Answer:

The zero of the function on the range (-0.7,-2.7) is {-2}

Step-by-step explanation:

The zeros of a function can be determined graphically and are the points where the graph intercepts the x-axis, that is, where the value of y is zero.

In this case we can see that the three points where the graph cuts to the x-axis are {-2,1,4}.

However if we evaluate the zeros of the function in the range writen on your question, the zero of the function in the range (-0.7, -2.7) would be only the number {-2}

Answer:

x ∈ {-2, 1, 4}

Step-by-step explanation:

The graph shows y = 0 when x = -2 or 1 or 4. Hence these values of x are the zeros of the function.

Given: RS = 3x - 16 ST = 4x - 8 RT = 60 Solve for RS.

Leno4ka [110]

RT = RS + ST
60 = 3x -16 + 4x -8
60 = 7x - 24
84 = 7x
84/7 = 7x/7
12 = x

RS = 3x - 16
RS = 3(12) - 16
RS = 36 - 16
RS = 20

Answer:

4x-20

Step-by-step explanation:

you put the x's together and since its negative,you can make it -20 instead of +-20

The graph shows two lines, A and B. A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line

maxonik [38]

there will be one solution because the lines intersect at exactly one set of points.

(0,6)(6,3)
slope(m) = (3-6) / (6-0) = -3/6 = -1/2

y = mx + b
6 = -1/2(0) + b
6 = b
y = -1/2x + 6

(0,0)(6,6)
slope(m) = (6-0) / (6-0) = 6/6 = 1

y = mx + b
6 = 1(6) + b
6 = 6 + b
6 - 6 = b
0 = b

y = x + 0

x = -1/2x + 6
1/2x + x = 6
1/2x + 2/2x = 6
3/2x = 6
x = 6/(3/2)
x = 6 * 2/3
x = 12/3 = 4

solution is : (4,4)

Use slopes and y-intercepts to determine if the lines 10x+3y=−3 and 5x−4y=−3 are parallel.

kvasek [131]

Answer:

They are not parallel

Step-by-step explanation:

original equation

10x + 3y = -3

subtract 10x

3y = -10x - 3

divide by 3

y = -10/3x - 1

original equation

5x - 4y = -3

subtract 5x

-4y = -5x-3

divide by -4

y = 5/4x + 3/4

the slopes are not equal to each other (5/4x and -10/3x) so they are not parallel
