4 times the sum of 8 and a number is 32. What is that number?
Step-by-step explanation:
let the unknown be x
4(8 + x) = 32
32 + 4x = 32
4x = 32 - 32
4x = 0
x = 0 ÷ 4
x = 0
if you wanna check,
4(8 + 0)= 32
32 + 0 = 32
32 = 32
hope I got it right&^^,good luck!

Answer:
-5n + 16
Step-by-step explanation:
Distribute the 7 to the equation inside the parenthesis.
7(n + 1) - 12n + 9
7n + 7 - 12n + 9
Bring the -12n towards the 7n.
7n - 12n + 7 + 9
Add or subtract like terms.
7n - 12n + 7 + 9
-5n + 16
Answer:
-5n + 16
Choose the correct math expression for: 45 more than the difference of 35 and 13.
(35 - 13) - 45
(35 - 13) + 45
(35 + 13) + 45
Answer:
(35-13)+45
Step-by-step explanation:
The second expression because as the difference of 35 and 13 is 35-13, it cannot be the third one. As the first phrase says 45 MORE than the 35-13, we need to have +45 after, and the second equation has +45, so the second expression is true about the statement. Hope it helps!

Angle 1 = 120
Step-by-step explanation:
(4x + 40) = (2x + 80)
4x + 40 = 2x + 80
2x + 40 = 80
2x = 40
x = 20
2(20) + 80
40 + 80
120
Angle 1 is a vertical angle from (2x + 80) so they have the same measurement.

What is the y-intercept of the function f(x)=4 - 5x?
-5
-4
4
5
Answer:
The y-intercept is 4. The third option is correct
Explanation:
The equation of a line is written as:
y=mx+b
Where m is the slope and m is the y-intercept or the point where y crosses the x-axis.
The given function is f(x)=4-5x.
It can be rewritten as
f(x)=-5x+4.
We can recognize the slope m=-5 and the y-intercept b=4
First option: Incorrect. The y-intercept is not -5
Second option: Incorrect. The y-intercept is not -4
Third option: Correct. The y-intercept is 4
Fourth option: Incorrect. The y-intercept is not 5
The y-intercept of the equation f(x) = -5x + 4 is 4.
How to find the y-intercept from slope intercept equation?The y-intercept is the value of y when x = 0.
The slope intercept equation can be express as follow:
y = mx + bwhere
m = slope
b = y-intercept
Therefore, let's model the equation f(x) = 4 - 5x to the slope intercept form.
f(x) = -5x + 4
Therefore, according to the slope-intercept equation, the slope is -5 and the y-intercept is 4.
The y-intercept is the value of y when x = 0.

Write the equation of a line that is perpendicular to y = -8 3 x + 4 and goes through the point (5, 2)
Answer:
y = 3/8x + 1/8
Step-by-step explanation:
The slope of a perpendicular line is the opposite and reciprocal of the original slope.
-8/3 -> 3/8
Find the new y-intercept.
y = 3/8x + b
2 = 3/8(5) + b
2 = 1.875 + b
0.125 = b
y = 3/8x + 1/8

Tom performs a dilation of ⅓ on a triangle. He then classifies the image and pre-image as being congruent. Is Tom correct? Why or why not?
Answer: Tom is incorrect.
Step-by-step explanation: Congruent is defined as having exactly the same angle measurements and exactly the same side lengths.
In the 1/3 dilation, the angles will remain the same, but all the sides will be shorter, 1/3 the lengths of the original image. The image and pre-image are not congruent. They are similar.

Chandler is on a hike in the woods. He has an altimeter with him, and Chandler uses it to measure his height above sea level at various points in his hike. He starts out at 120.4 meters above sea level, then hikes up an additional 850.0 meters to the crest of a hill. Chandler takes a break, then hikes down into a valley that is 430.7 meters below the crest. How far above sea level, in meters, is Chandler when he is in the valley?
Answer:
539.7 meters above sea level.
Step-by-step explanation:
Okay in order to solve this problem we can take it one step at a time. First, he starts at an altitude of 120.4 meters above sea level.
Then he hikes up an additional (meaning we add) 850.0 meters.
120.4 + 850.0 = 970.4
Next, Chandler hikes down (meaning we subtract) 430.7 meters.
970.4 - 430.7 = 539.7
Therefore, we can see that when Chandler is in the valley he is at an altitude of 539.7 meters above sea level.
Answer:
539.7 meters above sea level.
Step-by-step explanation:
, he starts at an altitude of 120.4 meters above sea level.
he hikes up an additional ( add) 850.0 meters.
120.4 + 850.0 = 970.4
Chandler hikes down ( subtract) 430.7 meters.
970.4 - 430.7 = 539.7
we can see that when Chandler is in the valley he is at an altitude of 539.7 meters above sea level.
