Answer:
x=1
Step-by-step explanation:
for y²=4ax
directrix is x=-a
for y²=4x ,directrix is x=-1
for y²=4(x-2), shift directrix 2 units right.
so directrix is x=-1+2=1
so for (y+4)²=4(x-2) directrix is x=1

Answer:
The correct option is;
The points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects
Step-by-step explanation:
With the assumption that that the question meant that ΔACD and ΔBCD are congruent, we have;
Segment [tex]\overline {AC}[/tex] is congruent to segment [tex]\overline {BC}[/tex] by Congruent Parts of Congruent Triangles are Congruent, CPCTC
Similarly, segment [tex]\overline {DA}[/tex] is congruent to segment [tex]\overline {DB}[/tex] by Congruent Parts of Congruent Triangles are Congruent, CPCTC
Therefore, the points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects

2. David is a salesperson who sells computers at an electronics store. He is paid a $15 commission for every computer sale he makes and he also makes a guaranteed base pay of $80 each day. Write an equation for P. in terms of x, representing David's total pay on a day on which he sells x computers. Your answer
Answer:
[tex]y=15x+8[/tex]
Step-by-step explanation:
Step one:
guaranteed base pay= $80 each day
$15 commission for every computer sale
let the number of computers he sales be x
and let the total amount he makes be y
Step two:
Required
the expression for the total
The total can be modeled after the equation of a line
[tex]y=mx+c[/tex]
[tex]y=15x+8[/tex]
$99 to $74 increase or decrease
Answer:
decrease, 25% percent change
Step-by-step explanation:
99 - 74 = 25 25 / 99 = 0.25 0. 25 × 100 = 25.25%From $99 to $74, it is 25.25 percent decrease.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, $99 and $74.
From 99 to 74 it is decreased
Difference 99-74=25
Now, 25/99 ×100
= 0.2525×100
= 25.25%
Therefore, from $99 to $74, it is 25.25 percent decrease.

A function is a relationship between inputs where each input is related to exactly one output.
f(1) = 97
f(2) = 194
f(3) = 291
Where f(x) is the calories burned.
x is the number of miles walked.
Yes, the given relation in the table is a function.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Function:
Miles walk = input
Calories burned = output
We know that,
A function can have many-to-one and one-to-one.
A function can not have one-to-many.
Now,
From the table,
f(1) = 97
f(2) = 194
f(3) = 291
We see that the relation is a function.
The relation is a one-to-one relation.
Thus,
The given relation in the table is a function.

Angle B is an acute angle in a right triangle. What is a reasonable approximation for angle B if the ratio for the opposite leg divided by the hypotenuse is 0.67?
Answer:
42.1 degrees
Step-by-step explanation:
- since we have a opposite/hypotenuse ratio, that means we used sin x = o/h
- this means, sin x = 0.67
so, x = [tex]sin^{-1[/tex](0.67) {sin inverse}
x = 42.06 degrees, i rounded it up to 42.1 but its up to you (or according to the question)
i’ve already got 9 i believe, but could somebody please help with 10? it’s point slope form but i’m not understanding.
