Y=2x+10<br> y=x+1 <br> solve using substitution

Anvisha [2.4K]

Answer:

x = -9

y = -8

Step-by-step explanation:

here's the solution :-

=》y = 2x + 10

=》y = x + 1

plunging the value of y from equation 1 into equation 2

=》2x + 10 = x + 1

=》2x - x = 1 - 10

=》x = -9

value of x = -9

now, plugging the value of x in equation 2, we get :-

=》y = x + 1

=》y = -9 + 1

=》y = -8

Please Help!

vlada-n [284]

Answer:

The base is $11\ in$ and the height is $14\ in$

Step-by-step explanation:

we know that

The area of the triangle is equal to

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

where

b is the base of triangle

h is the height of triangle

In this problem

$b=h-3$ ----> equation A

$A=77\ in^{2}$

$77=\frac{1}{2}(b)(h)$

$154=(b)(h)$ -----> equation B

Substitute equation A in equation B

$154=(h-3)(h)$

$h^{2}-3h-154=0$

Solve the quadratic equation by graphing

The solution is $h=14\ in$

see the attached figure

Find the base b

$b=14-3=11\ in$

How to find x (similar triangles)

hammer [34]

Answer:

x = 2

Step-by-step explanation:

Parallel lines divides the transversals in proportion.

Therefore,

$\frac{9}{4} = \frac{13.5}{x + 4} \\ \\ 9(x + 4) = 13.5 \times 4 \\ \\ 9(x + 4) = 54 \\ \\ x + 4 = \frac{54}{9} \\ \\ x + 4 = 6 \\ \\ x = 6 - 4 \\ \\ x = 2$

Rex runs one mile in 5 minutes, Stan runs one mile in 6 minutes, and Tim runs one mile in 7 minutes. There are 5280 feet in one

Brums [2.3K]

Answer:

$628.5ft$

Step-by-step explanation:

Find the velocity of Tim and Stan, by dividing the distance between the time:

$v_T=\frac{5280}{7} =754.3 ft/min$

$v_S=\frac{5280}{6} =880ft/min$

The distance that Stan and Tim travel in 5 minutes is equal to their respective velocity multiplied by the time.

$d_T=754.3\times5=3771.5ft\\$

$d_S=880\times5=4400ft$

The answer to the question is the difference in miles traveled by Stan minus those traveled by Tim.

$R=4400-3771.5=628.5ft$
