Write an equation in slope-intercept form that goes through the points (-3, -4) and (3,4).
Answer:
Y = 4/3x + 0
Step-by-step explanation:
(-3,-4) and (3,4) can be plugged in to rise over run.
y 4 -(-4) = 8
x 3 - (-3) = 6
8/6 = 4/3
Plug into slope intercept form
4 = 4/3(3) + b
4 = 12/3 +b
4 = 4 +b
Subtract from both sides
0 = b
Y = 4/3x + 0
The equation in slope intercept form that goes through the points (-3,-4) and (3,4) is [tex]y=\frac{8}{6}x[/tex]
What is Slope of the line?The slope of a line gives the measure of its steepness and direction.
What is the Slope intercept form?The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept.
Given,
Slope of the line passing through the points (-3,-4) and (3,4)
Slope of the line m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}=\frac{4+4}{3+3}=\frac{8}{6}[/tex]
Therefore slope of the line is [tex]\frac{8}{6}[/tex]
Find the y intercept using the slope and the point (-3,-4)
y=mx + b
-4 = [tex]\frac{8}{6}[/tex]×-3 + b
-4 =-4+b
b=-4+4 =0
Then,
The equation in slope intercept form is
y = mx + b
y = [tex]\frac{8}{6}[/tex]x + 0
[tex]y=\frac{8}{6}x[/tex]
Hence, the equation in slope intercept form that goes through the points (-3,-4) and (3,4) is [tex]y=\frac{8}{6}x[/tex]

What is the volume of the prism?
ft3
1
12 ft
6 ft
8 ft
V=lwh
V=8×12×6=576 ft³
Answer: V=576 ft³
The volume of the prism is calculated by multiplying the length, width, and height, resulting in 576 cubic feet.
To calculate the volume of the prism, we have to use the formula for the volume of a rectangular prism, which is length times width times height. Given the dimensions of the prism as 12 feet in length, 6 feet in width, and 8 feet in height, the volume is calculated as follows:
Multiply the length by the width: 12 ft times 6 ft = 72 ft².Multiply the result by the height: 72 ft² times 8 ft = 576 ft³.Therefore, the volume of the prism is 576 cubic feet (ft³).

If x = 2 and y=-3, then -xy^2 =
A) -36
B) 18
C) -12
D) - 18
Answer:
-18
Step-by-step explanation:
-xy^2 =
Let x=2 and y = -3
-(2) (-3)^2
-2 (9)
-18
If x = 2 and y=-3, then -xy² B) 18.
To solve the given mathematical problem, we will substitute the given values of x and y into the expression and calculate the result step by step.
Given:
x = 2
y = -3
We need to calculate the value of the expression:
[tex]-xy^2[/tex]
Substitute the given values into the expression:
[tex]-xy^2 = -(2)(-3)^2[/tex]
Now, calculate the square of y:
[tex](-3)^2 = 9[/tex]
Next, multiply the values together:
[tex]-xy^2 = -(2)(9)[/tex]
[tex]-xy^2 = -18[/tex]
Since there is a negative sign outside the parentheses, the result will be the negative of the product inside:
[tex]-xy^2 = 18[/tex]
Therefore, the final answer is 18.
Below is the graph of a trigonometric function. It has a maximum point at (-5pi/4,6.7) and an amplitude
of 4.1. What is the midline of the function? Y=____
We have been given that the maximum point at the graph of a trigonometric function is [tex](-\frac{5\pi}{4},6.7)[/tex] and amplitude of the function is 4.1. We are asked to find the mid-line of the given function.
We will use mid-line formula to solve our given problem.
[tex]\text{Mid-line value}=\text{Maximum value}-\text{Amplitude}[/tex]
Upon substituting our given values in above formula, we will get:
[tex]\text{Mid-line value}=6.7-4.1[/tex]
[tex]\text{Mid-line value}=2.6[/tex]
Therefore, the mid-line of the given function would be [tex]y=2.6[/tex].
The function f(x) = −x2 + 60x − 116 models the monthly profit, in dollars, a shop makes for repairing windshields, where x is the number of windshields repaired. Determine the vertex, and explain what it means in the context of the problem. (30, 784); The vertex represents the maximum profit.
(30, 784); The vertex represents the minimum profit.
(2, 58); The vertex represents the maximum profit.
(2, 58); The vertex represents the minimum profit.
Answer:
Even tho the answer is not up there but its
(30, 784); The vertex represents the maximum profit.
Step-by-step explanation:
....
For the quadratic equation f(x) = -x^2 + 60x - 116, the vertex is (30, 784), and it is a maximum.
How to get the vertex?
For a general quadratic equation:
y = a*x^2 + b*x + c
The vertex is at the x-value:
h = -b/2a
To get the y-value, we evaluate the quadratic equation in h.
In our case, we have:
y = -x^2 + 60x - 116
Then:
h = -60/(2*-1) = 30
To get the y-value of the vertex, we evaluate in x = 30.
y = -(30)^2 + 60*30 - 116 = 784
And, as you can see, the leading coefficient of the quadratic equation is negative. This means that the arms open downwards, so the vertex is a maximum.
Then, concluding, the vertex is (30, 784), and it is a maximum.

