Answer:
Students make in-out tables to assist them in noticing patterns and generalizing the mathematical relationships. Expect students to discover that area increases proportionally to the square of how much the side length increases.)
Tell whether the ordered pair is a solution of the given system:
(0,0) ; {y<-x+3
{y
Answer:
yes the ordered pair is a solution
Step-by-step explanation:
(x, y) = (0,0)
y < -x + 3
0 < - (0) + 3
0 < 3
true, ordered pair is a solution

Can someone help me with this?
Answer: A
Step-by-step explanation:
True or False: If there are multiple operations inside a parentheses, you do not need to complete these in the order of PEMDAS.
Answer:
False
Step-by-step explanation:
I would say false. The operations inside should always go by PEMDAS unless instructed otherwise
Answer:
FALSE
Step-by-step explanation:
Within a set of parentheses, the order of operations should be followed. This is because you will get the wrong answer if you don't.

write an equation of the line in a slope intercept form has a slope of -1/2 and passes through the point (2, 3)
Answer:
y = -¹/₂ x + 4Step-by-step explanation:
The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:
m = -¹/₂
(2, 3) ⇒ x₀ = 2, y₀ = 3
The point-slope form of the equation:
y - 3 = -¹/₂ (x - 2)
So:
y - 3 = -¹/₂ x + 1 {add 3 to both sides}
y = -¹/₂ x + 4 ← the slope-intercept form of the equation

you do 6x10 witch is 60 then you do 19 x 23 witch is 437 then divide that by 60 and that is 7 and you have 17 leftover
Lix wants to by a shirt for $25. What is the total cost with a 4.1% sales tax? Round to NEAREST CENT.
Answer:
about $26.00
Step-by-step explanation:
$25/100 = 0.25 for 1%
1% times 4.1 = 1.025 in sales tax
plus 25 equals 26.025
round to the nearest cent = $26.00

y= -5/3x + 3
y= 1/3x - 3
Answer:
y =-2/3x
x = 1
Step-by-step explanation:
adding both equations and then we find the value of y which is given below
y = -2/3x
and then putting the value of y in any above equation then we find the value of X which is given below
X = 1

A triangle has a perimeter represented by the expression 9x + 7
A square has a side length represented by 4x – 3.
Which expression represents the total perimeter of the two figures?
A) 20x
B) 4x2 + 9x – 5
C) 13x + 4
D) 25x – 5
Answer:
D. 25x-5
Step-by-step explanation:
you need to add all the sides of the square to get 16x-12 and then add 9x+7 to get D.
Pattern A start at 20 and has the rule subtract 2. Pattern b starts at 20 and has the rule subtract 1. Which shows the first several terms of patterns A and b
Answer:
c.
Pattern A: 20, 18, 16, 14, 12, 10
Pattern B: 20, 19, 18, 17, 16, 15
Step-by-step explanation:
Pattern A starts at 20 and the rule is to subtract 2. The terms will therefore be:
= 20, 18, 16, 14, 12, 10
The numbers above were gotten by subtracting 2 from each term for the next term.
Pattern B starts at 20 and the rule is to subtract 1. The terms will be:
= 20, 19, 18, 17, 16, 15
Correct option is therefore option C.

Step-by-step explanation:
3+(7-5)to the power of 2 x 6
Answer:
27
Step-by-step explanation:
PEMDAS
That is the order that you should solve complex equations
You first do equations in Parentheses
Then exponents
Then Multiplication or Division (whichever comes first in the equation)
Then Addition or Subtraction (again, whichever comes first in the equation)
So we first do the equation in parentheses, 7 - 5
7 - 5 = 2
Then we do the exponent (to the power of 2)
2 to the power of 2 is 4 (fun fact. 2 + 2 is the only equation that is the same in addition form and multiplication form)
Next, we multiply 4 by 6
4 x 6 = 24
And finally addition
3 + 24 = 27

Write the equation of a line that passes through the point (-1,5) and has a slope of -7. Your answer should be given in the form y = mx + b
Answer:
The equation of a line that passes through the point (-1,5) and has a slope of -7 will be:
y = -7x-2Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven
The point (-1, 5)Slope m = -7substituting m = -7 and the point (-1, 5) in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
5 = -7(-1) + b
5 = 7+b
b = 5-7
b = -2
Thus, the y-intercept is: b = -2
now substituting b = -2 and m = -7 in the slope-intercept form of the line equation
y = mx+b
y = -7x+(-2)
y = -7x-2
Therefore, the equation of a line that passes through the point (-1,5) and has a slope of -7 will be:
y = -7x-23 which number line best represents 2÷1/4
