solve this equation x-y=5
3x+y=3​

Answer: The answer is x=[tex]\frac{-3-\sqrt{65} }{4}[/tex], [tex]\frac{-3+\sqrt{65} }{4}[/tex]

Step-by-step explanation:

1) You can solve a situation like [tex]ax^2+bx+c=0[/tex] using the quadratic formula

[tex]x=-b[/tex]±[tex]\sqrt{b^2-4ac}[/tex] / 2a

2) Apply that to the problem and we get x= -3±[tex]\sqrt{3^2-4*2*(-7)}[/tex]/2*2

3) Solve what's inside the square root and what's at the denominator --> x=-3±[tex]\sqrt{65}[/tex]/4

4) separate the solutions ---> [tex]x=\frac{-3+\sqrt{65}}{4} , \frac{-3-\sqrt{65}}{4}[/tex]

5) Your final solutions are [tex]x=\frac{-3+\sqrt{65}}{4} , \frac{-3-\sqrt{65}}{4}[/tex]

Answer:

The total cost of the first full year of membership is $500.00.

Step-by-step explanation:

m = per month

x = total cost

Equation: 80 + 35m = x

Since there are 12 months in a year and we want to figure out how much it will cost for the first full year of membership, we will substitute variable m for 12.

80 + 35(12) = x

80 + 420 = 500

Answer:

A maximum of 4 days

Step-by-step explanation:

Inequality: 95 + 11.50x ≤ 150

Okay so the 95 is his fee. Then for everyday, it's 11.50 and we don't know how many days yet, so 11.50x. The 95 dollars and the 11.50x has to equal to or less than 150 since that is how much he has to spend on vaca.

95 + 11.50x ≤ 150

-95                   -95

11.50x ≤  55

/11.50       /11.50

X=4.78260869565

You would round down since he has a budget.

Answer:

36

Step-by-step explanation:

if we were decreasing it would be 9 but if we are increasing it, it would be 36

just multiply by 2 or divide by 2

Answer:

27

Step-by-step explanation:

increasing by 1 half is like dividing. 4 increased by one half would be 6, because half of four is 2, and you add that on to four. increasing 18 by half, divide 18 by 2, that = 9 then add 9 onto 18. the answer is 27

Answer:

(-2/7,2/3)

Step-by-step explanation:

Let's solve for x.

−7x+3y=2

Step 1: Add -3y to both sides.

−7x+3y+−3y=2+−3y

−7x=−3y+2

Step 2: Divide both sides by -7.

−7x/ −7 = −3y+2/ −7

x= 3/ 7 y+ −2/ 7

Answer:

x= 3/ 7 y+ −2/ 7

Let's solve for y.

−7x+3y=2

Step 1: Add 7x to both sides.

−7x+3y+7x=2+7x

3y=7x+2

Step 2: Divide both sides by 3.

3y/ 3 = 7x+2/ 3

y= 7/ 3 x+ 2/ 3

Answer:

y= 7/ 3 x+ 2/ 3

Answer:

y= -3/2X + 2

Step-by-step explanation:

we get the gradient by picking any two points from the graph( it a linear graph)

using the point:

(x,y)= (-2,5) , (4,-4)

using M= (y2-y1)/x2-x1)

we get our gradient to be -9/6 which is

-3/2

using the equation of a straight line graph which is

y-y1=m(x-x1) and the point (4,-4)

we get

y-(-4)=-3/2(x-4)

----> y+4= -3/2x + 6

make y subject of the formula to take the form

y=mx+c

we get :

y=-3/2x + 2

Step-by-step explanation:

Answer:

it stays the same so 178.572

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

(a)

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180° for B

∠ B = 180° - (90 + 63)° = 180° - 153° = 27°

(b)

Using the sine ratio in the right triangle

sin63° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{15}{x}[/tex] ( multiply both sides by x )

x × sin63° = 15 ( divide both sides by sin63° )

x = [tex]\frac{15}{sin63}[/tex] ≈ 16.8 ( to 1 dec. place )

(c)

Using the tangent ratio in the right triangle

tan63° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{15}{y}[/tex] ( multiply both sides by y )

y × tan63° = 15 ( divide both sides by tan63° )

y = [tex]\frac{15}{tan63}[/tex] ≈ 7.6 ( to 1 dec. place )

Given:

The figure of a circle.

To find:

The measure of arc AD and measure of each arc.

Solution:

The measure of arc is equal to the central angle of that arc.

