Find the equation of the line
Answer:
y = 2x - 7
Step-by-step explanation:
The question is asking for slope-intercept form, y = mx + a.
Given:
(1, -5) and (9, 11)
Find the slope (m) between the two points:
m = (y2 - y1) / (x2 - x1)
x1 = 1
x2 = 9
y1 = -5
y2 = 11
m = ( 11 - (-5) )/(9 - 1)
= 16/8
m = 2
y = 2x + a
Use one of the two points to find a (I will use (1, -5)):
-5 = 2(1) + a
-5 = 2 + a
-7 = a
a = -7
y = 2x + (-7)
y = 2x - 7
Joe is traveling from one city to another. He is looking at a map and realizes that 4 cm represents 25 miles.He then used a ruler to measure the distance on the map between two cities that he is traveling. The distance between them is 160 cm. How far, in miles are the two cities apart?
Answer:
The two cities are 1,000 miles apart
Step-by-step explanation:
The key to solving this is in the scale given:
4cm represents 25 miles
4cm = 25 miles
∴ 1 cm = 25 ÷ 4 = 6.25 miles
Measured distance on map = 160cm
1 cm = 6.25 miles
∴ 160 cm = 160 × 6.25 = 1000 miles
∴ The two cities are 1,000 miles apart

Solve for x.
Answer:
x = 17
Step-by-step explanation:
Since 2 sides of the triangle are congruent then it is isosceles, so
The 2 base angles are congruent, both 29°, thus
11x - 65 = 180 - (29 + 29) = 180 - 58 = 122 ( add 65 to both sides )
11x = 187 ( divide both sides by 11 )
x = 17

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
They have $30.00 to spend between them.
let $x be the amount each contributed.
So, the equation to determine how each of them contributed

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
Samantha invested $660 into an account that paid 3.5% interest compounded annually.
