Find the gradient and intercept on the x and y axes of the straight line with the following equation.

PilotLPTM [1.2K]

Answer:

gradient is 5

Step-by-step explanation:

x intercept, replace y with 0

y +5x= 13

0+ 5x =13

0 - 13= -5x

-13= -5x

-13/-5 = -5x/-5

x = 13/5

y intercept, replace x with 0

y+5x=13

y+5(0)=13

y+0=13

y =13

Please I need help would mean a lot to me <br><br> 1. If f(x)=x+12and g(x)=x-5,find f(x).g(x).

DerKrebs [107]

F(x) multiplied by g(x)
=
(x+12)(x-5)
Here you need to use the FOIL method (first, outside, inside, last)

Answer: x^2 - 5x + 12x - 60

Coefficient of x^2(px^2+4x+r)×(4x^2-3qx-5)

tankabanditka [31]

Step-by-step explanation:

left side of the expression has an x^2 term, x term and constant(x^0 term), same for the right side of the expression

x^2 coefficient = p(-5) + 4(-3qx) = -5p -12qx

aylor and Natsumi are making block towers out of large and small blocks. They are stacking the blocks on top of each other in a

frozen [14]

Answer:

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x i the height of a large block.

y is the height of a small block.

Taylor uses 4 large blocks and 2 small blocks to make a tower 63.8 inches tall.

This means that:

$4x + 2y = 63.8$

Simplifying by 2:

$2x + y = 31.9$

$y = 31.9 - 2x$

Natsumi uses 9 large blocks and 4 small blocks to make a tower 139.8 inches tall.

This means that:

$9x + 4y = 139.8$

Since $y = 31.9 - 2x$

$9x + 4(31.9 - 2x) = 139.8$

$9x + 127.6 - 8x = 139.8$

$x = 12.1$

$y = 31.9 - 2x = 31.9 - 2(12.1) = 7.7$

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.
