Answer: x= [tex]\frac{85}{27}[/tex]=x
Step-by-step explanation:
1. Add 44 to both sides.
81+4=27x
2. Simplify 81+4 to 85.
85=27x
3. Divide both sides by 27.
[tex]\frac{85}{27}[/tex]=x
4. Switch sides.
X= [tex]\frac{85}{27}[/tex]

Find the values of x for which the function is continuous.
f(x) =
−3x + 7 if x < 0
x^2 + 7 if x ≥ 0
a.x ≠ 0
b.x ≥ 0
c.x ≥ root square 7
d.all real numbers
e.x ≠ 7
It looks like the given function is
[tex]f(x) = \begin{cases}-3x + 7 & \text{if }x < 0 \\ x^2+7 & \text{if }x \ge0\end{cases}[/tex]
The two pieces of f(x) are continuous since they are polynomials, so we only need to worry about the point at which they meet, x = 0. f(x) is continuous there if
[tex]\displaystyle \lim_{x\to0^-} f(x) = \lim_{x\to0^+} f(x) = f(0) = 7[/tex]
To the left of x = 0, we have x < 0, so f(x) = -3x + 7 :
[tex]\displaystyle \lim_{x\to0^-} f(x) = \lim_{x\to0} (-3x + 7) = 7[/tex]
To the right of x = 0, we have x > 0 and f(x) = x² + 7 :
[tex]\displaystyle \lim_{x\to0^+} f(x) = \lim_{x\to0} (x^2 + 7) = 7[/tex]
So f(x) is continuous at x = 0, and hence continuous for all real numbers.

if a area of a rectangle is 45...
set up an equation that must be true:
w = x
L = x-4
Answer: x times (x-4)=45
Step-by-step explanation:
First since the area is 45 that’s what the equation has to be equal to.
To find the area you always have to do length times width. So the width (x) times the length (x-4) equals 45.

Work out m and c for the line: 5 x − 3 y + 4 = 0
Step-by-step explanation:
5x - 3y + 4 = 0
we rearrange it to look like this:
y = mx + c
3y = -4 - 5x
we can also write it like this so it rhymes with the formula
3y = -5x - 4
y = -5x - 4 / 3 (the division sign is dividing all the numbers and not only 4 ).
Soo..
y = -5x/3 -4/3
y = mx. + c
so
m = -5/3
c = -4/3.
Hope this helps.
Good luck ✅.

We can't determine the slope (m) and the y-intercept (c) yet, so we need

[tex]\dagger[/tex] First, subtract 5x and 4 on both sides:-
-3y=-5x-4[tex]\dagger[/tex] Next, divide by -3 on both sides:-
y=5/3x+4/3[tex]\bigstar[/tex] A negative divided by a negative is a positive.
[tex]\dagger\dagger[/tex] Now finding the slope is a piece of cake; it's just the number next to x:-
5/3 = slope (m)And the y-intercept is:-
4/3 = y-intercept (c)Good luck with your studies.[tex]\rule{300}{1}[/tex]

You can do this 2 different ways. Either way, you need to use the bottom side of 8 cm and the two congruent segments. Each of the two congruent segments of the bottom side measures 4 cm.
Method 1) Find the area of the large triangle and subtract from it the area of the small triangle.
area of triangle = bh/2
shaded area = 8 cm × 6 cm / 2 - 4 cm × 3 cm / 2
shaded area = 24 cm² - 6 cm²
shaded area = 18 cm²
Method 2) The shaded region is a trapezoid with parallel bases of lengths 3 cm and 6 cm and height 4 cm. Find the area of the trapezoid.
area of trapezoid = (B + b)h/2
shaded area = (6 cm + 3 cm)(4 cm)/2
shaded area = (9 cm)(4 cm)/2
shaded area = 18 cm²
d)
The area of the shaded region is the area of the white triangle subtracted from the area of the rectangle.
area of rectangle = length × width
area of triangle = bh/2
shaded area = (12 cm)(4 cm) - (9 cm)(4 cm)/2
shaded area = 48 cm² - 18 cm²
shaded area = 30 cm²

