Find the midpoint of the segment.

A. (4, 2)
B. (1, 0)
C. (-4, 0)
D. (0, 1)

Answer:

C (The lower left one)

Step-by-step explanation:

I saw that the vertex was equal to (-1,1) and that is the only answer that makes sense

The graph of the function y = x shifted 1 unit up and moved 1 unit to the left

so the new function is now y = (x + 1) + 1.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

By observing the figure we conclude that it shifted 1 unit up and moved 1 unit to the left.

If the original graph was y = x now it is y = (x + 1) + 1.

-3 is a constant.

Step-by-step explanation:

The given equation is :

4x+5y-3 ...(1)

The general equation is :

ax+by+c ...(2)

c is a constant

If we compare equations (1) and (2), we find that.

c=-3

Hence, the constant in this expression is -3.

Answer:

5.5

Step-by-step explanation:

Sales tax = tax rate × Cost of meal

Sales tax = $1.32

Tax rate = x%

Cost of meal = $24

Sales tax = tax rate × Cost of meal

1.32 = x% × 24

1.32 = x/100 × 24

1.32 = 24x/100

1.32 * 100 = 24x

132 = 24x

x = 132/24

x = 5.5%

= 5.5

Probability of an event is the measure of its chance of occurrence. The experimental probability of Janice rolling the number four is 0.2

Experimental probability calculates the probability of some event from the results of experiments.

For an event E, we get the experimental probability of that event

[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]

where, [tex]P_e(E)[/tex] is denoting experimental probability of occurrence of E.

For this case, we're specified that:

The event in consideration is "Rolling the number 4"

The times she rolled the number 4 is: 12

She got four 12 times in 60 rolls of the considered cube.

Thus, we have:

Thus, we get:

[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}} = \dfrac{12}{60} = \dfrac{1}{5} = 0.2[/tex]

Thus, the experimental probability of Janice rolling the number four is 0.2

Divide 188.88 by 7 to get the cost for each. The round to the nearest hundredth.

Answer and explanation:

Given the above, we find y in terms x

change in y change in x = 0.5

The formula for a straight line is y= mx+b where m is slope of the line and b is the y intercept

We substitute given values above in the straight line equation:

y=mx+b

1.5= 0.5×3+b

1.5=1.5+b

b= 0

y in terms of x for the line is therefore given by the formula :

y=0.5x+0

a = -24

Answer:

b) a = -10

Step-by-step explanation:

a + (-7) = -17

simplify

a - 7 = -17

add 7 to both sides of the equation

a - 7 + 7 = -17 + 7

a = -17 + 7

a = -10

Answer:

(-3,-1)

Step-by-step explanation:

6x-12y=-6

6x=12y-6

x=2y-1

9(2y-1)-6y= -21

18y-9-6y=-21

12y= -12

y=-1

6x-12(-1)=-6

6x+12= -6

6x=-18

x=-3

Answer:

x = -3 ; y = -1

Step-by-step explanation:

Let 9x - 6y = -21 be eqn.1 & let 6x - 12y = -6 be eqn.2 .

Lets find the value of x from eqn.1

[tex]9x - 6y= -21[/tex]

[tex]=> 3(3x - 2y) = -21[/tex]

[tex]=> 3x - 2y = \frac{-21}{3} = -7[/tex]

[tex]=> x = \frac{2y - 7}{3}[/tex]

Now , lets put the value of x (which we got from eqn.1) in eqn.2 :-

[tex]6x - 12y = -6[/tex]

[tex]=> 6(x - 2y) = -6[/tex]

[tex]=> x - 2y = \frac{-6}{6} = -1[/tex]

(Putting x here)

[tex]=> \frac{2y - 7}{3} - 2y = -1[/tex]

[tex]=> \frac{2y - 7 - 6x}{3} = - 1[/tex]

[tex]=> -4 y - 7 = -1 \times 3 = -3[/tex]

[tex]=> -4y = 7 - 3 = 4[/tex]

[tex]=> y = \frac{-4}{4} = -1[/tex]

Now , lets find the value of x.

[tex]x = \frac{2y - 7}{3}[/tex]

Putting y = -0.5 gives ,

[tex]x = \frac{[2 \times (-1)] - 7}{3}[/tex]

[tex]=> x = \frac{-2 - 7}{3} = \frac{-9}{3} = -3[/tex]

Answer:

Answer:

a) The y-intercept is 160. It represents the initial distance Jayden was from his home.

b) The x-intercept is 4. It represents the amount of time taken for Jayden to reach his home.

Step-by-step explanation:

The y-intercept can be found by looking at the value of y when x=0. When x=0, y= 160. Since the x-axis is the amount of time in hours, x=0 would mean the initial time. The x-axis is the number of miles from Jayden's home thus, Jayden was 160 miles away from his home when x=0 hours.

The x-intercept can be found by looking at the x value when y=0. When y=0, x=4. This means that it took Jayden 4 hours to reach home or 4 hours to travel 160miles to his house.
