Answer:
Horizontal line which goes through the y -axis at the coordinate ( 0, C/A ).
Step-by-step explanation:
Since A is not 0 then C can not be 0 This is a logical deduction from the given formula Ay = C
The equation of any line is y = ax + b, where a is the incline and b is the intercept between the line and the y- axis.
Ay = C
Divide left and right of the = sign by A and you get:
y = C/A
This is the formula for a horizontal line which goes through the y -axis at the coordinate ( 0, C/A ).
Because it is a horizontal line it has an incline of 0.
So a = 0
y = ax + b
a = 0 and b = C/A
y = 0*x + C/A
y = 0 + C/A
y = C/A

Help someone please !!!!!!!!!!!!!!!!!!!!!!! The temperature one winter morning is -12 degrees fahrenheit,by noon,the temperatures rises by 5 degrees,and by 4p.m,the temperatures is 0 degrees. By how many degrees does the temperatures rise between noon and 4p.m., in degrees fahrenheit??
Answer:
The temperature rises 7 degrees between noon and 4pm.
Step-by-step explanation:
First, you add 5 to the -12. This gets you to the answer of 7. Then, since the temp. rises to 0 degrees by 4, you know that the difference between noon and 4 pm is 7 degrees.
Does the point (2, 0) satisfy the equation y = x?
Answer:
no
Step-by-step explanation:
y = x
Substitute the point into the equation
0=2
This is not true so the point is not a solution
Hey there! I'm happy to help!
The point (2,0) does not satisfy the equation y=x. That means that x and y have to be equal. 2 and 0 are not equal. A point like (4,4) would satisfy that.

Which parallelogram has an area of 60 square units?
Answer:
The answer is B
Step-by-step explanation:
Multiply base•height
Finding the area of each parallelogram, applying the formula, it is found that the parallelogram D has an area of 60 square units.
---------------------------
Similarly to a rectangle, the area of a parallelogram is given by height multiplied by base, that is:
[tex]A = hb[/tex]
---------------------------
In item A, the height is of 15 units and the base is of 10 units, thus, the area, in square units, is of [tex]15 \times 10 = 150[/tex].In item B, the height is of 6 units and the base is of 10.2 units, thus, the area, in square units, is of [tex]6 \times 10.2 = 61.2[/tex].In item C, the height is of 15 units and the base is of 15 units, thus, the area, in square units, is of [tex]15 \times 15 = 225[/tex].In item D, the height is of 10 units and the base is of 6 units, thus, the area, in square units, is of [tex]10 \times 6 = 60[/tex], which means that this is the correct option.A similar problem is given at https://brainly.com/question/14099239

The perimeter of a rectangular tabletop is 384 cm. It's width is 3/5 of its length. Find the dimensions of the tabletop
Answer:
Length: 120cm, Width: 72cm
Step-by-step explanation:
Let x = length
Let 3x/5 = width
2x+2(3x/5)=384
2x+(6x/5)=384
16x/5=384
16x=1920
x=120cm
Substitute 120 for x in width
360/5 = width
width = 72cm

