Write and solve an equation to find the value of x

Answer:

1. y = 4x - 27

2. y = -4x - 15

Step-by-step explanation:

If two lines are parallel, then they have the same slope. So, the slope of the line we are looking for needs to be 4. We can start by writing a point-slope equation:

y - y1 = m(x - x1)

We can substitute the values we have, the point we are using is (8, 5) because it needs to be on the line:

y - 5 = 4(x - 8)

We can distribute:

y - 5 = 4x - 32

y = 4x - 27

We are not given the slope-intercept form, so we must divide both sides by two to get it:

y = 1/4 x + 8

A perpendicular line has the slope that is the negative reciprocal of the one that is given. So, the slope of the line would be - 4. We can start by writing a point-slope equation:

y - y1 = m(x - x1)

We can substitute the values we have, the point we are using is (-5, 5) because it needs to be on the line:

y - 5 = -4(x + 5)

We can distribute:

y - 5 = -4x - 20

y = -4x - 15

Answer:

1) 3 miles/h

2) 3 miles

Step-by-step explanation:

6 miles/2h = 3 miles/h

4h = 12 miles

3h = 9 miles

12 - 9 = 3

Answer:

1 is 3 miles an hour and 2 is 3 miles

Step-by-step explanation:

A) = 54 so it is wrong

B) = 78 so it is wrong

C) = -2 so it is right!

No need to do D since we already found the correct answer.

I hope I helped! :)

Answer:

If s₃ is the length of the 3rd side, the possible values are in the interval.

5 < s₃ < 19

Step-by-step explanation:

For a triangle, we know that the sum of any two sides is always larger than the other side.

So if a triangle has 3 sides:

s₁, s₂, and s₃, we have:

s₁ + s₂ > s₃

s₁ + s₃ > s₂

s₂ + s₃ > s₁

In this case, we know that two sides are:

s₁ = 7

s₂ = 12

And we want to find the possible values of s₃.

Then if we use the above inequalities, we get:

7 + 12 > s₃

7 + s₃ > 12

12 + s₃ > 7

With the first one we get:

19 > s₃

Now we can rewrite the other two as:

s₃ > 12 - 7 = 5

s₃ > 7 - 12 = -5

The first one is more restrictive than the second:

s₃ > 5 > -5

So we can use only the first one.

Then the two inequalities are

s₃ > 5

s₃ < 19

Then the range is:

5 < s₃ < 19

This means that any value between 5 and 19 can be a possible length of the third side (5 and 19 are not possible lengths)

Answer:

4x=y

Step-by-step explanation:

4x=y is your answer because if x is 5, like in the table, then 4(5) would equal 20, which is the y-value. It also works for every number in the table.

Hope this helps.

h²=p²+b²

h²=20²+21²

h=√841

h=29miles

he would walk 29 miles on the way back

Answer:

The answer is "Choice d".

Step-by-step explanation:

Please find the complete question in the attached file.

Although Simone read today, a first written driver test rate of failure is 60 percent to Arizona.

Range of population = p = 0.60 . Simone assumes the Arizona average would be below 60%. She selects an SRS of 50, but she discovers 27 have failed their first published driver's test (sample size n= 50).

Now 200 simulated experiments were conducted to determine when that offers compelling proof which Arizona has a failure rate of less than 60%. The hypothesis of Simone is p = 60% and p < 60% where p = true share of Arizona pilots who fail the very first test of a written pilot.

The evaluated P-value of this experiment is 0.035 based on the results of the simulation. α = 0.01 

Whereas if p-value < α = degree of significance, we reject the null hypothesis. p-value [tex]= 0.035 > 0.01[/tex]

15 x 8 x 11 is greater than one yard of fabric

Step-by-step explanation:

Volume of a rectangular prism = length x width x height

15 x 8 x 11 = 1320 in^3

1 yard = 36 inches

1320 is greater than 36 inches. she does not have enough yard of fabric

Answer:

Step-by-step explanation:

We can set up the following proportion and solve for length ([tex]\ell[/tex]):

[tex]\frac{2}{5}=\frac{\ell}{13},\\\\\ell=\frac{2\cdot 13}{5}=\frac{26}{5}=\boxed{5.2\:\mathrm{in}}[/tex]

Answer:

430.93 miles (rounding to the nearest hundredth)

Step-by-step explanation:

s = 93 log(d) + 65

310 = 93 log(d) + 65

245 = 93 log(d)

2.634408602 = log(d)

10^2.634408602 = 10^log(d)

430.9318583 = d

Therefore, if the speed of the tornado is 310 mph, then its distance is about 430.93 miles.

Answer:

11 sq units

Step-by-step explanation:

(6×4) - ½(6×1 + 4×3 + 2×4)

= 24 - ½(6+12+8)

= 24 - ½(26)

= 24-13

= 11 sq units

Answer:

you find the area of a square by multiplying the side length by the side length. For example, the side length of a square is 10, then the area of the square would be 10 * 10= 100, the area would have been 100. A=l*l

I dont know what other shapes do you need so i would tell you how to find the area of a triangle. you find it by multiplying the base and the height and times it by 1/2.  A=1/2*b*h

Answer:

Finding Area Of Shapes

Step-by-step explanation:

The formula for solving for area of a square is A= S x S which basically means Area = Side multiplied by side, S is the length of each side of the square. With squares, it's much easier to find the length because it's all going to be the same on each side so you multiply the number by its self to get your answer.

Example :  

8 x 8 = 64

So the area of the square would be 64 if each side were 8 because you're going to multiply using 2 sides and multiply that number by itself.

Hope this helps let me know if you need any other help!

Answer:

184

Step-by-step explanation:

V=lwh

(4)(5)(2) = 40

(7)(4)(3) = 84

(2)(5)(4) = 60

40 + 84 + 60 = 184

Step-by-step explanation:

a^2 + 2(b - 6) - 17. a = -7 b = 2

= (-7)^2 - 2(2 - 6) - 17

= 49 - 4 + 12 - 17

= 40

Answer:

87.92 inches cubed or 87.92 in.^3

Step-by-step explanation:

The base of a cylinder is a circle, so we need to calculate the area of the circle first. The equation for the area of a circle is:

area (a) = pi * r^2 =3.14*2*2 =12.56sq.inches

again,

volume of cylinder = area of the base * the height

= 12.56 * 7

= 87.92 inches cubed or 87.92 in.^3

[tex] \sqrt{25} = 5 \\ \sqrt{16 } = 4 \\ \sqrt{49} = 7[/tex]

5+4-7 = 9-7 = 2

Our Answer 2

Answer:

The answer is 2

Step-by-step explanation:

√25 = 5

√16 = 4

√49 = 7

Now,

√25 + √16 - √49

5 + 4 - 7

9 - 7 = 2

Thus, The answer is 2
