What is the equation of the line parallel to line l that passes through point (3,3)

Mathematics

OverLord2011 [107]2 years ago
5 0

Answer:

Step-by-step explanation:

Let the equation if the line be y = mx + c

since the line is parallel to y = (smt-your question isn't complete), their gradients/slope must be the same (aka m = __)

sub (3, 3):

3 = __(3) + c

c = __

therefore, the equation of the line is y = __x + __

This is a question on coordinate geometry. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)

Evaluate the expression for s = -15. -S= ​
Oxana [17]

Answer:

  -S = 15

Step-by-step explanation:

You are asked to find the opposite of the given value.

<h3>Opposite</h3>

The opposite of an integer value is obtained by changing its sign.

  S = -15

  -S = -(-15) = 15

__

<em>Additional comment</em>

Equivalently, you are multiplying by -1. The product of an even number of minus signs is a plus sign. We usually don't write the plus sign for a numerical value.

4x - 2y = 5<br> y= 2x + 10
Helga [31]

Answer:

There is no solution

Step-by-step explanation:

4x - 2y = 5 --> 4x - 2(2x + 10) = 5

4x - 4x  - 20 = 5

4x - 4x -25 = 0

Final answer is -25 = 0 and so therefor it is no solution

An article presents a study of the failure pressures of roof panels. A sample of 15 panels constructed with 8-inch nail spacing
wariber [46]

Answer:

There is sufficient evidence to conclude that six inches spacing has a higher mean failure pressure than 8 inches

Reject H_0\ at\ 5% level of significance

Step-by-step explanation:

From the question we are told that:

Sample size 1 n_1=15

Spacing 1 s_1=8

Mean 1 \=x_1=8.48

Standard deviation 1 \sigma_1=0.96 kPa

Sample size 2 n_2=16

Spacing 2 s_2=6

Mean 1 \=x_1=9.93

Standard deviation 1\sigma_1=1.02 kPa

Generally the hypothesis is mathematically given as

Null H_0:\mu_1-\mu_2

Alternative H_a:\mu_1\mu_2

Generally the equation for pooled estimate is mathematically given by

  S=\sqrt{\frac{(n_1-1)\sigma_1^2+(n_2-1)\sigma_2^2}{n_1+n_2-2} }

Therefore

  S=\sqrt{\frac{(15-1)0.96^2+(16-1)1.02^2}{15+15-2} }

 S=0.9905

Generally the equation for test statistics is mathematically given by

 t=\frac{\=x_1+\=x_2}{S\sqrt{\frac{1}{n _1}+\frac{1}{n_2}}}

 t=\frac{\=8.48-9.93}{0.9905\sqrt{\frac{1}{15}+\frac{1}{15}}}

 t=-4.00091

Therefore From table

 P value=P(t_{15+15-2}=4.00091)

 P value=0.00041918

 P

Therefore

There is sufficient evidence to conclude that six inches spacing has a higher mean failure pressure than 8 inches

Reject H_0\ at\ 5% level of significance
