9th grade math I don’t understand

Mathematics
1 answer:
Tema [17]3 years ago
3 0

Answer:

434

Step-by-step explanation:

Looking at this sequence, we can immediately tell that it is <em>arithmetic</em>, because the terms keep adding up by 9.

Now that we know it is arithmetic, we can use the formula:

t_{n} = t_{1} + (n-1)d

Where tn represents the nth number, t1 represents the first term, and d represents the increasing change.

Plugging in the given values, we have:

t_{48}= 11+(48-1)9\\t_{48}=11+47*9\\t_{48}= 11+423\\t_{48}=434

Use point-slope form to write the equation of a line that passes through the point
solniwko [45]

Answer:

y = -5x - 25

Step-by-step explanation:

Substitute into form of y - y1 = m(x - x1): (Take the point (-7,10) for x1 & y1, m would be the slope)

y - 10 = -5(x -(-7))

y - 10 = -5(x + 7)

y - 10 = -5x - 35

y = -5x - 25

Can someone help me please
Ostrovityanka [42]

Answer:

D

Step-by-step explanation:

as we can easily see, the x-coordinates of all points increased by 7.

so, we need a solution with "x+7". that eliminates B and C.

with that transition (glide) the triangle moved to the right into the 4th quadrant.

and now, as a second step, it needs to move up, above the x-axis, into the 1st quadrant.

and that is a reflection across the x-axis.

a reflection across the y axis would bring it back into the 3rd quadrant, where it started.

so, it is D.
