PLease answer for 10 points
Answer:
C
Step-by-step explanation:
Use the table to write a linear function that relates y to x .
Answer:
y = -3x + 2
Step-by-step explanation:
The linear equation is in the form
y = mx + b
where m is the slope and b is the y-intercept
the slope can be calculated using two points
Let us have; (-2,8) and (0,2)
The equation of the slope is ;
m = (y2-y1)/(x2-x1) = (2-8)/(0+2) = -6/2 = -3
So for the y-intercept, we select any of the points to substitute
Let us have (0,2)
Substitute this into;
y = -3x + b
2 = -3(0) + b
b = 2
So the equation is;
y = -3x + 2
2. Sara's apple pie recipe calls for 7 apples. She bought 20 apples when she went to the store. What percent of the apples will she use for the pie?
Solve for w:
10
4
W +6
16
Answer:
Step-by-step explanation:
The chords, when cut anywhere along their length so that there is one intersection point, will produce the following relationship for this question.
(w + 6)*4 = 16*10 Remove the brackets
4*w + 24 = 160 Subtract 24 from both sides
4w = 160 - 24 Combine the right
4w = 136 Divide by 4
w = 136/4
w = 34

Answer:
x > -[tex]\frac{12}{5}[/tex] or x > -2.4
Step-by-step explanation:
-9x > 9 + 3(-[tex]\frac{1}{3}[/tex]x + 1) - 3x
-9x > 9 -x + 3 - 3x
-9x > 12 - 4x
-5x > 12
x > -[tex]\frac{12}{5}[/tex] or x > -2.4
In the diagram mz3= x+ 30 and mz4 =2x-80. What is the measure of angle 3?
Given:
Consider the below figure attached with this question.
[tex]m\angle 3=(x+30)^\circ[/tex] and [tex]m\angle 4=(2x-80)^\circ[/tex].
To find:
The measure of angle 3.
Solution:
From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.
We know that, vertically opposite angles are always equal. So,
[tex]m\angle 3=m\angle 4[/tex]
[tex](x+30)^\circ=(2x-80)^\circ[/tex]
[tex]x+30=2x-80[/tex]
[tex]x-2x=-30-80[/tex]
[tex]-x=-110[/tex]
[tex]x=110[/tex]
Now,
[tex]m\angle 3=(110+30)^\circ[/tex]
[tex]m\angle 3=140^\circ[/tex]
Therefore, the measure of angle 3 is 140 degrees.
The area of a square is represented by the expression 16x4y8. Which expression could represent the length of one side of the square?
Answer:
4 sq 8
Step-by-step explanation:
The expression that could represent the length of one side of the square is; [tex]4x^2y^4[/tex].
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol it can also be used to indicate the logical syntax's order of operations and other features.
Given that;
The area of the square A = [tex]16x^4y^8[/tex]
Consider that a is the side length of the square
The area of the square is given by;
[tex]\Rightarrow A=(\text{side length})^2[/tex]
So, we can write the expression as;
[tex]\Rightarrow a^2=16x^4y^8\\\\\Rightarrow a=4x^2y^4[/tex]
Hence, the length of each side is 4x^2y^4

the equation is 7x-3/9 > 8-2x
Answer:
Option C
Step-by-step explanation:
[tex]\frac{7x-3}{9} \geq 8-2x\\\\7x-3\geq 9(8-2x)\\\\7x-3\geq 72-18x\\\\7x+18x\geq 72+3\\\\25x\geq 75\\\\x\geq 3[/tex]
Option A and Option C are almost same but if we look close Option A has an open circle dot on x = 3 where as Option C has a closed circle which means that small circle at x = 3 is colored that represents [tex]x\geq 3[/tex]

(4,0)
Oy-x-1
Oy-1
45
o,-1)
Answer:
the third option is the answer, y= 1/4x-1
Step-by-step explanation:
graph line in standard form:
[tex]y = mx + c[/tex]
where m = slope and c = y-intercept
1) find the slope
slope formula:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
use the two coordinates given in the graph
i/ (0,-1)
x1 = 0
y1 = -1
ii/ (4,0)
x2 = 4
y2 = 0
substitute the values into the formula
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] \frac{0 - ( - 1)}{4 - 0} [/tex]
[tex] \frac{1}{4} [/tex]
thus, m = 1/4
2) find the y-intercept
* y-intercept is the value of y that cuts through the y-axis
based on the graph, the y-intercept is -1
thus, c = -1
3) substitute the value of m and c into the standard form formula
[tex]y = mx + c[/tex]
[tex]y = \frac{1}{4} x - 1[/tex]
