simplify the equation ✓52-✓117+4✓13​

Answer:

-.32

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The relantionship is perpendicular, because when you do the procedure that the question talks about, you find a circumference, and A and B are points of that cirumference.

As the segment is her diameter, we know that they, the points A and B, are perpendicular to the segment.

Why?

Because the definition of a circumference is:

> A single point in a bidimensional space that has the same distance from a infinity amount of points - remember that a point has no dimension, so there is infinity points over one point -, what became to be a circumference.

Also, take note that the lower distance for any point is a straight segment, who is perpendicular for both points.

But talk maybe do not help. Look the annex.

Answer:

600-700

Step-by-step explanation:

Given:

Speed of train = 85 miles per hour

Total distance = 102 miles

To find:

The time taken by train to cover 102 miles.

Solution:

We know that,

[tex]Speed=\dfrac{Distance}{Time}[/tex]

On substituting the values, we get

[tex]85=\dfrac{102}{Time}[/tex]

[tex]Time=\dfrac{102}{85}[/tex]

[tex]Time=1.2[/tex]

Therefore, the time taken by train to cover 102 miles is 1.2 hours.

Answer:

it would take 20 months and it would cost $6450

Step-by-step explanation:

in order to solve this question we need to equate the amount at each dealer against one another

make the months as an unknown variable (x)

2450 + 200x = 2950 + 175x

now make x the subject of formula

200x - 175x = 2950 - 2450

25x = 500

x = 500/25

x = 20

the amount would be the same in 20 months

replace x with 20

2450 + 200 (20) = 6450

$6450

Answer:

26$ because 13+13 is 26 boom

Answer:c

Step-by-step explanation:

Answer:

(1,2) and slope = 0

Step-by-step explanation:

Look where the line crosses the y and because the line is parallel to the x the slope is equal to zero

Answer:

(3, 6)

Step-by-step explanation:

If you create a mini graph, like I did, you would have seen that the middle point is at the co-ordinates (3,6). I have attached a image to this reply, with my "graph". (Sorry if its a little ugly, but that doesn't matter, the math does.)

Answer:

1) 7/12 is rational

2) √28 is irrational

3) √13/25 is irrational

4)  -15 is irrational

5) 5π is irrational

Answer:

x > -3, x >7

Step-by-step explanation:

for -2x < 6:

first divide each side by 2: -x < 3

then divide each side by -1, so the final answer is: x > -3

(whenever you divide by a negative number you have to flip the sign)

for 4x-7>21:

first, add 7 to each side: 4x>28

then divide each side by 4, and the final answer is: x >7

Answer:

Answer:

Valeria should use the reward worth $2 off her next purchase.

Step-by-step explanation:

To find the answer, you have to determine what Valeria would pay with each discount:

-reward worth $2 off her next purchase:

$7.50-$2=$5.50

-Save 15% coupon:

$7.50*0.15=$1.125

$7.50-$1.125=$6.375

According to this, the answer is that Valeria should use the reward worth $2 off her next purchase as she will pay $5.50 and with the save 15% coupon she would have to pay $6.375.

Answer:

The expression  -10 - (-4) represents the given diagram.

Step-by-step explanation:

Here, the total number of blue boxes marked with (-) = 10

So, in Total number of (-) are 10 x (-1) = -10

Now, the number of boxes crossed out = 4

So, the total value crossed out = 4 x ( Value on each box) = 4 ( -1) = -4

⇒ The value Left after crossing  = Total value - The crossed out value

                                                       = -10 - (-4)

Hence, the expression  -10 - (-4) represents the given diagram.

Answer:

Step-by-step explanation:

yes you can

the form of the equation is y=mx+b

the y intercept (0,b) when x=0 the y=b

and if you know the slope m, then you can form the equation

example : m=3 , and y intercept is (0,1)

y=mx+b

y=3x+b ( at point (0,1)

1=3(0)+b

b=1

the equation is y=3x+1

Answer:

the answer is 4

Answer:

x=5±√2

Step-by-step explanation:

x^2-10x=-23

x^2-10x+25=-23+25

(x-5)^2=2

x-5=±√2

x=5±√2

Answer: can you write the question??????!!!

Answer:

ok i know this is correct %100 it is D

Step-by-step explanation:

this is because if u have 8/20 and reduce by four do divide 8 by four and 20 by four that would be 2/5!!

IF THIS HELPED PLZ GIVE ME BRAINIEST!!

Answer:

2 / 5

Step-by-step explanation:

8/20 simplifies to 2/5. Simply divide 8 and 20 by 4 and you get your simplified fraction.

Answer:

(-1)(-3)

Step-by-step explanation:

i think u multiply them i hope thats right srry if its not

Answer: 35° and 55°

Step-by-step explanation:

For complementary angle, their total value equals to 90°.

Let the measure of the angle be y.

Therefore the complement will be:

= 90° - y

The measure of an angle plus twice its complement is equal to 145 can be expressed as:

y + 2(90 - y) = 145

y + 180 - 2y = 145

y = 180 - 145

y = 35°

The angle is 35° and its complement will be:

= 90 - y

= 90 - 35

= 55°

Answer:

6.25 km

Step-by-step explanation:

Let the number of km represented by 5 cm be x

Hence,

4 : 5 : : 5 : x

4x=25

x=6.25 km

Answer:

I dont understand the equation

Answer:

2 -5

Step-by-step explanation:

The slope and y-intercept are 2 and -5 after comparing them with the standard equation.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that:

The inequality is y > 2x-5

The above inequality represents the linear graph

After drawing on the graph:

On comparing:

y = mx + c

The slope m = 2

The y-intercept c = -5

Thus, the slope and y-intercept are 2 and -5 after comparing them with the standard equation.
