The equation with no fractions is:

30x + 80 = 36

Solution:

Given that the equation is:

$\frac{3}{4}x+2=\frac{9}{10}$

We have to rewrite the equation such that there is no fraction

From given expression,

$\frac{3}{4}x+2=\frac{9}{10}$

Simplify the left hand side of equation

$\frac{3x+8}{4} = \frac{9}{10}$

Cross multiply to get a simpler equation

$10(3x+8) = 9 \times 4\\\\Simplify\ the\ above\ expression\\\\30x + 80 = 36$

Thus the equation is rewritten with no fractions

Mary eats 5 bananas and an additional 2 bananas when she works out for 2 hours. Represent the number of bananas that she eats wh

ElenaW [278]

For this item, we let x be the number of hours she works out and y be the total number of bananas that she will be eating after the workout. The expression that best described the given above is,
y = 5 + 2x
5 is given as the y-intercept because of the initial condition.

Y=9x+4 is translated 4 units , what would be the equation on a graph?

denis-greek [22]

I noticed that this equation is in slope-intercept form (y = mx + b). M = the slope of the line, B = the y-intercept.

If the line is translated (fancy, fancy, talk for MOVED) up. The Y-intercept would change positive (because it is moved up) by four.

4 + 4 equals...well, 8.

Hope I could help you out! If my answer is incorrect, or I provided an answer you were not looking for, please let me know.
However, if my answer is explained well and correct, please consider marking my answer as Brainliest! :)

Have a good one.

We performed the following operations:

$f(x)=\sqrt[3]{x}\mapsto g(x)=2\sqrt[3]{x}=2f(x)$

If you multiply the parent function by a constant, you get a vertical stretch if the constant is greater than 1, a vertical compression if the constant is between 0 and 1. In this case the constant is 2, so we have a vertical stretch.

$g(x)=2\sqrt[3]{x}\mapsto h(x)=-2\sqrt[3]{x}=-g(x)$

If you change the sign of a function, you reflect its graph across the x axis.

$h(x)=-2\sqrt[3]{x}\mapsto m(x)=-2\sqrt[3]{x}-1=h(x)-1$

If you add a constant to a function, you translate its graph vertically. If the constant is positive, you translate upwards, otherwise you translate downwards. In this case, the constant is -1, so you translate 1 unit down.

Three added to eight times a number is the same as three times the value of two times the number -1

emmainna [20.7K]

Answer:

The number x is -3

Therefore x=-3

Step-by-step explanation:

Given problem is "Three added to eight times a number is the same as three times the value of two times the number -1"

Let x be the number

It can be written as

$3+8\times x=3(2\times x-1)$
