Write an equation in the form y=mx+b that represents the x-y table
Choose two coordinates. I will choose the ones you chose, (-2, -3) and (0, 1).
Find the slope first using the slope equation: [tex]\frac{y2-y1}{x2-x1}[/tex]
y2 is 1, y1 is -3, x2 is 0, and x1 is -2.
[tex]\frac{1-(-3)}{0-(-2)}[/tex]
[tex]\frac{1+3}{0+2}[/tex]
[tex]\frac{4}{2}[/tex]
m = [tex]2[/tex]
The slope is 2.
Now that we found out the slope, we can start to assemble our equation. The m in the equation y = mx + b stands for the slope.
Now the equation is: y = 2x + b.
We need to figure out the y-intercept next. The b in the equation stands for the y-intercept. Choose one coordinate. I will chose (0, 1). x = 0 and y = 1. Substitute 0 in for x and 1 into y.
y = 2x + b
1 = 2(0) + b
1 = 0 + b
1 = b
Now we know what b is. Plug in 1 for b in the equation.
y = 2x + 1

Given f(x)=4x+5 and g(x)= x^2+x; find (f∘g)(-5)
Please show all steps thank you
Answer:
[tex](f\circ g)(-5)=85[/tex]
Step-by-step explanation:
We are given:
[tex]\displaystyle f(x)=4x+5\text{ and } g(x)=x^2+x[/tex]
And we want to find:
[tex](f\circ g)(-5)[/tex]
This is equivalent to:
[tex]\displaystyle =f(g(-5))[/tex]
So, we will evaluate g(-5) first, which yields:
[tex]\displaystyle g(-5)=(-5)^2+(-5)=25-5=20[/tex]
So:
[tex]=f(g(-5))=f(20)[/tex]
Then:
[tex]\displaystyle f(20)=4(20)+5=80+5=85[/tex]
Therefore:
[tex](f\circ g)(-5)=85[/tex]

Qual o raio de uma superfície esférica com 40 cm2 de área, em cm, aproximada às centésimas? Responde à seguinte questão, escrevendo apenas o valor numérico em algarismos
Responder:
1,78 cm
Explicación paso a paso:
El área de superficie total de la superficie esférica se expresa como;
T = 4πr² donde
r es el radio
Dado
TSA = 40 cm²
Sustituir
40 = 4πr²
r² = 40 / 4π
r² = 10 / π
r² = 10 / 3,14
r² = 3,185
r = √3,185
r = 1,78
por lo tanto, el radio de la esfera a la centésima más cercana es 1,78 cm

why do systems of nonlinear equations sometimes have more than one solution
Answer:
System has equal number of unknowns and equations.
Manipulation easily yielded expressions for 4 of the 7 unknowns.
However it seems that the remaining 3 unknowns x,y,z are not fixed by the equations. Different combinations (x0,y0,z0) seem possible without violating the system equations.
Is this possible, or did I most probably make a mistake in counting degrees of freedom?

The velocity of a car increases from 4 m/s at 2 sec. To 32 m/s at 9 sec. What is the car’s average acceleration?
Answer:
[tex]a=4\ m/s^2[/tex]
Step-by-step explanation:
Given that,
The velocity of a car increases from 4 m/s at 2 sec to 32 m/s at 9 sec.
We need to find the car's average acceleration. It can be given by the change in velocity divided by the change in time. So,
[tex]a=\dfrac{v-u}{t_2-t_1}\\\\a=\dfrac{32-4}{9-2}\\\\a=4\ m/s^2[/tex]
So, the car's average acceleration is equal to [tex]4\ m/s^2[/tex].
