Find the equation of a line which has:
slope of -2 and
crosses the y-axis at 5
in slope-intercept form
Answer:
y = -2x + 5
Step-by-step explanation:
Recall that slope-intercept form is y = mx + b where m is the slope and b is the y intercept
In this case our slope is m = -2
and, line crosses y-axis at 5 which is b = 5
thus, y = -2x + 5
Hi! Short math question

Answer:
The independent variable is the number of cars
the band washes and the dependent is the number of money they earn
Step-by-step explanation:
are 4/5 and 1/2 equivalent explain
Answer:
They are not
Step-by-step explanation:
4/5 cannot be simplified, plus 1/2 indicates half of a fraction but 4/5 is not half if a fraction, therefore they are not equivalent.
Find the perimeter of the rectangle. 11. 13 cm Area = 52 cm2
Answer:
1352 cm
Step-by-step explanation:
Length (l) = 13 cm
Width (w) = 52 cm
Perimeter of the rectangle = 2(l + w) units
P = 2(13 + 8)
P = 2 (21)
P = 42
Thus, the perimeter of the rectangle is 42 cm.
Example 2: If a rectangle's length is 2x + 1 and its width is 2x – 1. If its area is 15 cm2, what are the rectangle's dimensions and what is its perimeter?
Solution:
We know that the dimensions of the rectangle in terms of x:
l = 2x + 1
w = 2x – 1
Since the area of a rectangle is given by:
A = l * w
We can substitute the expressions for length and width into the equation for area in order to determine the value of x.
A = l * w
15 = (2x + 1) (2x -1)
15 = 4x2 – 1
16 = 4x2
x = ±2
Note that the value of x must be positive and therefore in our case, the value of x is 2. And now we have:
l = 11 cm
w = 52 cm
Therefore, the dimensions are 5cm and 3cm.
Now, substituting these values in the formula for perimeter, we will get
P = 2l + 2w
P = 2(5)+2(3)
P = 10+6
P = 16 cm
Find an equation in point slope form for the line haveing the slope m=-3 and containing the point (6 7)
Answer:
7-y=-3(6-x)
Step-by-step explanation:
Point slope form:
[tex]y-y_{1} = m(x-x_{1} )[/tex]Substitute y in for 7. Substitute x in for 6. Substitute m in for -3.
7-y=-3(6-x)Pls dont give just the answer, (you dont need to explain how to do it)

10. If log10x = 1 + a and log10y = 1 – a, show that xy = 100.
How?
Step-by-step explanation:
log x = 1 + a
a = log x - 1
log y = 1 - a
a = 1 - log y
So
log x - 1 = 1 - log y
log x + log y = 2
log (xy) = 2
xy = 100

Step-by-step explanation:
please help me in this question
question is given below:
(a) List all the possible outcomes
A dice has 6 sides, ranging from numbers 1 to 6.
As such, the possible outcome for 1 dice is 1, 2, 3, 4, 5 and 6.
Since 2 dice are used, the possible outcome increases, ranging from 2 to 12.
Working:
1 + 1 = 2 (MIN)
6 + 6 = 12 (MAX)
Therefore, the possible outcomes is from 2 to 12.
(b) Find the probability of getting an even number as a score
Total number of score = 11
Total number of even score = 6
P (even number) = 6 / 11

A middle school took all of its 6th grade students on a field trip to see a ballet. The students filled 1898 seats, which was 73% of the total number of seats in the theater. How many total seats were in the theater?
Answer:
x = 2600 seats.
Step-by-step explanation:
Let the total number of seats be x.
Given the following data;
Number of seats occupied = 1898 seats
Percentage = 73%
To find the total number of seats;
Translating the word problem into an algebraic equation, we have;
[tex] \frac {73}{100} * x = 1898 [/tex]
Cross-multiplying, we have;
[tex] 73x = 1898 * 100 [/tex]
[tex] 73x = 189800 [/tex]
[tex] x = \frac {189800}{73} [/tex]
x = 2600 seats.
Therefore, the total number of seats in the theater are 2600 seats.

Following order of operations:
3^2 = 9
(10-2) = 8
Now you have :
9 + 8 x 5 -4
Multiplication is next:
9 + 40 -4
Now just add and subtract from left to right:
9 + 40 = 49
49-4 = 45
The answer is 45
Step-by-step explanation:
So first you solve whats inside of the parenthesis 10 -2 aand get 8 then you figure 3^2 which is 9 then multiplie 8 times 5 and get 40. 9 + 40 - 4 is what it is so far then add 9 to 40 which is 49 then subtract 4 and get 45!

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 4(m∠Y) − 160°. Find m∠Y
Answer:
I think the answer is 50.
Step-by-step explanation:
Y + S = 90
S = 4 (Y) - 160
160 = 4 (Y)
Y = 40
90 - 40 = 50

3/8 + 1/4 = Tap on the pic to see wiestion
Answer:
3/8 + 1/4 is 5/8 and 1/10+4/5 is 1
Step-by-step explanation:
convert 1/4 to 2/8 and add to 3/8 to get 5/8
convert 4/5 to 9/10 and add to 1/10 equals 10/10 which is also 1
Answer:
9/10 (and 5/8 for question in title)
Step-by-step explanation:
To add fractions, you need to make a common denominator, which you can have a common denominator of 10.
To do this, multiply the numerator (4) and the denominator (5) by 2. You will get 8/10.
Now you can add them together: 8/10 + 1/10 = 9/10
I don't know if you wanted the question in the title answered too so here:
Same thing; common denominator. Use 8. Multiply 1 by 2 and 4 by 2. You get 2/8.
Add: 3/8 + 2/8 = 5/8

Write an equation of the line that passes through the points (−6,20) and (0, 8).
Answer:
y = -2x + 8
Step-by-step explanation:
(−6, 20) and (0, 8)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(8 - 20) / (0 - (-6))
Simplify the parentheses.
= (-12) / (6)
Simplify the fraction.
-12/6
= -2
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -2x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (0, 8). Plug in the x and y values into the x and y of the standard equation.
8 = -2(0) + b
To find b, multiply the slope and the input of x(0)
8 = 0 + b
b = 8
Plug this into your standard equation.
y = -2x + 8
This is your equation.
Check this by plugging in the other point you have not checked yet (-6, 20).
y = -2x + 8
20 = -2(-6) + 8
20 = 12 + 8
20 = 20
Your equation is correct.
Hope this helps!

Is $20.29 with $4 dollar shipping more, or is $23.09 with 3 dollar shipping more? Help please, ASAP! :(
Answer:
23.09 w/ 3 dollar shipping is more.
Step-by-step explanation:
20.29 + 4 = 24.29
23.09 + 3 = 26.09
hope this helps :)
Answer:
23.09 dollars and 3 dollar shipping is more than 20.29 with 4 dollar shipping
Step-by-step explanation:
if you add the shipping and price together 23.09 dollars and 3 dollar shipping is 26.09 in total
And the 20.29 with 4 dollar shipping is 24.29 in total
and 26.09 is greater than 24.29, so 23.09 dollars and 3 dollar shipping is more than 20.29 with 4 dollar shipping
