Identify the equation in slope-intercept form for the line with the given slope that contains the given point. Slope =2; (1,4)

1 answer:

3 0

Slope-intercept form: y=mx+b, with m being the slope and b being the y-intercept. First, plug in the given slope into the slope form:

y=2x+b

Now, given the coordinates (1,4), you can plug the coordinates into the equation for x and y respectively, to solve for b (the y-intercept).

4=2(1)+b

4=2+b

Subtract 2 from both sides.

2=b

The y-intercept is 2.

Now, plug that into the equation:

y=2x+2

The answer is y=2x+2.

I hope this helps :)

V2 - 15 = -2v Solve the Quadratic. What are the 2 solutions?

ki77a [65]

Answer:

v=-5 and v=3

Step-by-step explanation:

We are given that

$v^2-15=-2v$

We have to find two solutions of quadratic equation.

$v^2+2v-15=0$

Using addition property of equality

$v^2+5v-3v-15=0$ (By using factorization method)

$v(v+5)-3(v+5)=0$

$(v+5)(v-3)=0$

Substitute each factor equal to 0

$v+5=0$ and $v-3=0$

$v=-5$ and $v=3$

Hence, two solutions of quadratic equation are

v=-5 and v=3

The freezing point of water is 32º F. Tim added potassium and found

HACTEHA [7]

Answer:

The freezing point of the water with the added potassium is 24 degrees Fahrenheit.

Step-by-step explanation:

To find the freezing point of the water with the added potassium, you need to subtract 8 degrees from the initial freezing point of water, This is because you know that after adding potassium to water, the freezing point went down by 8 degrees Fahrenheit. So you need to subtract 8 degrees from the initial freezing point of water (32 degrees Fahrenheit). 32º F - 8º = 24º F. So the freezing point of the water with the added potassium is 24 degrees Fahrenheit.

Anni [7]

Answer:

31.03%

Step-by-step explanation:

Very simple

6/8.7 and you get the percentage of tree left. Which is 68.97% (rounded

You subtract that from 100 to get how much was removed.

100-68.97=31.03%

WHAT IS THE SLOPE IN THE EQUATION Y = -6X+4

AfilCa [17]

Answer:

-6 is your answer

Step-by-step explanation:

Note the equation: y = mx + b

y = y

m = slope

x = x

b = y-intercept

With the knowledge above, we see that m = slope, which is -6

-6 is your answer
