[tex]\sqrt{40} = 6.32\\\\\\or\\5\sqrt{15} \\\\[/tex]
this is because when 40 is broken down into two numbers (one divisible to get out of the square root, and one not) you get 25 + 15 under the square root. we know that the square root of 25 is 5, so we can put 5 outside the root and leave 15 inside.

What is the y-intercept of the line that has a slope of -1/2 and passes through the point (2, 3)?
y=-1/2x+
=========================================================
Explanation:
For now, let's call the y intercept b
We'll plug in x = 2 and y = 3 from the given point to find b
y = mx+b
y = (-1/2)x + b
3 = (-1/2)*2 + b
3 = -1 + b
3+1 = b
4 = b
b = 4
The y intercept is 4
The equation of the line is y = (-1/2)x + 4
In y = -2x + 2, which of the following statements must be true about the
equation? (Check all that apply)
A) The slope is -2.
B) The equation represents a quadratic function.
C) The y-intercept is (0,-2).
D) From left to right, the line is decreasing or moving in a negative direction.
Hi there!
»»————- ★ ————-««
I believe your answer is:
A) The slope is -2.
D) From left to right, the line is decreasing or moving in a negative direction.
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
The equation given is in 'Slope-Intercept Form', where the equation gives the slope and y-intercept of a linear line. This would eliminate option B, since it is not quadradic.⸻⸻⸻⸻
[tex]\boxed{\text{Slope-Intercept Form is:}}\\\\y = mx + b\\\\\rightarrow m - slope\\\\\rightarrow b - \text'y-intercept\text'[/tex]
⸻⸻⸻⸻
In the equation [tex]y= -2x+2[/tex], the slope is '-2' (-2 takes m's place) and the y-intercept is (0,2). (2 takes b's place.)This would mark option A as a correct answer and eliminate option C. Line with negative slopes would go down if you were looking at the graph from left to right. Since the sign of the slope is negative, this would make option D a correct answer as well.⸻⸻⸻⸻
Options A and D should be correct.

Is p(4p - 9) =12 or p(4p - 9) - 12 quadratic?
pls need help
From: Brainly.ph (philippines)
Answer:
p(4p - 9) =12 ⇒ 4p² - 9p = 12 ⇒ 4p² - 9p - 12 = 0
This is a quadratic equationp(4p - 9) - 12 ⇒ 4p² - 9p - 12
This is a quadratic expressionStep-by-step explanation:
p(4p-9)=124p²-9p=12Since, it's one term has power 2 ,so it is quadratic
p(4p-9)-124p²-9p-12Since, it's one term has power 2, so it is quadratic
Write the slope-intercept form of the equation of the
line through the given point with the given slope.
10. through: (5, -3), slope -4/5.
Answer:
y = -4/5x + 1Step-by-step explanation:
The slope-intercept form:
y = mx + b, where m- slope, b- y-interceptUse point (5, -3) and m = -4/5:
-3 = -4/5*5 + b-3 = -4 + bb = -3 + 4b = 1The line is:
y = -4/5x + 1Answer:
b = 1
Step-by-step explanation:
We know that
y = mx + b
-3 = -4/5 × 5 + b
-3 = -20/5 + b
-3 = -4 + b
-3 + 4 = b
1 = b

Find the measures of the indicated angles pictures included!!!
Answer:
25
Step-by-step explanation:
The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

If P=(2,-1), find the image of P under the following rotation. 90 counter about the origin. Enter the number that belongs in the green box.
Step-by-step explanation:
If the image move 90⁰ counterclockwise then it will become (-2, -1).
The value of the image of P under the rotation 90 degree counter about the origin is, (1, 2)
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
Point P is,
P = (2, - 1)
Now, We know that;
To rotate quadrilateral ABCD 90° counterclockwise about the origin we will use the rule (x, y) becomes (-y, x).
Hence, The value of the image of P under the rotation 90 degree counter about the origin is,
= (- (- 1), 2)
= (1, 2)
Thus, The value of the image of P under the rotation 90 degree counter about the origin is, (1, 2)

Help what is the slope of the line?
9514 1404 393
Answer:
8/5 = 1.6
Step-by-step explanation:
It looks like the line crosses grid points (-4, -4) and (1, 4). This means the slope is ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-4))/(1 -(-4)) = 8/5 = 1.6
The slope of the line seems to be about 8/5, or 1.6.

What is a function?
Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given
f(x) = [tex]x^{3}+18x^{2} +104x+192 \ for x\leq -3[/tex]
f(x) = [tex]\frac{3x-9}{x^{3} -2x^{2} -5x+6} \ for -3\leq x\leq -3[/tex]
f(x) = [tex]\sqrt{x^{2} -9} \ for \ x > 3[/tex]
We need f(3)
f(x) = [tex]\frac{3x-9}{x^{3} -2x^{2} -5x+6} \ for -3\leq x\leq -3[/tex]
f(3) = [tex]\frac{3(3)-9}{3^{3} -2(3)^{2} -5(3)+6}[/tex]
f(3) = 0
Hence, f(3) is 0 for the given function.
