Answer:
The slope of the line is -7/8
When the point (7, –4) is used, the point-slope form of the line is
y+4=(-7/8)(x-7)

Two sides of a triangle are equal in length, and the third side is 5 less than the length of the equal sides. If the perimeter of the triangle is 49, how long are it's sides?
Answer:
let the length of each of the 2 equal sides= n
then n+n+(n-5)=49
3n=44
n=44/3
Answer:
let the length of each of the 2 equal sides= n
then n+n+(n-5)=49
3n=44

Step-by-step explanation:
Step 1: Subtract 3 from both sides of the inequality. Step 2: __________ Step 3: Divide both sides of the inequality by the coefficient of x. What is the missing step in solving the inequality 5 – 8x < 2x + 3? Add 2x to both sides of the inequality. Subtract 8x from both sides of the inequality. Subtract 2x from both sides of the inequality. Add 8x to both sides of the inequality.
Answer:
the answer is d add 8x to both sides
Step-by-step explanation:
The missing step in step 2 is to add 8x to both sides of the inequality.
What is inequality?An inequality shows the relationship between two mathematical expressions which is denoted by the inequality signs such as (<, >, ≤, ≥).
The inequality given is expressed as:
5 - 8x < 2x + 3
Step 1 says to minus 3 from both sides.5 - 8x - 3 < 2x + 3 - 3
2 - 8x < 2x
We are required to determine what to do in step 2.So, we need to add + 8x to both sides, in order to eradicate the variable (8x) from the left-hand side.
i.e.
2 - 8x + 8x < 2x + 8x
2 < 10x
In step 3, we divide both sides by the coefficient of x.
i.e.

u/4 + 12 =18
worth 10 points
Answer:
u = 24
Step-by-step explanation:
[tex]\frac{u}{4}[/tex] + 12 = 18
-12 -12
[tex]4*\frac{u}{4}[/tex] = 6*4
u = 24
Answer:
u = 24
Step-by-step explanation:
Original Equation:
u/4 + 12 = 18
Subtract 12 from both sides
u/4 = 6
To separate the u from the 4, multiply both sides by 4
u = 24

Step-by-step explanation:
Charge of 9 gigs for A
find slope:
125 - 95/5 - 3 = 30/2 = $15/month
use point slope form with point (3,95) and slope 15:
y - y1 = m(x - x1)
y - 95 = 15(x - 3)
y - 95 = 15x - 45
+ 95 +95
y = 15x + 50
put 9 for x, gigs, in the new equation:
y = 15(9) + 50
y = 135 + 50
y = 185
$185 for opt A
Charge of 9 gigs for B
slope = 0
there is the fee of 150 so the equation is:
y = 0x + 150
Next find the price for 9 gigs
y = 9(0) + 150
y = 150
$150 for opt B
Charge of 9 gigs for C
use graph and the cost is about $157
A: $185
B: $150
C: $157

In ΔUVW, w = 79 inches, u = 57 inches and ∠V=73°. Find the length of v, to the nearest inch.
Answer:
83
Step-by-step explanation:
The measure of the side v for the triangle is 82.8 inches.
What is geometry?One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.
Given that in ΔUVW, w = 79 inches, u = 57 inches and ∠V=73°. The measure of the side v is calculated by the formula,
v² = u² + w² - 2uvcosv
v² = ( 57)² + (79)² - 2 x 57 x 79 x cos73
v² = 6856.9
v =√6856.9
v = 82.8 inches
Hence, the value of v will be 82.8 inches.

A skirt originally cost $10. How much will it cost if you sell it in Amazon with 25% mark-up price
Answer:
$20.40
Step-by-step explanation:
20% off means that the new price of the skirt will be 80% of the original price:
$30(100% – 20%) = $30(80%)
Converting the percent to a decimal gives:
$30(0.8) = $24.00
There is an additional 15% off the sale price of $24.00, so the final price is 85% of the sale price:
$24(100% – 15%) = $24(85%)
Again converting the percent to a decimal gives:
$24(0.85) = $20.40
