I very easy solve for x> then you take -3 -2 1,0 in order to get your answer
Answer:
x = {-3, -2, -1, 0, 1}
Step-by-step explanation:
We need to find the set that satisfies the inequality x > -4 ∩ x ≤ 1.
∩ means find the members that are common between two sets.
This means that we need to find the set of all integers that satisfy x > -4 and x ≤ 1
So, to find the low end, we find the lowest integer that satisfies x > -4, which is -3.
Now, to find the high end, we find highest integer that satisfies x ≤ 1, which is 1.
So x = {-3, -2, -1, 0, 1}

Answer:
10/9
Step-by-step explanation:
average rate of change in 0≤x≤9
=(3-(-7))/(9-0)=10/9
Answer:
The solution is 10/9
Step-by-step explanation:
Step 1: identify the right approach:
Given a function g(x) over a period of time, to find the average rate of change of g(x) over this period of time, we divide the change in g(x) by the change in x.
Step 2: Perform the calculation:
As shown in picture,
x = 0 => g(x) = -7
x = 9 => g(x) = 3
=> The change of x over interval [0, 9] is:
x_change = 9 - 0 = 9
=> The change of g(x) over interval [0, 9] is:
g(x)_change = 3 - (-7) = 10
=> The average rate (r) of change of g(x) over interval [0, 9] is:
r = g(x)_change/x_change = 10/9
Hop this helps!

An object launched vertically from a point that is 37.5 feet above ground level with an initial velocity of 48.6 feet per second can be represented by the equation h=−16t^2+48.6t+37.5, where h is the height of the object and t is the time after the object is launched. How long does it take the object to hit the ground?
Answers
Answer: 3.675 seconds
Step-by-step explanation:
Hi, when the object hits the ground, h=0:
h=−16t^2+48.6t+37.5
0=−16t^2+48.6t+37.5
We have to apply the quadratic formula:
For: ax2+ bx + c
x =[ -b ± √b²-4ac] /2a
Replacing with the values given:
a=-16 ; b=48.6; c=37.5
x =[ -(48.6) ± √(-48.6)²-4(-16)37.5] /2(-16)
x = [ -48.6 ± √ 4,761.96] /-32
x = [ -48.6 ± 69] /-32
Positive:
x = [ -48.6 + 69] /-32 = -0.6375
Negative:
x = [ -48.6 - 69] /-32 = 3.675 seconds (seconds can't be negative)

Triangle ABC was translated according to the rule T4.5, –6.2(x, y) to form A’B’C’ as shown. What are the coordinates of point C of the pre-image
Answers
Answer:
(-5.5, 3.2)
Step-by-step explanation:
According to the question, the data provided in the question is as follows
(x,y) = (x + 4.5 , y -6.2)
Now
(x + 4.5 , y -6.2) = (-1,-3)
Therefore
x + 4.5 = -1
So, the x equals to
= -1 - 4.5
= -5.5
Now
y - 6.2 = -3
So, the y is
= - 3 + 6.2
= 3.2
hence, the coordinates of point C of x and y is (-5.5, 3.2)
Therefore the third option is correct

Kimmy walks to school each day. She uses a map that is drawn on a standard (x,y) coordinate plane to see how far she walks. On the map, one coordinate unit represents 100 feet. Her house is located at (8, 4) and the school entrance is located at (-4, -2). Each day, she walks directly from her house to the school entrance. To the nearest foot, what is the distance Kimmy walks to school each day?
Answers
Answer:
1342 feet
Step-by-step explanation:
Kimmy's house is located at (8, 4)
The school entrance is located at (-4, -2).
To find the distance Kimmy walks to school every day, we use the Distance formula:
[tex]\text{Distance =}\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Where [tex](x_1,y_1)=(8, 4),$ and (x_2,y_2)=(-4, -2).[/tex]
[tex]\text{Distance=}\sqrt{(-4-8)^2+(-2-4)^2}\\=\sqrt{(-12)^2+(-6)^2}\\=\sqrt{144+36}\\=\sqrt{180} \\=13.42$ Units\\Since 1 coordinate unit represents 100 feet.\\\\Distance walked by Kimmy to school every day\\=13.42*100 feet\\=1342 feet (to the nearest foot)[/tex]

The slope of AB is -2/5. Segment CD has endpoints at C(-5,3) and D(10,-3). Are AB and CD parallel, perpendicular or neither? Justify.
Answers
Answer:
Neither
Step-by-step explanation:
When I input segment CD onto a graph, I get -0.4 as the slope or 15/-6. If the lines were parallel, they would need to have the same slope which they do not have. If they were perpendicular, they would need to have different slopes so, -2/5 and 5/2 which they do not. That leaves us with the only option of neither.

Step-by-step explanation:
AB has the slope of -2/5let's see what slope the line CD has:
points are (-5, 3) and (10, -3)slope= m= (y2-y1)/(x2-x1)= (-3-3)/(10+5)= -6/15= -2/5as we see AB and CD have same slope, therefore they are parallel
which graph shows the solution to the system of linear inequalities x-4y< 4 y < x+1
Answers
Answer:
Third graph in the image attached
Step-by-step explanation:
Let's rewrite the first inequality:
x - 4y < 4
-4y < 4 - x
4y > x - 4
y > x/4 - 1
We can draw the line y = x/4 - 1, then all values above this line will be solution for this inequality (check first graph in the image attached)
Now, for the second inequality, we have:
y < x+1
We can draw the line y = x + 1, then all values below this line will be solution for this inequality (check second graph in the image attached)
Now, if we combine these solutions, we have the third graph in the image attached.
The crossing point can be found making the value of y from one line equal the value of y from the other line:
[tex]x/4 - 1 = x + 1[/tex]
[tex]x - x/4 = -2[/tex]
[tex]3x/4 = -2[/tex]
[tex]3x = -8[/tex]
[tex]x = -8/3[/tex]
[tex]y = x + 1 = -5/3[/tex]
The crossing point is (-8/3 , -5/3)

12 (9+DC) = 9*16
Divide each side by 12

9+DC = 12
Subtract 9 from each side
9+DC-9 =12-9
DC =3
Answer:
3 units
Step-by-step explanation:
We can see that triangle ADE is similar to triangle ACB.
Therefore the ratios of the lengths of their sides must be equal.
We can write AD/AC = AE/AB
we are given AD = 9, AE = 12 and AB = 12 + 4 = 16
Substituting the above values into the equation:
AD/AC = AE/AB
9 / AC = 12/16 (rearranging)
(AC)(12) = (9)(16)
AC = (9)(16)/12
AC = 12
We can also see that
DC = AC - AD
DC = 12 - 9
DC = 3 units

Answer:

Step-by-step explanation:
write it in the following manner:
-3x + 7 - 5x = 15
-8x + 7 = 15
-8x = 8
x = -1
Thus, the number has to be smaller than -1.
The smallest integer that makes the given inequality true is 0.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given inequality,
-3x + 7 - 5x < 15
We have to find the value of x.
(-3x - 5x) + 7 < 15
-8x < 8
Dividing whole sides by -1, the inequality sign changes.
x > -1
Smallest possible value is 0.
Hence the smallest posible value is 0.
