Answer:
[tex]9x+5y=-20[/tex]
Step-by-step explanation:
[tex]y = \frac{5}{9} x - 4[/tex]
compare with that y=mx+c
where m=slope .
So after comparing we get m=[tex]\frac{5}{9}[/tex]
As the lines are perpendicular
[tex]m1*m2=\ -1[/tex]
[tex]m2 \ =\ \frac{-1}{m1}[/tex]
therefore m2=[tex]\frac{-9}{5}[/tex]
Now from the equation
[tex]y - b = m(x - a )[/tex] this equation passing to the point (-5,5) with m=[tex]\frac{-9}{5}[/tex]
[tex]y-5=\frac{-9}{5} (x+5)\\5y-25=-9x\ -45\\9x+5y=-20[/tex]
Therefore equation is
[tex]9x+5y=-20[/tex]
Choose the graph that correctly corresponds to the equation x = −4.

Jade measured the height of an art frame as 5.23 feet, but the actual height was 6 feet. What is the percent of error in Jade’s measurement?
12.83%
13.55%
14.72%
15.55%
Answer: A
Step-by-step explanation:
Percentage error is error divided by actual value multiply by 100. That is,
%error = error/actual value × 100
If Jade measured the height of an art frame as 5.23 feet, where the actual height was 6 feet. Then,
Error = 6 - 5.23 = 0.77
Substitute error = 0.77 and the actual value = 6 into the formula
%error = 0.77/6 × 100
%error = 12.83 %
Therefore, the percent of error in Jade’s measurement is 12.83%
Answer:
12.83
Step-by-step explanation:
took the test got a 100% percent surprisingly ummmm anywaysss....

Find all possible values of the digits Y, E, A, R if YYYY - EEE + AA - R = 1234, and different letters represent different digits.
Answer:
Y=2, E=9, A=1, R=0
Step-by-step explanation:
YYYY starts from thousand
EEE starts from hundred
AA starts from tens
R is a units
So we can have
1000Y+100Y+10Y+Y-100E-10E-E+10A+A-R=1234
1111Y - 111E + 11A - R=1234
Y cannot be greater than 2 and it can't be 1 either because
if Y is 1, we will have a total of one thousand one hundred and eleven (1111) which is less than one thousand two hundred and thirty-four (1234) as from the answer in the question
So, it is safe to say Y=2 in order to have two thousand two hundred and twenty-two(2222)
This means that Y must be 2:
2222-111E+11A-R=1234
In this case, E would have to be 9 to make it possible for this to have a solution, by bringing it down to 1223.
YYYY-EEE
2222-999=1223
1223+11A-R=1234
1223+11=1234
This means that A must be 1 and that R must be 0.
2222
- 999
+11
-0

Answer:
243,729
Step-by-step explanation:
You just need to multiply each number by 3.
I hope this help you :)
Answer:
243, 729
Explanation:
To solve this problem we must first understand what the pattern is in the sequence. Once we understand the pattern, we can then apply it to the final known term to find the next two terms.
Take a look at the sequence given:
1, 3, 9, 27, 81,...
Let's start by figuring out how they got the second term in the sequence. To do that, identify what basic operation and number must be applied. This will reveal the pattern.
1 - first term
3 - second term
1 ? ? = 3
1 × 3 = 3
So, this means the sequence multiplied three to get the next term. Therefore, the pattern should be 'multiply three' to get the next term. Just to be sure the pattern we found is correct, apply it to the given sequence.
1, 3, 9, 27, 81,...
1 × 3 = 3
3 × 3 = 9
9 × 3 = 27
27 × 3 = 81
So, since 'multiply three' every time gives us the next term, the pattern is correct.
Finally, let's continue the pattern to find the next two terms.
81 × 3 = 243
243 × 3 = 729
Therefore, the next two terms in the sequence are 243, 729.
Solve for x in the triangle. Round your answer to the nearest tenth.
Answer:
x = 5.5 to the nearest tenth.
Step-by-step explanation:
Here we have a right triangle with one angle (65 degrees) given. Side x is the "side adjacent to the angle" and is to be found. The hypotenuse is 13.
The cosine function makes use of these three knowns: the angle, the hypotenuse and the adjacent side. Thus:
cos 65 degrees = adj / hyp = x / 13, or
x = 13 cos 65
Evaluating this on a calculator, we get x = 5.49, or x = 5.5 to the nearest tenth.
The measure of angle 3 is 42°
What is the measure of angle 1 in degrees
Answer:
48 degrees
Step-by-step explanation:
Angle 2 is a right angle.
Right angles are 90 degrees.
A line is 180 degrees.
Angle 1, 5, and 2 form a line.
180-90=90
That means that Angles 1 and 5 add up to 90 degrees.
We know that Angle 3 is 42 degrees.
Angle 3 and 5 are Vertical angles.
Vertical angles are always congruent.
This means that Angle 5 is also 42 degrees.
As we discussed earlier, Angles 1 and 5 are complementary. (Add up to 90 degrees)
42+x=90
Subtract 42 from both sides.
x=48
m<1=48
Answer:
It is 48 degrees because I took the test

How many people have a membership?
Answer:
38 people have a membership.
Step-by-step explanation:
That's because the bottom row shows how many years they've had the membership.
And the y axis shows how many people or the frequency of people having the membership for that amount of years.
So its a bar graph that shows you how many of the members have had the membership for a set amount of years.
So all you have to do is add up each column,
0-2 years = 6 people
2-4 years = 8 people
4-6 years = 10 people
6-8 years = 8 people
8-10 years = 6 people
6 + 8 + 10 + 8 + 6 = 38

Answer:
(x + 3)(x² – 3x + 7)
Step-by-step explanation:
To express x³ + 2x + 21 in the form of (x + 3)(px² + qx + r),
we need to divide (x³ + 2x + 21) by
(x + 3), since (x + 3) is a factor of
(x³ + 2x + 21)
See attached photo on how to divide (x³ + 2x + 21) by (x + 3).
From the attached photo,
(x³ + 2x + 21)/ (x + 3) = x² – 3x + 7
Therefore,
x³ + 2x + 21 => (x + 3)(px² + qx + r)
x³ + 2x + 21 => (x + 3)(x² – 3x + 7)

ASAPPP What is the slope of the line represented by the equation y
3?
-3
4
o
O
The slope of the line represented by this equation is 4/5.
We know this because this line is in slope-intercept form, y=mx+b, where m represents the slope and b represents the y-intercept. Thus, we can conclude that the slope is 4/5, which means that for every 4 units the line moves up, it also moves 5 units over (because slope is defined as rise/run).
This equation is in slope-intercept form, or
y = mx + b where m is the slope and b is the y-intercept. The number in the m position in our equation is 4/5, so the slope is 4/5
Hope this helps!

The capacity of the water tank = 5.04 m³
5,040 litres
For what value of k does the line represented by the equation 1-kx = -3y contain the point (4,-3)?
Answer:
k = -2
Step-by-step explanation:
Given equation
1-kx = -3y
point on this line = (4,-3)
If point lies on the given line, then if we plug in the value (4,-3), then it will satisfy the equation
1-kx = -3y
using x = 4 and y = -3
1-k*4 = -3*-3
1 - 4k = 9
=> -4k = 9 -1 = 8
=> k = 8/-4 = -2
Thus, value of k is -2
