Step-by-step explanation:
The slope and y-intercept of a line that goes though (0,4) and (-5,5)
Answer:
slope= -1/5 y intercept 3
Step-by-step explanation:
(0,4) and (-5,5) can be rewriten as 5-4/-5-0, which equals -1/5. Then, you plug the numbers into the equation y= mx+b to get -4=-1/5(5)+b. That gets 3.

Question 3
Write an equivalent expression to 13.4x - 5.9 - 7.1x + 13.5 with the fewest possible terms.
Answer:
A........................
Answer:
13.4x - 0.5
Step-by-step explanation:
13.4x - 5.9 - 7.1 + 13.5
This may seem complicated, but it is really pretty simple once you get the hang of it.
First, you would organize your terms.
13.4x - 5.9 - 7.1 + 13.5
Then you would add your like terms.
-5.9 - 7.1 + 13.5 = 0.5
So the answer to your problem would be 13.4x - 0.5

Graph the following system of equation
y= 3x + 11
y= -4x + 4
Answer:
Step-by-step explanation:
Answer:
These equations describe two lines that intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4.
Step-by-step explanation:
We can find the point where these two lines intersect by taking one of the equations, solving it for x, and substituting it into the other equation.
[tex]y = -4x + 4\\-4x = y - 4\\4x = 4 - y\\x = 1 - \frac{y}{4} \\\\y = 3x + 11\\y = 3(1 - \frac{y}{4}) + 11\\y = 3 - \frac{3y}{4} + 11\\y + \frac{3y}{4} = 3 + 11\\\frac{4y}{4} + \frac{3y}{4} = 14\\\frac{7y}{4} = 14\\y = \frac{4}{7} * 14\\y = 4 * \frac{14}{7}\\y = 4 * 2\\y = 8[/tex]
Now we can plug that into our first equation to find x
[tex]x = 1 - \frac{y}[4}\\x = 1 - \frac{8}[4}\\\\x = 1 - 2\\x = -1[/tex]
So these lines intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4

The focus of a parabola is (-10, -7), and its directrix is x = 16. Fill in the missing terms and signs in the parabola's equation in standard form.
Answer:
The equation of the parabola in standard form is x = y²/52 + 7·y/26 - [tex]2\frac{3}{52}[/tex]
Step-by-step explanation:
The standard form of a parabola is a·y² + b·y + c
The focus of the parabola = (-10, -7), the directrix is x = 16, we have;
The coordinate of the focus is given as_F(h + p, k)
Where;
p = 1/(4·a)
The equation of the directrix is x = h - p
Therefore, given that the coordinates of the focus = (-10, -7), we have;
k = -7
Given that the equation of the directrix is x = 16, we have;
h - p = 16...(1)
h + p = -10...(2)
Adding equation (1) and (2), gives;
2·h = 6
h = 6/2 = 3
h = 3
From equation (1), p = h - 16 = 3 - 16 = -13
The general equation of the parabola is (y - k)² = 4·p·(x - h), therefore, substituting the values gives;
(y - (-7))² = 4 × (-13) × (x - 3)
(y + 7)² = -52·(x - 3)
y² + 14·y + 49 = -52·x + 156
x = (y² + 14·y + 49 - 156)/(-52) = (y² + 14·y + 49 - 156)/(-52) = y²/52 + 7·y/26 -107/52
Answer:
(y+7)^2= -52(x-3)

b/c the rule for x-axis is (x,y) --> (x, -y)
One of the points is (1, 1) ==> (1, -1)
4.) The rule for y-axis is (x, y) --> (-x, y)
A(-5, 3) --> A'(5, 3)
B(2, 6) --> B'(-2, 6)
C(-1, -7) --> C'(1, -7)
PAGE 2
5.) The rule for x-axis is (x,y) --> (x, -y)
A(-5, 3) ---> A'(-5, -3)
B(2, 6) ---> B'(2, -6)
C(-1, -7) ---> C'(-1, 7)
6.) The rule for 90 degrees clockwise is (x, y) --> (y, -x)
B(3, 4) ---> B'(4, -3)
PAGE 3
1.) On the transitions right is positive and left is negative
So 2 units to the right = +2
And 9 units down = - 9
So (x, y) --> (x + 2, y - 9)
2.) A is wrong b/c that translation is (x, y) ---> (x + 3, y -3)
B is wrong b/c the translation is (x, y) ---> (x + 3, y + 3)
C is wrong b/c the translation is (x, y) ---> (x - 3, y + 3)
D is correct b/c the translation is (x, y) --->(x -3 , y -3)
A(6, 6) --> A'(3, 3) B(7, 4) --> B'(4, 1) C(4, 4) --> C'(1, 1)
PAGE 4
7.) The rule for 90 degrees rotation counterclockwise is (x, y) --> (-y, x)
The correct graph would show A(-3, 3) ----> (-3, -3)
The only graph that shows this is Graph C
8.) The rule for 180 degrees rotation is (x, y) ----> (-x, -y)
The correct graph would show A(-3, 3) ----> A'(3, -3)
Graph B is the only one that ALL the angles follow this rule
PAGE 5
9.) It is Dilation with the center at the origin and a scale factor of 2.
B/c --> A(3, 3) ---> A'(6, 6) B(2, 0) ---> B'(4, 0) C(5, 2) ---> C'(10, 4)
(3*2= 6, 3*2=6) (2*2= 4, 0*2= 0) (5*2= 10, 2*2= 4)
10.) It is Dilation with the center at the origin and a scale factor of 1/3
B/c ---> A(-3, 6) --> A'(-1, 2) B(12, 3) ----> B'(4, 1) C(-6, -6) ---> C'(-2, -2)
(-3*1/3= -1, 6*1/3= 2) (12*1/3= 4, 3*1/3= 1) (-6*1/3= -2, -6*1/3= -2)
