Help please I’m taking my iready testtt
suppose a+b=10 and the value of a increases by 1. If the sum remains the same, what must happen to the value of b?
Answer:
[tex]b[/tex] decreases by [tex]1[/tex]
Step-by-step explanation:
If the value of [tex]a[/tex] increases by [tex]1[/tex] and the sum remains the same, then the value of [tex]b[/tex] decreases by [tex]1[/tex].
Example:
Suppose [tex]a=7[/tex] and [tex]b=3[/tex].
[tex]a+b = 10[/tex]
[tex]b = 10-a[/tex] (minus [tex]a[/tex] on both sides)
Now, let [tex]a = 8[/tex] ([tex]a[/tex] has increased by [tex]1[/tex]):
[tex]b = 10-8[/tex]
[tex]=2[/tex]
From the comparison of the previous value of [tex]b[/tex] to the current value of [tex]b[/tex], the value of [tex]b[/tex] has decreased by [tex]1[/tex].
Hope this helps :)

find the equation for the parabola with vertex (4,6) and focus (4,9) .
Answer:
Equation of the parabola: 12y−72=(x−4)212y−72=(x−4)2 or y=x212−2x3+223y=x212−2x3+223.
Vertex form: y=(x−4)212+6y=(x−4)212+6.
No intercept form.
Vertex: (4,6)(4,6).
Focus: (4,9)(4,9).
Eccentricity: 11.
Directrix: y=3y=3.
Latus rectum: y=9y=9.
The length of the latus rectum: 1212.

Garvin is painting the outside of the house. One can of paint will cover 2/9 of the house.Garvin has already used 4 can of paint . How much surface is already painted
Answer:
4 cans of paint will cover 8/9 of the surface
Step-by-step explanation:
One can of paint covers 2/9 of the house.
Garvin has used 4 of those cans.
To get the fraction of the whole surface that has been covered by those 4 cans of paint, we can multiply, following the logic below:
1 can of paint covers = 2/9 of the surface
4 cans of paint will cover = x of the surface
x = 4 X 2/9 = 8/9
Therefore, 4 cans of paint will cover 8/9 of the surface

can someone help me plz 2a+1=1
Answer:
0
Step-by-step explanation:
2a+1=1
2a=0
--- ---
2 2
a=0
Answer:
A=0
Step-by-step explanation:
2a+1=1
2a=1-1 (i moved +1 to the other side ...coz our goal is to isolate "a", and in order to do this, look for numbers that are freer)(moving the +1 to the other side made it -1)(you just need to remember that when we move any number to the other side it will claim its opposite operation so +1 will turn to -1)
2a=0 (1-1=0)
a=0/2 (now, 2 is being multiplied with a, and to isolate "a" we move 2 to the other side, and this will make to divide ((because the opposite of multiplication is division)) )
a=0 (the ans!)
elias is training for a marathon. The table shows the total number of miles he has run each 0 I
1 I 9 sorry i could not make a line so i use this > I for a line Please what is the rate.
2 I
3 I 21
4 I
5 I 33
Answer:
rate of 6
Step-by-step explanation:
Either Table A or Table B shows a proportional relationship.
Table A
x −2 −1 0 1
y 2 3 0 5
Table B
x −1 0 1 2
y −3 0 3 6
Plot the points from the table that shows a proportional relationship.
Answer:
the answer is table B
Step-by-step explanation:
Answer:
Table B shows a proportional relationship
Explanation:
In a proportional relationship two quantities vary directly with each other.
So,
y ∝ x
y = kx
Where, k is the constant of variation.
The ordered pairs of table A are (-2,2), (-1,3), (0,0) and (1,5).
From these ordered pairs we can conclude that the value of y-coordinate is not changing according to the x-coordinate because the values of x increased by 1 for each ordered pair but the value of y is not increasing in the same proportion..
The ordered pairs of table B are (-1,-3), (0,0), (1,3) and (2,6). The value of y increasing at a constant rate 3 and the value of y-coordinate is 3 times of x-coordinate.
Choose any two ordered pairs of table B. Let the two points are (0,0) and (1,3).
The proportional relationship is defined as
y = 3x
Therefore, 3 is the constant of variation and rate of change.
So, Table B shows a proportional relationship.

Answer:
3 and 8
Step-by-step explanation:
3 and 8 because 8 can only divide by 2 or four and get 4 and 2, and 3 can not get to any of these number.
Carson is a high school student with two part-time jobs. He earns $6 per hour for babysitting, and he earns $8 per hour doing clerical work for his father's business. His goal is to earn at least $96 a week, but because of school, he does not want to work more than 15 hours each week. Suppose Carson worked as a babysitter for 5 hours one week. What is the minimum number of full hours he would need to work at his father's business to earn at lease $96 that week?
Step-by-step explanation:
Step one:
let the hours for babysitting be x
and the hours for doing clerical be y
we are told that Carson would like to earn $96 weekly
She babysits for $6 per hour
and earned $8 per hour doing clerical work
6x+8y=96---------------1
Carson cannot work more than a total of 15 hours per week
5x+y≤15-------------2
The system of equation for the situation is
6x+8y=96
5 x+y≤15
y=15-5 x
put y=15-5 x in eqn 1
6x+8(15-5 x)=96
6x+120-40x=96
collect like terms
6x-40x=96-120
-34x=-24
x=24/34
x=0.7
Approximately 1 hour babysitting
put x= 0.7 in 5x+y≤15
5(0.7)+y≤15
3.52+y≤15
y≤15-3.52
y=11.4
Approximately 11 hours doing clerical work
