Answer:
[tex]\boxed {\boxed {\sf y= -4x -3}}[/tex]
Step-by-step explanation:
We are asked to find the equation of a line given a point and the slope. We will use the point-slope formula.
[tex]y-y_1= m(x-x_1)[/tex]
In this formula, m is the slope and (x₁, y₁) is the point the line passes through. The slope of this line is -4 and the line passes through (-2,5).
m= -4 x₁= -2 y₁ = 5Substitute the values into the formula.
[tex]y-5 = -4 (x--2)[/tex]
[tex]y-5 = -4 (x+2)[/tex]
We are finding the equation of the line, so we should find the slope-intercept form or y=mx+b ( where m is the slope and b is the y-intercept).We must isolate the variable y on one side of the equation.
First, distribute the -4 on the right side of the equation. Multiply each term inside the parentheses by -4.
[tex]y-5=( -4 *x ) + (-4* 2 )[/tex]
[tex]y-5 =(-4x)+ (-8)\\y-5= -4x -8[/tex]
5 is being subtracted from y. The inverse operation of subtraction is addition, so we will add 5 to both sides of the equation.
[tex]y-5 =-4x -8 + 5[/tex]
[tex]y= -4x -3[/tex]
The equation of the line is y= -4x -3. The slope of the line is -4 and the y-intercept is -3.

Can someone pls explain what I’m supposed to do I don’t really understand
Answer:
There are only 3 differences perform
Step-by-step explanation:
I. If x is negative, y is negative then the answer is possitive
eg. x is -2, y is -3
-2 × -3 = 6
II. If x is negative, y is positive then the answer is negative
eg. x is -1, y is 2
-1 × 2 = -2
III. If x is possitive, y is possitive then the answer is positive
eg. x is 2, y is 5
2 × 5 = 10
Alt. No matter how long x, y, z, a, b there always apply only 3 rules above. Multiply or Devide are the same rule.

Which of the following accurately completes the missing statement and justification of the two-column proof?
m∠BEC + m∠CED = m∠BED; Definition of a Linear Pair
m∠ABC + m∠BEC = m∠BED; Angle Addition Postulate
m∠ABC + m∠BEC = m∠BED; Definition of a Linear Pair
m∠BEC + m∠CED = m∠BED; Angle Addition Postulate
Considering the angle theorems, the appropriate answer to the question is option D. m∠BEC + m∠CED = m∠BED; Angle Addition Postulate
In the diagram, lines BC and ED are parallel and both were intersected by a transversal AE. Thus it can be observed that:
m<ABC = BED = [tex]70^{o}[/tex] (corresponding angle theorem)
But,
m<BEC + m<CED = m<BED (angle addition postulate)
with m<CED = [tex]30^{o}[/tex], and m<BED = [tex]70^{o}[/tex]
So that,
m<BEC + [tex]30^{o}[/tex] = [tex]70^{o}[/tex]
m<BEC = [tex]70^{o}[/tex] - [tex]30^{o}[/tex]
= [tex]40^{o}[/tex]
m<BEC = [tex]40^{o}[/tex]
Since linear pair are two angles that add up to [tex]180^{o}[/tex]. Therefore the required answer is option D.
i.e D. m∠BEC + m∠CED = m∠BED; Angle Addition Postulate

What is CD? to number 11
Answer:
CD = 38
Step-by-step explanation:
BC + CD = BD
8x + 8 + 6x - 28 = 10x + 24
8x + 6x + 8 - 28 = 10x + 24 {Combine like terms}
14x - 20 = 10x + 24 { Add 20 to both sides}
14x = 10x + 24 + 20
14x = 10x + 44 {Subtract 10x form both sides}
14x - 10x = 44
4x = 44 {Divide both sides by 4}
x = 44/4
x = 11
CD = 6x - 28 = 6*11 - 28 = 66 - 28 = 38
A figure is transformed according to the rule (x,y) = (x-1, y + 4). What transformation has taken place?

B. Translation of each point 1 unit to the right and 4 units up.
C. Dilation by a scale factor of -1/4.
D. Reflection over the x-axis, then translated up 4 units.
The answer is A because x-1 means moving left 1 on the x axis. As well, y+4 means moving 4 up on the y axis.

What's the value of u+ v
The hypothetical solution for the values of u + v = 3/10
The values of u and v aren't given in the question. However, giving an hypothetical solution to the problem.
Since we have an addition operator to be used on the values of u and v
Taking the values of u and v to be a real number such as :
u = 1/10 and v = 1/5
u + v = 1/10 + 1/5
Taking the L. C. M of 10 and 5;
L. C. M = 10
HENCE,
u + v = 1/10 + 1/5 = (1 + 2) / 10 = 3/10
Hence, the value of u + v = 3/10

Please, show your work if you have a answer to this question.
Answer:
A: 113.04in^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2 where r is the radius
We know the diameter is 12 inches so the radius is 1/2 the diameter
r = 1/2 d =1/2(12) = 6inches
A = (3.14) (6)^2
A = 113.04 in ^2

The can contains 15.7 g of sugar per 100 mL. So if the can holds 330 mL of soft drink, then overall it contains
(15.7 g) / (100 mL) × (330 mL) = 51.81 g
of sugar, and this is
(51.81 g) / (90 g) ≈ 0.575667 ≈ 57.6%
so Tom's friend is correct.
