Answer:

Option A - (x+1)^2-5

Step-by-step explanation:

To find : Which expression represents five less than the square of one more than a number?

Solution :

Writing the expression into numeric form,

The square of one more than a number represents (x+1)^2

Five less than the square of one more than a number represents (x+1)^2-5

The correct expression is given by, (x+1)^2-5

Therefore, Option A is correct.

Through:(4,4),parallel to y=-6x +5
ad-work [718]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

In this case we have the following equation of the line:

y = -6x + 5

Where:

m = -6

By definition, if two lines are parallel then their slopes are equal. Thus, a parallel line will have an equation of the form:

y = -6x + b

Substitute the given point(x, y) :( 4,4)to find "b":

4 = -6 (4) + b\\4 = -24 + b\\4 + 24 = b\\b = 28

Finally, the equation of the requested line is:

y = -6x + 28

Answer:

y = -6x + 28

Find a equation of a line that is perpendicular to y=-4x+3 and passes through the point (4,-1).
Marina86 [1]

Given:

The given equation is:

y=-4x+3

A line is perpendicular to the given line and passes through the point (4,-1).

To find:

The equation of required line.

Solution:

The slope intercept form of a line is:

y=mx+b

Where, m is slope and b is y-intercept.

We have,

y=-4x+3

Here, the slope of the line is -4 and the y-intercept is 3.

Let the slope of required line be m.

We know that the product of slopes of two perpendicular lines is -1. So,

m\times (-4)=-1

m=\dfrac{-1}{-4}

m=\dfrac{1}{4}

The slope of required line is m=\dfrac{1}{4} and it passes through the point (4,-1). So, the equation of the line is:

y-(-1)=\dfrac{1}{4}(x-4)

y+1=\dfrac{1}{4}(x)-\dfrac{4}{4}

y=\dfrac{1}{4}x-1-1

y=\dfrac{1}{4}x-2

Therefore, the equation of the required line is y=\dfrac{1}{4}x-2.

If y = -9 when x = 3, find y when x = -6. when x = -5.
weeeeeb [17]

Answer:

When x is -6, y will be 18

When x is -5 y will be 15

Step-by-step explanation:

Create a proportion

y/x

-9/3 = x/-6  What do we need to multiply 3 by to get 6?  -2, so we will multiply -9 by -2 to get 18

Some people like to solve by cross multiplying.

That would give us

(-9)(-6) = 3x  

54 = 3x  divide both sides by 3

18 = x

Set up the second problem as a proportion

-9/3 = x/-5  This is a little trickier.  I am trying to think what I have to multiply 3 by to get -5.  3(-5/3)  will give me -5, so I will multiply the top number that I know (-9) by (-5/3) to find my x.

(-9)(-5/3) = 45/3  or 15

1. The ratio of girls to boys to parents at the concert is 10:5:4. If there are
Maru [420]

Answer:

1.   228 parents

Step-by-step explanation:

I will do number 1 for you.  I'll let you or someone else do the others.

Let 10x = no. of girls

      5x = no. of boys

      4x = no. of parents

Now, 10x + 5x + 4x = 1083

                        19x = 1083

                            x = 57

(10)(57) = 570 girls

(5)(57) = 285 boys

(4)(57) = <u>228 parents</u>

             1083  total

For real number a, which of the following equations are true ? Select all that apply.
trapecia [35]

ANSWER

\lim_{x \to \: a}(x)  = a

\lim_{x \to \: a}(a)  = a

\lim_{x \to \: 5}(x)  = 5

EXPLANATION

For real number 'a',

\lim_{x \to \: a}(x)  = a

is true because we have to plug in 'a' for x.

\lim_{x \to \: a}(a)  = a

This is also true because limit of a constant is the constant.

\lim_{x \to \: 5}(4)  = 5

is false. The correct value is

\lim_{x \to \: 5}(4)  =4

\lim_{x \to \: 5}(x)  = 5

is also true because we have to substitute 5 for x.

\lim_{x \to \: a}(a)  = x

is also false

The limit should be

\lim_{x \to \: a}(a)  = a
