Find the slope and the y-intercept of the graph of the linear equation y=−1/7x+2.
HELP THIS IS SO IMPORTANT I DONT HAVE MUCH TIME! D:
Answer:
slope equals negative 1/7 and the y inter is 2
Please solve, thank you. If you don’t know, don’t answer.
Answer:
y>5/3-3
Step-by-step explanation:
the two points graphed are (0,-3) and (3,-2)
what you're trying to find is the inequality between y and the slope, so first you need to find the slope
the formula for finding the slope is (y2-y1)/(x2-x1)
substitute your two points for your formula:
-2-3=-5
3-0=0
5/3 is your slope
your y intercept is -3 and we know this because it is the location of y when x=0
so your slope is 5/3 and your y intercept is 3, so now you decide howto write the inequality .
the shaded part is above the line and the line is dotted, so how you know to use the > sign
put it all together and you get y>5/3-3
The first two terms in an arithmetic progression are -2 and 5. The last term in the progression is the only number in the progression that is greater than 200. Find the sum of all the terms in the progression.
Given:
The first two terms in an arithmetic progression are -2 and 5.
The last term in the progression is the only number in the progression that is greater than 200.
To find:
The sum of all the terms in the progression.
Solution:
We have,
First term : [tex]a=-2[/tex]
Common difference : [tex]d = 5 - (-2)[/tex]
[tex]= 5 + 2[/tex]
[tex]= 7[/tex]
nth term of an A.P. is
[tex]a_n=a+(n-1)d[/tex]
where, a is first term and d is common difference.
[tex]a_n=-2+(n-1)(7)[/tex]
According to the equation, [tex]a_n>200[/tex].
[tex]-2+(n-1)(7)>200[/tex]
[tex](n-1)(7)>200+2[/tex]
[tex](n-1)(7)>202[/tex]
Divide both sides by 7.
[tex](n-1)>28.857[/tex]
Add 1 on both sides.
[tex]n>29.857[/tex]
So, least possible integer value is 30. It means, A.P. has 30 term.
Sum of n terms of an A.P. is
[tex]S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]
Substituting n=30, a=-2 and d=7, we get
[tex]S_{30}=\dfrac{30}{2}[2(-2)+(30-1)7][/tex]
[tex]S_{30}=15[-4+(29)7][/tex]
[tex]S_{30}=15[-4+203][/tex]
[tex]S_{30}=15(199)[/tex]
[tex]S_{30}=2985[/tex]
Therefore, the sum of all the terms in the progression is 2985.

Answer:
w ≥ 66
Step-by-step explanation:
You know that anything less than 66 would not cause any effect, so you need something that is exactly 66 or more than 66 for the airbag to deploy.
Thus, w ≥ 66
≥ means that w is more than or equal to 66. (66 and above)
< means that w is less than 66. (65 and below)
> means that w is more than 66. (67 and above)
≤ means that w is less than or equal to 66. (66 and below)
Answer:
w<66 is the answer i believe

What percent of 51 is 127.5?
(Those are two questions but like on the same thing )
Answer:
first: 27.5
second: 250%
Step-by-step explanation:
first: 17.16 ÷ 62.4% = 0.275, 27.5
second: 51 ÷ 127.5 = 0.4, 40%,
100% ÷ 40%, = 2.5, 250%

the depth of water at the end of a boat dock can be modeled by a senusoidal function Y=Asin [B(r+C) ]+D where y represents the depth in feet of the water, hours after midnight on a certain day, the depth is 10 feet at low tide at 6 am and 18 feet at high tide at noon find the amplitude and midline for the general sine function that can be used to model the water's depth.
Answer:
A=4 ft
Midline: y=14
Step-by-step explanation:
When talking about sinusoidal waves, we know the amplitude will be the distance between the midline and the highest or lowest point of the graph. This can be found by first, finding the distance between the lowest point and the highest point:
d= 18ft - 10ft = 8ft
and divide this distance into 2:
[tex]A=\frac{8}{2}[/tex]
A= 4 ft
in order to find the midline, we need to figure the midpoint between the highest and lowest value. We can do so by using the following formula:
[tex]Midpoint=\frac{high+low}{2}[/tex]
so:
[tex]Midpoint=\frac{18+10}{2}[/tex]
Midpoint = 14
so the midline is located at the line:
y=14

