Answer:
x=8
Step-by-step explanation:
1.5x = 12
Divide each side by 1.5
1.5x/1.5 = 12/1.5
x =8
x = 8
Step-by-step explanation:

D.y = 3x + 2 and y = 3x - 2
E.y=3 and x = 4
F. y = x 8 and y = -x + 3
Answer:
Step-by-step explanation:
If slope of two lines are equal, then they are parallel lines.
If product of the slope of two lines is (-1), then they are perpendicular lines.
C) y = x + 2
Slope m1 = 1
y = -x + 3
Slope m2 = -1
m1 * m2 = 1 * (-1) = -1
These are perpendicular lines.
D) y = 3x + 2
Slope = m1 = 3
y = 3x - 2
Slope = m2 = 3
Slopes are equal. So, they are parallel lines.
E)y= 3
This line is parallel to x -axis.
x = 4
This line is parallel to y-axis.
So, both lines are perpendicular to each other.
F) y = x + 8
slope m1 = 1
y = -x + 3
Slope = m2 = -1
M1 * m2 = 1 * (-1) = -1
So, These are perpendicular lines

If the length of a sea turtle is
directly proportional to its age,
and a 2-year old sea turtle is 3
inches long, how many feet long
is a 80-year old sea turtle?
Answer:
10 feet
Step-by-step explanation:
Let the length and the age of the sea turtle be L inches and A years old respectively.
Since its length is directly proportional to its age,
L= kA, where k is an unknown constant.
Let's find the value of the constant k.
L= kA
When L= 3, A= 2,
3= k(2)
2k= 3
k= 3 ÷2
[tex]k = \frac{3}{2} [/tex]
Substitute the value of k back into the equation:
[tex]L = \frac{3}{2} A[/tex]
When A= 80,
[tex]L = \frac{3}{2} (80)[/tex]
L= 120
Length of sea turtle
= 120 inches
= (120 ÷12) feet
= 10 feet

If he has 3.5 cups of sugar, how much flour does he need to make the muffins?
The constant of proportionality for the amount of flour to sugar in this recipe is ___.
If Kareem uses 3.5 cups of sugar, he will need ___ cups of flour.
The constant of proportionality for the amount of flour to sugar in this recipe is 2.
If Kareem uses 3.5 cups of sugar, he will need 7 cups of flour.
Two variables are said to be proportional if an increase in one variable leads to an increase in another variable and vice versa.
Let y represent the cups of flour and x represent the cups of sugar. Hence:
3.5 cups of flour for every 1.75 cups of sugar:
y ∝ x
y = kx
k is the constant of proportionality
3.5 = 1.75k
k = 2
y= 2x
If Kareem uses 3.5 cups of sugar, he will need:
y = 2x = 2(3.5) = 7
The constant of proportionality for the amount of flour to sugar in this recipe is 2.
If Kareem uses 3.5 cups of sugar, he will need 7 cups of flour.

Answer:
x = 11
Step-by-step explanation:
if the perimeters are equal then:
the perimeter of the first triangle : 3x + 9 + 3x + 3x + 8 = 9x + 17
the perimeter of the second triangle : 3x + 3x + 4x + 6 = 10x + 6 and
9x + 17 = 10x + 6 export like terms to the same side of the equation
17 - 6 = 10x - 9x
11 = x
we can find the lengths by replacing x with 11 in given expressions.

Answer: i needed pointsss srry
Step-by-step explanation:
Choose an equation that would be used to solve
0 = -x^2 + 10x -8
(x+25)^2 = -8
(x-5)^2 = 17
(x-10)^2 = 25
The equation that would be used to solve the function is (x+5)^2 = 17
Given the quadratic equation -x^2 + 10x -8 = 0
This can also be written as:
-x^2 + 10x -8 = 0
x^2 - 10x + 8 = 0
x^ 2- 10x = -8
The coefficient of x is -10
Half of the coefficient of -10 = -10/2 = -5
Square the result = 5^2 = 25
Add 25 to both sides of the equation
x^2 - 10x + 25 = -8 + 25
x^2 - 10x + 25 = 17
(x+5)^2 = 17
Hence the equation that would be used to solve the function is (x+5)^2 = 17

James uses 1 1/2 cups of milk and 2 1/4 cups of flour for his favorite cookie recipe. This makes 60 cookies. How much milk and flour would he need to make 40 cookies?
Answer:
to get you answer you would have to add 1 1/2 and 2 1/4, then your equation would be 60 ÷ 3 3/4 , then whatever your total is, multiply that by 40 and that would be your answer
The amount of milk and flour (x) that he needs to make 40 cookies will be 5/2 cups.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
James uses 1 1/2 cups of milk and 2 1/4 cups of flour for his favorite cookie recipe. This makes 60 cookies.
The amount of milk and flour will be
⇒ 1 1/2 + 2 1/4
⇒ 3/2 + 9/4
⇒ 15/4
Then the amount of milk and flour (x) that he needs to make 40 cookies will be
x / (15/4) = 40 / 60
x = 5/2 cups
The amount of milk and flour (x) that he needs to make 40 cookies will be 5/2 cups.
