where do y=2x+4 and y=2.50x+2 intersect
Answer:
(4, 12)
Step-by-step explanation:
When the two lines intersect on a graph, it is when you can put the same value for "x" into both equations, and the same value for "y" into both equations.
Because they both equal "y", and y = y, you can equate the expressions together.
y = y
2x + 4 = 2.50x + 2
Now the goal is to move all the numbers with "x" to the left. Move the the numbers to the right side. (This is called isolating "x" because it will be alone).
2x + 4 - 4 = 2.50x + 2 - 4 Subtract 4 from both sides
2x = 2.50x - 2
2x - 2.50x = 2.50x - 2.50x - 2 Subtract 2.50x from both sides
-0.50x = -2
-0.50x/-0.50 = -2/-0.50 Divide both sides by -0.50
x = 4 Found "x" coordinate
Choose one of the original equations. Change "x" to 4 (called substitution).
y = 2x + 4
y = 2(4) + 4 Multiply first
y = 8 + 4 Add
y = 12 Found "y" coordinate
Now write the coordinates like an ordered pair (x, y).
The lines intersect at (4, 12).

Answer:
the answer is 2 (x-3)2
Step-by-step explanation:
Answer:
(2x + 6)(x + 3)
Step-by-step explanation:
2x^2 + 12x + 18
The above equation can be factorize as follows.
First multipy the first term(2x^2) and the last term (18) together as shown below
2x^2 x 18 = 36x^2
Next we will find the factor of 36x^2 such that the sum of the two factors will result to the second term in the equation (ie 12x). This factors are 6x and 6x. Now, let us put these factors in the equation, we have:
2x^2 +12x + 18
2x^2 + 6x + 6x + 18
Now we can factorize as follows
2x(x + 3) + 6(x + 3)
Now we have same entity in the two brackets., we'll pick one
(2x + 6)(x + 3)

The garden outside Ms.Mertz's class needs 5 liters of water a week. Jacob poured 326 millimeters of water on the garden on Monday. SEAN poured 1.5 liters of water on Tuesday. Gavin poured 2,312 ml of water on Wednesday. Stephen poured 894ml of water on Thursday. Did they pour enough water in the garden? If not, how much more water is needed?
Answer:
Enough water has been poured .
Step-by-step explanation:
The garden needed water in a week = 5 liters
Jacob poured water on Monday = 326 ml = ( 326/ 1000) liters = 0.326 liters.
SEAN poured water on Tuesday = 1.5 liters
Gavin poured water on Wednesday = 2312 ml = ( 2312/ 1000) = 2.312 liters.
Stephen poured water on Thursday = 894 ml = ( 894/ 1000) = 0.894 liters
The total amount of water poured by all these people = 0.326 + 1.5 +2.312 +0. 894 = 5.032 liters
Here we can see that water has been poured is more than the water required in a week.
After converting all the water measurements to milliliters and summing them up, the garden received 5.032 liters of water over four days, which is slightly above the required 5 liters per week. Thus, the garden received enough water.
Explanation:The question asks if the garden outside Ms. Mertz's class received enough water over a week. To determine this, we need to add up the amounts of water poured each day and compare it to the required 5 liters per week.
Jacob poured 326 milliliters (ml) on Monday.SEAN poured 1.5 liters (l), which is 1500 ml, on Tuesday.Gavin poured 2,312 ml on Wednesday.Stephen poured 894 ml on Thursday.First, we convert all measurements to the same unit (milliliters). Then we sum up all the amounts:
326 ml (Monday) + 1500 ml (Tuesday) + 2312 ml (Wednesday) + 894 ml (Thursday) = 5032 ml
Since 1 liter = 1000 milliliters, we divide 5032 ml by 1000 to convert to liters:
5032 ml = 5.032 liters
The garden received 5.032 liters over the four days, which is just above the required 5 liters of water per week.
Therefore, the garden has received enough water for the week, with a small excess of 32 ml.

