D. –10
Answers
Answer:
D. –10
Step-by-step explanation:
Given equation:
y = 3x – 1
what is the value of y when x equals –3?
Substitute x = -3 into the equation to find y
y = 3x – 1
= 3(-3) - 1
= -9 - 1
= -10
y = -10

Answers
Answer:
(x-7)^2 + (y+3)^2 = 49
Step-by-step explanation:
The general equation for a circle is given by
(x-h)^2 + (y-k)^2 = r^2
where ( h,k) is the center and r is the radius
(x-7)^2 + (y- -3)^2 = 7^2
(x-7)^2 + (y+3)^2 = 7^2
(x-7)^2 + (y+3)^2 = 49
Answer;
(x-7)^2 + (y+3)^2 = 49

There is a square field of side 45m. There is a well in this field of area of 5 sq. Metre. In the remaining part, we plant coconut trees at the rate of one plant per sq.Metre . How many trees can be planted in the field? If the cost of planting one tree is Rs. 75. What is the total cost of planting the trees?
Answers
Answer:
Numbner of plant in field = 2,020
Cost of planting trees = R.s 151,500
Step-by-step explanation:
GIven:
Side of square field = 45 m
Area of well = 5 square meter
1 plant = 1 squre meter
Cost per tree = R.s 75
Find:
Numbner of plant in field
Cost of planting trees
Computtaion:
Area of planting trees = Area of filed - Area of well
Area of planting trees = [45 x 45] - 5
Area of planting trees = 2,025 - 5
Area of planting trees = 2,020 squre field
Numbner of plant in field = Area of planting trees / 1 squre meter
Numbner of plant in field = 2,020
Cost of planting trees = 75 x Numbner of plant in field
Cost of planting trees = 75 x 2,020
Cost of planting trees = R.s 151,500

Graph the equation y = x2 + 8x + 12 on the accompanying set of axes. You must
plot 5 points including the roots and the vertex. Using the graph, determine the
vertex of the parabola.
Answers
Answer:
Step-by-step explanation:
Roots: set y = x^2 + 8x + 12 = 0 and solve for x: x + 6 = 0, so x = -6 is one root. The other is x = -2. The corresponding points are (-6, 0) and (-2, 0).
y-intercept: Let x = 0. Then y = 12. The y-intercept is (0, 12).
Axis of symmetry: x = -b / (2a) => x = -8/(2*1) = -4: x = -4
Vertex y-value: evaluate y at x = - 4: (-4)^2 + 8(-4) + 12 = -4: (-4, -4)
Arbitrarily chosen x value: x = 1 => 1^2 + 8(1) + 12 = 21: (1, 21)
The five points are: (-6, 0) and (-2, 0), (0, 12), (-4, -4), (1, 21). The vertex is (-4, -4). The parabolic graph opens UP.
The vertex of the parabolic equation y = x² + 8x + 12 will be at (-4, -4).
What is the equation of the parabola?Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The equation is given below.
y = x² + 8x + 12
Conver the equation into a vertex form. Then we have
y = x² + 8x + 12
y = x² + 8x + 16 - 16 + 12
y = (x + 4)² - 4
The vertex of the parabolic equation y = x² + 8x + 12 will be at (-4, -4).
The graph is given below.

The equation represents this linear relationship for total cost is y= 5x + 15 thus option (D) is correct.
What is a linear function?A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given,
She charges a flat fee of $15 plus $5 per hour.
For x number of hours, the total cost will be as,

The function g(x) is described in the table below what is g(0)+g(4)?
Answers
Let's take a look at our table here in order to solve the problem. We need to know what g(0) and g(4) are to be able to solve.
Since we are plugging in x-values and looking for y-values, we simply need to find 0 and 4 on the left side of the table (the x side), and then find their corresponding g(x), or y, values.
g(0) = -5
g(4) = -4
Now, all that's left to do is add these two values.
-5 + -4
-9
Hope this helps!! :)
Answer:
- 9
Step-by-step explanation:
g(0) = - 5 ← value of g(x) when x = 0
g(4) = - 4 ← value of g(x) when x = 4
Then
g(0) + g(4) = - 5 + (- 4) = - 5 - 4 = - 9

P = 2 (lungime + lățime)
P = 400
Lățime = x
Lungime = 3x
Astfel, avem:
400 = 2 (3x + x)
400 = 2 (4x)
400 = 8x
Împărțiți ambele părți la 8
50 = x
Lungime = 3x
Lungime = 3 * 50
Lungime = 150 m

Given f(x) = x^2 + 2 and g(x) = 2 – x, find a simplified expression for f(2x) + g(3x).
Answers
Answer:
f(2)+g(3) = 5
Step-by-step explanation:
Given that,
f(x) = x² + 2
g(x) = 2-x
We need to find the value of f(2)+g(3).
f(2) = 2² + 2 = 6
g(3) = 2 – 3 = -1
So,
f(2)+g(3) = 6+(-1)
= 5
Hence, the value of the given expression is 5.
