Martine spent LaTeX: \frac{2}{3}2 3 of her money on a book. She has $6.50 left. How much did she spend on the book?

Answer:

The equation of line perpendicular to given line passing through (3,4) is:

[tex]y = -\frac{3}{2}x+\frac{17}{2}[/tex]

Step-by-step explanation:

Given equation of line is:

[tex]4x - 6y + 7 = 0[/tex]

Given equation is in standard form. It has to be converted into slope-intercept form to extract slope from the equation.

So,

[tex]4x+7 = 6y\\6y=4x+7\\\frac{6y}{6} = \frac{4x+7}{6}\\y = \frac{4}{6}x+\frac{7}{6}\\y=\frac{2}{3}x+\frac{7}{6}[/tex]

The standard form of slope-intercept form of equation is:

[tex]y=mx+b[/tex]

Here, the co-efficient of x is the slope of the line.

So the slope of given line is: 2/3

m = 2/3

The product of slopes of two perpendicular lines is -1

Let m1 be the slope of line perpendicular to given line

Then

[tex]m.m_1 = -1\\\frac{2}{3} . m_1 = -1\\m_1 = -1*\frac{3}{2}\\m_1 = -\frac{3}{2}[/tex]

The equation of perpendicular will be:

[tex]y = m_1x+b[/tex]

Putting the value of slope

[tex]y = -\frac{3}{2}x+b[/tex]

To find the value of b, putting (3,4) in the equation

[tex]4 = -\frac{3}{2}(3)+b\\4 = -\frac{9}{2}+b\\b = 4+\frac{9}{2}\\b= \frac{8+9}{2}\\b=\frac{17}{2}[/tex]

So the equation of line perpendicular to given line passing through (3,4) is:

[tex]y = -\frac{3}{2}x+\frac{17}{2}[/tex]

Answer:

A. 3.794 x 10^6

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step one:

given data

Principal= $2,200

SImple interest =$528

Time = 2years

Rate = ?

Required:

Rate R

The simple interest is expressed mathematically as

SI=PRT/100

substitute we have

528=2200*R*2/100

cross multiply

528*100=2200R

divide both sides by 2200

R=52800/2200

R=24%

Answer/Step-by-step explanation:

2. Using two pairs of values, (0, 59) and (2,000, 51),

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{51 - 59}{2,000 - 0} = \frac{-8}{2,000} = -\frac{1}{250} [/tex]

3. The y-intercept is the value of y when x = 0. Thus, x = 0, when y = 59. Therefore,

y-intercept (b) = 59

4. To write an equation in slope-intercept form, simply substitute m = -¹/250, and b = 59, in [tex] y = mx + b [/tex]

✅[tex] y = -\frac{1}{250}x + 59 [/tex]

5. Substitute x = 5,000 in [tex] y = -\frac{1}{250}x + 59 [/tex].

[tex] y = -\frac{1}{250}(5,000) + 59 [/tex]

[tex] y = -20 + 59 [/tex]

[tex] y = 39 [/tex]

At an altitude of 5,000 ft, temperature would be 39°F

Answer:

9

Step-by-step explanation:

The first step is the stuff in the parenthesis which equals to 1/2(18). The next step is to multiply 18 by 1/2. That is super simple because it is just taking one half of 18 which is 9. Plz vote brainliest

Answer:

x intercept: (-1/7, 0) or (.14, 0)

y intercept: (0, 1/4) or (0, .25)

Step-by-step explanation:

Answer:

x- (−0.142857142857143,0)

y- (0, .25)

Step-by-step explanation:

The x-intercept:

Plug y=0 into the equation and solve the resulting equation 7x−5=−6 for x

(−1/7,0) = (−0.142857142857143,0)

The y-intercept:

Plug x=0 into the equation and solve the resulting equation −5=4y−6 for y

(0,1/4) = (0, .25)

Answer:

z = 3[tex]\sqrt{13}[/tex]

Step-by-step explanation:

Using the altitude- on- hypotenuse theorem

( leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )

z² = 9 × (9 + 4) = 9 × 13 = 117 ( take square root of both sides )

z = [tex]\sqrt{117}[/tex]

  = [tex]\sqrt{9(13)}[/tex]

  = [tex]\sqrt{9}[/tex] × [tex]\sqrt{13}[/tex]

  = 3[tex]\sqrt{13}[/tex]

Answer:

Slope is 2; y-intercept is (0,-6)

Step-by-step explanation:

Slope intercept form looks like 3y = 2x - 6

In the equation y=mx+b, M is always the slope, and B is always the y-intercept. Therefore if you look back at the problem the slope number should be in front of the x which makes it 2. Since the y-intercept is always b, y = -6.

Slope or m = 2; y-intercept is (0,-6)

Answer:

y = [tex]\frac{2}{3}[/tex] x - 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

- 2x + 3y = - 6 ( add 2x to both sides )

3y = 2x - 6 ( divide all terms by 3 )

y = [tex]\frac{2}{3}[/tex] x - 2 ← in slope- intercept form

with slope m = [tex]\frac{2}{3}[/tex] and y- intercept c = - 2

Answer:

Gerry arrived at the bus station at 12:30 P.M.

Step-by-step explanation:

From noon and 5:00 P.M. there are 5 hours.

Gerry, Dale, and Pat arrived at the bus stop within that interval, which means the sum of the times elapsed between their arrival times must be 5.

4 out of the 5 hours elapsed since Gerry and Dale's arrivals. This means there is only one hour left for twice x.

If twice x is one hour, then x is half an hour. Thus, the complete sequence of arrivals is:

Gerry arrived at the bus station at 12:30 P.M.

Dale arrived at the bus station at 4:30 P.M.

Pat arrived at the bus station at 5:00 P.M.

Step-by-step explanation:

Answer:

x is 50

y is 55

Step-by-step explanation:

Let us start working with the second patio

At any point in time, the total measure of the angles of a triangle is 180

Thus in the second patio;

x + 20 + 50 + 60 = 180

x + 130 = 180

x = 180-130

x = 50

In the first patio;

x + 10 + y + 15 + 70 = 180

substitute 50 for x

50 + 10 + y + 65 = 180

60 + 65 + y = 180

y = 180-60-65

y = 55

Km = miles x 1.609

240 x 1.609 = 386.24 km

The answer is D. 386 kilometers

Answer:

D. 386

Step-by-step explanation:

If we know that we have 240 miles then we need to find the Km/m which is 1.60934 Km to 1 M, and we have the equation y= 1.60934(x), y bing the total amount of Km, or in other words, your answers, and x is the miles. Now change that x into 240 so now you have y= 1.60934(240) which comes out to 386.2416 Km or 386Km as seeing you have to round tho the nearest whole number.
