Does the point (5, 7) lie on the line y = −3x + 22

Answer:

a.

Step-by-step explanation:

It says 13+, so it’s 13 more than.
Then it’s 1/2 *, so it’s half of whatever’s next.

Next, it’s 6/2, so it’s a quotient because it’s divided.
Last, it says +6, so it’s 6 more than the last term.
Finally, 13 more than half of 6 more than the quotient of 6 and 2.

Advice: write out each step in words before you put it together.

Answer:

13 more than half of 6 more than the quotient of 6 and 2

Step-by-step explanation:

13 more than half of 6 more than the quotient of 6 and 2

Step-by-step explanation:

4x - 6 = 2x + 4

2x = 10

x = 5

y = 2x + 4

y = 2(5) + 4

y = 14

Answer:

African American culture is correct !

Answer:

y + x + 90°=180°( sum of triangle=180°/Angeles of a triangle are supplementary)

y + x=180°-90°

there for x=y (Given by the theorem) OR two opposite angles of a triangle are equally

x+x= 90°/y+y=90° Note: Since y=x then sub y by x or y instead of the same equition (y=x)

x+x/y+y=90°

2x=90°

x=45°

or

x+y=90°

45+y=90°

y=90°-45°

y=45°

Step-by-step explanation:

7.296 × 10² / 9.6 × 10^ -9

= 0.76 × 10^11

= 7.6 × 10^10

Answer:

angle V equals 103 degree.

Step-by-step explanation:

Based on the supplementary rule for a line is 180 degree.

We have to minus 147 from 180 to find the missing angle X that's inside the triangle.

180-147=33

For each triangle, it'll have a total of 180 degree when the angles are added together.

40+33+___=180

Answer:

1 12:37:pm

Step-by-step explanation:

1)

let x = time that they will pass each other

distance travelled = speed * time

distance of train 1 = 70*x

distance of train 2= 90*x

distance travelled is equal to 900km

70x + 90x = 900

160x = 900

x=5.625

convert into hrs, minutes and seconds

5.625 hrs is equal to 5 hrs, 37 mins, and 30 seconds

add this time to 7:00 am to get the answer

Answer:

m∠B= 60°

Step-by-step explanation:

The given triangle has all sides equal, so it's an equilateral triangle.

Equilateral triangle is always equal to 60°

Therefore, m∠B= 60°.

Answer:

(-8, 11/2)

Step-by-step explanation:

1. The midpoint between two points can be found by averaging the x-values of both points and the y-values of both points. For example, if you had the points (x, y) and (m, n), then the midpoint would be ([tex]\frac{x+m}{2}[/tex], [tex]\frac{y+n}{2}[/tex])

2. Calculate your midpoint. In this specific case your x-value would be (-7+-9)/2 and your y-value would be (8+3)/2, or (-8, 11/2)

The values needed for completing the function to match with its graph is [tex]f(x) = -(x+4)(x-3)[/tex]

There are many tools we can use to find the information of the relation which was used to form the graph.

The graph of the considered problem which is missing is attached below.

Let the completed function is

[tex]f(x) = a(x-b)(x-c)\\[/tex]

Then the roots of the function would be the values of x at which the function becomes 0, and they are [tex]x = b[/tex] and [tex]x = c[/tex]

Since the graph crosses the x axis at -4 and 3, therefore, as the points on x axis are the roots of the functions of variable x, therefore, we get:

b and c to be -4 and 3, therefore, the function is

[tex]f(x) = a(x-(-4))(x-3) = a(x+4)(x-3)[/tex]

Since the function crosses the y axis at y = 12, and since on y axis, the value of x is 0, therefore, putting x = 0, and equating the output to 12, we get:

[tex]f(x) = a(x+4)(x-3)\\12 = a \times 4 \times -3\\12 = a \times -12\\\\\text{Dividing both the sides by -12}\\\\\dfrac{12}{-12} = a\\\\a = -1[/tex]

Therefore, the completed function would look like:

[tex]f(x) = -(x+4)(x-3)[/tex]

Thus, the values needed for completing the function to match with its graph is [tex]f(x) = -(x+4)(x-3)[/tex]

Answer:

5 batches of orange paint.

Step-by-step explanation:

Since we only have the amount of red paint Finley has, you have to divide 15 by 3, since we need 3 liters of red paint for 1 liter of orange paint. 15 divided by 3 equals 5, so Finley can only make 5 batches of orange paint when she has 15 liters of red paint.
