Subsitutey=4x-1 y=-3x-8

Mathematics
1 answer:
Usimov [2.4K]3 years ago
6 0

Answer:

x = -1

y = -5

Step-by-step explanation:

Because we have an equation for the value of y, we can do this:

4x - 1 = -3x - 8

Then we can solve for x.

4x = -3x - 7 --- add 1 to both sides

7x = -7 --- add 3x to both sides

x = -1 --- divide both sides by 7.

Now that we know the value of x, we can solve for y.

y = 4(-1) - 1 --- plug in x

y = -4 - 1 --- simplify

y = -5 --- simplify

Now we know x and y.

x = -1

y = -5

The radius r of a circle can be written as a function of the area A with the following equation: r= sqrt(A/pi) What is the domai
Zepler [3.9K]
The domain of the function is \[A \ge0\] If A is negative we get an imaginary number for the radius. This makes sense because the area of a circle cannot be negative.

What is x/13-5=25/26
Juliette [100K]

\frac{x}{13} -5=\frac{25}{26}    Add 5 on both sides

\frac{x}{13}=\frac{25}{26}+5    Make the denominators the same

\frac{x}{13}=\frac{25}{26}+\frac{130}{26}

\frac{x}{13}=\frac{155}{26}    Multiply 13 on both sides

(13)\frac{x}{13}=(13)\frac{155}{26}

x=\frac{2015}{26}

x=\frac{155}{2}

Daniella collected 4242 bushels of peas from her garden today. Tomorrow she will send \frac{3}{7} 7 3 ​ of the peas to market. H
Vaselesa [24]

Answer: 24

Step-by-step explanation:

Amount of bushels of peas collected = 42

Fraction that'll be sent to market = 3/7

Fraction that'll be kept = 1 - 3/7 = 7/7 - 3/7 = 4/7

The number of bushels that'll be kept will be:

= Fraction that'll be kept × Total number of bushels collected

= 4/7 × 42

= 24
