Answer:
2
Step-by-step explanation:
perpendicular means the opposite inverse of a slope. So -1/2 will become 2/1 or simply 2.
opposite means the sign will change, negative becomes positive and positive becomes negative.
inverse flip numerator and denominator.
[tex]\huge\boxed{Hi\;there!}[/tex]
★Perpendicular lines have slopes that are opposite reciprocals.
This means we take a number, change its sign, and then, flop it over:
[tex]\displaystyle-\frac{1}{2}[/tex]
[tex]\displaystyle\frac{1}{2}[/tex]
[tex]2[/tex]

What's a rule you could apply to any number that would predict which denominators will terminate
9514 1404 393
Explanation:
The decimal equivalent of a fraction will terminate if its denominator can be factored using only the prime numbers 2 and/or 5.
1/4 = 1/(2·2) will terminate
1/15 = 1/(3·5) will not terminate

f(x) = 2x-2+5
Step-by-step explanation:
from,
f (x) = 2x-2+5
BUT x=-2
f (x) = 2 (-2)-2+5
= -4-2+5
= -6+5
= -1
so,
f (x) = -1

1
Answer:
its 14 or 1/4 as you said | if it is not fractions and is whole numbers it is 1
Step-by-step explanation:
1/4 is the smallest value out of all of them, making it the least probable to happen
if they are not fractions, it is 1 because that is the smallest value, making it the least probable

The graph shows how many apples Erin can pick if she maintains a constant rate. What is the linear equation for this relationship?
How many apples can she pick per hour? Drag numbers to complete the statements.
Numbers may be used once, more than once, or not at all.
Answer:
The answer is y=75x, Erin can pick 75 apples per hour
Step-by-step explanation:
Normally you'd find two points and then use rise over run, but since there's an exact point (75) over 1 in the x plane, you don't need to simplify as it's already done for you
Which equation represents the line that passes through the point (4, -5) and is perpendicular to the line x + 2y = 5?
Answer:
y = 2x - 13
Step-by-step explanation:
Equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is
y = 2x - 13

Answer:
64
Step-by-step explanation:
Which of the following values are solutions to the inequality 1 + 5x < 4?
Step-by-step explanation:
you cant add 1 to 5x, so subtract 1 on both sides leaving you with 1 + 5x < 4 that equals 5x < 3 -1 -1
then divide 5 from both sides 5x < 3 This leaves 5 5
you with x < 3/5

Answer:
X=85°....
Step-by-step explanation:
you do this by first acknowledging that in any triangle 180° will be present... so 40 + 45° equals 85°..this means that the other angle in the triangle will equal 95 degrees... now, in a line there's 180° present... that means 180 minus the 95 from the angle of c equals 85.

Answer:A
Step-by-step explanation:
The triangle ΔABC is rotated 180° about the origin, then the ΔA'B'C' is obtained.
What is a transformation of a point?A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.
Triangle ABC is congruent to Triangle A’B’C’.

What is the value of x?
2x+20
3(x-10)
Answer:
x = 50
Step-by-step explanation:
By the definition of vertical angles you can set these two equations equal to each other.
2x+20=3(x-10)
then, just simplify to get the correct answer by using order of operations.
2x+20=3x-30
x=50
