Write an equation of the line that passes through (-1,4) and is perpendicular to the line shown.
Answer:
y= -3/4x - 4Step-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.
Drake is considering buying one of the four popular e-readers where the e-reader's premium services is a monthly charge. The functions LaTeX: A_1\left(t\right)=\:5t+350,\:\:\:A_2\left(t\right)=10t+250,\:\:\:\:\:A_3\left(t\right)=499,\:and\:\:\:\:\:\:A_4\left(t\right)=15t+179A 1 ( t ) = 5 t + 350 , A 2 ( t ) = 10 t + 250 , A 3 ( t ) = 499 , a n d A 4 ( t ) = 15 t + 179 model the total amount of money A, in dollars, that Drake spends after buying the e-reader and subscribing to t months of the e-reader's premium services. Which e-reader has the greatest monthly subscription cost?
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.

What is the perimeter, in units, of polygon UVWXYZ? Enter your answer in the box.
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.

Write y – 3 = 23 (x – 2) in standard form. PLEASE HELP BEST ANSWER AND EXPLANATION WILL GET BRAINLIEST!!
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

Find an
equation for the perpendicular bisector of the line segment
whose endpoints (7,9) and (-1,3).
are
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.

What is 60% of $55?
$____
Answer:
33
Step-by-step explanation:

Answer:
$33
Step-by-step explanation:
Cross multiply 60/100=x/55
=>60(55)=100x
=>3300=100x
divide both sides by 100 to get x by itself=> 33=x

An average American child aged 0-2 years old has about 915 minutes of screen time in 5 days. 6 times the difference between a child aged 0-2 years (915) and a child aged 3-5 years (X) is the same as the sum of 100 and a child aged 3-5 years (X). How much screen time does an average child (x) have?
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.

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

how many solutions does the quadratic have? 2x^2+3x-5
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
The average temperature in Lincoln in July is 85 degrees. Last Wednesday, it was 90 degrees. Today it was 15 degrees cooler than last Wednesday. What was the temperature today?
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]

Harloe’s cats love Christmas songs. Every day she sings “Jingle Bells” five times, “Silver Bells” twice as many times as “Jingle Bells” and “Silent Night” once before bedtime.
A. How many songs does Harloe sing each day?
B. How many songs does Harloe sing in the weekend?
Answer:
A- 16 songs a day
B- 32 songs in the weekend
Step-by-step explanation:
A- if she songs "jingle bells" 5 times, the sings"silver bells" twice as many times, that would just be like multiplying 5 x 2, which equals 10, then add the 5 times she sings jingle bells, that would be 15. then she sings "silent night" one time which adds on to the other songs to get 16 songs a day
B- the weekend has 2 days in it so you would just multiply 16 x 2 which gives you 32
A store at the mall was closing. Everything in the store was 75% off. If you
wanted to buy a $200 jacket, how much did it actually cost you?
Answer:
50 dollars
