Step-by-step explanation:
5 − 3x = −7
=> 5 + 7 = 3x
=> 12 = 3x
[tex] = > x = \frac{12}{3} [/tex]
=> x = 4 (Ans)
Given :
5 − 3x = −7⠀
To Find :
The required value of x .⠀
Solution :
[tex]\qquad \sf \: { \dashrightarrow 5 - 3x = - 7}[/tex]
⠀
Adding (–5) to both sides :
[tex]\qquad \sf \: { \dashrightarrow 5 + ( - 5) \: − 3x = −7 + ( - 5)}[/tex]
[tex]\qquad \sf \: { \dashrightarrow \: − 3x = - 12}[/tex]
⠀
Dividing both sides by 3 :
[tex]\qquad \sf \: { \dashrightarrow \dfrac{ - 3x}{3} = \dfrac{ - 12}{3} } [/tex]
[tex]\qquad \sf \: { \dashrightarrow − x = −4}[/tex]
⠀
Cancelling (–) from both sides we get :
[tex]\qquad {\pmb {\bf{ \dashrightarrow x = 4}}} \\ [/tex]
⠀
Therefore, The required value of x is 4.

sarah has 214 bag of beads each bag has enough beads for 22 bracelets she estimates that since 200x 20 =4,000 there are enough beads for aT LEAST 4000 bracelets tell how how you can critique sarahs reasoning
Answer:
Sarah's reasoning sounds good to start. She rounded the available bags and their content, so the result, 4000 bracelets, should be really easy to reach.
The exact numbers are 214 bags * 22 bracelets / bag = 4708 bracelets; so as you see, Sarah took care of having room to loose some beads and yet the beads will be enough to make 4000 bracelets.
Of course, if you want to be sure, you should ask Sarah some questions. For example:
1) What proportion of beads are normally deffective?
2) What proportion of beads are normally lost when crafting?
So, if Sarah did not take into account those proportions she migth be overestimating the number of bracelets they can make.
Sarah's assumptions of having enough beads for at least 4000 bracelets is correct.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Sarah who has 214 bag of beads each bag has enough beads for 22 bracelets
According to Sarah, there are enough beads for at least 4000 bracelets.
Mathematically -
x[e] ≥ 4000
Actual number of beads she could make = 22 x 214 = 4708 = x[a]
Since, x[a] > x[e], we can say that Sarah's assumptions are correct.
Therefore, we can say that Sarah's assumptions are correct.

what is the square of 8
Answer:
Your square would be 64.
Step-by-step explanation:
If you think about if 8 is a square root of a number, the answer is yes. It's 64. When you multiply numbers by themselves, such as 2*2, or 8*8, you get their square. In this case, 8*8 is equal to 64. I hope this helps you. : )

Factoring with Diagrams
A(x) = x3 – 7x² – 16x +112, You know that
(x-7) is a factor.
x-
х
+3
-7
-72
Check your work
Write A(x) as the product of linear factors.
Answer:
(x - 7)(x - 4)(x + 4).
Step-by-step explanation:
A(x) = x3 – 7x² – 16x +112
Dividing by x-7:
x^2 - 16 <-------- Quotient
-----------------------------
x-7)x^3 - 7x^2 - 16x + 112
x^3 - 7x^2
0 - 16x + 112
- 16x + 112
..............
so A(x) = (x - 7)(x^2 - 16) x^2 - 16 is the difference of 2 squares so we have:
(x - 7)(x - 4)(x + 4).
Checking by expanding the brackets:
(x - 7)(x - 4)(x + 4)
= x(x - 4)(x + 4) - 7(x - 4)(x + 4)
= x(x^2 - 16) - 7(x^2 - 16)
= x^3 - 16x - 7x^2 + 114
= x^3 - 7x^2 - 16x + 112

