Step-by-step explanation:
Isabella and her cousin rodrigo have the same birthday, but isabella is 15 years older than rodrigo is x years old. which table of value shows this relationship
Solution:
Let x represent Rodrigo's age and let y represent Isabella's age. Since Isabella is 15 years older than Rodrigo, hence her age is given by the equation:
y = x + 15
You can use a table to represent the relationship between their ages. Let us find the corresponding Isabella age for the following Rodrigo age.
Rodrigo: 10 20 30
Isabella: 25 35 45
When x = 10: y = x + 15 = 10 + 15 = 25
When x = 20: y = x + 15 = 20 + 15 = 35
When x = 30: y = x + 15 = 30 + 15 = 45

Question: The measures of the exterior angles of a polygon are x°, 2x°, 120°, 3x°, 18°, and 120°. What is the value of x?
A. 120
B. 360
C. 77
D. 17
9514 1404 393
Answer:
D. 17
Step-by-step explanation:
The sum of the exterior angles of a polygon is 360°.
x° +2x° +120° +3x° +18° +120° = 360°
6x +258 = 360 . . . . . . . collect terms, divide by °
6x = 102 . . . . . . . . . subtract 258
x = 17 . . . . . . . . divide by 6
Assume that x = x(t) and y = y(t). Let y = x^2 + 6 and
dx/dt=4 when x=1
Find dy/dt when x = 1
Answer:
[tex]\frac{dy}{dt}[/tex] = 8
Step-by-step explanation:
Given:
x = x(t) and y = y(t)
Let y = x² + 6
By differentiating the given equation with respect to t,
[tex]\frac{dy}{dt}=\frac{d}{dt}(x^{2}+6)[/tex]
[tex]\frac{dy}{dt}=\frac{d}{dt}(x^{2})+\frac{d}{dt}(6)[/tex]
Since, [tex]\frac{dx}{dt}=4[/tex] when x = 1
[tex]\frac{dy}{dt}=2x\frac{dx}{dt}+\frac{d}{dt}(6)[/tex]
[tex]\frac{dy}{dt}=2(1)(4)+0[/tex] [By substituting the values of [tex]\frac{dx}{dt}[/tex] and x = 1]
[tex]\frac{dy}{dt}[/tex] = 8

I want to know if anyone can help with a math textbook. It is page 302, evens only. Skip word problems. Show work if you can, if you can't, then it's alright.
Step-by-step explanation:
Hopefully I'm right,but what you do is add the ones with variables together so
Question 15
3a + 2 + 3a + 7so 3a+3a= 6a and 7+2=9
so you have to add the ones that are similar but never add
3a+7 because they are not the same37. 5x-2y

93 is the sum of a number g and 58.
Answer:
G is 35.
Step-by-step explanation:
You can make the equation 93 = g + 58. In order to find the variable g, you have to isolate it. So you can subtract 93 by 58 and you get 35. To double check your work, just plug in your answer in g.
93 = 35 + 58
93 = 93 ✔️
The answer is 35.

A store marks up a laptop 150% from its original price of $299. There is a sale for 25% off all items in the store. What is the sale price for the computer?
Answer:
B. 336. 38
Step-by-step explanation:
So, what you want to do is multiply the original price ($299) by the first markup percentage (150%)
299*1.50= $448.50
that is your markup price!
then you have to do the sale % (25%)
so you'll multiply your (25%) by your new price ($448.50)
448.50*.25= $112. 125
THIS IS NOT YOUR ANSWER!
don't forget that!
you will then subtract the sale price ($112.125) by the upcharged price ($448.50)
448.50-112.125= 336. 375
Round up then there is your answer!
= $336. 38

A line passes through the points (-4, -16) and (0, 12). What is its equation in slope-intercept
form?
Answer:
[tex] \large \boxed{y = 7x + 12}[/tex]
Step-by-step explanation:
Goal
Write the equation of a line in slope-intercept form.Given
Coordinate points which are (0,12) and (-4,-16).Step 1
Find the slope by using slope formula or rise over run which is the changes of y over the changes of x[tex] \large{m = \frac{y_2-y_1}{x_2-x_1}}[/tex]
Substitute the coordinate points in the formula.
[tex]m = \frac{12 - ( - 16)}{0 - ( - 4)} \\ m = \frac{12 + 16}{0 + 4} \\ m = \frac{28}{4} \longrightarrow \frac{7}{1} \\ m = 7[/tex]
Step 2
Rewrite the equation by substituting the slope in slope-intercept form.[tex] \large{y = mx + b}[/tex]
Substitute m = 7.
[tex]y = 7x + b[/tex]
Step 3
Substitute any given coordinate points in the rewritten equation.Substituting any given coordinate points will give the same solution.
Step 3.1
Substitute (0,12) in the equation.[tex]y = 7x + b \\ 12 = 7(0) + b \\ 12 = 0 + b \\ 12 = b[/tex]
Step 3.2
Substitute (-4,-16) in the equation.[tex]y = 7x + b \\ - 16 = 7( - 4) + b \\ - 16 = - 28 + b \\ - 16 + 28 = b \\ 12 = b[/tex]
Step 4
Rewrite the equation again by substituting the value of b.[tex]y = 7x + b[/tex]
Substitute b = 12.
[tex]y = 7x + 12[/tex]
Hence, the solution is y = 7x+12.

