Answer:
False
Step-by-step explanation:
plug -2 in for x. 3(-3)-4=-10 and -10 isn't 10 so false.
(can I get brainliest please)
Answer:
False
Step-by-step explanation:
f(x) = 3x-4
f(-2) = ?
Substitute -2 for x in the given equation
f(-2) = 3(-2)-4
f(-2) = -6-4
f(-2) = -10
-10= 10
FALSE
Use the order of operations to evaluate this expression: 7 + (5 – 9)2 + 3(16 ÷ 8).
Answer:
= 7 + (5 – 9)2 + 3(16 ÷ 8)
= 7 + (-4)2 + 3(2)
= 7 + (-8) + 6
= -1 + 6
= 5

I NEED BOTH PARTS!
Answer:
a) Yes agree
and b) (I'm not too sure about this one but I think..) By CPCT that is Corresponding parts of congruent triangles are equal/congruent theorem.
Step-by-step explanation:
I'll use this " [ " symbol for angle.
a) yes agreed ;
AB = CB (B is the midpoint of AC)
[ ABD = [ CBD = 90°
BD = BD (common side)
--> therefore by SAS criteria triangle ABD is congruent to triangle CBD.
and by CPCT .... AD = CD .
b) AD = CD (proven by CPCT)
...answer for b you're likely suppose to write it that way. so yeah hope this helps.

A store is instructed by corporate headquarters to put a markup of 25% on all items. An item costing 8$ is displayed by the store manager at a selling price of 2$. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Answer:
the correct selling price is $10
And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price
Step-by-step explanation:
The computation is shown below:
Given that
Markup = 25%
Cost of an item = $8
Selling price of an item = $2
Based on the above information
The amount of markup would be
= 25% × 8%
= $2
Now amount after markup is
= $2 + $8
= $10
Hence, the correct selling price is $10
And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price
Answer:
part A:The correct selling price is $10
Part B:And, the error is that the manager put the markup percentage as a selling price instead of adding up the markup to the cost price

The length of a rectangle is 5 less than 3 times its width. The perimeter is
78. Find the LENGTH.*
Answer:
The length is 28 and the width is 11
Step-by-step explanation:
To solve this problem, we can make the width as x.
Since the length is 5 less than 3 times the width, it's going to be 3x - 5
So now we've got the length and width, just need to find the perimeter, which is all the sides added up together. They already gave us the perimeter, so we just have to solve the equation:
2(3x - 5) + 2x = 78
6x - 10 + 2x = 78
8x - 10 = 78
8x = 88
x = 11
x = 11, but remember, x is the width, not the length. Since we already found what x is, we just have to plug it into the equation of:
3x - 5
3 × 11 - 5
33 - 5 = 28
Answer: Length = 28 (don't forget to add the unit if there is one)

9514 1404 393
Answer:
1. multiply both sides by 3
2. (a) chose to multiply by 2/3 instead of 3/2; (b) did the multiplications incorrectly, both for the fraction and the integer; (c) x = 9
Step-by-step explanation:
1. If you want to "clear fractions," you multiply by the denominator of the fraction.
3(2/3)x = 3(6)
2x = 18
__
2. The coefficient of x is 2/3. If you want it to be 1, you need to multiply by the multiplicative inverse of 2/3, which is 3/2. Doing that gives ...
(3/2)(2/3)x = (3/2)6
Then simplifying gives ...
x = 18/2 = 9
__
Trey's mistakes were: a) choosing the wrong multiplier; b) carrying out the multiplication incorrectly. (2/3)(2/3) = 4/9, and 6(2/3) = 4. Had Trey done the multiplications correctly, he would have seen that he needed a different multiplier to get to the answer.

Step-by-step explanation:
Lamar drinks 8 ounces of water with breakfast, 6 ounces of water with his vitamins, 16 ounces of water with his lunch, 16 ounces of water with his dinner, and 32 ounces of water from a bottle he carries throughout the day. Write and evaluate a numerical expression for the amount of water in ounces that he drinks in a week.
Given:
Lamar drinks water with,
Breakfast = 8 ounces
Vitamins = 6 ounces
Lunch = 16 ounces
Dinner = 16 ounces
Bottle = 32 ounces
To find:
The a numerical expression for the amount of water in ounces that he drinks in a week.
Solution:
One day consumption of water by Lamar is
[tex]8+6+16+16+32=78[/tex]
We know that,
1 week = 7 days
One day consumption of water = 78 ounces
1 week (7 days) consumption of water = 7× One day consumption of water
= 7×(8+6+16+16+32) ounces
= 7×78 ounces
= 546 ounces
Therefore, the required numerical expression for the amount of water in ounces that he drinks in a week is 7×(8+6+16+16+32) ounces and the value is 546 ounces.

Raja claims that to add two fractions with unlike denominators, first you need to determine the smallest number that is a multiple of both denominators. Then change the denominators in both fractions and keep the numerators the same.
Answer:
Incorrect
Step-by-step explanation:
This is incorrect. In order to add two fractions that have unlike denominators, it is true that you first need to find a common denominator. When you change a fractions denominator you must also change it's numerator in proportion to the change in the denominator. For example, if you change the denominator in the fraction [tex]\frac{1}{2}[/tex] into a 4 then you are multiplying the denominator by 2, therefore you will also need to multiply the numerator by 2 which would give you a new fraction of [tex]\frac{2}{4}[/tex]

When you find a point on a graph that you think is the intersection, the best way to double check your answer is to:
substitute in the x value to see if both of the y values of both of the equations match the one you approximated from the graph.
substitute in the x value to see if one of the y values of one of the equations matches the one you approximated from the graph.
substitute in the y value to see if one of the x values of one of the equations matches the one you approximated from the graph.
substitute in the x value to see if both of the x values of both of the equations match the one you approximated from the graph.
Answer: Substitute in the x value to see if both of the y values of both of the equations match the one you approximated from the graph.
Step-by-step explanation:
I guess that we are working with systems of equations like:
y = f(x)
y = g(x)
Where an intersection is a solution that works for both equations, which means that the graphs will intersect each other in that point.
This means that for a given value x = x0, we must have:
f(x0) = g(x0).
Now, when you find a point that you think that is an intersection, you should substitute the x value in both functions, and see if the y-values coincide.
This will be equivalent to look if f(x) = g(x) for that particular value.
then the correct option is:
substitute in the x value to see if both of the y values of both of the equations match the one you approximated from the graph.