a sequence has a first number of 3 and a half common difference of 4 what is the recursive rule of nth term
Answer:
[tex]f(n) = f(n-1) + 8[/tex] for [tex]n > 1[/tex]
Step-by-step explanation:
Given
[tex]f(1) = 3[/tex] -- First Term
[tex]\frac{1}{2}d = 4[/tex] --- half common difference
Required
Find the recursive rule
First, we calculate the common difference
[tex]\frac{1}{2}d = 4[/tex]
Multiply through by 2
[tex]2 * \frac{1}{2}d = 2 * 4[/tex]
[tex]d = 8[/tex]
The second term of the sequence is:
[tex]f(2) = 3 + 8 = 11[/tex]
The third term is:
[tex]f(3) = 11 + 8 = 20[/tex]
So, we have:
[tex]f(1) = 3[/tex]
[tex]f(2) = 3 + 8[/tex]
Substitute f(1) for 3
[tex]f(2) = f(1) + 8[/tex]
Express 1 as 2 - 1
[tex]f(2) = f(2-1) + 8[/tex]
Substitute n for 2
[tex]f(n) = f(n-1) + 8[/tex]
Similarly:
[tex]f(3) = 11 + 8[/tex]
Substitute f(2) for 11
[tex]f(3) = f(2) + 8[/tex]
Express 2 as 3 - 1
[tex]f(3) = f(3-1) + 8[/tex]
Substitute n for 3
[tex]f(n) = f(n-1) + 8[/tex]
Hence, the recursive is:
[tex]f(n) = f(n-1) + 8[/tex] for [tex]n > 1[/tex]

Answer:
x = 7
Step-by-step explanation:
The midsegment of a trapezoid is calculated as
midsegment is lalf the sum of the 2 parallel bases, that is
4x + 3 = [tex]\frac{25+37}{2}[/tex] = [tex]\frac{62}{2}[/tex] = 31 ( subtract 3 from both sides )
4x = 28 ( divide both sides by 4 )

Answer:
The scale factor for the dilation of rectangle ABCD to rectangle MNOP is [tex]\frac{3}{4}[/tex] ⇒ B
Step-by-step explanation:
In similar rectangles, their corresponding dimensions are proportional, which means [tex]\frac{L_{1} }{L_{2}}[/tex] = [tex]\frac{W_{1} }{W_{2}}[/tex] , where L is the length and W is the width
∵ Rectangle ABCD is similar to rectangle MNOP
∴ Their dimensions are proportional
∵ The dimensions of rectangle ABCD are 6 m, 14 m
∴ L[tex]_{1}[/tex] = 14 and W[tex]_{1}[/tex] = 6
∵ The dimensions of rectangle MNOP are 4.5 m, 10.5 m
∴ L[tex]_{2}[/tex] = 10.5 and W[tex]_{2}[/tex] = 4.5
∵ The rectangle MNOP is the image of rectangle ABCD after dilation
→ To find the scale factor of dilation find the ratio between the
corresponding dimensions in the two rectangles (image/pre-image)
∵ [tex]\frac{L_{2} }{L_{1}}[/tex] = [tex]\frac{10.5}{14}[/tex] = [tex]\frac{3}{4}[/tex]
∵ [tex]\frac{W_{2} }{W_{1}}[/tex] = [tex]\frac{4.5}{6}[/tex] = [tex]\frac{3}{4}[/tex]
∴ The scale factor for the dilation is [tex]\frac{3}{4}[/tex]
The scale factor for the dilation of rectangle ABCD to rectangle MNOP is [tex]\frac{3}{4}[/tex]

The coordinate of A' is (-5, 3)
Option b is true.
Given that;
The coordinate of A is (3, 5)
And, To rotate ABCD 90° counterclockwise about the origin.
We have to find the coordinate of A'.
What is Rule of 90° counterclockwise rotation about the origin?
If we rotate 90° counterclockwise about the origin then the coordinate A (x, y) become A' (-y, x).
The coordinate of A is (3, 5).
By the rule of 90° counterclockwise rotation about the origin;
We get, After rotation 90° counterclockwise rotation about the origin the coordinate A (3, 5) become A' (-5, 3)
