Step-by-step explanation:

Answer:

AnswersMathsGCSEArticle

What are the values of x and y?

a) 3x + 5y = 26

b) 2x + 2y = 12

Step One: We need to find a way to equate either the x terms of the y terms in each equation. Multiply equation a) by 2 and equation b) by 3 to form the following equations.

a) 6x + 10y = 52

b) 6x + 6y = 36

Step Two: Take equation b) from equation a) to eliminate the x component.

a) 6x + 10y = 52

- b) 6x + 6y = 36

0x + 4y = 16

y = 4

Step Three: substitute the value of y into either equation to find the value of x.

b) 2x + 2y = 12

2x + (2x4) =12

2x + 8 = 12

2x = 4

x = 2

x=2 y=4

Simplify: (-2x)4 help me with this!

Answers

Expand (-2x)^4

(-2)^4 x^4

-2^4= 16

=16x^4

Hope this helps

The simplification of the given equation [tex](-2x)^4[/tex] is [tex]16 * x^4[/tex].

Exponents are mathematical notation used to indicate repeated multiplication of a number or expression by itself.

They are written as superscript numbers or symbols placed to the right and slightly above the base number or expression.

To simplify (-2x)^4, you can apply the power rule for exponents.

(-2x)^4 can be expanded as follows:

(-2x)^4 = (-2)^4 * x^4

Now, evaluate the exponent of the base -2 and x:

(-2)^4 = 16

Thus, the simplified expression is: [tex](-2x)^4 = 16 * x^4[/tex]

I need help finding the slope, The y-intercept, and the equation??

Answers

Answer:

y intercept is (0, 1)

slope is 3

equation is y = 3x +1

Step-by-step explanation:

You find the y intercept when x equals 0 and you can see that on the table that is 1.

You find slope by y2-y1 divided by x2-x1. if you pick (0,1) and (1,4) it is 4-1/1-0 which equals 3.

Therefore the equation is y = 3x + 1 in slope intercept form because the slope is 3 and y int is 1.

What is the value of x in the y = 2/3x + 5 when y=7?

Answers

Answer:

x = 3

Step-by-step explanation:

y = 2/3 x + 5; y = 7

7 = (2/3)x + 5

2 = (2/3)x

x = 2 * 3/2

x = 3

Answer:

x=3

Step-by-step explanation:

To start all you need to do is replace [tex]y[/tex] with 7 to get [tex]7=\frac{2}{3}x+5[/tex]

Then, you need to isolate x on the right side of the equation, starting with subtracting 5 on both sides to get [tex]2=\frac{2}{3}x[/tex]

Finally, you divide both sides by [tex]\frac{2}{3}[/tex]. You divide fractions by multiplying the reciprocal like so [tex]\frac{2}{1} *\frac{3}{2} =x[/tex] to get [tex]\frac{6}{2} =x[/tex]. This means that x=3

PLS HELP!! Lin ran 2 3/4 miles in 2/5 of an hour, Noah ran 8 2/3 miles in 4/3 of an hour, How long would it take Lin and Noah to run 1 mile at that rate? PLS ANSWER!!

Answers

Answer:

Lin will run 1 mile in 8/55 of an hour

Noah will run 1 mile in 2/13 of an hour

Step-by-step explanation:

Here;

Lin ran 2 3/4 miles in 2/5 of an hour

he will run 1 mile in x hour

x * 2 3/4 = 2/5 * 1

2 3/4 = 11/4

x * 11/4 = 2/5

x = 2/5 * 4/11

x = 8/55 hour

For Noah

8 2/3 miles in 4/3 of an hour

1 miles in y hours

y * 8 2/3 = 4/3 * 1

y * 26/3 = 4/3

y = 4/3 * 3/26

y = 4/26 = 2/13

He will run 1 mile in 2/13 hours

The following figures are not drawn to scale but AB and CD are straight lines. Find x.

Answers

Answer:

uh I think x=25°

Step-by-step explanation:

2x+60°=110°(vertically opposite angles are equal)

2x=110°-60°

2x=50°

x=50°÷2

x=25°

A straight line equals 180 so O =70 and so does the angle across from it to add the knowing angles and you’ll get 310. Subtract this from 360 since that is the degree of a circle and get 50. So then your equation is 50= 2x and you divide and get x=25
