NO ONE IS HELPING PLEASE. Find the value of x in each case! IF U GET THIS I WILL MARK BRAINLIEST. 25 POINTS ON THE LINE! Thank y
Murrr4er [49]

Answer:

11  

Step-by-step explanation:  

Use corresponding angles.  

Angle FBC is 180 - 147 which is 33.  

This means x is 180 - 33 - Angle EBA.  

EBA is 180 - 4x.  

x = 180 - 33 - (180 - 4x)  

x = 180 - 33 - 180 + 4x  

-3x = 180 - 33 - 180  

-3x = -33  

3x = 33  

x = 11  

Please mark brainliest.

A sum of money invested at the compound interest payable yearly has interest in
jeka94

Answer:

49% and 30% respectively

Step-by-step explanation:

Step one:

Given data

Principal =  Rs. 4,200

Final Amount= Rs. 9282 respectively

time = 2 years and

time = 4 years

Required

The rate of interest for 2 and 4 years

Step two:

the compound interest formula is

A= P(1+r)^t

for 2 years

Substitute

9282= 4200(1+r)^2\\\\9282/4200= (1+r)^2

1+r= \sqrt{\frac{9282}{ 4200} }\\\\1+r= \sqrt{2.21} \\\\1+r= 1.49\\\\r=1.49-1\\\\r= 0.49\\\\

the rate is 49%

For 4 years we have

9282= 4200(1+r)^4\\\\9282/4200= (1+r)^4

1+r= \sqrt[4]{\frac{9282}{4500} } \\\\1+r=\sqrt[4]{2.21}  \\\\1+r= 1.30\\\\r=1.30-1\\\\r= 0.30\\\\

the rate is 30%

Find the equation of the line through point (−4,−4) and perpendicular to 2x+3y=3. Use a forward slash (i.e. "/") for fractions (
Mandarinka [93]

Answer:

y = 3/2x + 2

Step-by-step explanation:

Step 1: Write original equation into slope-intercept form

3y = -2x + 3

y = -2/3x + 1

Step 2: Find slope of perpendicular line

Take the negative reciprocal of the other slope.

m = 3/2x

Step 3: Find <em>b</em>

y = 3/2x + b

-4 = 3/2(-4) + b

-4 = -6 + b

b = 2

Step 4: Rewrite perpendicular equation

y = 3/2x + 2
