$y+6 = \frac 4 5(x+3)$

That's point slope form, a line with slope m through (a,b) is

y - b = m(x - a)

We have a slope m=4/5 and a point (a,b)=(-3,-6)

A slope of 4/5 means for each 5 unit increase in x with get a 4 unit increase in y. So (x,y)=(-3 + 5, -6 + 4) = (2, -2) is also on the line.

Answer: Plot (-3,-6) and (2,-2) and the line joining them.

How do you solve this

Fed [463]

Answer:

x is equal to 55 degrees.

Step-by-step explanation:

In order to find this, we must first realize that the angle next to 160 is equal to 20 degrees. This is because they come together to make a straight line, which is equal to 180 degrees.

Now knowing this, we can find the two congruent angles at the top. Since they form one angle of a large triangle along with the right angle and 20 degrees, we know they combine to be worth 70 degrees. Since they are even, we know each is 35 degrees.

For the final step, we know that the 35 degree angle and 90 degree angle form a triangle with x. Knowing these all add up to 180, we can solve for x.

35 + 90 + x = 180

125 + x = 180

x = 55

The sum of 5 consecutive integers is 200. What is the fourth number in this sequence.

babunello [35]

STEP-BY-STEP SOLUTION:

Let the smallest integer of the five integers = x

x + x + 1 + x + 2 + x + 3 + x + 4 = 200

5x + 10 = 200

5x = 200 - 10

5x = 190

x = 190 / 5

x = 38

Therefore:

Number no. 4 = x + 3 = 38 + 3 = 41

FINAL ANSWER:

Hence, the fourth number in the sequence is 41.

A bag contains pennies nickels and dimes there are 50 coins in all of the coins 16% are pennies and 36%are dimes there are 6 mor

QveST [7]

Answer:

The bag contains $2.39

Explanation 40% of 50 coins is 20 dimes which equals 2 dollars

8 percent is 4 pennies

2.00+ .04 is 2.04

Plus 7 nickels because there are 3 more nickels than pennies 7*5= 35

2.04+.35= 2.39

Fill out each diagram to find the cost of 6 bags of popcorn when 4 bags of popcorn is $3. What is the total cost of 6 bags of po

KiRa [710]

Answer:

hope this helps

Step-by-step explanation:

A context is described, and students generate two sets of values. The purpose of this warm-up is to remind students of some characteristics that make a relationship proportional or not proportional, so that later in the lesson, they are better equipped to recognize that a relationship is not proportional and explain why.

The numbers were deliberately chosen to encourage different ways of viewing a proportional relationship. For 20 ounces and 35 ounces, students might move from row to row and think in terms of scale factors. This approach is less straightforward for 48 ounces, and some students may shift to thinking in terms of unit rates.

There are many possible rationales for choosing numbers so that size is not proportional to price. As long as the numbers are different from those in the “proportional” column, the relationship between size and price is guaranteed to be not proportional. Look for students who have a reasonable way to explain why their set of numbers is not proportional, like “the unit price is different for each size,” or “each size costs a different amount per ounce.”

Ask students to remember the last time they went to the movies. What do they know about the popcorn for sale? What sizes does it come in? About how much does it cost? Tell students that in this activity, they will come up with prices for different sizes of popcorn—one set of prices in which the price is in proportion to the size, and another set of prices in which the price is not in proportion to the size, but is still reasonable. Ask students to be ready to explain the reasons they chose the numbers they did.

Arrange students in groups of 2. Give 2 minutes of quiet work time and then invite students to share their sentences with their partner, followed by whole-class discussion.

A movie theater sells popcorn in bags of different sizes. The table shows the volume of popcorn and the price of the bag.

Complete one column of the table with prices where popcorn is priced at a constant rate. That is, the amount of popcorn is proportional to the price of the bag. Then complete the other column with realistic example prices where the amount of popcorn and price of the bag are not in proportion.

volume of popcorn (ounces) price of bag, proportional ($) price of bag, not proportional ($)
