Answer:
part 1: Jessica saved 100, Raphael saved 88
part 2: The rate at which Jessica is adding to her savings each week is $4 more than the rate at which Raphael is adding to his savings each week.
Step-by-step explanation:
First figure out how much money Jessica saved at the end of week 8, compared to Raphael.
Use x =8
y = 10*8 + 20 = 100
For Raphael it is shown in the table as 88.
Next figure out the rate Raphael saves. We can find the slope usng (y2-y1) / (x2-x1).
Using the table lets use (0,40) and (1,46)
46-40 / 1-0 = 6/1 = 6
So Raphael saves $6 each week. This is $4 less than what Jessica saves each week since the slope for her equation is 10 or $10 each week.

Answer:
A. (-2, -4)
Step-by-step explanation:
Substitution Method
3x + 2 = -2x - 8
5x = -10
x = -2
y = 3x + 2
y = 3 (-2) + 2
y = -4
(x, y) = (-2, -4)

Taylor earned the following amount each day.
• one dollar of the first day
• three dollars on the second day
• nine dollars on the third day
• twenty-seven dollars on the fourth day
Which function represents Taylor's daily earnings as a function of the number of days, t?
A f(x) = 3+1
B f(x) = 3
f(x) = 3t
D f(x) = 3-1
Answer:
f(t) = 3^(t - 1)Step-by-step explanation:
one dollar of the first day = 3^0three dollars on the second day = 3^1 nine dollars on the third day = 3^2twenty-seven dollars on the fourth day = 3^3Numbers increase 3 times a day, it is an exponential function, powers of 3
The function is going to be:
f(t) = 3^(t - 1)Options are not clear, it seems to be D

Can somebody help me with this question, please? I have no idea how to do this or find the answer. :/ How many ways are there to choose a number from the set {−96, −48, −42, −36, −18, −14, −6, 14} that is divisible by either 6 or 8?
Answer:
28 different ways
Step-by-step explanation:
This is a combination question. Combination has to do with selection.
Total number of element in the set = 8
Number divisible by 6 or 8 are {-98, -48, -42, -36, -18, -6}
Total number divisible by 6 or 8 is 6
The number of ways we can choose 6 items from 8 is expressed as;
8C6 = 8!/(8-6)!6!
8C6 = 8!/(2)!6!
8C6 = 8*7*6!/2!6!
8C6 = 8*7/2
8C6 = 56/2
8C6 = 28 ways
Hence there are 28 different ways

the vertices of parallelogram abcd are A(4,0,3), B(3,4,-2),C(-2,0,1). find the coodrdinates of fourth vertices
Given :
The vertices of parallelogram ABCD are A(4,0,3), B(3,4,-2),C(-2,0,1).
To Find :
The coordinates of fourth vertices.
Solution :
We know, the vertices are ABCD .
Let, point D is (x,y,z) .
Also, diagonals of a parallelogram bisect each other.
Let, point of intersection of daigonal is O.
Coordinates of O are :
[tex]O_x = \dfrac{4+(-2)}{2}= 1\\\\O_y = \dfrac{0+0}{2 } = 0 \\\\O_z = \dfrac{3+1}{2}= 2[/tex]
O(1,0,2)
Value of point O through BD.
[tex]O_x = \dfrac{3+x}{2}\\\\x=-1\\\\O_y = \dfrac{4+y}{2}\\\\y = -4\\\\O_z= \dfrac{-2+z}{2}\\\\z = 6[/tex]
Therefore, the fourth vertices is D( -1,-4,6 ).

David expressed the ratio of the number of books that he owns to the number of DVDs that he owns as 27:11. Which statement could be true based upon this relationship? David has 11 books and 27 DVDs. David has 11 DVDs and 27 books. David has 11 DVDs and 27 items total. David has 11 books and 27 items total.
Answer: David has 11 DVDs and 27 books.
Step-by-step explanation:
When numbers are put in ratio form they are meant to compare their relative sizes.
The first number will be the first item being compared to the other.
For instance, if you had 2 pens and 3 pencils, the ratio of your pens to your pencils will be; 2:3. The ratio of your pencils to your pens however is 3:2.
In the same vein, a ratio of books to DVDs of 27:11 means that David has 27 books and 11 DVDs.
Answer:
David has 11 DVDs and 27 books.

22=-2x+4(-4x-17)
solve for x pls
Answer:
x=-5
Step-by-step explanation:
22=-2x+4(-4x-17)
We move all terms to the left:
22-(-2x+4(-4x-17))=0
We calculate terms in parentheses: -(-2x+4(-4x-17)), so:
-2x+4(-4x-17)
We multiply parentheses
-2x-16x-68
We add all the numbers together, and all the variables
-18x-68
Back to the equation:
-(-18x-68)
We get rid of parentheses
18x+68+22=0
We add all the numbers together, and all the variables
18x+90=0
We move all terms containing x to the left, all other terms to the right
18x=-90
x=-90/18
x=-5
Answer:
Step-by-step explanation:
22 = -2x + 4(-4x - 17)
22 = -2x + 4*(-4x) - 4*17
22 = -2x - 16x - 68 {Combine like terms}
22 = -18x - 68 {Add 68 to both sides}
22 + 68 = -18x
90 = -18x {Divide both sides by (-18)
90/-18 = x
x = -5
A student solved z + (-0.72) = -2.5 for z using the
following steps.
Step 1: Z + (-0.72) + (-0.72) = -2.5+ (-0.72)
z = -2.5+ (-0.72)
Step 2:
Step 3:
z = -3.22
What was the student's error?
Answer:
Mistake in step1Step-by-step explanation:
Given
z + (-0.72) = -2.5Solving in steps
1. ⇒ z + (-0.72) - (-0.72) = -2.5 - (-0.72)2. ⇒ z = - (2.5 - 0.72)3. ⇒ z = - 1.78The student's mistake was adding (-0.72) instead of - (-0.72) or 0.72
Answer:
To solve, you must use the inverse operation. In step 1, -0.72 should have been subtracted from both sides, not added. Otherwise, 0.72 should have been added to both sides, not -0.72.
