Answer:

[1, 4]; 1 = m

Step-by-step explanation:

According to the Point-Slope Formula, <em>y - y₁ = m(x - x₁)</em>, all the negative symbols give the OPPOSITE terms of what they really are, so in this case, the coordinates are [1, 4]. Now, the <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] is <em>1</em><em> </em>because an invisible coefficient is always assumed to be <em>1</em><em>.</em>

Answer:

The slope of the line is 1 and it passes through the point (1,4).

Step-by-step explanation:

If a line passes through a points (x_1,y_1) with slope m, then the point slope form of the line is

y-y_1=m(x-x_1)            .... (1)

The given equation of line is

y-4=(x-1)                .... (2)

We need to find the slope and the coordinates of a point on the given line.

On comparing (1) and (2) we get

m=1

x_1=1

y_1=4

Therefore, the slope of the line is 1 and it passes through the point (1,4).

mafiozo [28]

Answer:

16

Step-by-step explanation:

To solve, we can use an equation finding the average of the siblings'ages.

\frac{14 + 12 + x}{3}  = 14 \\  \ 14 + 12 + x = 42 \\ x = 42 - 14 - 12 \\ x = 16

Terri played 70 tournament chess games during the school year and won 49 of them. What is her win-to-loss ratio?
Scilla [17]

Alright so the answer would be letter B, because

win-to-loss

49 to 21 (You can determine her losses by subtracted the number of wins from her total number of games played)

Now you must simplify your answer

7 is the greatest common factor (GCF) of both 49 and 21

Now divide both 49 and 21 by 7 to get

7 to 3

Brianne's town is building a pool based on a scale drawing that is 20 centimeters by 10 centimeters and uses the scale 1 cm:250
kiruha [24]

Answer:

A=1250m^2

Step-by-step explanation:

From the question we are told that

Dimension of drawing

20 centimetres by 10 centimetres

Scale of drawing

1 cm:250 cm

Generally the the Main dimension of the pool is mathematically given as

L=length\ of\ scaled\ pool*250 cm\\B=length\ of\ scaled\ pool*250 cm\\L=20*250=5000 cm=50m\\B=10*250=2500 cm=25m

Therefore Area Aof main pool is mathematically given as

A=50m*25m=1250 m^2

A=1250m^2

The product of 7 and a number, increased by 3, is equal to twice the number, subtracted from 39. Find the number.
musickatia [10]
It's just an equation, the number you're looking for is X, and then turn the words into an solvable equation with respect to X.

7X + 3 = 39 - 2X
9X = 39 -3 = 36
X = 4
