Answer:
f(x) will be any function that has the slope of 3/4
slope is represented by m in y = mx+b.

Answer:
C) 10.101
Step-by-step explanation:
A terminating decimal is one that is not repeating and ends at some point.
The line over the 3 in A means that it's a repeating decimal.
[tex]\sqrt{10}[/tex] is an irrational number, so it never ends.
The line over the 6 in D means that it's a repeating decimal.
C is the right answer because 10.101 has a definite endpoint :)

subract 5 5/21 from 13 1/7
Answer:
The answer is 166/21, or 7 19/21
Step-by-step explanation:
First, you would set up the equation, which is:
13 1/7 - 5 5/21
Next, you would turn them into an improper fraction, which is:
92/7 - 110/21
Then, you would multiply 92/7 by 3/3 because that is the least common multiple for 21 and 7 (which are the denominators). When you are done multiplying, the equation would be:
276/21 - 110/21
Afterwards, you would subtract the numerators and leave the denominators alone, which gives you the answer 166/21. As a mixed number, this would equal 7 19/21.
Answer:
7 19/21
Step-by-step explanation:
13 1/7 - 5 5/21
Get a common denominator
13 1/7*3/3 - 5 5/21
13 3/21 - 5 5/21
We need to borrow 1 from the 13 in the form of 21/21
12 +21/21 + 3/21 - 5 5/21
12 24/21 - 5 5/21
7 19/21

The line of reflection is perpendicular to the line segments connecting corresponding vertices.
The line segments connecting corresponding vertices are all congruent to each other.
The line segments connecting corresponding vertices are all parallel to each other.

Katherine has two types of iodine in her lab. She has brand 232 iodine, which costs thirty-six cents
per ounce. She also has brand 880 iodine, which costs $2.04 an ounce. How many ounces of each should she use if she wants to make three hundred ninety-three ounces of iodine that cost a total of $255.72?
Answer:
Number of ounces of iodine 888 brand = 68
Number of ounces of iodine 232 brand = 325
Step-by-step explanation:
Given the following ;
Brand 232:
Cost per ounce = 36cent
Brand 880:
Cost per ounce = $2.04 = 204cent
Assume the following :
Number of ounces of 232 brand = x
Number of ounces of 888 brand = y
Total ounces to be made :
x + y = 393 - - - (1)
Total cost of iodine :
Brand 232 = 36x
Brand 888 = 204y
36x + 204y = 25572 - - - - (2)
From (1)
x = 393 - y - - - - (3)
Substitute (3) into (2)
36(393 - y) + 204y = 25572
14148 - 36y + 204y = 25572
-36y + 204y = 25572 - 14148
168y = 11424
y = 11424 / 168
y = 68
From ; x = 393 - y
y = 68
x = 393 - 68
x = 325
Number of ounces of iodine 888 brand = 68
Number of ounces of iodine 232 brand = 325
HELLO THERE. PLS HELP WITH GEOMETRY
Answer:
x = 114°
y = 27
Step-by-step explanation:
To get x, we simply subtract 66° from 180°. Because of same-side interior angles, the angle below x is 66°.
To find y, we set the expression equal to 66° because they are the same angle. When we solve for y, we get 27.
Answer:
x= 114,
y= 27
Step-by-step explanation:
x= 180 - 66 = 114
6y - 96 = 66, 6y= 66+96, 6y= 162, y= 162/6, y= 27

The measure of a tangent-tangent angle is half the difference of the
measures of the intercepted arcs.
A. True
B. False
Answer:
True
Step-by-step explanation:
The measure of the angle where secants intersect outside the circle is half the difference of the measures of the intercepted arcs. A pair of tangents is a special case where the intercepted arcs meet each other. The same relation regarding arc and angle measures still applies.
The given statement is true.
The measure of a tangent-tangent angle is one - half the difference of the measures of the intercepted arcs.
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Now, The diagram is attached below
AB and BC are the two tangents
By exterior angle theorem
∠3 = ∠2 + ∠4
So ∠2 = ∠3 - ∠4
Now we find angle 3 and 4, we know when a chord and tangent intersect at a point then the measure of angle is one half of measure of intercepted arc
∠3 = 1/2 arc ADC
∠4 = 1/2 arc AC
∠2 = ∠3 - ∠4
∠2 = 1/2 arc ADC - 1/2 arc AC
∠2 = 1/2 ( arc ADC - arc AC)
Thus, The measure of a tangent-tangent angle is one half the difference of the measures of the intercepted arcs.

Annie is 3 years older than James. (Use J represent James’ age.)
a. Write an expression to represent Annie's Age.
b. If the sum of their ages is 18, write an equation to represent this situation
C. How old is Annie ?
Answer:
Step-by-step explanation:
James' age = J
a) Annie is 3 years older than James so,
Annies age = 3 +J
b) Sum of their ages is 18 so,
Annies age + James' age = 18
= 3 + J + J = 18
2J = 18-3
J = 15/2 = 7.5
c) Annies age = 3 + J = 3 + 7.5

Find the equation of the line that passes through the two points (5,-3) and (-5,2). Write your answer in standard form. Help me I don’t know how to write this
Answer:
x + 2y = -1
Step-by-step explanation:
First, we'll find the slope.
Slope = (2 - (-3)) / (-5 - 5) = 5 / -10 = -1/2
Since we know the slope and a point that belongs to the line, we can write this in point-slope form which will be:
y - 2 = -1/2(x - (-5)) *I used (-5, 2) but it doesn't matter which point you use
y = -1/2(x + 5) + 2
y = -1/2x - 1/2
Standard form:
1/2x + y = -1/2
x + 2y = -1

Answer:
2/3, 1, and 6/5
Step-by-step explanation:
This is all just a matter of substitution. The values given of x = 1, x = 4/9 and x = 1 1/3 just need to be substituted in as x itself.
If x = 1, then the expression will be as the following: 4/15÷1+0.4. Dividing anything by 1 is just the same number, so 4/15 remains the same. 0.4 as a fraction is 4/10. A common denominator is 30, as both 10 and 15 fit into 30, so:
8/30+12/30=20/30, which can be simplified into 2/3
If x = 4/9, then we just substitute again. 4/15÷4/9+0.4. Due to BIDMAS, we do 4/15÷4/9 first, and to divide fractions, we use the KCF rule of Keep, Flip, and Change. We Keep the first fraction (4/15), Change the division sign into multiplication and then Flip the second fraction so it becomes 9/4
Now, we multiply the two fractions (4/15×9/4) to get 3/5, and then adding 4/10 to that gives us just 1.
If x = 1 1/3, we do the exact same thing we did for x = 4/9 to get 6/5. Good luck.

Answer:
the solution is (-2, 1)
Step-by-step explanation:
In the first equation, substitute -2 for x. We get:
y = -2 + 3 = 1
So the solution is (-2, 1)
The solution of system of Equations is x= -2 and y= 1.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have the Equation:
y= x+ 3
x= -2.
So, putting the values in equation in (1) we get
y = -2 + 3
y = 1.
Thus, the solution is x= -2 and y= 1.
