Answer:

(-6,2)

Step-by-step explanation:

[tex]f(x)<0[/tex]

We are given [tex]f(x)=x^2+4x-12[/tex].

So we need to solve:

[tex]x^2+4x-12<0[/tex]

First let's find when the expression on the left is 0.

[tex]x^2+4x-12=0[/tex].

The expression on the left is factorable.

Given the coefficient of [tex]x^2[/tex] is 1, all we have to do is see if there are two numbers that multiply to be -12 and add to be 4.

Those numbers are 6 and -2 so the factored form is:

[tex](x+6)(x-2)=0[/tex]

So the solutions can be found be solving the following linear equations:

[tex]x+6=0[/tex] and [tex]x-2=0[/tex].

First equation, you just need to subtract 6 on both sides. [tex]x=-6[/tex]

Second equation, you just need to add 2 on both sides. [tex]x=2[/tex]

So draw a number line with those on it and test the intervals they divide.

--------(-6)--------(2)----------

So we need to test three intervals.

*Plug in a number before -6 to see if that piece of the function is above the x-axis or below. We are looking for below since we want [tex]f(x)<0[/tex].

Let's plug in x=-8

[tex]f(x)=(x+6)(x-2)[/tex] or use [tex]f(x)=x^2+4x-12[/tex].

[tex]f(-8)=(-8+6)(-8-2)[/tex]

[tex]f(-8)=(-2)(-10)[/tex]

[tex]f(-8)=20[/tex] so this piece is above since 20 is positive and not negative.

So we will not include this interval in our answer.

*Plug in a number between -6 and 2 like 0.

[tex]f(x)=(x+6)(x-2)[/tex]

[tex]f(0)=(0+6)(0-2)[/tex]

[tex]f(0)=(6)(-2)[/tex]

[tex]f(0)=-12[/tex] so this piece is under since -12 is negative and not positive.

So our solution includes the interval (-6,2).

*Plug in a number after 2 like 5.

[tex]f(x)=(x+6)(x-2)[/tex]

[tex]f(5)=(5+6)(5-2)[/tex]

[tex]f(5)=(11)(3)[/tex]

[tex]f(5)=33[/tex] so this piece is above since 33 is positive and not negative.

The answer only includes the interval (-6,2).

Answer:

7.25 each or 7.00 if rounded

Step-by-step explanation:

The equation that passes through the points (6, 3) and is parallel to the line x + 3y = 24 is [y = -1/3x + 5].

So, the equation will be:

Now, calculate as follows:

The gradient of the line: -1/3

Therefore, the equation that passes through the points (6, 3) and is parallel to the line x + 3y = 24 is [y = -1/3x + 5].

Answer:

2

Step-by-step explanation:

The answer is 2 because it appears more then 1 which means that it is the highest common factor aka HCF

Hope this helps

The HCF is 2.

What is HCF?

The full form of HCF is the Highest Common Factor. HCF of two or more numbers is the greatest factor that divides the numbers.

For example, 2 is the HCF of 4 and 6.

Given numbers:

10,18 ,20 and 36​

Now splitting the factors of each number we have

10=2*5

18=2*3*3

20=2*2*5

36=2*2*3*3

Hence, the Highest common factor is 2.

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Given Awan has 1 3/4 quarts of tea, also he drinks 2/5 of the coffee, therefore, the amount of coffee that Awan drinks is,

Amount of Coffee = 1 3/4 × 2/5

Amount of Coffee = 7/4 × 2/5 = 14/20 = 7/10 = 0.7 quarts

Answer:

The required function is: [tex]W(t) = 2t+8[/tex]

Step-by-step explanation:

The weight of the baby increases 2lbs per month which means that it is a linear function.

Now given that the initial weight was 8lbs it will remain constant.

Let t be the number of months and as the weight gain is 2 lbs per month, 2t will be the weight gain after t months.

The function can be written as:

[tex]W(t) = 2t+8[/tex]

Hence,

The required function is: [tex]W(t) = 2t+8[/tex]

Answer:

[tex]y=6x+43[/tex]

Step-by-step explanation:

We want the equation of a line that is parallel to [tex]y=6x+1[/tex] which also passes through (-7, 1).

Since the new line is parallel, it must have the same slope as the original line.

The slope of the original line is 6.

Hence, the slope of our new line must also be 6.

We know that the slope is 6.

And it passes through the point (-7, 1).

So, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

Substitute:

[tex]y-1=6(x-(-7))[/tex]

Simplify:

[tex]y-1=6(x+7)[/tex]

Distribute:

[tex]y-1=6x+42[/tex]

Add 1 to both sides. Hence, our equation is:

[tex]y=6x+43[/tex]

Complete question

Every month, Ms. Thomas pays her car loan through automatic payments (withdrawals) from her savings account. She pays the same amount on her car loan each month. At the end of the year, her savings account balance changed by −$2,931 from payments made on her car loan. Describe the total change to Ms. Thomas’ savings account balance after making six monthly payments on her car loan. Model your answer using a number sentence.

Given the following

Savings balance (after 1 year) =

−$2,931

If she pays the same amount on her car loan each month, we are to find the total change to Ms. Thomas’ savings account balance after making six monthly payments on her car loan, this can be expressed as;

$x = 6months savings

Solving both equalities

Savings balance (after 1 year) =

−$2,931

Since 1year = 12months

-$2,931 =12months savings

$x = 6months savings

To get the total savings after 6months we will find x by cross multiplying;

12×x = -2931×6

Divide through by 12

12x/12 = (-2931×6)/12

x = -2931/2

x = -1465.5

Hence Ms. Thomas' savings account balance after making six monthly payments on her car loan is $-1465.5
