Geometry problem plz help?
Step-by-step explanation:
let eqn be y = mx + b.
m = (9 - 1)/(2 - 4) = -4
sub (4, 1):
1 = -4(4) + b
b = 17
therefore, it's y = -4x + 17

Answer:
A = {put, the, cake, in, basket}
B = {is, the, cake, in, basket}
C = {no, the, cake, in, basket}
D = { }
Step-by-step explanation:
A = (A -B) ∪ (A∩B) ∪ (A∩C}
A = {put} ∪ {the, cake, in, basket} ∪ {the, cake, in, basket}
A = {put, the, cake, in, basket}
__
B = (B -A) ∪ (B -C) ∪ (B∩A) ∪ (B∩C)
B = {is} ∪ {is} ∪ {the, cake, in, basket} ∪ {the, cake, in, basket}
B = {is, the, cake, in, basket}
__
C = (C -B) ∪ (C∩A) ∪ (C∩B)
C = {no} ∪ {the, cake, in, basket} ∪ {the, cake, in, basket}
C = {no, the, cake, in, basket}

(-8,7), m=5
Y-7=5(x+8)
Answer:
The line of the equation is:
[tex]y-7=5\left(x+8\right)[/tex]
Step-by-step explanation:
Given
m=5point (-8, 7)As the point-slope form is given by
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope
substituting the values m=5 and the point (-8, 7)
[tex]y-7=5\left(x-\left(-8\right)\right)[/tex]
[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]
[tex]y-7=5\left(x+8\right)[/tex]
Therefore, the line of the equation is:
[tex]y-7=5\left(x+8\right)[/tex]

PLEASE HELP !! Timed test Which equation represents the relationship between x and y in the table?
Answer:
divided by 5
Step-by-step explanation:
Hope that helps!
Answer:
Answer Choice D- y=x/5
Step-by-step explanation:
All the numbers in the table fit in and correlate to the equation. You can substitute any of the x's into the equation and get y correctly this is why the equation y=x/5 is the solution.
If you can please make my answer the brainliest that would be much appreciated. Thanks!
Lila wrote an equation of the cost for printing brochures, where x represents the number of brochures and y represents the total cost. The total cost for 35 brochures is $41.45. The total cost for 65 brochures is $55.55. Step 1: Write the ordered pairs (35, 41.45) and (65, 55.55). Step 2: Find the slope. M = StartFraction 55.55 minus 41.45 Over 65 minus 35 EndFraction = 0.47 Step 3: Find the y-intercept to write the equation in slope intercept form. Y minus 55.55 = 0.47 (x minus 35). Y minus 55.55 = 0.47 x minus 16.45. Y = 0.47 x + 39.1.
Answer:
y = 0.47x + 25
y1 = 41.45 and not 55.55
Step-by-step explanation:
Given that:
x = number of brochures
y = total. Cost
Total cost of 35 brochures = $41.45
Total cost of 65 brochures = $55.55
The ordered pairs :
(x1, y1) ; (x2, y2)
x1 = 35 ; y1 = 41.45 ; x2 = 65 ; y2 = 55.55
(35, 41.45), (65, 55.55)
The slope :
Slope (m) = change in y / change in x
m = (y2 - y1) / (x2 - x1)
m = (55.55 - 41.45) / (65 - 35)
m = 14.1 / 30
m = 0.47
The y intercept :
y - y1 = m(x - x1)
y - 41.45 = 0.47(x - 35)
y - 41.45 = 0.47x - 16.45
y = 0.47x - 16.45 + 41.45
y = 0.47x + 25
Lila incorrectly chose 41. 45 as y1
Answer:
C. Lila made an error in Step 3 when she did not use the x- and y-coordinates from the same ordered pair.

Greta uses 2oz of pasta to make 2/3 of a serving of pasta.How many oz of pasta are there per serving
Answer:
3oz of pasta per serving
Step-by-step explanation:
Given parameters:
Number of oz of pastas used = 2oz
Quantity of serving = [tex]\frac{2}{3}[/tex]
Unknown:
Number of oz of pasta per serving = ?
Solution:
To solve this rate problem use;
Number of oz of pasta per serving = [tex]\frac{number of oz of pasta}{number of serving}[/tex]
Number of oz of pasta per serving = [tex]\frac{2}{\frac{2}{3} }[/tex] = 2 x [tex]\frac{3}{2}[/tex] = 3oz of pasta per serving

Use the provided information to write the standard form equation of the parabola.
Opens up or down, and passes through (8,0), (13,-5), and (12,0)
Answer:
f(x) = -x² + 20x - 96Step-by-step explanation:
Parabola f(x) = ax² + bx + c passing through points (8,0) and (12,0) means that 8 and 12 are its root and (x-8) and (x-12) are its factors
So we get:
f(x) = a(x - 8)(x - 12)
The parabola passes through point (13, -5) that means if x=13 then f(x)=-5
So:
-5 = a(13 - 8)(13 - 12)
-5 = a(5)(1)
-5 = 5a
a = -1 {<0 so parabola opens down}
Therefore:
f(x) = -(x - 8)(x - 12)
And expanding:
f(x) = -(x² - 12x - 8x + 96)
So the standard form equation of the parabola:
f(x) = -x² + 20x - 96
