Directions Write Each Equation In Slope-Intercept Form Then Graph The Problem Is X+5y=-15
Answer:
y = -x/5 - 3
Step-by-step explanation:
Slope intercept form: y = mx + b
x + 5y = -15
5y = -15 - x
y = -15/5 -x/5
y = -x/5 - 3

Is 16+4 and 2(2w+8) equivalent?
Answer:
Below!
Step-by-step explanation:
Let us consider that 16 + 4 and 2(2w+8) are equal. Then;
⇒ 16 + 4 = 2(2w + 8)This equation can be solved in two ways. Listed below!
Method 1:
Let's simplify the left-hand-side of the equation.
⇒ 20 = 2(2w + 8)Then, divide "2" both sides of the equation to open the parentheses.
⇒ 20/2 = 2(2w + 8)/2⇒ 10 = (2w + 8)⇒ 10 = 2w + 8Subtract 8 to both sides of the equation to isolate the variable (w) and it's coefficient.
⇒ 10 - 8 = 2w⇒ 2 = 2wFinally, divide 2 to both sides of the equation to isolate the variable (w).
⇒ w = 1Therefore, 16 + 4 and 2(2w + 8) can be equal if the value of "w" is 1.
Method 2:
Let's simplify the left-hand-side of the equation.
⇒ 20 = 2(2w + 8)Then, simplify the distributive property to open the parentheses.
⇒ 20 = 2(2w + 8)⇒ 20 = 4w + 16Subtract 16 to both sides of the equation to isolate the variable and it's coefficient.
⇒ 20 - 16 = 4w + 16 - 16⇒ 4 = 4wFinally, divide 4 to both sides of the equation to isolate the variable (w).
⇒ 4/4 = 4w/4⇒ w = 1As said in method 1, 16 + 4 and 2(2w + 8) can be equal if the value of "w" is 1.

Which statement describes the solutions of this equation?
Answer:
C. The equation has two valid solutions
Step-by-step explanation:
A rational equation like this is often solved by "cross-multiplying" to eliminate the fractions. When we do that, we get ...
4(2x+10) = x(3x+1) . . . . . . . multiply both sides by (3x+1)(2x+10)
3x² -7x -40 = 0 . . . . . . . . . . rearrange to standard form
3x² -15x +8x -40 = 0 . . . . . . separate -7 into factors of 3(-40)
3x(x -5) +8(x -5) = 0 . . . . . factor pairs of terms
(3x +8)(x -5) = 0 . . . . . . . finish factoring
The zeros of these factors are not zeros of the original denominators, so neither of the solutions these give is extraneous.
3x +8 = 0 ⇒ x = -8/3
x -5 = 0 ⇒ x = 5

Two angles are supplementary to each other. If the first angle measures 58°, then
which of the following could be the measure of the second angle?
F. 122
G. 32
H. 58
J. 90
Answer:
F. 122º
Step-by-step explanation:
By definition, the sum of 2 supplementary angles is 180º
Hence 58º + x = 180º
x = 180º - 58º - 122º

3 Select the correct answer. How can you write the expression 7(b – 2) in words? A. two subtracted from the quotient of seven divided by b B. seven added to difference of b minus two C. the quotient of seven divided by b minus two D. two subtracted from seven times b E. the product of seven and the difference of b minus two
Answer:
E. the product of seven and the difference of b minus two
Step-by-step explanation:
7(b-2)
seven is being multiplied by the difference of b minus 2
So this can be written as the product of seven and the difference of b minus two.
Reasons its not the other answer choices
A. two subtracted from the quotient of seven divided by b would be (7/b) - 2
B. seven added to difference of b minus two would be 7 + (b-2)
C. the quotient of seven divided by b minus two would be 7/(b-2)
D. two subtracted from seven times b would be 7b - 2
Key Vocabulary:
Difference = Subtraction
Product = Multiplication
Quotient = Division
The product of seven and the difference of b minus 2
Calculations / Details ↓First of all the difference of 2 numbers indicates that we subtract these numbers .
For instance , here we subtract :
b - 2
so we have the difference of b minus 2
then the product means we multiply .
For instance , here we multiply 7 times the difference of b and 2 .
A number / variable before the parentheses indicates that we multiply that number times the parentheses .
So the option is E.hope helpful ~

Use the function f(x) to answer the questions.
f(x) = −16x2 + 24x + 16
Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part B: Is the vertex of the graph of f(x) going to be a maximum or a minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answer:
See Explanation
Step-by-step explanation:
A. f(x) = -16x² +24x + 16
0 = -8(2x² - 3x - 2) ⇒ -8(2x + 1)(x - 2) = 0 ⇒ x = -1/2, 2
B. f'(x) = -32x + 24 ⇒ 0 = -8(4x - 3) ⇒ x = 3/4
f''(x) = -32 ⇒ f''(3/4) = -32 ⇒ concave down ⇒ maximum
f(3/4) = -16(9/16) + 24(3/4) + 16 = -9 + 18 + 16 = 25
By the second derivative test, the point (3/4, 25) is a maximum.
C. 1. Plot the intercepts. 2. Plug in points. 3. Draw the curve.

Answer:
Option B, [tex]x =[/tex] ± [tex]9.49[/tex]
Step-by-step explanation:
Step 1: Add 90 to both sides
[tex]x^2 - 90 = 0[/tex]
[tex]x^2 - 90 + 90 = 0 + 90[/tex]
[tex]x^2 = 90[/tex]

At the end of a snow storm, Caleb saw there was a lot of snow on his front lawn. The
temperature increased and the snow began to melt at a steady rate. The depth of
snow on Caleb's lawn, in inches, can be modeled by the equation S = -2t + 18,
where t is the time, in hours, after the snow stopped falling. What is the y-intercept
of the equation and what is its interpretation in the context of the problem?
The y-intercept of the function is
The y intercept is the starting depth of the snow. In this case, it would be 18 inches (aka 1 ft + 6 inches aka 1.5 feet)
The y intercept is the starting value and it occurs when t = 0
S = -2t+18
S = -2(0)+18
S = 0+18
S = 18
At time t = 0, the depth of the snow is S = 18 inches. As t increases, the value of S will decrease.

Jack has a mask collection of 500 masks. He keeps 235 of the masks on his wall. What percentage of Jack's mask collection does he keep on his wall?
Answer:
47%
Step-by-step explanation:
First we need to find the ratio of masks on Jack's wall to the total number of masks, which is 235/500. Now we need to make the denominator 100 in order to find the percentage by dividing the numerator and denominator by 5 to get 47/100. Therefore the percentage of Jack's mask collection that is on his wall is 47%.
