The zeros of a parabola are 6 and −5. If (-1, 3) is a point on the graph, which equation can be solved to find the value of a in
Elena L [17]

ANSWER

3= a( - 1 +6)( - 1  - 5)

EXPLANATION

The equation of a parabola in factored form is

y = a(x + m)(x + n)

where 'a' is the leading coefficient and 'm' and 'n' are the zeros.

From the question, the zeros of the parabola are 6 and −5.

This implies that,

m = 6 \:  \: and \:  \: n =  - 5

We plug in these zeros to get:

y= a(x +6)(x  - 5)

If (-1, 3) is a point on the graph of this parabola,then it must satisfy its equation.

We substitute x=-1 and y=3 to obtain:

3= a( - 1 +6)( - 1  - 5)

The first choice is correct.

Solve for z. 5z − 6 − 34 = zz − 6
valkas [14]

Answer:

z=\frac{17}{2}

Step-by-step explanation:

5z-6-34=z-6

combine like terms (-6-34)

5z-40=z-6

subtract z on both sides

5z-z-40=-6

4z-40=-6

add -40 on both sides

4z=34

divide both sides by 4

\frac{4z}{4}=\frac{34}{4}

z=\frac{17}{2}

hope this helps

4/5 ÷ 7/30 please hellllpppp
Softa [21]

Answer:

\frac{24}{7} or 3\frac{3}{7}

Step-by-step explanation:

\frac{4}{5}\div \frac{7}{30}

Step 1: Apply the fraction rule: \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}

=\frac{4}{5}\times \frac{30}{7}

Step 2: Cross-cancel common factor: 5

=\frac{4}{1}\times \frac{6}{7}

Step 3: Multiply fractions: \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}

=\frac{4\times \:6}{1\times \:7}

Step 4: Multiply the numbers: 4\times \:6=24

=\frac{24}{1\times \:7}

Step 5: Multiply the numbers: 1\times \:7=7

=\frac{24}{7}

Therefore, the answer is \frac{24}{7} or in the simplified form; 3\frac{3}{7}
