Y= -4x + 1 y= -2x - 3

AysviL [449]

Answer:

x = 2 , y = -7

Step-by-step explanation:

Solve the following system:

{y = 1 - 4 x | (equation 1)

{y = -2 x - 3 | (equation 2)

Express the system in standard form:

{4 x + y = 1 | (equation 1)

{2 x + y = -3 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{4 x + y = 1 | (equation 1)

{0 x+y/2 = -7/2 | (equation 2)

Multiply equation 2 by 2:

{4 x + y = 1 | (equation 1)

{0 x+y = -7 | (equation 2)

Subtract equation 2 from equation 1:

{4 x+0 y = 8 | (equation 1)

{0 x+y = -7 | (equation 2)

Divide equation 1 by 4:

{x+0 y = 2 | (equation 1)

{0 x+y = -7 | (equation 2)

Collect results:

Answer: {x = 2 , y = -7

Answer:

p-value = 0.369

Step-by-step explanation:

Test of hypothesis which has its the alternative hypothesis as Ha:μ1−μ2≠0 is a two tailed test. Therefore, P-value for a two-tailed test with test statistic t≈−0.90 and the number of degrees of freedom = 208

P-value = 2 X P( t(208) < - 0.90)

= 2 X 0.1846

= 0.369

Answer:

Step-by-step explanation:

the mean would be appropriate measure of center to describe the data shown in the histogram because the data is symmetrical.A symmetric histogram is a distribution in which the 2 halves appear to be the same on both sides.

Answer:

The range in the average rate of change in temperature of the substance is from a low temperature of $-22^{\circ}$ to a high of $16^{\circ}$ .

Step-by-step explanation:

In the sinusoidal function $y=a\sin(b(x-c))+d$ , $|a|$ represents the amplitude and $y=d$ represents the equation of the midline.

By definition sinusoidal functions ebb and flow with respect to this midline. Therefore, the minimums must occur at $y=d-|a|$ and the maximums must occur at $y=d+|a|$ .

Thus, the minimum, or low, occurs at $y=-3-|-19|=-3-19=\boxed{-22}$ and the maximum, or high, occurs at $y=-3+|-19|=-3+19=\boxed{16}$ .
