SOMEONE PLSSS HELPPPPPP!!!!!!!! Graphing an Inequality
fiasKO [112]

Answer:

An inequality can be represented graphically as a region on one side of a line. Inequalities that use < or > symbols are plotted with a dashed line to show that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to show that the line is included in the region.

28 + 24 as a product of two factors using the GCF and the distributtive property
Sloan [31]

Answer:

28 + 24 as a product of two factors is 4(7 + 6)

Step-by-step explanation:

GCF is the greatest common factor of two numbers

Let us find the GCF of the given numbers 28 and 24

∵ 28 = 1 × 28, 2 × 14, 4 × 7

∴ The factors of 28 are 1, 2, 4, 7, 14, 28

∵ 24 = 1 ×24, 2 × 12, 3 × 8, 4 × 6

∴ The factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24

→ Find the common factors of them

∵ The common factors of 28 and 24 are 1, 2, 4

∵ The greatest factor of them is 4

∴ The GCF = 4

→ Write 28 as 4 × 7 and 24 as 4 × 6

∵ 28 = 4 × 7 and 24 = 4 × 6

∴ 28 + 24 = 4 × 7 + 4 × 6

→ Take 4 as a common factor

∵ 4 × 7 + 4 × 6 = 4(7 + 6) ⇒ distributive propoerty

∴ 28 + 24 = 4(7 + 6)

∴ 28 + 24 as a product of two factors is 4(7 + 6)

One meter of electrical cord costs 3 dollars. How much should one pay for 4 meters?? Please help me out here.
Snowcat [4.5K]

Answer:

$12

Step-by-step explanation:

The best way to do this is with a simple ratio. If you pay $3 for one meter, then for 4 meters, you’d pay $12. You BOUGHT 4 times more cord, which means you’d PAY 4 times more. Thus, 3 x 4 = 12!

Or with ratios:

1 meter : $3

multiplying both sides by 4

4 meters : $12

Eliminate the parameter.<br><br> x = 3 cos t, y = 3 sin t
ElenaW [278]

Answer:

x^2+y^2 = 3^2

Step-by-step explanation:

We need to eliminate the parameter t

Given:

x = 3 cos t

y = 3 sin t

Squaring the above both equations

(x)^2=(3 cos t)^2

(y)^2 =(3 sin t)^2

x^2 = 3^2 cos^2t

y^2=3^2 sin^2t

Now adding both equations

x^2+y^2=3^2 cos^2t+3^2 sin^2t

Taking 3^2 common

x^2+y^2=3^2 (cos^2t+sin^2t)

We know that cos^2t+sin^2t = 1

so, putting the value

x^2+y^2=3^2(1)

x^2+y^2 = 3^2

Hence the parameter t is eliminated.
