Bobby should grow an amount greater than 70-61 = 9 inches to become taller than 70 inches. Therefore, the correct answer is that Bobby must grow an amount of x> 9 inches to be taller than 70 inches.
Answer:
y=-1/4x+1
Step-by-step explanation:
Hi there!
We're given the point (-8,3) and a slope of -1/4
lines are typically written in the formula y=mx+b, where m is the slope and b is the y intercept
as we are already given the slope, we can substitute its value into the equation
substitute -1/4 as m
y=-1/4x+b
now we need to find b
as the equation passes through the point (-8,3),we can use it to solve for b
substitute -8 as x and 3 as y
3=-1/4(-8)+b
multiply
3=2+b
subtract 2 from both sides
1=b
substitute 1 as b
y=-1/4x+1
First, you subtract 28 from 100 then divide that by 12 which would give you 6. so, X>6
Answer:
The no. of students that play at least one instrument = 448
Step-by-step explanation:
Total number of students surveyed = 480
Students play piano = 253
Students play harp = 268
Students play both harp & Piano = 73
Thus number of student surveyed that they play at least one of the instrument = (Students play piano) + (Students play harp) - (Students play both devices)
= 253 + 268 - 73
= 448
The <em>error </em>made by Kaitlyn when solving the system of equations is in step 2. Her solution will be incorrect.
The right option will be: <em>No, she made an </em><em>error in step 2</em><em>. She should have found y = 0. 5.</em>
Given the system of linear equations:
-3x + 2y = 8 ---> eqn. 1
3x + 2y = -6 ---> eqn. 1
<em>First add both equations together:</em>
Step 1: 4y = 2
<em>Next, divide both sides by 4:</em>
Step 2: y = 2/4
y = 0.5
- Kaitlyn got y = 2 instead of 0.5 in this second step. The solution she would get will be incorrect since an error has occurred here.
Therefore, the <em>error </em>made by Kaitlyn when solving the system of equations is in step 2. Her solution will be incorrect.
The right option will be: <em>No, she made an </em><em>error in step 2</em><em>. She should have found y = 0. 5.</em>
