can u help me plzzzz.
Answer:
A
Step-by-step explanation:
A is the only one that passes the vertical line test
(the vertical line test is when you can draw a line anywhere on the graph and it only touches the graph once) (another way of thinking about this is "no two points can have the same value on the x axis)
why does he look so off
He on that good shi...............
Pls help meeeee

In September, Louise planted a tree. Every month, the tree Louise planted grew 2 inches. What would the constant of proportionality of the line be?
Answer:
1/2
Step-by-step explanation:
Tree grow 2 inches per month
Let :
Month = m ; height increase, h
m α h
m = kh
k = proportionality constant
Where ; m = 1 ; h = 2
1 = 2k
1/2 = 2k/ 2
k = 1/2
Answer:1/2
Step-by-step explanation:
Tree grow 2 inches per month
Let :
Month = m ; height increase, h
m α h
m = kh
k = proportionality constant
Where ; m = 1 ; h = 2
1 = 2k
1/2 = 2k/ 2
k = 1/2

9514 1404 393
Answer:
10°, 80°
Step-by-step explanation:
Setup
Let x and y represent the measures of the two acute angles in the right triangle.
From your knowledge of right triangles, you know the two acute angles are complementary:
x + y = 90
The problem statement gives you another relation:
x = 2(y + 30) . . . . twice the sum ...
__
Solution
The second equation gives you an expression for x that can be substituted into the first equation.
(2(y +30)) + y = 90
3y +60 = 90 . . . . . . . . collect terms
3y = 30 . . . . . . . . . subtract 60
y = 10 . . . . . . . . divide by 3
x = 2(y +30) = 2(40) = 80
The two angles are 10° and 80°.

Lucy solves 1.8 ÷ 0.3 using the work below.
Lucy's work is incorrect. Explain Lucy's mistake and write what the correct answer should be. Please write your response in complete sentences.
Answer:
Lucy's mistake is that she didn't move the decimal in 1.8 as well. The correct answer should be 6.
Step-by-step explanation:
Since Lucy multiplied 0.3 by 10, she also needed to multiply 1.8 by 10 to keep the equation proportional.

what is the value of x
Answer:
x=6
Step-by-step explanation:
Because these lines are parallel, that means these angles are congruent, so you can set up an equation because they are equal to each other.
110=19x-4
add 4 to both sides
114=19x
and divide by 19
6=x
or
x=6

Question 1 of 10 Enter the slope-intercept equation of the line that has slope 4 and y-intercept (0, 11).
Answer:
y=4x+11
Step-by-step explanation:
The formula for slope intercept is y=mx+b
m= slope
b= y intercept
hence, y=4x+11

Pedro is getting balloons for his grandmother's birthday party. He wants each balloon string to be 12 feet long. At the party store, string is sold by the yard. If Pedro wants to get 52 balloons, how many yards of string will he need? 1 foot = 1 3 yard
Answer:
Total length of string required in yards [tex]8112[/tex] yards
Step-by-step explanation:
The length of the string attached with each balloon is equal to [tex]12[/tex] feet
In the party total number of balloon used is equal to [tex]52[/tex] balloons
The total length of the string required
Length of string used in one balloon * total number of balloons
[tex]= 12 * 52 = 624[/tex] feet
1 feet is equal to 13 yards
Total length of string required in yards [tex]13 * 624 = 8112[/tex] yards

Leg a = x
Leg b = 12
Hypotenuse c = 13
Step 2: Solve for x
