-2 the other person is also definitely right.

Answer:

D

Step-by-step explanation:

Slope = y2-y1/x2-x1

(7,-8) = (x1,y1)

(-5,-7) = (x2,y2)

Slope = (-7+8)/(-5-7)

          = 1/-12

Answer:

(-10,-2)

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

I did this by graphing the points on paper and then forming an equation from there. Another way is to do to slope equation. The slope equation is: [tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex], so you would just fill it in here. (4+4) (I did PLUS since subtracting a negative is adding a postive number). This equals 8. (0-2) is -2, so 8/-2 is -4x. For the y-intercept, it is already shown in the equation. This is 4 because if x is 0, then that is the y-intercept. So: y=-4x+4.

Answer:

x= -1

Step-by-step explanation:

p= x² +4x -2 -----(1)

q= 2x -1 ------(2)

q -p= 2 -----(3)

Substitute (1) and (2) into (3):

2x -1 -(x² +4x -2)= 2

2x -1 -x² -4x +2= 2 (Expand bracket)

-x² -2x +1=2 (Simplify)

x² +2x +2 -1= 0 (Bring all terms to one side)

x² +2x +1= 0

(x +1)²= 0 (Factorise)

x +1= 0 (Square root both sides)

x= -1 (-1 on both sides)

Step-by-step explanation:

Answer:

Q.1 area of triangle =1/2×base×height

area oftriangle=1/2×21 feet×16 feet

area of triangle =168feet²

Q.2 A=1/2×base×height

Q.3 area of triangle =1/2× base×height

35feet² =1/2×10feet× h

35 feet² =5 feet×h

35feet²/5 feet = h

7feet = h

Q.4 area of triangle =1/2×base×height

area of triangle =1/2×32×22

area of triangle =352 feet²

Answer:

X=0,-2

Step-by-step explanation:

6 x ( x + 2 ) = 0 Divide each term in 6 x ( x + 2 ) = 0 by 6 . 6 x ( x + 2 ) 6 = 0 6 Cancel the common factor of 6 .  x ( x + 2 ) = 0 6 Divide 0 by 6 . x ( x + 2 ) = 0 If any individual factor on the left side of the equation is equal to 0 , the entire expression will be equal to 0 . x = 0 x + 2 = 0 Set the first factor equal to 0 . x = 0 Set the next factor equal to 0 and solve. Tap for more steps... x = − 2 The final solution is all the values that make 6 x ( x + 2 ) 6 = 0 6 true. x = 0 , − 2

Answer:

$35,100

Step-by-step explanation:

Given data

Principal=$10000

Rate= 8.5%

Time = 15 years = 180 months

The expression for monthly compounded interest is

A=P(1+r/12)^t

substitute

A=10000(1+0.085/12)^180

A=10000(1+0.007)^180

A=10000(1.007)^180

A=10000*3.51

A=$35,100

Hence the balance is $35,100

Answer:

[tex]c = 11[/tex]

Step-by-step explanation:

Given

Let the three sides be a, b and c

Such that:

[tex]a = b= 5[/tex]

Required

Find c such that a, b and c do not form a triangle

To do this, we make use of the following triangle inequality theorem

[tex]a + b > c[/tex]

[tex]a + c > b[/tex]

[tex]b + c > a[/tex]

To get a valid triangle, the above inequalities must be true.

To get an invalid triangle, at least one must not be true.

Substitute: [tex]a = b= 5[/tex]

[tex]5 + 5 > c[/tex] [tex]===>[/tex] [tex]10 > c[/tex]

[tex]5 + c > 5[/tex]  [tex]===>[/tex] [tex]c > 5 - 5[/tex] [tex]===>[/tex] [tex]c > 0[/tex]

[tex]5 + c > 5[/tex]  [tex]===>[/tex] [tex]c > 5 - 5[/tex] [tex]===>[/tex] [tex]c > 0[/tex]

The results of the inequality is: [tex]10 > c[/tex] and [tex]c > 0[/tex]

Rewrite as: [tex]c > 0[/tex] and [tex]c < 10[/tex]

[tex]0 < c < 10[/tex]

This means that, the values of c that make a valid triangle are 1 to 9 (inclusive)

Any value outside this range, cannot form a triangle

So, we can say:

[tex]c = 11[/tex], since no options are given

Given:

The triangle A'B'C' is the image of triangle ABC after a translation as shown in the given graph.

To find:

The rule of translation in ARROW NOTATION.

Solution:

The general rule for translation is:

[tex](x,y)\to (x+a,y+b)[/tex]        ...(i)

Where, a and b are constants.

From the given graph it is clear that the coordinate of point A are (2,3) and coordinates of point A' are (4,-2).

Using (i), the image of A(2,3) is

[tex]A(2,3)\to A'(2+a,3+b)[/tex]

We have, A'(4,-2).

[tex]A'(2+a,3+b)=A'(4,-2)[/tex]

On comparing both sides, we get

[tex]2+a=4[/tex]

[tex]a=4-2[/tex]

[tex]a=2[/tex]

And,

[tex]3+b=-2[/tex]

[tex]b=-2-3[/tex]

[tex]b=-5[/tex]

Putting [tex]a=2[/tex] and [tex]b=-5[/tex] in (i), we get

[tex](x,y)\to (x+2,y+(-5))[/tex]

[tex](x,y)\to (x+2,y-5)[/tex]

Therefore, the rule in ARROW NOTATION for the given translation is [tex](x,y)\to (x+2,y-5)[/tex].

Answer:

x = 22°

the angles are: 63° and 117°

Step-by-step explanation:

a linear pair of angles total together to be 180°

so:

3x - 3 + 5x + 7 = 180

combune like terms:

8x = 176

divide both sides of the equation by 8:

x = 22°

the angles are: 63° and 117°