Tell whether the ordered pair is a solution of the system of equations.
(2.1)
2x+y=5
y = 4x– 1
1. No, (2,1) is a solution for y = 4x – 1 but not for 2x + y = 5.
2. Yes, (2,1) is a solution for both equations
3. No, (2,1) is a solution for 2x + y = 5 but not for y = 4x - 1
Answer:
2x + y = 5
y = 4x – 1
Substitute (2, 1) into system, then:
2x + y = 5 => 2 x 2 + 1 = 5 => 5 = 5 (satisfied)
y = 4x– 1 => 4 x 2 - 1 = 1 => -7 = 1 (not satisfied)
=> Option 3 is correct.

Answer:
56
Step-by-step explanation:
By adding the other two angles you can calculate the missing angles. And since they are the same angles they are the same measure. Add the two angles provided and then subtract that from 180 and you get your answer.
:)
Answer:
∠1=56°
∠2=56°
∠3=74°
Step-by-step explanation:
Degrees in a triangle is 180°
180°-(66°+58°)=∠1
180°-124°=∠1
∠1=56°
∠1=∠2- Vertical angles
∠1=56°
∠1=∠2
∠2=56°
∠3=180°-(56°+50°)
∠3=180°-106°
∠3=74°
In the figure above, angles are as marked. The angle labeled with a measure of bº is an exterior angle. What is the measure of b?
Answer:
105
Step-by-step explanation:
First, solve for a
2a-15+2a+15+3a-5+a+5=360(Sum of interior angles of quadrilateral is 1360)
8a=360
a=360/8
a=45
Now,Look at the angles formed in straight line
b+2a-15=180(Sum of angles formed in a straight line is 180)
b+2×45=180+15
b=195-90
b=105

Answer:
The possible dimensions of the container are
- 10 in, by 12 in. by 24 in
- 12 in. by 12 in. by 20 in
Step-by-step explanation:
Given
Volume of the container = 2,880 cubic inches
Required
Possible dimensions of the container
To solve this question, the following assumption has to be made;
It'll be assumed that the container is a rectangular
To calculate the volume of a rectangular figure, we simply multiply the dimensions of the figure,
This implies that; we'll test each of the given options.
Which ever gives 2,880 is the right answer.
- 10 in, by 12 in. by 24 in.
[tex]Volume = 10 in * 12 in * 24 in[/tex]
[tex]Volume = 2,880[/tex] cubic inches
- 12 in. by 15 in. by 18-in.
[tex]Volume = 12 in * 15 in * 18 in[/tex]
[tex]Volume = 3,240[/tex] cubic inches
- 10 in. by 16 in. by 20 in.
[tex]Volume = 10 in * 16 in * 20 in[/tex]
[tex]Volume = 3,200[/tex] cubic inches
- 12 in. by 12 in. by 20 in.
[tex]Volume = 12 in * 12 in * 20 in[/tex]
[tex]Volume = 2,880[/tex] cubic inches
From the calculation above, only option A and D gives 2,880;
Hence, the possible dimensions of the container are
- 10 in, by 12 in. by 24 in
- 12 in. by 12 in. by 20 in
Given a volume of 2,880 cubic inches, one possible set of dimensions for a shipping container could be length = 24 inches, width = 15 inches, and height = 8 inches.
The volume of a rectangular container can be calculated by multiplying its length, width, and height. Given the volume of 2,880 cubic inches, we are looking for three numbers (dimensions) that, when multiplied together, equal 2,880.
One possible set of dimensions could be length = 24 inches, width = 15 inches, and height = 8 inches. Multiplying these dimensions together: 24 inches × 15 inches × 8 inches = 2,880 cubic inches, which matches the given volume of the container.
