Answer:

(10, 3)

Step-by-step explanation:

Solve by Substitution

2x − 4y = 8 and 7x − 3y = 61

Solve for x in the first equation.

x = 4 + 2y 7x − 3y = 61

Replace all occurrences of x with 4 + 2y in each e quation.

Replace all occurrences of x in 7x − 3y = 61 with 4 + 2y. 7 (4 + 2y) − 3y = 61

x = 4 + 2y

Simplify 7 (4 + 2y) − 3y.

28 + 11y = 61

x = 4 + 2y

Solve for y in the first equation.

Move all terms not containing y to the right side of the equation.

11y = 33

x = 4 + 2y

 Divide each term by 11 and simplify.

y = 3

x = 4 + 2y

Replace all occurrences of y with 3 in each equation.

Replace all occurrences of y in x = 4 + 2y with 3. x = 4 + 2 (3)

y = 3

Simplify 4 + 2 (3).

x = 10

y = 3

The solution to the system is the complete set of ordered pairs that are valid solutions.

Answer:1/2

Step-by-step explanation: that's it

Answer:

Step-by-step explanation:

Slope means x there are many ways to find the slope like using the slope formula y2-y1/x2-x1  or using rise over run

Hope this help :)

Answer:

Rise over run

Step-by-step explanation:

So what the Rise is, is the point on which the line is persicly on point with they grid of your graph / how high also the distance on the  y axis. The run is the how far also known as the x axis.

so if we had a slope of 2/3

it would be a posative slope it wod go up 2 and to the right 3 to the next intersection of the y ad the x axis'

Answer: 10/3 every hour

The rate the water level is rising is 3 feet and 4 inches per hour.

Answer:

2sqrt(14)*i

Step-by-step explanation:

(sqrt(-56))

since theres a negative in it we know there will be an i in the answer.

We need to find two numbers that multiple to 56 with at least one of them being a perfect sqaure

7*8  doesn't work

4*14 = 56

ok sqrt(4) = 2

can't take the sqaure of (14)

so we are left with

2sqrt(14)*i <---remember from before?

Answer:

6% of 153 is 9.18 and thats the answer

Answer:

9.18 is 6% of 153

Step-by-step explanation:

p/100 x 153 = 9.18

100/153 x p/100 x 153 = 100/153 x 9.18

100/153 x p/100 x 153 = 918/153

p=6

Answer: C

Step-by-step explanation:

Answer: x=12

Step-by-step explanation:

The Pythagorean theorem is a²+b²=c². A and b are the legs, and c is the hypotenuse. Since we are only given the length of a leg and hypotenuse, we fill in what we have and solve for a.

a²+16²=20²          [exponent]

a²+256=400        [subtract both sides by 256]

a²=144                  [square root both sides]

a=12

Now, we know the missing leg, x=12.

Answer:

y = -2x + 7

Step-by-step explanation:

In a equation thats parallel to y = -2x + 5, we have the same slope but different y intercepts (b).

SO we plug in point (3, 1) into y = mx + b

y = -2x + b

1 = -2(3) + b

1 + 6 = b

b = 7

So just plug in b back into the equation

y = mx + b

y = -2x + 7

Answer:

Step-by-step explanation:

y= -2x + 7

using point-slope formula:

y - y1 = m(x - x1)

Substitute:

y - 1 = m(x - 3)

Now, what is m and how do we find it?

m represents the slope. To find the slope in this circumstance, we have to look at the equation that we were given in the problem.

y= -2x + 5

Since we are trying to find a line parallel to this equation, we will be using the same slope that this uses.

The slope in the equation is -2.

Let’s substitute -2 for m.

y - 1 = -2(x - 3)

Now distribute:

y - 1 = -2x +6

Add 1 to both sides:

y = -2x + 7

Now we have an equation in slope-intercept form that is parallel to y= -2x + 5 and runs through the point (3, 1).

Answer:

f < -6

Step-by-step explanation:

3f + 1 < 2f - 5

Subtract 2f from both sides

f + 1 < - 5

Subtract 1 from both sides

f < -6

Answer:

f<-6

Step-by-step explanation:

3f<2f-6

f<6

Answer:

La pregunta esta incompletea porque no incluye el angulo de Raul y el angulo de Blas. Busque un ejemplo similar y encontre que el angulo de Blas es 60° y el de Raul es 45°. Suponiendo que ambos midieron el angulo desde el suelo:

tangente 60° = altura / (41 - d)

tangente 45° = altura / d

altura = (41 - d) · tangente 60°  = (41 - d) · 1.73205

altura = d · tangente 45° = d · 1

d = 71.01408 - 1.73205d

2.73205d = 71.01408

d = 71.01408 / 2.73205 = 25.993 ≈ 26 metros

sustituimos:

altura = d · tangente 45° = 26 · 1 = 26 metros

La altura del generador es de 26 metros
