Answer 1

Answer:

(x - 1) (x + 3) (x + 5)

Step-by-step explanation:

The constant at the end (-15) can only be factored into 1, 3 and 5, assuming integers. Then, you only have to choose which one of these gets the minus sign.

I'm not sure if this approach will work in general, but it works for this one.

Write y+1=-2x-3 in standard form

Answers

Answer:

y=2x-4

Step-by-step explanation: this looks alot like an equation for slope is it?

Answer:

-2x - y = 4

Step-by-step explanation:

Standard Form: Ax + By = k

Note that while k is a variable, it stands for constant, which means the number with no variables attached would fill in the space. Isolate the constant. Subtract y, and add 3 to both sides:

y + 1 = -2x - 3

y (-y) + 1 = -2x - 3 (-y)

1 = -2x - 3 - y

1 (+3) = -2x - 3 (+3) - y

4 = -2x - y

Set the equation so that it looks like the standard form equation given above:

-2x - y = 4 is your answer.

We multiply both sides by 3.

n-2=90

We add 2 to both sides.

Find the area of the region bounded by the graphs of the equations. y = −x2 + 4x, y = 0

Answers

Answer:

Area = 32/3

Step-by-step explanation:

To find the area bounded by the graphs, we will

need to first equate the y values;

-x^2 + 4x = 0

x^2 = 4x

divide both sides by x

x = 4

So the area we want to calculate now is the integral of -x^2 + 4x from 0 to 4

It takes a thermal drill 13 minutes to bore a hole -39 feet from ground level into a glacier. What is the change in depth after one minute?

Answers

Answer:

3 feet

Step-by-step explanation:

39 divided by 13 = the unit rate per min.

39 divided by 13 = 3

Answer:

-3 feet

Step-by-step explanation:

Divide -39 by 13, since it takes 13 minutes to dig -39 feet:

-39/13

= -3

So, the change in depth after one minute is -3 feet

Write an equation in point-slope form. Crossing the x-axis at x = -3 and the y-axis at y = 6

Answers

Answer:

y = 2x + 6

Step-by-step explanation:

The equation for a linear line is y = mx + c.

We know we want it to cross the y-axis at 6, so the y-intercept (c) can be assumed to be 6.

If we substitute in the x that we want, we end up with this:

0 = m(-3) + 6

m = 2

So now we can form the equation:

y = 2x + 6

x2 − 11x = −30
x2 − 11x = 30
x2 + 11x + 30 = 0
x2 + 11x = 30

Answers

Answer:

x2 - 11x = -30

Step-by-step explanation:

x^2 - 11x = -30

add 30 to the left to make it = to zero

x^2 - 11x + 30 = 0

factor

(x-5)(x-6) = 0

check by FOIL

x times x = x^2

x times -6 = -6x

x times -5 = -5x

-6 + -5 = 11x

-5 times -6 = 30

x2-11=-30

#4. Identify the conclusion of the conditional statement: "I must reset the

clock if it's Daylight Saving time."*

A- I must reset the clock

B-It's Daylight Saving time

C-There is not conclusion

Answers

Answer:

C-There is not conclusion

Step-by-step explanation:

In a conditional statement, there is a hypothesis and a conclusion. It is usually symbolized or represented by " If X, then Y." It is an if - then statement.

Here, the statement "X" is called the hypothesis and the statement "Y" denotes the conclusion. The conclusion is true if the hypothesis is true.

The conclusion of any conditional statement is the immediate phrase that follows the word 'then'.

In the context, the sentence "I must reset the clock if it's Daylight Saving time." , the word 'then' is not there, so we can say that there is no conclusion in the statement.
