Answer : Graph D

Question says negative linear relationship. It means the slope is negative.

Option A and C have positive slope because the dots on graph goes up.

So we ignore A and C graph

B and D graphs have negative slope.

Given Correlation coefficient r is close to -0.5

In Graph B the dots are close to one another . It means the correlation coefficient r is close to - 1

Graph D shows a negative linear relationship with a correlation coefficient r close to =-0.5

What is the equation of a parabola with a vertex at (0, 0) and a directrix x = -4?

maks197457 [2]

The general form for this is y^2 = 4ax where a = focus

the directrix is same distabce behind the vertex as focus is in font so focus a = 4

so we have y^2 = 16 x
or
x = (1/16) y^2

Its C

Answer:

LP = 18

Step-by-step explanation:

Given that,

In ΔLPN,

LQ = 6, LM = 11 and MN = 22

We need to find the length of LP.

As QM ║PN, let QP = x

$\dfrac{LQ}{LP}=\dfrac{LM}{LN}\\\\\dfrac{6}{6+x}=\dfrac{11}{11+22}\\\\\dfrac{6}{6+x}=\dfrac{11}{33}\\\\198=66+11x\\\\198-66=11x\\\\132=11x\\\\x=12$

LP = 6+x

= 6+ 12

= 18

Hence, the length of LP is 18.

The temperature at 8:00am is 5 degrees Celsius and increases 2 degrees per hour. Does this equal y=2x+5

Ierofanga [76]

Yes.

y represents the temperature.

x represents the number of hours past 8:00am.
