To find:
The solution for the given compound inequality
Solution:
We have, compound inequality [tex]2x-3 < 7[/tex] and [tex]5-x \leq 8[/tex].
For [tex]2x-3 < 7[/tex],
Add 3 on both sides.
[tex]2x < 7+3[/tex]
[tex]2x < 10[/tex]
Divide 2 on both sides.
[tex]x< 5[/tex] ...(i)
For [tex]5-x \leq 8[/tex],
Subtract 5 from both sides.
[tex]-x \leq 8-5[/tex]
[tex]-x \leq 3[/tex]
Divide both sides by -1. So, the sign of inequality is changed.
[tex]x \geq -3[/tex] ...(ii)
Using (i) and (ii), we get the solution of given compound inequality as
[tex]x \geq -3[/tex] and [tex]x< 5[/tex]
Therefore, the correct option is D.

Answer:
f(2) = -5
Step-by-step explanation:
For this problem, we are evaluating the graph of f(x), meaning at the value of x, we want the y-value.
Note, when x = 2 on the graph, the only y coordinate available is y = -5.
Hence, when we evaluate f(x) for x = 2, we get y = -5. f(2) = -5.

Anybody wanna help?ASAP?
Answer:
x=113º
Step-by-step explanation:
67 + x is a linear pair
they would be supplementary if they were next to each other
the 67º represents the acute angle directly next to xº
so
x+67= 180º
subtract 67º from both sides
180-67=113
x=113º
Lines x and y are parallel. Write an equation that represents the relationship between b and e. Explain how you know this equation is always true. Your explanation should use AT LEAST TWO of the following terms: vertical angles, corresponding angles, congruent, supplementary.
please help
Answer:
m∠b + m∠e = 180°
Step-by-step explanation:
Lines x and y are the parallel lines and a transversal line is intersecting these lines.
∠b ≅ ∠h [Vertical angles]
∠h ≅ ∠f [Corresponding angles]
Therefore, ∠b ≅ ∠f [Congruent angles]
m∠f + m∠e = 180° [Supplementary angles]
m∠b + m∠e = 180° [Since, ∠b ≅ ∠f]
Therefore, equation representing the relation between ∠b and ∠e is,
m∠b + m∠e = 180°
The required equation that represents the relationship between b and e is m<b + m<e = 180
From the given diagram, we can see that the line x and y are cut by a transversal. This shows that the following statements are true;
m<b and m<g are supplementary i.e m<b + m<g = 180
Also m<b and m<f are equal (alternate interior angle)
m<b = m<d (vertically opposite angle)
Also, since m<d and m<e are supplementary angles (angle on a straight line), then m<b and m<e are also supplementary
Hence the required equation that represents the relationship between b and e is m<b + m<e = 180

Answer:
The number of smothered steak dinners that can be made is 9,800

Find three consecutive EVEN integers such that the sum of the smallest number and twice the middle number is 20 more than the largest number.
Answer:
10, 12 and 14Step-by-step explanation:
x - an integer
2x - an even integer (the first and the smaller of the three)
Consecutive integers increase always by 2
2x+2 - next even integer consecutive to 2x (the middle one)
2x+2+2=2x+4 - the last consecutive even integer (the largest)
2•(2x+2) - twice the middle number
2x+2•(2x+2) - the sum of the smallest number and twice the middle one
2x+4+20 - 20 more than the largest number
2x+2•(2x+2) = 2x+4+20
2x + 4x + 4 = 2x + 24
-2x -2x
4x + 4 = 24
÷2 ÷2
2x + 2 = 12 ← the middle number
-2 -2
2x = 10 ← the smallest number
2x+4 = 10 + 4 = 14
Check: 10+2•12=34; 14+20=34

The point-slope form of the equation of the line that passes through (-9, -2) and (1, 3) is y – 3 = {(x - 1). What is the
slope-intercept form of the equation for this line?
Oy=1x+2
Oy={x-4
O y = x + 3/2
Oy=2x-
2.
Option A is the correct answer, y = x + 2
y - 3 = x-1
If you bring the 3 to the R.H.S, it becomes y = x + 2
If you substitute the values,
3 = 1 + 2
3 = 3
Thus, e equation is correct
The slope-intercept form of the equation for this line is y = 1/2 x + 5/2
First, we need to get the slope of the equation passing through the coordinate (-9, -2) and (1, 3)
m = 3+2/1+9
m = 5/10
m = 1/2
The equation in point slope form is given as y - 3 = 1/2(x - 1)
2(y - 3) = x - 1
Write in slope intercept form
2(y - 3) = x - 1
2y - 6 = x - 1
2y = x + 5
y = 1/2 x + 5/2
Hence the slope-intercept form of the equation for this line is y = 1/2 x + 5/2

Let's see what to do buddy...
_________________________________
Step (1)
We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :
[tex](n - 2) \times 180[/tex]
Our figure has 5 sides ;
So , sume the interior angles of it equals :
[tex](5 - 2) \times 180 = 3 \times 180 = 540 \\ [/tex]
_________________________________
Step (2)
First look at the photo which I post.
According it we have :
[tex](180 - x) + 120 + 85 + (2x - 10) + 90 = 540 \\ [/tex]
[tex]2x - x + 475 - 10 = 540[/tex]
[tex]x + 465 = 540[/tex]
Subtract the sides of the equation minus 465 :
[tex]x = 540 - 465[/tex]
[tex]x = 75[/tex]
