Answer:
X= -2
Step-by-step explanation:
Given: 16 = -4(x - 1) + 4
Solution:
Subtract 4 from both sides
12 = -4(x -1)
Divide -4 on both sides
-3 = x - 1
Add -1 on both sides
x = -2

Which number is the same distance from 0 on a number line as 3/2 answers -3 -3/2 -2/3 2/3 3
Answer: -3/2

To find its distance away from 0, then just find its opposite.
On the number line if you graph 3/2, its opposite will be -3/2
Problem 1: Solve the systems of equations by the method of your choice.
2x+y=5
x-y=1
Problem 2: The difference of two complementary angles is 30 degrees. Set up a system of linear equations that would find the angles. Do not solve the system.
Problem 3: A cashier has 30 bills, all of which are $10 or $20 bills. The total value of the money is $460. Set up a system of linear equations that would find how many of each type of bills the cashier has. Do not solve the system.
Problem 4: Give an example of a system of linear equations that has no solutions. Explain how can you decide the number of solutions without solving the system.
Answer:
x=2 and y=1
Step-by-step explanation:
2x+y=5
x-y=1
buy adding both equations we get
3x=6
x=2 ( divide 3 on both sides)
put x=2 in any equation
2-y=1
y=2-1
y =1
p2
Problem#2
Let say two complementary angles are A & B
difference of two complementary angles is 30°
=> A - B = 30
Sum of two complementary angles is 90°
=> A + B = 90
Hence A = 60° , B = 30°
Problem#3
Total bill = 30
$ 10 Bills = A
$ 20 Bills = B
10 * A + 20* B = 460
A + B = 30
A = 14 , B = 16
Problem#4
4x+2=y
2y−8x=10
The first step is to simplify the second equation into

y=4x+5
Now, the two equations are:
y=4x+2
y=4x+5

What is the surface area of a cube with side length 3/2 units?
Answer:
Surface area = 13.5 unit square.
Step-by-step explanation:
We have given the side length of cube = 3/2 units
Now we have to find the surface area of the cube by using the given information. Therefore we must use the below formula to find the surface area. the formula is as follows:
Surface area = 6 (side)^2
Now plug the given information in the formula.
Surface area = 6 (3/2)^2
Surface area = 13.5 unit square.
What is the polynomial function of least degree whose only zeros are -4,2, and 3?
Answer:
never heard about it
Step-by-step explanation:
The distance between the point (2,1,1) and the plane x-2y=5 is
The given plane has normal vector
[tex]x-2y=5\implies\mathbf n=\langle1,-2,0\rangle[/tex]
Scaling n by a real number t gives a set of vectors that span an entire line through the origin. Translating this line by adding the vector <2, 1, 1> makes it so that this line passes through the point (2, 1, 1). So this line has equation
[tex]\mathbf r(t)=\langle1,-2,0\rangle t+\langle2,1,1\rangle=\langle 2+t, 1-2t, 1\rangle[/tex]
This line passes through (2, 1, 1) when t = 0, and the line intersects with the plane when
[tex]x-2y=5\implies(2+t)-2(1-2t)=5\implies5t=5\implies t=1[/tex]
which corresponds the point (3, -1, 1) (simply plug t = 1 into the coordinates of [tex]\mathbf r(t)[/tex]).
So the distance between the plane and the point is the distance between the points (2, 1, 1) and (3, -1, 1):
[tex]\sqrt{(2-3)^2+(1-(-1))^2+(1-1)^2}=\boxed{\sqrt5}[/tex]

If you earned 892.50 after depositing 1400 at 4.25% simple interest, how long was it invested ? Using the simple interest formula, solve for t. Formula I=Prt
Answer:
Time t = 15 years
Step-by-step explanation:
Interest = 892.50
Principal = 1400
Rate = 4.25%
Time = unknown
But
interest I = Principal p * rate r * time t
Time t = interest I/(principal P * rate r)
Time t=( 892.50*100)/(1400*4.25)
Time t=89250/5950
Time t = 15 years
The table shown classifies the 35 students in a
college statistics course by year (1st, 2nd, 3rd, 4th)
and type of major (Humanities, Sciences, Other). A
student from this course will be selected at random.
What is the probability that the student's major is
Humanities?
The correct answer is 0.45 or 45%
Explanation:
In this case, the probability of selecting a student whose major is Humanities can be calculated by finding the number of Humanities students, which is considered as the desired outcome, and dividing this by the total of outcomes or students. The process to find the probability is shown below:
[tex]P = \frac{Desired outcomes}{Total outcomes}[/tex]
[tex]P= \frac{Students from Humanities}{Total students}[/tex]
[tex]Students of Humanities = 5 + 5 + 3 + 3 = 16 students[/tex] (Add the students of each year that are part of Humanities)
[tex]Total of students = 35[/tex] (This number is provided in the question but can also be found by adding all numbers in the table)
[tex]P = \frac{16}{35}[/tex]
[tex]P = 0.45[/tex]
Multiply the probability by 100 to know its equivalent in percentages 0.45 x 100 = 45. This means the probability that a student of humanities is selected is 0.45 or 45%.

