Answer:

y = -½x + 4

Step-by-step explanation:

Equation of any line in slope-intercept form is y = mx + b, where,

m = slope = change in y/change in x

b = y-intercept = the point on the y-axis intercepted by the line.

Let's find m and b.

✔️Using two points on the line, (0, 4) and (2, 3),

Slope (m) = change in y/change in x = (3 - 4)/(2 - 0)

m = -1/2 = -½

✔️The line intercepts the y-axis at y = 4.

Therefore,

b = 4

✔️To write the equation of the line, substitute m = -½ and b = 4 into y = mx + b.

Thus,

y = -½x + 4

B

Answer:

Axis of Symmetry: [tex]x=5[/tex]

Step-by-step explanation:

The axis of symmetry is defined as the line [tex]x=\frac{-b}{2a}[/tex]. Therefore, our axis of symmetry is located at the line [tex]x=\frac{-(-10)}{2(1)}=\frac{10}{2}=5[/tex]. See the graph attached for a visual.

Answer:

x = 5

Step-by-step explanation:

That's f(x) = x^2 - 10x + 16.  The coefficients of the x terms are {1, -10, 16}:  {a, b, c}.  

                                                                         -b

The formula for the axis of symmetry is x = --------

                                                                           2a

Here, with a = 1 and b = -10, the formula for this particular axis of symmetry is

       -(-10)

x = ------------ = 5

         2(1)

or x = 5

Answer:

angle 1=117 because it have vertical angles of congruence theorem

angle 2= 117 because it has the alternate exterior angle theorem

hope this helps

have a good day :)

Step-by-step explanation:

vertical angles have the same length

alternate exterior angles would have the same angle measure because they are on opposite side of the angles

Answer:

68

Step-by-step explanation:

Total mile cycled, d(t) ;

d(t) = 12t + 20

At d(4)

t = 4 ;

We have;

d(4) = 12(4) + 20

d(4) = 48 + 20

d(4) = 68

After, 4 hours of cycling, Joanna cycled a total distance of 68 miles

Answer:

Step-by-step explanation:

It is an obtuse triangle because one angle (5) takes up more than the sum of the other two (3+1=4).

The angles are:

5+3+1 = 9

Each angles is

5/9 * 180 = 100°

3/9 * 180 = 60°

1/9  * 180 = 20°

Total = 100+60+20 = 180 degrees.

Answer:

x = 5

Step-by-step explanation:

Simplifying

6x + -3 = 3x + 12

Reorder the terms:

-3 + 6x = 3x + 12

Reorder the terms:

-3 + 6x = 12 + 3x

Solving

-3 + 6x = 12 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-3 + 6x + -3x = 12 + 3x + -3x

Combine like terms: 6x + -3x = 3x

-3 + 3x = 12 + 3x + -3x

Combine like terms: 3x + -3x = 0

-3 + 3x = 12 + 0

-3 + 3x = 12

Add '3' to each side of the equation.

-3 + 3 + 3x = 12 + 3

Combine like terms: -3 + 3 = 0

0 + 3x = 12 + 3

3x = 12 + 3

Combine like terms: 12 + 3 = 15

3x = 15

Divide each side by '3'.

x = 5

Answer:

[tex]\displaystyle \sin E=\frac{20}{101}[/tex]

Step-by-step explanation:

Recall that sine is the ratio between the opposite side and the hypotenuse in a right triangle:

[tex]\displaystyle \sin x=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]

In the given triangle, with respect to E, the adjacent side is 99, and the hypotenuse is 101. So, we are not given the value of the opposite side.

Since it is a right triangle, we can use the Pythagorean Theorem. Hence:

[tex]OU^2+99^2=101^2[/tex]

Solving for OU (the opposite side) yields:

[tex]OU=\sqrt{101^2-99^2}=20[/tex]

Therefore, the opposite side is 20.

Hence:

[tex]\displaystyle \sin E=\frac{20}{101}[/tex]

Answer:

I believe its c $1520 overall there's only a decrease of 5%

Answer:

The value of the investment on August 1st is $1,512.

Step-by-step explanation:

To find the value of the percentage decreased by the percent of its value, simply subtract a number to a percent. To find the value of the percentage increased by the percent of its value, add a number to the percent. In this case, the value of the investment started with $1,600 and then it decreased by 10%. We can write our equation like this: 1,600 - 10% = ?. Don't think about turning 10% into 0.1. You could do that, but it wouldn't result in the answer as the value decreased by 10%. It would turn out to be 1,599.9 if you did subtract 1,600 by 0.1. It is NOT the value DECREASED by 10%. I think some people would mistakenly go on to that path but please don't. You will NOT recieve an accurate answer. Following the equation, you should get $1,440. That is the investment made during the month of June decreased by 10%.

During the month of July, the value INCREASED by 5%. Similar to the percentage decreased equation, we just turn the subtraction symbol into an addition symbol. Do the same process again but with an addition symbol and the NOW value of $1,440. You should get $1,512 as your final answer. If you are confused about how I got this answer, look at this equation for percentage increased: 1,440 + 5% = ?. If I am wrong, please let me know and I hope this helps! :D

Answer:

I think the answer is B. 54

Answer:

D. 53

Step-by-step explanation:

"without the outlier"...the outlier is 91 because it is way higher than all the other number which are in the 50's. So you just find the mean of 51, 54, 55, and 52.

To do this, you add all the numbers together and divide by how many numbers there are.

51+54+55+52=212

212/4=53

The mean is 53

Answer:

Step-by-step explanation:

The general approach here is to choose a variable you want to eliminate, identify the coefficients of it, and use those to multiply the equations so adding the products will eliminate the variable.

Here, the coefficients of x are -1 and -3; the coefficients of y are 2 and 5. We often like to choose the set of coefficients that includes 1 or where the coefficients are related by an integer factor. These criteria suggest that we should use the coefficients -1 and -3. One of our multipliers must be the opposite of one of these coefficients. So, we choose for them to be -3 and +1.

That is, multiplying the first equation by -3 will make the x-coefficient be 3; multiplying the second equation by 1 will make the x-coefficient be -3. Adding these equations will then eliminate x terms.

  (-3)(-x +2y = 12)

+ (1)(-3x +5y =27)

gives (3x -6y) +(-3x +5y) = -36 +27

which simplifies to the sum ...

  0x -1y = -9

__

Dividing by the coefficient of y, we find y = 9. Substituting into the first equation, we have ...

  -x +2(9) = 12)

  x = 18-12 = 6

The solution is (x, y) = (6, 9).

Answer:

1st term = 14

2nd term = 29

3rd term = 44

Step-by-step explanation:

1st term = 3 x (5x 1) - 1

             = 3 x 5 - 1

             = 15 - 1 = 14

2nd term = 3 x ( 5 x 2 ) - 1

               = 3 x 10 - 1

                =30 - 1 = 29

3rd term = 3 x (5 x 3 ) - 1

               = 3 x 15 - 1

               = 45 - 1 = 44

Answer:

C. 39

Step-by-step explanation:

If AB = BC, and angle A is 39 degrees. we can assume that angle C would have a similar angle.

Since in △ABC , AB=BC

∴ the triangle is isoceles.

In an isoceles triangle the angles opposite to equal sides are equal.

∴∠A=∠C

This means that C.39 is the correct answer

Answer:

39, C

Step-by-step explanation:

If angle A = 39, then the angle C is equal to A. This may seem like a weird question, but it’s the way that the triangle is positioned.

Also, you can prove this by looking at the equation provided in the prompt.

B is the vertex that they are creating this problem from, therefore, it may be helpful to turn the triangle around!
