Solve The System By Solution

Answers

Answer:

(-8,-5)

Step-by-step explanation:

Answer:

-5x+y=35x-2y=2

Rewrite it, {-5x+y=2, 3x-2y=2}

Multiply both sides of the first equation by 2, {-10x+2y=4, 3x-2y=2}

Eliminate a variable, -7x=6

Divide both sides by -7, x=-6/7

Substitute the value of x, 3(-6/7)-2y=2

Possible solution, y=-16/7

Now to check the solution, (x, y)=(-6/7, -16/7)

Simplify, -5(-6/7)-16/7=3(-6/7)-2(-16/7)=2

The ordered pair, 2=2=2

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​

Answers

Answer:  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.

y = 2.2 + 5

D- 42

It needs to equal 180, and 180-138 is 42

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

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?

Answers

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

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.

Answers

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.

Which function has a zero with a multiplicity of 2?

Answers

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.

I think the answer would be -1/2 or D.

Step-by-step explanation:

Use this formula for calculating slope : y2-y1 / x2 - x1                                                            

1. label the pairs, 1 and 2

(-6, 1)  - ( x1, y1 )          or        (4,-4) - (x1, y1)

(4,-4) - ( x2, y2)                      (-6,1) - (x2, y2)  

(the order does not matter)

2. Than plug in your numbers

y2-y1 / x2 -x1                 y2-y1 / x2 -x1

-4 - 1 / 4 - (-6)        or        1 - (-4) / -6 - 4

= -5/10 or -1/2               = - 5/-10 or -1/2
