Answer:
x=4 and y=0
Step-by-step explanation: To solve, solve for x and y by substituting for the opposite intercept. For y, substitute x for 0 (since the coordinates for the x-int are always 0). Do the same for x.

The company estimated that they would sell 500 caps during the football season. They actually sold 575. Find the percent error. Round to the nearest tenth. I need this one fast
Answer:
13.1%
Step-by-step explanation:
The company estimated that there would be 500 a ps during the football season
The actually sold 575
Therefore the percent error can be calculated as follows
= 575-500/575 × 100
= 75/575 × 100
= 0.1304×100
= 13.1%
Hence the percent error is 13.1%

The triangle is isosceles
Equal sides have length of
5x - 11 = 3x - 35x - 2x = 11 - 33x = 9x = 313. ..................................................
The triangle is isosceles
x is one of the angles of a right triangle
The other angle of this triangle is same as corresponding angle = 63°
x = 90° - 63° x = 27°Answer:
11. x = 413. x = 27°Step-by-step explanation:
11. isosceles triangle with two equal side lengths
5x - 11 = 3x - 3
5x - 3x = 11 - 3
2x = 8
x = 8 / 2
x = 4
13. isosceles triangle mirrored right triangle
with angles 63°, 90° and x , find x
90 + 63 + x
90 - 63 = x
x = 27°
Riley is placing the game board shown on his bedroom wall. What area of the wall will the game board cover? Use 3.14 for π and round to the nearest whole square foot. I will give brainliest.
Answer:
The answer is 5 ft squared
Step-by-step explanation:
so you have the find the area of the circle first and you do that by starting with the formula which is
pi r2
the diameter is 2.45 so you divide that by to to get the radius and get 1.25
the you would multiply 1.25 times 1.25 times 3.14, and get 4.91 which rounds to by the nearest whole umber as 5 ft 2.

What is the product in the expression 30m= n+58?
Answer: m=1/30n+29/15
Step-by-step explanation:
Answer:
if solving for m it is m= n+58/30
if solving for n it is n= 30m-58
Step-by-step explanation:
for m- divide both sides by 30 but keep it in fraction form for n+58
for n- subtract 58 from both sides to make it n=30m-58

If 49-X = 2, what does 7X equal?
Answer:
7x = 42
Step-by-step explanation:
This equation can be solved by isolating the variable.
Explanation:
To solve an equation like this, the first step is to isolate the variable. This means that we need to get x on one side of the equal sign by itself. This is the only way we can solve for x.
In this case, we isolate x by dividing both sides by seven.
Answer:
329Step-by-step explanation:
49 - X = 2
find: 7X
49 - X = 2
49 - 2 = X
X = 47
substitute X=47 into 7X
7X7 (47)329therefore, 7X = 329

Given f(x) = -3x + 5, solve for x when f(x) =
- 4.
Answer:
x = 3
Step-by-step explanation:
Step 1: Define
f(x) = -3x + 5
f(x) = -4
Step 2: Substitute and Evaluate
-4 = -3x + 5
-9 = -3x
x = 3
Answer:
3 =x
Step-by-step explanation:
f(x) = -3x + 5
Let f(x) = -4
-4 = -3x+5
Subtract 5 from each side
-4-5 = -3x+5-5
-9 = -3x
Divide each side by -3
-9/-3 = -3x/-3
3 =x

