Y=2x
Y=7x-20
I’ll give you brainlessly
Answers
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
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
Answers
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°
Et of y=x2-4 and + y + 2 = 0?
Answers
The equation y = x2 – 4 + y + 2 = 0 can be solved by completing the square.
What is equation?An equation is a mathematical statement that to express our equal. Is consist of two expression separated by an equal sign and can contain numbers, variables and operators. Equation get be used to solve problems make prediction and describe relationship between different quantities. Equation can be can also be used to represent physical laws and other phenomena.
First, subtract y from both sides of the equation to get x2 - 4 + 2 = y. Then, subtract 2 from both sides of the equation to get x2 - 6 = y. Finally, add 9/4 to both sides of the equation to get (x - 3/2)2 = 9/4 + y.
This equation can be solved by taking the square root of both sides to get x - 3/2 = ±√(9/4 + y). Finally, add 3/2 to both sides of the equation to get x = 3/2 ±√(9/4 + y).

23. Describe the slopes of perpendicular lines
Answers
Answer:
The slopes of two perpendicular lines are negative reciprocals of each other. This means that if a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m. For example, we found that the slope of the line y = (1/2)x + 3 is 1/2.
The slopes of perpendicular lines when multiplied together gives the product as -1.
What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.
The negative slope indicates the rate of decrease while the positive shows the rate of increase.
Suppose the two perpendicular lines have equations as follows,
y = m₁x + c₁ and y = m₂x + c₂.
Suppose m₁ = tan θ
Then, m₂ = tan (90° + θ)
Apply the trigonometric identity to obtain,
m₂ = tan (90° + θ) = -cot θ
Now, m₁ × m₂ = tan θ × -cot θ = -1
Thus, the products of slopes is -1.
Hence, the product of slopes of two perpendicular lines is -1.

Diana bought a total of 22 items including boxes of pizza and sodas for an upcoming event. Each box of pizza cost $8 and each soda cost $1.50. If Diana spent a total of $137, which of the following is a true statement?
A. Diana bought 16 boxes of pizza.
B. Diana bought more sodas than boxes of pizza.
C. Diana bought 6 boxes of pizza.
D. Diana bought an equal number of sodas and pizzas
Answers
Answer:
B. I think
Step-by-step explanation:
1.50 times 86 equals 129 witch would mean Diana bought 86 sodas
8 is equal to 1 pizza so Dianna could have bought 1 pizza
86>1
8+129 is 137 so I think the answer is B.

y = 5x - 6&y= -4x + 3
Use the Equal Values Method to solve for x and y
Answers
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

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.
Answers
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.

Step-by-step explanation:
There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday.
The number is students not trying out for football last Thursday is calculated as:
376 students - 47 students
= 329 students
The percent of 8th graders that did not try out for football is calculated as:
329 students/376 students × 100
= 329/376 × 100
= 87.5 %

B. The total cost increases by $2.50.
C. The total cost decreases by $1.
D. The total cost decreases by $2.50.
Answers
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
The is the multiplyer or change is the 2.5t
and when you graph it it will almost always be the slope of the line.
