What is the slope of the line through (−1,−7) and (3,9)?

Answer:

Option C

Step-by-step explanation:

Just looking at the coordinate plane, you can count the lengths of both of the triangles: Option C’s triangle of the distance between A and B is 3 units, and the distance between B and C is also 3 units. But, Option D’s triangle has a length of 4 and 3, where the distance between A and B is 4 units, and the distance between B and C is 3 units. So choose Option C because the distance between A and B in the triangle is 3 units, and the distance between B and C in the tirangle is also 3 units.

Hope this helps and answers your question! :)

Answer:

a = 14, x = 55, y = 60

Step-by-step explanation:

a: Find the number that is between 10 and 18, 10 + 18 = 28 divide by 2 = 14, so a = 14

x: Due to corresponding angles theorem, so x = 55 degrees

y: Straight line is 180 degrees, and as we can see at the left side of the image there's a straight line where only 55 degrees was identified so 180 - 55 = 125 and since x = 55 degrees due to corresponding angles, the angle above y is 120 also due to corresponding angles. A quadrilateral is 360 degrees, so:

125 + 55 + 120 + y = 360

180 + 120 + y = 360

300 + y = 360

y = 60

Answer:

The price of 1 coat is $59.

Step-by-step explanation:

Given that 2 coats have the same price so in order to find the price of 1 coat, you have to divide by 2 :

2 coats = $118

1 coat = $118 ÷ 2

1 coat = $59

Answer:

1500 points

Step-by-step explanation:

Given

[tex]Initial\ Score = 100[/tex]

[tex]Rate = 2[/tex]

Required

Determine the total score in first 4 games

This question illustrates a geometry progression and will be solved as follows:

[tex]S_n = \frac{a(r^n - 1)}{r - 1}[/tex]

Where

[tex]a = First\ Term = 100[/tex]

[tex]r = common\ ratio = 2[/tex]

[tex]n = 4[/tex]

[tex]S_4 = \frac{100(2^4 - 1)}{2 - 1}[/tex]

[tex]S_4 = \frac{100(16 - 1)}{1}[/tex]

[tex]S_4 = \frac{100(15)}{1}[/tex]

[tex]S_4 = 1500[/tex]

Hence, the score in first four games total 1500 points

Answer:

The correct answer would be B! -7

Answer:

8.90 seconds

Step-by-step explanation:

When the rocket hits the ground, its height ( y ) will be zero. This means we can write the equation as:

So we need to solve that equation:

x₁ = -0.84

x₂ = 8.90

We discard x₁, as it is negative.

So the answer is x₂, 8.90 seconds.

1) About how much medicine did he make in grams?

Dr. Mann mixed

9.357 g of chemical A,

12.082 g of chemical B,

7.502 g of chemical C

We can determine total amount of medicine that was prepared by Dr. Mann by summing up the chemicals (A,B,C)

=( 9.357grams of A + 12.082grams of B+ 7.502grams of C)

= 28.941 grams in total

The next step is to round up those chemicals value to their nearest tenth as asked by question

Dr. Mann mixed

9.357 g of chemical A= 9.4grams

12.082 g of chemical B,=12.1grams

7.502 g of chemical C =7.5grams

2)Estimate the amount of each chemical by rounding to the nearest tenth of a gram before finding the sum.

Then the sum after rounding up to nearest tenth is

(9.4grams +12.1grams + 7.5grams)

=29 gram

Answer:

Option A is correct option

Step-by-step explanation:

We need to find which number sentence is not true.

We will check each option.

Option A

|-20| < 20

We know that |-a|=a

20 < 20 (false)

So, this number sentence is not true.

Option B

|9| = 9

We know that |a|=a

9=9 (true)

So, this number sentence is true.

Option C

|-20|>|9|

We know that |-a|=a

20>9 (true)

So, this number sentence is true.

Option D

|9| < 20

We know that |a|=a

9<20

So, this number sentence is true.

So, Option A is correct option

Answer:

x = 12 , y = 10

Step-by-step explanation:

Let x , y are two numbers.

x > y

1 ) Three times the greater is 18 times their

difference

3x = 18( x - y )

x = 6( x - y )

x = 6x - 6y

6y = 5x

y = 5x/6 ——-( 1 )

2 ) 4 times the smaller is 4 less than twice

the sum of the two

4y + 4 = 2 ( x + y )

2y + 2 = x + y

y = x -2 ——( 2 )

From ( 1 ) and ( 2 ) ,

5x/6 = x -2

( 5x /6 ) - x = -2

( 5x - 6x ) /6 = -2

-x = -12

x = 12

Put x = 12 in equation ( 2 ) , we get

y = 12 - 2

y = 10

Therefore ,

x = 12 , y = 10

The value of the expression after subtraction will be;

⇒ - 23

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

The expression is,

⇒ (t - 8) - (t + 15)

Now,

Subtract the expression as;

⇒ (t - 8) - (t + 15)

⇒ t - 8 - t - 15

⇒ t - t - 8 - 15

⇒ - 23

Thus, The value of the expression after subtraction will be;

⇒ - 23

Determine the relationship between b loaves and f cups

The question shows that the relationships between cups of flour and loaves of bread is direct proportional.

So, we have:

[tex]f\ cups = b\ loaves[/tex]

and

[tex]7\frac{1}{2}\ cups = 3\ loaves[/tex]

Cross Multiply:

[tex]f * 3 = 7\frac{1}{2} * b[/tex]

[tex]3f = 7\frac{1}{2}b[/tex]

Convert fraction to improper numbers

[tex]3f = \frac{15}{2}b[/tex]
