When reflected over the x-axis and then dilated by a scale factor of 2 the points become (0,8), (-4,8), (-2,14) and (2,14). We need to know about reflection about axes and dilation.

When a point is reflected about the x-axis the x-coordinate remains same but the sign of the y-coordinate changes.When a point is reflected about the y-axis the sign of the x-coordinate changes while the y-coordinate remains same.When a point is reflected about the origin the sign of both the x-coordinate and the y-coordinate changes. Dilating a figure means changing it's shape or size by a scaling factor, the points are multiplied by the corresponding scaling factor. In this question we have to reflect the points about x-axis and dilate by a scale factor of 2. When the points will be reflected about the x-axis the new points will be (0,4) , (-2,4) , (-1,7) and (1,7). Then we have to dilate by a factor of 2, the final points will be (0,8), (-4,8) ,(-2,14) and (2,14).

After reflecting over x-axis and then dilating by a scale factor of 2 the points (0,-4), (-2,-4), (-1,-7) and (1,-7) become (0,8), (-4,8), (-2,14) and (2,14).

Hello!

[tex]\large\boxed{y = 5(\frac{1}{2})^{x} }[/tex]

Recall that the equation of an exponential graph is:

[tex]y = a(b)^{x}[/tex]

We can see from the graph there is a y-intercept at y = 5. Plugging in 0 for x results in:

[tex]5 = a(b)^{0}\\\\5 = a(1)\\\\a = 5[/tex]

Solve for b by plugging in another point on the graph:

[tex]10 = 5(b)^{-1}\\\\2 = b^{-1}\\\\b = 1/2[/tex]

Write the final equation:

[tex]y = 5(\frac{1}{2})^{x}[/tex]

the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.

x+(2x+15)+the measure of angle Q should equal 180.

Since everything is addition, the parenthesis can be removed.

x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.

Unfortunately I don't really know what to do from here, but I hope it helped at least a little.

Step-by-step explanation:

The subtraction property of equality is the property of equality that validates the statement "If VR + TY = EN + TY, then VR = EN." This assertion is expressed in the form of "If VR + TY = EN + TY, then VR = EN."

VR + TY = EN + TY

Therefore

VR=EN

The following equation results from using the equality property's subtraction property.

Thus, we have

VR + TY - TY = EN + TY - TY

Determine the difference in the aforementioned equation.

Thus, we have

VR = EN

Hence, If VR + TY = EN + TY, then VR = EN is supported by the equality's subtraction feature, which is stated as "If VR + TY = EN + TY, then VR = EN."

Answer:

First, make sure each equation is in slope-intercept form, where m is your slope and b is your y-intercept (y=mx+b). Next, starting from your y=intercept, graph the slope for each equation.

The goal of graphing the two lines is to find the point where both lines intersect (meet).

The solutions to each of the given algebraic expressions when a=2, b = -3, c=4 and d= -5a are as follows;

a) a + 2b = -4

b) bd - 10 = -25

c)  4b + 2a = -8

d) ab + cd = -26

e) cd² + ab = 94

f) d/2 - a = -9/2

g) bc/ad = 6/5

We are given the values a = 2, b = -3, c = 4 and d = -5.

a) a + 2b

Plug in 2 for a and -3 for b to get;

2 + 2(-3) = -4

b) bd - 10

Plug in b = -3 and d = -5 to get;

(-3 * -5) - 10 = -25

c)  4b + 2a

Plug in a = 2, b = -3 to get;

4(-3) + 2(2) = -12 + 4 = -8

d) ab + cd

Plug in a = 2, b = -3, c = 4, d= -5 to get;

(2 * -3) + (4 * -5) = -26

e) cd² + ab

Plug in a = 2, b = -3, c = 4, d= -5 to get;

(4 * (-5)²) + (2 * -3) = 94

f) d/2 - a

Plug in a=2 and d= -5 to get;

(-5/2) - 2 = -9/2

g) bc/ad

Plug in a=2, b = -3, c=4 and d= -5 to get;

Answer:

x-int: (-40, 0)

y-int: (0, 15)

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

According to the line on the graph, it passes the x-axis at x = -40 and it passes the y-axis at y = 15.

Therefore, our x-int is (-40, 0) and our y-int is (0, 15)

Answer:

Vertical line: x = -6

Horizontal line y = -2

Step-by-step explanation:

A vertical line will have a constant x value for all values of y so it will be of the form x = k where k is a constant. Since it passes through (-6,-2), where the x value is -6, we get the equation x = -6

A horizontal line will have a constant y value for all values of x so it will be of the form y = k where k is a constant. Since it passes through (-6,-2), where the y value is -2, we get the equation y = -2

The attached graph shows the two lines and the point (-6, -2)

Answer:

8 minutes

Step-by-step explanation:

If it takes 12 birds to eat 12 packets of food in 6 minutes that means it takes .5 minutes for 1 bird to eat 1 packet of food. 6÷12=.5

If there is 9 birds to eat 36 packets you first have to multiply the amount of birds times the rate it takes one to eat one packet. 9×.5=4.5 and with this now you know how many packets of food the group of 9 birds can eat per minute. Finally you divide the amount of packets by the amount of packets of food the group of 9 birds can eat per minute. 36÷4.5=8 And that's how they take 8 minutes to eat the 36 packets of food.

Correct answer is B. the probability that the total of the two dice will add up to 7 or 11 is 8/36

Suppose two dice are tossed

That means n(s)= 6×6 =36

Let E=Addition of number is 7 or 11

Probability of getting 7 is

N(E)= {(4,3),(3,4),(5,2),(2,5)(6,1)(1,6)}

Probability of get 11 is

{(6,5)(5,6)}

Total probability is 8

E=8

S=36

P(E)=n(E)/n(S)

The graph that could represent the relationship between distance and time is: Graph C.

A graph is usually plotted to have the independent variable on the x-axis and the dependent variable on the y-axis. For example, tin the scenario given, distance is plotted on the y-axis, while time is plotted on the x-axis.

The slope of a graph declines if the initial value decreases or if the slope value is negative and reduces.

In this scenario given, the starting value/initial value is 160 meters. After 3 seconds of driving, the initial value/starting value decreases to 85 meters.

This implies that the slope of the graph is declining from left to right. Therefore, the graph that could represent the relationship between distance and time is: Graph C.
