Answer:
The answer is y = -3x + 7.
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟
[tex]y = mx + b[/tex]
❃Incase you also forgot, what the slope formula is ☟
[tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
➊ First: We are going to be solving for the slope.
[tex]m = \frac{ - 8 - 1}{5 - 2} = \frac{ - 9}{ \: \: \: 3} = - 3[/tex]
➋Second: We find the y-intercept.
[tex]y = mx + b \\ 1 = - 3(2) + b \\ 1 = - 6 + b \\ \frac{ + 6 = + 6 \: \: \: \: \: \: \: \: \: }{7 = b}[/tex]
➌Third: Plug in.
[tex]y = - 3x + 7[/tex]

Write an inequality to represent "7 less than one sixth of a number is at most 45."
Answer:
third option
Step-by-step explanation:
one-sixth of a number = 1/6 ·n
one-sixth of a number, decreased by 7 = (1/6 ·n) - 7
'at most 45' means values equal to 45 or less: ≤
nine less than the product of two and a number p
Answer:
(2 · p) - 9
Step-by-step explanation:
p is unkown.
Expression: (2 · p) - 9
Find p in order to solve the expression.
Greg buys apples, bananas, and kiwis from a fruit stand each week. The first week he pays $3.19 for 2 apples, 3 bananas, and 2 kiwis. The second week he pays $4.12 for 3 apples, 4 bananas, and 2 kiwis. The third week he pays $3.01 for 1 apple, 1 banana, and 4 kiwis. Choose the system of equations that can be used to solve for the number of apples,a, the number of bananas,b, and the number of kiwis,k.
Answer:
Step-by-step explanation:
2a+3b+2k= $3.19
3a+4b+2k=$4.12
1a+1b+4k=$3.01
The system of equation that can be used to solve these scenario are 2a + 3b + 2k = 3.19, 0a + 4b + 2k = 4.12 and 1a + 1b + 4k = 3.01.
What is a linear equation?A linear equation consist of variables and constant sperated by arithmetic operations which has highest degree of 1.
We know that a system of equations is formed when we have two or more than two linear equations in two or more than two variables and a system of equations is consistent when the number of variables is equal to or less than the number of equations.
Given in this questin is 3 variables Applles(a). Bananas(b) and Kiwis(k) and we can form three equations in three variables they are,
2a + 3b + 2k = 3.19...(i)
0a + 4b + 2k = 4.12...(ii)
1a + 1b + 4k = 3.01...(iii)
We can solve this system of equation by first multiplying eqn(iii) by 2 and then subtracting it from eqn(i) to eliminate variable 'a' and then equating with eqn(ii) to eliminate variable 'b' or 'k'

What is the measure of
A. 60°
B. 80°
C. 110°
D. 120°
Answer:
A. 60 degrees
Step-by-step explanation:
The sum of the abgles in a triangle is 180°. We are already given 96° and 24°.
so we will subtract the given values from 180 to find the third angle
180-(96+24)=180-120=60°
The answer is A. 60°

Find the measure of the arc. Please help!
Answer:
The value of mEFD = 214°
Step-by-step explanation:
Given that the measure of the degree of one of the central angles of an inner circle is 146°.
We know that sum of all central angles is 360°.
In other words, in our case
mEFD + 146° = 360°
Thus, we can determine the mEFD using the equation
mEFD + 146° = 360°
so subtracting 146° to both sides
mEFD + 146° - 146° = 360° - 146°
mEFD = 214°
Therefore, the value of mEFD = 214°

