Step-by-step explanation:
What is the value of 4p − 2, when p = 8?
What is the value of the expression when n = 3?
Answer:
The first one would be 30.
Step-by-step explanation:
First you multiply the 8 x 4, because the 4 and P are multiplying you just substitute the variable, and then substract 2.
What is the equation of a line passing through the point (4,-1) and parallel to the line whose equation is 2y-x=8
9514 1404 393
Answer:
2y -x = -6
Step-by-step explanation:
You can use the same x- and y-coefficients. You just have to change the constant on the right. Put the point values into the left expression to see the new constant.
2y -x = 2(-1)-(4) = -6
The parallel line is ...
2y -x = -6

Answer:
B. (-infinity, 1)
Step-by-step explanation:
Remember that domain is left to right, and range is down to up.
Question asks to find where the domain is increasing
Increasing means when the line increases
look left, the line extends infinitely in the negative direction: -infinity
There is a discontinuity at 1, and then the line decreases. So that would be the second point
The interval at which the domain is increasing is
Casey did a science experiment to find out which brand of popcorn popped the most kernels. The first brand had 123 kernels pop. The second brand had 108 kernels pop. To the nearest ten, about how many kernels popped in all?
Answer:
230
Step-by-step explanation:
The answer is 230 because if you add 123 and 108 together you get 231 but since we are rounding to the nearest 10 it would be 230 because 231 is closer to 230 than it is to 240.
if f(x) = 2x + 4 and g(x) = 6x - 10, find f(4) - g(2)
Answer:
f(4) - g(2) = 10
Step-by-step explanation:
[tex]f(x) = 2x + 4 \\ f(4) = 2 \times 4 + 4 = 8 + 4 = 12 \\ \\ g(x) = 6x - 10 \\ g(2) = 6 \times 2 - 10 = 12 - 10 = 2 \\ \\ f(4) - g(2) = 12 - 2 \\ \\ \huge \red{ \boxed{ f(4) - g(2) = 10}}[/tex]

What is the midpoint between the following two points
(3,-2) & (9,2)
A) (6,0)
B) (0,6)
C) (3,1)
D) (3,2)
Answer:
B, (6,0)
Take the average of the x values and the average of the y values:
(3+9)/2 = 6
(-2+2)/2 = 0
This means the answer (the average (midpoint) of the two points) is (6,0)

Can someone help me please!!
Answer:
y = (-3x/5) +1
Step-by-step explanation:
We know that the line passes through the point (-5 , 4)
AND
the slope is given to be -3/5
let's look at the slope a bit more
we know that the formula for slope of a line is Rise / Run
Which means that the rise of this line is -3 after spanning 5 units to the right
Hence, the line goes down 3 units after moving 5 units to the right
We know that to find the equation of a line through the point-slope equation, we need the slope as well as the y-intercept of the line
since we are already given the slope, we need to find the point where the line intersects the y-axis
Now, back to the given point the line passes through
this point has a x - coordinate of -5 and we know that after moving 5 units to the right, the line moves 3 units downwards
So, if the line moves 5 units to the right from the given point, it will reach the y- axis and we know that it's y-coordinate will decrease by 3
Hence, the y-intercept will be 3 units below the given y -coordinate
y - intercept = (4 - 3) = 1 = y-intercept
Now, using the slope-intercept formula to get the equation:
y = (slope)*x + (y-intercept )
y = (-3/5)x + (1)
y = (-3x/5) + 1

WILL GIVE BRAINLIEST! What is the equation of the line passing through the points (4, 7) and (7, 13) in slope-intercept form?
Answer:
y = 2x - 1
Step-by-step explanation:
To get slope:
m = y2 - y1 / x2 - x1
m = 13 - 7 / 7 - 4
m = 6 / 3
m = 2
To get y-intercept:
y = mx + b
13 = 2(7) + b
13 = 14 + b
13 - 14 = b
-1 = b
Put it together:
y = 2x - 1
i just need x and y please
Answer:
Step-by-step explanation:
Since you know both triangles are congruent, you can say that the corresponding sides are equal. For example, you can say:
17x+3 = 57
because they are corresponding sides of both triangles. To further solve the equation:
17x = 54 --> x = 54/17 --> 3 3/17
Same thing for Y. lines PX and FD are congruent, so, you can say:
4y-3 = 54
4y=57
y= 14.25

Factor (5x − 6)2 − (4x − 3)2.
Answer:
9( x-3) (x-1)
Step-by-step explanation:
(5x − 6)^2 − (4x − 3)^2
This is the difference of squares a^2 - b^2 = ( a-b) (a+b)
(5x − 6)^2 − (4x − 3)^2 where a = 5x-6 and b = 4x-3
( 5x-6 - (4x-3)) ( 5x-6 +(4x-3)
Distribute
( 5x-6 -4x+3) ( 5x-6 +4x-3)
Combine like terms
(x-3) ( 9x-9)