If the length of each side of a triangle is cut to 1/3 of its original size, what happens to the area of the triangle?
Answer:
The new area of the triangle is (1 / 9) th of the original area.
That is to say the original area of the triangle is decreased to (1/9) th of its value.
Step-by-step explanation:
The area of a triangle is given by, Area = 1/2 [tex]\times[/tex] base [tex]\times[/tex] height
If each side of a triangle is cut to 1/3 of its original size then the base will also become one third and the height will also become one third.
Therefore the new area will be given by = 1/2 [tex]\times[/tex] (1/3 [tex]\times[/tex] base) [tex]\times[/tex] (1/3 [tex]\times[/tex] height)
= 1/9 [tex]\times[/tex] 1/2 [tex]\times[/tex] base [tex]\times[/tex] height
= 1/9 [tex]\times[/tex] Area.
The new area of the triangle is 1 / 9 th of the original area.
When the sides of a triangle are reduced to 1/3 of their original size, the area of the triangle becomes 1/9 of its original area.
When the length of each side of a triangle is cut to 1/3 of its original size, the area of the triangle is affected by the square of the scale factor applied to the sides.
Let's use some mathematics to understand why this happens. The area of a triangle is given by the formula:
A = 1/2 * base * height, where 'base' represents the base of the triangle and 'height' represents the height of the triangle.
If each side of the triangle is reduced to 1/3 of its original size, both the base and the height will become 1/3 of their respective original sizes.
The new area (A') can be calculated as follows:
New base = 1/3 of original baseNew height = 1/3 of original heightA' = 1/2 * (1/3 * base) * (1/3 * height)Simplifying this:
A' = 1/2 * (base * height) * (1/3 * 1/3)
A' = 1/2 * base * height * 1/9
A' = (1/2 * base * height) * 1/9
A' = A * 1/9
Therefore, the area of the triangle becomes 1/9 of its original area.

Someone bought a watermelon pack of napkins and a paper plate the food do not have tags but the non-food items have 5% tax the total cost before tax was $8.25 the tax was $.19 how much was the watermelon
Question:
A shopper bought a watermelon, a pack of napkins, and some paper plates. In his state, there is no tax on food. The tax rate on non-food items is 5%. The total for the three items he bought was $8.25 before tax, and he paid $0.19 in tax. How much did the watermelon cost?
Answer:
Cost of watermelon is $ 4.45
Solution:
From given,
Total amount for three items before tax = $ 8.25
Tax amount = $ 0.19
Tax on non food = 5 %
Here, non food means napkin and paper plates
Let "x" be the cost spent for napkin and paper plates
Then,
5 % = 0.19
100 % = x
This forms a proportion
[tex]5 \times x = 0.19 \times 100\\\\5x = 19\\\\x = 3.8[/tex]
Thus cost spent for napkin and paper plates is $ 3.8
Therefore,
Watermelon cost = total amount before tax - cost spent for napkin and paper plates
Watermelon cost = 8.25 - 3.8 = 4.45
Thus cost of watermelon is $ 4.45
The watermelon cost $4.45, calculated by subtracting the cost of the non-food items ($3.80) taxed at 5% from the total cost before tax ($8.25).
The information provided gives us the total cost before tax ($8.25) and the total tax amount ($0.19). Because only non-food items are taxed, and the tax rate is 5%, we can find the cost of the non-food items by dividing the total tax amount by the tax rate (expressed as a decimal).
Convert tax rate to decimal: 5% = 0.05
Divide the total tax by the tax rate: $0.19 / 0.05 = $3.80
Deduct the cost of the non-food items from the total cost before tax: $8.25 - $3.80 = $4.45
The cost of the watermelon, which is a food item and thus not taxed, is $4.45.

Combine 2y+1x=40 and y=2x using substitution
2(2x) + 1x = 40 or 4x + 1x = 40 is the result of combining by substitution
Solution:
Given that we have to combine 2y + 1x = 40 and y = 2x using substitution method
The substitution method for solving systems of equations involves expressing one variable in terms of another, thus removing one variable from an equation.
Given equations are:
2y + 1x = 40 -------- eqn 1
y = 2x ----------- eqn 2
We can substitute eqn 2 in eqn 1
Which means, substitute y = 2x in place of y in eqn 1
2(2x) + 1x = 40
4x + 1x = 40
5x = 40
x = 8
From eqn 2,
y = 2(8)
y = 16
Thus by combining using substitution method we found the solution

The base of a triangle is 5 times the height. If the area is 490 square feet, then what is the height of the triangle, in feet?
Answer: 14 feet
Step-by-step explanation:
The formula for finding the area of a triangle is given as :
Area = [tex]\frac{1}{2}[/tex] x base x height
Let the height be h , then the base is 5 times the height , that is the base is 5h.
Substituting into the formula , we have
490 = [tex]\frac{1}{2}[/tex] x h x 5h
490 = [tex]\frac{1}{2}[/tex] x [tex]5h^{2}[/tex]
multiply through by 2
980 = [tex]5h^{2}[/tex]
divide through by 5
196 = [tex]h^{2}[/tex]
Therefore :
h = 14
Therefore : the height is 14 feet
