Write the equation of a line going through (-3,1) and (-2,4) in point slope form using the slope you got ( I got -3 for slope) and the first point given.

Answers

Answer 1

Answer:

y = -3x + 10

Step-by-step explanation:

y = mx + b

plug in numbers to the equation

1 = (-3)(-3) + b

multiply the slope -3 and -3

1 = (9) + b

subtract 9 from both sides

-8 = b

Now plug in the slope and b

y = -3x - 8

Answer 2

Answer:

The equation I got was y= 3x + 10

Step-by-step explanation:

All you need to do is use the formula y= mx + b.

What is the length of DC?
O 2 units
O 3uníts
O 6uníts
O 9 unit

Answers

Answer:

The correct option is;

3 units

Step-by-step explanation:

From the given figure, we have that segment DE is parallel to segment CB of triangle ABC

According to triangle proportionality theorem we have that segment DE which is parallel to segment CB of triangle ABC, divides the other two sides the triangle ABC proportionally

We have;

[tex]\overline {DC}[/tex]/[tex]\overline {AD}[/tex]= [tex]\overline {EB}[/tex]/[tex]\overline {AE}[/tex]

[tex]\overline {DC}[/tex]/9 = 4/12

[tex]\overline {DC}[/tex]= 9 × 4/12 = 3

[tex]\overline {DC}[/tex]= 3 units

The length of the segment DC = 3 units.

The Jackson's dinner cost $125. They left $21.25 as a tip. What was the percentage of the tip? Please explain and help me! THANK YOU!!!

Answers

Answer:

17%

Step-by-step explanation:

to find the percentage of something, you have to fill out the following formula:

x/100 = 21.25/125. Basically that is saying that some percent out of 100 is equal to 21.25 out of 125. To solve that, you have to cross multiply:

125x = 2125

then you have to divide, to single out x:

the answer is 17

so it is 17%

17%
Divide the tip by the amount dinner was and you get your percentage for the tip

Answers

Answer: 6^30 (the last option)

Explanation:

In the numerator it is a power raised to a power so you multiply. It gives you 6^36.

Now you have:

6^36 / 6^6

Now you subtract the powers when you are dividing because that is the exponent rule

36 - 6 = 30

Solve: -1/2x +2=-x+7​

Answers

Answer:

x = 10

Step-by-step explanation:

-1/2x + 2 = -x + 7

multiply by 2 so that -1/2x becomes -x

(-1/2x + 2 = -x + 7)2

-x + 4 = -2x + 14

subtract 4 from both sides

-x = -2x + 10

add -2x to both sides

x = 10

A bag of coins contains only quarters and dimes.
• The number of dimes in the bag can be represented by x.
• The number of quarters is 6 more than twice the number of dimes.
• There are a total of 276 coins in the bag.
What is x, the number of dimes in the bag?

helpp pls​

Answers

Answer:

Number of dimes in the bag = 90

Number of quarters in the bag = 186

Step-by-step explanation:

Let

x = Number of dimes in the bag

y = Number of quarters in the bag

= 2x + 6

Total = 276

276 = x + 2x + 6

276 = 3x + 6

276 - 6 = 3x

270 = 3x

x = 270/3

= 90

x = 90

Number of dimes in the bag = 90

Number of quarters in the bag = 2x + 6

= 2(90) + 6

=180 + 6

= 186

Total = Number of dimes in the bag + Number of quarters

= 90 + 186

= 276

whats the geometric mean of 1/2 and 8

Answers

Answer:

4

Step-by-step explanation:

1/2 of 8 is 4

Answer is 2. Geometric mean takes the n-th root of the product of the values. So 1/2*8=4, and since there are two numbers, you take the 1/2 root or square root.

So the answer is the square root of 4 which is 2.