The central angle of arc AD is 105 degrees. So,

[tex]m(arc(AD))=105^\circ[/tex]

The central angle of arc BC is 35 degrees. So,

[tex]m(arc(BC))=35^\circ[/tex]

The central angle of arc CD is 50 degrees. So,

[tex]m(arc(CD))=50^\circ[/tex]

The central angle of a complete circle is 360 degrees. So,

[tex]m(arc(AD))+m(arc(BC))+m(arc(CD))+m(arc(AB))=360^\circ[/tex]

[tex]105^\circ+35^\circ+50^\circ+m(arc(AB))=360^\circ[/tex]

[tex]190^\circ+m(arc(AB))=360^\circ[/tex]

[tex]m(arc(AB))=360^\circ-190^\circ[/tex]

[tex]m(arc(AB))=170^\circ[/tex]

Therefore, the measure of arc AD is 105°, the measure of arc BC is 35°, the measure of arc CD is 50° and the measure of arc AB is 170°

Answer:

x is 0.

9(0) - 7 = -7

Step-by-step explanation:

Answer: X=0

Step-by-step explanation:

Data: 9x-7=7

Step one, Add 7 to both sides

9x-7+7=-7+7=9x=0

The reason you do this is that your trying to isolate x so by adding 7, you get rid of the -7 right by 9x and since what you do to one side you do to the other, you add 7 to the other -7 as well to get 0

Step two, Divide by 9 on both sides

9x/9=0/9=x=0

The reason for this is that your trying to isolate x and by dividing by 9, you take out the 9 next to the x. However what you do to one side you have to do to the other so you divide 0 by 9 as well

Answer: X=0

Answer:

The area of the shaded region is 11.606 square centimeters.

Step-by-step explanation:

The area of the shaded region is obtained by subtracting the area of the triangle from the area of the circular section. The area of the triangle ([tex]A_{t}[/tex]), in square centimeters, can be calculated by the Heron's formula:

[tex]A_{t} = \sqrt{s\cdot (s-a)\cdot (s-b)\cdot (s-c)}[/tex] (1)

[tex]s = \frac{a + b + c}{2}[/tex] (2)

Where:

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Lengths of the sides of the triangle, in centimeters.

[tex]s[/tex] - Semiperimeter, in centimeters.

If we know that [tex]a = 10.50\,cm[/tex] and [tex]b = c = 9.28\,cm[/tex], then the area of the triangle is:

[tex]s = \frac{10.50\,cm + 2\cdot (9.28\,cm)}{2}[/tex]

[tex]s = 14.53\,cm[/tex]

[tex]A_{t} = \sqrt{(14.53\,cm)\cdot (14.53\,cm - 10.50\,cm)\cdot (14.53\,cm - 9.28\,cm)^{2}}[/tex]

[tex]A_{t} \approx 40.174\,cm^{2}[/tex]

And the area of the circular section ([tex]A_{c}[/tex]), in square centimeters, is determined by the following formula:

[tex]A_{c} = \left(\frac{\theta\cdot \pi}{360} \right)\cdot r^{2}[/tex] (3)

Where:

[tex]r[/tex] - Radius of the circle, in centimeters.

[tex]\theta[/tex] - Internal angle, in sexagesimal degrees.

If we know that [tex]r = 9.28\,cm[/tex] and [tex]\theta = 68.9^{\circ}[/tex], then the area of the circular section is:

[tex]A_{c} = \left(\frac{68.9}{360}\right)\cdot \pi\cdot (9.28\,cm)^{2}[/tex]

[tex]A_{c} \approx 51.780\,cm^{2}[/tex]

Finally, the area of the shaded region ([tex]A[/tex]), in square centimeters, is:

[tex]A = A_{c} - A_{t}[/tex] (4)

[tex]A = 51.780\,cm^{2}- 40.174\,cm^{2}[/tex]

[tex]A = 11.606\,cm^{2}[/tex]

The area of the shaded region is 11.606 square centimeters.

Answer:

0

Step-by-step explanation:

Use the formula y2-y1/x2-x1. The two points are (-2,4) and (3,4) This will make the equation 4-4/-2-3. This simplifies to 0/-5. This is equal to 0. Therefore, the slope is 0.

If this has helped you please mark as brainliest

The slope of the line that passes through these two points (-2, 4) and (3, 4) will be 0.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

Slope = Rise / Run

Slope = (y₂ - y₁) / (x₂ - x₁)

Then the slope of the line that passes through these two points (-2, 4) and (3, 4) will be

Slope = (4 - 4) / (3 - (-2))

Slope = 0 / 5

Slope = 0
