Write the equation of a line with a slope of 5 and a y-intercept of (0, 3). Write the equation in slope-intercept form.
Answer:
y=5x+3
Step-by-step explanation:
Hi there!
We are given that a line has a slope of 5, and a y intercept of (0,3)
We want to write the equation of this line in slope-intercept form
Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept
Since we were given the slope and the y intercept, we can simply substitute these values into the formula to find the equation.
Starting with the slope:
Substitute 5 as m into the equation
y=5x+b
Now for the y intercept:
As stated before, b is the value of y at the y intercept; in this case, b is equal to 3
Substitute 3 as b into the equation.
y=5x+3
Hope this helps!

A safety auditor at a paint factory took a random sample of 25 cans of paint from a production run of over

Based on this sample, which of the following is a 95% confidence interval for the mean amount of lead per can
of paint (in ppm) in this production run?
Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval is (29.6, 44.4).
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 25 - 1 = 24 df, is t = 2.0639.
The other parameters are given by:
[tex]\overline{x} = 37, s = 18, n = 25[/tex].
Hence, the bounds of the interval are given as follows:
[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 37 - 2.0639\frac{18}{5} = 29.6[/tex]
[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 37 + 2.0639\frac{18}{5} = 44.4[/tex]

Sarah is designing a triangular pyramid made of all glass to go on top of a building. All of the faces of the pyramid have a height of 17 feet and a base of 20 feet.
How much glass is needed?
A.
680 sq ft
B.
340 sq ft
C.
2,040 sq ft
D.
1,360 sq ft
Answer:
981.496 ft^3
Step-by-step explanation:
Volume of triangular pyramid is
1/3 base area * height
area of a equilateral triangle base is
sqrt (3)/4 s^2 where s = side length
so the volume is
1/3 ( sqrt(3) / 4 ) (20^2) * 17 ft^3
= 981.496 ft^3
Answer:
Area of a triangle is 1/2 x base x height.
area of triangle = 1/2 x 20 x 17 = 170 square feet.
the image shows 4 triangles, total area = 170 x 4 = 680 square feet.
the answer is A. 680 sq. ft.

Snyder’s Moving company has two segments of customer: Small Business (SB) and Residential. 10% of Snyder’s 2,200 clients fall into both categories, using Snyder’s as their mover of choice for both their business and personal needs. The remaining clients are split evenly between segments. A client who falls into one category will use Snyder’s once every 3 years. Clients who fall into both categories use Snyder’s twice every 3 years. SB moves cost 15% more to the clients than Residential moves due to additional insurance costs for Snyder’s. The average profit Snyder’s makes per move, regardless of which type, is $260. Snyder recently launched a marketing campaign to all SB-only clients to encourage them to use Snyder’s for residential moves. 10% of recipients decided to do so. Assuming the campaign cost $500 to execute, how profitable was it?
$12,480
$25,240
$50,480
$56,240
If the campaign of Snyder’s Moving company costs $500 to execute, it has been computed that the profit will be C. $50,480.
How to calculate the profit?Firstly, the customer base will be:
= 50% × [2200 - (10% × 2200)]
= 50% × (2200 - 220)
= 990
The increase in customers will be:
= 10% × 990
= 99
The additional profit will be:
= [(99 × $260) - $500] × 2
= ($25740 - $500) × 2
= $50480

10% SB clients will move due to the promotion. The Profit will be $25,240
Step-by-step explanation:
Find the number of clients in both SB and personal:
10% x 2200 = 220
Find the number of SB clients:
(2200 - 220)/2 = 990 ( the rest of clients will be evenly splitted)
Find the number of SB clients who will move:
10% x 990 = 99
Find the profit due to the move: (Number of ppl moved x Average Profit - Initial Investment)
99 x $260 - $500 = $25,240

John is replacing two strings of his guitar and he has two pieces of information about them.
One string is 3 inches longer than the other string.
The product of the strings' length is 108 inches.
Write the equation to find the length of the shorter string, x?
Answer:
x(x +3) = 108
Step-by-step explanation:
The longer string is 3 inches longer than the shorter string, whose length is x. Then the longer string is (x+3), and the product of their lengths is ...
x(x +3) = 108 . . . . . equation for finding the shorter length
__
In standard form, the equation is ...
x² +3x -108 = 0
(x -9)(x +12) = 0 . . . . . factored form
The values of x that make these factors zero are 9 and -12. The shorter string length is 9 inches.
_____
Additional comments
John's guitar is unusually small if its strings are 12 inches or less.
Note that factoring is accomplished by finding factors of 108 that differ by 3. This requires the same thinking process as solving the problem directly without the use of an equation. We know the product of two numbers is 108 and one is 3 larger than the other.
The difference (3) is sufficiently smaller than the product that the square root of the product (10.4) will be about halfway between the numbers. We can reasonably guess their values to be 10.5±3/2 = {9, 12}. (There is a more formal way to make this calculation by defining a variable (a) to be the average of the two lengths: Then you have (a-3/2)(a+3/2)=108, or a² = 110.25 and a=10.5. This matches our approximation.)

Hope it helps
A straight angle is an angle equal to 180 degrees
Solve for y
y + 51° + 56° = 180°
y = 180° - 56° - 51°
y = 73°
Total interior angle of a triangle sum ups to 180°
Solve for x
y + x + 72° = 180°
73° + x+ 72° = 180°
x = 180° - 72° - 73°
x = 35°

4th: y = 29
Answer:
1. y = -30
2. x = -1
3. x = 5
4. y = 29
Step-by-step explanation:
1. y = -10x
f(x) = 3
y = -10*3
y = -30
2. y = -2x + 1
f(y) = 3
3 = -2x + 1
-2x = 3 - 1
-2x = 2
x = 2\-2
x = -1
3. y = 6x
f(y) = 30
30 = 6x
x = 30\6
x = 5
4. y = 5x + 9
f(x) = 4
y = 5*4 + 9
y = 20 + 9
y = 29

What value of x makes this equation true? 12x - 15 =6 - 3x A. 7/3 B. 3/7 C. 5/7 D. 7/5
Answer:
7/5
Step-by-step explanation:
12x - 15 =6 - 3x
Add 3x to each side
12x+3x - 15 =6 - 3x+3x
15x -15 = 6
Add 15 to each side
15x -15+15 = 6+15
Divide by 15
15x/15 =21/15
x = 7/5
Answer:
[tex]\boxed{x = \dfrac{7}{5}}[/tex]
Step-by-step explanation:
Given equation:
[tex]12x - 15 = 6 - 3x[/tex]
To solve for x, we need to isolate the "x" variable on one side of the equation. The constant obtained on the other side of the equation will be the solution (x).
Add 15 both sides of the equation:
[tex]\implies 12x - 15 + 15 = 6 - 3x + 15[/tex]
[tex]\implies 12x = 21 - 3x[/tex]
Add 3x both sides of the equation:
[tex]\implies 12x + 3x= 21 - 3x + 3x[/tex]
[tex]\implies 15x= 21[/tex]
Divide both sides by 15 to isolate the cooeficient from "x".
[tex]\implies \dfrac{ 15x}{15} = \dfrac{21}{15}[/tex]
[tex]\implies x = \dfrac{21}{15}[/tex]
Simplify the value of "x" as required:
[tex]\implies x = \dfrac{7 \times 3}{5 \times 3}[/tex]
[tex]\implies \boxed{x = \dfrac{7}{5}}[/tex]
