Answer:

C, y=-2/3x+1

Step-by-step explanation:

using points (0, 1) and (3, -1) obtained from the graph:

slope = -1-1/3-0 = -2/3

use one of the points above lets take (1, 0) and another point (x,y)

slope = y-0/x-1 = -2/3

y=-2/3x+1

Answer:

S8 is 64

Step-by-step explanation:

[tex]{ \boxed{ \bf{S_{n} = \frac{n}{2} [2a + (n - 1)d]}}}[/tex]

n is number of terms; n = 8

a is the first term; a = 1

d is the common difference: d = 3-1; d = 2

[tex]{ \sf{S_{8} = \frac{8}{2}[(2 \times 1) + (8 - 1) \times 2 ]}} \\ \\ { \sf{{S_{8}} = 4(2 + 14)}} \\ { \sf{S_{8}}} = 4 \times 16 \\ { \sf{S_{8}}} = 64[/tex]

they need to know what the Total

Answer:

English; 12

French; 9

Both; 7

Step-by-step explanation:

28 - 19 = 9, therefore there are only 9 students who can only speak French

28 - 16 = 12, therefore there are only 12 students who can only speak English

12 + 9 = 21, then subtract 21 from the 28 total students

28 - 21 = 7, therefore there are only 7 students who can speak both

Answer:

C. 70°

Step-by-step explanation:

but c = 180° - (2×20°) = 140°

b = 180° - c

b = 180° - 140° = 40°

[tex]{ \sf{a = \frac{1}{2}c }} \\ { \sf{a = ( \frac{1}{2} \times 140 \degree)}} \\ { \sf{a = 70 \degree}}[/tex]

The choose C. –1.5

Answer:

Step-by-step explanation:

When looking for extremes, one must consider both the turning points and the ends of the interval. Here, there is a relative minimum at x=7, and a relative maximum at x=3. However, the values at the ends of the interval are more extreme than these.

The absolute minimum on the interval is 2 at x=0.

The absolute maximum on the interval is 10 at x=10.

Answer:

x = 2.56, y = -2.63

Step-by-step explanation:

I first multiplied the second equation by two, getting

4x-6y = 26

I then subtracted the equations

 4x+2y = 5

- 4x-6y = 26

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

      8y = -21

y = -2.63

with y solved, I plugged it into the second equation to get x:

2x-3(-2.63) = 13

2x+ 7.89 = 13

2x = 5.11

x = 2.56

I hope this helped! ;D

Answer:

150%

Step-by-step explanation:

is the correct answer

The regular polygon that has a rotation of 240 degrees to carry the polygon onto itself is an B. Octagon.

This refers to an eight-sided polygon that has eight angles and is used in geometry.

Hence, we can see that an octagon, can be rotated to 240 degrees and when this is done, it is able to carry itself which cannot be done by others as other polygons would need 360 degrees to carry themselves.

Answer:

11. Yes

12. No

Step-by-step explanation:

11. The x values only have 1 y value, so it makes it a function.

12. The x value 0 has 2 y values -4 and 4, therefore it is not a function, because in functions that x value can only have one y value,

The fence would be the perimeter of the shape.

Perimeter = 17 + 17 + 14 + 14 = 62 meters.

Multiply the price per meter by total meters:

25 x 62 = 1550

For fencing , we have to find the perimeter of rectangle.

[tex] \large\begin{gathered} {\underline{\boxed{ \rm {\red{Formula \: \: Using \: = \: 2 \: ( \: L + B \: )}}}}}\end{gathered}[/tex]

Perimeter of rectangle = 2 ( L + B )

Perimeter of rectangle = 2 ( 17 m + 14 m )

Perimeter of rectangle = 2 ( 31 m )

Perimeter of rectangle = 62 m.

Hence, the perimeter of rectangle is 62 m.

For Fencing Cost = perimeter × rate of fencing per metre

Fencing Cost = 62 × 25

Fencing cost = 1,550

Hence, the cost of fencing of a rectangular plot is 1,550

Its a binomial

If zeros be alpha and beta

[tex]\\ \sf\longmapsto \alpha+\beta=\dfrac{-b}{a}[/tex]

[tex]\\ \sf\longmapsto \alpha+\beta=\dfrac{-(-6)}{1}[/tex]

[tex]\\ \sf\longmapsto \alpha+\beta=6[/tex]

the sum of the factors of the trinomial [tex]x^2-6x+5[/tex] is -6

Given :

A trinomial [tex]x^2-6x+5[/tex]

The given trinomial is in the form of [tex]ax^2+bx+c[/tex]

Compare the given trinomial with standard form and write the value of a,b,c

a=1, b=-6 and c=5

Sum of the factors of the trinomial is [tex]\frac{b}{a} =-\frac{-6}{1} =-6[/tex]
