Answer:
y-30 = 3(x-1)
Step-by-step explanation:
Point-slope form of an equation is
y-y1 = m(x-x1) where (x1,y1 ) is a point and m is the slope
We know on day 1 they exercised 30 minutes (1,30) where x is the number of days and y is the minutes. The rate increased 3 minutes each day so m = 3
y-30 = 3(x-1)

Suppose that 13 inches of wire costs 39 cents. At the same rate, how many inches of wire can be bought for 21 cents?
Answer:
63 cents
Step-by-step explanation:
Suppose that 13 inches of wire costs 39 cents. At the same rate, how many inches of wire can be bought for 21 cents?
0.39/13 = 0.03in
o.03 X 21 = 0.63
so 63 cents check
63/21 should equal 39/13
63/21 = 39/13
63 X 13 = 39 X21
21 X 3 X 13 = 3 X 13 X 21
yes
21 X 3 X 13 = 21 X 3 X 13
The measure of the supplement of an angle is 60° less than four times the measure of the complement of the angle. Find the measure of the angle.
Answer:
140° and 50°
Step-by-step explanation:
The supplement of the angle (180 - x)
The complement of the angle = (90 - x)
(180 -x) = 4(90-x) - 60
180 - x = 360 -4x - 60
180 -x = 300 - 4x
180 - x + 4x = 300
180 + 3x = 300
3x = 120
x = 40
The supplement (180 - x) = 180 - 40 = 140°
The complement (90 - x) = 90 - 40 = 50°

Answer:
Destroy the end crystals (using a bow for far range). If it spreads a poisonous gas, dig a hole and retreat there for a few seconds. Once you destroy all the crystals (since it’s it healing source), start attacking it with your sword once the dragon swoops down on the portal (it depends on the enchantments & the sword itself). Keep repeating that until the dragon is killed.

87.46
The value of the given expression is 87.46.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given expression will be solved as below:-
E = 84-( -√12)
Two negative signs cancel out into a positive sign
E =84 + √12
84 plus the square root of 12. The square root of 12 is 3.5 or 3.46.
E = 84 + 3.46
E = 87.46
Therefore, the value of the given expression is 87.46.

Answer:
<1 = 12.71 degrees
<2 = 77.29 degrees
Step-by-step explanation:

7x = 90 - 1
x = 89/7
x = 12.71
the sum of three times a number and eleven is greater than or equal to fifty
Answer:
3n + 11 ≥ 50
Step-by-step explanation:
The word "sum" refers to addition as it is the term for the answer to an addition problem, so you know that there should be an addition sign in this inequality.
The word "times" means to multiply!
So you are multiplying 3 by some number which we will call it n. Now it says the SUM of 3n and eleven...meaning you are adding 3n and 11.
Greater than or equal to is a way of saying this symbol "≥" And "fifty" in numbers is 50
Your answer should be 3n + 11 ≥ 50
Hope this helps :)

On the second day, she sells 8 adult tickets and 11 child tickets for a total of $97.00. Which system of linear equations can be used to determine the cost of each adult ticket (x) and each child ticket (y)?
A) 5x + 6y = 58 8x + 11y = 97
B) x + y = 155 x + y = 30 Eliminate
C) 5x − 6y = 58 8x − 11y = 97

On the planet Pisquet, there are 4 kents to every 15 hopts. If farmer Umpt has 120 hopts on her naxvip farm, how many kents are on the farm?
You will get a brain list if the answer is right.
Answer:
15
Step-by-step explanation:
We know according to the figure that 9^2+12^2 = z^2,
as a result, we know that z^2 = 225
and z = 15
Another method is to recognize that this figure is similar to a 3-4-5 triangle. According to the converse of the Hypotenuse-Leg theorem, we get that the third length of the triangle is 15
A clothing
store offers a rewards program in which customers earn points by making purchases at the
store. Every item bought is worth 8 points, and customers earn 20 points when they sign up. Write an
equation for the function that gives the number of points based on the number of items bought. How
many points will a customer have after making 16 purchases?
Answer:
Equation for the function: y=8x+20
Step-by-step explanation:
8 represents points per item/rate of change
20 represents the y intercept or what the person gains in the beginning that doesn't change.
8(16)+20
128+20
=148
After making 16 purchases the person will have 148 points.
14. This year, a rancher counted 225 horses on
the range. This count is 22 fewer than last
year. How many horses did the rancher count
last year? Let h be the number of horses
counted last year. Solve h-22 = 225 to find
the number of horses counted last year.
Answer:
247 horses
Explanation:
Key Info: 225 horses this year and this is 22 horses fewer than last year
We know that fewer means it is subtraction, but since we don't know how many horses were there last year we do the opposite which is addition.
In this case the inverse or opposite equation is 225 + 22 = h.
After adding this up you should get 247 horses were there last year.
There are 247 horse counts last year.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
A rancher counted 225 horses on the range, which is 22 fewer than last
year.
let h be number of horses counted last year.
Then, the number of horses count
h - 22 = 225
add 22 on both side
h -22 + 22= 225 + 22
h = 247
Hence, there are 247 horse counts last year.

Write the equation of a quadratic function that has been shifted 3 units down, to the right 2 units, and
stretched vertically by a factor of 5.
Answer:
y = 5(x² - 2) - 3
Step-by-step explanation:
In y = a(x² - b) + c, a is the stretch factor, -b is the horizontal, and c is the vertical
You did not give us the parent function, so I am going to assume it is y = x²
y = x²
3 units down means the function will be moved 3 units down, so it will look like:
y = (x²) - 3
Shifted 2 units to the right will result in a -2, so we add that in:
y = (x² - 2) - 3
The stretch factor is 5, which goes in front of everything else, multiplying the quadratic,
y = 5(x² - 2) - 3
