Answer:

All you have is the y intercept ( the point at which the graph crosses the y-axis

Step-by-step explanation:

but you need further information

Lets suppose y= mx + c , you know that y = -2 at a certain point.

-2 = mx + c

to calculate the slope m , you need to know 2 points (x1,x2) , (y1, Y2)

Answer:

y = (1/2)x - 3 Answer A is closest.

Step-by-step explanation:

Two points on the line are (0, -3) and (4, -1). Notice that I've intentionally chosen "nice" points whose coordinates are integers; this makes the math easier. The point (1, -5/2) is also on the line if you want to use it, but the math's a bit more complicated.

Going from (0, -3) to (4, -1), x increases by 4 and y increases by 2. Hence, the slope of this line is m = rise / run = 2/4, or m = 1/2.

The slope-intercept formula for the equation of a straight line is the most convenient to use here, since we can tell immediately from the graph that the y-intercept is (0, -3):

y = (1/2)x - 3

Answer A should be y = (1/2)x - 3 for improved legibility. 1 2 x is not correct as a way to express (1/2)x.

I need to know if A and C is right or not and i need help with B

mote1985 [20]

B: enclosing rectangle is 9×6=54. Then subtract 2 triangles tha together are 6x7=42. 54-43=12.

C. seems to me just 6x4=24.

Answer:

1766.3

Step-by-step explanation:

V=4 /3πr^3

= 4/3(3.14)(7.5)^3

= 4/3(3.14)(421.88)

= 4/3(1324.69)

= 1766.25

= 1766.3

I hope this is right!

Write an equation of the translated function of the parent function f(x)=|x| with the following transformations:

MrRa [10]

Answer:

Option b

Step-by-step explanation:

To write the searched equation we must modify the function f (x) = | x | in the following way:

1. Do y = f(x + 4)

This operation horizontally shifts the function f(x) = | x | by a factor of 4 units to the left on the x axis.

y = | x +4 |

2. Do $y = f (\frac{1}{4}x)$

This operation horizontally expands the function f (x) = | x | in a factor of 4 units. $y = |\frac{1}{4}x + 1|$

3. Do $y = f(x)-4$

This operation vertically shifts the function f (x) = | x | by a factor of 4 units down on the y-axis.

$y = |\frac{1}{4}x +1| -4$

4. After these transformations the function f(x) = | x | it looks like:

$f(x) = |\frac{1}{4}x +1| -4$

Therefore the correct option is option b. You can verify that your vertex is at point (-4, -4) by making f (-4)

$f(-4) = |\frac{1}{4}(-4) +1| -4 = -4$

I need help is it A B C Or D

Natural selection <span>is the process where organisms are more likely to reproduce. When they reproduce, they pass on traits to the next generation. Over time this process allows organisms to adapt to their environment. Giving what natural selection means, I believe the answer is D. Evolution does NOT always improve organisms.

I hope this helps:)</span>
