Answer:
(- 2, 4 )
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 4 = - 3(x + 2) ← is in point- slope form
with (a, b ) = (- 2, 4 )
There were 56 runners to start a race. In the first half of the race, h of them dropped out. In the second half of the race, z of the remaining runners dropped
out. How many runners finished the race?
Answer:
56-h-z runners
Step-by-step explanation:
The only number we're given is 56, so the only thing that we can do is create an expression
Answer:
56 - h - z
Step-by-step explanation:
-h - z is the number of people who dropped out at any time in the race.
56 is the total amount, and you put -h - z behind it.
Therefore, you get 56 - h - z.

Cai left his house for work and was gone 4 2/3 hours. he spent a total of 5/6 hours driving to and from work and didnt go anywhere else. How long was he at work?
A.5 1/2 hours
b. 3 5/6 hours
c. 3 1/6 hours
d. 4 1/6 hours
Answer:
[tex]4\frac{1}{6}[/tex] hours
Step-by-step explanation:
Substract total hours from hours Cai spent driving to find how long he was at work.
[tex]4\frac{2}{3}[/tex] - [tex]\frac{5}{6}[/tex] = ?
Substract the second expression [tex]\frac{2}{3} - \frac{5}{6}[/tex] by the first expression 4.
[tex]\frac{25}{6}[/tex]
Convert to a mixed number.
[tex]4\frac{1}{6}[/tex]
Therefore, the answer is [tex]4\frac{1}{6}[/tex] hours.
The measures of the angles of a triangle are shown in the figure below. Solve for X.
75°
(7X+14)
49°
Answer;
x=6
Step-by-step explanation:
Step-by-step explanation:
Angle in a triangle is 180
75+ (7x+14) +49 =180
75+ 49+ (7x+14)= 180
124+ (7x+ 14) = 180
124+ 14 +7x= 180
138+7x = 180
7x =180- 138
7x=42
x= 6

Answer:
Expand the following expressions.
1. 5 (r +2)
= (5×r) + (5×2)
= 5r + 10
2. 6b (b-2a)
= (6b×b) - (6b×2a)
= 6b²-12ba
3. 8cd (c-2 +40)
= (8cd×c) - (8cd×2) + (8cd×40)
= 8c²d - 16cd + 320cd
= 8c²+ 304cd

SOMEONE PLEASE I NEED HELL AND I WANT TO GO TO SLEEP, but there’s more than one answer btw
Answer:
The second one, third one and the fifth one should be correct. (7 to the 18th power divided 7 to the 9th power, 7 to the 3rd power to the 3rd power, and 7 to the 4th power times 7 to the 5th power)
Step-by-step explanation:
7 to the 8th power times 7 equal 40353607 so if you do all the equations shown you can rule out which ones equal 40353607 and which ones don't. Have a nice sleep!
Answer:
[tex]\frac{7^{18}}{7^{9}}[/tex], (7³)³ and [tex]7^{4}*7^{5}[/tex]
Step-by-step explanation:
[tex]7^{8}*7[/tex] = [tex]7^{9}[/tex] is equivalent to the following exponential expressions:
[tex]\frac{7^{18}}{7^{9}}[/tex], as it applies to the Quotient Rule of Exponents: [tex]\frac{a^{m}}{a^{n}} = a^{m-n}[/tex]. Therefore, you're essentially subtracting the exponents, resulting into [tex]7^{9}[/tex].
(7³)³: The Power-to-Power Rule of Exponents apply in this situation:[tex](a^{m})^{n} = a^{mn}[/tex]. Multiplying the exponent inside the parenthesis by the exponent outside the parenthesis results in an exponent of 9.
[tex]7^{4}*7^{5}[/tex]: the Product Rule of Exponents apply in this situation: [tex]a^{m}*a^{n} = a^{m+n}[/tex]. Adding the exponents of 4 to 5 results in an exponent of 9.

The expression is written with parentheses and the signs will be 5 + 23 + 18 x (8 - 4) = 100.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
5 + 23 + 18 x (8 - 4) = 100
Simplify the expression, then we have
5 + 23 + 18 x (8 - 4) = 100
5 + 23 + 18 x 4 = 100
28 + 72 = 100
100 = 100
The expression is written with parentheses and the signs will be 5 + 23 + 18 x (8 - 4) = 100.
