Algebra 1

please explain if you can :)

Step-by-step explanation:

A perpendicular bisector is a line that cuts a line segment connecting two points exactly in half at a 90 degree angle. To find the perpendicular bisector of two points, all you need to do is find their midpoint and negative reciprocal, and plug these answers into the equation for a line in slope-intercept form.

any more help just ask :)

Answer:

[tex]75^{\circ}\text{F}[/tex]

Step-by-step explanation:

Last Wednesday it was 90 degrees Fahrenheit.

Today it is 15 degrees Fahrenheit colder than it was last Wednesday.

So, today's temperature will be the difference of the temperatures of last Wednesday's and today's temperature. We have to find the difference as it is colder today means it is a lower temperature than last Wednesday's.

[tex]90-15=75^{\circ}\text{F}[/tex]

Today's temperature is [tex]75^{\circ}\text{F}[/tex]

Answer:

x= 1/42

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4x+3/7+2=x+5/2

combine like terms (2 and 3/7)

4x+17/7=x+5/2

Step 2: Subtract x from both sides.

4x-x+17/7=x-x+5/2

3x+17/7=5/2

Step 3: Subtract 17/7 from both sides.

3x+17/7−17/7=5/2-17/7

3x=1/14

Step 4: Divide both sides by 3.

3x/3=1/14/3

1/14 * 1/3 = 1/42

x=1/42

Answer:

tanx + cotx =  [tex]\frac{1}{sinxcosx}[/tex]

Step-by-step explanation:

Explanation

Take R.H.S   = [tex]\frac{1}{sinxcosx}[/tex]

            =      [tex]\frac{sin^{2}x+cos^{2}x }{sinxcosx}[/tex]

          =      [tex]\frac{sin^{2}x }{sinx cosx} + \frac{cos^{2} x}{sinxcosx}[/tex]

        = [tex]\frac{sinx}{cosx} + \frac{cosx}{sinx}[/tex]

        = tanx + cotx

tanx + cotx =  [tex]\frac{1}{sinxcosx}[/tex]

Answer:

[tex]A_4[/tex]

Step-by-step explanation:

The cost of the e-readers and the subscription of their services are

[tex]A_1(t)=5t+350[/tex]

[tex]A_2(t)=10t+250[/tex]

[tex]A_3(t)=499[/tex]

[tex]A_4(t)=15t+179[/tex]

The functions are of the form

[tex]A(t)=mt+c[/tex]

Where [tex]m[/tex] is the monthly subscription cost and [tex]c[/tex] is the cost of the e-reader.

So, 15 dollars is the highest subscription cost which is of the 4th e-reader.

Hence [tex]A_4[/tex] has the highest subscription cost.

Answer:

x ≤ 2

Step-by-step explanation:

We can write out the inequality as: 3(x) ≤ 6

You have to divide 3 from both sides, so x ≤ 6/3 which is x ≤ 2.

Answer:

$7.20

Step-by-step explanation:

The first step is to convert 1 1/4 to decimal form. 1/4=0.25, which when added to the 1 gives a total weight of 1.25 pounds. Dividing this by the price to find the unit price, you get 9/1.25=$7.20 per pound of turkey. Hope this helps!

Answer:

u got to let us see the question too... we can't find x just like that-

Answer:

the slope is 3 and 1 and the y intercept is 1 and 1

Step-by-step explanation:

Answer:

Step-by-step explanation:

To write an equation that is perpendicular to a given line, take the negative reciprocal of the given slope. the given slope is 4/3, so the negative reciprocal is -3/4.

Using slope-intercept form of a linear equation, y=mx+b substitute in -3/4 for "m" the slope.

y=-3/4x+b

Now you need to "b" the y-intercept using the given point (-4,-1). Substitute the values in the equation. -1=-3/4(-4)+b simplify

                           -1= 3 + b    subtract 3 for both sides

                           -4=b

         substitue -4 for b.   Now you have    y= -3/4x - 4    this is your answer.

Answer:

23x -y = 43

Step-by-step explanation:

in slope intercept form, we have y=mx+b where m=slope, b= y intercept

first let's simplify the expression 23(x-2)

y-3 = 23x - 23*2

y-3 = 23x - 46

now add 3 to both sides to move numbers to the right hand side

y -3 +3 = 23x -46 +3

y = 23x - 43

convert to standard form by having x and y on one side, numbers on the other.

add 43 to both sides

y+43 = 23x

subtract y from both sides

43 = 23x - y

Answer:

x<-4

Step-by-step explanation:

First you have to add 4 by both sides, which will give you 8x<-32.

Then  just divide both sides by 8 and you should get the same answer.

Given:

Consider the below figure attached with this question.

To find:

The perimeter of the polygon UVWXYZ.

Solution:

All sides and vertical and horizontal. So, we can easily find the side lengths of the given polygon by counting the boxes between two points.

From the figure it is clear that,

UV = 9 units

VW = 2 units

WX = 3 units

XY = 3 units

YZ = 6 units

ZU = 5 units

Now, perimeter is the sum of all the sides.

[tex]Perimeter=UV+VW+WX+XY+YZ+ZU[/tex]

[tex]Perimeter=9+2+3+3+6+5[/tex]

[tex]Perimeter=28[/tex]

Therefore, the perimeter of UVWXYZ is 28 units.

Answer:

For children ages 2 to 5, limit screen time to one hour a day of high-quality programming. As your child grows, a one-size-fits-all approach doesn't work as well. You'll need to decide how much media to let your child use each day and what's appropriate.

Step-by-step explanation:

For kids aged 2 to 5, screen time should be limited to 1 hour per day, and parents should watch the programs with their child. Also, parents should have times when screens are turned off, and bedrooms should be media-free.

Step-by-step explanation:

4x - 8y = 16

8y = 4x - 16

y = 0.5x - 2

Hence the slope is 0.5.

Answer:

1/2

Step-by-step explanation:

Slope from a standard form equation is [tex]-\frac{A}{B}[/tex].

A is 4 and B is -8.

[tex]-\frac{A}{B}=\frac{-4}{-8}= \boxed{\frac{1}{2}}[/tex]

Hope this helps.

Answer:

2 solutions

Step-by-step explanation:

Given

2x² + 3x - 5 ( to solve the quadratic equate it to zero )

2x² + 3x - 5 = 0 ← in standard form

(2x + 5)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

2x + 5 = 0 ⇒ 2x = - 5 ⇒ x = - [tex]\frac{5}{2}[/tex]

x - 1 = 0 ⇒ x = 1

The 2 solutions are x = - [tex]\frac{5}{2}[/tex] , x = 1
