Answer:

$\boxed{\ the \ corresponding\ point\ is \ (-6,7)\ }$

Step-by-step explanation:

We know that f(-2)=7

x+4 = -2 <=> x = -6

so f(-6+4) = f(-2)=7

then the corresponding point is (-6,7)

Answer:

y = 1/2

x = -3/2

Step-by-step explanation:

y = 3x+5

Substance instances of y in the equation.

x + 3x +5 = -1

4x=-6

x= -6/4

y = 1/2

The difference in age between Brita and her daughter Eva is 30 years. The sum or their ages is 118. How old is Eva?

seraphim [82]

Answer: 44 years

Step-by-step explanation:

Let Brita's age be x and the daughter's age be y , then from the first statement :

$x - y = 30$

From the second statement :

$x + y = 118$

solving the resulting linear equation , add the two equations , we have

$2x = 148$

$x = 74$

substitute 74 into equation 1 to find the value of y

$74- y = 30$

$y = 74 - 30$

$y = 44$

Therefore :

Eva = 44 years

Answer:

The numbers are 20 and 140

Step-by-step explanation:

The question in English is

Find 2 numbers knowing that the second number is 7 times greater than the first, and the sum between the double of the first number and the triple of the second is 460

Define the variables

Let

x ----> the first number

y ----> the second number

we know that

$y=7x$ -----> equation A

$2x+3y=460$ ----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B

$2x+3(7x)=460$

solve for x

$2x+21x=460$

$23x=460$

$x=20$

Find the value of y

$y=7x$ ----> $y=7(20)=140$

The numbers are 20 and 140

Find the measurement of X.

Sliva [168]

Since this is a scalene triangle, two sides will equal the same, meaning two angles will equal the same. So 70 has an equal on the other side, meaning 70+70=140, and x will equal the remainder, meaning x=40.

Hope that helps.
