How to Rewrite 8 + 36 as a product of their GCF and the sum of two factors
Answer:
4 (2 + 9)
Step-by-step explanation:
Given expression:
8 + 36
The greatest common factor is the highest number that divides a number:
8 and 36 ;
Factors of 8 : 1,2,4, 8
36 : 1, 2, 3, 4, 9, 18, 36
The highest common factor is 4;
8 + 36 = 4 (2 + 9)
If f(x) = 3x + 2, then find the value of x such that f(x) = -4. A. -14 B. -10 C. -2 D. 14
Answer:
C.
Step-by-step explanation:
f(x) = 3x+2
f(x) = -4
-4 = 3x+2
-4-2 = 3x
-6 = 3x
-6/3 = x
-2 = x
x = -2

Step-by-step explanation:
Rita goes for a bike ride on a trail by her house. After 15 minutes of riding she sees a mile marker. When she reaches the third mile marker, she realizes that she has been biking for 30 minutes. What is the rate at which she is riding?
Given:
Rita covered 1 mile in 15 minutes.
She covered 3 miles in 30 minutes.
To find:
The rate at which she is riding.
Solution:
Let y be the number of miles covered in x minutes.
Rita covered 1 mile in 15 minutes. So, the point is (15,1).
She covered 3 miles in 30 minutes. So, the point is (30,3).
Slope of the line:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{3-1}{30-15}[/tex]
[tex]m=\dfrac{2}{15}[/tex]
Therefore, she is riding [tex]\dfrac{2}{15}[/tex] miles per minute.

Solve using fraction strips or common denominators:
1/2 + 3/10=
Answer:
4/5 (or 8/10)
Step-by-step explanation:
the least common denominator of 2 and 10 is 10, so you have to multiply the first fraction (1/2) by 5/5 so that the denominator of that fraction will become 10. Since 3/10 already has 10 as the denominator, you leave it. By adding 5/10 and 3/10 together you'll get 8/10.
If the question asks to simplify your answer, divide the numerator and denominator of 8/10 to get 4/5

What slope is perpendicular to:
m = 5/8
The slope that is perpendicular to m = 5/8 is given by; m' = -8/5
When dealing with slope - intercept form of equation of a line, the general equation is;y = mx + c
where;
m is the slope
c is the y-intercept
Now, for a line to be perpendicular to a line above that has it's slope as m, the slope of this new line will be the negative inverse of the first slope. This is; m' = -1/mApplying that to our question, it means the slope that is perpendicular to m = 5/8 is; m' = -1/(5/8) = -8/5Read more at; https://brainly.com/question/21441448
Simplify negative 3 over 4 divided by 2 over negative 8 . (1 point)
A.−6
B. −3
C. 3
D. 6
Answer:
Option B
Step-by-step explanation:
In order to find the answer to this question you need to use KCF and solve. Remember that negative times a positive equals a negative.
[tex]-\frac{3}{4} \div\frac{2}{8}[/tex]
Use KCF
[tex]-\frac{3}{4} \times\frac{8}{2}[/tex]
Multiply:
[tex]3 \times 8 =24[/tex]
[tex]4\times2=8[/tex]
Remember that negative times a positive equals a negative:
[tex]-\frac{24}{8}[/tex]
Simplify:
[tex]24\div8=3[/tex]
[tex]8\div8=1[/tex]
[tex]-\frac{3}{1} =-3[/tex]
[tex]=-3[/tex]
