help me please 20 pts.

Answer:

Step-by-step explanation:

Y=mx+b

Slope (m) is rise over run.

1. rise= 4 run=5 therefore, slope=4/5

y=4/5x+b

b= y intercept

b= 4

Y=4/5x+4

2. rise= 1 run= 2 slope = -1/2

b= -1

Y= -1/2x - 1

Answer:

20 PERCENT

Step-by-step explanation:

BECUASE 40 INTO 60 AND THAT MEAN WE PLUS 20

Answer:

It would go up by 50%

Step-by-step explanation:divide 60 by 40 to get 1.5

then change that to 50% because the extra 1 is the 60 and then change the  0.5 to 50%

The perimeter of this park based on the x value is equal to 422 m.

Add all the sides of the triangle. This step implies finding the value of x, which is necessary to know the length of two of the three sides.

Assuming both perpendicular sides are equal, x can be expressed as:

This means, the lengths of the sides are:

Answer:

12.5 km/hr

Step-by-step explanation:

You find the mean after making them both the same measurement.

You would divide 10 by 2 to get 5 km/hr

You would use the 20 km/hr

You would add them and get 25

Then divide by 2 to find the mean and get 12. 5

Answer:

We need 8 and 3/4 cups of blueberries to make 7 batches of pancakes.

Step-by-step explanation:

A proportion is basically a statement that says two fractions are equal to each other. It's usually used to state the equivalence of two ratios, and is often in problems such as these, where you need to prove that the ratio of the original two objects are the same as the new two objects.

Let us set x to be the new amount of cups of blueberries.

Hence, we have to find the original ratio first. Let's say we want to use the ratio of cups of blueberries to batches to be the measuring stick (a quick tip would be to see what information is provided for the new ratio and use that information as the denominator). That ratio would be:

[tex]\frac{1 \frac{1}{4}}{1}[/tex]

[tex]= \frac{\frac{5}{4}}{1}[/tex]

[tex]= \frac{5}{4}[/tex]

So, now that we know the ratio of cups of blueberries to batches, we can use that information to construct a proportion:

[tex]\frac{5}{4} = \frac{x}{7}[/tex]

Great! Now it's just a matter of solving this equation:

[tex]\frac{5}{4} = \frac{x}{7}[/tex]

[tex]4x = 5 \cdot 7[/tex]

[tex]x = \frac{35}{4}[/tex]

[tex]x = 8 \frac{3}{4}[/tex]

Finally, we can know that we need 8 and 3/4 cups of blueberries to make 7 batches of pancakes.

Answer:

$2.5

Step-by-step explanation:

Number of pounds of banana needed = 5 pounds

Cost per pound of banana = 0.50

To solve using place value blocks :

Ignoring the decimal in the cost per pound:

We can first take the product of 5 (Number of pounds of banana) and take cost per pound as 5. Since it is easier to make direct multiplication without decimal.

5 * 5 = $25

Now we can add the one decimal point (in the cost per pound) to our result

Then we have $2.5

Hence, total cost = $2.5

Answer:

X = -5

Step-by-step explanation:

3x - 15 = -30       You want to isolate tha variable

3x= -30+15    Add 15 to -15 in order to get rid of it. All you do to one side you do to the other, so you add 15 to 30

3x= -15    

x= -15÷3   Divide x by 3 in order to get rid of the 3. Do it to the other side

x=-5  

Answer:

Laila gets £470

Step-by-step explanation:

Let John's share=x

Laila's share=x+80

The sum of their individual shares should equal 860

therefore x+x+80=860

2x=860-80

2x=780

x=390

Therefore each person's share:

John-£390,Laila-£470

Answer:

My name is Laila

Step-by-step explanation:

share 860 pounds between laila and john so that laila gets £80 more than John. How much does Laila get​

Answer:

y = 2x + 5

Step-by-step explanation:

First, find the slope using rise over run, (y2 - y1) / (x2 - x1)

With this information, we can create 2 points: (2, 9) and (5, 15)

Plug in the points:

(15 - 9) / (5 - 2)

6 / 3

= 2

Plug in the slope and a point into y = mx + b, and solve for b:

y = mx + b

15 = 2(5) + b

15 = 10 + b

5 = b

Plug in the slope and b into the equation:

y = 2x + 5 is the equation of the line

Answer: The bisector of angle F is a line segment from vertex F to the midpoint of line DE.

Midpoint: x = (2+6)/2 = 4; y = (-5+-1)/2 = -3

The midpoint is at (4,-3).

The equation of the line follows the point-slope formula:

y - y₁ = [(y₂ - y₁)/(x₂ - x₁)](x - x₁)

Substituting using points (5,6) and (4,-3)

y - 6 = [(⁻3 - 6)/(4 - 6)](x - 5)

y - 6 = (9/2)(x - 5)

2(y - 6) = 9(x - 5)

2y - 12 = 9x - 45

2y - 9x = -33

Answer:

1 is the y-intercept, the slope is -2/3

Step-by-step explanation:

The B in y=mx+b is always the y intercept and the mx is always the slope.

Answer:

X=-25/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

1/5x+1/2-1/2x=1/2x+3-1/2x

-3/10x+1/2=3

Step 3: Subtract 1/2 from both sides.

-3/10x+1/2-1/2=3-1/2

-3/10x=5/2

Step 4: Multiply both sides by 10/(-3).

(10/-3)*(-3/10)=(10/-3)*(5/2)

X=-25/3
