Give your answer as an improper fraction in its simplest form.
Answer:
[tex]-\frac{13}{4}[/tex]
Step-by-step explanation:
r = 4x + 6y
11 = 4x + (6 x 4)
11 = 4x + 24
(im gonna flip it around because it looks better for me, you dont have to)
4x + 24 = 11 _(minus 24 from both sides)
4x = -13 _(divide both sides by 4)
x = [tex]-\frac{13}{4}[/tex]

Based on the sequence of numbers, the next two numbers in the sequence will be:
8688 = 75971 = 1What are the next numbers?The numbers on the right side of the equation are meant to show to number of circles on all the numbers on the left side.
For instance:
The number six is drawn such that it has a single circle in it = 6
The number of sixes in the first number are 3 so there will be 3 circles.
The number of circles in 8688 will be 7 because each "8" has 2 circles.
The number of circles in 5971 will be 1 because 9 is the only number drawn with a circle.

Josh mixes water and flour in the ratio 1:4. How much flour should be mixed with 2.5 cups of water?
Answer:
10 cups of flour
Step-by-step explanation:
Ratios tell you how much of one thing there are compared to another.
It is stated that the ratio of water to flour is 1:4.
This means for every 1 cup of water, there are 4 cups of flour.
If there are 2.5 cups of water, we do 2.5 x 4 = 10 cups of flour.

The height of a triangle is 2 centimeters greater than the base. The area of the triangle is 161.5 square centimeters. Find the length of the base and the height of the triangle.
Answer:
H = 19 cm
B = 17 cm
Step-by-step explanation:
A = (H x B) / 2 (formula for the area of a triangle)
161.5 = ((X + 2)(X)) / 2 (with X acting as the base)
323 = X^2 + 2X
0 = x^2 + 2x - 323
(X - 17) (X + 19) = 0
X = 17 or X = -19
You can't have a negative number as a side length so -19 doesn't work.
Because the height is larger than the base, you add the 2 to the one you will use as the height. Then just add the units (cm) because the area is in cm squared.
Learning task3:A. Change the following into the form of f(x) = mx + b
1.y-3x=7
2. 2x + 4y =8
3. -x + y =5
4.y + 5 = -2x
5. 3x + 2y - 4 = 0
Answer:
1. f(x) = 3x + 7
2. [tex]f(x) = -\dfrac12x + 2[/tex]
3. f(x) = x + 5
4. f(x) = -2x - 5
5. [tex]f(x) = -\dfrac32 x + 2[/tex]
Step-by-step explanation:
Rearrange all the equations to make y the subject,
then substitute f(x) for y:
1. y - 3x = 7
Add 3x to both sides:
⇒ y = 3x + 7
⇒ f(x) = 3x + 7
2. 2x + 4y = 8
Subtract 2x from both sides:
⇒ 4y = -2x + 8
Divide both sides by 4:
⇒ [tex]y = -\dfrac12x + 2[/tex]
⇒ [tex]f(x) = -\dfrac12x + 2[/tex]
3. -x + y = 5
Add x to both sides:
⇒ y = x + 5
⇒ f(x) = x + 5
4. y + 5 = -2x
Subtract 5 from both sides:
⇒ y = -2x - 5
⇒ f(x) = -2x - 5
5. 3x + 2y - 4 = 0
Subtract 3x from both sides:
⇒ 2y - 4 = -3x
Add 4 to both sides:
⇒ 2y = -3x + 4
Divide both sides by 2;
⇒ [tex]y = -\dfrac32 x + 2[/tex]
⇒ [tex]f(x) = -\dfrac32 x + 2[/tex]
I Need Help Please I dont understand?
Answer:
Step-by-step explanation:
One side is 9 more than the other regardless of the value of of x
This is because:
4(x+3)=3(x+1)+x
4x+12=3x+3+x
4x+12=4x+3 So the right hand side is 9 less than the left.
Since they are not equal the answer to part be is 0.
There are 0 solutions to this equation. If there were 1 or 2 solutions then the question would ask for those solutions.
Can the three numbers be the measures of the sides of a triangle? 8, 2, 8 *
Step-by-step explanation:
yes, it would be an isoceles triangle (with 2 sides being equally long).
it would be a reissue high and narrow triangle, with the very short side (2) connecting the 2 sides of 8.
in general, 3 lines can only make a triangle, if the sum of lengths of any pair of these lines is always longer than the third line.
in our case :
8+2 > 8 true
8+8 > 2 true
so, yes, they can be a triangle.
example for 3 sides not making a triangle :
2, 3, 6
as
2+3 < 6
