Which best describes the transformation from the graph of f(x) = x2 to the graph of
f(x) = (x – 3)2 – 1?
left 3 units, down 1 unit
left 3 units, up 1 unit
right 3 units, down 1 unit
right 3 units, up 1 unit
Answer: Third option.
Step-by-step explanation:
These are some transformations for a function f(x):
If [tex]f(x)-k[/tex], then the function is shifted down "k" units.
If [tex]f(x-k)[/tex], then the function is shifted right "k" units.
Knowing this we can describe the transformation from the graph of the function [tex]f(x) = x^2[/tex] to the graph of the function [tex]f(x) = (x - 3)^2-1[/tex]. This is:
The function [tex]f(x) = (x - 3)^2-1[/tex] is the function [tex]f(x) = x^2[/tex] but shifted right 3 units and shifted down 1 units.
Therefore, the correct option is the third one.
Answer:
right 3 units, down 1 unit
Write the linear Inequality shown in the graph. The gray area represents the shaded region.
ANSWER
[tex]y \leqslant - x + 4[/tex]
EXPLANATION
The equation of the boundary line is
[tex]y = - x + 4[/tex]
Hence the inequality is either
[tex]y \leqslant - x + 4[/tex]
or
[tex]y \geqslant - x + 4[/tex]
We test the origin to get determine which one represents the shaded
We substitute (0,0) into the first inequality to get;
[tex]0\leqslant - (0) + 4[/tex]
This implies that,
[tex]0 \leqslant 4[/tex]
Hence the correct answer is
[tex]y \leqslant - x + 4[/tex]
Answer: Second Option
[tex]y \leq -x +4[/tex]
Step-by-step explanation:
The region is bounded by a line of negative slope that cuts the y-axis at the point y = 4 and cuts the x-axis at the point x = 4.
So the equation of this line is
[tex]y = -x + 4[/tex]
If the region is composed of all the points that lie below the line y = -x + 4 then it means that the region is formed by all the values of y less than or equal to the line [tex]-x + 4[/tex].
Therefore the inequation is:
[tex]y \leq -x +4[/tex]

Irina had $300 and then earned $50 each week for 3 weeks. Last week, she bought groceries for $37 and two $25 gift
cards. How much money does she have left?
A.$63
B.$363
C.$578
D.$3,889
Answer:
B)$363
Step-by-step explanation:
since she earned $50 each week
50x3=150
then plus the $300 she has
300+150= 450
then add the groceries and two $25 gifts
25x2=50
37+50=87
then take that away from the amount of money she has
450-87=363
Irina has $63 left.
Explanation:To calculate how much money Irina has left, we need to follow these steps:
Start with $300, which is her initial amount.Add $50 for each of the 3 weeks she earned money. $50 + $50 + $50 = $150.Subtract the amount she spent on groceries and gift cards from the total amount she earned. $150 - $37 - $25 - $25 = $63.Therefore, Irina has $63 left.

Which number sentence does the following number line represent?
0-4+7= 3
3+(-4)=-7
04+3=7
3+(-7)=-4
Answer:
Last option: [tex]3+(-7)=-4[/tex]
Step-by-step explanation:
The number line can help us to make additions and subtractions.
To add a positive number we need to move the point to the right and to add a negative number we need to move the point to the left.
You can observe in the figure that the point on the number line is moved from 3 to -4, then it is moved 7 places to the left. Therefore, you can express it in the following form:
[tex]3+(-7)[/tex]
This is:
[tex]3+(-7)=3-7=-4[/tex]

A rock dropped on the moon will increase its speed from 0 m/s (its starting
speed) to 8.15 m/s in about 5 seconds. If you were standing on the moon,
measuring the rock's motion, what would you measure for the magnitude of
its acceleration?
O
A. 8.2 m/s2
O B. 41 m/s2
O C. 9.8 m/s2
O D. 1.63 m/s2
The answer is:
The correct option is the option D
[tex]g=1.63\frac{m}{s^{2}}[/tex]
Why?To calculate the acceleration, we need to use the following formula that involves the given information (initial speed, final speed, and time).
We need to use the following free fall equation:
[tex]V_{f}=V_{o}-g*t[/tex]
Where:
[tex]V_{f}[/tex] is the final speed.
[tex]V_{o}[/tex] is the initial speed.
g is the acceleration due to gravity.
t is the time.
We are given the following information:
[tex]V_{f}=8.15\frac{m}{s}[/tex]
[tex]V_{o}=0\frac{m}{s}[/tex]
[tex]t=5seconds[/tex]
Then, using the formula to isolate the acceleration, we have:
[tex]V_{f}=V_{o}-g*t[/tex]
[tex]V_{f}=V_{o}-g*t\\\\g*t=V_{o}-V_{f}\\\\g=\frac{V_{o}-V_{f}}{t}[/tex]
Now, substituting we have:
[tex]g=\frac{V_{o}-V_{f}}{t}[/tex]
[tex]g=\frac{0-8.15\frac{m}{s}}{5seconds}=-1.63\frac{m}{s^{2}}[/tex]
Therefore, since we are looking for a magnitude, we have that the obtained value will be positive, so:
[tex]g=1.63\frac{m}{s^{2}}[/tex]
Hence, the correct option is the option D
[tex]g=1.63\frac{m}{s^{2}}[/tex]

