Answer:
y = -4x + 1
Step-by-step explanation:
Okay, one way we can find the equation is to plug the x and y values into y = mx + b
We m (slope) is -4 so
y = -4x + b
We want to find b so we plug in x and y (-2 and 9)
9 = -4 (-2) + b
9 = 8 + b
In this case, b is 1
Now we plug this to make our equation,
y = -4x + 1
Answer:
3x^2 +14x-5
Step-by-step explanation:
(3x-1)(x+5)
We need to FOIL
first 3x*x =3x^2
outer 3x*5 = 15x
inner -1*x = -x
last -1*5 =-5
Add it together
3x^2 +15x-x-5
Combine like terms
3x^2 +14x-5
Answer:
Domain: {-2, -1, 0, 1, 2}
Range: {-5, -1, 3, 7, 11}
Step-by-step explanation:
Given the function, f(x) = -4x + 3:
We could simply substitute the given x-values into the function to solve for its corresponding y-values:
x = -2:
f(-2) = -4(-2) + 3
f(-2) = 8 + 3
f(-2) = 11
x = -1:
f(-1) = -4(-1) + 3
f(-1) = 4 + 3
f(-1) = 7
x = 0:
f(0) = -4(0) + 3
f(0) = 0 + 3
f(0) = 3
x = 1:
f( 1 ) = -4( 1 ) + 3
f( 1 ) = -4 + 3
f( 1 ) = -1
x = 2:
f(2) = -4(2) + 3
f(2) = -8 + 3
f(2) = -5

<em>*Remember that A = angle and S = side.</em>
So remember that <u>similar figures have congruent angles and proportional sides.</u> Looking at triangles ABC and DEF, they both share 85° and 30° angles. <u>With this, the two triangles are similar by AA, or the first option.</u>
