Answer:
x = -3
y = -2
Step-by-step explanation:
y = 2x - 4
3y = 2x
Minus bottom from top:
2y = -4
y = -2
Plug in for y to solve for x:
3y = 2x
-6 = 2x
x = -3

If there is one obtuse angle, how many angles are
acute?
a 2
b 3
C 1
d 6
Answer: a .2
Step-by-step explanation: A triangle is 180 degrees. If one angle is obtuse, it is more than 90 degrees. That leaves the two remaining angles having to add up to less than 90 degrees combined. So both have to be acute.

For a party Gary buys cheese pizzas for $5 and pepperoni pizzas for $8 each. His bill comes to $75. Let x represent the number of cheese pizzas and y represent the number of pepperoni pizzas. Write an equation to represent the situation.
Answer:
The answer is the second answer from the image. Which is 5x-8y=$75
Step-by-step explanation:
It is that answer because it costs $5 for one cheese pizza and $8 for a pepperoni pizza, so the answer is 5x-8y=75
still confused?
Its that answer because the first one and the third one are the same, just both equations like in different ways like example 10+2 is 12 right? And 2 + 10 is still 12 so that means the second answer from the image is the answer.
Hope that helps.
Answer:
the answer for this question is the first choice.
Step-by-step explanation:
first, let's figure what number represents what. we know that cheese pizzas gary bought costed him $5 and pepperoni pizzas costed him $8. since x represents cheese pizzas and y represents pepperoni pizzas, 5x and 8y should be correct. this is also said in the problem which gives the correct addends. for the operation, it tells us the bill COMES to $75. since the pizzas are COMING to $75 in total, we know that this is addition.

Ap calculus
9514 1404 393
Answer:
(c) 1.649
Step-by-step explanation:
For a lot of these summation problems it is worthwhile to learn to use a calculator or spreadsheet to do the arithmetic. Here, the ends of the intervals are 1 unit apart, so we only need to evaluate the function for integer values of x.
Almost any of these numerical integration methods involve some sort of weighted sum. For trapezoidal integration, the weights of all of the middle function values are 1. The weights of the first and last function values are 1/2. The weighted sum is multiplied by the interval width, which is 1 for this problem.
The area by trapezoidal integration is about 1.649 square units.
__
In the attached, we have shown the calculation both by computing the area of each trapezoid (f1 does that), and by creating the weighted sum of function values.

27 y + 5 = -9
Answer:
y = [tex]\frac{-14}{27}[/tex]
Step-by-step explanation:
27y + 5 = -9 -> subtract -9 and 5
(-9) - 5 = -14
27y = -14 divide 27 and -14
(-14)/27
You are then left with
y = [tex]\frac{-14}{27}[/tex]
1. Leslie visits a local department store in order to purchase summer clothes. The
price of the dress is $40. The dress is marked up 25%. What is the selling price of
the dress?
Answer:
$50
Step-by-step explanation:
Given data
We are given that the price is $40
the markup percent is 25%
Hence the price will be
40+25% of 40
=40+ 25/100*40
=40+ 0.25*40
=40+10
=$50
Therefore, the price of the dress is $50
