Solve the inequality and graph the solution.
4x - 5 ≥ 7
Answer:
x=3
Step-by-step explanation:
it would go over the point 3,7 on the graph with a positive slope
The given inequality is solved to obtain as x ≥ 3.
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The given inequality can be solved as follows,
4x - 5 ≥ 7
Subtract 7 from both sides to obtain,
4x - 5 - 7 ≥ 0
=> 4x - 12 ≥ 0
=> 4x ≥ 12
=> x ≥ 3
The graph for the given inequality is shown as below,
Hence, the solution for the given inequality is x ≥ 3.

Answer:
416Step-by-step explanation:
For this to have infinitely many solutions, the left side and right side must simplify to the same expression. The left side is already simplified, so we need to find the right numbers for the right side.
Coefficient of x:
7x = __x + 3x
4x = __x . . . . . . subtract 3x; next divide by x
4 = __ . . . . . the required x-coefficient is 4
Constant term:
-8 = 8 -__
-16 = -__ . . . . . subtract 8
16 = __ . . . . . . multiply by -1
__
The numbers that go in the boxes are 4 and 16.
A ladder is 12 metres long . It leans against a wall with one end on the ground 7 metres from the wall. The other end just reaches a windowsill. Calculate the height of the windowsill above the ground.
i need an explanation please...
Answer:
window sill height =9.75 meters
Step-by-step explanation:

height^2=144-49=95
height=9.75
WILL GIVE BRAINLIEST Which of the following describes the quotient of 3 and -30?
A.
The quotient is an irrational number.
B.
The quotient is a rational number.
C.
The quotient is undefined.
D.
The quotient is an integer
Answer:
if i am correct the answer is A
Step-by-step explanation:
The quotient of 3 and -30 is a rational number. The correct answer would be an option (B).
What is the Quotient?A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient. The dividend contains the divisor a specific number of times.
The quotient of 3 and -30 is:
3 ÷ (-30) = -0.1
Therefore, the quotient is a rational number. Option B is correct.
A rational number is a number that can be expressed as a ratio of two integers, where the denominator is not zero. In this case, -0.1 can be expressed as the ratio of the integer -1 and the integer 10, where the denominator 10 is not zero.
Note that the quotient is negative because we are dividing a positive number (3) by a negative number (-30).

please help I attached a picture
Answer:
option (3)
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = x² - 12x + 7
Using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 12x
f(x) = x² + 2(- 6)x + 36 - 36 + 7
= (x - 6)² - 29
with vertex (h, k ) = (6, - 29 )

Find the value of y.
Answer:
y = 95° (being corresponding angle)
it is very easy.
you can also do
Answer:
The value of y is 110 degrees
Step-by-step explanation:
-we know that the Angle sum property of a quadrilateral is 360 degrees.
- so we can find the 4th angle
- and find y through the linear pair method.
The fourth angle=70 degrees
And y=180-70=110(Linear pair)

Hi! So what you will need to know is pythagorean theorm.
What the theorm basically says is a^2 + b^2 = c^2.
-- The (a,b,c) are referring to the sides of the triangles (3 letters for 3 sides).
Take note that "c" is always the side opposite of the right angle.
The other known side could be "a" or "b"
Taking a look at problem 9, identify the "c" value. The "c" value would be 35.
Then indentify the value of "b" or "a". "a" would = 20.
Plug it into the equation:
20^2 + b^2 = 35^2
400 + b^2 = 1225
solve for b.
1. subtract 400 from both sides.
b^2 = 825
b = [tex]\sqrt{825}[/tex]
you could solve for the square root but it would give a decimal numbers but I'm not sure what the teacher is looking for.
If you get the answer just give me the full answer please. No matter the length.
Answer:
CD = 4
Step-by-step explanation:
I believe you know the geometric mean for altitudes?
CD = √AD * DB = √8 * 2 = √16 = 4
If you are not aware of this theorem, then use the similarity of triangles.
ADC ~ CDB
AD/DC = CD/DB (cross-multiply)
CD^2 = AD*DB,
CD = √AD * DB = √8 * 2 = √16 = 4

Round 72.178 to the nearest hundredth.
Answer:
72.18
Step-by-step explanation:
The hundreth place is the second to the right of the decimal. So the number in the hundreths place is 72.178. When rounding, you look at the number behind the number you are rounding to. In this case, you want to look at the 8. If the number is 5 or above, you round up. 8 is above 5 so you round the 7 to an 8.
Answer: 72.18
Step-by-step explanation:

enough drinks for 28 people, how many cups of orange juice will she
need? *
Answer:
11 1 /2 ( 11 and a half)
Step-by-step explanation:
If you noticed 7 and 2 are five numbers away.
To solve this I just added one to both of them until the sum was equal to 28.
If I had added one to 16 and 11, it would have given me 29, so I added a half.
That gave me 28.
Tyrone went to a basketball game and bought a jersey that was on sale at a 30% discount. He also bought a hat that cost $37.89. Tyrone spent a total of $83.39. Write an equation to find the original cost of the jersey
Answer:
Jersey cost (without discount)= $65
Step-by-step explanation:
First, we need to determine how much he spent on the jersey:
Jersey cost (with discount)= 83.39 - 37.89
Jersey cost (with discount)= $45.5
Now, the original cost of the jersey:
Jersey cost (without discount)= discount cost / (1 - discount)
Jersey cost (without discount)= 45.5 / 0.7
Jersey cost (without discount)= $65

Alright all we need to know is to understand our brackets
So 3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}
3+20-5-9+4-3(1-5)
Step 2
3+20-5-9+4-3(1-5) Simplify
18-9+4-3(1-5)
Step 3
18-9+4-3(1-5)
13-3(1-5)
13-(-12) Here is the tricky part (We aren't going to subtract because the brackets multiply the equations
So,
13+12=25