Please help!! I will make you brainlest.
Answer:
Step-by-step explanation:
These problems are based on triangle ratios. You cannot use the Pythagorean theorem to solve them.
The first triangle is a 45 45 90 degree triangle (I'm talking about the angles), and so, the ratio is 1:1:[tex]\sqrt{2\\}[/tex], so I have to divide the hypotenuse by [tex]\sqrt{2\\}[/tex] to get the legs. The hypotenuse is 15[tex]\sqrt{6}[/tex], so that divided by [tex]\sqrt{2\\}[/tex] is 15[tex]\sqrt{3\\}[/tex]. X is the same length as y because of the triangle ratio, so both x and y for the first triangle are 15[tex]\sqrt{3\\}[/tex].
The second triangle is a 30 60 90 degree triangle, so the ratio is x:x[tex]\sqrt{3}[/tex]:2x. The short leg is 7[tex]\sqrt{3}[/tex], so 7[tex]\sqrt{3}[/tex] * 2 is the hypotenuse, which is 14[tex]\sqrt{3}[/tex]. The long leg is 7[tex]\sqrt{3}[/tex] * [tex]\sqrt{3}[/tex], which is 21. So, x for the second triangle is 14[tex]\sqrt{3}[/tex], and y for the second triangle is 21.
Answer:
Question 9: x = [tex]15\sqrt{3}[/tex], Question 10: y = [tex]15\sqrt{3}[/tex], Question 11: x = [tex]14\sqrt{3}[/tex], Question 12: y = 21
Step-by-step explanation:
Question 9-10: Right triangles with 45°, 45°, 90° have a special rule, the legs of the triangle are equal, so x = y. Now you can form the statement [tex]2x^2 = 1350[/tex], and because x = [tex]15\sqrt{3}[/tex], so does y.
Question 11-12: Right triangles with 30°, 60°, 90° also have a special rule, the side corresponding to 30° is half the length of the hypotenuse and the side corresponding to 60° is [tex]\sqrt{3}[/tex] times as great as the 60°. x is 2 times as big as [tex]7\sqrt{3}[/tex], so its length is [tex]14\sqrt{3}[/tex]. Y is [tex]\sqrt{3}[/tex] as great as [tex]7\sqrt{3}[/tex], so its length is 21.

16. Hanna has a bag of 23 marbles. 5 marbles are red, 6 marbles are blue, and the rest
are pink. Abby takes out two pink marbles without replacing them. What is the
probability that the next marble he draws will be blue?
A. 10/21
B. 4/21
C. 2/7
D. 6/23
Answer:
C. 2/7
Step-by-step explanation:
When two pink marbles are taken without replacement then the total number of marbles in the bag are reduced to 21 marbles. So the blue marble, which are currently in total 6 marbles, is taken out of the total of 21 marbles. The calculation of which is done as below:
Probability of Next Marble to be blue
= Blue Marble / Total Marbles in the bag
= 6 / 21
= 2 / 7
Hence, the correct option is C. 2/7

angle 9 and angle 10 are corresponding and complementary angles formed by two parallel lines cut by a transversal. find m angle 9
Answer:
45 degrees
Step-by-step explanation:
if <9 and <10 are corresponding, it means they are equal i.e <9 = <10
Since <9 and <10 are also complementary angles, their sum will be 90 degrees
<9+<10 = 90
<9 + <9 = 90
2m<9 = 90
m<2 = 90/2
m<2 = 45 degrees
Hence the measure of angle 9 is 45 degrees
Slope is –2, and (5, 3) is on the line.
To be put into slope intercept form
i wish that i could help you but I just dont understand it... I am sorry
Answer: putting that in slope intercept form : y=-2x+10
Step-by-step explanation:
slope intercept form is y=mx+b.
m= the slope
the slope you gave us is -2
b= the y intercept
a y intercept is the coordinate that touches/crosses the y axis.
to find the y intercept, use the slope (rise over run) you will eventually cross the y axis at 10.
y=-2x+10
i think.
