what’s the slope of (6,6) and (1,9)
Answer:
-3/5
Step-by-step explanation:
always remember rise by run. subtract the second y value from the first (9 minus 6) and the same with the x values (1-6). rise is y axis and run is x axis. therefore, you get 3/-5 or -3/5. (because 9-6 is 3 for the numerator and 1-6 is -5 for the denominator)
Paul, Colin and Brian are waiters.
One night the restaurant earns tips totalling £77.40.
They share the tips in the ratio 2:3:4.
How much more does Brian get over Paul?
=====================================================
Explanation:
x is some positive number such that the earnings of Paul, Collin, and Brian are 2x, 3x and 4x in that order
The ratio 2x:3x:4x reduces to 2:3:4 when we divide all parts by x
The total amount of tips was 77.40 pounds
This means,
(Paul's Share)+(Collin's Share)+(Brian's Share) = Total Tips
(2x)+(3x)+(4x) = 77.40
9x = 77.40
x = 77.40/9
x = 8.6
Use that x value to find each of their share of tips
Paul's Share = 2x = 2*8.6 = 17.20 poundsCollin's Share = 3x = 3*8.6 = 25.80 poundsBrian's Share = 4x = 4*8.6 = 34.40 poundsAs a check, note how 17.20+25.80+34.40 = 77.40
The last step is to subtract the values for Brian and Paul
34.40 - 17.20 = 17.20
Brian earned £17.20 more in tips compared to Paul.

Determine if the Mean Value Theorem for Integrals applies to the function f(x) = 3 - x2 on the interval the closed interval from 0 to the square root of 3 . If so, find the x-coordinates of the point(s) guaranteed by the theorem
Answer: Yes, Mean Value Theorem for Integrals applies for the function [tex]f(x)=3-x^{2}[/tex] and values of x are 1 and -1
Step-by-step explanation: Mean Value Theorem for Integrals states that if a function is continuous on a closed interval, there is a value c on the interval such that
[tex]f(c)=\frac{1}{b-a} \int\limits^b_a {f(x)} \, dx[/tex]
where a and b are the closed interval given
As the graph of [tex]f(x)=3-x^{2}[/tex] shown below, the function is continuous on the interval [0,[tex]\sqrt{3}[/tex]], so the theorem applies.
To find the x-coordinates, first determine value of f(c) at [0,[tex]\sqrt{3}[/tex]]:
[tex]f(c)=\frac{1}{\sqrt{3} -0} \int\limits {3-\sqrt{x^{2}} } \, dx[/tex]
[tex]f(c)=\frac{1}{\sqrt{3}}[3x-\frac{x^{3}}{3} ][/tex]
[tex]f(c)=\frac{1}{\sqrt{3}}[ 3\sqrt{3}-\frac{(\sqrt{3})^{3}}{3} ][/tex]
[tex]f(c)=\frac{1}{\sqrt{3} } [2\sqrt{3} ][/tex]
f(c) = 2
The x-coordinates will be:
[tex]f(x)=3-x^{2}[/tex]
[tex]2=3-x^{2}[/tex]
[tex]x^{2}=1[/tex]
[tex]x=\sqrt{1}[/tex]
x = ±1
The values for x guaranteed by the Mean Value Theorem are +1 and -1.
What is the equation in slope-intercept form of the line that crosses the x-axis at (36, 0) and is perpendicular to the line represented by y=−49x+5
Answer:
y = 1/49x

. Solve the equation. -3/4 (x - 3) - 5 = 1/8 (x - 1) *
[tex] \frac{ - 3}{4} (x - 3) - 5 = \frac{1}{8} (x - 1)[/tex]
[tex] \frac{ - 3}{4} x + \frac{9}{4} - 5 = \frac{1}{8} x - \frac{1}{8} [/tex]
[tex] \frac{ - 3}{4} x - \frac{1}{8} x = - \frac{1}{8} - \frac{9}{4} + 5[/tex]
[tex] \frac{ - 6x}{8} - \frac{x}{8} = \frac{ - 1}{8} - \frac{18}{8} + \frac{40}{8} [/tex]
[tex] \frac{ - 6x - x}{8} = \frac{ - 1 - 18 + 40}{8} [/tex]
[tex] \frac{ - 7x}{8} = \frac{21}{8} [/tex]
[tex] - 7x = 21[/tex]
[tex]x = \frac{21}{ - 7} [/tex]
[tex]x = - 3[/tex]

Use the provided information to write the standard form equation of the parabola.
Opens up or down, and passes through (4,-5), (0,3), and (-1,10)
Answer:
f(x) = x² - 6x + 3Step-by-step explanation:
Parabola f(x) = ax² + bx + c passing through point (x₁, y₁) means if x=x₁ then f(x)=f(x₁)=y₁
(0, 3) ⇒ 3=a·0²+b·0+c ⇒ c=3
f(x) = ax² + bx + 3
(4, -5) ⇒ -5 = a·4² + b·4 + 3
-5 = 16a + 4b + 3
-4b = 16a + 8
b = - 4a - 2
(-1, 10) ⇒ 10 = a·(-1)² + b·(-1) + 3
10 = a - b + 3
b = a - 7
a - 7 = - 4a - 2
5a = 5
a = 1
b = 1 - 7 = - 6
So the equation:
f(x) = x² - 6x + 3

Whats the slope of the equation 6x + 8y = 16?
Answer:
-3/4
Step-by-step explanation:
6x+8y=16
(subtract 6x from both sides)
8y=-6x+16
(divide everything by 8)
y=-6/8x+16
(simplify)
y= -3/4x+16
this is now in y=mx+b form. m=slope

Write the equation of the line that has the indicated slope and y-intercept.
Slope = 5; y-intercept = 9
Answer:
slope intercept form: y=5x+9
standard form: x-5/y =-9/5

slope intercept form: y=mx+b, m=slope, b=y-intercept
m= 5, b=9 therefore,
y=5x+9

There are 2.54 centimeters in 1 inch. There are 100 centimeters in 1 meter. How many inches are there in 12 meters
Answer:
1200 centimeters
Step-by-step explanation:
if you have 100 centimeters in 1 meter and there are 12 meters you can just multiply the number of centimeters by 12 or whatever number is needed in this case 12 so when you multiply 12 x 100 you get 1200

Gerald inherited $35,000 from his uncle. He spends $1400 a month. After how many months
will Gerald have less than $2,000?
Answer:
18 months
Step-by-step explanation:
35,000÷18=1944
First, we need to figure out the amounts of months that Gerald has total, with all of the money. So, we divide 35000 by 1400, this leaves us with 25. So, if he keeps spending 1400 per month, it will last him 25 months, but this is not what the question asks, is it? In 25 months, his inheritance will be fully depleted, in 24 months he will have spent 33,600 dollars, meaning he will have 1400 dollars left (35000 - (24 * 1400))and in 23 months, he will have spent 32,200 dollars, meaning that he will have 2800 dollars.
"In 24 months he will have spent 33,600 dollars, meaning he will have 1400 dollars left 35000 - (24 * 1400)"
35000 - (24 * 1400)
24 months
