40 by 2.5 ?
Step-by-step explanation:
Answer:
Step-by-step explanation:
To find the equation of the line in slope-intercept form we to find the y-intercept(b) and the slope(m)
For the y-intercept(b) we can see that the line crosses/intersects the y-axis at 40 so the value of b equals 40 which means our y-intercept is 40
now all that is remaining is the value of m which we can find through the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
we take any two coordinates which lie on the line for example
(0 , 40) and (2 , 140) and plug it into our formula
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{140-40}{2-0}\\\\m=\frac{100}{2} \\\\m=50[/tex]
so the slope of the line is 50 which is m , so the equation of the line in slope-intercept form would be:
[tex]y=mx+b\\y=50x+40[/tex]

Answers
Answer:
m=-20
Step-by-step explanation:
You do the reverse operation on the 4. The opposite of +4 is -4. You subtract -4 on both sides so your left with m on one side and -20 on the other side. -16 - 4 = -20

During an exploratory activity, a student measured the diameter and circumference of several circular objects. She recorded her data in the table below. What equation best represents this data?
y = 6.28x
y = 3.14x + 6.28
y = 3.14x
y = 6.28x + 3.14
Answers
Answer:
y=3.14x
Step-by-step explanation:
if you graph this on a calculator you can just visually see what line lines up with all the points. but you can also plug in one of the points into the equations to see if its true or not and if its true choose that equation. like use the first points (2, 6.28) and plug them into the equations and see which one is true.
The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.
Given that, a student measured the diameter and circumference of several circular objects.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
From the table we have (2.0, 6.28) and (5.3, 16.64)
Now, slope = (16.64-6.28)/(5.3-2.0)
= 10.36/3.3
= 3.14
Substitute m=3.14 and (x, y)=(2.0, 6.28) in y=mx+c, we get
6.28=3.14(2.0)+c
c=0
Substitute m=3.14 and c=0 in y=mx+c, we get
y=3.14x
The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.

Answer: 2.3 × 0.4 = 0.92 .
2.3 × 1 = 2.3
0.92 + 2.3 = 3.22
Step-by-step explanation:
When decimal points are left out until the end, you can count the number of decimal places to the right of the decimals in the factors and then insert the decimal in the product, counting places right to left.
The factor 2.3 has one decimal place. The factor 0.4 has one decimal place.
Thats a total of 2.
92 becomes .92 when the decimal is inserted two places to the left.
230 becomes 2.30 when the decimal is inserted two places to the left.

Answer:
∡ABC=55°
Step-by-step explanation:
Step 1: Identify all angles
∠A=(x+45)°
∠B=(6x+5)°
∠C=(3x)°
∠ABC=(180-∠B)°=(180-(6x+5))°
Step 2: Use the Triangle Angle Sum Theorem
∠A+∠ABC+∠C=180°
(x+45)+(180-(6x+5))+(3x)=180
x+45+180-6x-5+3x=180
-2x+45+180-5=180
-2x+45-5=0
-2x+40=0
-2x=-40
x=20
Step 3: Plug in x=20 for ∠ABC
∠ABC=(180-(6x+5))°
(180-6(20)-5)°
(180-120-5)°
(60-5)°
55°
So ∡ABC=55°
Answer:
∡ABC=55°

-2x+45-5=0
-2x+40=0
-2x=-40
x=20
Step 3: Plug in x=20 for ∠ABC
∠ABC=(180-(6x+5))°

A photographer is making an enlargement of a color portrait. If the original portrait is 11 inches by 14 inches and he wants to make the new width 14 inches, about how long should the enlarged length be?
Answers
The width of the original is 11 inches.
The ratio of the width is 14/11
Set up a ratio for the new length:
14/11 = 14/X
Cross multiply:
11x = 196
Divide both sides by 11:
x = 196/11
x = 17.8 inches. (Rounded to the nearest tenth)
Answer:
Original width: 11 inches.
ratio: 14/11
