Find the gradients of lines A and B.

Mathematics
1 answer:
pishuonlain [190]3 years ago
4 0

Answer:

Gradient of line A = 4

Gradient of line B = -2

Step-by-step explanation:

To solve this question, we will use the formula for gradient passing through two points (x_1,y_1) and (x_2,y_2),

Gradient (m) = \frac{y_2-y_1}{x_2-x_1}

For line A,

Since, line A passes through (3, 6) and (4, 10)

Gradient of line A = \frac{10-6}{4-3}

                              = 4

For line B,

Since, line B passes through (1, 6) and (2, 4),

Gradient of line B = \frac{6-4}{1-2}

                             = -2

A sporting goods store offers 40% discount on all golf clubs. Rocco spent 20% of the money in his savings account on a golf putt
MatroZZZ [7]

Answer:

Rocco doesn't have enough money to buy the golf irons

Step-by-step explanation:

step 1

Find the rest of the money left in the savings account

using proportion

\frac{\$48}{20\%}=\frac{x}{80\%}\\ \\x=48*80/20\\ \\x=\$192

step 2

we know that

The set of golf irons has an original price of $359

Applying 40% discount

100%-40%=60%=60/100=0.60

after the discount the price will be

0.60(\$359)=\$215.4

\$215.4> \$192

therefore

Rocco doesn't have enough money to buy the golf irons

When the leading coefficient is 1,
If the constant ( c term) is a perfect square and the b term is 2* the square root of the c term.
Ex.
x*2 + 10x + 25
2*5 = 10 5*5=25
Ex.
x^2 - 12x + 36
2 * -6 = -12 6*6=36
