Answer:
y = 4x - 2
Step-by-step explanation:
Y-intercepts cross the y-axis at x = 0. So, we can plug (0 , -2) into an equation with m = 4.
-2 = 4(0) + b
-2 = b
y = 4x - 2
Which of the following is a solution to this inequality?
y > 1/2x + 2
Answer:
We conclude that only (1, 4) satisfies the inequality.
Thus, (1, 4) is a solution to this inequality.
Hence, option A is correct.
Step-by-step explanation:
Given the inequality
y > 1/2x + 2
FOR (1, 4)
y > 1/2x + 2
substituting x = 1, and y = 4
4 > 1/2(1) + 2
4 > 1/2+2
4 > 5/2
TRUE!
Reason: It is true because 4 is indeed greater than 5/2
Thus, (1, 4) satisfies the inequality.
Therefore, (1, 4) is a solution to this inequality.
FOR (-1, 1)
y > 1/2x + 2
substituting x = -1, and y = 1
1 > 1/2(-1) + 2
1 > -1/2+2
1 > 3/2
FALSE!
Reason: It is false because 1 can not be greater than 3/2
Thus, (-1, 1) DOES NOT satisfy the inequality.
FOR (2, 3)
y > 1/2x + 2
substituting x = 2, and y = 3
3 > 1/2(2) +2
3 > 1+2
3 > 3
FALSE!
Reason: It is false because 3 can not be greater than 3.
Thus, (2, 3) DOES NOT satisfy the inequality.
FOR (0, 2)
y > 1/2x + 2
substituting x = 0, and y = 2
2 > 1/2(0) +2
2 > 0+2
2 > 2
FALSE!
Reason: It is false because 2 can not be greater than 2.
Thus, (0, 2) DOES NOT satisfy the inequality.
Therefore, we conclude that only (1, 4) satisfies the inequality.
Thus, (1, 4) is a solution to this inequality.
Hence, option A is correct.

Write an equation in point-slope form of the line that passes through the point (−6, 6) and has a slope of m=32
Answer:
y = 32x + 198
Step-by-step explanation:
The fastest way to go about this is to establish "m" and plug in the coordinates you want.
y = 32x + b
6 = 32 (-6) + b
6 = -192 + b
198 = b
y = 32x + 198

Write the algebraic expression 9r+2 as a verbal expression
Answer:
We conclude that the algebraic expression 9r+2 can be verbally expressed in many ways such as:
Two more than 9 times a number, r.9 times a number, r, increase by 2.Step-by-step explanation:
Given the algebraic expression
9r+2
We know that 9r is the product of 9 and 3.
Thus,
9r+2 can be verbally expressed in many ways such as:
Two more than 9 times a number, r.
or it can be also verbally expressed such as:
9 times a number, r, increase by 2.
Therefore, we conclude that the algebraic expression 9r+2 can be verbally expressed in many ways such as:
Two more than 9 times a number, r.9 times a number, r, increase by 2.helppppp pleaseeeeeee

out of these numbers which of them differ by 46. 29,17,38,71,35,63,24
Answer:
71
Step-by-step explanation:
Add 46 to each number, see if the sum is in the list. In the set of 7 numbers listed, two of them are even (24 and 38), and the other 5 numbers are odd
71
We do not need to look at all differences.
We need to find two numbers fairly far appart,
and not all look promising.
You could look at approximate differences,
or you could look at the last digit.
71-35 and 63-17 are the only promising differences,
because 71 and 63 are the only numbers large enough to be 46 more than another number in that list,
and when you calculate the last digit you calculate
11-5=6 and 13-7=6.
71-35=36

Simplify the expression (3.5x - 2.7y) + (-12.8x + 15.8y)
Answer:
-9.3x + 13.1y
Step-by-step explanation:
(3.5x - 2.7y) + (-12.8x + 15.8y) = 3.5x - 2.7y - 12.8x + 15.8y =
= 3.5x - 12.8x - 2.7y + 15.8y = (3.5 - 12.8)x - (2.7 - 15.8)y =
= -(12.8 - 3.5)x + (15.8 - 2.7)y = -9.3x + 13.1y
because
-(-a) = a
-(a + b) = -a - b
-(a - b) = -a + b = b - a
a + (-b) = a - b

However if you took m and replaced it with 10
10-8[tex]\leq[/tex]2 and simplified

Write and graph an equation in two variables that shows the relationship between the time and the distance.
Moves 15 meters in 1 second.
Answer:
The relation between the time and the distance will be:
y = 15x
The graph of the equation y = 15x is attached below.
Step-by-step explanation:
We know that the equation of linear function in two variables in the slope-intercept form is
y = mx+b
where
m is the rate of change or slope b is the y-interceptLet y be the distance
Let t be the time
Given that the object moves 15 meters in 1 second.
Thus, the rate of change or slope = m = 15
As there is no initial condition in our case.
Thus the y-intercept b = 0
Now, substituting m = 15 and b = 0 in the linear function
y = mx+b
y = 15x + 0
y = 15x
Therefore, the relation between the time and the distance will be:
y = 15x
The graph of the equation y = 15x is attached below.
Examples:
Calculate the distance in 1 second
put x = 1 in the equation
y = 15(1) = 15 meters
Calculate the distance in 10 second
put x = 10 in the equation
y = 15(10) = 150 meters
