Charra [1.4K]

Answer:

there are 114

Step-by-step explanation:

Ratio of red marbles to black marbles is 19:1. (Data from 3rd sentence)

19+1= 20

20 units= 120 (Data from 1st sentence)

1 unit= 120/20= 6

19 units= 120-6= 114 (Values solved in working above)

Ans: There are 114 red marbles.

Graph the image of the given triangle after a rotation of 180º about the origin.
aleksandrvk [35]

Answer:

(1,-1) (5,-4) (-2,6)

Step-by-step explanation:

The triangle will be rotated to 180 degrees which means you need this formula to point all the corners of the triangle…

Formula:

(x,y) —> (-x,-y)

(-1,1) —> (1,-1)

(-5,4) —> (5,-4)

(-2,6) —> (2,-6)

Plot these point…

(1,-1) (5,-4) (-2,6)

What is the term a8 of the sequence {an} if an equalsa) 2n−1?b) 7?c) 1 + (−1)n?d) −(−2)n?
Degger [83]
The correct question in the attached figure

case A) an=2<span>^(n-1)
for n=8
a8=2</span>^(8-1)-----> a8=2<span>^7----> a8=128

the answer case A) is 
a8=128

case B) an=7
then for n=8
a8=7

the answer case B) is
a8=7

case C) an=1+(-1)</span><span>^n
for n=8
a8=1+(-1)</span><span>^8----> a8=1+1----> a8=2

the answer case C) is
a8=2

case D)an=-(-2)</span><span>^n
for n=8
a8=-(-2)</span><span>^8----> a8=-256

the answer case D) is
a8=-256</span>

Write the equation of the line perpendicular to 4x – 5y = -10 through the point (2, 3). explain please
Snezhnost [94]

Answer:

y =-5/4x +11/2

Step-by-step explanation:

First we need to find the slope of the line

4x-5y = 10

Solve for y

Subtract 4x from each side

4x-4x-5y =-4x-10

-5y = -4x-10

Divide by -5

-5y/-5 = -4x/-5 -10/-5

y = 4/5x +2

The slope is 4/5

The slope of a line that is perpendicular is the negative reciprocal

m perpendicular = - (5/4)

We know have a slope = -5/4 and a point (2,3)

We can use the point slope form of a line

y-y1 = m(x-x1)

y-3 = -5/4 (x-2)

Distribute

y-3 =-5/4x +10/4

Add 3 to each side

y-3+3 = -5/4 x +5/2 +3

Get a common denominator

y = -5/4x +5/2 +6/2

y =-5/4x +11/2
