Write in slope-intercept form an equation of the line that passes through the given points.
(−1,4),(3,8)
Answer:
y = x + 5
Step-by-step explanation:
Slope (m) formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{8-4}{3-(-1)}\\\\m=\frac{8-4}{3+1}\\\\m=\frac{4}{4}\\\\m=1[/tex]
y = mx + b
y = 1x + b OR y = x + b
(-1, 4)
y = x + b
4 = -1 + b
+1 +1
5 = b
y = x + 5
Check your answer using y = x + 5 and (3, 8):
y = x + 5
8 = 3 + 5
8 = 8
This statement is true
Therefore, our final answer is, y = x + 5.
Hope this helps!

2. The late fees for a school library are represented by the function
C= 0.25d, where c is the total cost and d is the number of days
a book is late. The fees charged by a city library are shown in the

1.05
Step-by-step explanation:
If you really look at it and do the math the late feels towards the school library contrasts the number of days where the total cost is. Compare it enough and youll get 1.05
Apply the Distributive Property to solve the equation below. What operation will you need to use first? What operation would you need to use last?
6 (t+12) =114
Answer:
See below.
Step-by-step explanation:
6(t+12)=144
6t+72=144
-72 -72
6t=72
/6 /6
t=12
So, multiplication is the first operation used, and division is the last.

.Edward deposited $9,500 into a savings account 3 years ago. The simple interest rate is 4%. How much money did Edward earn in interest?
Answer:
first, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year.
Solving our equation:
A = 6000(1 + (0.03 × 4)) = 6720
A = $6,720.00
The total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 3% per year for 4 years is $6,720.00.
Hope it helps!!!!!!!!brainliest pls!!!!!!!Answer:

deanna bought the poster shown below for her wall if a=11 cm,b=28cm,c=15cm,and d=17cm,what what is the area of the poster
Answer:
409[tex]cm^{2}[/tex]
Step-by-step explanation:
The area of the box wuld be c times d which is 15 times 17 which is 255.
the area of the triangle is [tex]\frac{1}{2}\\[/tex] (base x height) = [tex]\frac{1}{2}\\[/tex](28 x 11) = 14 x 11 = 154
154 + 255 = 409. area of 2D shape's unit is squared, so 409 [tex]cm^{2}[/tex]

Hii :)
We know that there are 2 boys, so we should divide 2 by 43. But first..
We need to add the total amount the boys spent together, then subtract,then divide
13+5=18.
The boys spent a total amount of 18 cents.
Next, we need to subtract 18 by 43.
43-18=25.
So, if we were to spilt the 25 evenly, or divide by 2, the answer would be 12.5 cents. But, we need to find what they had to start with.
43 divided by 2 is 21.5. So each boy had 21.5 cents to start with.
Hope this helps~

3/4 (12a + 8) = 31.2
CHECK THE PHOTO BELOW!!
Answer:
a=2.8
Step-by-step explanation:
Answer:
(3/4 * 12a) + (3/4 * 8) = 31.2
a = 2.8
