IV. Intercepts. Give the intercepts of the following linear equations. 1) 5x + 3y = 8 2) 10x + 6y - 12 = 4 3) 2x – 3y = 5 4) 3x

rosijanka [135]

Answer:

1) $\frac{8}{3}$

2) $\frac{8}{3}$

3) $\frac{-5}{3}$

4)2

Step-by-step explanation:

1) 5x + 3y = 8

3y=8-5x

$y=\frac{-5}{8} x+\frac{8}{3}$

hence intercept is $\frac{8}{3}$

2) 10x + 6y - 12 = 4

10x + 6y = 16

6y=16-10x

$y=\frac{-10}{6} x+\frac{16}{6}$

hence intercept is $\frac{8}{3}$

3) 2x – 3y = 5

3y=2x-5

$y=\frac{2}{3} x+\frac{-5}{3}$

hence intercept is $\frac{-5}{3}$

4) 3x + 2y = 1

2y=-3x+4

$y=\frac{-3}{2} x+\frac{4}{2}$

hence intercept is 2

What is the solution to 11 = x – 4?

marishachu [46]

Well to find out X, you have to do the opposite to what it's asking to each side. So 11=x-4

+4 onto the 11 and + 4 on to the -4 which means you just have 15=X

Bob installed new windows in his house which were advertised to cut his energy bill by 7.1% per month after installation. If his

maxonik [38]

His monthly bill before he installed the new windows was $339.074...

<u><em>Explanation</em></u>

Suppose, his monthly bill before he installed the new windows was $x$ dollar.

As his energy bill was decreased by 7.1% per month after installation, so <u>the amount of bill decreased</u> $=x*\frac{7.1}{100}=0.071x$ dollar

Given that, his new energy bill was $315. So the equation will be...

$x-0.071x= 315\\ \\ 0.929x=315\\ \\ x=\frac{315}{0.929}=339.074....$

So, his monthly bill before he installed the new windows was $339.074...

The dimensions of a triangle are shown below. If the height of the triangle is increased by the factor of 4, which statement wil

Varvara68 [4.7K]

Answer:

Option B. The area will increase by a factor of 4

Step-by-step explanation:

we know that

The area of triangle is equal to

$A=\frac{1}{2}bh$

where

b is the base of triangle

h is the height of triangle

If the height of the triangle is increased by the factor of 4

then

The new area of the triangle will be

$Anew=\frac{1}{2}b(4h)$

$Anew=4[\frac{1}{2}bh]$

$Anew=4[A]$

The new area is 4 times the original area

therefore

The area will increase by a factor of 4
