Answer:
a negative plus positive equals a negative-
Answer:
"To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values. The result takes the sign of the integer with the larger absolute value. The sum of any integer and its opposite is equal to zero."
Step-by-step explanation:
Simpler Explanation: If you add a positive number with a negative number, the sign (negative/positive) of the sum is the same as the integer (number) with the largest absolute value. For example;
1. 10 + -12 = -2
Here, the sum has the same sign (negative) as the largest number in the equation (-12).
2. 7 + -3 = 4
Here, the sum has the sign (positive) as the largest number in the equation (7).

If f (x) = x^2 + 3, evaluate f (-4).
=
A) -5
B) 19
C
11
D) -13
Answer: B) 19
Step-by-step explanation:
To solve this problem, simply plug in -4 for x:
[tex]f(x)=x^{2} +3\\f(x)=(-4)^{2} +3\\f(x)=16+3\\f(x)=19[/tex]
Hope it helps :) and let me know if you want me to elaborate/explain further
Answer:
D. -13
Step-by-step explanation:
If you substitute -4 in for x you get -4^2+3, so when you simplify you get -16+3 which equals -13.
f(x)=x^2+3
f(-4)= -4^2+3
f(-4)= -16+3
f(-4)= -13
a boat traveled 14 miles per hour downstream. the trip upstream was at a speed of 10 miles per hour. what is the speed of the boat in still water? what is the speed of the current
Answer:
(im not sure what the first question is asking me)
Speed of the current is 2 miles per hour
Step-by-step explanation:
The reason the current is 2 miles per hour is because it when going down stream they were going 14 miles per hour, going upstream they went 10. The difference is 4mph. So if the current pushes you 2mph when going down stream and holds you 2 mph when going up, the constant speed is 12mph then you add and subtract 2 becuase of the two directions youre traveling. hence 10mph and 14mph.

Rewrite each equation in standard form.
3. y-2=-(x+7)
Answer:
y-2=-x-7
Step-by-step explanation:
i think this helps
Answer:
x + y = - 5Step-by-step explanation:
The standard form of linear equation:
ax + by = cConvert the given from point- slope to standard form:
y - 2 = - (x + 7)y - 2 = - x - 7x + y = - 7 + 2x + y = - 5[12(x+3)-4]-2(x-1)+6]
10(x + 4)
Step-by-step explanation:
Simplify :
[12(x + 3) - 4] - 2(x - 1) + 6
= [12x + 36 - 4] - 2x + 2 + 6
= 12x - 2x + 36 - 4 + 2 + 6
= 10x + 32 + 8
= 10x + 40
= 10(x + 4)
Demetria went to her local zoo that featured 4 bear exhibits. If the zoo features 16 exhibits in total, then what percent of the zoos exhibits features bears? Round your answer to the nearest tenth if necessary.
Given-
Number of exhibits = 4

Write an equation of the line that passes through the point (4, –5) with slope 2.
A. y−4=−2(x+5)
B. y+5=2(x−4)
C. y−4=2(x+5)
D. y+5=−2(x−4)
Answer:
The correct choice is option B. y + 5 = 2(x−4)
Step-by-step explanation:
slope = 2
y = mx + b
-5 = 2(4) + b
-5 = 8 + b
-8 -8
------------------
-13 = b
y = 2x - 13, in other words --> y + 5 = 2(x−4)
So, y + 5 = 2(x − 4) is the equation of the line that passes through (4, -5).