find the solution of this system of equations x=4+y -10x+6y+-28 separate x and y values with a comma.
ANSWER
The solution is (1,-3)
EXPLANATION
The system of Equations are;
[tex]x=4+y[/tex]
and
[tex]-10x+6y=-28[/tex]
We substitute the first equation into the second equation to get:
[tex]-10(4 + y)+6y=-28[/tex]
We expand the parenthesis to get:
[tex]-40 - 10y+6y=-28[/tex]
Group similar terms to get:
[tex]- 10y+6y=-28 + 40[/tex]
Simplify the similar terms to get;
[tex] - 4y = 12[/tex]
Divide both sides -4.
[tex]y = \frac{12}{ - 4} [/tex]
[tex]y = - 3[/tex]
We put y=-3 into the first equation to get:
[tex]x = 4 + - 3 = 1[/tex]
Therefore the solution is (1,-3)

Answer:
6/7.
Step-by-step explanation:
The sum of the 2 numbers is greater than 5 in 6 out of 7 throws.
So the required experimental probability is 6/7.
Answer:
The experimental probability that the sum of the next two number rolled is more than 5 is [tex]\frac{6}{7}[/tex].
Step-by-step explanation:
From the given table it is clear that
Roll 1 : 6+6=12>5
Roll 2: 6+1=7>5
Roll 3: 3+5=8>5
Roll 4: 6+2=8>5
Roll 5: 6+4=10>5
Roll 6: 5+1=6>5
Roll 7: 3+2=5
There is information about 7 roll, therefore the total possible outcomes is 7.
6 out of seven rolls resulted in a sum greater than 5, therefore the favorable outcomes is 6.
The experimental probability that the sum of the next two number rolled is more than 5 is
[tex]P=\frac{\text{Favorable outcomes}}{\text{Total possible outcomes}}[/tex]
[tex]P=\frac{6}{7}[/tex]
Therefore the experimental probability that the sum of the next two number rolled is more than 5 is [tex]\frac{6}{7}[/tex].

Answer:
his total income by the end of 4 years will be: $2622.
Step-by-step explanation:
A man earns a base salary of $2000, and every year he got a raise of 7% on his total income.
The first year, he will earn: 1.07($2000) = $2140
The second year he will earn: 1.07($2140) = $2289.8
The third year he will earn: 1.07($2289.8) = $2450.086
The fourth year he will earn: 1.07($2450.086) = $2621.59202
Therefore, his total income by the end of 4 years will be: $2622.
Using the given points, determine the delta symbol y. (-3,-5) and (0,10)
Answer:
Δy = 15
Step-by-step explanation:
Δy represents the change in the y-coordinates
We are given points (-3,-5) and (0,10)
here y₁ = -5 and y₂ = 10
so, delta y will be
Δy = y₂ - y₁
Δy = 10 -(-5)
Δy = 10 + 5
Δy = 15
So, delta y Δy =15
There are 85 apples on the big tree, John picked out 15%. How many did John pick out?

Evaluate the following expression for d=-5 and w=6
[tex] \frac{d {}^{0} }{w {}^{ - 3} } [/tex]
A. -23
B. 1/216
C. 216
D. -18
Answer:
216
Step-by-step explanation:
Anything to the zero power is equal to 0.
The denominator can be moved to the numerator because the exponent is negative. So it is now 1*6^3. This is equal to 216.
The value of expression [tex]\frac{d^{0} }{w^{-3} }[/tex] is 216
The correct option is (B).
What is exponents and power?Power can be defined as an expression that represents repeated multiplication of the same number whereas exponent is the quantity that represents the power to which the number is raised.
Given:
[tex]\frac{d^{0} }{w^{-3} }[/tex]
put d=-5 and w=6
So, [tex]\frac{-5^{0} }{6^{-3} }[/tex]
=1/[tex]6^{-3}[/tex] [a°=1]
=6³ [[tex]1/a^{-b} = a^{b}[/tex]]
=216.
hence, [tex]\frac{d^{0} }{w^{-3} }[/tex] = 216.

Answer:
3/2
Step-by-step explanation:
(2x² − 3x)² + 4 (2x² − 3x) + 3 = 0
We can simplify this using substitution. Let's say that u = 2x² − 3x.
u² + 4u + 3 = 0
Factoring:
(u + 3)(u + 1) = 0
u = -3, u = -1
Therefore:
2x² − 3x = -3, 2x² − 3x = -1
2x² − 3x + 3 = 0, 2x² − 3x + 1 = 0
For a quadratic ax² + bx + c = 0, the sum of the roots is -b/a. So in both cases, the sum is 3/2.
