Answer:

  -4

Step-by-step explanation:

Compare this to the form ...

  y -y1 = m(x -x1)

which is the point-slope form of the equation for a line. Matching the parts of the equation, you see that ...

  • y1 = -3
  • m = -4
  • x1 = -7

m represents the slope of the line. The slope is -4.

Answer:

-4

Step-by-step explanation:

We need to go over point-slope form:

y - y1 = m(x - x1)

In this equation m represents the slope

So, let's convert:

y +3 = -4(x+7)

m being -4, so the slope of the line is -4.

What letter stays the same when reflected over the x-axis
valina [46]

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.p explanation:

Complete the Table
lianna [129]

Answer:

a= 6

b = 7

c = 8

d = 7

e = 6

Step-by-step explanation:

Notice that the bike is 6 feet above the ground to start with, so when it starts rolling, the green dot is exactly 6 feet from the ground, which gives a=6

when the distance covered by the bike is \frac{\pi}{2}, (see first red dot in the attached image), the position of the green dot is exactly 1 foot added to 6 ft= 7 feet

so b = 7

when the distance covered is \pi, now the green dot would be at the top of the wheel (second red dot in the attached image) which involves adding 2 feet to the original 6 feet. That is: c = 8

when the distance covered is \frac{3\pi}{2}, the green dot is at the position of the third red dot in the attached image., that it exactly one foot added to 6 feet = 7 ft which gives the value of d = 7

and finally, when the distance covered is 2\pi. the green dot has completed a full circle and is now again in its lower position (nothing - zero) added to 6 feet =  6ft, giving e = 6.

A box of cereal contains 23.4 ounces. It costs $5.49. What is the cost to the nearest cent of the cereal per ounce
cestrela7 [59]
So in a proportion 23.4 over 5.49 equals 1 over o and multiply 5.49•1=23.4o
5.49=23.4o divide by 23.4 on both sides and that equals 4.26 per oz

Drag the expressions to show the order of their quotients from least to greatest
Damm [24]

Answer:

by solving the divisions

Step-by-step explanation:

  • 8/9 ÷ 7/11 = 8/9 × 11/7 = 88/63 = 1.40
  • 19/12 ÷ 3/10 = 19/12 × 10/3 =190/36 = 5.28
  • 19/12 ÷ 1/15 = 19/12 × 15 = 285/12 = 23.75

8/9 ÷ 3/10 = 8/9 × 10/3 = 80/27 = 2.96.

now from the solutions you can get the least to greatest

1.40 , 2.96, 5.28 and 23.75

After getting answer in decimal form change it to fraction like how they set the question
