Answer:
y = -9
Step-by-step explanation:
Step 1: Write equation
y + 7 = -2
Step 2: Solve for y
Subtract 7 on both sides: y = -9Step 3: Check
Plug in y to verify it's a solution.
Substitute: -9 + 7 = -2Add: -2 = -2In exercise teacher wants each student in her class to have at least 48 ft.² of space on the floor. What is the largest number of student she will allow in a classroom with a student exercise area of this size?
Answer: D. 50 students
pls give me brainliest.
Step-by-step explanation: First we find the area of the classroom which is worked out below and it is the shape of a rectangle;
Area of a rectangle = Length * Breadth
= 60 ft * 40 ft
= 2400 ft²
Now to find the number of students that she will allow in the classroom, we have to divide the area of the classroom which is 2400 ft²by the amount of space allocated to each student which will be;
=
= 50
This means she will allow 50 students into her class.

Answer:
Normally it would be the second option, but I believe the question writers made a mistake. Parallel lines always have the same slope (hence 2x), but have to have different y intercepts. I'm afraid to say none of the above.

i already have an answer but i need other answers too so i can check whether mine is wrong or not..
x ^ 2–2x + 1
by splitting this equation
x ^ 2 - x -x + 1
there are a two terms x ^ 2 - x and - x + 1
we take x is common from first and -1 is common from second
x ( x - 1 ) and -1 ( x-1 )
the quadratic roots are (x-1) and (x-1)
x - 1 = 0
x = 1 in both
Therefore , the quadratic roots are 1 , 1 .

What is the length of segment BC?
The length is 10 because this is a right triangle and based on the pythagorean theorem, the sum of the squares of the legs equals the square of the longest side.
6 squared plus 8 squared is 100, which is 10 squared.
The answer is 10.
Answer:
C. 10
Step-by-step explanation:
The Pythagorean Theorem states that a² + b² = c²
a² can be found by multiplying 6 by 6, which is 36
b² can be found by multiplying 8 by 8, which is 64
36 + 64 = 100.
The square root of 100 is 10, you can double-check this because 10 x 10 = 100
Because of this, we know that the line segment BC is equal to 10

SAT Prep) In the figure, what is the value of x? A. 30° B. 50° C. 15° D. 20°
Answer:
D. 20° Can I get brainliest please :)
Step-by-step explanation:
You can see their is a 90° angle, and angles across from each other are equal so them together is 180° and you know the whole thing is 360° so you can do
360°-180°=180°
then you have the x's we still know that angles opposite each other are the same so if we add all those angles together we get
x+x+2x+30°+2x+30°
simplify it
6x+60°
then we know what we have left is 180° so we do numbers to numbers
180°-60°=120°
now we have
6x=120°
simplify it
x=20°
The value of x is 20°. Option b is correct.
Value of angle x is to be determine.
it can be defined as the measure of one line tilt over other line.
Here, the sum of angle is 180°
x+90+2x+30=180
3x =180-120
3x = 60
x = 20
Thus, the value of x is 20°.

what does i2x + 3(x - 5) = 20 equal
Answer:
x=7
Step-by-step explanation:
2x+3(x-5)=20
2x+3x-15=20
5x-15=20
5x=35
x=7
Answer:
x = 5
Step-by-step explanation:
2x + 3(x - 5) = 20
simplify
5x - 5 = 20
get the variable and the number on different sides
5x - 5 + 5 = 5x
20 + 5 = 25
5x = 25
now divide each side by 5
5x / 5 = x
25 / 5 = 5
x = 5

Jerome found the lengths of each side of triangle QRS as shown, but did not simplify his answers. Simplify the lengths of each side to answer the question. Which statement about triangle QRS is true?
a. Triangle QRS is an equilateral triangle because QR = RS.
b. Triangle QRS is an isosceles triangle because QR = QS.
c. Triangle QRS is a scalene triangle because all sides have different lengths.
d. Triangle QRS is an isosceles triangle because QR = RS.
Answer:
D. Triangle QRS is an isosceles triangle because QR = RS.
Step-by-step explanation:
Find the length of each side of the triangle using the formula for calculating the distance between two points.
D = √(x2-x1)²+(y2-y1)²
For side RS
R(0,0) and S(5, -3.322)
RS = √(5-0)²+(-3.322-0)²
RS = √25+11.035684
RS = √36.035684
RS = 6.0029
For side RQ
R(0,0) and Q(-3, -5.2)
RQ = √(-3-0)²+(-5.2-0)²
RQ = √9+27.04
RQ = √36.04
RQ = 6.0033
For side QS
Q(-3,-5.2) and S(5, -3.322)
QS = √(5+3)²+(-3.322+5.2)²
QS = √64+3.526884
QS = √67.526884
QS = 8.22
From the calculation it can be seen that RS=QR

Given the two functions below, tell me what type of graphs they are and
how p(x) differs from g(x)
p(x)=8x^2
g(x) = x^2
Answer:
Step-by-step explanation:
p(x) = 8x^2 is an increasing exponential curbed graph which starts from quadrant 2 , passes through the point (0, 8) on the y axis and rises steeply to the right.
g(x) = x^2 is a parabola ( shaped like a U) which has a minimum value at (0, 0).
and opens upwards either side of the y-axis. This type of curve is called a parabola.
