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: 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:

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:

Step-by-step explanation:

l = 10

b = 6

d = √ [tex]l^{2} + b^{2}[/tex]

d = √ [tex]10^{2} + 6^{2}[/tex]

= √ 100 + 36

= √ 136

= 11.66

5) 5π is irrational

Answer:

5x+4y = 52

Step-by-step explanation:

We can first write the equation in point slope form

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

y - 8 = -5/4 ( x-4)

Multiply each side by 4 to get rid of the fraction

4(y - 8) = 4*(-5/4) ( x-4)

4(y - 8) = -5 ( x-4)

Distribute

4y - 32 = -5x+20

We want the equation in the form

Ax + By = C

Add 5x to each side

5x+4y -32 = -5x+5x+20

Add 32 to each side

5x+4y -32+32 =32+20

5x+4y = 52

Answer:

x = 1

Step-by-step explanation:

2x-10-3=15 (given)

2x-13=15 (simplification)

2x=2 (addition property of equality)

x = 1 (division property of equality)

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:

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

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:

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:

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.
