms being added and 6 is one more than 5, thus

2 + 4 + 6 + 8 + 10 = 5 × 6

Explanation:

In geometry, a translation is where you slide a point or figure some distance left, right, up or down.

A reflection will mirror a point over a line, or you could mirror a point over another point.

A rotation turns a point around a fixed center point.

A dilation scales the figure to be larger or smaller.

The first three transformations mentioned (translation, reflection, rotation) are known as rigid transformations. They keep the figure the same size and shape. A dilation will keep the same shape, but the size will be different, so the before and after figures are not congruent when you apply a dilation.

Answer:

Step-by-step explanation:

∠g and ∠f are the interior angles on the same side of the transversal, therefore they're supplementary.

g + f = 180

4x + 3 + x + 17 = 180

5x + 20 = 180

5x = 180 − 20

5x = 160

x=1605=32

g = x + 17 = 32 + 17 = 49

Since ∠g and ∠e are corresponding angles, they're congruent.

g = e = 49

Answer:

The correct option is;

Domain: [1.8, 12.76]

Range: [0, 590.90]

Step-by-step explanation:

The given function is h(t) = -4.92·t² + 17.69·t + 575

The maximum height reached is found from equating the derivative of the function to 0 as follows;

d(h(t))/dt = d(4.92·t² + 17.69·t + 575)/dt = -2×4.92·t + 17.69

d(h(t))/dt = 0 gives;

-2×4.92·t + 17.69 = 0

-9.84·t + 17.69 = 0

-9.84·t  =  -17.69

t = -17.69/-9.84 = 1.79 ≈ 1.8

h(1.8) = -(4.92×1.8²) + 17.69×1.8 + 575 = 590.9

Also we have from equating the function to zero

h(t) = -4.92·t² + 17.69·t + 575 = 0

(t - 12.75)(t + 9.2) = 0

Therefore, when t = 12.76 h(t) = 0,

Therefore, we have; the domain which is the set of values of the independent variables is [1.8, 12.76]

The range = [0, 590.90].

Answer:

1, 5.1, x, 5.1x

Step-by-step explanation:

5.1x can be split into 5.1 * x, therefore, we know that two of the factors are 5.1 and x. Keep in mind that 2 factors of a number are always 1 and the number itself, so we know that 1 and 5.1x are also factors. The final answer is 1, 5.1, x, 5.1x.

Step-by-step explanation:

Easy way to find the distance between the two numbers is by taking the sum of the absolute values of these numbers.

[tex]|-13| + |28|[/tex]

The absolute value tells the distance of the numbers from zero.

Solving for absolute value.

[tex]13+28[/tex]

Adding the numbers.

[tex]41[/tex]

The distance between -13 and 28 on the number line is 41.

Answer:

(I need the explanation most importantly)

14+(-4) - 8 =10-8=2

(Explanation please)

-8.4 - (19.5.) = - 27.9, (just add them to each other and write -, because both have - in front of them)

(Explanation)

-15 + 8 - (-19.7) = - 7+19,7=12,7 (there is + and - so it will became - 7, and at next there is two - which will turn them into +)

(Explanation)

29.45 - 56.009 - 78.2=−104,759 (all you have to is to put them all together, and than make it 29.45 less, writing - in front of them)

Answer:

  7

Step-by-step explanation:

Working backward, we can find Bob's initial product.

We subtracted 3 to get 1, so we had 4.

We divided by 5 to get 4, so we had 20.

We added 6 to get 20, so we had 14

After Bob multiplied the two numbers together, he had 14. We know that 14 is the product of 2 and 7. The odd number is 7.

Answer: how much you have done

Step-by-step explanation:

Answer:

a.) 98°

Step-by-step explanation:

Angle 5 and angle 8 (82°) are supplementary angles. This means that their sum will make a straight angle of 180°. Make an equation:

[tex]82+x=180[/tex]

Solve for x, the value of angle 5:

[tex]x=180-82\\\\x=98[/tex]

Angle 5 has a  measure of 98°.

Now we know the measure of angle 5. Angle 4 and angle 5 are alternate interior angles, so they are congruent. Therefore, angle 4 has a measure of 98°.

Answer:

Write its y-intercept as zero:

[tex]y=m\,x[/tex]

Step-by-step explanation:

If the line is given in slope-intercept form:

[tex]y=m\,x+b[/tex]

make sure that you keep the value of the slope (m) as it is (because you want a line parallel to this one so it has to have the same slope "m", and change the value of "b" to zero, leaving the line with the following form:

[tex]y=m\,x+0\\y=m\,x[/tex]

This forces the line to have its y-intercept at the value zero (origin of coordinates)

Answer:

Area of rectangle=9×17=153 SQ.ft

Area of semi-circle=π9'2/2

Area of traingle=(1/2)×7×9=31.5

The area of the composite figure is 325.17 square feet

The figure is a composite figure with the following shapes

The dimension of the shapes are:

The area of each shape is:

Semicircle

A = 0.5πr²

This gives

A = 0.5 * 3.14 *9^2 = 127.17

Triangle

A = 0.5 * base* height

This gives

A = 0.5 * 9 * (26 -9 - 7) = 45

Rectangle

A = Length * Width

This gives

A = 9 * (26 - 9) = 153

The area of the figure is the sum of the areas of the individual shapes.

So, we have:

Total = 127.17 + 45 + 153

Evaluate

Total = 325.17

Hence, the area of the composite figure is 325.17 square feet
