Answer:
yes
Step-by-step explanation:
When forming a triangle, the sum of 2 of the sides must be greater than the third. In this case 12+9=21 which is greater than the third side (21>19)
Solve the literal equation y = 12x - 5cx for x
Answer: x=y/(12-5c)
Step-by-step explanation:
To solve for x, we need to use algebraic properties.
We notice that each term on teh right side contains an x. We can factor out an x.
y=12x-5cx [factor out x]
y=x(12-5c) [divide both sides by 12-5c]
x=y/(12-5c)
1. If 4 = ( p – 2 ) then the solution of p = ------
2.In the expression x/4 = 2/3 what is the value of the x
Answer:
x = 8/3
Alternative form
x = 2 2/3, x = 2.6
Step-by-step explanation:
First, simplify the equation using cross-multiplication
3x = 8
then divide both sides of the equation by 3 and there's your answer
x = 8/3

Step-by-step explanation:
find the x value for one triangle then times it by 2
Pythagorean Theorem: [tex]a^{2}+b^{2}=c^{2}[/tex]
[tex]c=\sqrt{13}[/tex]
[tex]a=2[/tex]
Square c and subtract a from it.

square root 9 to get have of the x value, then multiply it by 2
[tex]2\sqrt{9}=6[/tex]
[tex]x=6[/tex]
FIRST ANSWER GETS BRANLIEST!!
Answer:
(0,0)
Step-by-step explanation:
Let's think about how the graph of this would look.
We know that y will be [tex]x^2[/tex], meaning that if x was 0, y would be 0.
If x was 1, y would be 1
If x was 2, y would be 4.
Now let's think about negative numbers.
If x was -1, y would be 1 (since [tex]-1^2 = 1[/tex]
If x was -2, y would be 4 (since [tex]-2^2 = 4[/tex]).
This means that our graph would turn at the point where x and y are equal (excluding 1,1)
This is 0,0.
So 0,0 is the turning point of this graph.
Hope this helped!

Order the numbers from least to greatest. 1=least and 4=greatest LaTeX: \sqrt{\frac{9}{4}}9 4 LaTeX: \sqrt{5}5 LaTeX: 2.52.5 LaTeX: \frac{5}{3}5 3
Answer:
[tex] \sqrt{\frac{9}{4}} [/tex] < [tex] \frac{5}{3} [/tex] < [tex] \sqrt{5} [/tex] < 2.5
Step-by-step explanation:
Given the following numbers, [tex] \sqrt{\frac{9}{4}}, \sqrt{5}, 2.5, and, \frac{5}{3} [/tex], let's express each as whole or decimal numbers, to find out the least to the greatest.
[tex] \sqrt{\frac{9}{4}} = \frac{\sqrt{9}}{\sqrt{4}} [/tex]
[tex] \frac{3}{2} = 1.5 [/tex]
[tex] \sqrt{5} [/tex] ≈ 2.2
2.5 (already in decimal form)
[tex] \frac{5}{3} [/tex] ≈ 1.7
From the least to the greatest, we have:
[tex] \sqrt{\frac{9}{4}} [/tex] < [tex] \frac{5}{3} [/tex] < [tex] \sqrt{5} [/tex] < 2.5

Addition Property of equality
Combine like terms
Definition of midpoint.
Division property of equality
Segment addition postulate
Answer:
Step-by-step explanation:
Given the following lengths AB = 64, AM = 4x + 4 and BM= 6x-10, If M lies on the line AB then AM+MB = AB (addition property)
Substituting the given parameters into the addition property above;
AM+MB = AB
4x + 4 + 6x - 10 = 64
combine like terms
4x+6x = 64+10-4
10x = 74-4
10x = 70
Divide both sides by 10
x = 70/10
x = 7
Note that for M to be the midpoint of AB then AM must be equal to BM i.e AM = BM
To get AM ;
Since AM = 4x+4
substitute x = 7 into the function
AM = 4(7)+4
AM = 28+4
AM = 32
Similarly, BM = 6x-10
BM = 6(7)-10
BM = 42-10
BM = 32
Since AM = BM = 32,. then M is the midpoint of AB

Which of the following ratios are equivalent to 60%?
Check all that apply.
O A. 4:6
OB. 10:20
O C. 12:36
O D. 3:5
O E. 15:25
Answer:
D. 3:5 and E. 15:25
Step-by-step explanation:
If it is 60%, it means that the ratio is 6:10 (60/100).
Because both 6 and 10 are divisible by 2, we can then simplify the ratio to 3:5.
Therefore it is D. 3:5
We can then multiply both sides by 5 which will give us 15:25, so E is also correct.
The others of not correct because they are not equivalent to the ratio 3:5.

The endpoints of GH are G(3,3) and H(-7,7).
Find the coordinates of the midpoint M.
Step-by-step explanation:
Hey there!!
You can simply use midpoint formulae to find midpoint of the coordinates.
Here, Given that;
G(3,3) and H(-7,7).
Using midpoint formulae,
[tex]midpoint \: of \: gh = (\frac{x1 + x2}{2} ,\frac{y1 + y2}{2} [/tex])
[tex]midpoint \: of \: gh = (\frac{3 - 7}{2} ,\frac{3 + 7}{2} [/tex])
After simplifying it we get,
= (-2,5).
Therefore, midpoint of GH is M(-2,5).

15 = 2x – 10 step and solution
Answer:
12.5 =x
Step-by-step explanation:
15 = 2x – 10
Add 10 to each side
15+10 = 2x – 10+10
25 = 2x
Divide by 2
25/2 = 2x/2
12.5 =x
Answer:
25/2
Step-by-step explanation:
2x-10=15
+10 +10
2x=25
divide both sides by 2 to get 25/2
The teacher has 125 pencils they want to arrange in y amount of containers in the class. Write an expression to show how many pencils will be in each container.
Answer:
125/y
Step-by-step explanation:
Answer:
[tex]\frac{125}{y}[/tex]
Step-by-step explanation:
If you have 125 pencils and you have [tex]y[/tex] amount of containers, then you want to get an equal number of pencils in each container.
What operation do we know of that finds an equal distribution across a certain number of groups? Division! That can help us equally split a number into how many parts we need.
Division can be represented in two ways: with a division sign [tex]\div[/tex] or as a fraction [tex]\frac{x}{y}[/tex].
You'll find the that the division sign will be used a lot less during Algebra and you'll mainly stick to fractions.
If we are dividing 125 into [tex]y[/tex] groups, then our fraction is [tex]\frac{125}{y}[/tex].

Last week, Donnell practiced the piano 3 hours longer than Marcus. Together, Marcus and Donnell practiced the piano for 11 hours. For how many hours did each young man practice the piano?
Answer:
4 hours and 7 hours
Step-by-step explanation:
Marcus = x hours
Donnell = x + 3 hours
Total = 11 hours
x + x + 3 = 112x + 3 = 112x = 8x = 4So Marcus practiced 4 hours and Donnell practiced 7 hours
Answer:Marcus=4 Donnell=7
Step-by-step explanation:11-3=8
8÷2 =4
4+3=7 hours used by Donnell
Remaining 4 hours is used by Marcus

l= a+(n-1)d
SOLVE FOR N
Answer:
[tex]n = \frac{l-a}{d}+1[/tex]
Step-by-step explanation:
[tex]l= a+(n-1)d\\[/tex]
[tex]l -a =(n+1)d[/tex]
Divide both sides of the equation by d
[tex]\frac{l-a}{d} = \frac{(n-1)}{d}\\ \\\frac{l-a}{d} = n-1\\\\\frac{l-a}{d}+1 = n[/tex]
