Answer:
x=1
Step-by-step explanation:
f(x) is a fancy way of saying Y. So whenever you see that, you can just say its y= something.
y=-3x+4
1=-3x+4
Move the -3x to the other side where the one is. By doing this, the 3x will become positive.
3x+1=4
Now just subract one from 4
3x=3
And divide 3 from both sides.
x=1
given: -3x+20=8; prove: x=4
Answer:
4
Step-by-step explanation:
Step 1:
- 3x + 20 = 8 Equation
Step 2:
- 3x = 8 - 20 Subtract 20 on both sides
Step 3:
- 3x = - 12 Subtract
Step 4:
x = - 12 ÷ - 3 Divide
Answer:
x = 4
Hope This Helps :)
Answer:
x = 4
Step-by-step explanation:
Step 1: Write equation
-3x + 20 = 8
Step 2: Solve for x
Subtract 20 on both sides: -3x = -12Divide both sides by -3: x = 4Step 3: Check
Plug in x to verify it's a solution.
-3(4) + 20 = 8
-12 + 20 = 8
8 = 8

The value of x for the given triangle will be 111°.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
The sum of all angles inside a triangle is 180°
So,
47° + x° + 22° = 180°
x = 180° - 69° = 111°
Hence "The value of x for the given triangle will be 111°".

A)Addition
B)Subtraction
C)Multiplication
D)Division
Answer:
D
Step-by-step explanation:
Polynomials are always closed with addition, subtraction, and multiplication. Division cannot be used to close a polynomial because when you divide two polynomials, its not going to come out as polynomial. All the other operations after completed will create another polynomial.

1. Which equation shows the proportional
relationship in the table?
Time (weeks) 2 5 10
Trees Planted 130 325 650
A y = 2x
B y = 65x
C y = 130x
D y = 2x + 130
please help.
Answer:
B. [tex] y = 65x [/tex]
Step-by-step explanation:
Equation showing a proportional relationship between two quantities, is usually written as [tex] y = kx [/tex]. Where,
y = output/dependent variable
x = input/independent variable
k = constant of proportionality that exists between each pair of values given.
In this case:
y = trees planted
x = time (weeks)
To find the constant of proportionality, k, use any given pair as (x, y). Let's use (10, 650).
Substitute y = 650 and x = 10 into [tex] y = kx [/tex], and solve for the value of k.
[tex] 650 = k(10) [/tex]
Divide both sides by 10
[tex] \frac{650}{10} = k [/tex]
[tex] 65 = k [/tex]
[tex] k = 65 [/tex]
Substitute k = 65 into [tex] y = kx [/tex] to generate the equation that shows the proportional relationship in the table:
[tex] y = 65x [/tex]

**giving BRANIEST to FIRST to answer:)
Answer:
x=-7
Step-by-step explanation:
Let's solve your equation step-by-step.
−2(3x+9)=24
Step 1: Simplify both sides of the equation.
−2(3x+9)=24
(−2)(3x)+(−2)(9)=24(Distribute)
−6x+−18=24
−6x−18=24
Step 2: Add 18 to both sides.
−6x−18+18=24+18
−6x=42
Step 3: Divide both sides by -6.
−6x /−6
= 42 /−6
x=−7

do any of y’all know how to do number 7?
Answer:
f(-3) = 2
f(-1) = 2
f(8) = 1
Step-by-step explanation:
Yep! For any function f(x), you find the y value corresponding the x value. For example, in this question, it asks us to find f(-3). Therefore, you go to the line, x = -3, and see where it intersect the function (the y value). Your answer would be the y value.
The value corresponding to f(-3) seems to be 2.
The value corresponding to f(-1) seems to be -2.
The value corresponding to f(8) seems to be 1.
what is the solution to the system of equations? 3x-2y=19 y=x-7
A) (6,-1)
B) (33,26)
C) (1,-6)
D) (5,-2)
Step-by-step explanation:
3x - 2y = 19 ...1
Replace y = x-7 in ...1
3x - 2(x-7) = 19
3x - 2x + 14 = 19
x = 19 - 14
= 5
Replace x = 5 in y = x - 7
y = 5 - 7

1. given w(x)=4x
a. graph r(x)=4 x w(x). then complete the table of corresponding points on r (x).
Answer:
Step-by-step explanation:
a). When graph w(x) is transformed to r(x) = 4 × w(x), graph of w(x) is vertically stretched by a scale factor of 4.
Table for the corresponding points will be,
x w(x) r(x)
0 0 0×4 = 0
15 60 60×4 = 240
30 120 120×4 = 480
45 180 180×4 = 720
b). As discussed in part (a), graph of w(x) will be vertically stretched by a scale factor of 4 to produce the graph of r(x).
c). Since, w(x) = 4x
and r(x) = 4[w(x)]
r(x) = 4(4x) = 16x
r(x) = 16x

Mirna earned $120 baby-sitting during the spring break. She needs to save $90 for the German Club trip. She wants to spend the remainder of the money shopping. Use s for the amount of money Mirna can spend. Enter your inequality in the most simplified form.
Answer:
$30
Step-by-step explanation:
s + 90 = 120
s = 120 - 90
s = 30
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
The most simplified inequality form of the amount of money s to spend on shopping is
s ≤ 30
Where s is the amount to spend.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
