y = 5x - 6&y= -4x + 3
Use the Equal Values Method to solve for x and y
Answer: x = 1 and y = -1
Step-by-step explanation:
Since both equations are equal to y, that means the equations are both equal to each other
5x - 6 = -4x + 3
Solve for x how you would traditionally do it with any other one-variable equation
9x = 9
x = 1
Plug the now known x value into either equation and you will get your y value.
5(1) - 6 = -1
-4(1) + 3 = -1

in the diagram the measure of angle one is 3X the measure of angle two is 12 X what is the measure of angle 4
Answer:
144°
Step-by-step explanation:
m<1 =3x
m< 2= 12x
1&2 are supplementary angles, so
3x+12x= 180
15x=180
x= 12°
measure of angle 4 equals the measure of angle 2
because they're head opposite angles
m<4= 144°

In 8 hours if Martha writes 2 essays, how many essays can she write in 15 hours?
Answer:
Martha can write 3.75 essays in 15 hours. (Which is a lot for me)
Step-by-step explanation:
First, I divide 2 by 8.
2 ÷ 8 = 0.25
Next I multiply 0.25 by 15.
0.25 * 15 = 3.75
So, the answer is 3.75
Hope this helps! :)
Step-by-step explanation:
in 8 hours she wrote = 2 essay
in 1 hour she wrote = 2/8 = 1/4
in 15 she wrote = 15 × 1/4 = 15/4 or 3.75 essays .

formulas A=bh/2 A=bh and I have 6in 4in 6in 10in and I have to find the area
Answer:
Lots of "ifs" here.
A=bh/2 is the formula for the area of a triangle.
A=bh is the formula for the area of a rectangle or a parallelogram.
If the 6 & 4 area the base & height of a rectangle, then (6)(4) = 24 in^2
If the 6 & 10 are the base and height of a triangle, then 1/2(6)(10) = 30 in^2

Isabel’s class has collected 90 cans in a food drive. They plan to sort the cans into n bags, with an equal number of cans in each bag. Write an expression to show how many cans there will be in each bag.
Answer:
90/n
Step-by-step explanation:
There are 90 cans, and each bag MUST have an equal amount of cans, so if we had, let's say 2 bags, then there would be 45 bags. We got this by doing 90/2. 2 being n, the expression would be 90/n.
Y=2x
Y=7x-20
I’ll give you brainlessly
Answer:
(4,8)
Step-by-step explanation:
y = 2x
y = 7x-20
Step 1: plug in 2x for y
Step 2: subtract 7x on both sides
Step 3: divide by -5 on both sides
Step 4: plug in 4 into y = 2x
2x = 7x -20
-7x -7x
-5x = -20
-5 -5
x = 4
y = 2(4)
y = 8
Which answer describes the sequence {1,3,7,15,…} as a mathematical statement?
Answer:
so just successive powers of 2
Step-by-step explanation:
1, 3, 7, 15, 31, 63, _? Add successive powers of 2 to the number: 1+2=3; 3+4=7; 7+8=15; 15+16=31; 31+32=63; 63+64=127.
The given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.
Given that,
To justify the given sequences 1,3,7,15.
Arithmetic progression is the series of numbers that have common differences between adjacent values
What is geometric progression?Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
Here,
Given a sequence, 1,3,7,15
where first term A0 = 1
second term A1 = 1 + 2 = 3
third term A2 = 3 + 4 = 7
From above sequence we can conclude the general term for the sequence as, S = A(n-1) + (A(n-1) + 1)
Thus, the given sequence {1,3,7,15,…} has general term S = A(n-1) + (A(n-1) + 1) where A0 = 1.

Define cach variables with a "Let" statement, write two equations, and solve completely.
Answer:
Step-by-step explanation:
Let x equal number of weeks and y equal money in the bank.
Nancy, y=425+25x
Sam, y=705-15x
The system of equations:
Nancy: [tex]y=\$425+\$25x[/tex]

Amount spend by Sam each week = $15
To find:
The system of equations describing the given models.
Solution
1) Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Let the number of weeks Nancy saving her money be 'x'.
Let the total amount of money in Nancy's bank after x weeks be 'y'.
[tex]y=\$425+\$25\times x\\y=\$425+\$25x[/tex]

The total cost of making a daily taco special for a restaurant is represented by the function C (t) = 2.5t + 1 , where t is the number of tacos made. How does the total cost change for every taco special the food truck makes?
A. The total cost increases by $1.
B. The total cost increases by $2.50.
C. The total cost decreases by $1.
D. The total cost decreases by $2.50.
Answer:
C. The total cost increases by $2.50
Step-by-step explanation:
This is because 1 dollar is constent--- you will always have 1 dollar.
However 2.5 is the change, you have to times a number to get the answer.
EX:
(t) = 2.5t + 1
(4) = 2.5( 4) + 1 ----- plug in 4 for t
= 10 +1
= 11

What is the sign of f on the interval?
The function f(x) will be sometimes positive and sometimes negative on the interval
Option (3) is correct.
What is a function?An arrangement known as a function connects inputs to essentially one output.
In other words, a function is a relationship between variables, and the nature of that relationship—for example, y = sinx and y = x +6—defines the function.
Given function:
f(x) = (x - 5) (2x - 7) (7x - 3)
The term (x - 5) will be negative if x < 5.
The term (2x - 7) will be negative if x<3.5
So, If x = 4, (x - 5) will be negative but (2x - 7) will be positive, resulting in a negative overall value.
Therefore, if x = 3, then (x - 5) will be negative, as well as (2x - 7), making the whole value negative.
Hence, the function f is sometimes positive and sometimes negative on the interval.

y = 9x + 4
Answer:
(-1, -5)
Step-by-step explanation:
[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]
1. We must calculate x, for that we must substitute y, so we have:
5x=9x+4
2. Now we solve the equation.
5x-9x=4
-4x=4
x=-1
3. Now we must calculate y
y=5x
y=5(-1)
y=-5