A student is given a quadratic equation in vertex form. He determines the vertex and axis of symmetry, and then sketches the parabola so that it is symmetrical about the axis of symmetry. Is this sufficient? Explain.
Answer:
The information with which the parabola is constructed is insufficient
Step-by-step explanation:
The vertex form of a quadratic equation is given as follows;
f(x) = a(x - h)² + k
The steps to draw the graph of a quadratic function given in vertex form, we are required to do the following;
1) Definition of the variables, (a, h and k) of the quadratic equation (given in vertex form)
The vertex of the quadratic equation in vertex form is (h, k)
2) Given that the vertex point is given, the vertex point is then plotted on the graph
3) Draw the parabola axis of symmetry that passes through the vertex point
4) Determine the direction to which the parabola opens from the sign of the variable a as follows;
i) When a is positive, the parabola opens upwards
ii) When a is negative, the parabola opens downwards
5) Determine if the parabola has x-intercepts and plot them
A parabola has x intercepts when;
i) The parabola opens downwards, that is, the variable, a, is negative and also the vertex (h, k) is above the x-axis or k is positive
ii) The parabola opens upwards, that is, the variable, a, is positive and also the vertex (h, k) is below the x-axis or k is negative
6) Determine y-intercepts and plot them as follows;
At the y-intercept, x = 0, therefore;
f(x) = a(x - h)² + k
f(0) = a(0 - h)² + k = a·h² + k
6) If any additional points are required, they should plotted and then the graph of the function is then drawn making sure to be symmetrical about the vertex and to pass through all the plotted points.
Point F is the midpoint of segment DE. DF = 2x+6 and DE = 2x+36. Find DE.
Answer: It already tells you what DE= 60
Step-by-step explanation:
Since F is the midpoint of DE that means DF=FE
So create equation [tex]2x+6+2x+6=4x+12[/tex]
When DF and FE is added your answer should equal DE
So you write the equation [tex]4x+12=2x+36[/tex] to find x and once x is found substitute your answer for x
[tex]4x+12(-12)=2x+36(-12)[/tex] subtract 12 on both sides 36-12= 24
[tex]4x=2x+24[/tex] subtract 2x on both sides 4x-2x=2x
[tex]2x=24[/tex] divide 2 into both sides 24/2=12 x=12
[tex]4(12)+12=2(12)+36[/tex]
4x12=48+12=60 2x12=24+36=60
When p2 – 4p is subtracted from p2 + p – 6, the result is . To get p – 9, subtract from this result.
Answer:

How do I determine the 50th term for the sequence
-5, -1, 3, 7, 11
solve the system
4x + 2y = 10
x = y + 13
Answer:
[tex]x = 6[/tex]
[tex]y = -7[/tex]
Step-by-step explanation:
We have the system of equations:
[tex]4x+2y=10\\x=y+13[/tex]
Let's solve by substituting. We know that [tex]x=y+13[/tex], so we can substitute [tex]y+13[/tex] in as [tex]x[/tex] in the equation [tex]4x+2y=10[/tex].
[tex]4(y+13) + 2y = 10[/tex]
Simplify this down so that we have [tex]y[/tex] on one side of the equation:
[tex]4y + 52 + 2y = 10\\\\6y + 52 = 10\\\\6y = -42\\\\y = -7[/tex]
Now that we know the value of [tex]y[/tex], we can substitute it in to the equation [tex]x = y+13[/tex] to find [tex]x[/tex].
[tex]x = -7+13\\\\x = 6[/tex]
Hope this helped!
Answer: (6,-7)
Step-by-step explanation:
4x +2y = 10
x = y + 13 Substitute the value of x into the first equation to solve for y.
4(y + 13) +2y = 10 apply the distributive property on the left side
4y + 52 + 2y = 10 Combine like terms on the left side
6y + 52 = 10 Subtract 52 from both sides
-52 -52
6y = -42
y= -7
The value of y so input it into one of the equations to solve for x
4x + 2(-7) = 10
4x - 14 = 10
+14 +14
4x = 24
x= 6

What are the vertex and x-intercepts of the graph of the function given below?
y = x2 - 2x-35
A. Vertex: (1, -36); intercepts: x = 7,-5
B. Vertex: (0,0); intercepts: x= -4,-5
C. Vertex: (7,5); intercepts: x = 7,8
D. Vertex: (1, -25); intercepts: x = 6,-4
Answer:the answer is A
Step-by-step explanation:
The vertex and x-intercepts of the graph of the function y = x²- 2x-35 is (1, -36) and intercepts: x = 7,-5, option A is correct.
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The x-coordinate of the vertex can be found using the formula x = -b/2a, where a and b are the coefficients of the x² and x terms, respectively. In this case, a = 1 and b = -2, so x = -(-2)/(2×1) = 1.
Lets find the y-coordinate of the vertex.
To find the y-coordinate of the vertex, we substitute the x-coordinate we found in step 1 into the equation and evaluate.
y = (1)² - 2(1) - 35 = -36
So the vertex is at (1, -36).
Now find the x-intercepts.
To find the x-intercepts, we set y = 0 and solve for x.
0 = x² - 2x - 35
This equation can be factored as (x - 7)(x + 5) = 0.
So the x-intercepts are at x = 7 and x = -5.
Therefore, the vertex and x-intercepts of the graph of the function y = x²- 2x-35 is (1, -36) and intercepts: x = 7,-5, option A is correct.