Answer:
x = 6
Step-by-step explanation:
because of the exterior angle theorem, instead of looking for the inner angle's amount, I can directly look for the other angle's amount.
so:
6x + 8 + 5x + 8 = 82
11x + 16 = 82
11x = 66
x = 6

y = 1.5x + 9
(y = height; x = number of cups)
Step-by-step explanation:
let x = number of cups
let y = height of the stack
the first cup will add 9 to the height (7.5 + 1.5)
so 9 is the y-intercept
for each additional cup, 1.5 will be added
so y = 1.5x + 9

the answer is -1
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
The input value for which f(x) = g(x) is true is -1
The formula for calculating the equation of a line is expressed as:
m is the slope
b is the y-intercept
For table 1,
Get the slope:
Use the coordinate (-2, 3) and m = 0 to get the value of "b"
The required function for table 1 is f(x) = 3
For table 2:
Get the slope:
Use the coordinate (-2, 4) and m = -1 to get the value of "b"
The required function for table 2 is g(x) = -x + 2
If the function f(x) = g(x), hence:
-x + 2 = 3
-x = 3 - 2
-x = 1
x = -1
Hence the input value for which f(x) = g(x) is true is -1

Answer number 8 thank you(;´༎ຶٹ༎ຶ`)
Answer:
a. Rosemarie has 16 grandchildren.
b. Each grandchild would receive $0.50 or 50 cents.
Step-by-step explanation:
a. There are 4 sons, and each son has 4 children.
Son 1: 4 children
Son 2: 4 children
Son 3: 4 children
Son 4: 4 children
So you can find the total number of grandchildren by adding up the amount of children each of the sons have: 4 + 4 + 4 + 4 = 16
Rosemarie has 16 grandchildren.
b. If the are $8 total, and it is split equally between Rosemarie's sons, it means each son would get $2 (because $8 / 4 sons = 2).
And then each son would split it between his 4 kids. So $2 / 4 kids = $0.50
Each grandchild would receive $0.50 or 50 cents.

Answer:
See below.
Step-by-step explanation:
First question:
Think of the x-axis as a mirror. Quadrilateral is above the x-axis. Quadrilateral is below the x-axis. Quadrilateral ABCD was reflected across the x-axis. Quadrilateral A'B'C'D' is a mirror image of quadrilateral ABCD.
Quadrilateral ABCD undergoes a reflection across the x-axis to form quadrilateral A'B'C'D'.
Second question:
Quadrilaterals ABCD and A"B"C"D" are both turned the same way. Quadrilateral A"B"C"D" is just moved left and down from quadrilateral ABCD. That transformation is called a translation.
Quadrilateral ABCD undergoes a translation 7 units left and 1 unit down to form quadrilateral A"B"C"D".

Tim explained a function in words and Paul wrote an equation.
Tim
The amount of money in a savings account increases at a rate of $225 per month. After eight months, the bank account has $4,580 in it.
Paul
y−1,400=56(x+26)
Whose function has the smaller y-intercept?
Tim’s with a y-intercept of $2,700
Paul’s with a y-intercept of $2,856
Paul’s with a y-intercept of $2,800
Tim’s with a y-intercept of $2,780
Answer:
Tim's with a y-intercept of $2,780
Step-by-step explanation:
To find Paul's y-intercept, solve the equation y-1400=56(x+26) for y. Then use the standard format for a linear equation y=mx+b to determine the y-intercept which would be b.
Step 1. Get y by itself by adding 1,400 to both sides.
y-1400 + 1400 = y
56(x+26) + 1400 = 56(x+26) + 1400
New equation y = 56(x+26) + 1400
Step 2. Distribute 56(x+26)
56(x+26) = 56 * x + 56 * 26 = 56x + 1456
New equation y = 56x + 1456 + 1400
Step 3. Simplify.
y = 56x + 2856
Paul's y-intercept would be 2856 because when y=0 x=2856
To Find Tim's y-intercept, subtract 225 * 8 from 4580.
225 * 8 = 1800
4580 - 1800 = 2780
