Answer:

y= -1/2x+4

Step-by-step explanation:

slope = rise/run on the graph. the graph is going down, so it's negative. find where the line intersects the graph at a point and then count the squares up and over until it meets again. the line meets at (6,1), you count up one square and over 2 and it meets again. this gives you your rise/run = 1/2. the y intercept is where the line intersects the y axis. here the y intercept is 4 because the like goes through 4 at the y axis.

Answer:

Step-by-step explanation:

let angle p be x

x+27=56 degree (sum of two opposite interior angle is equal to the exterior angle formed)

x=56-27

x=29 degree

therefore p is 29 degree.

Answer:

Step-by-step explanation:

The roots of the quadratic equation below using the quadratic formula are option A. [-9 ± √105 ] / 6.

Given is a quadratic equation,

3x² + 9x - 2 = 0

Quadratic formula to find the roots of a general quadratic equation ax² + bx + c is,

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

Here a = 3, b = 9 and c = -2.

Substituting the values,

x = [-9 ± [tex]\sqrt{9^2-(4)(3)(-2)}[/tex] ] / (2 × 3)

  = [-9 ± [tex]\sqrt{81+24}[/tex] ] / 6

  =  [-9 ± √105 ] / 6

So the roots are [-9 ± √105 ] / 6.

radius =( (8+7)^2 + (7+1)^2 )^1/2 = 17 unit

Equation of the circle = (x + 7)^2 + (y+1)^2 = 17^2

                                   = (-15+7)^2 + (y+1)^2  = 17^2

Answer:

x = -4    y = -1

Step-by-step explanation:

x + 4y = -8

4y = -x - 8

y = -1/4x - 2

6x - 2(-1/4x - 2) = -22

6x + 1/2x + 4 = -22

13/2x + 4 = -22

13/2x = -26

x = -4

(-4) + 4y = -8

-4 + 4y = -8

4y = -4

y = -1

Answer:

x = -4 y = -1

Step-by-step explanation:

Solve for each variable by creating an equation and plugging it in to the other given equation.

- Equation to solve for x: x = -4y - 8

- Plug this equation into the other, solving for y so you have:

6(-4y-8)- 2y = -22 => -24y - 48 - 2y = -22 => -26y = 26 =>  y = -1

- Take this value and plug into the equation we created for x:

x = -4(-1) - 8 => x = 4 -8 => x = -4

- Check your work with given equation 6x -2y = 22:

6(-4) - 2(-1) = -22 => -24 +2 = -22 => -22 = -22

Answer:

-1/13

Step-by-step explanation:

The slope of a line is calculated as rise/run.

The rise is the difference in y-values, and the run is the difference in x values

slope= y₂ - y₁/x₂ - x₁

let (26 , 7) be (x , y) and (-39 , 12) be (x₂, y₂)

slope= (12 - 7)/ (-39 -26)

        = 5/-65

reduce the fraction to get -1/13

Answer:

76

Step-by-step explanation:

The median line in the middle of the box is at 76 (the number line is by 2's)

==================================================

Explanation:

The median is the vertical line inside the boxplot. This vertical line is at 76.

The median does not have to be at the exact midpoint of the box, as it could be much closer to one of the edges. All that matters is the median is between Q1 and Q3

Q1 = left edge of the box

Q3 = right edge of the box

The min and max are the tips of the left and right whiskers respectively. This is when there are no outlier island points to either side.

Answer:

1.70

Step-by-step explanation:

Logarithmic functions are the inverses of exponential functions. Hence, exponential functions can be expressed in logarithmic form whereas logarithmic function can be expressed in exponential form. Since log is a function, it is most correctly written as log.

Given that f(x) = log₁₀(x)

To find the value of f(50), we substitute x to be 50 in the logarithm function and solve:

f(50) = log₁₀(50)

f(50) = log₁₀(5 * 10) = log₁₀(5) + log₁₀(10)  

f(50) = 1 + log₁₀(5) = 1 + 0.70

f(50) = 1.70

Answer:

I estimate he hit 400 bats.

