what is the slope of the line with the following equation? (y-3)= -4(x-5)
Answer:
slope = - 4
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = - 4(x - 5) ← is in point- slope form
with slope m = - 4
Answer:
-4
Step-by-step explanation:
First express it in the form of y=mx+b where m is the slope and b is the y-intercept
y-3=-4x+20
y=-4x+20+3
y=-4x+23 then m=-4 which is the slope

A basket of fruit holds 12 apples, 24 pears, and 16 oranges. Find the ratio of apples, pears, and oranges in the basket.
Answer:
3:6:4
Step-by-step explanation:
We are given that
Number of apples in the basket=12
Number of pears in the basket=24
Number of oranges in the basket=16
We have to find the ratio of apples, pears and oranges in the basket.
[tex]12=4\times 3[/tex]
[tex]24=4\times 3\times 2[/tex]
[tex]16=4\times 2\times 2[/tex]
HCF (12,24,16)=4
Now, divide each number by HCF
Then, we get
3:6:4
Therefore, the ratio of apples, pears and oranges in the basket.
3:6:4

bob is twice as old as ralph. three years ago the sum of their ages was 45. what are their ages now?
answer using a let statement
Answer:
Were they both 45? I'm kinda confused on that part, but I think Ralph would be 48 and Bob would be 50
Step-by-step explanation:
Answer:
34 and 17
Step-by-step explanation:
Bob = B
Ralph = R
B=2R
B-3+R-3=45
B+R-6=45
+6 +6
B+R=51
Substitute B for 2R
2R+R=51
3R=51
R=17
2(17)=34
so B is 34 and R is 17

Step-by-step explanation:
When you solve it out, you know that vertical angles are congruent. So the top angle is 42. Then you need to find out the angle adjacent to the 87. This is a supplementary angle. Supplementary angles add up to 180. So, 180 - 87 = x. This comes out to 93. Then you just need to find ?. All angles in a triangle add up to 180. So 180 - 93 -42 = 45. ? = 45
For this one we know that the angles in a triangle add up to 180. So, 180 - 35 - 70 = 75. Vertical angles are congruent so ? is also equal to 75.
For this one, we know supplementary angles add up to 180. We use this for every angle. 180 - 145 = 35. 180 - 105 = 75. Angles in a triangle add up to 180 so, 180 - 75 - 35 = 70. We know the other angle in the triangle, we now need to find the angle that is supplementary. We know they add up to 180 so, 180 - 70 = 110. ? = 110
We know 2 of the angles, 90 and 60. We can solve for the third angle. 180 - 90 - 60 = 30. Vertical angles are congruent so ? also equals 30.
We now 2 angles. 60 and 70. We can find the third angle. 180 - 60 -70 = 50. We now need to solve for x. We can subtract 14 from 50 then divide it by 3. We get 12. X is = 12.
We know 2 angles. 65 and 90. This means the third angle is 25. We need to solve for x so 25 - 1 = 24. Then divide that by 6. We get 4. X = 4.
We know 2 angles. 70 and 70. This means the third angle is 40. We can divide that by 8 to find x. X = 5.
We know 2 angles. 70 and 90. This means the third angle is 20. We can subtract 2 to get 18. Then divide by 2. We get 9. X = 9.
We first need to find the last angle in the first triangle. 180 - 85 - 50. The third angle is 45. We now know 2 angles in the second triangle. We can now solve for ?. 180 - 75 - 45. ? = 60
We first need to find the last angle in the first triangle. 180 - 70 - 70. 40 is the last angle. We now have 180 - 40 - 80. It comes out to 60. ? = 60.

What is the area of the regular hexagon ABCDEF? Explain your reasoning.
Answer:
2340 units²
Step-by-step explanation:
The easiest way to solve for the area of the hexagon is to find the area of the rectangle and subtracting the area of the triangles from it.
First, find the area of the rectangle:
A(rectangle) = (15 + 30 + 15)(26 + 26)
A(rectangle) = (60)(52)
A(rectangle) = 3120
Next, find the area of the 4 triangles:
A(triangles) = 1/2(15)(26) · 4
A(triangles) = 195 · 4
A(triangles) = 780
Finally, subtract the two areas to find the area of the hexagon:
A(hexagon) = 3120 - 780
A(hexagon) = 2340
Based on the information given the area of hexagon is 2340.
Area of hexagon:First step is to find the area of the rectangle:
Area of rectangle= (15 + 30 + 15)(26 + 26)
Area of rectangle=60×52
Area of rectangle= 3120
Second step is to find the area of the 4 triangles:
Area of rectangle =[1/2(15)(26)]×4
Area of rectangle= 195 × 4
Area of rectangle= 780
Third step is to find the area of hexagon:
Area of hexagon= 3120 - 780
Area of hexagon=2340
Inconclusion the area of hexagon is 2340.

What is a system of equations?A finite collection of equations for which we searched for common solutions is referred to in mathematics as a system of equations, sometimes known as a set of simultaneous equations or an equation system. Similar to single equations, a system of equations can be categorized.
A linear equation can only have one unique solution, which is a location at which the LHS and RHS of the equation are equal. There is only ever one solution to a linear equation with one variable.
y = 5x - 1
y = 3x + 7
5x - 1 = 3x + 7
2x = 8
x = 4
y = 19
Therefore, there will be one unique solution of the equation y = 5x - 1 and y = 3x + 7.
