Answer:
-5
Step-by-step explanation:
Remember the slope intercept form:
y = mx + b
m = Slope value
b = y-intercept
So in this case,
y = (-5)x + b
m = -5
b = 1
Thus the answer is -5

A 12-ounce cup of coffee costs $2.88. If the unit price remains the
same, how much would 3 quarts of coffee cost?
The points (1,6) and (3, 10) fall on a particular line. What is its equation in slope-intercept form?
Answer:
y=2x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(10-6)/(3-1)
m=4/2
m=2
y-y1=m(x-x1)
y-6=2(x-1)
y=2x-2+6
y=2x+4
The number 70 is decreased to 41. What is the percentage by which the number was decreased, to the nearest tenth of a percent?
Answer:
Decreased percent = 41.4 % (Approx.)
Step-by-step explanation:
Given:
Old number = 70
New number = 41
Find:
Decreased percent
Computation:
Decreased number = 70 - 41
Decreased number = 29
Decreased percent = [29 / 70]100
Decreased percent = 41.42%
Decreased percent = 41.4 % (Approx.)

Use the function f(x) to answer the questions:
f(x) = 4x2 − 7x − 15
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:
Part A & B
Step-by-step explanatPart A:
f(x) = 4x ^ 2 - 7x - 15
0 = 4x ^ 2 - 7x - 15
a = 4, b = -7, c = -15
a x c = -60
-12 x 5 = -60
-12 + 5 = -7
(4x + 5)(4x - 12)
4x ^ 2 - 12x I + 5x - 15
4x(x - 3) + 5(x - 3)
(x - 3)(4x + 5)
x = 3 x = -1.25 or -5/4
Part B:
Minimum point
(x1 + x2)/2
(3 -1.25)/2 = 0.875
f(x) = 4x ^ 2 - 7x - 15
f(0.875) = 4(0.875) ^ 2 - 7(0.875) - 15
f(0.875) = 3.06 - 6.125 - 15
f(0.875) = -18.065ion:

A. (3,-5)
B. (-5,3)
C. (3,5)
D. (-5, -3)
Your answer is A!
Step-by-step explanation:
Your answer is A!
The coordinate point from the given graph is (3, -5). Therefore, option A is the correct answer.
What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
From the given coordinate plane, the coordinate point lies in fourth quadrant.
Where, x-coordinate is positive and y-coordinate is is negative.
The coordinate point correspond to x-axis is 3 and coordinate point correspond to y-axis is 5.
So, the coordinate point is (3, -5)
Therefore, option A is the correct answer.

A right angled triangular prism has length 3m, breadth 2m and height 2.5m. If the mass of the prism is 3.4kg, find its density
Answer:
The density of the prism is 0.453 kilograms per cubic meter.
Step-by-step explanation:
Let suppose that mass in the prism is uniformly distributed. Then, the definition of density ([tex]\rho[/tex]), in kilograms per cubic meter, is defined by the equation below:
[tex]\rho = \frac{m}{V}[/tex] (1)
Where:
[tex]m[/tex] - Mass, in kilograms.
[tex]V[/tex] - Volume of the right angle triangle prism, in cubic meters.
Besides, the volume of the right angle triangle prism is:
[tex]V = \frac{1}{2}\cdot b\cdot h\cdot l[/tex] (2)
Where:
[tex]b[/tex] - Breadth of the base, in meters.
[tex]h[/tex] - Height of the base, in meters.
[tex]l[/tex] - Length of the base, in meters.
If we know that [tex]b = 2\,m[/tex], [tex]h = 2.5\,m[/tex], [tex]l = 3\,m[/tex] and [tex]m = 3.4\,kg[/tex], then the density of the prism is:
[tex]V = 7.5\,m^{3}[/tex]
[tex]\rho = 0.453\,\frac{kg}{m^{3}}[/tex]
The density of the prism is 0.453 kilograms per cubic meter.

8x2 – 4x = 363
Answer:
- x = 81 and 3/4
Step-by-step explanation:
8 × 2 – 4x = 363
16 - 4x = 363
Subtract 16 from each side:
16 - 16 - 4x = 363 - 16
- 4x = 327
Divide each side by 4:
- 4x ÷ 4 = 327 ÷ 4
- x = 81 and 3/4
Paulo has 110 of a dollar in his pocket. How many dollars does he have?
I just need help on these two questions
Answer:
Q1) y= 2
Q2) y= 4
Step-by-step explanation:
Q1) If you sub in x as -1, 2 to the power of -1 is 0.5. You always solve the power first, not the multiplication. So then you do 0.5 times 4 and you get 2.
Q2) If you sub in x as 0, anything to the power of 0 becomes 1. 2 to the power of 0 is 1. Then you do the multiplication, 4 times 1 = 4
