Answer:
B
Step-by-step explanation:
6x-7=26
6x=33
x=5.5
Answer:
y=2x
Step-by-step explanation:
If the line is parallel to 4x-2y=6, it means that it has the same slope. So let's first find the slope.
Rearranging, we get
-2y=-4x+6
2y=4x-6
y=2x-3.
So, the slope is 2.
Next, we can use the point slope formula
y-y_1=m(x-x_1)
Substituting, we get
y-2=2(x-1)
y-2=2x-2
y=2x
Answer:
Note that the line has a y-intercept at (0, 2), with slope m=1 m = 1 . Example 6: Find the equation of the line passing through (−1, 3) and (5, 1). Solution: First, find m, the slope. Given two points, use the slope formula
Answer:
x = 2.7
Step-by-step explanation:
-1.2x + 11.45 = 8.21
Subtract 11.45 from both sides to get -1.2x = -3.24.
Divide both sides by -1.2 to get x = 2.7.
Answer:
C: 13cm
Step-by-step explanation:
Given;
length of the rectangle, L = (x + 4) cm
width of the rectangle, W = 
cm
perimeter of the rectangle, P = 35 cm
The perimeter of a rectangle is given as;
P = 2(L + W)
Substitute the givens;
![35 = 2[(x+ 4) + \frac{2x}{4} ]\\\\35 = 2[\frac{6x}{4} +4]\\\\35 = 3x+8\\\\3x = 27\\\\x = \frac{27}{3}\\\\x = 9](https://tex.z-dn.net/?f=35%20%3D%202%5B%28x%2B%204%29%20%2B%20%5Cfrac%7B2x%7D%7B4%7D%20%5D%5C%5C%5C%5C35%20%3D%202%5B%5Cfrac%7B6x%7D%7B4%7D%20%2B4%5D%5C%5C%5C%5C35%20%3D%203x%2B8%5C%5C%5C%5C3x%20%3D%2027%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7B27%7D%7B3%7D%5C%5C%5C%5Cx%20%3D%209)
Then, L = (x + 4) cm
L = (9 + 4) cm
L = 13 cm
Therefore, the length of the rectangle is 13 cm
