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
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.

The graph below shows a system of equations:
The x-coordinate of the solution to the system of equations is
Answer:
solution is (-2, 2) so x-coordinate of solution is -2
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
First, we have to write down both equations.
y = x + 4
3y = -2x + 2
Now we already have an equation that we can plug into the other equation.
= 3(x + 4) = -2x + 2
= 3x + 12 = -2x + 2
= 5x + 12 = 2
= 5x = -10
x = -2
Now we know that x = -2, and the question asks for the x-coordinate, which is -2.

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

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

what is the slope of 4x + 4y = 8?
Answer:
m=-1
Step-by-step explanation:
4x-8=-4y
x-2=-y
-x+2=y
Answer:
m=-1
Step-by-step explanation:
It is easiest to put the equation into slope-intercept form first.
4x+4y=8
4y=-4x+8
y=-x--2

A line that passes through the point -4, -3 and 2,6
Answer:
The equation is;
2y = 3x + 6
Step-by-step explanation:
We start by calculating the slope of the line
m= y2-y1/x2-x1
m = (6+3)/(2+ 4) = 9/6 = 3/2
The point slope form would be;
y-y1 = m(x-x1)
Let us use the point (-4,-3)
Thus, we have
y + 3 = 3/2(x+ 4)
2y + 6 = 3x + 12
2y = 3x + 12-6
2y = 3x + 6

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

x = -2
y = 3x + 2
y = 3 (-2) + 2
y = -4
(x, y) = (-2, -4)

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 ).

In the first 8 overs the bowling rate of a cricketer is 4.5, In the last two over by giving how much run the bowling rate will be 5?
Answer:
In the last two overs, the bowler gave 14 runs.
Step-by-step explanation:
The bowling rate of 4.5 in the first 8 over means he gave 32.5 runs.
i.e.
Score given in first 8 overs = 4.5 × 8 = 36
Given that the bowling economy 5 at the end of 10 overs means the bowler must have given 10 × 5 = 50 score in the total 10 overs.
so, subtract 36 from 50 to get the score he will be giving in the last two overs.
i.e. score given the last two overs = 50 - 36 = 14
Therefore, in the last two overs, the bowler gave 14 runs.
