Answer: (-3,-4)
Step-by-step explanation:
4x-y=-8
y=2x+2
4x-(2x+2)=-8
2x-2=-8
y=2x+2
x=-3
y=2(-3)+2
y=-4
x=-3 , y=-4
On a map, there are 3 centimeters between two cities. The actual distance between the cities is 45 kilometers.
What was the scale used for the map?
please help
Answer:
15km/cm
Step-by-step explanation:
All you do is divide 45 by three to determine your scale
Answer:
3cm on map = 45 km
1 cm on map = Xkm
Xkm = 45 / 3
Xkm = 15km
Therefore scale = 1:15000

The angle of elevation from a person standing on the ground to a balloon in the air is 20°. The person walks 10 feet forward and the angle of elevation to the balloon is now 30°. How far away is the person from the balloon (after they walked ten feet)?
Answer:
they are 30 ft away from the balloon
Step-by-step explanation:
every foot they move back equals one degree higher in the angle ten feet would equal 10 degrees.
Find the slope of the line that passes through the points, A(0,2) and B(4, -1).
Answer:
Slope=M=y2-y1/X2-X1=
-1 -2 /4-0=
-3/4 =
-0.75
Step-by-step explanation:
Hope this helped!!!!
Answer:
y=(-3/4)+2
Step-by-step explanation:
Hello there! In order to solve this problem we will have to find the slope of the line and then use the point slope formula
Firstly, lets solve for the slope by finding the change in y over the change in x:
slope (m)= [tex]\frac{y2-y1}{x2-x1}[/tex]
We will plug in the values of the points given and find that:
slope (m)= [tex]\frac{-1-2}{4-0}[/tex]
this equals (-3/4)
from here we will use the point slope formula to find for the equation that the line passes through. You can use either point for this step, I will be using A(0,2).
Point-slope equation:
[tex]y-y1=m(x-x1)[/tex]
Plugging in values:
[tex]y-2=(\frac{-3}{4})(x-0)[/tex]
after isolating y we find that the equation is:
[tex]y=\frac{-3}{4} x+2[/tex]
Hope this helps!

Subtract: 3.8 - 2.923. Explain in your own words how you would solve this, in detail, from start to finish.
Given:
3.8 - 2.923
To find:
The subtraction.
Solution:
We have,
3.8 - 2.923
It can be written as
3.800 - 2.923
After subtraction, we get
3 . 8 0 0
-2 . 9 2 3
------------------
0 . 8 7 7
-----------------
So, 3.800 - 2.923 = 0.877.
Therefore, the value of 3.800 - 2.923 is 0.877.
Allison decided to start by saving $10 the first week of the year in her bank. Then, the next week she would save $2 more dollars than the previous week and put that in the bank (e.g. on week 2 she saved $12). If she kept increasing the amount in this way how much will she have saved in total by the end of the year? Question 4 options: $112 $114 $3172 $3340

Mr.Davis treated his team to a pizza party after their last baseball game. He bought 7 cheese pizzas and spent less than $70.00. Write and solve an inequality to find the cost of each pizza.
Answer:
About $10 for each Pizza.
Step-by-Step:
We can use the equation 7a=70 to solve the problem. a= Amount. We divide 7 on both side which is 10. So a=10.

Answer:
Angle 8 = 83
Angle 5 = 180 -83 = 97
Step-by-step explanation:
Check: Just an example to check using Co- interior angles
Angle 2 + Angle 5 = 180 degrees
83 +97 = 180 degrees
180 degrees = 180 degrees
Therefore Angle 5 = 97 degrees and Angle 8 = 83 degrees
X > -9 written in words
Answer:
X is greater than negative-nine (-9).
can someone please help?
Answer:
x=86
Step-by-step explanation:
we know that all the angles in a triangle add up to 180 degrees.
if you add 74+20, you get 94. then, subtract 94 from 180 to get 86! sorry if this is wrong i tried my best T^T
-4x –12 = 48 a.x = 9 b.x = -9 c.x = 15 d.x = -15
Answer:
d) x= -15
Step-by-step explanation:
-4x-12=48
1. Add 12 to both sides
-4x-12+12=48+12
2. -4x=60
3. Divide -4 from both sides
Final Answer: x= -15
Two two-digit numbers, 'AB' and 'BA', sum to
produce a three-digit number in which the second digit
is equal to A. The addition is represented below. (Note
that the variables are used to represent individual digits;
no multiplication is taking place).
AB + BA= 1A2
What is B?
9514 1404 393
Answer:
9
Step-by-step explanation:
The value of the sum is ...
(10A +B) +(10B +A) = 102 +10A
11A +11B = 102 +10A
A +11B = 102 . . . . . . . subtract 10A
Dividing by 11, we have ...
A/11 +B = 9 3/11
This tells us A=3, B=9.

Check
39 + 93 = 132
Answer:
To make this division work, you multiply the numerator by the reciprocal of the ... Therefore, ((x - 4) / (1 / 2)) / (1 / (x + 4)) = ((x - 4) * 2) * (x + 4) / 1. ... below. (Note that the variables are used to represent individual digits; no ... In the ten's column, we can see that a one must carry in order to get a digit in the hundred's place.

Solve the following:
4x-3=2x+7
Answer:
= 5
Step-by-step explanation:
Add 3 to both sides of the equation 4 − 3 = 2 + 7 4x-3=2x+7 4x−3=2x+7 4 − 3 + 3 = 2 + 7 + 3
Simplify Add the numbers Add the numbers 4 = 2 + 1 0
Subtract 2 2x 2x from both sides of the equation 4 = 2 + 1 0 4x=2x+10 4x=2x+10 4 − 2 = 2 + 1 0 − 2
Simplify Combine like terms Combine like terms 2 = 1 0
Divide both sides of the equation by the same term 2 = 1 0 2x=10 2x=10 2 2 = 1 0
Simplify Cancel terms that are in both the numerator and denominator Divide the numbers = 5
Solution x=5
