Identity, which basically is any number times 1 will equal that number :)

Use the method of ELIMINATION to solve the system. You must SHOW ALL WORK. Make sure you have an answer for both x and y.

Answer:

<h3>Required <u>Answer</u><u>:</u><u>-</u></h3>

$\sf 4x+8y=10\dots\dots (1)$

$\sf -4x+2y=-30\dots\dots (2)$

by adding eq (1) and eq (2) we get

${:}\longrightarrow$ $\sf 4x+8y=20$

${:}\longrightarrow$ $\sf -4x+2y=-30$

${:}\longrightarrow$ $\sf 10y=-10$

${:}\longrightarrow$ $\sf y={\dfrac {-10}{10}}$

${:}\longrightarrow$ ${\underline{\boxed{\bf y=-1}}}$

Substitute the value in eq (2)

${:}\longrightarrow$ $\sf -4x+2 (-1)=-30$

${:}\longrightarrow$ $\sf -4x-2=-30$

${:}\longrightarrow$ $\sf -4x=-30+2$

${:}\longrightarrow$ $\sf -4x=-28$

${:}\longrightarrow$ $\sf x={\dfrac {-28}{-4}}$

${:}\longrightarrow$ ${\underline{\boxed{\bf x=7}}}$

$\therefore$ ${\underline{\boxed{\bf (x,y)=(7,-1)}}}$

The graph of an exponential function has a y-intercept of 7 and contains the point (4,112). Construct the exponential function T

blondinia [14]

The exponential function that describes the graph is $y=7\cdot 2^x$

The standard form of an exponential function is expressed as $y=ab^x$

a is the y-intercept

(x, y) is the point on the graph

Given the following expression

a = 7

(x, y) = (4, 112)

Substitute the given values into the exponential equation

$y = ab^x\\112=7\cdot b^4\\b^4 = \frac{112}{7}\\b^4= 16\\b =\sqrt[4]{16}\\b = 2$

Get the required exponential equation

Recall that $y=ab^x$ , hence the required equation will be $y=7\cdot 2^x$

I really need help i don’t understand !!!!!!

Answer:

y+2 = -4/5(x-3)

Step-by-step explanation:

The point slope form of a line is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

y - -2 = -4/5(x-3)

y+2 = -4/5(x-3)

IS IT CORRECT ILL MARK YOU BRAINLIST

Andrews [41]

Step-by-step explanation:

1 is wrong, because if it says the sum of 5 times the number m and 12 that means its 5(m+12)=27

because its the sum and then 5 times that

2. You got the right answer, its five times x squared plus 2 is 22
