Move all terms that don't contain b to the right side and solve. Hope this helps :)
Find the equation of the linear function represented by the table below in slope-intercept form.
x y
1 0
2 -3
3 -6
4 -9
Answer:
The equation is y = - 3x + 3
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-interceptThe rule of the slope is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]→ The table has 4 point: (1, 0), (2, -3), (3, -6), (4, -9)
→ We will choose two of them to find the slope
∵ The points (1, 0) and (2, -3) lie on the line
∴ [tex]x_{1}[/tex] = 1 and [tex]x_{2}[/tex] = 2
∴ [tex]y_{1}[/tex] = 0 and [tex]y_{2}[/tex] = -3
→ Substitute these values in the rule of the slope above
∴ [tex]m=\frac{-3-0}{2-1}=\frac{-3}{1}=-3[/tex]
∴ m = -3
→ Substitute the value of the slope in the form of the equation
∴ y = - 3x + b
→ To find b substitute x and y by the coordinates of a point on the line
∵ x = 1 and y = 0
∴ 0 = - 3(1) + b
∴ 0 = - 3 + b
→ Add 3 to both sides
∴ 0 + 3 = -3 + 3 + b
∴ 3 = b
∴ b = 3
→ Substitute the value of b in the form of the equation above
∴ y = -3x + 3
The equation is y = - 3x + 3
Answer:
y=-3x+1
because the slope is going up not down.

Write the coordinates of the vertices after a reflection across the x-axis.
Answer:
S(-6,6), T(2,6), U(2,0), V(-6,0)
Step-by-step explanation:
The coordinates of the vertices after a reflection across the x-axis. are S(-6,6), T(2,6), U(2,0), V(-6,0).
What is reflection?When a figure is built around a single point known as the point of reflection or the figure's center, a reflection point results. There is an exact opposite point on the other side of each point in the figure. The shape and size of the figure remain unchanged beneath the point of reflection.
Given points are S(-6,-6), T(2,-6), U(2,0), V(-6,0). The reflection of the points will be calculated as below:-
S(-6,-6) ⇒ S(-6,6)
T(2,-6) ⇒ T(2,6)
U(2,0) ⇒ U(2,0)
V(-6,0) ⇒ V(-6,0).
Therefore, the coordinates of the vertices after a reflection across the x-axis. are S(-6,6), T(2,6), U(2,0), V(-6,0).

whats the definition of nuts cells
Answer:
A nut is a fruit composed of an inedible hard shell and a seed, which is generally edible. In general usage and in a culinary sense, a wide variety of dried seeds are called nuts, but in a botanical context "nut" implies that the shell does not open to release the seed (indehiscent). The translation of "nut" in certain languages frequently requires paraphrases, as the word is ambiguous.

Solve the system by substitution.
2x +y+z= 12
5x + 5y + 5z = 20
х- 4y +z= -21
Answer:
(x, y, z) = (8, 5, -9)
Step-by-step explanation:
Using the first equation, we can write an expression for z:
z = 12 -2x -y
We can substitute this into the other two equations. (Before we do that, we'll divide the second equation by 5.)
x + y + (12 -2x -y) = 4 ⇒ -x +12 = 4
x -4y +(12 -2x -y) = -21 ⇒ -x -5y +12 = -21
__
The first of these gives us a value for x:
8 = x . . . . add x-4 to both sides
Using this in the second equation of these, we have ...
-8 -5y +12 = -21
-5y = -25
y = 5
Then the value of z is ...
z = 12 -2(8) -5
z = -9
The solution to the system is (x, y, z) = (8, 5, -9).

One way for a child to be identified as gifted in California is to have an IQ of 130 or above. A few years ago, a Los Angeles high school had a total enrollment of 2,830 students, of whom 410 were identified as gifted.
What is the proportion of students who were identified as gifted in this high school?
Answer:
41/283
Step-by-step explanation:
if you are referring to the proportion of gifted students to total students:
if 410 are gifted out of 2830 total, then 410/2830 of kids at the school are gifted
410/2830 = 41/283
