Answer:
D) 18
Step-by-step explanation:
2x² - 6x = 540
2x² - 6x - 540 = 0
(2x + 30)(x - 18) = 0
x - 18 = 0
x = 18
2x + 30 = 0
2x = -30
x = -15; this cannot be the answer as it is negative

HELPPP. Find the line that has the mistake?
Answer:
Line 4
It is right
A linear equation is shown.
y
+
2
=
24
Which is the best description of the slope of the graph of this equation?
The slope is negative.
The slope is negative.
The slope is positive.
The slope is positive.
The slope is zero.
The slope is zero.
The slope is undefined.
Answer:
The slope is negative
Step-by-step explanation:
The equation is y+2x=24
We need to put this in slope intercept form to find the slope:
Subtract 2x on both sides:
y=-2x+24
(y=mx+b)
(m is slope) (b is y-intercept)
Thus the slope is negative
Since it is -2x

Any one know the y intercept?
y=2x+-3
Answer: -3
Step-by-step explanation:
the number at the end of the equation is the y-intercept. it's called "slope-intercept" form because the 2x that is at the beginning represents the slope, and the -3 at the end represents the y-intercept.
hope this helps!
Answer:
x= 3/2
Solution:
y=2x-3
Substitute y=0
0=2x-3
Move the variable to the left
-2x=-3
Divide by both sides
x= 3/2
Suppose the linear regression line y= 4.009x- 77.531 predicts a pizza parlor's profits based on the number of pizzas sold. If x represents the number of pizzas sold, and yrepresents the pizza parlors profits in dollars, about how much can the pizza parlor expect in profits if it sells 325 pizzas?
Answer:
The estimated profit is 62.784
Step-by-step explanation:
y = 4.009x - 77.531
Plug in the number of pizzas sold for x:
y = 4.009(35) - 77.531 = 140.315 - 77.531 = 62.784
Answer:
$1225
Step-by-step explanation:
When you take y=4.009x-77.531
x=325
y=4.009(325)-77.531
Answer would be $1225

gjj h 7/4 to the third power Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.
Step 1:
Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.
Step 2:
Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.
Step 3:
Combine like terms: (18 + 24) squared = 30 squared.
Step 4:
Evaluate each side: 1764 not-equals 900.
Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?
The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.
The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

Addition and Subtraction of Radical Expression
-Salamat
Given:
The radical expression is
[tex]7\sqrt[3]{8x^2y}+2\sqrt[3]{27x^5y^4}[/tex]
To find:
The value of the expression after addition.
Solution:
We have,
[tex]7\sqrt[3]{8x^2y}+2\sqrt[3]{27x^5y^4}[/tex]
It can be rewritten as
[tex]=7\sqrt[3]{2^3x^2y}+2\sqrt[3]{3^3x^3x^2y^3y}[/tex]
[tex]=7(2)\sqrt[3]{x^2y}+2\sqrt[3]{(3xy)^3x^2y}[/tex]
[tex]=14\sqrt[3]{x^2y}+2(3xy)\sqrt[3]{x^2y}[/tex]
[tex]=14\sqrt[3]{x^2y}+6xy\sqrt[3]{x^2y}[/tex]
Taking out the common factors, we get
[tex]=2\sqrt[3]{x^2y}(7+3xy)[/tex]
The value of given expression after addition is [tex]=2\sqrt[3]{x^2y}(7+3xy)[/tex].

At Paulson Middle School, 75% of the sixth grade class is making a B or higher. If there are 21 students
making a B or higher, then how many students are in the class?
Answer:
28 students
Step-by-step explanation:
x = Number of students
21 students = 75 percent of x = 3/4 x
3/4 x = 21
x = 21 * (4/3) = 7*4 = 28

Two less than 3times a number is the same as the number plus 10.
Answer:
6
Step-by-step explanation:
3n - 2 = n + 10. add 2
3n = n + 12 subtract n from both sides
2n = 12. divide by 2
N = 6
The number is 6
Write: y - 6 = -12(x+4) in slope intercept form-
Answer:
y= -12x - 42
Step-by-step explanation:
slope intercept form is y=mx +b
y-6 = -12(x+4) simplify
y - 6 = -12x - 48 separate y by adding 6 to both sides of the equation
y = -12x - 42

100 x 81 / 27 = 300
Which of the following expressions are equivalent to log base 2 24
Answer:
Option A, Option B and option D
Step-by-step explanation:
㏒₂ 72 - ㏒₂ 3 = ㏒₂ (72 ÷ 3)
= ㏒₂ 24
2 ㏒₂ 2 + log₂ 6 = log₂ 2² + log₂ 6
= log₂ 4 + log₂ 6
= log₂ (4*6)
= log₂ 24
log₂ 6 + log₂ 4 = log₂ (6*4)
= log₂ 24
