Slope-intercept form: y = mx + b
11. [tex]y=\frac{2}{5}x+1[/tex]
12. 3x - 7y = 28
Subtract 3x from both sides;
-7y = -3x + 28
Divide both sides by -7
[tex]y = \frac{3}{7} x-4[/tex]
13. [tex]y+4=\frac{1}{2}(x+1)[/tex]
Distribute;
[tex]y+4=\frac{1}{2}x+\frac{1}{2}[/tex]
Subtract 4 from both sides;
[tex]y=\frac{1}{2}x-\frac{7}{2}[/tex]

Rita drove 320 miles using 12 gallons of gas. At this rate, how many gallons of gas would she need to drive 296 miles?
Answers
Answer:
11.1 gallons
Step-by-step explanation:
So, Abdul drove 320 MILES using 12 GALLONS, how many gallons will he need to drive 296 MILES. This can be represented mathematically by;
320 miles=12 gallons
296 miles=x
I replaced the unknown value with the letter x to make it easier to identify. Anyway, you need to cross and multiply. So 296 will multiply 12 and 320 will multiply x.
296 multiplied by 12 is 3552 and 320 multiplied by x is 320x. So;
3552=320x
Divide the both sides by 320 to reveal the value of x. 320 divided by 320 is x. And 3552 divided by 320 is 11.1. So;
x=11.1 gallons of gas
Answer:
11.1
Step-by-step explanation:
CROSS multiple
320/ 12 = 296 / x
x= 11.1

Step-by-step explanation:
By the remainder theorem, the value 2 is a root of P(x) because P(2) = 0
What are the roots of a function?The roots of a function are the zeros of the function
The equation of the function is given as:

Calculate P(2) and P(-2)
[tex]P(2)= \sqrt{2-2} = 0[/tex]
[tex]P(-2)= \sqrt{2-(-2)} = 2[/tex]
Since P(2) = 0, then the value 2 is a root of P(x)

Given
[tex]AC = 2x + 8[/tex]
[tex]AB = 4x - 16[/tex]
[tex]BC = 3x - 6[/tex]
Required
Find AC
First, we need to solve for x
Since B is between A and C, then
[tex]AC = AB + BC[/tex]
Substitute values for AC, AB and BC
[tex]2x + 8 = 4x - 16 + 3x - 6[/tex]

[tex]2x - 4x - 3x = -16 - 6 - 8[/tex]

8.9k
Step-by-step explanation:
We just have to add together the length of the three sides to find the perimeter of the triangle.
(1.8k-5)+(3.5+6.1k)+(k+1.5) = 1.8k-5+3.5+6.1k+k+1.5

What is the length of the sides of kite ABCD? Find the lengths of side AB and side CD. AB = 20; CD = 15 AB = 15; CD = 20 AB = 9; CD = 16 AB = 24; CD = 25
Answers
Answer:
AB = 15; CD = 20
Step-by-step explanation:
The question is attached.
A kite is a quadrilateral (four sides) with two pairs of equal sides which are adjacent to each other. A kite has two diagonals and the longer diagonal bisects the shorter diagonal.
We can use Pythagoras theorem to find the length of the kite sides:
AB² = 12² + 9²
AB² = 225
Taking square root of both sides:
AB = 15
AB = BC = 15 (adjacent sides of a kite are equal)
CD² = 12² + 16²
CD² = 400
Taking square root of both sides:
CD = 20
CD = AD = 20 (adjacent sides of a kite are equal)
