True or False? A triangle can have side lengths of 3, 3 , and 6
Answer:
No
Step-by-step explanation:
We can check with the Pythagorean Theorem.
a^2 + b^2 = c^2
a and b are always the smaller sides, the legs
c is the longer side, the hypotenuse
3^2 + 3^2 > 6^2
9 + 9 > 36
18 < 36
18 is not greater than 36, therefore this triangle can not have the side lengths 3, 3, and 6.
Find the product of 6/7•5/7
Hey there!
The word “product” simply means the result of a multiplication equation
MULTIPLY the NUMERATORS (TOP numbers) from each other and also MULTIPLY the DENOMINATORS (BOTTOM number) from each other
6(5) / 7(7) = ?
6(5) = 30 ⬅️ NUMERATOR
7(7) = 49 ⬅️ DENOMINATOR
Possible ANSWER: 30/49

Twice the sum of x and 3 is decreased by 13
Given:
Twice the sum of x and 3 is decreased by 13.
To find:
The expression for the given statement.
Solution:
The sum of x and 3 is (x+3).
Twice the sum of x and 3 is two times of (x+3), i.e., 2(x+3)
Negative sign is used of decrease.
Decreased by 13 is represented by -13.
Using these representation, we get
Twice the sum of x and 3 is decreased by 13: [tex]2(x+3)-13[/tex]
Therefore, the required expression is [tex]2(x+3)-13[/tex].

=======================================================
Explanation:
Think of x as a placeholder for a number. For me, I tend to think of it as a box. It's handy that the letter x is part of box, to help make that connection better. We have some box and inside the box goes a number.
If we multiply 5 by whatever is in the box, we can write it like [tex]5*\square[/tex]
Then let's say we fill that box with the value 7. We would then have [tex]5*\boxed{7}[/tex]
If we put 3 in the box instead we'll have [tex]5*\boxed{3}[/tex] and so on
Unfortunately the box symbol isn't something we could easily write on a keyboard, so we go with x instead to make life simpler.
--------------------------
So far we've shown that "5 times a number" turns into 5*x or just 5x.
From here we subtract off 3 to get 5x-3 as the final answer. Whatever the result of 5x is, we subtract off 3.
The answer would not be 3-5x since this means "subtract 5x from 3". The order of subtraction matters. In general, A-B is not the same as B-A.
What is the approximate circumference of the circle shown below
Answer: A) 46.5 cm
Step-by-step explanation:
Circumference = 2 π r or Circumference = π d
In this case, they give us the diameter = 14.8 cm. Therefore the radius = 14.8/2 = 7.4 cm.
π ≈ 3.14.
We can use either equation above, but because the diameter was given, we will use c = πd for simplicity.
C = π d
= (3.14)(14.8)
= 46.47 cm, which rounds to 46.5 cm

What are congruent triangles?A closed polygon made of three line portions shaping three points is known as a Triangle.
If the sides of two triangles are the same length and the angles are the same size, they are said to be congruent. As a result, it is possible to superimpose two triangles side by side and angle by angle.
Given triangles
ΔUTS and ΔRTS
which shows
UT and RS are parallel
and TS is common side
so ∠UTS = ∠RST
by UT ║ RS (side)
∠UTS = ∠RST (angle)
TS = TS (common side)
ΔUTS ≅ ΔRTS

e. Check your answer:
Answer:
Step-by-step explanation:

__$55__ = __50__ x + __30_ y

55 =50x+30y
-1(45) =(30x+30y)-1 = -45=-30x-30y
55 =50x+30y
+ -45=-30x-30y
10=20x
(1/20)10=20x(1/20)
0.50=x
3(55) =(50x+30y )3 = 165=150x+90y
-5(45) =(30x+30y)-5 = -225=-150x-150y
165 =150x+90y

A mechanical pencil costs _$0.50__ and a ruler costs __$1.00__.
e. Check your answer:
$55=50x+30y $45=30x+30y
$55=50(0.5)+30(1) $45=30(0.5)+30(1)
$55=25+30 $45=15+30
$55=$55 $45=$45
A mechanical pencil costs $0.50 and a ruler costs $1.00.
What is meant by cost?In calculus, a cost function is a mathematical formula used to determine how much it will cost to produce a certain number of units. The total cost formula is used to calculate the total cost by combining the variable and fixed costs of providing goods. Total cost = (average fixed cost x average variable cost) x number of units produced. A unit price is defined as a price expressed as a quantity of one, such as $25 per ticket or $0.89 per can. If you have a non-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the unit price, divide the terms of the ratio.The current answer as follows:
a. Fill in the blanks to calculate Mrs. Ortiz's purchase price. Let x denote the price of a pencil and y the price of a ruler.
$55 = 50x + 30y
b.Fill in the blanks with the cost of Mr. Donahue's purchase. Let x represent the cost of a pencil and y represent the cost of a ruler.
$45 = 30x + 30y
c. Circle the best method for solving the system:
Elimination
d. Solve the system using the method you chose.
55 = 50x + 30y - 1(45) = (30x + 30y) - 1 = -45 = -30x - 30y
55 = 50x + 30y + -45 = -30x - 30y
10 = 20x
(1/20)10 = 20x (1/20)
0.50 = x
3(55) = (50x + 30y )3 = 165 = 150x + 90y
-5 (45) = (30x + 30y) - 5 = -225 = -150x - 150y
165 = 150x + 90y + -225 = -150x - 150y
-60 = -60y
(1/-60) -60 = -60y (1/-60)

Step-by-step explanation:
20x² = y - 24
y = 20x² + 24
For y to have the least possible value, x² have to be the least possible, which is 0.
Since -3 <= x <= 2 includes x = 0, this is allowed.
Hence least possible value of y
= 20(0)² + 24 = 24.
Answer:
24
Step-by-step explanation:
-3---> 20(-3)^2=y-24 ----> y=204
-2---> 20(-2)^2=y-24 ----> y=104
-1---> 20(-1)^2=y-24 ----> y=44
0---> 20(0)=y-24 ----> y=24
1---> 20(1)^2=y-24 ----> y=44
2---> 20(2)^2=y-24 ----> y=104

b)
see in the table, at x = {-3; 0; 2}, y = 0
=> x = {-3; 0; 2} is the solutions of the equation x³ + x² - 6x = 0
Step-by-step explanation:
a) 0 and 6 will be written in the given blank spaces.
b) The value of x for the given equation is 0, -3 and 2.
Substitution method?It is a method for finding the values of variable, by substituting the value of one variable to get the another.
How to solve a polynomial equation?To solve a polynomial equation, first write it in standard form. Once it is equal to zero, factor it and then set each variable factor equal to zero.
a). We have, an equation
[tex]y = x^{3}+x^{2} -6x[/tex]
so, at x = -3
[tex]y = -3^{3} +(-3)^{2} -6(-3)[/tex] = -27+9+18 = 0 (substitute x = -3 in the given equation)
at x = -1
y = [tex]-1^{3} +(-1)^{2} -6(-1) = -1+1+6 = 6[/tex]
Hence, 0 and 6 will we written the blank spaces of the given table.
b). We have an equation
[tex]x^{3} +x^{2}-6x = 0[/tex]
⇒ [tex]x(x^{2} +x-6)=0[/tex]
⇒ [tex]x (x^{2} +3x-2x-6)=0[/tex]
⇒ [tex]x(x(x+3)-2(x+3))=0[/tex]
⇒ [tex]x(x+3)(x-2)=0[/tex]
⇒ [tex]x = 0,-3 and 2[/tex]
Hence, 0, -3 and 2 are the solutions of the given equation.
