Z-49+851=100+21z /////////////////////////////////////////////////
Answer:
z=35.1
Step-by-step explanation:
Answer:
z = 351/10 or z = 35.1
Step-by-step explanation:
*Add/subtract numbers: -49 + 851 = 802
z + 802 = 100 + 21z
*Subtract 802 from both sides
z + 802 - 802 = 100 + 21z - 802
*Simplify
z = 21z - 702
*Subtract 21z from both sides
z - 21z = 21z - 702 - 21z
*Simplify
-20z = -702
*Divide both sides by -20
- 20z/20 = - 702/- 20
*Simlify
z = 351/10 or z = 35.1

Step-by-step explanation:
Mike and Lilly are working together on a science project. They agreed to
meet halfway between their houses and ride their bikes to the library
together. Approximately how far will Mike and Lilly ride to the library once
they meet each other at the halfway point?
The approximate distance Mike and Lilly will have to travel between halfway point and Library is 7.8 miles.
From the graph :
Mike's coordinate = (-4, 2) Lilly's coordinate = (2, - 2) Library coordinate = (4, 6)Meeting point = Halfway point :
(x1 + x2) /2 ; (y1 + y2) / 2
X - coordinate = (-4 + 2) / 2 = - 2/ 2 = - 1
Y - coordinate = (2 + (-2)) /2 = 0/2 = 0
Hence, meeting point = (-1, 0)
The distance between meeting point and library :
Distance = √[(x2 - x1)² + (y2 - y1)²]
Distance = √[(4 - (-1))² + (6 - 0)²]
Distance = √(25 + 36)
Distance = √61 = 7.8 miles
Therefore, the distance between halfway point and library ls approximately 7.8 miles

Step-by-step explanation:
going left and right changes the x( first number in each parentheses)
going up and down changes the y (second number in parentheses)
going to the left by 9 means all the first numbers are going in the negative direction (-9)
going up by 12 means the second numbers are going in the positive direction (+12)
take all x values and add -9, take all y values and add 12

Answer:
D) -2.14< root10 <|-2.8|
Step-by-step explanation:
the value for -2.14 is as plain as you can see, the negative version of 2.14.
The square root of 10 is 3.16227766.
The lines next to -2.8 is asking for the absolute value of -2.8, or the distance between that number and zero. The distance between -2.8 and 0 is positive 2.8, because distance can't be negative.
The 3 numbers taken from the explanations are -2.14, 3.16, and 2.8. Ranking them from least to greatest would give you -2.14, 2.8, 3.16, or -2.14< root10 <|-2.8|

Answer:
1) 350
2) 195.83
Step-by-step explanation:
#1.Tuition fee = $12, 000 per year.
30% of it's being paid off by the scholarship, so she'll have to pay:
[tex] = 12000 - ( \frac{30}{100} \times 12000) [/tex]
[tex] = 12000 - 3600[/tex]
[tex] = 8400[/tex]
She'll have to pay $ 8400 by herself, her savings.
If she's saving $ 8400 for two years, she's actually saving $ 8400 for 24 months!
for one month, it'll be
= 8400/ 24
= $ 350 per month
#2one year fee = $ 10, 700
uncle pays half of it, I.e., 10700/ 2
= $ 5, 350
he gets a grant for $ 3,000
so, the part of the fee he ain't paying
= 5,350 + 3000
= $ 8,350
So, he'll have to save:
= 10,700 - 8,350
= $ 2,350
that is per year,
for per month = 2350/ 12
= $ 195.83
How many points of intersection are there between the graphs of the hyperbola and ellipse?
3x2 – 4y2 + 4x – 8y +4= 0
3x2 + y2 + 4x – 3y +4= 0
A.0
B. 1
C. 3
D.4
The point of intersection is the point where two or more functions meet.
The graphs of the hyperbola and ellipse have 0 point of intersection
The given parameters are:
[tex]\mathbf{3x^2 - 4y^2 + 4x - 8y + 4 = 0}[/tex]
[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 0}[/tex]
To determine the points of intersection, we simply equate both equations.
So, we have:
[tex]\mathbf{3x^2 + y^2 + 4x - 3y + 4 = 3x^2 - 4y^2 + 4x - 8y + 4 }[/tex]
Cancel out the common terms
[tex]\mathbf{y^2 - 3y = - 4y^2 - 8y }[/tex]
Collect like terms
[tex]\mathbf{y^2 +4y^2= 3y - 8y }[/tex]
[tex]\mathbf{5y^2= - 5y }[/tex]
Divide through by 5
[tex]\mathbf{y^2= - y}[/tex]
Divide through by y
[tex]\mathbf{y= -1}[/tex]
The system of equation does not give room to calculate the x-coordinate at the x-axis.
Hence, the graphs of the hyperbola and ellipse have 0 point of intersection

