Answer:

C. 11x -2

Step-by-step explanation:

Distribute the 1/2 to 8x-4 which simplifies to 4x -2. Add that to 7x and the expression becomes 11x-2.

write the slope-intercept form of the line that passes through the point (1,0) and is parallel to x-y=7. type your answer in the

dlinn [17]

We know that

a) the slope-intercept form of the line---------------> y=mx+b
b) if two lines are parallel both have the same slope
then
passes through the point (1,0) and is parallel to x-y=7

Step 1
Find the slope
x-y=7------------> y=x-7------------> m=1

Step 2
Find the slope-intercept form of the line---> y=mx+b
point (1,0) m=1
0=(1)*(1)+b------> b=-1
y=(1)*x-1--------> y=x-1

the answer is
y=x-1

If Beyoncé performed as many songs as

IceJOKER [234]

Answer:

20 songs

Step-by-step explanation:

Robyn sang a total of 13 songs for a population of 62000 people, the per capita is the ratio of the total songs sang to the total number of people. Hence:

Robyn per capita = songs performed / population = 13 / 62000

Beyonce sang to a population of 91000 people, given that Beyonce and Robyn had the same per capita, therefore:

Beyonce per capita = songs performed / population

13/62000 = songs performed / 91000

songs performed = 13/62000 × 91000 = 19.08

songs performed ≈ 20 songs

Beyonce is expected to sing about 20 songs

Answer:

The correct answer to the exercise is:

Surface area of a circle = 633.1 $mm^{2}$

Step-by-step explanation:

To obtain the surface area of a circle, you can use the formula:

Surface area of a circle = π * $r^{2}$

Where:

π = 3.14 (the exercise give this)
r = Circle radius.

How you can see, in the picture gives you a straight line that passes through the circle side by side, the circle radius is half of that value, then:

r = 28.4 mm / 2
r = 14.2 mm

Now, we can replace the values in the first formula:

Surface area of a circle = π * $r^{2}$

Surface area of a circle = 3.14 * $(14.2 mm) ^{2}$

Surface area of a circle = 3.14 * 201.64 $mm^{2}$

Surface area of a circle = 633.1496 $mm^{2}$

Surface area of a circle = 633.1 $mm^{2}$ (rounded to the nearest tenth).
