Step 1: Define inequality
5x - 7 > 4x + 8
Step 2: Solve for x
Subtract 4x on both sides: x - 7 > 8Add 7 on both sides: x > 15Here we see that any value x that is greater than 15 would work as a solution to this inequality.

*elimination
*substitution
Answer:
substitution
Step-by-step explanation:
I would choose substitution because the first equation can easily be set in terms of y, then substituted into the second equation, while to eliminate you would have to multiply on of the equations by a number and make it negative in order to eliminate.

What is the range of the quadratic function graphed below?
Answer:
x
Step-by-step explanation:
he domain of a quadratic function in standard form is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.
Answer:
The range is y [tex]\geq 1[/tex].
Step-by-step explanation:
The graph is shifted up 1 unit, so the range will be everything positive after 1. Anything below 1 would not be in the range.

General Formulas and Concepts:
Order of Operations: BPEMDAS
Properties
Subtraction Property of EqualityStep-by-step explanation:
Step 1: Define equation
m + 6 = -4
Step 2: Solve for m
Subtract 6 on both sides: m = -10Step 3: Check
Plug in m to verify it's a solution.
Substitute: -10 + 6 = -4Add: -4 = -4The zeros of a quadratic function are 1 and 7. To which factored quadratic expression is this function related?
The factored quadratic expression is this function related is to be considered as the (x - 1) and (x-7).
Calculation of the factored quadratic expression:Since The zeros of a quadratic function are 1 and 7.
So,
if we do
(x - 1) = 0
x = 1
And,
(x- 7) = 0
x = 7
Based on this, we can say that The factored quadratic expression is this function related is to be considered as the (x - 1) and (x-7).

In Triangle ABC, ∠A + ∠B = 65° and ∠B + ∠C = 140°.Find the value of ∠B and ∠C.
Can anybody pls give the answer fast...
A + B = 65...Equation 1
B + C = 140...Equation 2
Solve Equation B for C.
C = 140 - B
The sum of the angles in a triangle is 180 degrees.
We know that A + B = 65.
65 + C = 180
We know that C = 140 - B.
65 + 140 - B = 180
205 - B = 180
-B = 180 - 205
-B = -25
B = -25/-1
B = 25
Plug B = 25 into B + C = 140 to find angle C.
25 + C = 140
C = 140 - 25
C = 115
Angle B = 25°.
Angle C = 115°.

Can someone Help me plz ASAP
Answer:
Please check the explanation.
Step-by-step explanation:
Given the angles of the trapezoid
x°x°1/2x°1/2x°As the sum of angle measure = 360°
i.e.
[tex]x+x+\frac{1}{2}x+\frac{1}{2}x=360[/tex]
[tex]x+x+2\cdot \frac{1}{2}x=360[/tex]
[tex]2x+2\cdot \frac{1}{2}x=360[/tex]
[tex]2x+x=360[/tex]
[tex]3x=360[/tex]
[tex]\frac{3x}{3}=\frac{360}{3}[/tex]
[tex]x=120[/tex]
The value of x = 120°
Hence, the angle measure will be:
x°=120x°=1201/2x°=1/2(120)=601/2x°=1/2(120)=60Therefore, listing the angle measure in order from least to greatest
60°, 60 , 120 , 120°

Aneil wants to plant tomato plants and lettuce plants in a 60-square-foot garden. The tomato plants take up 2 square feet, and the lettuce plants take up 3 square feet. The equation 2x + 3y = 60 describes the number of tomato plants, x, and lettuce plants, y, that Aneil can plant in the garden. Graph this function and find the intercepts. What does each intercept represent?
Step-by-step explanation:
The more regular way of presenting such a graph is y = -2/3 x + 20
(Put the x on the right and made sure that the y has a coefficient of 1.)
Coefficient means the number in front of the letter (in this case).
x intercept = 30
(30,0)
y intercept = 20
(0,20)
The intercepts mean
The y intercept means the whole garden contains nothing but lettuce. (20)
The x intercept means the whole garden contains nothing but tomatoes.(30)

∠TUS+12x+81=180
∠TUS=99-12x
∠TUS+∠TUV=180
99-12x+24x+9=180
108+12x=180
12x=72

There you go. Try and use these solutions to solve others for yourself. You got it.
Answer:
x = 6°∠TSU = 72°Step-by-step explanation:
Angle TUV is exterior angle to triangle TUS. Exterior angle measure is equal to sum of non-adjacent interior angles:
∠TUV = ∠STU + ∠TSU24x + 9 = 81 + 12xSolving for x
24x - 12x = 81 - 912x = 72x = 72/12x = 6°Finding angle measure of ∠TSU

A group of students is arranging squares into layers to create a project. The first layer has 4 squares. The second layer has 8 squares. Which formula represents an arithmetic explicit formula to determine the number of squares in each layer?
f(1) = 4; f(n) = 4 ⋅ d(n − 1), n > 0
f(1) = 4; f(n) = 4 ⋅ d(n + 1), n > 0
f(1) = 4; f(n) = 4 + d(n + 1), n > 0
f(1) = 4; f(n) = 4 + d(n − 1), n > 0
Answer:
f(1) = 4; f(n) = 4 + d(n - 1), n > 0.
Step-by-step explanation:
This arithmetic sequence has a common difference of d with first term = 4.
f(1) = 4; f(n) = 4 + d(n - 1), n > 0.

Follow these steps to construct a triangle to represent the given information:
Draw a ray in the direction S 20° E from point P. Create a circle with radius 43.5. (Note that you'll be scaling down all the distances in miles by a factor of 10: 435 ÷ 10 = 43.5.) Label the point where the circle intersects the ray as C (Cali).
Draw a ray in the direction S 81° E from P. Mark an arbitrary point on this ray, and label it S.
Create a line through point S that is parallel to the north-south line through P.
Using the line passing through point S, draw a ray that is S 53° W.
Move point S along line PS until the ray S 53° W from S passes through point C. This position of S locates San Cristobal.
