Answer:
(2, 1): Yes
Step-by-step explanation:
5x - 3y = 7
-2x + 7y = 3
(2, 1) = 5(2) - 3(1) = 7
10 - 3 = 7
7 = 7
-2(2) + 7(1) = 3
-4 + 7 = 3
3 = 3

Graphing Absolute Value Functions & Inequalities
f (x) = |3x-4|
Answer:
absolute value makes everything positive instead of negative so since you didn't even really ask a question I'm just going to solve the problem without a point
f(x)=3x+4
f(x) = 3x - 4
f'(x) = x
x = 0
et
3x - 4 = 0
3x = 4
x = 4/3
3 * 0 - 4 = 0 - 4 = - 4
3 * 4/3 - 4 = 0
f(x) = I3x - 4I = I-4 ; 0I
how to use side lengths to determine the type of triangle.
Answer:
I think this is how you use it.
Use the side lengths to classify the triangle as acute, right, or obtuse. Classify the triangle as acute, right, or obtuse. Compare the square of the length of the longest side with the sum of the squares of the lengths of the two shorter sides. Compare c2 with a2 b2.

How much do I need to invest now, at 5% p.a compound interest, for the total in 6 years to be $10,000
Answer:
$7462 to the nearest dollar.
Step-by-step explanation:
10000 = P(1 + 0.05)^6 where P is the initial investment.
10000 = P * 1.05^6
Taking logs:
log 10000 = log P + 6 log 1.05
log P = log 10000 - 6 log 1.05
log P = 4 - 0.127136 = 3.872864
P = 7462
The table shows the relationship between cups of flour and number of eggs needed in a cake recipe.
Which equation represents the relationship shown?
answers:
y = 2/3x
y = 3/2x
y = 4x
y = 6x
The equation of a line from the given graph is y=2/3 x. Therefore, option A is the correct answer.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
From the given table, the coordinate points are (0, 0) and (6, 4)
Here, slope m=(4-0)/(6-0)
= 2/3
Substitute, m=2/3 and (x, y)=(0, 0) in y=mx+c, we get
0=2/3(0)+c
c=0
Substitute, m=2/3 and c=0 in y=mx+c, we get
y=2/3 x
Therefore, option A is the correct answer.

He is considering switching to a new type of material that will increase his profit, as expressed by the function y = 32x, where x is the number sold and y is the amount of profit. How many more dollars will Jacob earn on each skateboard deck if he switches to the new material? Explain how you found your answer.

Answer:
Inverse functions Inverse Functions If f is a one-to-one function with domain A and range B, we can de ne an inverse function f 1 (with domain B ) by the rule f 1(y) = x if and only if f(x) = y: This is a sound de nition of a function, precisely because each value of y in the domain of f 1 has exactly one x in A associated to it by the rule y = f(x).

As a large truck fills its gas tank, the volume of gas, in gallons, can be modeled with the linear function v = 4.8m + 8.2, where v is the volume of gas and m is the number of minutes it has been filling. Give an interpretation for both the 4.8 and 8.2 parameters in the linear model. Use appropriate units in your explanation.
Step-by-step explanation:
Step one:
given data
we are told that the expression is
v = 4.8m + 8.2
where v is the volume of gas and
m is the number of minutes it has been filling.
Step two:
Required
Asumming the volume is in Liters
the interpretation of the terms in the expression for the volume
4.8 means that for every minute 4.8L of gas enters the gas tank
hence the rate of filling is 4.8L/min
8.2 means that there is 8.2L of gas already in the tank before the filling started.
Gayle is making gift bags and must tie 250 ribbons to them. If Gayle can tie 4 ribbons every 10 minutes, how long will it take Gayle to tie all 250 ribbons?
Answer:
625 minutes
Step-by-step explanation:
Given that:
Time taken to tie 4 ribbons = 10 minutes
Number of ribbons to be tied = 250
To find:
Time taken to tie 250 ribbons.
Solution:
First of all, we need to find the time taken to tie one ribbon.
And then we can multiply it with 250 to find the time taken to tie all the 250 ribbons.
For finding the time to tie one ribbon, we need to divide the time taken to tie 4 ribbons with 4.
Time taken to tie 1 ribbon = [tex]\frac{10}{4} = 2.5[/tex] minutes
Time taken to tie 250 ribbons = 2.5 [tex]\times[/tex] 250 = 625 minutes

Answer:
a, b, c
(all but the last one)
Step-by-step explanation:
a+b+c=180 is true bcuz the sum of interior angles in a triangle is 180
rearrange a+b+c=180 into a+b=180-c
observe that 180-c equals d, so in the equation a+b=180-c replace 180-c with d.
a+b=d so thats true
we already established that d=180-c so thats true as well
and the last one is just not true

Step-by-step explanation:
take y2-y1/x2-x1
6+3/-3=Neg 3
Answer:
C. -3
Step-by-step explanation:
You can do this using two different methods.
First, slope is written rise over run, or y over x. We can find two points and count how much we need to rise and run. The graph already includes the points (2,-3) and (-1, 6), which we will use. If you carefully look at the graph, you can see that if you start from the point (2,-3), you can rise 9 and run -3 to get to the point (-1, 6), which brings me to the next step. As I stated in the beginning, slope is written rise over run. Therefore, the slope is 9/-3, which simplifies to -3, answer choice C.
Another way you can do this is subtracting the y's and subtracting the x's in the same order. The y's go over the x's, and is basically written as a fraction. For this method, we still need two points. We will use the same points as above and listed on the graph, points (2,-3) and (-1, 6). The y's are -3 and 6, and the x's are 2 and -1. Now, subtract.
-3-6 =-9=-3
2-(-1)= 3
As you can tell, both methods of solving for slope worked, and the answer is choice C.
I hope this helps!! Have a great day, and thanks for the points (^人^)

HELLO HUMANS FROM MARS. WILL MARK BRAINLIEST!!!! THIS QUESTION IS ABOUT SNOWFALL. When snow melts after it falls because of the sun, is it considered positive or negative ( - + )?
9514 1404 393
Answer:
positive decrease in depthnegative change in depthStep-by-step explanation:
Depth of snowfall is usually measured above some base. The greater the depth, the higher the surface is above the base.
When the depth decreases, as by melting, the change in depth is negative. That is, the difference between the new depth and the old one is negative. A 12" depth experiencing a change of -1 inch becomes an 11" depth.
If the question is about how much the depth decreased, the decrease is given as a positive value. A 12" depth decreased by (+)1 inch becomes an 11" depth.
The sign of the number of interest depends on what question it is answering.
Natalie bought 4 chicken wings for $7.60. How much does each wing cost? On the double number line below, fill in the given values, then use multiplication or division to find the missing value.
Given :
Natalie bought 4 chicken wings for $7.60.
To Find :
How much does each wing cost.
Solution :
Let, price of each chicken wing is x.
So,
[tex]x = \dfrac{Total price of wings}{Number of wings}\\\\x = \$\dfrac{7.60}{4}\\\\x = \$1.9[/tex]
Therefore, price per chicken wing is $1.9 .
Hence, this is the required solution.