Step-by-step explanation:

I am going to set up a ratio to solve.

Joseph hits about 2 out of every 5 bats, and we want to find out the number of hits we had if he was up to bat 1,000 times.

[tex]\frac{2}{5} = \frac{x}{1000}[/tex]

Cross multiply to solve.

2(1000) = 5(x)

2000 = 5x

Divide by 5 on both sides.

X = 400

I estimate he hit 400 bats.

C) 80

Step-by-step explanation:

Answer:

28

Step-by-step explanation:

Answer:

DE ≈ 16.1, ∠E ≈ 60.3°, ∠D ≈ 29.7°

Step-by-step explanation:

use pythagorean theorem:

DE² = 8² + 14² => DE = √8² + 14² ≈ 16.1

use inverse tangent function:

∠E =  [tex]tan^{-1}[/tex](14/8) ≈ 60.3°

∠D =  [tex]tan^{-1}[/tex](8/14) ≈ 29.7°

Answers:

The "units" and "degrees" portions of the answers are likely to be left out.

===============================================

Explanation:

Since we have a right triangle, we can use the pythagorean theorem to find the hypotenuse DE

a^2+b^2 = c^2

c = sqrt(a^2+b^2)

c = sqrt(8^2+14^2)

c = 16.124515496597

c = 16.1 is the approximate length of side DE

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

We'll use the tangent ratio to find angle E

tan(angle) = opposite/adjacent

tan(E) = FD/FE

tan(E) = 14/8

E = arctan(14/8)

E = 60.2551187030578

E = 60.3 degrees

The notation arctan is the same as inverse tangent. You should have a [tex]\tan^{-1}[/tex] button on your calculator to help compute the inverse tangent.

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

We could use the tangent ratio to solve for angle D, by noting that

tan(D) = 8/14

or we could use the idea that D+E = 90 which solves to D = 90-E

D = 90-E

D = 90-60.3

D = 29.7 degrees

Note how arctan(8/14) = 29.74488 which rounds to 29.7

Answer:

y = 2x + 5

Step-by-step explanation:

We have two points,

(-2,1) and

(4,13)

from which we can find the slope, m, where

m = (13-1)/(4--2) = 12/6 = 2

take any of the two points to form the point-slope form

y-y1 = m(x-x1)

y-13 = 2 (x-4)

y = 2x - 8 + 13 =2x+5

Check:

when x = -2, y = 2(-2)+5 = 1 checks.

Answer:

6a+6b

Step-by-step explanation:

6(a+b)

Use the distributive property to multiply 6 by a+b.

6a+6b

Answer:

C.

Step-by-step explanation:

x is bisecting the baseline (cutting it in 2 halves of 6).

the third angle in the main overall triangle is 60 degrees.

remember, all angles in a triangle always add up to 180 degrees.

so, 180 - 60 - 60 = 60.

that means that all 3 angles are of equal size (60). and that means that all 3 sides must have the same length.

=> y = 12

and now using Pythagoras to calculate the height (x) of the triangle :

y² = x² + 6² (remember, this side is only half the baseline)

12² = x² + 6²

144 = x² + 36

x² = 108

x = sqrt(108) = sqrt(36×3) = 6×sqrt(3)

Answer:

An expression to represent the length of the side of the square with an area of 4x^2+12x+9 in terms of x is 2x + 3

Step-by-step explanation:

all sides of a square are equal in length.

area of a square is the side length squared.

area a, side s, variable x.

a = 4x^2 + 12x + 9.   s = ?   x = ?

a = s^2.

a = 4x^2 + 12x + 9.

4x^2 + 12x + 9 = s^2.

x^2 + 3x + 9/4 = (s^2)/4.

factor x^2 + 3x + 9/4 = (s^2)/4.

(x + 3/2)(x + 3/2) = (s^2)/4.

(x + 3/2)^2 = (s^2)/4.

√((x + 3/2)^2) = √((s^2)/4).

take positive root.

x + 3/2 = s/2

solve for side s.

s/2 = x + 3/2

s = 2x + 3
