Answer:
y = (3/2)x + 7
Step-by-step explanation:
(−4, 1) and (−2, 4)
slope m = rise/run = (4-1)/(-2-(-4)) = 3/2
Slope intercept form is y=mx+b
where m=slope, b = y-inercept
y = (3/2)x + b
Use one of the given points for (x,y) to find b
1 = (3/2)(-4) + b
1 = -6 + b
7 = b
y = (3/2)x + 7
Answer:
<em>The width is 4 cm</em>
<em>The length is 12 cm.</em>
Step-by-step explanation:
<u>Area of a rectangle</u>
Given a rectangle of width W and length L, its area is calculated as follows:
The area of the given rectangle is 48 cm^2, and the length is three times the width, thus:
L = 3W
Substituting into the formula of the area:
Simplifying:
Solving:
The width is 4 cm. Find the length:
L=3W=3*4= 12
The length is 12 cm.
The image attached shows the rectangle on the centimeter grid
Answer:
1.7 units
Explanation:
The length of an arc is calculated using the formula below:
Substitute the given values of θ and r:
The length of the arc is 1.7 units.
Answer:
2250
Step-by-step explanation:
We have, 14% × x = 315
or,
14
100
× x = 315
Multiplying both sides by 100 and dividing both sides by 14,
we have x = 315 ×
100
14
x = 2250
If you are using a calculator, simply enter 315×100÷14, which will give you the answer
Answer:

Step-by-step explanation:
This is a little complicated but base e which means Euler's number is usually used when solving logarithms. base e equals to 2.71828. You can kind of compare this to pi. This is an irrational number and usually is used in natural logs. I hope this helps.
