Answer:
f(x) = -1/2x + 1
Step-by-step explanation:
Remember that f(x) = y
f(-2) = 2 tells you that when x = -2, y = 2 ; So you have point (-2, 2)
f(2) = 0 tells you that when x = 2, y = 0 ; So you have point (2, 0)
Now use the two points to find the slope: Slope = (change in y)/(change in x)
So slope = (0-2)/(2-(-2) = -2/4 = -1/2
Next find "b" using the slope and one point and solve for "b"
y = mx + b slope = -1/2 point (-2, 2)
2 = -1/2(-2) + b
2 = 1 + b
1 = b
Last thing to do: write the equation using slope = -1/2 and b = 1 into y = mx + b
y = -1/2x + 1

What are the values of s and t?
Answer:
t= 38°; s=104°
Step-by-step explanation:
ΔHJI is isosceles
Therefore, m∠H ≅ m∠I
m∠I=38°
m∠t (m∠H)=38°
Using the Δ Angle Sum Theorem (all 3 angles of a triangle add up to 180°),
Add m∠H and m∠ I to get 76,
Subtract 76 from 180°
Get 104° as the m∠s
Hope this helps

Step-by-step explanation:
You have agreed to borrow $50 and after six months you pay back $58. How much interest are you paying? What is the interest rate?
Answer:
interest: 8 interest rate: 16
Step-by-step explanation:
the interest is 8$ since you payed 8$ extra, the interest rate can be counted in another way but I forgot it. So 50 is 100%, you divide it by 100 and get 0.5. then you take 8/0.5 which means how many percent there is in 8 which is 16.
This can be solved much easier if you multiply by 2. you borrow 100 and get 116 in return. both interest and interest rate is 16
The interest is $8 and rate of interest is 16%.
What is interest?Using the interest rate formula, we get the interest rate, which is the percentage of the principal amount, charged by the lender or bank to the borrower for the use of its assets or money for a specific time period. The interest rate formula is
Interest Rate = (Simple Interest × 100)/(Principal × Time).
Given:
Interest = $58 - $50 = $8
Time = 6 months = 1/2 hours
Principal = $50
rate = ?
Thus, the rate of interest
= 8 x 100 / 50
=800 /50
= 16%
Hence, the interest is $8 and rate of interest is 16%.

what are intergers and rational numbers? How are the points graphed on a coordinate plane?
Answer:
here you go
Step-by-step explanation:
As we said, points on the coordinate plane are represented as (a, b), where a and b are rational numbers. Rational numbers are numbers that can be written as a fraction, p/q, where p and q are integers. We call a the x-coordinate of the point and we call b the y-coordinate of the point.
Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation.
(-3,-2); y = - 4x + 5
Answer:
y=-4x-14
Step-by-step explanation:
Lines that are parallel would have the same slope, so the slope is
m= -4
Use point slope equation to solve for the slope intercept equation.
y-y1=m(x-x1)
m= -4
x= -3
y= -2
y-(-2)=-4(x-(-3))
y+2=-4x-12
y=-4x-14
Kash Register has been told to eat 1,800 calories per day. He was told that 20% of the calories should be fat, 30% of the calories should be protein and 50% of the calories should be carbohydrates.
Using the percentage concept, the amount of fat, protein and Carbonhydrate to be consumed per day are 360, 540 and 900 calories respectively.
We can calculate the amount of calories for each nutrient class per day thus :
Percentage of nutrient × total caloriesCarbonhydrates :
50% × 18000.5 × 1800 = 900
Protein :
30% × 18000.3 × 1800 = 540
Fat :
20% × 18000.2 × 1800 = 360
Hence, the amount of fat, protein and Carbonhydrate to be consumed per day are 360, 540 and 900 calories respectively.

Answer:
They are all correct
Step-by-step explanation:
c^2 = a^2 + b^2 = pythagorean theorem
if subtract b^2 from both sides = a^2 = c^2 - b^2
if subtract a^2 from both sides then square root both sides = b = sqrt(c^2 - a^2)

(–4, 1)
(4, –1)
(–4, –1)
(4, 1)
Step-by-step explanation:
3x - 4y = 16
-4y = 16 - 3x
y = -(16 - 3x)/4
2x + 3y = 5
2x + -3(16 - 3x)/4 = 5
(8x - 48 + 9x)/4 = 5
17x - 48 = 20
17x = 68
x = 68/17
x = 4
3x - 4y = 16
3(4) - 4y = 16
12 - 4y = 16
-4y = 4
y = 4/-4
y = -1
Solution = (4,-1)

how to simplify 4a-3b+6a
Step-by-step explanation:
very simple : the terms with the same base (either a specific number or a variable with the same exponent, or a function ...) can be combined.
4a - 3b + 6a
which terms here have the same base ?
ah, 4a and 6a refer to the same variable (and with the same exponent : 1, as a = a¹).
therefore, I can combine them :
4a + 6a = a×(4+6) = a×10 or simply 10a
so the result is
10a - 3b