Answer:
Points P ( 4 , - 7 ) and Q ( 1 , 5 ) belong to the equations:
1 ; 4 ; and 5
Step-by-step explanation:
Equations 1 ; 4 and 5 are the same equation
Equation 1 y = - 4*x + 9
Equation 4
y + 7 = - 4 * ( x - 4 ) ⇒ y + 7 = - 4*x + 16 ⇒ y = - 4*x - 7 + 16
y = -4*x + 9
Equation 5
4*x + y = 9 ⇒ y = - 4*x + 9
Now for the equation y = - 4*x + 9
P ( 4 , -7)
For x = 4 y = - 4*(4) + 9 ⇒ y = - 16 + 9 ⇒ y = - 7
Then point P is in the line y = - 4*x + 9
Point Q (1 , 5 )
For x = 1 y = - 4 * ( 1) + 9 ⇒ y = - 4 + 9 ⇒ y = 5
Point Q is in the line y = - 4*x + 9
Equation 2
y = - 4*x - 23
Point P ( 4 , - 7 )
For x = 4 y = 16 - 23 y = - 7
Point P is in the line
Point Q
For x = 1 y = - 4 *(1) - 23 ⇒ y = - 27
Then poin Q is not in the line
Equation 3
y - 1 = - 4 * ( x - 4 )
y - 1 = -4*x + 16 ⇒ y = - 4*x + 17
Point P ( 4 , - 7 )
For x = 4
y = - 16 + 17 ⇒ y = 1
Point P is not in the line
And Point Q ( 1 , 5 )
For x = 1
y = - 4* ( 1 ) + 17 ⇒ y = 13 Q is not in the line

Josh has 212 marbles. Peck has 314 marbles. Round each number to the nearest hundred. Then, type how much marbles more does Peck have.
Round each number to the nearest hundred.
212 = 200.
314 = 300.
How much more marbles does Peck have?
314 - 212 = 102.
That is your answer. Hope this helps!
Answer:
100 more marbles
Step-by-step explanation:
So first let's round the numbers to the nearest hundred. So 212 rounds to 200, and 314 rounds to 300. Then we do 300-200 and get 100. SO the answer is 100.
A piece of carpet is 360 cm long. Mr. Smith cuts it into three pieces in the ratio 2:3:4. Workout the length of the longest piece of carpet.
Answer:
The longest length of carpet is 160 cm.

Next, you have to find the length of carpet in 4 ratio as the question wants the longest length :
[tex]4 \: units = 40 \: cm \times 4[/tex]
[tex]4 \: units = 160 \: cm[/tex]
Answer:

Which theorem can be used to show that △JKL ~ △MNP?
In this case the answer would be the last option
because it is shrunk by 2/3 on just the x side
D is the only one who has that first transformation
By a theorem of similarity, it can be shown that △JKL ~ △MNP.
What is the similarity?Similar figures are those figures which are identical in shape, but not necessarily in size.
Two squares with sides of 10 and 5 are similar because their shape is exact but the size is different.
Another example is all circles are similar circles.
The ratio of corresponding sides of similar objects is always the same.
Any two triangles will be similar if the ratio of their corresponding side is same.
If △JKL ~ △MNP then their corresponding side ratio will definitely same.
If corresponding side is same order in JKL and MNP then,
JK/KL = MN/NP
Hence "By a theorem of similarity, it can be shown that △JKL ~ △MNP".

The expanded form for 300684 can be written with only 4 add ends. Explain how this is possible for a number with 6 digits
Answer:
This can be because our number, 300,684, has only four digits different than zero.
Then we can write this number as:
300,684 = 300,000 + 600 + 80 + 4.
So we add only 4 terms.
So when we write a number in this form, we will have the same numbers of terms in the addition that the number of digits different than zero in our original number.
