Determine whether cach point lies on the graph of the line y = 4.6x -7.

H(0, -7)

**Answer:**

Point H does lie on the graph y = 4.6x - 7

**Step-by-step explanation:**

Step 1: Define

y = 4.6x - 7

H(0, -7)

Step 2: Substitute, Evaluate, and Check

-7 = 4.6(0) - 7

-7 = 0 - 7

-7 = -7

**Answer:**

H(0,-7) does lie on the graph of line y = 4.6x - 7

**Step-by-step explanation:**

All you have to do is simply plug in the x and y values.

From the point H (0,-7) we can say that

x = 0

y = -7

Now just plug it into the equation.

y = 4.6x - 7

(-7) = 4.6(0) - 7

-7 = -7

Since -7 does equal -7, the point H is on the line of y = 4.6x - 7.

A school has $15,000 to spend on computer monitors. The school plans to purchase 200 monitors for $89 each. A teacher completes the calculations below and concludes that the school has enough money to buy the monitors. 200 × 89 = (200 × 8) + (200 × 9) = 1,600 + 1,800 = 3,400

Answer:

Since the budget of the school is $15,000, the school does not have enough money to buy the monitors

Step-by-step explanation:

The school plans to purchase 200 monitors for $89 each.

This is the calculation of the teacher

200 × 89 = (200 × 8) + (200 × 9) = 1,600 + 1,800 = 3,400

The teacher's calculation is wrong

The correct calculation using Distributive property is

a(b + c) = ab + ac

200 × 89 = 200(80) + 200(9)

Because 80 + 9 = 89

Hence,

200 × $89 = 16000 + 1800

= $17,800

Since the budget of the school is $15,000, the school does not have enough money to buy the monitors

$17, 800 ≠ $15,000

**Answer:**

3/8 = 0.375

**Step-by-step explanation:**

I used a calculator

for the graph of g(x) pictured below, over which of the following intervals is g(x) only decreasing?

Answer:

2. -8 < x < -2

Step-by-step explanation:

The x-values of the line where the line slants downwards before it begins to slant upwards to the right, is the interval at which g(x) is decreasing only.

From the graph, at x = -8, y = -2. When x = -2, y = -5.

Between the intervals of x = -8 and x = -2, g(x) decreased from -2 to -5.

Therefore, the answer is: 2. -8 < x < -2

**Answer:**

2/3

**Step-by-step explanation:**

Answer:

2/3

Step-by-step explanation:

Slope equals rise/run. You find one perfect point (-2,0) and another along the line (1,2)

You count how many units up (rise) from the first point to the second point, and then you go over (run) to the second point. Your rise over your run is your slope.

A bus and a truck leave a gas station at the same time and are headed to the same destination. If the bus traveled 110 miles in 2 hours, and the truck traveled 180 miles in 3 hours, who is on pace to reach the destination first?

**Answer:**

The truck is on pace.

**Step-by-step explanation:**

To find which truck will arrive first, you need to find each vehicle's mph. To get the mph of each vehicle you just need to divide the distance by time.

Bus: 110 (miles) ÷ 2 (hours) = 55 (miles per hour)

Truck: 180 (miles) ÷ 3 (hours) = 60 (miles per hour)

When you do this you can see the mph of the bus is < the mph of the truck.

4. Evaluate the following expression for r= 5.

2(r2 - 8)

**Answer:**

The expression is equal to 4

**Step-by-step explanation:**

Given the expression 2(r2-8) and the equality for the variable r = 5. It is best to substitute this equality into the expression to solve for its corresponding value:

2(r2-8) =

2(2(r)-8),

2(2(5)-8),

2(10-8),

2(2),

4

What is the solution to the system of equations?

**Answer:**

(2, - 4 )

**Step-by-step explanation:**

Given the 2 equations

x + 2y = - 6 → (1)

3x + y = 2 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the term in y

- 6x - 2y = - 4 → (3)

Add (1) and (3) term by term to eliminate y

- 5x = - 10 ( divide both sides by - 5 )

x = 2

Substitute x = 2 into either of the 2 equations and solve for y

Substituting into (1)

2 + 2y = - 6 ( subtract 2 from both sides )

2y = - 8 ( divide both sides by 2 )

y = - 4

Solution is (2, - 4 )

**Answer:**

**Step-by-step explanation:**

**Answer:**

29c

**Step-by-step explanation:**

Write an equation parallel to 2x+5y=15 that passes through the point (-10,1).

2x + 5y = 15

5y = -2x + 15

y = -(2/5)x + 3

y = mx + b

1 = -(2/5)(-10) + b

1 = 4 + b

-3 = b

So the equation of the line would be:

y = -(2/5)x - 3

5y = -2x + 15

y = -(2/5)x + 3

y = mx + b

1 = -(2/5)(-10) + b

1 = 4 + b

-3 = b

So the equation of the line would be:

y = -(2/5)x - 3

A 42-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is Two inches more than seven times the length of the first piece. Find the lengths of the pieces.

**Answer:**

4, 8, 30

**Step-by-step explanation:**

Let's call the first piece x. If the first piece is x, then the second piece is 2x and the third piece is 7x + 2.

Equation:

x + 2x + 7x + 2 = 42

10x + 2 = 42

10x = 40

x = 4

**The First piece is 4 inches**

Now all we do is substitute the x for 4. Therefore, **the second piece is 8 inches and the third piece is 30.**
