Four times the quantity of a number plus six

Answer:

False B=1

Step-by-step explanation:

10b+18=28

Subtract 18 both sides.

10b=10

Divide 10 both sides.

b=1

Answer:

after 6 years

Step-by-step explanation:

thats when the lines intersect, (6,300)

There will be equal enrollment in Spanish and French classes after 6 years from now.

The red line shows the number of students enrolled in French class each year from now and blue line shows the number of students enrolled in Spanish class each year from now.

The point of intersection of the lines is the point which lies in both the line.

So, it represents the point or time when there are same number of students enrolled in both French and Spanish classes.

From the graph, we can see that the two lines at a point [tex](6,300)[/tex]. The value on the [tex]x[/tex]-coordinate shows the years from now. So, we can say that there will be equal number of students enrolled in two classes after 6 years.

==============================================

Explanation:

The degree of separation from the two cities is 30-7 = 23 degrees.

Let's say the point C is at the center of the earth. This would mean angle BCA is 23 degrees.

Any longitude line helps form what is known as a great circle or orthodrome. This is a math term that describes a circle that is centered at the same location as the sphere's center. Imagine that you can wrap a string around the earth and this string only follows this particular longitude line. This string is effectively a vertical equator in a way. The question is: what is the length of this string?

Well that would be the circumference of the circle with radius 3960 miles because the longitudinal circle has the same radius as the sphere.

That approximates to...

C = 2*pi*r

C = 2*pi*3960

C = 24,881.4138164311

C = 24,881.41

So a bit less than 25 thousand miles. I used the calculator's stored version of pi rather than something like 3.14 to get the best accuracy possible. This is the full string's length if we want to travel the entire distance around the globe but stay entirely on this particular longitude line

We don't want the full string's length. Instead, we want just a fractional portion of it. Specifically, we want 23/360 of it because of the central angle of 23 degrees. This will give us the distance between the two cities.

So (23/360)*24,881.4138164311 = 1,589.64588271642

This then rounds to 1589.65 when rounding to the nearest hundredth.

The distance between the two cities is approximately 1589.65 miles

This is comparable to the driving distance from Los Angeles, CA to Houston, TX (approximately 1547 miles).

(10y - 4) + (7y + 8) + (7y - 5) + (4y - 5) =

= 10y - 4 + 7y + 8 + 7y - 5 + 4y - 5 =

Step-by-step explanation:

Cost of 1 bag of lemons = $x

Cost of 8 bags of lemons = 8*x = 8x

Cost of 8 bags of lemons = Total cost - cost of the egg

8x = $39.62 - $6.74

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Answer:

c.

Step-by-step explanation:

Starting with the multiplications, first the multiply matrix A by -4, so we multiply every value in the matrix by -4 and we get

16 16 -4

-4 -16 -28

-8 -12 -12

Then we do the next multiplication which is 8 by matrix B, so once again we multiply every value in the B matrix by 8

16 72 -72

64 64 -16

32 80 8

Now that we did both multiplications, just need to sum the results, so we sum each value of matrix A with the value on the matrix B that's on the same spot

16 + 16 16 + 72 -4 + (-72)

-4 + 64 -16 + 64 -28 + (-16)

-8 + 32 -12 + 80 -12 + 8

And the final result is

32 88 -76

60 48 -44

24 68 -4

So it's option c

Step-by-step explanation:

[tex]2-\frac{1}{8}y=11+\frac{7}{8}y[/tex]

➠ Subtract 2 from both sides:-

[tex]2-\frac{1}{8}y-2=11+\frac{7}{8}y-2[/tex]

[tex]-\frac{1}{8}y=\frac{7}{8}y+9[/tex]

➠ Subtract 7/8y  from both sides:-

[tex]-\frac{1}{8}y-\frac{7}{8}y=\frac{7}{8}y+9-\frac{7}{8}y[/tex]

[tex]-y=9[/tex]

Answer:

y = -26

Step-by-step explanation:

[y = 2 - 2x] + [y = -16 + 2(x - 3)^2​]

y = -16 + 2x - 6^2

y = -16 + 2x - 6^2 + 2 - 2x

y = (+2x - 2x) - 16 - 6^2 + 2

y = -16 - 6^2 + 2

y = -16 - 12 + 2

y = - 28 + 2

y = -26

This ratio would be 12:1

Step-by-step explanation:

There's 12 gallons of water to 1 cup of cleaner.

Answer:

you would need 12 gallons of water.

Step-by-step explanation:

The ratio is 4 : 1/3. This means that for every 1/3 cups of cleaner, there is 4 gallons of water.

This in mind, 3 1/3 cups of cleaner would be 1/3 x 3.

Whatever you do to one side, you have to do to the other.

4 gallons x 3 = 12.

Step-by-step explanation

Answer:

MN = 11

Step-by-step explanation:

M___A___Z___N

MZ =MA+AZ

MZ = 5x + 3x -2 = 8x - 2

MZ = AN

8x - 2 = 6(2x-1)

8x - 2 = 12x - 6

12x - 8x = 6 -2

4x = 4

x =4/4

x =1

MA= 5x = 5(1) = 5

AZ = 3x-2 = 3(1) - 2 = 3 -2= 1

MZ = 8x -2 = 8(1)-2= 8-2=6

AN = 12x - 6 = 12(1)-6 = 12 - 6 = 6

MN = MA + AN = 5 + 6 = 11

Step-by-step explanation:

Q1 . (f+g)(x) = f(x) + g(x)

=4x-4 +2x^2 -3x

= 2x^2 + x -4

Q2. (f-g)(x) = f(x) - g(x)

= 2x^2−2 - (4x+1)

= 2x^2 -2 -4x -1

= 2x^2 - 4x -3

Q3. h(x)=3x−3 and g(x)=x^2+3

(h.g)(x) = h(x) × g(x)

= (3x-3) × (x^2 + 3)

=3x^3 -3x^2 + 9x -9

Q4.f(x)=x+4 and g(x)=x+6

(f/g)(x) = f(x) ÷ g(x)

= x+4 / x+6

the domain restriction is x>-6

x<-6

x doesn't equal (-6)

If the two function f(x) and g(x) are to be combined, use basic arithmetic rules,

(f + g)(x) = f(x) + g(x)

(f - g)(x) = f(x) - g(x)

[tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]

(f . g)(x) = f(x) × g(x)

Question 1

f(x) = 4x - 4 and g(x) = 2x² - 3x

[tex](f+g)(x)=f(x)+g(x)[/tex]

Therefore, [tex](f+g)(x)=(4x-4)+(2x^2-3x)[/tex]

                                   [tex]=2x^2+x-4[/tex]

Question 2

f(x) = 2x² - 2 and g(x) = 4x + 1

Since, (f - g)(x) = f(x) - g(x)

Therefore, (f - g)(x) = (2x² - 2) - (4x + 1)

                               = 2x² - 2 - 4x - 1

                               = 2x² - 4x - 3

Question 3

h(x) = 3x - 3 and g(x) = x² + 3

Since, (h - g)(x) = h(x) - g(x)

Therefore, (h - g)(x) = (3x - 3) - (x² + 3)

                                = 3x - 3 - x² - 3

                                = -x² + 3x - 6

Question 4

F(x) = x + 4 and g(x) = x + 6

Since, [tex](\frac{f}{g})(x)=\frac{f(x)}{g(x)}[/tex]

Therefore, [tex](\frac{f}{g})(x)=\frac{x+4}{x+6}[/tex]
