Use y = mx + b to determine the equation of a line with a slope -5, passing through the point (-2,4).
Answer:
[tex]y=-5x-6[/tex]
Step-by-step explanation:
Hi there!
In [tex]y=mx+b[/tex], m is the slope of the line and b is the y-intercept (the value of y when x is 0). y and x remain the same but m and b are replaced with numbers.
Given that the slope is -5, plug it into [tex]y=mx+b[/tex]:
[tex]y=-5x+b[/tex]
Now, to solve for b, plug in the given point (-2,4):
[tex]4=-5(-2)+b\\4=10+b[/tex]
Subtract 10 from both sides to isolate b:
[tex]4-10=10+b-10\\-6=b[/tex]
Therefore, the y-intercept of this line is -6. Plug this back into [tex]y=-5x+b[/tex] as b:
[tex]y=-5x-6[/tex]
I hope this helps!

x + 4y = 24
ASAP!!!!
Answer:
y = -1/4x + 6
Step-by-step explanation:
Answer:
y = -1/4x + 6
Step-by-step explanation:
Get y alone:
x + 4y = 24
-x = -x
4y = -x + 24
Divide:
4y = -x + 24
4 = 4
Distribute division:
y = -1/4x + 24/4
Reduce fractions:
y = -1/4x + 6

Alexander is building a rectangular pen in his backyard for his dog. The pen will have a length of 13 feet and a width of 2x feet.
4x+26
Step-by-step explanation:
to buy fencing, you need to find the perimeter of the pen. The perimeter is found by adding all sides together.
So, 13+13+2x+2x=4x+26
#1 Which rectangular prism will have more volume (left or right) or will they be the same?
#2 What are their volumes?
Answer:
They will have the same volume
Step-by-step explanation:
Given the rectangular prisms above :
Prism 1 dimension = (3 * 1 1/2 * 2 1/2) inches
Prism 2 dimension = (2 1/2 * 3 * 1 1/2) inches
Recall; Volume of a rectangular prism is :
V = length * width * height
Prism 1 :
V = (3 * 1 1/2 * 2 1/2) = 11.25 in³
Prism 2 :
V = (2 1/2 * 3 * 1 1/2) = 11.25 in³
Hence, Volume of prism will be the same

What is the length of side x? If necessary, round your answer to two decimal places. 19 12
Answer:
D. 14.73
Step-by-step explanation:
According to Pythagoras,
19^2 = 12^2 + x^2
x^2 = 19^2 - 12^2
x^2 = 361 - 144
x^2 = 217
x = [tex]\sqrt{217}[/tex]
x = 14.73
Consider the equation:
6x+55=x^2
1) Rewrite the equation by completing the square.
Your equation should look like (x+c)^2=d(x+c)
2
=dleft parenthesis, x, plus, c, right parenthesis, squared, equals, d or (x-c)^2=d(x−c)
2
=dleft parenthesis, x, minus, c, right parenthesis, squared, equals, d.
2) What are the solutions to the equation?
Step-by-step explanation:
1.
Subtract the coefficient from both sides, keep 55 on the same side.
[tex] {x}^{2} - 6x = 55[/tex]
Complete the square by dividing the coefficient by two and squaring it.
[tex] {x}^{2} - 6x + 9 = 55 + 9[/tex]
Use binomial to factor the left side.
[tex](x - 3) {}^{2} = 64[/tex]
2. Solve for x.
[tex](x - 3) = 8[/tex]
[tex]x = 11[/tex]
Remeber the square root of 64 is also -8 so
[tex]x - 3 = - 8[/tex]
[tex]x = - 5[/tex]
So the solutions are -5 and 11
Answer:
Answers
1) We can rewrite the equation as 64=(x−3)^2
2) The solutions to the equation are x=3±8
Use the drawing tools to form the correct answer on the graph.
Graph the line that represents this equation:
3x-4y=8
Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]3x - 4y = 8[/tex]
Required
Graph the line
First, we calculate the intercepts
Set x = 0
So:
[tex]3x - 4y = 8[/tex]
[tex]3*0 - 4y = 8[/tex]
[tex]- 4y = 8[/tex]
Divide by -4
[tex]y = -2[/tex]
So, we have:
[tex](x,y) = (0,-2)[/tex]
Next, set y = 0
So:
[tex]3x - 4y = 8[/tex]
[tex]3x - 4 * 0 = 8[/tex]
[tex]3x = 8[/tex]
Divide by 3
[tex]x = 8/3[/tex]
So, we have:
[tex](x,y) = (8/3,0)[/tex]
The graph to be plotted must pass through [tex](x,y) = (0,-2)[/tex] and [tex](x,y) = (8/3,0)[/tex]
Here's my answer

Answer:
agree
Step-by-step explanation:
Answer:
Agree
Step-by-step explanation:
If you multiply 0.2 by 3, you get 0.6
If you multiply 0.6 by 3, you get 1.8
If you multiply 1.8 by 3, you get 5.4
If you multiply 5.4 by 3, you get 16.2
If you multiply 16.2 by 3, you get 48.6
48.6 is close to being half of the island.
Find the zeros of the quadratic function: y= 6(7x + 9)(8x - 3).
A) (-9/7,0), (3/8,0)
B)(-7/9,0), (8/3,0)
C) (-3/8,0), (°/7,0)
D) (-8/3,0), (7/9,0)
Answer:
A) (-9/7,0), (3/8,0)
Step-by-step explanation:
Zeros of a quadratic function:
x for which y = 0.
In this question:
[tex]y = 6(7x + 9)(8x - 3)[/tex]
It's 0 if one of the factors is 0. 6 is never 0, now about the other to:
[tex]7x + 9 = 0[/tex]
[tex]7x = -9[/tex]
[tex]x = -\frac{9}{7}[/tex]
So (-9/7, 0) is a zero of the quadratic function.
The other is:
[tex]8x - 3 = 0[/tex]
[tex]8x = 3[/tex]
[tex]x = \frac{3}{8}[/tex]
(3/8,0) is the other zero.
Thus, the correct answer is given by option A.