The fee for a service call from a plumber can be modeled with the function C(h)= 75 + 20h, where C is the total cost of the service call and h is the number of hours the plumber spends working on the problem. (MAFS.912.F-IF.1.2) A. How much does the plumber charge per hour? 3. What is the value of C(3)? 1. What does this represent in terms of the problem?
Answer:
20 ; $135 ; service charge for 3 hours spent is $135
Step-by-step explanation:
Given that :
Service fee equation model :
C(h)= 75 + 20h
C = total cost of the service call
h = number of hours the plumber spends working on the problem
The charge per hour is the gradient or slope of the linear equation. From the equation, the slope is of the equation is related to bx from. The general form of a linear equation where b = gradient or slope(charge per hour) and x = number of hours
bx = 20h
b = 20
Charge per hour = 20
C(3) = 75 + 20(3)
75 + 60 = 135
This means that total service call charge for a plumber who spends three hours fixing a problem is $135

Line 1: (-9,3), (-5,7)
Line 2: (-11, 6), (-7, 2)
The slope of line 1 is
The slope of line 2 is
The two lines are
Answer:
The slope of line 1 is: (7-3) / (-5 - -9) = 4/4 = 1
The slope of line 2 is: (2-6) / (-7 - -11) = -4/4 = -1
Yes, they are perpendicular
Step-by-step explanation:
The slope of line 1 is: (7-3) / (-5 - -9) = 4/4 = 1
The slope of line 2 is: (2-6) / (-7 - -11) = -4/4 = -1
slope 2 = - 1/1 = - 1/slope 1

Sam is 12 years older than Matt. Five years ago the
sum of their ages was 28. How old are they now?
Write a system of equations to represent this situation.
Define your variables
Answer: y=x+12
(y-5) + (x+5)=28, where x = present age of Matt ( in years).
and y= present age of Sam.
Step-by-step explanation:
Let x be the present age of Matt ( in years).
and Sam's present age = y years
5 years's ago,
Sam's age = y-5 years
Matt's age = x-5 years
As per given,
y=x+12 (i)
and (y-5) + (x+5)=28 ....(ii)
Required system of equations:
y=x+12
(y-5) + (x+5)=28, where x = present age of Matt ( in years).
and y= present age of Sam.
Ulani is constructing a triangle that has sides measuring 12 cm and 28 cm. Which measurements could be the length of the third side? Select two options
Answer:
The sides can be 38 and 24.
Step-by-step explanation:
Consider the provided information.
The given options are: a) 15, b) 24, c)38, d)41, E)53
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
Here a=12 and b=28 we need to find c
The sum of 12 and 28 is 40.
So, It means the side can not be 41 and 53 as it is greater than 40.
Now let the third side is 15.
Then the sides are 12, 28 and 15
The sum of two smaller sides: 12+15=27
But 27 is less than 28.
So the side can't be 15.
Now let the third side is 24.
Then the sides are 12, 28 and 24
The sum of two smaller sides: 12+24=36
But 36 is greater than 28.
So the side can be 24.
Now let the third side is 38.
Then the sides are 12, 28 and 38
The sum of two smaller sides: 12+28=40
But 40 is greater than 38.
So the side can be 38.
Hence, the sides can be 38 and 24.
A clothing store is raising the price of all its sweaters by $3.00. What is an expression that could be used to find the new price of a sweater that originally cost d dollars? *
Answer:
x+3
Step-by-step explanation:
Answer:
Step-by-step explanation:
The expression would be d + 3.
You're raising $3 in every sweaters cost so d is the cost of the sweater and you add 3 to raise $3 in the price.
The first term is 8 Each term is 4 more than double the previous term.
Answer:
8*2^(n-1)
Step-by-step explanation:
This is a geometric sequence since we multiply from the previous term.
a_n = a_1 * common ratio^(n-1) where a_n is the nth number and a_1 is the first.
The first term is 8, so we have
a_n = 8*<common ratio>^(n-1) = 8*2^(n-1)

45 and a third divided by one sixth and then write a sentence to show work and create multiplication of number
Answer:
272
Step-by-step explanation:
45 and a third = 45 1/3
one sixth = 1/6
hence:
45 and a third divided by one sixth =
= 45 1/3 ÷ 1/6
= 136/3 ÷ 1/6
We convert to multiplication by converting 1/6 to its reciprocal which is 6/1
Hence:
= 136/3 ×6/1
= 272
