Answer:

the required equation is y = ( -2/3 )x -7

Step-by-step explanation:

Given :-

the line passes through the point ( 0 , -7 )

)and slope of the line is ( -2/3 )

• To form an equation when one point and it's slope is given ,

• To form an equation when one point and it's slope is given , we use ;

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variables

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variablesand x1 and y1 are the points where the line meet !

• To form an equation when one point and it's slope is given , we use ;( y - y1 ) = m ( x - x1 )Where , x and y are variablesand x1 and y1 are the points where the line meet ! and m is slope of the tangent !!

y1 = -7

x1 = 0

So, putting all the values in the equation we get ,

[tex](y - ( - 7)) = \frac{( -2 )}{3} (x - 0) \\ \\ y + 7 = \frac{ - 2}{3} x \\ \\ 3y + 21 = - 2x \\ \\ 3y = - 2x - 21[/tex]

[tex]3y = - 21 - 2x \\ \\ y = \frac{ - 2}{3} x - \frac{21}{3 } \\ \\ y = \frac{ - 2}{3} x - 7[/tex]

• Slope intercept form of the equation

• Slope intercept form of the equation y = mx + c

• Slope intercept form of the equation y = mx + c Where , m is slope of the line

• Slope intercept form of the equation y = mx + c Where , m is slope of the line and c is y intercept !!

[ also , we can directly put the value of c = -7 and m = ( -2/3 ) from given ]

Hence , here m = (-2/3 ) and c = -7

So, the required equation is y = ( -2/3 )x -7

Answer:

B. He was not correct since .64 x 100 = 64

Step-by-step explanation:

100 x .64

400 + 6000 = 6400

64.

The question asks if Tyrone's estimation that 100 boxes of macaroni, each weighing .64 pounds, would total 640 pounds. The estimation is correct as the multiplication .64 x 100 equals 640.

The subject of this question is Mathematics and it is a middle school level problem. The question revolves around the concept of simple multiplication and estimation. If Tyrone estimated that 100 boxes of macaroni would weigh 640 pounds based on the fact that one box weighs .64 pounds, he is correct.

This is affirmed by conducting the simple multiplication calculation: .64 (the weight of a single box) multiplied by 100 (the number of boxes) equals 640.

The mathematical representation of this can be expressed as .64 x 100 = 640. Therefore, Tyrone's estimation is correct.

So if I'm going to add this numbers i need them to share a denominator

7/8 + 1 4/8 = 1 11/8 = 2 3/8 so 3 cups would be the best estimate because the 3/8's are important for the exact mesurement

To determine which mixing bowl to use for combining[tex]\frac{11}{2}[/tex]cups of flour, [tex]\frac{3}{4}[/tex] cup of white sugar, and [tex]\frac{1}{8}[/tex] cup of brown sugar, their volumes need to be added, resulting in a total of 2.375 cups. The suitable bowl size is the 3-cup bowl, as it is larger than the combined ingredient volume.

The student's question relates to determining which size of mixing bowl is required to accommodate the ingredients for a recipe, based on their total volume. To solve this problem, we should add the volumes of flour, white sugar, and brown sugar together:

[tex]\frac{3}{4}[/tex] cup white sugar

[tex]\frac{1}{8}[/tex]cup brown sugar

By converting these measurements to a consistent unit (cups) and adding them, we get:

1.5 cups (flour) + 0.75 cups (white sugar) + 0.125 cups (brown sugar) = 2.375 cups

Since the total volume of the ingredients is 2.375 cups, the smallest bowl that can be used is the one that holds more than 2.375 cups. Therefore, the 3-cup bowl will be sufficient for mixing the ingredients.

Answer:

Gemma made $34 more than Leah.

Step-by-step explanation:

Gemma made number of beaded necklaces = 106

Leah made 39 more necklaces than Gemma.

Leah made number of beaded necklaces  = 106 + 39 = 145

a. There are 104 beads on each necklace.

