Complete the equation of the line through (-6, 5) and (-3, -3)
Answer:
y = -8/3x - 11
Step-by-step explanation:
(-6, 5) and (-3, -3)
Slope:
m=(y2-y1)/(x2-x1)
m=(-3-5)/(-3+6)
m=(-8)/3
m= -8/3
Slope-intercept:
y - y1 = m(x - x1)
y - 5 = -8/3(x + 6)
y - 5 = -8/3x - 16
y = -8/3x - 11

If the perimeter of a square is 20, find the length of a diagonal. Round your answer to the nearest tenth.
7.7
7.1
6.3
8.4
Answer:
option 2] 7. 1
Step-by-step explanation:
Perimeter of square is 20.
therefore,
[tex]perimeter \: = 4 \times side \\ therefore \: 20 = 4 \times side \\ \: \: \: \: \: \: side = \frac{20}{4} \: = 5 [/tex]
the diagonal and the Two adjacent sides of the square form a right angle triangle, so,
By hypotenuse theorem,
[tex] {iagonal}^{2} \: = {side1}^{2} + {side2 }^{2} \\ \: \: \: \: \: \: \: \: = {5}^{2} + {5 }^{2} \\ = 25 + 25....(as \: suare \: has \: equal \: sides \: i.e \: 5) \\ = 50 \\diagonal = \sqrt{50} \\ = \sqrt{25 \times 2} \\ = 5 \sqrt{2 } \\ = 5 \times 1.414 \\ = 7.07 \\ = approx \: 7.1[/tex]

what is the answer for 9k^2=225
9k² = 225
k² = 225 : 9
k² = 25
k = -5 and k = 5 because :
(-5)² = (-5) * (-5) = 25
5² = 5 * 5 = 25
Plz help!!! You identify the error the solve it correctly!!!!!
Answer:
You have to multiply the numbers diagonally not vertically.
So
10x = 7(350)
10x = 2450
x = 245
9514 1404 393
Answer:
different sides of the equation were multiplied by different numbersx = 245Step-by-step explanation:
There is a method of solving proportions that is called "cross multiply" or "cross multiplication". For a proportion like this it looks like each numerator is multiplied by the opposite denominator. In this problem, the result would be ...
7(350) = (10)x
While "cross multiplication" is a description of the appearance of what is happening, what is really happening is that both sides of the equation are being multiplied by the same value: the product of the denominators. This is in accordance with the multiplication property of equality, which requires you multiply both sides of the equation by the same value.
__
The error that was made in this problem is that each numerator was multiplied by its own denominator. Effectively, that multiplied the left side of the equation by 10² = 100, and the right side of the equation by 350² = 122500. This is in direct violation of the multiplication property of equality, so guarantees the value found for x will be wrong.
__
While "cross multiply" is an instruction often given for solving proportions, it causes an extra step to be needed in solving a proportion like this one. All that is really needed is to multiply both sides of the equation by the denominator under the variable. Here, that means multiplying both sides of the equation by 350.
Correct solution
[tex]\dfrac{7}{10}=\dfrac{x}{350}\\\\350\cdot\dfrac{7}{10}=350\cdot\dfrac{x}{350}\\\\\\35\cdot 7=\boxed{x=245}[/tex]

Answer:
y=8x
Step-by-step explanation:
X is the input, Y is the output. The answer describes that whatever X is, if you times it by 8, you get Y. It can't be "x + 14" because that only works with the first number given. If you do Y = X + 14, 6 doesn't equal 48.
5x + 8 =33 what is the x
A vision insurance company selects a SRS of 300 clients who wear contact lenses. They randomly assign 200 clients to the experimental group to receive an app that promotes contact lens hygiene. The remaining 100 clients form the control group. Suppose that without the app, 96%, percent of their clients with contact lenses would have healthy eyes for the year, and that with the app, 99%, percent would have healthy eyes.
After a year, the insurance company looks at the difference (Experimental−Control) between the proportions of clients with healthy eyes in each group.
What will be the shape of the sampling distribution of the difference in sample proportions, and why?
A
Approximately normal, because we expect 288 healthy and 12 not-healthy in both groups, and all of these counts are at least 10.
B
Approximately normal, because we expect 192 healthy and 20 not-healthy eyes for the experimental group, and 96 and 40 for the control group, and all of these counts are at least 10.
C
Not normal, because we expect fewer than 10 clients with healthy eyes in both groups.
D
Not normal, because we expect fewer than 10 clients with not-healthy eyes in both groups.
Answer:
NO, its D: Not normal, because we expect fewer than 101010 clients with not-healthy eyes in both groups.

Find the area of the parallelogram
Answer:
A=32
Step-by-step explanation:
area of parallelogram formula
A=b*h
A=8*4
A=32
Answer:
32
Step-by-step explanation:
Intuition for why the area of a parallelogram is A = b h A=bh A=bh. The formula for the area of a parallelogram is base times height, just like the formula for the area of a rectangle.
A=bh=8·4=32

Write the equation of the graph in slope intercept form
Answer:
1/2x+3
For the slope you have to on the 2,2 you have to go up and over to the next dot on a line and for the y intercept you just have to find it on the line and if it was on the bottom do a -3 rather than a +3.

Solve to find the answer of blue pills Mr body took: number of blue pills, b, mr mattics give him was 3 more than the number of green pills,g, total number of pills took was 17, 11 blue pills to kill
Answer:
Mr body took 9 blue pills
Step-by-step explanation:
Total number of pills consumed = 17
Number of blue pills, b = 11
Number of blue pills, b = g + 3
So that,
b = g + 3
11 = g + 3
g = 8
Total number of pills recommended = b + g
= 11 + 8
= 19
Total number of pills consumed = 17
Thus,
Number of blue pills consumed = 17 - 8
= 9
Therefore, Mr body took 9 blue pills.
You are a laboratory technician. You are filling spherical flasks with a salt solution and then putting them into boxes. Each flask has a volume of 113.04 cubic inches.
Rounded to the nearest tenth of an inch, what is the radius of one flask?
3.0
3.6
5.2
6.4
6.9
Answer:
3.0 inches
Step-by-step explanation:
The formula for the volume of a sphere is
V = 4/3 × π × r³
V = 113.04 cubic inches
To find r
r = (3V/4π)⅓
r = (3 × 113.04/4 × π )⅓
r = 3.0 inches
The radius of one flask = 3.0 inches
