A. 8.5
B. 8.2
C. 13
D. 4

Answers

Answer:

B. 8.2

Step-by-step explanation:

[tex] In\: \triangle ABC, \:\angle ABC= 90\degree \: \&\: BD\perp AC[/tex]

So, by geometric mean property.

[tex] BD = \sqrt {AD\times CD} \\

BD = \sqrt {13\times 4}\\

BD = \sqrt {52}\\

Next\: in \: \triangle BDC, \:\\

By\: Pythagoras \: theorem \\

m^2 = BD^2 + CD^2 \\

m^2 = (\sqrt {52}) ^2 + (4)^2 \\

m^2 =52 + 16\\

m^2 =68\\

m =\sqrt{68} \\

m = 8.24621125\\

m = 8.2 [/tex]

A = Alonzo's age

Alonzo's age is:

Right triangle ABC is on a coordinate plane. Segment AB is on the line y = 2 and is 3 units long. Point C is on the line x = −1. If the area of ΔABC is 6 square units, then find a possible y-coordinate of point C.

A: 6
B: 7
C: 8

Answers

C:8 is the answer my guy welcome

Answer:

A.  6

Step-by-step explanation:

Segment AB is on the line y = 2 and is 3 units long.

Point C is on the line x = −1.

FIND:

If the area of ΔABC is 6 square units, then find a possible y-coordinate of point C.

SOLUTION:

Area of a triangle = 1/2 b * h

segment AB is a horizontal line

the base of our triangle and point C is somewhere on the height.

If we can find the height of the triangle, we can add or subtract that height from y = 2 to get the possible y coordinate of point C.

We know that the x coordinate is -1 so,

6 = 1/2 (3) h

12 = 3h

h = 4

we can either add 4 or subtract 4 to the y coordinate of 2 to get the possible y coordinate of point C.

option 1

2 + 4 = 6 so the coordinate for C could be (-1, 6) or

option 2

2 - 4 = -2 so the coordinate for C could also be (-1, -2).

Since -2 is not in our choices but 6.

therefore,

the answer would be A. 6

What two numbers have a product of -2 and a sum of 7

Answers

Greetings from Brasil...

According to the statement of the question, we can assemble the following system of equation:

X · Y = - 2      i

X + Y = 7       ii

isolating X from i and replacing in ii:

X · Y = - 2

X = - 2/Y

X + Y = 7

(- 2/Y) + Y = 7     multiplying everything by Y

(- 2Y/Y) + Y·Y = 7·Y

- 2 + Y² = 7X     rearranging everything

Y² - 7X - 2 = 0      2nd degree equation

Δ = b² - 4·a·c

Δ = (- 7)² - 4·1·(- 2)

Δ = 49 + 8

Δ = 57

X = (- b ± √Δ)/2a

X' = (- (- 7) ± √57)/2·1

X' = (7 + √57)/2

X' = (7 - √57)/2

So, the numbers are:

(7 + √57)/2

and

(7 - √57)/2

Amira is told there is a trick to finding the slope within an equation in standard form, Ax+By=C. She is told she can rewrite this equation in slope-intercept form, y=mx+b, to find the pattern. She correctly rewrites the equation 7x+9y=14 in slope-intercept form as y=− 7/9x +14/9. Which answer explains the pattern for how to find the slope using an equation in standard form?


A. In slope-intercept form, the slope is 14/9. These values are C and A, but with the opposite sign, so the slope of the line from the equation in standard form is − C/A.

B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

C. In slope-intercept form, the slope is 14/9. These values are C and B, but with the opposite sign, so the slope of the line from the equation in standard form is − C/B.

D. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − B/A.

Answers

Answer:

B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

Step-by-step explanation:

Let's convert the standard equation into slope-intercept form:

Ax + By = C              ⇒ subtract Ax from both sidesBy = -Ax + C             ⇒ divide both sides by By = -A/Bx + C/B        ⇒ converted to slope- intercept form

As we see the slope is -A/B

The equation 7x + 9y = 14 is converted as:

y = -7/9x + 14/9, where the slope is -7/9

Looking at the answer options and the correct one is option B, where both identification of slopes match.

B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

50 POINTS NOW!! Which inequality is equivalent to the given inequality plz help

Answers

-4(x + 7) < 3(x - 2)

Let's simplify this inequality

-4x - 28 < 3x - 6

Subtract 3x from both sides and add 28 to both sides

-7x < 22

Answer choice B is correct

Answer:

-7x < 22

Step-by-step explanation:

1. -4(x+7) < 3(x-2)

distribute -4 to x and 7, distribute 3 to x and -2.

2. -4x-28 < 3x-6

add 28 to 28 to cancel it out, add 28 to -6.

3. -4x < 3x+22

subtract 3x from 3x to cancel it out, subtract -3x from -4x.

4. -7x < 22

the final product! the answer is B. -7 < 22. since there was no multiplication or division, there's no need to switch < to >. hope this helps! :)