|8w+5|=21
please show work
Answer:
w=-13/4
w=2
Step-by-step explanation:
|8w+5|=21
Step by step solution :
STEP
1
:
Rearrange this Absolute Value Equation
Absolute value equalitiy entered
|8w+5| = 21
STEP
2
:
Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |8w+5|
For the Negative case we'll use -(8w+5)
For the Positive case we'll use (8w+5)
STEP
3
:
Solve the Negative Case
-(8w+5) = 21
Multiply
-8w-5 = 21
Rearrange and Add up
-8w = 26
Divide both sides by 8
-w = (13/4)
Multiply both sides by (-1)
w = -(13/4)
Which is the solution for the Negative Case
STEP
4
:
Solve the Positive Case
(8w+5) = 21
Rearrange and Add up
8w = 16
Divide both sides by 8
w = 2
Which is the solution for the Positive Case
STEP
5
:
Wrap up the solution
w=-13/4
w=2

The total cost in dollars, c, to purchase video games online can be found using e function c = 16.95x + 4.75, where x is the number of video games purchased. If at least 4 games but no more than 7 games are purchased online, what is the range of the function for this situation?
Answer:
72.55 ≤ x≤ 123.40
Step-by-step explanation:
c = 16.95x + 4.75,
We have to purchase a minimum of 4 games
Let x = 4
c (4) = 16.95(4) + 4.75
c(4) =67.8+4.75 = 72.55
This is the smallest amount we will spend
The most we will purchase is 7 games
Let x = 7
c (7) = 16.95(7) + 4.75
c(7) =118.65+4.75 = 123.40
This is the largest amount we will spend
The range is
72.55 ≤ x≤ 123.40

Heather invest $3377 in a retirement account with a fixed annual interest rate of 8% compounded two times per year .how long will it take for the countdowns to reach $14,989.87?
round to the nearest whole year.
It will take 19 years for the countdowns to reach $ 14,989.87
Given that Heather invest $ 3377 in a retirement account with a fixed annual interest rate of 8% compounded two times per year, to determine how long will it take for the countdowns to reach $ 14,989.87 the following calculation must be performed:
Initial value x (1 + interest rate / compounding times) ^ (years x compounding times) = Compound interest
3377 x (1 + 0.08 / 2) ^ 2X = 14,989.87 3377 x 1.04 ^ 2X = 14,989.87 3512.08 ^ 2X = 14,989.87 X = 19
Therefore, it will take 19 years for the countdowns to reach $ 14,989.87.

7 divided by 55, but every step must be show
Answer:
Step 1:
Start by setting it up with the divisor 7 on the left side and the dividend 55 on the right side like this:
7 ⟌ 5 5
Step 2:
The divisor (7) goes into the first digit of the dividend (5), 0 time(s). Therefore, put 0 on top:
0
7 ⟌ 5 5
Step 3:
Multiply the divisor by the result in the previous step (7 x 0 = 0) and write that answer below the dividend.
0
7 ⟌ 5 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (5 - 0 = 5) and write the answer below.
0
7 ⟌ 5 5
- 0
5
Step 5:
Move down the 2nd digit of the dividend (5) like this:
0
7 ⟌ 5 5
- 0
5 5
Step 6:
The divisor (7) goes into the bottom number (55), 7 time(s). Therefore, put 7 on top:
0 7
7 ⟌ 5 5
- 0
5 5
Step 7:
Multiply the divisor by the result in the previous step (7 x 7 = 49) and write that answer at the bottom:
0 7
7 ⟌ 5 5
- 0
5 5
4 9
Step 8:
Subtract the result in the previous step from the number written above it. (55 - 49 = 6) and write the answer at the bottom.
0 7
7 ⟌ 5 5
- 0
5 5
- 4 9

You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
