Option B is correct.

I'm sure (-3 , 4)

Answer:

x=-3, y=4. (-3, 4). B)

Step-by-step explanation:

7x+2y=-13

-3x-8y=-23

-------------------

4(7x+2y)=4(-13)

-3x-8y=-23

---------------------

28x+8y=-52

-3x-8y=-23

-------------------

25x=-75

x=-75/25

x=-3

7(-3)+2y=-13

-21+2y=-13

2y=-13-(-21)

2y=-13+21

2y=8

y=8/2

y=4

Answer:

8

Step-by-step explanation:

Let x be the number of people

12.5x + 13 < 125

x < 8.96

Max number of x is 8

Answer:

See Explanation

Step-by-step explanation:

Let us assume that [tex] 5\sqrt 7[/tex] is a rational.

Therefore, it can be expressed in the form of [tex] \frac{p}{q}[/tex], where p and q are integers.

[tex] \implies 5\sqrt 7=\frac{p}{q}[/tex]

[tex] \implies \sqrt 7=\frac{p}{5q}[/tex]

[tex] \because [/tex] p and q are integers.

[tex] \therefore \frac{p}{5q}[/tex] is a rational number.

[tex] \implies \sqrt 7[/tex] is rational ([tex] \because [/tex] quotient of a rational number is rational)

But, it contradicts the fact that [tex]\sqrt 7[/tex]is irrational.

So, [tex]5\sqrt 7[/tex] is also irrational, because the product of rational and irrational is irrational.

This contradiction is arising out because of our wrong assumption that [tex] 5\sqrt 7[/tex] is rational.

Hence, [tex] 5\sqrt 7[/tex] is irrational.

Answer:

(-10, 10) or (-10, -10)

Step-by-step explanation:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex]

[tex]15 = \sqrt{(-10 - 1)^2 + (y_2 -2 )^2}[/tex]

[tex]15 = \sqrt{121 + 2y + y^2 + 4}[/tex]

[tex](15)^{2} =( \sqrt{121 + 2y + y^2 + 4})^{2}[/tex]

[tex]225 = 121 + 2y + y^2 + 4[/tex]

[tex]225 = 125 + 2y + y^2[/tex]

[tex]0 = -100 + 2y + y^2[/tex]

[tex]0 = (y + 10)(y - 10)[/tex]

Answer:

27.5

Step-by-step explanation:

70(0.80)^10 + 20 = 27.51619276 which s about 27.5

Answer:

x = 154°

Step-by-step explanation:

The central angle and the angle between the tangents are supplementary, so

x + 26° = 180° ( subtract 26° from both sides )

x = 154°

Step-by-step explanation:

find the area as if it was a rectangle so do 14x12 then subtract the area of half a circle with a diamater of 12

Answer:

4

Step-by-step explanation:

2x+y=12

y=-2x+12

y-2=3(x-2)

If it’s parallel to each other: the slope has to be the same.

If is perpendicular to each other: the slope should be the reciprocal to each other.

The first equation has a slope of -2

The second has a slope of 3

Neither the condition meet. So the answer is 4

Answer:

R = 90

Step-by-step explanation:

Triangles will always equal 180 degrees. If you add 61 + 29 = 90. If two of the three angles already equal 90 degrees, then you would subtract 180 - 90. Therefore, the remaining angle would have to be 90 degrees.

Answer:

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size.

The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

Step-by-step explanation:

so I will that they are similar

Answer:

Frontal lobe: The part of each hemisphere of the brain located behind the forehead that serves to regulate and mediate the higher intellectual functions. The frontal lobes are important for controlling thoughts, reasoning, and behaviors.

the lobe of the brain located closest to the ear. Structures in the temporal lobe are important for memory, language, and hearing, along with many other functions.

The primary visual cortex is located here and thus the occipital lobe is considered the visual center of the brain.

The parietal lobe is one of the major lobes in the brain, roughly located at the upper back area in the skull. It processes sensory information it receives from the outside world, mainly relating to touch, taste, and temperature.

Distance Formula:

The distance between two points is the length of the path connecting them. The shortest path distance is a straight line. In a 2 dimensional plane, the distance between points (X1, Y1) and (X2, Y2) is given by the Pythagorean theorem:

d=(x2−x1)2+(y2−y1)2−−−−−−−−−−−−−−−−−−√

Calculate Distance

To calculate the distance between 2 points, (X1, Y1) and (X2, Y2), for example, (5, 6) and (-7,11), we plug our values into the distance formula:

d=(−7−5)2+(11−6)2−−−−−−−−−−−−−−−−−√

combining terms inside parentheses we get:

d=(−12)2+(5)2−−−−−−−−−−−√

squaring both terms we get,

d=144+25−−−−−−−√

adding the 2 results,

d=169−−−√

finally,

d=13

Answer:

y = 3x - 25

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

Eliminate y by setting the first equation equal to the second:

2x - 7 = -x + 5

Combining like terms, we get:

3x = 12, so that x must be 4.
