What is the value of x in the system of equations shown below?
5x + 4y = 1
y = 1 - x
Answer:
x=-3
Step-by-step explanation:
Answer:
x = -3
Step-by-step explanation:
Plug in
5x + 4(1 - x) = 1
(y gets replaced by 1 - x)
Multiply
5x + 4 - 4x = 1
(multiply 4 by whats in the parenthesis)
Combine Constants
5x - 4x = -3
(constant = numbers without a variable)
(separate constants from variables = numbers with letters)
Combine Variables
1x = -3
(then you got your answer and you can take the "1" off the x)
f (x) = x2 + 4
What is the value of x when f (x) = 42
A. -2
В. 0
C 12
D. 20
Answer:
f(x)=X^2+4
f(x)=42
42=X^2+4
X^2+4=42
X^2=42-4
X^2=38
X=sqrt(38)=6.16

Answer: A. A' (0, 6), B' (0, 4), C' (-3, 3)
Step-by-step explanation:
A (3, 0), B (3, -2), C (0, -3)
A translation by vector <-3, 6>
Add the x-coordinate of each points to -3 and add the y-coordinates to 6
A (3, 0) -> 3 + -3 = 0 0 + 6 = 6 A' (0, 6)
B (3, -2) -> 3 + -3 = 0 -2 + 6 = 4 B' (0, 4)
C (0, -3) -> 0 + -3 = -3 -3 + 6 = 3 C' (-3, 3)
A' (0, 6), B' (0, 4), C' (-3, 3)

Which transformation was performed on PQRS to form P'QʻR'S'? (1 point)
1) A dilation factor of 2
2) A dilation factor of 4
3) A dilation factor of 1/2
4) A dilation factor of 1/4
Given:
A transformation was performed on PQRS to form P'QʻR'S'.
To find:
The transformation.
Solution:
The given graph shows two similar polygons. It means, dilation was performed.
From the given graph it is clear that,
[tex]PS=2[/tex] units
[tex]P'S'=1[/tex] units
Now,
[tex]\text{Scale factor}=\dfrac{P'S'}{PS}[/tex]
[tex]\text{Scale factor}=\dfrac{1}{2}[/tex]
A dilation factor of [tex]\dfrac{1}{2}[/tex] was performed on PQRS to form P'QʻR'S'.
Therefore, the correct option is (3).

Write an equation in paint-slope form of the line that passes through the point (3, 5) and has a slope of m = - 1
9514 1404 393
Answer:
y -5 = -(x -3)
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
For m=-1 and (h, k) = (3, 5), the equation of the line is ...
y -5 = -(x -3)
Answer:
y-5=-1(x-3)
Step-by-step explanation:
Point slope form: y-y1=m(x-x1)
