At 7pm, the temperature outside was -5 degree celsius. What does |-5| represent in this situation?
The number of degrees between 0 and -5 C
Step-by-step explanation:
Hi! It is not 1-5 is is the absolute value of -5. This would be 5 which is the number of degrees between 0 and -5.
Step-by-step explanation:
|-5| who’s absolute value is 5 is representing temp form 0 to -5
What is Temperature ?Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius
What is modulus?The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign. For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5.
According to question
At 7pm, the temperature outside was -5
And |-5| = 5 (which is absolute value)
And represent count of temp from 0 to -5 .
Hence, |-5| who’s absolute value is 5 is representing temp form 0 to -5

Multiply each equation by a constant that would help to eliminate the y terms. 2x-5y=-21 3x-3y=-18 What are the resulting equations?
Answer:
6x - 15y = -63
15x -15y = -90
Step-by-step explanation:
We need to multiply the two equations by a constant that will eliminate the y terms.
The two equations are:
2x - 5y = -21
3x - 3y = -18
Let us multiply the first by 3 and the second by 6. The resulting equations will be:
6x - 15y = -63
15x -15y = -90
Note: To solve the system of equations we can simply subtract the first from the second.

Why would someone choose to use a graphing calculator to solve a system of linear equations instead of graphing by hand? Explain your reasoning.Why would someone choose to use a graphing calculator to solve a system of linear equations instead of graphing by hand? Explain your reasoning.
We would prefer to use a graphing calculator because it will give a more exact solution, because it is easier to read, and because it is faster to do.
How to find a solution of a system of linear equations?
There are multiple ways, one of them is by graphing the lines and seeing where the lines intersect.
Now, there are two ways of doing this, graphing by hand and using a graphing calculator.
There are cases where graphing by hand is enough, but is more time-consuming than using a graphing calculator. But there are cases where the intersection happens at a point with irrational values, these cases is really hard to find the solution in a graph by hand (as it can have mistakes and you can't zoom in). While if you used a graphing calculator, you could zoom is as much as you want, so you would get a really good estimation for the solution.

Y-intercept:
To find the y-intercept, where the line crosses the y-axis, you need to find the value of y when x is 0.
Slope:
To find the slope of the line, use the equation:
(y₂ - y₁)/(x₂ - x₁)
where (x₁, y₁) is one point on the line and (x₂, y₂) is a different point on the line.
Equation:
y = (y-intercept) + x(slope)

express 1.875 in the form p/q
Answer:
If the answer asks for improper fraction it is [tex]\frac{15}{8}[/tex]
If it asks for simplest form it is [tex]1\frac{7}{8}[/tex]
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
[tex]1.875=\frac{1.875}{1}[/tex]
Multiply to remove 3 decimal places. Here, you multiply top and bottom by [tex]10^3=1000[/tex]
[tex]\frac{1.875}{1} *\frac{1000}{1000} =\frac{1875}{1000}[/tex]
Find the Greatest Common Factor (GCF) of 1875 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 125
[tex]\frac{1875/125}{1000/125} =\frac{15}{8}[/tex]
Simplify the improper fraction
[tex]=1\frac{7}{8}[/tex]

Answer:
y = 42
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use an ordered pair from the table.
Using x = 2 when y = 12, then
12 = 2k ( divide both sides by 2 )
6 = k
y = 6x ← equation of variation
When x = 7, then
y = 6 × 7 = 42

A teacher purchased 1 foot long sub to share amongst a group of 4 students. But decided to eat half of it. After dividing the rest of the sub into equal parts how much of a sub will each student recive?
Answer:
1/8th
Step-by-step explanation:
Answer:
1/8 of the sub or 1.5 inches
Step-by-step explanation:
One foot=12 inches, but the teacher eats half, so we are left with only six inches. then, divide the six inches with the number of students, which is 4. if you divide 12 and 1.5, you'll see that there are a total of 8 pieces, so one student gets 1 out of the 8

What is the vertex of the quadratic function below?
y = 3x2 - 12x+17
Answer:
D (2, 5)
Step-by-step explanation:
To find the vertex of the quadratic function , we will follow the steps below
(x,y) = [-b/2a , f(-b/2a)]
x = -b /2a y = f(-b/2a)
The standard equation of a quadratic equation is y =ax² + bx + c
compare the above with the equation given, y = 3x² - 12x + 17
a = 3 b= -12 and c= 17
x = -b/2a
x = -(-12)/2(3)
x = 12/6
x = 2
y = f(-b/2a)
y = f (-b/2a) = f(x) = f (2)
y = f(x) =3x² - 12x + 17
To find f(2) simply mean to substitute x = 2 into the quadratic function above. That is;
f(2) = 3(2)² - 12(2) + 17
f(2) =12-24 + 17
f(2) =5
x = 2 and y = 5
(x,y) = (2, 5)

The external angle of a regular polygon is 200 . How many sides does it have ? What is the measure of each interior angle? What is the total measure of its angles.
Answer:
An 18 sided shape.
Since the sum of the exterior angles of a polygon is 360° and an angle of the regular polygon is 20°, then 360° / 20° is the number of sides. We find the answer = 18, an octadecagon

Use the distributive property to write the sum as a product.
(-1)·2+(-1)·ₓ
Answer:
-1(2+x)
Step-by-step explanation:
in the initial equation the -1 was distributed, this answer creates a product (multiplication). -1(2+x)= -2-x
Answer:
(-1)·2+(-1)·ₓ = -1 (2+x)
Step-by-step explanation:
distributive property: ab +ac = a(b+c)
in this case a=-1, b =2, c =x so
(-1)·2+(-1)·ₓ = -1 (2+x)

Which line has a slope 3/4
Line C shown in the graph has a required slope of 3/4.
Given that,
A figure is shown we have to determine a line that has a slope of 3/4.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanФ where x in degrees.
m =(y₂ - y₁) / (x₂ - x₁) = tanФ
here,
The slope of the line A = ∞
The slope of the line D = 0
The slope of the line B = 4/ 3
The slope of the line C = 3/4
Thus, Line C shown in the graph has a required slope of 3/4.

Multiply. Your answer should be a monomial in standard form. {(-t^7)(-t^5)}
Answer:
t^12
Step-by-step explanation:
Because both multiplicands are negative, their product will be positive. Both multiplicands are to the same base: t.
Therefore, the product is t^(7 + 5), or t^12.
