Answer:
it is 4+4/2
Step-by-step explanation:
you use pemdas which is
parenthesis, exponents, multiplication, division, addition, and subtraction.
now you go from left to right so if you see division before multiplication then you will do division first because addition and subtraction and multiplication and division are equal so multiplication is not more important than division and addition is not more impirtant than subtraction.
so basically you do 4/2 which is 2
and
4+2=6

In the following function defined by an equation in the form y = ax^2+bx+c, identify the values of a, b, and c.
y = 5x^2 + 2x - 1
a = -1, b = 2,c = 5
b. a = -2,b = 5.c - 1
c. a = 1, b = 5,c = 2
d. a =5, b = 2, c = -1
Answer:
d
Step-by-step explanation:
by substitution what is before x² is considered as a
what is before x is b and the number alone(without x) with it's sign included is c

Answer:
50126.978033
Step-by-step explanation:
12000(1.10)^15
12000 is your starting amount.
You earning 10% investment so add 1 to that 10% and make it a decimal = 1.10
Raise is to 15 years because it's compounded for 15 years.

Plse help so confused
Answer:
Step-by-step explanation:
As we can see that Line WL is a straight line that the angles that make up it like Angle HJW and Angle GJH and Angle LJG all equal to 180 degrees
Angle HJW = 18 degrees
ANGLE GLH = 90 degrees (we know that because there is a little square)
Angle LJG = 9x
Now lets set up the equation:
Angle HJW + Angle GLH + ANGLE LJG = 180 degrees
18 + 90 + 9x = 180
108 + 9x = 180
9x = 72
x = 8
So x = 8
Hope that helps!
Solve the system of equations:
x+3y-z=9
2x+9y+4z=12
x+4y+z=7
[i] … … … x + 3y - z = 9
[ii] … … … 2x + 9y + 4z = 12
[iii] … … … x + 4y + z = 7
Eliminate z by combining …
• … 4 times equation [i] and equation [ii] :
4 (x + 3y - z) + (2x + 9y + 4z) = 4•9 + 12
(4x + 12y - 4z) + (2x + 9y + 4z) = 36 + 12
6x + 21y = 48
2x + 7y = 16
• … equation [i] and equation [iii] :
(x + 3y - z) + (x + 4y + z) = 9 + 7
2x + 7y = 16
Since we ended up with 2 copies of the same equation, we have infinitely many solutions for x, y, and z. That is, we have infinitely many choices for x and y that satisfy 2x + 7y = 16, and consequently infinitely many choices for z to satisfy any of the 3 original equations.
We can parameterize the solution by letting, for instance, x = t; then the solution set is
x = t
2x + 7y = 16 ⇒ y = (16 - 2t)/7
x + 3y - z = 9 ⇒ z = t + 3 (16 - 2t)/7 - 9 ⇒ z = (t - 15)/7
where t is any real number.

What is the y-intercept ??? Please show step by step!!
Answer:
(0, 1)
Step-by-step explanation:
The y-intercept is where a graph intersects with the y-axis. The x-coordinate would be 0, and the y-coordinate would be any real number.
Given the information above, the y-intercept is (0, 1) or 1 because its x-coordinate is 0 and y-coordinate is a real number.
Answer:
y-intercept is (0,1)
Step-by-step explanation:
When we are looking at the chart we’re looking for a point where the x is 0 and the y is 1 which is the definition of y-intercept, where the line intersects only with the y-axis
We can see this in the chart but if that point is not on there, we have another way to find it.
This is the formula, point-slope form.
(Math people are not that creative, you use it when you have the slop and a point)
First, we need to find the slope
We do this by taking two points and using the formula y2-y1 over (/) x2-x1
So our formula is y2-y1/x2-x1.
If you pick two random points, (We will use 0,1 and 1,3) and subtract them from each other, you have the slope
3 is y2 because it’s a y point and its the second point and 1 is our other point because its a y point and its the first y point
So our equation now is 3-1/x2-x1
Now we have to sub in for the x’s
Do the same thing and our equation now is…
3-1/1-0
This gets us to 2/1 which is obviously 2.
Now we have our slope so we just have to fill in for the point.
Point slope form uses the model y-y1=m(x-x1)
So we use our same two points and get
Y-1=2(x-0)
Solve this out to Slope intercept form which will give us our y-intercept.
This gets us to y=2x+1 so our y-intercept is clearly still 1!

The area of a circular swimming pool is approximately 18 m2. so Which is the best estimate of the radius (
Answer:
i think the radius is 9 because the diameter of the pool is 18 and the pool is in the shape of a circle so 9 is the best estimate.

What is the equation of the line that passes through the point (-2, 7) and has a slope of zero?
FX-7
6 y = -2
H x = -2
y=7
Answer:
y = 7
Step-by-step explanation:
Linear equation: y = mx + b
where m is the slope and b is the y-intercept
If the line has a slope of zero, then: y = b
As the line passes through the point (-2, 7), then y = 7 since the y-coordinate of the point is 7
a A model of a ship is 6 inches long. The actual ship is 550 feet (6,600 inches). Find the scale factor used for the model.

Help, please!!! Coordinate planes: find the distance. Thanks for helping!
Answer:
The answer would be 11.3
Step-by-step explanation:
All you have to do is figure out how far one is from the other so from 7.8 I went back to 0 of course the Y coordinate stays the same. So then you get the -3.5 make it a positive so just 3.5 and then add to 7.8 to get 11.3
Hope this helped.

Julia has determined that CE is perpendicular bisector of AB. The next step of a valid proof would be: B. AC = BC based on the perpendicular bisector theorem.
What is the Perpendicular Bisector Theorem?The perpendicular bisector theorem states that if a point is located on a segment (perpendicular bisector) that divides another segment into two halves, then it is equidistant from the two endpoints of the segment that is divided.
Thus, since Julia has determined that CE is perpendicular bisector of AB, therefore the next step of a valid proof would be: B. AC = BC based on the perpendicular bisector theorem.

no
Answer:
No
Step-by-step explanation:
