Answer:
x = -2
Step-by-step explanation:
Subtract 5 from both sides (8x + 5 -5 = 6x + 1 -5);Subtract 6x from both sides (8x - 6x = 6x - 6x - 4);Divide both sides by 2 (2x / 2 = -4 / 2);Answer: x = -2Natasha was thinking of a number. Natasha adds 2, then divides by 8 to get an answer of -4. What was the original number?
Answer:
-34
Step-by-step explanation:
reverse the operation (-4 x 8) - 2
What value of x makes the equation `33x=11`true?
Answer:
3
Explanation: 3 times 11 is 33
The value of x that makes the equation true is 3.
What is an equation?An equation is a statement that equates to two expressions.
The given equation is:
[tex]33=11x[/tex]
[tex]11x=33[/tex]
Divide both sides by 11
[tex]\frac{11x}{11} =\frac{33}{11}[/tex]
[tex]x=3[/tex]
So, the required value of x=3.
Hence, The value of x that makes the equation true is 3.

Find the value of 3a+ 3b when: a = 6 and b = 4 a = 4 and b = 6 Your two answers should be the same. Look at the expression and the a and b values and explain why the answers are the same.
Answer:
The answer is 30.
Step-by-step explanation:
The given expression is :
3a+3b
Put a = 6 and b = 4 in the above expression.
3a+3b = 3(6) + 3(4)
= 18+12
= 30
Now put a = 4 and b = 6 in the above expression.
3a+3b = 3(4) + 3(6)
= 12+18
= 30
Hence, the answer in both case is same i.e. 30.

The parallelogram below will be cut into two congruent triangles. What is the area of one of the triangles?
Answer:
Area of each triangle = 35 cm²
Step-by-step explanation:
Given:
Base of parallelogram = 14 cm
Height of parallelogram = 5 cm
Two equal congruent triangles
Find:
Area of each triangle
Computation:
We know that equal congruent triangles have equal area
So,
Area of each triangle = Area of parallelogram / 2
Area of each triangle = Area of parallelogram / 2
Area of each triangle = [B x H] / 2
Area of each triangle = [14 x 5] / 2
Area of each triangle = [70] / 2
Area of each triangle = 35 cm²

Good morning, can someone help me solve this problem? I already did some of it but I need help, thank you
Answer: (-4, -1)
This means x = -4 and y = -1 pair up together.
======================================================
You're on the right track. You'll replace the 'x' with 3y-1, but you made a typo. I think you meant to write the subtraction symbol instead of the equal sign.
Here's what your steps could look like
-2x + 5y = 3
-2(3y-1) + 5y = 3
-6y + 2 + 5y = 3
-y + 2 = 3
-y = 3-2
-y = 1
y = -1
x = 3y-1
x = 3(-1) - 1
x = -3-1
x = -4
Therefore, (x, y) = (-4, -1) is the solution
-------------------
As the steps above show, I replaced each copy of x in the second equation with (3y-1). This is due to x = 3y-1. From there, we isolate y. Once you determine that y = -1, it's plugged into the first equation to find x.
If you were to graph x = 3y-1 and -2x+5y = 3 on the same xy coordinate grid, then the two lines would intersect at (-4, -1)
Also, note how plugging x = -4 and y = -1 into the second equation leads to...
-2x+5y = 3
-2(-4)+5(-1) = 3
8 - 5 = 3
3 = 3
We get the same value on both sides, so that verifies the second equation. I'll let you verify the first equation.

If the graph of the quadratic parent function q(x) = x2 is translated 3 units to the right and 2 units down, which of the following equations describes the translated graph?
Answer:
s(x) = (x - 3)^2 - 2
Step-by-step explanation:
q(x) = x^2 becomes r(x) = (x - 3)^2 after a 3-units-to-the-right translation.
This, in turn, becomes s(x) = (x - 3)^2 - 2, after a 2-units-down translation.

Simon lost his library card and has an overdue library book. When the book was 5 days late, he owed $2.25 to replace his library card and pay the fine for the overdue book. When the book was 21 days late, he owed $6.25 to replace his library card and pay the fine for the overdue book. Suppose the total amount Simon owes when the book is n days late can be determined by an arithmetic sequence. Determine a formula for an, the nth term of this sequence. Use the formula to determine the amount of money, in dollars, Simon needs to pay when the book is 60 days late.
Answer:
[tex](a)\ y = 0.25n +1[/tex]
[tex](b)\ \$16[/tex]
Step-by-step explanation:
Given
[tex]n \to days[/tex]
[tex]y \to amount[/tex]
[tex](n_1,y_1) = (5,2.25)[/tex]
[tex](n_2,y_2) = (21,6.25)[/tex]
Solving (a): Formula that represents the scenario.
Calculate slope (m)
[tex]m = \frac{y_2 - y_1}{n_2 -n_1}[/tex]
[tex]m = \frac{6.25-2.25}{21-5}[/tex]
[tex]m = \frac{4}{16}[/tex]
[tex]m = 0.25[/tex]
The equation is calculated using:
[tex]y = m(n - n_1) + y_1[/tex]
This gives:
[tex]y = 0.25(n - 5) + 2.25[/tex]
[tex]y = 0.25n - 1.25 + 2.25[/tex]
[tex]y = 0.25n +1[/tex]
Solving (b): Amount after 60 days late.
This means that:
[tex]n = 60[/tex]
So:
[tex]y = 0.25 * 60 + 1[/tex]
[tex]y = 15 + 1[/tex]
[tex]y = 16[/tex]
