Answer:
y =-x-3
Step-by-step explanation:
slope intercept/ y-intercept form is y=mx+b
you have to isolate y here
x+y=-3 subtract x from both sides
y=-x-3
There are 20 students in Mrs. Williams' class, and 1/5 of the class has their own cellphone. Of this group of students, 1/2 of them are allowed to use social media. How many of the students have a
cellphone and can use social media?
Answer:
2
Step-by-step explanation:
Only 1/5 of Miss Williams' class has a cell phone, so we work this out by dividing the number of students by 5
20÷5=4
Out of this group of 4 students, only 1/2 are allowed to use social media
4÷2=2
This means that only 2 pupils have a phone and are allowed to use social media at the same time.
If you need to express this in fraction form, it would be 1/10 of the class

On a coordinate plane, a line is drawn between points (negative 4, negative 3) and (negative 1, 4).
Use the Pythagorean theorem to find the distance on the coordinate plane.
a2 + b2 = c2
What is the distance between the two points?
StartRoot 20 EndRoot
StartRoot 40 EndRoot
StartRoot 45 EndRoot
StartRoot 58 EndRoot
Answer:
StartRoot 58 EndRoot
Step-by-step explanation:
Given the coordinates (-4, -3) and (-1, 4)
To get the distance between the two points, we will use the formula:
D =√(y2-y1)²+(x2-x1)²
From the coordinates, x1 = -4, y1 = -3, x2 = -1 and y2 = 4
Substitute
D =√(4-(-3))²+(-1-(-4))²
D = √(4+3)²+(-1+4)²
D = √7²+3²
D = √49+9
D = √58
Hence the correct option is D
StartRoot 58 EndRoot
Answer:
D. 58

A tailor uses 12 meters of fabric daily. How many centimeters of fabric will he use in two weeks?
Length of fabric a tailor uses a day = 12 meters
Length of fabric a tailor uses a day =
2 weeks = 14 days
Length of fabric a tailor will use in 14 days =
= 14 × 12
= 168 meters
Therefore , a tailor will use 168 meters of fabric in two weeks .

Which function has a zero with a multiplicity of 2?
Answer:p(x)=(x-1)(x-3)²
Step-by-step explanation:
The polynomial p(x)=(x-1)(x-3)² is a 3rd degree polynomial, but it has only 2 distinct zeros. This is because the zero x=3, which is related to the factor (x-3)², repeats twice. This is called multiplicity. It means that x=3 is a zero of multiplicity 2, and x=1 is a zero of multiplicity 1.

which equation represents a line that is perpendicular to the line on the graph?
A) y=-4x+3
B) y= -1/4x+1
C) y=-1/x-2
D) y= 4x+4
===================================================
Explanation:
The given visual line has a slope of -1/4. We can see this by starting at (0,2) and we do two things
a) move down 1
b) move over to the right 4
This leads to slope = rise/run = -1/4
Once we find the slope of the original line, we take the opposite reciprocal. This is also called the negative reciprocal. So we'll take the reciprocal of -1/4 to get -4/1 or just -4. Then we flip from negative to positive.
In short we flip the fraction and the sign. That has us go from -1/4 to 4.
The original slope is -1/4. The perpendicular slope is 4.
Side note: multiplying any two perpendicular slopes leads to -1. Neither line can be vertical.
--------------------------
So we found the slope of the perpendicular line to be m = 4.
We don't know which point the perpendicular line goes through, so theoretically we have infinitely many equations to pick from. They are all in the form y = 4x+b. Note how I replaced m in y = mx+b with 4.
So our answer will be in the form y = 4x+b. Choices A through C don't fit the description. Only choice D does. So choice D is the answer.
With y = 4x+4, the slope is 4 and the y intercept is 4.

Answer:5.656854
Step-by-step explanation:
A hockey player strikes a hockey puck. The height of the puck increases until it reaches a maximum height of 3 feet, 55 feet away from the player. The height $y$ (in feet) of a second hockey puck is modeled by $y=x\left(0.15-0.001x\right)$ , where $x$ is the horizontal distance (in feet). Compare the distances traveled by the hockey pucks before hitting the ground.
Answer:
Second puck travels farther
Step-by-step explanation:
Maximum height of first puck = 3 feet
The height of a second hockey puck is modeled by:
[tex]y=x\left(0.15-0.001x\right)[/tex]
[tex]y=0.15x-0.001x^2[/tex]
To find maximum height of second puck
[tex]y'=0.15-0.002x[/tex]
Equate the derivative equals to 0
0.15-0.002x=0
[tex]\frac{0.15}{0.002}=x[/tex]
75 = x
At x = 75
[tex]y=0.15(75)-0.001(75)^2=5.625[/tex]
So, The maximum height of second puck is greater than first puck
So, Second puck travels farther

Answer:
The answer is D: 42
Step-by-step explanation:
Angle 7 and angle 138 are supplementary and must add up to 180
Angle 7 is congruent to angle 6 through CPCTC (Corresponding Parts of Congruent Triangles are Congruent)
Angle 7 and 6 are corresponding angles
you must find angle 7 becasue Angle 7= Angle 6
angle 7=x
138-x=180
solve for equation you get
x=42
Angle 7 = 42
so that means that Angle 6 is 42

The volume of a right cylinder is 155.4 ft.3. The radius is
3 ft. Determine the height of the cylinder.
h=16.5ft.
h=17.3ft.
h=127.2ft.
h=5.5ft.
Answer:
5.499 = h likely if you used a better value for pi, it would be 5.5 = h
Step-by-step explanation:
Givens
V = 155.4
r = 3
pi = 3.14
Formula
V = pi*r^2*h Solve for h
Solution
155.4 = 3.14 * 3^2 * h 3^2 = 9
155.4 = 3.14 * 9 * h Combine the right
155.4 = 28.26 * h Divide by 28.26
155.4/28.26 = 28.26*h/28.26
5.499 = h
By first identifying the critical points of this function by determining the first derivative, and then calculating the second derivative at the crucial points, you may determine the volume's maximum. The critical point is a maximum if the second derivative is negative.
What determine height H of the cylinder, the height h cone?When a cone and cylinder have comparable heights, the cylinder's volume is three times greater than a cone's volume. Determine the cone's volume. To the tenth of a cubic centimetre nearest, round.
Therefore, a cylinder with the same base radius and height has a volume that is equal to one-third that of a cone.Learn more about cylinder.
