Write the expression 44(4–7)(4) using a single exponent.
A) 4^–28
B) 4^–4
C) 4^–3
D) 4^–2
Answer:
D) 4^-2
Step-by-step explanation:
Given: 4^4*4^-7*4
If the base is the same, we can add the powers.
a^m * a^n = a^(m + n)
4^4*4^-7*4 = 4^(4 - 7 + 1)
= 4^(5 - 7)
= 4^-2
Answer: D) 4^-2

Work out the equation of the line which has a gradient of 2 and passes through the point (1,4)
Answer:
The equation would be y = 2x + 2
Step-by-step explanation:
We know that the equation of a line can be represented as:
(y - y1) = m ( x - x1)
where (x1, y1) is a point that belongs to the line and m is the gradient.
For this particular problem we would have (x1,y1) = (1,4) and m = 2.
If we substitute this data in the formula we get:
(y - y1) = m (x - x1)
y - 4 = 2(x - 1)
y - 4 = 2x - 2
y = 2x - 2 + 4
y = 2x + 2
Therefore, the equation would be y = 2x + 2
The equation of the line which has a gradient of 2 and passes through the point (1,4) is:
y = 2x + 2
What is gradientGradient also known as slope is the defined as
Gradient (m) = change in y coordinate / change in x coordinate
The equation of a line passing through a given point is given by the following equation:
y – y₁ = m(x – x₁)
How to determine the equation of the line passing through point (1,4)x coordinate (x₁) = 1y coordinate (y₁) = 4Gradient (m) = 2Equation =?y – y₁ = m(x – x₁)
y – 4 = 2(x – 1)
Clear bracket
y – 4 = 2x – 2
Make y the subject by adding 4 to both side
y – 4 + 4 = 2x – 2 + 4
y = 2x + 2

you are baking muffins for your class. there are 17 total students in your class and you have baked 5 muffins. write and solve an equation to find the additional number x of muffins you need to bake in order to have 2 muffins for each student. write your equation so that the units on each side of the equation are muffins per student
Answer:
Additional muffins required, x = 29
The equation so that the units on each side of the equation are muffins per student
[tex]\frac{5+x}{17}=2[/tex]
Step-by-step explanation:
Let the additional number x of muffins you need to bake in order to have 2 muffins for each student.
We have total number of students = 17
Number of muffins already baked = 5
So total number of muffins made = Number of muffins already baked + Additional muffins to be made
Total number of muffins made = 5 + x
We know that each student need to get 2 muffins
Total muffins needed = 17 x 2
Equating both
5 + x = 17 x 2
x = 34 - 5 = 29
Additional muffins required, x = 29
[tex]\frac{5+x}{17}=2[/tex]
This is the equation so that the units on each side of the equation are muffins per student

Destiny combines 6.42 liters of red paint with 6.87 liters of blue paint to make purple paint. she pours the paint equally into 3 containers, and has 2.64 liters of paint left over. how many liters of paint are in each container?
Quantity of paint in each container will be 3.55 liters
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Quantity of red paint = 6.42 liters
Quantity of blue paint = 6.87 liters
And, she pours the paint equally into 3 containers, and has 2.64 liters of paint left over.
Now,
Total quantity of paint = 6.42 + 6.87
= 13.29 liters
Thus, The quantity in each container = 13.29 - 2.64 / 3
= 10.65 / 3
= 3.55 liters.
Therefore, Quantity of paint in each container will be 3.55 liters

If x+z=15x+z=15 and w+y=10w+y=10, what is the value of (3w+3y)(2x+2z)(3w+3y)(2x+2z) ?
Answer:
The value of [tex]\((3w+3y)(2x+2z)\)[/tex] squared is [tex]\(810,000\).[/tex]
Explanation:
To find the value of [tex]\((3w+3y)(2x+2z)\)[/tex], we can first simplify each factor:
[tex]\((3w+3y) = 3(w+y)\)[/tex]
[tex]\((2x+2z) = 2(x+z)\)[/tex]
Given that [tex]\(w+y = 10\) and \(x+z = 15\)[/tex] , we can substitute these values into the expressions:
[tex]\((3w+3y) = 3(10) = 30\)[/tex]
[tex]\((2x+2z) = 2(15) = 30\)[/tex]
Now, we multiply these two simplified expressions together:
[tex]\((3w+3y)(2x+2z) = 30 \times 30 = 900\)[/tex]
So, the value of [tex]\((3w+3y)(2x+2z)\) is \(900\).[/tex]
To find the value of [tex]\((3w+3y)(2x+2z)\)[/tex] squared:
[tex]\((3w+3y)(2x+2z)^2 = (900)^2 = 810,000\)[/tex]
Therefore, the value of [tex]\((3w+3y)(2x+2z)\)[/tex] squared is [tex]\(810,000\).[/tex]

Zach is 23 years old. Zach's age is 3 years older than twice Maya's age. Let m represent Maya's age.
Which equation can be used to solve for Maya's age?
23 = 2m + 3
23 = 3m + 2
23 = m + 3
23 = 2m
Answer:
The correct option is A) [tex]23=2m+3[/tex].
Step-by-step explanation:
Consider the provided information.
Zach is 23 years old. Zach's age is 3 years older than twice Maya's age.
Let m represent Maya's age.
Twice of Maya's age can be written as:
[tex]2m[/tex]
3 years older than twice Maya's age can be written as:
[tex]2m+3[/tex]
It is given that Zach is 23 years old and Zach's age is 3 years older than twice Maya's age.
Thus, the above expression equal to 23.
[tex]23=2m+3[/tex]
Hence, the correct option is A) [tex]23=2m+3[/tex].

S is between T and V. R is between S and T. T is between R and Q. QV=18, QT=6, and TR=RS=SV. Find RS , QS , TS , and TV.
A line can have as many points as possible, and multiple lines can have similar points. The values of RS, QS, TS and TV are:
[tex]RS = 4\\QS =14\\TV = 12\\TS = 8[/tex]
S is a point between lines T and V means:
[tex]TV = TS + SV[/tex]
R is a point between lines S and T means:
[tex]TS = RS + TR[/tex]
T is a point between lines R and Q means
[tex]RQ = TR + QT[/tex]
Given that:
[tex]QT = 6\\QV = 18[/tex]
This means that Q is a point between lines QT and QV. So:
[tex]TV = QV - QT[/tex]
[tex]TV = 18- 6[/tex]
[tex]TV = 12[/tex]
[tex]TR=RS=SV[/tex] means that:
[tex]TV = TR+RS+SV[/tex]
Because [tex]TR=RS=SV[/tex], the equation becomes:
[tex]TV = TR+TR+TR[/tex]
[tex]TV = 3TR[/tex]
Substitute 12 for TV
[tex]12 = 3TR[/tex]
Divide both sides by 3
[tex]4 = TR[/tex]
[tex]TR =4[/tex]
Hence:
[tex]TR=RS=SV=4[/tex]
[tex]TS = RS + TR[/tex] gives
[tex]TS = 4 + 4[/tex]
[tex]TS = 8[/tex]
Next, we calculate the measure of QS from lines QV and SV
Point S is common between QS and SV. This means:
[tex]QV = QS + SV[/tex]
Make QS the subject
[tex]QS =QV -SV[/tex]
[tex]QS =18-4[/tex]
[tex]QS =14[/tex]
Hence, the values of RS, QS, TS and TV are:
[tex]RS = 4\\QS =14\\TV = 12\\TS = 8[/tex]
