Answer:

The length of JM is 40

Step-by-step explanation:

Since 7x+5 and 8x are both equal, we can make this equation:

7x+5=8x

-7x     -7x

x=5

7(5)=35

35+5=40

Write an equation of a piecewise defined function with the given conditions: domain is (-3, 2) u (2, ∞) range is (-1, ∞) functio
Korvikt [17]
\left \{ {{f(x)=x+2, -3\ \textless \ x\ \textless \ 2} \atop {f(x)=x-2, 2\ \textless \ x\ \textless \ infinity}} \right.

f(x) has to be close to -1 when x is close to -3, and so f(x) is increasing when x increases, and there are no numbers from -1 to ∞ that there is no f(x) value. In the first piece of the function <span>f(x) ranges from -1 to 4 and the second piece from 0 to ∞ so. The ranges had to overlap since it's not defined at x = 2.</span>

n considering the cross YyRr x YyRr, the phenotype ratios of the F2 generation will be _____. 1:3:1 3:1 9:3:3:1 4:1
Marrrta [24]
The cross of YyRr will produce 16 distinct genotypes.

If the two alleles are far enough on the same chromosome, then the Y and R alleles will be distributed independently of one another, so that the genotypic ratio among each allele would be 1:2:1 (YY:Yy:yy, and similarly for the R allele). Then the dihybrid cross will yield a genotypic ratio of 1:2:1:2:4:2:1:2:1 (YYRR:YYRr:YYrr:YyRR:YyRr:Yyrr:yyRR:yyRr:yyrr).

Now, assuming perfect Mendelian inheritance (complete dominance), the phenotypes exhibited by YY and Yy will be considered equivalent, and similarly for RR and Rr, so the phenotypic ratio would be 9:3:3:1 (YR:Yr:yR:yr).

Determine the discriminant for the quadratic equation 0 = –2x2 + 3. Based on the discriminant value, how many real number soluti
Margarita [4]

we know that

In a quadratic equation of the form ax^{2}+bx+c=0 the discriminant is equal to

(b^{2} -4ac)

if  (b^{2} -4ac)> 0 -------> the equation has two real number solutions

if  (b^{2} -4ac)= 0 -------> the equation has one real number solution

if  (b^{2} -4ac)< 0 -------> the equation has two complex number solutions

In this problem we have

-2x^{2} +3=0

so

a=-2\ b=0\ c=3

substitute in the formula

(0^{2} -4(-2)(3))=24

24 > 0 ---->  the equation has two real number solutions

therefore

<u>the answer is</u>

the equation has two real number solutions