Step-by-step explanation:
On a coordinate plane, a straight line with a positive slope begins at point (0, 50) and ends at point (5.5, 600).
Which scenario is most likely the one shown on the graph?
the total amount of money in the cash register, y, containing $50 in change and small bills and x $100 bills
the total number of puzzle pieces, y, in a brand new 50-piece puzzle, and x brand-new 100-piece puzzles
the total weight of the barbell, y, where the bar weighs 50 pounds and x 100-pound weights are added to it
the total number of calories, y, in a salad with vegetables containing 50 calories topped with x ounces of salad dressing at 100 calories per ounc
The correct answer is option D, "The total Number of calories, y, in a salad with vegetables containing 50 calories topped with x ounces of salad dressing at 100 calories per ounce."
Given that a straight line with a positive slope begins at point (0,50) and ends at point (5.5,600), we are required to identify which of the given scenarios is most likely shown on the graph. We will discuss each scenario and determine which one matches the given line on the coordinate plane.
Let us discuss each scenario one by one:
Scenario 1: The total amount of money in the cash register, y, containing $50 in change and small bills and x $100 bills.In this scenario, there are two variables - x and y, where x is the number of $100 bills in the cash register, and y is the total amount of money in the cash register. The initial value of y is $50 since it is already in the cash register.
However, we don't know the value of x. Therefore, we cannot form a linear equation using the two variables. Moreover, the graph of the equation will be a straight line, which will not match the given line on the coordinate plane. Therefore, this scenario is not the one shown on the graph.
Scenario 2: The total number of puzzle pieces, y, in a brand new 50-piece puzzle, and x brand-new 100-piece puzzles.In this scenario, there are two variables - x and y, where x is the number of 100-piece puzzles, and y is the total number of puzzle pieces. Again, we don't know the value of x.
Therefore, we cannot form a linear equation using the two variables. Moreover, the graph of the equation will be a straight line, which will not match the given line on the coordinate plane. Therefore, this scenario is not the one shown on the graph
.Scenario 3: The total weight of the barbell, y, where the bar weighs 50 pounds and x 100-pound weights are added to it.In this scenario, there are two variables - x and y, where x is the number of 100-pound weights added to the bar, and y is the total weight of the barbell. The initial value of y is 50 pounds, which is the weight of the barbell. However, we don't know the value of x. Therefore, we cannot form a linear equation using the two variables. Moreover, the graph of the equation will be a straight line, which will not match the given line on the coordinate plane. Therefore, this scenario is not the one shown on the graph.
Scenario 4: The total number of calories, y, in a salad with vegetables containing 50 calories topped with x ounces of salad dressing at 100 calories per ounce. In this scenario, there are two variables - x and y, where x is the number of ounces of salad dressing, and y is the total number of calories in the salad. The initial value of y is 50 calories, which is the calorie content of the vegetables.
The calorie content of salad dressing is given as 100 calories per ounce. Therefore, the equation that relates x and y is:y = 100x + 50This is a linear equation in two variables, and the graph of this equation will be a straight line. Let us verify if this equation matches the given line on the coordinate plane.
Using the two given points on the line, we can find the slope of the line. The slope of the line is given by:m = (y2 - y1) / (x2 - x1)m = (600 - 50) / (5.5 - 0)m = 550 / 5.5m = 100
Therefore, the equation of the line is:y - 50 = 100(x - 0)y = 100x + 50This is the same equation as we obtained earlier. Hence, we can conclude that this scenario is the one shown on the graph.
Therefore, the correct answer is option D, "The total number of calories, y, in a salad with vegetables containing 50 calories topped with x ounces of salad dressing at 100 calories per ounce."

4(4 -8n) -7n = -30 + 7n
Answer:
n=1
Step-by-step explanation:
Use the distributive property to multiply 4 by 4−8n.
16−32n−7n=−30+7n
Combine −32n and −7n to get −39n.
16−39n=−30+7n
Subtract 7n from both sides.
16−39n−7n=−30
Combine −39n and −7n to get −46n.
16−46n=−30
Subtract 16 from both sides.
−46n=−30−16
Subtract 16 from −30 to get −46.
−46n=−46
Divide both sides by −46.
n=−46/−46
Divide −46 by −46 to get 1.
n=1
Answer: n = 1
Step-by-step explanation:
Using the distributive law, multiply 4 by what's in the bracket.
(4)(4) -(8n)(4) -7n = -30 + 7n
16 -32n -7n = -30 + 7n
Group all like terms together. Once a (+ve) number goes over the equal sign it now becomes a (-ve) number, vise versa.
16 +30 = 32n + 7n + 7n
46 = 46n
Now we need to find for n. 46n can also be written as 46 multiply by n. When a multiplication sign goes over the equal sign, the sign changes to a division sign.
46 = 46n
46/46 = n
1 = n
