Write a second equation whose graph goes through (0,1) so the system has no solutions.

Answers

Answer:

y = 5x + 1

Step-by-step explanation:

Hello There!

Equations that have no solutions are parallel

So the line we are going to create an equation for has the same slope as the line drawn

To find the slope we do change in y divided by change in x

as y goes 5 x goes up 1

so the slope is 5/1 or 5

The requirements for the equation is it has to go through the points (0,1)

The ordered pair listed is the y intercept so the equation would be

y = 5x + 1

the cost of 7 toys is AED 294. the cost of 5 toys. (Unitary method)

Answers

Answer:

AED 210

Step-by-step explanation:

If the cost of 7 toys is AED 294, this is written as;

7 toys = AED 294

To get the cost of 5 toys, this is written as;

5 toys = x

Divide both expressions

7/5 = 294/x

Cross multiply

7x = 5 * 294

7x = 1470

x = 1470/7

x = 210

Hence the cost of 5 toys is AED 210

Answer:

JL = 9√13

Step-by-step explanation:

All of the triangles in this geometry are similar:

∆MKL ~ ∆MLJ ~ ∆LKJ

Corresponding sides of similar triangles are proportional, so you can write the relations ...

JL/JM = JK/JL ⇒ JL² = JM·JK

LM/JM = KM/LM ⇒ LM² = JM·KM

Using the second expression to find JM, we have ...

JM = LM²/KM = 18²/12 = 27

We know that JK = JM +KM. Then the first expression can be ...

JL² = 27·(27 +12) = 9²·13

JL = 9√13

Sam and Ella were running in a race. Sam ran ⅞ of a mile and Ella ran 5/10 of a mile. At the end of the race they wanted to compare how far they ran. Ella said they could compare the fractions by comparing each fraction to ½. Show how Ella could compare 5/10 and ⅞ to ½ . Then explain who ran further and how you know.

Answers

Answer:

ELLA

Step-by-step explanation:

Given that :

Distance covered by Ella = 5/10

Distance covered by Sam = 7/8

Comparing each distance to 1/2

Ella = 5/ 10 = 1/2 ; 1/2 = 1/2 = 0.5

Sam = 7/8 = 0.875 ; comparing with 1/2

0.875 > 0.5

Given

Sam ran farther Than ELLA

Because 0.875 > 1/2

0.875 - 0. 5 = 0.375

What is the measure of angle B in degrees?

Answers

Answer:119

Step-by-step explanation:

edge 2021

B = 119 degrees

A straight line is 180 degrees
The 112 degree angle and angle C make up a straight line, so 112+C = 180
c = 68 degrees

The sum of a triangle’s angles also equal 180 degrees, so angle A + angle B + angle C =180
This means 51 + 68 + A = 180
119+A=180
A = 61 degrees

Now knowing angle A, and knowing that a straight line is 180 degrees, you can solve for angle B

A+B =180
61+B=180
B=119 Degrees

a flomming tile has the shape of a parallelogram whose base is 24cm and height is 10 cm how many tiles are required to cove the floor of area 1080m2

Answers

Answer:

4 1/2 tiles are needed to cover this area

Step-by-step explanation:

Mathematically, the area of a parallelogram is the product of the base and the height

We have this as;

24 * 10 = 240 cm^2

So the area of a tile is this

The number of tiles that will cover the given area will be;

1080/240 = 4.5 tiles

Select all of the following that are potential roots of p(x) = x4 − 9x2 − 4x + 12?

Answers

Answer: roots are 2, -2, -3, and 3

Step-by-step explanation:

I'm presuming the equation is x^4-9x^2-4x+12

so first group the equation by factoring out the GCF of the first two terms and last two terms

x^2(x^2-9)-4(x-3)

x^2(x-3)(x+3)-4(x-3)

(x^2-4)(x-3^2)(x+3)

(x-2)(x+2)(x+3)(x-3)^2

The potential roots of the function p(x) = x⁴ - 9x² - 4x + 12 are x = 1, -2 and 3.

What is the degree of a polynomial?

Degree of a polynomial is the highest power of the variable in that polynomial. For example, in a cubic polynomial, the variable [x] has the highest power of 3.

Given is the following function with degree of 4 as -

x⁴ - 9x² - 4x + 12

We will plot the graph and find the roots of this function. The number of x - intercepts [coordinates where the graph cuts the x axis] will give us the roots or zeroes of the polynomials. Refer to the graph attached, it shows that the graph intercepts the x - axis at three different coordinates which are → x = 1, x = -2 and x = 3. Hence, these three values of [x] are the potential roots of the function p(x) = x⁴ - 9x² - 4x + 12.

Therefore, the potential roots of the function p(x) = x⁴ - 9x² - 4x + 12 are x = 1, -2 and 3.
