Eliza and her mother have a combined age of 51 years. If her mother is 39 years old , how old is Eliza?

Answer:

Step-by-step explanation:

Yes it's a function.

You may be looking at v which produces m

You may be looking at r which also produces m.

That's fine. Two different x values (the domain) can produce the same y value. Lots of functions do that. (you'll study parabolas pretty soon and all that open up or down have two x values producing the same y value).

If you have a member of the domain producing 2 y values,  that doesn't work. That would not be a function.

This example is a function.

Answer:

x > 5

Step-by-step explanation:

Answer:

we have -3x < -15,

so

3x > 15,

x > 5

Answer:

3/16

Step-by-step explanation:

If an article takes half of the page then;

1article = 1/2 of a page

3/8 of the article = x

Cross multiply

1×x = 1/2×3/8

x = 3/(2×8)

X = 3/16

Hence the photo takes 3/16 of the magazine

Answer:

No. Her claim is too large. The actual value is 4 cm.

Because Volume = l³

4³ equals to 64 which means size of the edge is 4cm.

Answer:

y = -2x

Step-by-step explanation:

Equation in slope-intercept form is y = mx + b.

m = slope = ∆y/∆x

Using any two points on the line, say (0, 0) and (-20, 40),

Slope (m) = (40 - 0) / (-20 - 0) = 40/-20

Slope (m) = -2

b = y-intercept = the value of y when x = 0.

b = 0

To write the equation of the line, substitute m = -2 and b = 0 into y = mx + b

Thus:

y = -2x + 0

y = -2x

3= 9

4=12

5=15

Step-by-step explanation:

Formula is 3x

2 x 3= 6

3 x 3=9

4 x 3= 12

15/3= 5

The coefficient is the number next to the letter.

Although the x squared term has a coefficient of 1, it is not listed in the answer choices. However, the coefficient of the middle term 6x is listed.

Answer:

median- 58.5

first quartile- 56

third quartile- 65

interquartile range- 9

Step-by-step explanation:

median is when you put the numbers from least to greated and find the middle number; so, you will put this set in that order= 38, 46, 55,56,58,59,61,65,67,75. now, you get stuck between 58 and 59. so you add them and divide by two to get 58.5. thats the median. The first quartile is any number from the set that is smaller than the median, basically the first half of it. now you will just find the median of that which is 56. that is your first quartile. third quartile is the second half of the set, any number in the set that is greater than the median. you will find the median of that half to get 65. that is your 3rd quartile. interquartile range ius the difference bewteen your first and third quartile. 65-56 is 9. hope this helped marck as brainlyest and help me with my que tooo :)

Answer: f = 100

Step 1.

We'll need to expand 3(f - 91) by multiplying a term and an expression. The following product distributive property will be used: A(B + C) = AB + AC.

In the example, the expression will consist of 2 terms.

First term: 3 and f.

Second term: 3 and -91

Rewrite 3(f - 91) like this.

3f - 3 × 91

Step 2.

Multiply 3 by 91.

3 × 91 = 273

Hence, the answer is 100.

Answer:

23.7°

Step-by-step explanation:

To obtain the value of AB ; Use the cosine rule ;

Recall:

c² = a² + b² - 2ab Cos C

c² = 24² + 11² - 2*24*11 Cos75

c² = 576 + 121 - 528 * 0.2588190

c² = 697 - 136.656432

c² = 560.343568

c = sqrt(560.343568)

c = 23.6715

Hence, c = AB = 23.7°

Answer:

40ft

Step-by-step explanation:

Add up all four sides of your rectangle:

15ft + 15ft +5ft + 5ft = 40ft

You can find the other 5ft (the side that is missing) if you notice that the smaller sections are squares.
