3x + y = -4
3x - 4y = 6
Answer:
(-1, -2) or x=-1 y=-2
Step-by-step explanation:
3x+y=-4 (1)
3x-4y=6 (2)
i used the first equation to subtract the second this cancels out the x
and you are left with:
5y=-10
y=-2
plug this back in:
2x+(-2)=-4
2x-2=-4
add 2 to both sides:
2x=-2
x=-1
Mrs.Smith stacked 6 cubes on top of one another to make a tower. If the tower is sitting on the floor, how manyof the cubes faces can Mrs.Smith see?
Answer: 25 faces
Step-by-step explanation:
Given
6 cubes are stacked over each other
Mr. Smith wants to count the number of faces
The faces which are in contact with each other are not visible to Mr. smith i.e. there will be 5 cubes with only 4 faces available and only one cube with 5 faces available, that is placed on the top.
No of visible faces
[tex]\Rightarrow 4\times 6+1\quad \quad [\text{6 cubes with 4 faces visible+face of top cube}]\\\Rightarrow 25\ \text{faces}[/tex]

A cylinder has a height of 7 yards and a radius of 14 yards. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
The answer to the nearest hundredth, the volume of the cylinder is approximately 4309.28 cubic yards.
To calculate the volume of a cylinder, we can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height.
Radius (r) = 14 yards
Height (h) = 7 yards
Approximation of π = 3.14
Substituting these values into the formula, we have:
[tex]V = 3.14 \times(14^{2} )\times 7[/tex]
First, let's calculate the value of (14²):
[tex]14^{2} = 14 \times 14 = 196[/tex]
Now, substitute the values back into the formula:
[tex]V = 3.14 \times 196 \times 7[/tex]
Next, perform the calculations:
[tex]V = 3.14 \times 1372[/tex]
V ≈ 4309.28

What is the slope of AB?
Can anyone help me ??
Answer:
1/2
Step-by-step explanation:
Point A is (2, 3)
Point B is (6, 5)
To get the slope of a line, first select any two points on that line.
Then, take the difference of the y values, and divide it by the difference of the x values. This is also known as the change in y over the change in x, or rise over run.
[tex]\frac{3-5}{2-6} =\frac{-2}{-4} =\frac{1}{2}[/tex]
1/2 is the slope.

Which equation represents the line with slope – 2 that
passes through the point (-4, -5)?
Answer:
D. y+5 = -2(x+4)
Step-by-step explanation:
[tex] \large \boxed{y - y_1 = m(x - x_1)}[/tex]
The equation above is point-slope form where x1 and y1 both are the point that the graph passes through ane m is slope as usual.
We are given the point (-4,-5) and slope of -2. We substitute these values in.

Answer:
m(DE) = 90°
Step-by-step explanation:
Since both circles are equal, therefore, their radius would be equal too.
m<S = 180 - right angle (angles on a straight line)
m<S = 180 - 90 = 90°
m<R = m<S (congruent triangles)
m<R = 90°
m<R = m(DE) (central angle = intercepted arc based on the central angle theorem)
Substitute
90° = m(DE)
m(DE) = 90°
Spinner A and Spinner B have 4 color choices each: grey, orange, blue and yellow. What is the probability of getting a Blue and Grey combination from the area model below?
Answer:
The probability of getting a Blue and Gray combination is 6.25%.
Step-by-step explanation:
Given that Spinner A and Spinner B have 4 color choices each: gray, orange, blue and yellow, to determine what is the probability of getting a Blue and Gray combination from the area model below, the following calculation must be performed:
Blue / Total: 1/4
Gray / Total: 1/4
1/4 = 0.25
0.25 x 0.25 = X
0.0625 = X
0.0625 x 100 = 6.25
Therefore, the probability of getting a Blue and Gray combination is 6.25%.
