Answer:
Step-by-step explanation:
1) 5 - [-5] = 5 + 5 = 10
2)8 - 13 = 8 + (-13) = -5
3) 12 +(-3) = 9
4) x + (-7) = 5
x - 7 = 5
x = 5 + 7
x = 12
We need to add 12 to (-7) to get 5
5) 7 - x = -5
7 = -5 +x
7 + 5 = x
12 = x
We need to take away 12 to 7 to get (-5)
6) 7 - (-10) = 7 + 10 = 17

how can we make a denominator as a unit rate like 1
Answer:
Step-by-step explanation:
When you have a rate, eg. The price is for every number of items, and the quantity in the denominator is not 1, you can calculate the price or the unit rate per unit by completing the division: the numerator divided by the denominator.

Convert from the given standard form of a linear equation to the slope intercept form of a linear equation
1. x+ 5y = 5
2. 3x + 2 y = 4
3. 2x+ y = 4
4. 4x - 2y = 6
5. 8.x- 4y = 16
6. 3x+ 4y = 4
7. 9x - 4y = -16
8. 2x-5y = 10
9. 3x +5y = 10
10. 7x - y =4
(•‿•)
Step-by-step explanation:
remember, we need to get to an expression of the form
y = ax + b
1.
x + 5y = 5
5y = -x + 5
y = (-1/5)x + 1
2.
3x + 2y = 4
2y = -3x + 4
y = (-3/2)x + 2
3.
2x + y = 4
y = -2x + 4
4.
4x - 2y = 6
2y = 4x - 6
y = 2x - 3
5.
8x - 4y = 16
4y = 8x - 16
y = 2x - 4
6.
3x + 4y = 4
4y = -3x + 4
y = (-3/4)x + 1
7.
9x - 4y = -16
4y = 9x + 16
y = (9/4)x + 4
8.
2x - 5y = 10
5y = 2x - 10
y = (2/5)x - 2
9.
3x + 5y = 10
5y = -3x + 10
y = (-3/5)x + 2
10.
7x - y = 4
y = 7x - 4
find the equation of the line shown
Answer:
y=x+1
Step-by-step explanation:
find 2 points which they are on the line
for example:
f(0)=1 Basically shows: x=0,y=1
f(1)=2 Also: x=1,y=2
Find the slope of the line
m=∆y/∆x
[tex]m = \frac{2 - 1}{1 - 0} = 1[/tex]
Also we know:
y-y0=m(x-x0)
Put one of the points instead of y0 & x0:
y-1=1(x-0)
y=x+1
(An easy way is: put 2 points of the line in this equation y=ax+b and find a and b)

Which expression is a quadratic binomial?
A.) x^2 - 16x
B.) 12x^4 + 3x^2 - 6x - 1
C.) 9x^2
D.) 6x^4 - 12x
Answer:
A
Step-by-step explanation:
A quadratic is 'involving the second and no higher power of an unknown quantity or variable.'
Therefore, we can exclude b and d easily because both have a higher power of 2. 9x^(2) is not a binomial because it only has 1 term (i think its called a term) leaving A, x^2-16x as the only answer left.

Frank can purchase bags of apples in four sizes. Which size is the best buy? *

2-lb bag for $3.33
3-lb bag for $4.70
4-lb bag for $5.14
5-lb bag for $6.20
Other:
The size of the bag to buy is 5-lb bag for $6.20
What is the unit rate?A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.
Given that, Frank can purchase bags of apples in four sizes.
To find the best size, checking for the price of bags per pound,
1) 2-lb bag for $3.33
so, for 1 pound = 3.33/2 = $1.665
2) 3-lb bag for $4.70
so, for 1 pound = $1.56
3) 4-lb bag for $5.14
so, for 1 pound = 5.14/4 = $1.285
4) 5-lb bag for $6.20
so, for 1 pound = 6.20/5 = $1.24
In all the four size, the 5 pound bag is cheapest.
Hence, The size of the bag to buy is 5-lb bag for $6.20

If the radius of a circle A is 4 cm and got an area for that circle, if you doubled the radius for circle B would the area be double the area of circle A?
Answer:
No
Step-by-step explanation:
The area won't double by doubling the radius because the radius gets squared and 4^2=16 while 8^2 = 64.

Answer:
width = 15 inches
length = 30 inches
Step-by-step explanation:
Let width = w
Length =2w
Perimeter = 90 inches
2*(length + width) = 90
2*(2w +w ) = 90
2* 3w = 90
6w = 90
w = 90/6
w = 15 units
length = 2*15 = 30 units
