Answer:
y=4x+3
Step-by-step explanation:
y=mx+b
m-slope
b-y-intercept
slope is 4/1 rise 4 ,run 1
m=4/1=4
y-intercept is 3
Answer:
Slope = 4
y-intercept = 3
Step-by-step explanation:
1. Find the slope
The slope of the line is the change in the line, it is also known as the [tex]\frac{rise}{run}[/tex]. It can be found by using the formula; [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]. On the graph, one can see that points ( -1, -1 ) and ( -2, -5 ). Substitute these into the formula and solve for the slope;
[tex]=\frac{y_2 - y_1}{x_2 - x_1}\\\\=\frac{(-5) - (-1)}{(-2) - (-1)}\\\\=\frac{-5 + 1}{-2 + 1}\\\\=\frac{-4}{-1}\\\\= 4[/tex]
The slope of the given line is 4
2. Find the y-intercept
The y-intercept is where the graph of the line intersects the y-axis. In this case, this point is visible, the point at which the graph intersects the y-axis is (0, 3). The y-intercept is the y-coordinate of this point, in other words (3).

Jessica has saved $50. She will add $25 to her savings each week. Ron has saved $40 and will add $25 to his savings each week.
How much will each person have saved after 5 weeks?
Answers
Answer:
Jessica will have saved $175, and Ron will have saved $165.
Step-by-step explanation:
Jessica starts out with $50. She adds $25 each week, and it's asking how much money she would have in 5 weeks. So, you multiply $25 by 5 to get $125. Then, you add $50 to that to get $175. Same thing for Ron. Multiply $25 by 5 to get $125, but this time add $40 to it to get $165.
Answer:
Jessica- $175
Ron- $165
Step-by-step explanation:
Jessica starts with $50 so put that aside and then it says that she adds $25 EVERY WEEK so how much is she going to have in 5 weeks? 5 x $25 is $125 and now add the $50 which will equal $175
In Ron is the same thing but rather than adding $50 add $40 and it will equal $165

What is the value of x? Answer must be in decimal form 1.5x + 4 = 2.3x - 1.2
I need help
Answers
Answer:
x = 6.5
Step-by-step explanation:
1.5x - 2.3x + 4 = 1.2
1.5x - 2.3x = -1.2 - 4
-0.8x = - 1.2 - 4
-0.8x = -5.2
divide both sides of the equation by -0.8
x = 6.5 :)

Find the perimeter. The shape consists of a square and a half circle. Solve
Answers
Answer and Step-by-step explanation:
We have 3 sides of a square on the outside, so 2 + 2 + 2 equals 6. This is part of the perimeter.
Now we find the circumference of half the circle.
Radius of 1, So the circumference for half of this circle is pi, or 3.14.
So, the answer is 3.14 + 6, which equals 9.14.
The perimeter of the shape is 9.14.

Maya purchased a car on installment scheme for 9 months she paid down payment of DHS. 200 what will be the total cost of car if she pays DHS.275.60 for 9 moths?
Answers
Answer:
The total cost of the car would be DHS$2,680.40.
Step-by-step explanation:
Given that Maya purchased a car on installment scheme for 9 months and she paid down payment of DHS$200, to determine what will be the total cost of the car if she pays installments of DHS$275.60 for 9 months, the following calculation must be performed:
200 + (275.60 x 9) = X
200 + 2,480.40 = X
2,680.40 = X
Thus, the total cost of the car would be DHS$2,680.40.

Find the length of side a?
Answers
Answer: 5
Step-by-step explanation:
For this question you will have to use pythagoras' theorem.
The formula for the short side is a²=c²-b² and when you put the numbers from this question into it you get a²=13²-12²
13²=169
12²=144
a²=169-144
a²=25
Then as you want to find a on it's own you have to square root 25 which is 5.
