y = ax + b

y = -7

x = 10

-7 = a.10 + b

10a + b = -7

We can put some random values, if a = 1

10.1 + b = -7

10 + b = -7

b = -7 - 10

b = -17

So, we can say that the equation y = x - 17 pass through (10, -7)

What is the value of x and how do you know

Nookie1986 [14]

Answer:

x=35°

Step-by-step explanation:

So first, recall that the interior angles of a triangle must total 180°.

The sum of the angles for the given triangle can be described by:

$110+x+x\\=2x+110$

Since the total must equal 180°, set the expression equal to 180°.

$2x+110=180$

To find the value of x, we just need to solve for x.

To start, subtract 110 from both sides. The 110s on the left cancels:

$(2x+110)-110=(180)-110\\2x=70$

Now, divide both sides by 2. The 2s on the left cancel.

$\frac{(2x)}{2}=\frac{(70)}{2}\\ x=35 \textdegree$

Therefore, the value of x is 35°.

Mr. Martin's math test, which is worth 100 points, has 35

AlekseyPX

Number of questions worth 5 points = 10

Number of questions worth 2 points = 25

Further explanation:

The given system is a system of linear equations in two variables.

We will use the subsitution method to solve the system

Given equations are:

$x+y=35\\5x+2y=100$

From equation no 1:

$x+y=35\\x=35-y$

Putting x=35-y in second equation

$5x+2y=100\\5(35-y)+2y=100\\175-5y+2y=100\\-3y=100-175\\-3y=-75\\\frac{-3y}{-3}=\frac{-75}{-3}\\y=25\\Putting y=25 in first equation\\x+25=35\\x= 35-25\\x=10$

Hence,

Number of questions worth 5 points = 10

Number of questions worth 2 points = 25

velikii [3]

<span>First, we need to know that the current recommended daily allowance of Vitamin E is 15 milligrams. If Leena ate four tablespoons of peanut butter, thus receiving only 6 milligrams, then we can determine the percentage by first dividing 100 into 15 parts (which gives us 6.66), and then multiply that answer by 6 (6 x 6.66), which gives us precisely 40. Thus, the answer is 40 percent.</span>