The total number of beads used altogether

= (106 × 104) + (145 × 104)

= 11,024 + 15,080

= 26,104

b. Gemma sold her 106 necklaces for = $14

Total price of her necklaces = 106 × 14

                                               = $1,484

Leah sold her 145 necklaces for = $10

Total price of her necklaces = 145 × 10

                                               = $1,450

Difference in Gemma and Leah's amount = 1484 - 1450 = $34.00

Therefore, Gemma made $34.00 more money than Leah.

Answer:

Step-by-step explanation:

3x+15=3(x+5)

distribute

3x+15=3x+15

infinite solutions

Answer:

Infinite solutions

Step-by-step explanation:

First, you would need to use the distributive property to simplify the equation. When that has been completed you will notice that both sides are the same. Here is what the simplified equation would look like after using the distributive property: 3x + 15 = 3x + 15. If you continue to sole the equation you would get 0 = 0. This means that there are infinite or many solutions to the equation.

Answer:

Step-by-step explanation:

a.  So since it doesn't say anything else after Monday for that week we assume he only got the apples Monday. Now, if you're having trouble figuring out how much he got from selling all 30 try thinking about selling one at a time.  one is 3.45, two is 6.90 and so on.  So you multiply the amount by how many there are.  so 30*3.45.

b.  Second week is similar, 26*3.45

c.   it wants to know how much in total, so just add the two results.  30*3.45 + 26*3.45.

d.  So, each bag has 15.  You can use similar thinking.  one bag is 15, two is 30 and so on.  Writing an expression  means putting a variable in.  let's say x is the number of bags.  To find the number of apples you multiply it by 15.  so 15x.  Now, to find how many apples were gotten int he two weeks we want x to equal the total number of bags, which is 30+26.

If there was something you didn't understand let me know and I will explain it.  

Answer:

a. [tex]\$103.5[/tex]

b. [tex]\$89.7[/tex]

c. [tex]\$193.2[/tex]

d. Expression: [tex]15(30+26)[/tex]

    He picked 840 apples in two weeks.    

Step-by-step explanation:

We know that he sold each bag for $3.45.

a. Let be "x" the amount of money Juwad earned in the first week. To find its value we need to multiply the price of one bag by the number of bags he sold the first week.

Since he sold 30 bags that week,we get:

[tex]x=(\$3.45)(30)=\$103.5[/tex]

b. In the second week Juwad sold 26 bags.

Let be "y" the amount of money Juwad earned in the second week.

We must multiply the price of one bag by 26 bags in order to find the value of "y". This is:

[tex]y=(26)(\$3.45)=\$89.7[/tex]

c. The  amount of money he earned selling bags of apples those two weeks is:

[tex]total\ earned=x+y\\\\total\ earned=\$103.5+\$89.7\\\\total\ earned=\$193.2[/tex]

d. We already know that he picked 30 bags of apple in the first week and 26 in the second week.

Since each bag holds 15 apples, we can wrie the following expression to represent the number of apples he picked in two weeks:

[tex]15(30+26)[/tex]

Evaluating the expression, we get:

[tex]15(56)=840[/tex]

He picked 840 apples in two weeks.

Answer:

The triangle is obtuse, and isosceles.

Step-by-step explanation:

The triangle is obtuse because there is an angle above 90 degrees, which  is 104 degrees. The triangle is also isosceles due to the two lines in the triangle which indicate that the size of each side are equal to each other. For a triangle to be isosceles, there have to be at least two sides equal to each other, and in this case the triangle has those two equal sides.

3 ≤ n < 15

Step-by-step explanation:

1. "n is less than 15” = "n < 15"

2. "n is greater than or equal to 3" = "n ≥ 3"

Reverse the second inequality.

3. "3 is less than or equal to n" = "3 ≤ n"

Combine 3 and 1.

3 ≤ n < 15

Answer:

see explanation

Step-by-step explanation:

If 2 functions are inverses then the x and y- coordinates swap, that is

(x , y ) → (y, x )

Thus

a = - 3.8 ← the x- coordinate of the inverse

b = - 2.6 ← the y- coordinate of the inverse

c = 1.7 ← the x- coordinate of the inverse

d = 4.4 ← the y- coordinate of the inverse

e = 1.0 ← the x- coordinate of the inverse