Donna earns $1,404 per week at her job. However, 19% of her income gets taken out in taxes, and 12% of her income gets taken out and put into her retirement account.
Answer:
Step-by-step explanation:
A reasonable estimate of the amount Donna is left with each week after the money is deducted: $980. 1404*.19=266.76 ; 1404*.12=168.48 ; 1404-266.76-168.48=968.76 or estimated as $980.
welve books cost $59.88 and
books cost $104.79. Is there is a constant of proportionality between these purchases?
plain.
There is a constant of proportionality between the two purchases and each book costs $4.99.
Step-by-step explanation:A correspondence relation between two variables is of direct proportionality when the quotient between the corresponding quantities is always the same. This quotient is called the constant of proportionality.
In other words, when dividing any quantity of one of the magnitudes by the one that corresponds to it in the other, the value it gives is always the same. This value is known as the constant of proportionality.
In this case, the constant of proportionality [tex]k[/tex] will relate the number of books bought [tex]N[/tex] and their cost [tex]C[/tex] in the following way:
[tex]C=k*N[/tex]
So k is the price per book.
For the 12 books:
[tex]k=\frac{59.88}{12}[/tex]
[tex]k=4.99[/tex]
And for the 21 books:
[tex]k=\frac{104.79}{21}[/tex]
[tex]k=4.99[/tex]
The constant [tex]k[/tex] for the two purchases is the same, thus there is a constant of proportionality between the two purchases and each book costs $4.99.
Daisy estimated a certain expression to have a value of 300. Which of these
expressions could be the one Daisy estimated?
Select the two that apply.
A. 10x2
B. 30x2
C. 100x
D. 300
E. (5x)?
Answer:
C and D
Step-by-step explanation:
C). With the X right by the 100 means that it could be anything there, so you would put a 3 at the end so then 100 x 3 = 300.
D). The value is already 300 so no need to do work there.
Using Multiplication, 100 × 3 is this expressions could be the one daisy estimated.
What is multiplication?Multiplication is an "operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers".
According to the question.
Daisy estimated a certain expression to have a value is 300 using Multiplication we have,
100 × x =300
x = 300/100
x = 3.
Hence, 100 × 3 is this expressions could be the one daisy estimated using Multiplication.

Answer:
∠S = 19°
Step-by-step explanation:
Since all angles in a triangle add up to 180°, we must first find how much is left.
180 - 142 = 38
And since we know that the two lines are congruent, we know that the two other angles will be the same. So we divide the remaining by 2
38 ÷ 2 = 19
So both other angles are 19° meaning that ∠S is 19°
Hope this was helpful!
Answer: m∠S = 19°
Step-by-step explanation:
We know the angles of a triangle add up to 180° (and if you don't, you do now)
-> We are given one angle, 142°
-> We are given the fact this is an isosceles triangle, or one with two congruent sides
[] This means the other two angles are congruent
-> Taking this information, we will set up an equation to solve for x
180° = 142° + 2x°
38° = 2x
19° = x
x = 19°
x = m∠S, so m∠S = 19°
m∠S = 19°

What is the volume of this aquarium?
Answer:
9000 in³
Step-by-step explanation:
Small cube:
Volume = length x width x height
= 10 x 10 x 10 = 1000 in³
Big cube:
width (front) = 20
length (side) = 10 + 10 = 20
height (back) = 10 + 10 = 20
V = 20 x 20 x 20 = 8000 in³
Total volume: 1000 + 8000 = 9000 in³

#19. find the perimeter and the area of the figure
Answer:
Perimeter = 56 m
Area = __ m^2
Step-by-step explanation:
Perimeter = ___ m
Area = __ m^2
To find Perimeter, you have to add up all the sides of the shape,
5 + 5 + 5 + 11 + 7 + 7 + 16
= 56 m
Perimeter = 56 m
To find area, you have to multiply length times width,
5 × 5 = 25
7 × 16 = 112
112 + 25 = 137
Area = 137 m^2
Therefore the perimeter of this shape is 56 m and the area of this shape is 137m^2.
